Compared with the Tongwan City of Helianbo, the four walls of Yunzhou were not much inferior. Even though it was abandoned for more than 40 years, when Yunzhou was still in the hands of the Tang Dynasty, it repaired the rammed earth wall when the Northern Wei Dynasty was built. The solid foundation made Du Shiyi less effort. In addition, Yunzhou is located in the north, and the rain is already sparse than in the south of the Yangtze River. Even the strong men can use awl to make shallow holes, let alone other means of destruction.

However, after the Northern Wei moved its capital to Luoyang, in order to cut off the wish of the Xianbei nobles to return north, Emperor Xiaowen once ordered the reconstruction of the southern wall of the ancient capital Pingcheng and reduced its area. Although this matter was not completely completed, Yunzhou has always been aimed at defending enemies to the north. After attacking Liu Wuzhou in the early Tang Dynasty, the southern wall of Yunzhou was destroyed again. It can be said that the latest place in the entire Yunzhou is here.

For the city wall, the latest does not mean the most solid. It is like Sima Chengzhen followed Du Shiyi to inspect the four walls. When he finally arrived at the south wall, his brows frowned. He was good at face to face but rarely showed off to others, let alone such a magical method as showing off. However, Du Shiyi noticed his repeated actions of looking at the sky, and finally couldn't help asking: "Is Sima Sect Master observing the celestial phenomena?"

"The moon sets and the stars sink, which cannot be calculated by human resources. What's more, I am not the famous Li Taishi who wrote "Yi Si Zhan" back then. On the day of your marriage, the comet was invading Ziwei. Your Majesty was eager to summon me, but I was not able to seize the responsibility of the Grand Historian. What is it that people say, how can I do it?" Sima Chengzhen smiled distractedly. Seeing Du Shiyi was stunned at first, he suddenly realized it. He thought that he understood the reason why the Golden Immortal Princess Yuzhen Princess Gu'an Princess, then he smiled, "I have lived in seclusion in the mountains for decades, and I am not good at astrology, but I have some experience in observing clouds. When I was in Tiantai Mountain, I also recorded a Guanyun Record."

It is said that old horses know the way. Many experienced farmers and herders are often able to distinguish the impact of various cloud changes on the weather. However, those who would record in detail with Sima Chengzhen and also write books to analyze are probably rare. So, Du Shiyi immediately became alert and asked, "Was the sect leader now gaining something to watch the clouds?"

"Otherwise, why do you think I want to turn against you? In the middle of the night, I will disturb you and take me, the old man, to run around?" Sima Chengzhen saw Du Shiyi suddenly realize, and thought for a while, and finally said, "I don't want to know what the strategic plan you have discussed is. But from the time I arrived in Yunzhou in the daytime, to the Yun I saw at this moment, the weather will change suddenly within one day. At least 50% of the time, it will snow in one day."

It snows? It snows at this time? It snows when the military and civilians in Yunzhou City were buying rice at high prices, and they were going crazy and just as the autumn harvest was almost over. How could this be possible

If it weren't for Sima Chengzhen, no one who was talking nonsense, Du Shiyi would never believe it. However, the snow in June is not the only one injustice of Dou E. What's more, July, although it's a decade or even hundreds of years, it's definitely not impossible to encounter it. The 50% chance of snowing is definitely not something that can't be ignored for Yunzhou City at present. So he turned around and stared at Sima Chengzhen and asked again: "Sect Master, do you mean that even if it doesn't snow, the weather will be cold in an instant? It's caught people off guard?"

"There should be 70% of the chance of sudden cold. Now, the wind direction has changed."

Du Shiyi, who had not paid attention to the change of wind during the day, did not notice it at all. However, since he handed over his troops to an expert like Wang Zhongsi, he decided to believe Sima Chengzhen's ability to observe the clouds. However, when he thought that the sudden cold weather would bring extraordinary consequences to the Yunzhou military horses, when the city was still calm from now on, he immediately sent Sima Chengzhen back to the Governor's Office, and immediately attracted the most trustworthy Chibi and ordered him to go quickly to inform Wang Zhongsi. Thinking that he intended to stock up a lot of furs that had been traded with the Khitan on Baideng Mountain, he had to ask Wang Peiyi to prepare to support Wang Zhongsi, and finally sent someone to Taiyuan Prefecture to report the news.

After all, although the Bingzhou Grand Governor's Office has become the Northern Capital Taiyuan Prefecture, it still surpasses the entire Hedong Road prefectures and counties. Now no one suspects that he is exaggerating. As for whether Taiyuan Yin and the officials of Taiyuan Prefecture know whether the Jinxian Princess Princess Yuzhen and Sima Chengzhen pass through, what is the reaction now? He doesn't care about it.

He remembered very clearly that when Emperor Gaozu of Han, Liu Bang, was trapped in Baideng Mountain, it was raining and snowing for days, so that Chen Ping's plan finally caused the Huns to retreat, but the Han army still suffered heavy losses. I just hope that Wang Zhongsi could listen to his reminder and use the furs stored in Baideng Mountain to keep warm in time.

Therefore, when he returned to the Governor's Mansion and Yi Sleeped, and after only two hours of sleep all night, after he woke up in a daze, he came to the window with his clothes and his shoes in his sleep. But after he opened the window for a short while, he keenly felt the chill coming to his face. It did cool down. Although it was not too cold, it further proved Sima Chengzhen's inference.

In the cold weather, is there a battle to defend Yunzhou?

After turning around and tidying up his clothes and putting on the scorching official robe, Du Shiyi ordered in a deep voice: "Come here."

As a figure pushed the door and saluted, Du Shiyi couldn't help but be stunned: "Jiyun? Why are you?"

Unlike him who gave Chen Baoer a scientific name, but he still habitually nicknamed him Baoer. Since he officially gave Nanba a scientific name, Nan Jiyun, Du Shiyi has always called him with the word Jiyun. At this moment, Nan Jiyun lowered his head and held the tea tray, and then whispered: "Uncle Chibi left the city and public servants, and everyone else has their own responsibilities. Only I am idle and have nothing to do. Since I am a guard, I will serve as a servant of Du Changshi."

Although it seemed as if nothing was wrong at first glance, Du Shiyi heard a sense of unwillingness to accept it after careful discerning. He didn't speak, but just looked at the boy thoughtfully until Nan Jiyun's face rose red, and he asked lightly: "Why, do you think I won't let you go to fight with the army, so I'm not convinced?"

"Jiyun dared not." Nan Jiyun raised his head suddenly, gritted his teeth and said, "It's because Jiyun is not good at martial arts and has no military skills. Besides, he has never experienced a battle formation..."

"No, you have experienced the battle formation. In the night battle that night, you captured the thief's head alive and made great contributions. The reason why you did not reward me is that killing the thief's head is not a great merit. But" Du Shiyi interrupted him, turned around and sat down on the main seat, and then asked, "Didn't you think about how many people there are in Yunzhou City today?"

"This" Nan Jiyun was stunned at first, and then his face changed suddenly, "What Changshi meant is that

"Yunzhou is almost an empty city now, and the original strategy of seducing the enemy is impossible to use. After all, there are four thousand people living in Yunzhou City. If you can't make a place as big as before, you can close the door and fight dogs. The most important thing is that the remaining military horses in Yunzhou City are fewer than the previous night before, and there are still many casualties and injuries, not to mention that there are more troops and horses in addition to the three Turks. If at that time, General Wang, General Luo, General Hou, are all away on the four walls, do you think that in Yunzhou City, who can stand alone in the arrows and stones except the Lord and me?"

Nan Jiyun felt a stream of blood in his chest rushing into his brain, and he stepped forward quickly and blurted out: "I

"Very good, ambitious." Du Shiyi immediately showed an excited expression when she saw him, and couldn't help but smile, "Okay, from today on, the whole city will be martial law and follow me to climb the city wall."

Although Sima Chengzhen was not able to calculate, he guessed that in addition to the other enemy of the three Turkic tribes, he finally appeared at noon after the four gates were closed in broad daylight on Yunzhou. Although Vijay Khan once contemptuously regarded the Xi people and Khitan as slaves in conversation with the envoys of the Tang Dynasty, there were also many fights among the three tribes, so at this moment, Du Shiyi could not tell which clan it was from.

When one of the riders shot an arrow on the wall with an arrow. Although it was just a tentative arrow, Nan Jiyun, who had run across two hundred steps, immediately changed his expression. Not to mention the accuracy, he did not have such arm strength yet, although he had a famous teacher, he had learned too short, and his family was poor, and his body had just grown tall and strong in Yunzhou in the past few months... However, even with such self-knowledge, looking at the power of the arrow, he still felt an irresistible desire to try. This is the battlefield, this is the battlefield to defend the country.

Du Shiyi saw this change. After all, Nan Jiyun is not the most powerful confidant general around Zhang Xun, nor is he the famous Suiyang general who was angry because Helan Jinming refused to send troops to help, and turned around and shot the pagoda. Half of the arrows were gone, and the arrows were almost invincible. But in the end, the heroic spirit was already rooted in his heart.

Seeing the overwhelming rain of arrows pouring down the city wall, Du Shiyi, who was avoiding the arrow tower, saw that the catapult had already started to operate, shouted sternly to the left and right: "Behind you are Yunzhou, your wife and children, old and young

If you retreat, you will die for half a day, and General Wang will return to the army, which will make it difficult for the enemy to take care of the beginning and end.”

At this moment, the one who followed him was the most loyal wolf guards carefully selected by Princess Gu'an, and the one who followed the longest among his followers. The loud bang Yingnuo, amid the overwhelming sound of arrows breaking through the air, immediately came into the ears of the soldiers who were in a panic on the city wall.

Although Yunzhou City has been relocated for only half a year, with the intention of the saint, Du Shiyi has designated two entire lifangs as workshops early, and all the craftsmen recruited are among them. He gave these craftsmen the best treatment, but temporarily restricted the freedom of these people. Therefore, he did not have time to produce the crossbows on a large scale immediately, but he prepared a total of twenty catapults early and prepared a certain number of stone bombs. The assembly started this morning did not take much time, but launching the catapults in the rain of arrows was enough to cause deep panic among the soldiers who had never really experienced the battle formation.

Most of the military and horses in the city have already left the city, and they have to only a few hundred people. Can they really defend Yunzhou?

At this moment, a relay roar came from the arrow towers one by one.

"Behind you, Changshi Ling, is Yunzhou, your wife and children, your children, you will live if you advance, and you will die if you retreat.

As long as you keep it for half a day, reinforcements will come.”

With one roar after another, still unconcealed on the battlefield, thinking of the reward orders issued by Du Shiyi before, as veterans braved the rain of arrows to patrol the orders, the soldiers on the city finally gradually calmed down.

That's right, there are more than a thousand soldiers and horses outside the city that Wang Zhongsi had pulled out to train before. Just return to the army, which made it difficult to deal with the head and tail of this army that suddenly came to attack Yunzhou.

In Yunzhou City, when Chibi ordered the whole city to search for giant thieves yesterday when Princess Yuzhen and others arrived at the Governor's Office, and then when the young and strong preparations were being summoned in the market, the people had already noticed a bit of unusual meaning. Although Yunzhou, like other prefectures and counties, although Du Shiyi's rule was decisive, it was extremely friendly to the people most of the time. During the Dragon Boat Festival, the Governor's Office even sent small rice dumplings in front of the door like a Buddhist alms, which made many people happy. The sudden tension this time suddenly appeared like a heavy cloud pressing on people's hearts.

So, the sound of arrowheads breaking through the air and shouting of killing outside the city not only confirmed people's hidden worries, but also made many manic people unable to bear it anymore. In the Lifang adjacent to the arch where the Governor's Office, a sturdy man opened the door and saw the panic-faced Little King, and he couldn't help but turn around and curse at an old man in the house: "What kind of land is divided and what official gives to the house? I know that there will be no such good things in the world. What's wrong with being our tenant farmers in Shuozhou? Even if it is a bit harder, he will not lose his life or his hometown is hard to leave. Shuozhou is our hometown. When he comes back to Yunzhou, he is looking for death."

Hearing this, Chen Baoer, who was ordered to summon the young and strong to prepare for the city defense, felt very uncomfortable. Especially when he saw that the man was actually angry and pulled the old man out, he cursed and scolded him again, and even wanted to attack the old man, he finally couldn't help it. He stepped forward and grabbed the man's right hand and shouted sternly: "Stop."

"Why, Yunzhou can't be defended anymore. Now you still have time to manage my family affairs?" Chen Baoer is almost the most exposed person in the Yunzhou Governor's Mansion, except Wang Zhongsi. But at this moment, everyone respectfully called him Chen Jishi or Chen Xiaolangjun, but instead attracted the man's more contemptuous eyes and a more vicious sarcasm, "You little kid, if you have time to meddle in other people's business, it's better to go back to the Governor's Mansion and tremble with a cat."

However, he thought he could shake Chen Baoer's hand away at once, but with enough strength, the seemingly thin hand still tightly wrapped around his wrist. He was so angry that he was about to fight back, but he felt a strong force coming from his shoulders. When he was about to resist, he felt a sharp pain in his abdomen, and he was directly knocked to the ground, falling to the ground. At this time, he realized that there were still a lot of young and strong around him, and everyone's faces were filled with fear and anxiety.

"Who said that Yunzhou cannot be defended?" Chen Baoer did not realize that his voice became extremely sharp in an instant. "Chief Du personally went to the south city of Yunzhou, which had the weakest defense. The Lord personally visited the north city to supervise the battle. The other two walls, several soldiers from the Yunzhou Governor's Office, had rushed to take charge. They were just one or two thousand enemy enemies. They could not attack Yunzhou. Now they summoned you, not to let you die. The army members enjoyed the military pay for recruiting soldiers, and their families also enjoyed various discounts for rent-free and mediocre adjustments. They would naturally fight to the last one. You are just responsible for preparing sandbags. If the enemy enemy enters the city, what would the end? Mrs. Du was a woman and was still comforting the people in the city. At this time, they would only blame the world. You are still not a man."

The man lying on the ground was speechless, and the old man who had just been speechless by his fierce words suddenly paused his crutch and burst into tears. He said in a crying voice: "When a tenant is alive, but there are no wars but floods and droughts, and even human disasters. Ask yourself, how did your brothers die, how did your wife die? When you first arrived in Yunzhou to divide houses and land, how were you happy? What did you say? Now you are saying such despairing words, you are such a useless thing, if you don't want to serve as a service, I will take my old bones for you."

The young and strong around listened to the father and son's words, and thought about Chen Baoer's words. He saw that the old man in his early sixties threw his crutch and wanted to join his ranks. He didn't know who blurted out: "If Yunzhou City is broken, no one can get it. What strange things are there at this time that horse thief was so fierce before, and wasn't it that Du Changshi used a trick to defeat him? We can fight too."

With one, two or three agreeing, the young and strong man who was reluctant to be recruited finally burst out with blood and determination. Tang Zhen and Tang Xiu, who were like Chen Baoer following the crowd, saw Chen Baoer hurriedly leaving with these people. Tang Zhen couldn't help but whisper in a very impure Chinese: "Young man, can you really keep it?"

Chen Baoer didn't even look at the dumb man on the ground, and used all his strength to burst out a word: "can"

Seeing that the emperor and the next were very energetic, he immediately ordered: "The soldiers on the city wall fought bloody battles, and asked the elderly, weak, women and children in various families to open the stove to prepare for food, and prepare for reception of the wounded at any time."

In the Governor's Mansion, Princess Gu'an personally visited the North City Wall to supervise the battle. Wang Rong went to the city to appease the people. Wang Han, Cui Hao and Guo Quan also had their own responsibilities. The only one who stayed in the Governor's Mansion was the only one who had just recovered from serious injuries. Du Shiyi gave a death order to stay in the mansion. Although Wang Lingran and Princess Yuzhen were also quite familiar with each other, they really didn't know how to get along with these people who had to experience the most thrilling golden branches and jade leaves inadvertently, so they could only use the excuse of patrolling the Governor's Mansion to avoid it. Therefore, listening to the vague shouts of killing, Princess Yuzhen couldn't help but hug Yunu tightly.

"Supreme True Master, the master will not be in trouble, right?"

Hearing Yu Nu's question, Princess Yuzhen couldn't help but smile bitterly, but finally cheered up and said, "Your master is blessed and lucky, and you can avoid many dangers when you encounter. Master, who won't be fine, do you think so.

Seeing Princess Yuzhen and Princess Jinxian, even Yunu looked at him with hopeful eyes, Sima Chengzhen couldn't help but shook his head and sighed: "Du Shijiulang is indeed not a premature death, so don't worry."

He said this, but he couldn't help but recite my Tao Te Ching gently in his heart. However, on the battlefield of real swords and iron horses, face, fortune-telling, are not the masters of everything. I just hope he is not wrong

Princess Jinxian was older after all. Seeing that Princess Yuzhen was worried, Yu Nu was stunned. She deliberately said: "Yuan Yuan still remembers when Brother and Aunt joined hands to seize the palace? That time, we were very scared when we were waiting in Grandpa's palace. At that time, the shouting for killing seemed even bigger, and the atmosphere in the palace was even more dull. At that time, I once told you that if you fail, let alone Grandpa and Auntpa and Brother, we have no future."

"Sister" Princess Yuzhen's eyes turned red. Seeing Princess Jinxian nodding at her with a smile, she took a deep breath and cheered up. "That's right, we have seen such strong winds and waves, what is it now? Huo Qing, go and tell Wang Lingran that if someone needs to be suppressed and comforted in the city, I will go with my sister. Since I have come, I can't just treat it as an idle meal."

The superiors attacked the plan, followed by the diplomatic army, followed by the troops, and attacked the city below. However, the barbarians had been trapped in the city of the Central Plains from the Xia, Shang and Zhou dynasties, not to mention that the siege ladders have been used proficiently. Since we have long predicted that the biggest shortcomings of Yunzhou are the lack of well-trained soldiers, this sudden approaching army immediately attacked the city after two rounds of arrow feathers. Sure enough, except for the catapult cart and boiling oil on the top of the city, there were only sparse and weak archery strikes back, which strengthened the belief of Yu Luoyu, the leader of the city commander.

Before dark, Yunzhou will go down until then. Even if the Turks win or lose, they are the ultimate winners.

Therefore, with a wave of his long sword, he almost pulled his throat and shouted in Turkic words: "After attacking Yunzhou City, the gains of the plunder belong to him."

In the past, when the soldiers on the grassland fought, even if they plundered good things, they would eventually fall into the pockets of the princes and nobles above. Therefore, as soon as these words were said, I had already heard that the wealthy soldiers in Yunzhou were immediately excited and screamed. One by one, one after another, followed the cloud ladder and rushed up Yunzhou City. Especially on the lowest south wall, there were even more densely packed ladders. Although the cloud ladders were pushed down from time to time and people fell from time to time, more people at the bottom still climbed up with red eyes.

As the first person jumped onto the city wall, the army horses at the bottom immediately cheered loudly. But at this moment, the man had not had time to be happy that he was the first person to climb the Yunzhou city wall. He saw a cold light flashing in his chest. Then, the people under the city clearly saw a sharp edge of the spear revealed from his back. As the spear tip suddenly shrank back, the guy who had just been considered lucky by many people fell straight from the high city wall, like a heavy stone hitting the ground.
