Murong Yi didn't wear much, but out of the habit of marching, he always carried a cloak by his side. However, he used to fight and followed the supply team, but he had never used it. He just threw it in the bag. At this time, he was just taken out for Feng Wuyou.

Feng Wuyou was not polite. Because of his physical condition, women are indeed more afraid of cold than men. Moreover, Murong Yi has higher martial arts skills than her and has internal strength. This coldness is nothing to him.

"We must speed up our trip. We must find a village to stay in tonight and never camp in the wild." Murong Yi said while handing the cloak to Feng Wuyou.

"Why?" Feng Wuyou tied his cloak and asked a little strangely.

She would never think that Murong Yi said so because he could not endure hardships, because they had been camping outside many times along the way, and Murong Yi never complained once. There must be a reason for him to say this now.

Murong Yi looked up and said indifferently: "Because the weather is about to change."

Upon hearing this, Feng Wuyou immediately raised his eyes and urged Murong Yi to continue speaking with his eyes.

"The wind is strong, the cooling is in the afternoon, the clouds are thick in the sky, and you can see the spiders over there."

They were resting in a leeward place. A spider was making webs not far away, but it was not an ordinary web, but layer after layer, four or five layers. The web looked white and almost all the thickness could be seen.

"The spider has heavy webs, which will be a sign of the great cold wave weather. The temperature will definitely drop sharply tonight. With our current clothes, we cannot resist such coldness at all. Even if we camp outside, we will definitely be seriously frostbite. So no matter what, we must find a village to spend the night."

Murong Yi said, but one messy and broken fragment after another flashed through Feng Wuyou's mind.

Fire, burning mountain walls, combustion aids...

Strong wind, cold current, cooling...

"Oh no!" Feng Wuyou screamed suddenly, turned over the horse, and shouted sternly: "Everyone gets on the horse, go back to the fairy's pass!"

Her actions scared all the other three people. Nie Zheng was slightly stunned and immediately turned over. Anyway, he followed Feng Wuyou's life and did not ask the reason at all. The only important task he came out this time was to ensure Feng Wuyou's safety.

But Changsun Yunwei frowned and said, "Feng Wuyou, you are shocked, what the hell is going on!"

"If the people of Beiliang want to attack Fairy Pass, we must go back immediately!" Feng Wuyou said in a deep voice.

Upon hearing this, Changsun Yunwei immediately smiled: "Is this new? The people of Beiliang confronted our Daqin at Fairy Pass for a day or two, three days a small battle every five days a big battle every time. What's so strange about their siege!"

After all, it is a woman who has never seen the world before, and it is okay to fight small battles, but it is still rare to defend the country and borders.

"Wuyou, what happened?" Compared to Changsun Yunwei, Murong Yi obviously knew much about Feng Wuyou, and knew that she would never be so anxious because of a small matter. Now that she is like this, she must have thought of something. He doesn't mind returning to Fairy Pass, but he also has to figure out what is going on.

Feng Wuyouqiang explained as briefly as possible, "Most things in this world have a characteristic called heat rise and contraction. When the temperature is high, the volume of the item will grow larger, and when the temperature is low, the volume will shrink. If we heat something first and then cool down quickly, because the inside is still hot and expanding, but the outside is cold and shrinking, the heat and heat are uneven, cracks will occur, severely, and even explode. There is the simplest example. When you were a child, did you ever do a prank of throwing a cup that had just been poured overheated boiling water into the cold well water? What happened to that cup in the end?"

Changsun Yunwei's temperament was not worry-free at first glance. He had done this and immediately shouted: "I've played it. The cup was blown to pieces. Is it because of the heat and cold shrinkage? But what does this have to do with your return to the fairy?"

"This kind of heat-swelling and cold shrinking characteristics not only include porcelain, but also stones. We have seen it on the city wall today. People in Beiliang are burning the mountain walls with fire, and they will cool down tonight..."

Having said that, there was nothing I didn't understand. The faces of several people changed, and Nie Zheng's face turned pale. The Xiao family army was a team he regarded as brothers and sisters. But now, they were obviously trapped in a huge conspiracy, which could even drag all of them to death.

Changsun Yunwei murmured: "They heated up the mountain walls, and the temperature dropped sharply at night, and the mountain walls..."

"The mountain wall will explode, and the city wall connecting the mountain wall will be damaged without support. The worst thing is that the Xiao family army does not know about this. If the people of Beiliang take advantage of the situation to attack, then the Xiao family army..."

"Stop talking, let's go!"

Changsun Yunwei was so dark that he caught the horse and turned over.

No matter how he doesn't like Xiao Jinglan or doesn't like the Xiao family army, it's impossible for him to watch the people of Beiliang enter.

At this moment, he was just a soldier from the Western Qin Dynasty, not Changsun Yunwei.

Murong Yi had already landed on the horse. Feng Wuyou raised his whip and thrust hard. Suddenly, the four horses started almost at the same time, running back and forth like flying.

There must be no trouble, but there must be no trouble at the fairy gate.

At the same time, at about half a day, Li Feng Wuyou and the others were also rushing towards the border in the strong wind.

"Prince, the news from Nie Zheng is that the princess has arrived at Fairy Pass."

An old man who was about fifty years old but was energetic handed a note to Xiao Jinglan. This was the news that Nie Zheng sent with a hunting falcon after he arrived at the Fairy Pass. He had just arrived in Xiao Jinglan's hands.

Xiao Jinglan took a look, whispered lightly, signaling to know.

"Prince, there is another news." The energetic old man was naturally Yan Bo. He handed another note to Xiao Jinglan and said in a deep voice: "This news is not very good. The 100,000 troops of Beiliang have been assembled and are expected to arrive at Fairy Pass tonight."

Hearing this, Xiao Jinglan raised his head, and his face was handsome and sharp under the hood. The air-cooling here not only did not affect him at all, but instead highlighted his extraordinary temperament.

After looking at the direction of Fairy Pass from afar, Xiao Jinglan's pupils shrank sharply.

Along the way, he had hoped that his understanding of Feng Wuyou was wrong many times. Feng Wuyou did not go to Fairy Pass at all, but in the end, Feng Wuyou went there anyway.

She went to help him win over Xiao’s army, but at the same time, she also threw herself into a place of life and death.

Half a day, in just half a day, he can rush to Fairy Pass and see Feng Wuyou, but...

The people of Beiliang don’t give him this opportunity.

Xiao Jinglan suddenly turned his horse's head, and his voice was filled with a nearly cruel calm: "Go to Chenzhou!"

Weiyuan, Jitang, and Chenzhou are the three states adjacent to Tanzhou.

The attack of the people of Beiliang has been completed, and it is no point to go to Fairy Pass now. On the contrary, the terrain of Chenzhou is slightly prominent in the Western Qin section, and there is also a subtle spiral towards Fairy Pass. The Bailu Pass and Fairy Pass on the spiral horns have always been supporting each other and care for each other. If you want to break the siege of Fairy Pass, you can only go to Chenzhou and order the Bailu Pass soldiers to attack and cover it up from behind.

Only in this way can we truly win a glimmer of hope for Fairy Pass.

The person is right in front of him, but he can't go.

For her, he must go against her.

Xiao Jinglan lifted the reins of the horse, which immediately increased the speed.

He didn't look back at all, because as long as he looked back, he would probably think of nothing and come to her first and protect her firmly.

Uncle Yan looked at Xiao Jinglan's back and followed silently.

The prince is really carrying too much and too tired.

Princess, if you survive this time, don’t make trouble with the prince again.

Although it is a bit selfish to think so and is not very fair to the princess, it is much better to share the burden with the two people than to let the prince suffer alone.

Fairy Pass.

Nie Zheng looked at Feng Wuyou who had just left and came back shortly after leaving, and his face was full of confusion.

What is the princess doing? Didn’t she say she would help them solve the military supplies problem? Why is she back?

Could it be that I am afraid that it is too difficult to do, so I give up halfway? Then what I said before is all big talk?

Thinking of this, my face couldn't help but sink.

Feng Wuyou had no time to see his face, rushed into the central army tent and said directly: "Cheng Zhijie immediately ordered people to collect all the big stones and wood in the city and move them all to the city wall!"

It was already afternoon when they set off, and they delayed another two hours on the way. It was already evening and it was getting dark. At this time, it was too late to strengthen the city wall, so they could only move the materials to the city wall. Fortunately, the gap could be blocked immediately when the mountain wall cracked.

"It's inexplicable!" Cheng Zhijie was dissatisfied with Feng Wuyou's return, but now he is still in command, so he is naturally even more unhappy.

Feng Wuyou has no time to talk nonsense to him now. He pulled the token from Nie Zheng's waist and Liang was in front of Cheng Zhijie: "The token of the King of Qin is here. This princess orders you to do immediately as this princess says, sending all the big stones and wood to the city wall, and at the same time, he ordered the three armies to enter the first-level combat readiness. At midnight tonight, the people of Beiliang will definitely attack the city!"

Feng Wuyou said too surely, and Cheng Zhijie finally attracted some attention. Feng Wuyou's handling of Xu Youwei this morning impressed him deeply. She was so tough at this time, and she might have heard something.

He had this judgment for many years, so he immediately asked someone to continue his orders.

Feng Wuyou asked him to take him up the city wall again. When he walked up the city wall, Feng Wuyou finally explained the matter to him. When he heard the words "hot rise and cold shrink", Cheng Zhijie's expression became obviously solemn.
