It would be great if there was cement in the warehouse.

This was Sun Tu's first reaction at this time, because it was the fastest way to repair the city wall now. But unfortunately, at least until now, he has not found any shadow of cement in the system warehouse, and he is not an engineering student, nor does he have a cement formula - even if there is one, he has no time to create it overnight.

Now Sun Tu can only scratch his head there. After all, he is not a god. He really can't repair and perfect the city wall without materials. After seeing his helpless reaction, Peng Yongzhen was even more panicked and muttered: "What should I do? What should I do..."

The nervousness quickly spread out again, and now many soldiers around him felt panic, and many people were filled with despair and regret. The despair was that the city was difficult to protect. After all, the city walls were easily penetrated by the anti-army army before. Now there was such a big hole, and tomorrow's battle would inevitably be even more dangerous. Maybe the anti-army army would break into the wall in a battle; the regret was that their family had not worked hard to build the city earlier, and they would have to pay their lives now.

Sun Tu's face became more and more serious. Once the North Gate could not be defended, Changshu would inevitably be lost, and there would be only the option of breaking through. However, even if there were few casualties, he would inevitably be deliberately targeted by Zhu Jie when he returned to Jinling, and the situation would become more and more difficult.

"Sun...Sun Qianjun, the villain may have an idea to temporarily repair the city wall..." Someone suddenly whispered beside him, and it immediately made him feel refreshed when he turned to Sun Tu's ears. He quickly turned his head and looked over, but saw a Qingzhou military soldier who looked ordinary, lowering his eyes crampedly and did not dare to look at him.

"You really have a good idea? What's your name?" Sun Tu immediately grabbed his hands and asked anxiously. Not only Sun Tu, but also countless soldiers around him also set their eyes on the ordinary soldier, with expectations and doubts.

But this made him even more nervous. It was not until Sun Tu asked twice again that he hesitated: "The villain was poor a few years ago, and his house was broken and could not be repaired. It leaked in water in summer and air in winter. Later, he couldn't stand the cold anymore, so he thought of a stupid way..."

After hearing his slightly verbose explanation, Sun Tu's eyes suddenly lit up. Before the others could react, he patted the soldier named Qi San on the shoulder and praised: "You have saved my soldiers all over the city this time. I'll remember your contributions, and I will reward you very much!"

Qi Sanyi was also very excited when he heard this: "It is a blessing for villains to be able to help Chief Sun Qiang work, and I dare not ask for any reward."

But the generals such as Peng Yongzhen who had already reacted on the side were still a little suspicious: "Sun Qian, can this be done?"

"Of course, ordinary houses can be repaired in this way, and our city walls can be of course possible! And this works the fastest, and it's already very cold today, so you can try it."

"But this can only last for a moment... Once the weather gets hot, won't it be defeated?"

"Now, I will only solve the urgent problem. Let's leave other things to you later. Hurry up, please come and get water. You must repair the city wall before dawn!" Sun Tu's heart moved after a loud urging and said, "Not only can you use this method to break the city wall, but other places will also splash water on me!"

"Ah?" The soldiers were a little surprised and didn't understand what he was selling. But Sun Tu had no time to explain to them further: "As long as you do, this is a military order, and it is also the most effective way for us to resist the anti-military attack!"

Peng Yongzhen did not dare to disobey Sun Tu's orders anymore, and immediately turned around and ordered: "You might as well go quickly. If you dare to stay lazy, I will punish you severely!"

Even his own general said so, and no matter how doubtful the others had, they could only do so. After seeing them take action, Sun Tu quickly left and headed towards the east wall nearest, followed by the west gate and the south gate...

In the middle of the night today, Sun Tu rushed around the city and issued an order that many soldiers could not rest, asking them to get a lot of water nearby and spill it directly on the outside of the four walls.

So that night, the four cities in Changshu became large construction sites, and the sound of people working hard on the top of the city could be heard from afar. Even Wu Jun outside the city noticed the movement there, and specially sent a team to investigate the news, but was quickly shot by a burst of arrows and fled back.

But when Pang Wanchun learned of this information, it was already dawn, but with the darkness and distance, he did not understand what the Song army was trying to do in the city. He just felt a faint uneasiness in his heart.

It was not until the sky was bright and the Wu army launched an attack on the North Gate of Changshu again under the urging of the drums. When they thought that there were loopholes in the north wall, the soldiers rushing in front were surprised to find that there were quite a change in the Changshu wall today.

The city wall, which was damaged and mottled before, even had a large gap, became smooth and solid, and the gap was also filled, and it was shining with dazzling light under the rising sun, as if the city was wrapped in crystals.

But when they were still rushing up with a little doubt, they still rushed up and put the ladder on the city wall, a strange scene appeared. The ladder that could have successfully boarded the city or leaned against the wall actually slipped. Before they could even get up, they were already shaking and couldn't hold it at all.

This is a big problem for the Wu army. They originally rushed to the foot of the wall with the arrows and stones above, and then planned to climb up to the death. But now that the people are still killing below, the ladder cannot hold it up, so they will be completely sent to the enemy's hands and be beaten passively.

In just a moment, hundreds of casualties were caused, which scared the others so much that they didn't care about trying, and ran back with their heads in their arms, but they still caused a lot of damage along the way. Since the beginning of the offensive and defensive battle, the Wu army has not suffered such a big loss under Changshu City.

The defenders on the city increased their momentum, and the cheers became louder and louder. Everyone felt a sense of pleasure of being proud of their great revenge. They were suppressed and beaten by the enemy before, and they had helped them to come to the city smoothly several times. They were really dangerous and had not broken the enemy so easily. All of this was thanks to the hard arrangements last night and Sun Tu's orders, which made the soldiers even more respectful of Sun Qian and treated him as a god.

Among the troops outside the city, Pang Wanchun looked at the shining city in Changshu, and his eyes also showed deep thought: "I really didn't expect that they would make such a turtle shell overnight. It seems that it will take more time for us to quickly break the city."

There were also generals next to him who didn't understand what was going on, so they asked people one after another. Pang Wanchun was afraid that they would be scared by the enemy, so he smiled and explained: "Actually, this is nothing special. That is, they took advantage of the cold weather to pour water on the outside of the city wall and made it form a thick layer of ice on the wall. This layer of ice became the armor of Changshu City. Not only did it become more and more solid and difficult to break, but it was also slippery and it was difficult to even put up a ladder. Sun Tu really had some tricks and ideas!"

As soon as this statement was spoken, all the generals present changed their colors: "What should we do? In this way, won't we be able to attack?"

"Don't worry, this is just a temporary stopgap solution. My Jiangnan land is no better than the north. There are very few days when it can make water turn into ice in such a severe cold. As long as the weather gets warmer, he will only attack without attacking it!" Pang Wanchun looked confident. After hearing what he said, the soldiers were relieved, but obviously no longer had the momentum he had before, and it was impossible to launch a decent offensive against Changshu today.

Although Pang Wanchun said this, he felt embarrassed, far from as calm and composed as he showed.

Although the winter in Jiangnan is much warmer than in the north, the weather this year is a bit evil, and it is still bit cold today. Who knows when will the weather warm? And more importantly, they can't afford to spend too much time. After all, he is not worried about the Song army in Jinling. If he had been trapped in Changshu City, Zhu Xie and others would have seized the opportunity to send troops to attack. After the Wu army was exhausted after a long battle, he might have been defeated by the Song army.

"I have to think of a way to break this trick!" When I returned to the big tent, Pang Wanchun had already made up his mind secretly.

Soon, he called some of his confidant generals and advisers to come forward and asked them about the way to defeat the enemy: "Do you have any proper way? If you drag on this, it will only make our army more passive."

"Pang Shuai, why not attack with fire? We sent troops to carry hay and burn the fire under the city wall. As long as the ice on the wall is burned, we can attack the city again."

"You can't make this idea. Song Jun is not a fool. How could he watch us go to the city to set fire? The casualties will inevitably be huge."

"Also, the efficiency of doing this is too low. How long will it take to melt the ice on the entire wall? I'm afraid it will take a whole day, but at night, as long as they pour water down, our daytime efforts will be wasted!"

The generals said everything, but they couldn't come up with a proper way, which made Pang Wanchun's brows frown even more tightly. He began to miss Jiang Shihu, who had always given him a clever plan in the past: "It would be great if Mr. Jiang was here, and he would definitely come up with the most clever way..."

"Pang Shuai, it would be much easier to use a catapult to send oil to the wall and then ignite it with a rocket.

After hearing this proposal, Pang Wanchun suddenly felt his heart: "Yes, why did I forget this move? He just thought about how to break the ice, but threw the most important point behind his mind!" Suddenly, light shone again in his eyes, and he was determined to win Changshu City!
