As Li Ye expected, the envoys who went to Bohai Kingdom brought back the news in a few days. The Bohai King Da Weiying was willing to resign to the Tang Dynasty and obey the Tang Dynasty's edicts. The envoys from the Bohai Kingdom were also returned together.

Li Ye did not summon the envoy of the Bohai Kingdom in Liaodong City, but arranged for the other party to go directly to Chang'an to pay tribute. As for the letter of nationality presented by the envoy, the suggestion that the king of Bohai, Daweiying, could send military monks to fight with the Tang army, but Li Ye politely refused.

He looked down on the power of the Bohai Kingdom, and most of the time he asked them to join the war was to be dragged down.

The next action was natural. The Tang army crossed the Yalu River in batches and rushed straight to the Datong River Basin.

At this time, the situation on the peninsula was the Post-Goryeo Dynasty established by Gongyi in the north, also known as Post-Goguryeo, and its territory was still the largest, the Post-Baoje Dynasty established by Zhen Xuan in the southwest, and the Silla Dynasty in the southeast.

Therefore, the first opponent that the Tang army had to attack was not much different from more than two hundred years ago. They were all Goguryeo. However, compared with Goguryeo back then, the current territory of Goguryeo is too small, and a large area of ​​land in the north was all in the hands of the Bohai Kingdom.

Because the upper reaches of the Datong River are in the hands of the Bohai Kingdom and the lower reaches to the sea outlet are in the hands of Hou Goguryeo, the first important goal of the army is Pyongyang City.

"Ten years ago, there were civil strife in Silla, and thieves were everywhere, and the riots were rampant. The one who took the lead in raising the banner was the current Hou Baekje King Zhenxuan. This so-called Hou Gogurye King Gong was originally a descendant of the Goguryeo royal family. The place where he raised his troops was not in the territory of the former Baekje, but in the north.

"Later, he gradually occupied the former large-scale territory of Goguryeo. After Zhen Xuan called herself Queen of Hou Baekje and also called herself King of Hou Goguryeo, she could be regarded as the throne of bloody achievements in many battles."

During the march and resting, Niudan talked to Ergouzi about the opponent to be cut off in this battle.

Nowadays, Niudan is no longer a Dutou, but a deputy commander. Ergouzi is already a commander. And because he has been in Chang'an Cultivation Academy for two years, his name has been changed, and he is called Xu Zhong, which is the surname plus ranking.

Both of them are now soldiers of the imperial guards and are stationed in Youzhou on weekdays. This time the army marched eastward, and they were mobilized by the imperial guards near the northern border, and they were also on the battlefield.

"Compared with the Khitans, aren't these Goryeo people much worse? It seems that the war will be smoother this time and it will be easier to get military achievements." Ergouzi laughed twice and was ready to go.

Niu Dan slapped him in the head and cursed angrily: "All the commanders are already commanders, why are they still so unsteady? On the battlefield, can they underestimate the enemy? All opponents are worth your efforts before they become dead!"

Ergouzi nodded quickly, but the laughter did not stop. Obviously, he didn't listen to Niu Dan's words, his face full of beautiful yearning for military merits.

Niu Dan understood Ergouzi's mood very well. After all, the other party had not been married for a long time, and had just had a child. Now he was full of ideas of making achievements and winning over a wife and protecting his future. This is how men are. After getting married, they think about developing their careers so that their wife can enjoy wealth and prosperity.

As a veteran, Niu Dan had to educate Ergouzi every day. The core was to let him be more at ease and not remember to fight desperately on the battlefield. Being able to go back alive is the greatest responsibility to his wife.

At this time, Goguryeo went to Gongren and learned about the coming attack of the Tang army.

As a descendant of a royal family, Gongyan is quite visionary and has a strong mind. Ten years of battles have also cultivated his heroic qualities in all aspects - although he has not won a territory of thousands of miles in his battles for ten years.

When the world attacked the Tang Dynasty, the one who sent monks to respond to the call of the Khitan was the Gongse.

The Silla dynasty is already corrupt, and the chaos in the country cannot be calmed down, so naturally there is no time to distract himself. Besides, the Silla territory is far away from the Tang Dynasty, while Baekje is in a corner and there are not so many ideas.

Only Gongren, who realized that he was the Goguryeo royal family, had a deep hatred left over from history with the Tang Dynasty. Emotionally, he did not want to see the Tang Dynasty become stronger again. From a rational point of view, if the Tang Dynasty restored its prosperity, it would be possible to send troops to Goguryeo again.

So he sent some monks to join the Khitan to join the grand ceremony.

Unfortunately, the final result was very bad. The huge offensive of attacks against the Tang Dynasty, not to mention that it failed to destroy the Tang Dynasty, or even prevented the Tang Dynasty from prospering, which made Gongyi very unhappy in the past two years.

Most of the reasons for unhappiness are caused by worry.

When he learned that the Tang army was attacking, the Gongren was almost shocked. After repeatedly confirming that the news was correct, he quickly summoned important officials under his command to discuss strategies to deal with the Tang army's attack.

Those civil and military officials who were in Goguryeo before were considered scattered. When they heard that the Tang Dynasty came to attack, most of them were frightened and were so scared that they could not come up with an effective strategy for a long time.

A small number of them were immersed in the glorious achievements of the past wars. They could not understand the power of the Tang Dynasty. They kept saying that soldiers would block the water and soil. This time, they must follow the example of the former king defeating the Sui army, killing the Tang army so much that it piled up like a mountain, and then building a capital temple.

Facing the noisy ministers, the gongren were extremely worried.

His family knows his own affairs, and not to mention anything else, he still knows how powerful the Khitan soldiers are and how powerful the cultivators are. Even the dilemma caused by the Khitans and the four parties were torn apart by the Tang army in less than a year. How dare he be arrogant?

Just when the Gongzi couldn't sleep at night, a turning point appeared.

The monks who went to spy on military information returned, saying that the Tang army only dispatched 100,000 infantry and cavalry to attack this time.

"Only 100,000 sprints?" When Gongyu heard this number, he seemed to be a person standing on a cliff. He suddenly realized that the so-called cliff was actually only one meter high and would not bring danger to him at all. He couldn't help laughing to the sky.

"I actually only launched 100,000 infantry and cavalry and rushed to attack us. This is too underestimated!"

"The Tang Dynasty was too proud and complacent, they just humiliated themselves!"

"A mere 100,000 soldiers are just here to die!"

After being informed by the Gongren, the civil servants and generals were almost excited at the same time. In their eyes, the Tang Dynasty was so proud that they did not take them seriously. This arrogant military strategy undoubtedly gave them a once-in-a-lifetime opportunity.

"King! The Tang Dynasty is too bullying, and the last general cannot tolerate it. Please ask the King Xu Mo to go to war. The last general will definitely let the Tang Dynasty know what the elite soldiers of a hundred battles are!"

"King, please be the pioneer!"

The generals were happy and immediately asked for battle. Even the most pessimistic people before, after learning that the Tang army had only 100,000, they had the will to fight.

Gongren was very satisfied with everyone's reaction. Goguryeo is indeed not strong at the moment, and is no match for Goguryeo more than two hundred years ago. If the Tang Dynasty had heavy troops attacked, he would really be in a state of ease.

But now it seems that the Emperor Li Ye of the Tang Dynasty was not as magical as others. After winning the war of attacking the Tang Dynasty, he was still as inevitable as others. Now he just wanted to destroy Goguryeo with only 100,000 troops. This is making a mistake and giving himself a chance!

The bowman smiled and twisted his beard to think for a while, but still thought it was not careless. The Tang army was still very powerful and had to do their best to defeat the Tang army cleanly and decisively, and beat the Tang Dynasty to the death. In this way, they knew that they were powerful and would no longer covet this land all day long.

Thinking of this, the Gongren began to point the general: "Pei Hyun-qing, I ordered you to be the defensive envoy of the North Camp, and to rush to Pyongyang City today to preside over the Pyongyang war. Shin Chongqian, I ordered you to be the Xuanfu envoy of the North Camp, and to cooperate with General Pei's battle. You two must not let the Tang army cross the Datong River during this trip!"

Pei Xuanqing is the most brave and good general under Gongyi, and Shin Chongqian is the most resourceful strategist under his command. If the two of them were sent together, Gongyi did not reserve the slightest reservation.

Pei Xuanqing and Shin Chongqian stood up one after another to receive the orders, both of whom were full of fighting spirit and confidence. "Don't worry, king, we will make the Tang army come and go without a return!"

In late July, the Tang army completed the assembly outside Pyongyang City.

After inspecting the city defense of Pyongyang, Zhao Polu turned around and reported to Li Ye: "Your Majesty, the city defense of Pyongyang is very tight. The moat has been urgently accelerated. After being dug deep, the city wall has been reinforced and raised a lot. Various defensive equipment is very complete. It seems that Goryeo has made up his mind to guard it strictly."

After the Tang army entered Goguryeo, they did not encounter any large-scale resistance along the way. The Goguryeo army, not to mention that the monks did not appear in the wild, even the several large and small cities in the border areas were directly abandoned by the other side.

It is obvious that Goguryeo concentrated its troops on the front line of Pyongyang City, in order not to give the Tang army a chance to defeat each one. The five fingers were clenched into fists, and the Tang army could not capture the strong city with an absolute advantage, and eventually they could only return without success.

Li Ye was not surprised by Goguryeo's strategy. This was a very wise choice. "How many defenders are there in Pyongyang?"

Zhao Polu replied: "According to the observation of the last general and in all aspects of information, there are no less than 200,000 defenders in Pyongyang City, and there are no less than 50,000 elite troops in each of the two acropolises!"

Pyongyang City and the two acropolis, the left and right, form a defensive system with the help of the terrain, which serves as a supporter for each other, which is quite difficult to solve from a strategic perspective.

Li Ye showed an inexplicable smile, "Faced with 100,000 infantry and cavalry, 300,000 soldiers and horses actually stood in the city and guarded me. I have been considering to have many battles in my life, but I have never fought such a strange war."

Zhao Polu naturally understood Li Ye's meaning, and also smiled and said, "If it were in our country, war would naturally not be like this. The Tang people did not care about being a turtle with their heads. According to my opinion, these Goryeo people were probably scared..."

The troops of the siege must be several times that of the defending city. This is the norm for war. Without the enemy's troops several times that of the enemy, you dare not attack and defense. Similarly, if the defensive party has several times the troops, it will not defend the city walls to death, but will take the initiative to fight with the enemy in the field.

After all, although defending the city takes advantage, it will greatly harm the city itself. The houses and buildings in the city will suffer great losses in the war. Therefore, guarding the city is often the last tactic that is forced to adopt.

Li Ye waved his hand and signaled Zhao Polu without saying much, and said directly: "Goryo thinks that a turtle can save his life if he is a turtle, but he doesn't know that the turtle shell must be hard enough. He ordered the three armies to attack the city tomorrow. I want the people of Goryo to know that the 70,000 infantrymen in the Tang Dynasty are enough to conquer any strong city in the world!"

"I accept the order!"
