If only there was cement in the warehouse.

This was Sun Tu's first reaction at this time, because this was the fastest way to repair the city wall now. But unfortunately, at least so far he has not found any trace of cement in the system warehouse, and he is not an engineering student, and he does not have a recipe for cement - and even if he had, it would have been too late to make it overnight.

Now Sun Tu can only scratch his head there, he is not an immortal after all, and he really can't make the city wall repair and improve without materials. And after seeing his somewhat helpless reaction, Peng Yongzhen was even more flustered, and muttered: "How is this good?" How can this be a good ......?"

The nervousness soon spread out again, which made many soldiers around them panic, and many of them were full of despair and regret. Desperately, the city is difficult to protect, after all, the integrity of the city wall was easily entered by the rebels before, and now there is such a big hole, tomorrow's battle will inevitably be more dangerous, maybe the first battle will be broken by the rebels; What regrets is that he didn't work hard to repair the city earlier, so he has to take his life now.

Sun Tu's face became more and more solemn, once the north gate could not be defended, Changshu would inevitably be lost, so there was only one way left to break through. But in this way, even if the casualties are not large, returning to Jinling will inevitably be deliberately targeted by Zhu Mian, and the situation will become more and more difficult.

"Sun ...... Sun Chuzhi, the villain may have an idea to repair the city wall temporarily......" Someone next to him suddenly whispered, and when it reached Sun Tu's ears, he immediately lifted his spirits, and quickly turned his head to look over, but saw an ordinary-looking Qingzhou soldier lowering his gaze a little crampedly, not daring to look at him.

"Do you really have a good plan? What is your name? Sun Tu immediately grabbed his hands and asked urgently. Not only Sun Tu, but countless soldiers around him also set their eyes on this ordinary soldier, with expectations and doubts.

It's just that this made him even more nervous, and it wasn't until Sun Tu asked twice more urgently that he hesitated and said: "The villain's family was poor a few years ago, and the house was broken and couldn't be repaired, leaking water in summer and wind leaking in winter." Later, I couldn't stand the cold, so I thought of a stupid way......"

After listening to his slightly long-winded explanation, Sun Tu's eyes suddenly lit up, and before others could react, he patted the shoulder of the soldier named Qi San and praised: "You saved me all over the city this time." I'll take credit for your work, and I'll reward you again! ”

Qi Sanyi was also very excited when he heard this: "It is a blessing for the villain to be able to help Sun Chan to contribute, and I don't dare to ask for any reward." ”

And Peng Yongzhen and other generals who had already reacted on the side still had a little suspicion: "Sun Chanzhi, can this really be done?" ”

"Of course, ordinary houses can be repaired like this, and of course our city walls can too! And it works the fastest, and now that the weather is very cold, you can give it a try. ”

"But this can only last for a while...... Once the weather heats up, isn't it self-defeating? ”

"I'm just going to solve the urgent needs now, and I'll leave the rest for later. Quick, get some water, the walls must be repaired before dawn! Under the loud urging, Sun Tu's heart suddenly moved, and he said: "Not only can you use this method in the damaged parts of the city wall, but also pour water on me in other places!" ”

"Huh?" All the soldiers were a little stunned, and they didn't understand what kind of medicine he was selling in his gourd. But Sun Tu had no time to explain further to them: "Just do it, this is a military order, and it is also the most effective means for us to resist the onslaught of the opposing army!" ”

Peng Yongzhen didn't dare to disobey Sun Tu's order anymore at this time, and immediately turned around and ordered: "Don't go quickly, if you dare to be lazy again, I will severely punish you!" ”

Even their own generals said so, and others could only do so even if they had doubts. And after Sun Tu saw them acting, he also hurriedly left, and walked towards the nearest east city wall, followed by the west gate, and then the south gate......

In the first half of the night today, Sun Tu rushed around the city, and at the same time issued an order that many soldiers could not rest, asking them to get a large amount of water nearby and splash it directly on the outside of the four city walls.

So this night, the four cities of Changshu have become a big construction site, and the sound of people working hard in the city can be heard from afar, and even the Wu army outside the city has noticed the movement there, and specially sent a team to investigate the news, but was soon shot back by a burst of arrows.

And when Pang Wanchun learned this information, it was already close to dawn, but the black light and the distance were related, until this time, he didn't understand what Song Jun was tossing in the city, but a faint uneasiness rose from his heart.

It wasn't until the dawn of the day, under the urging of drums and trumpets, that the Wu army launched an offensive on the north gate of Changshu again, thinking that there were still loopholes in the north city wall, and then when they went in, the soldiers who rushed in front were surprised to find that today's Changshu city wall has changed a lot-

The city wall, which had been damaged and mottled before, and even had a large gap, had become smooth and solid, and the gap had been filled, and it was still shining brightly in the light of the rising sun, as if the city had been wrapped in crystal.

And when they had a little doubt, but still waved their troops to kill and put the ladder up to the top of the city, a strange scene appeared, the ladder that could have been successfully mounted on the city, or leaned against the wall, was actually slippery, and before anyone could go up, it was already crumbling, and it was not stable at all.

This was a big problem for Wu Jun, who originally rushed to the foot of the wall with arrows and stones from above, and then planned to risk their lives to climb up. But now that the people are killed below, the ladder can't stand up, so it will completely become sent to the enemy and passively beaten.

In just a few moments, hundreds of casualties were caused, and the others were so frightened that they couldn't bother to continue trying, and ran backwards with their heads in their hands, but they still caused a lot of damage along the way. Since the beginning of the offensive and defensive battle, the Wu army has never suffered such a big loss under the city of Changshu.

The defenders of the city were greatly imposed, and the cheers and drums became louder and louder, and everyone had a sense of pleasure in raising their eyebrows and taking revenge. They were pressed and beaten by the enemy before, and they were allowed to go to the city smoothly several times, which is really dangerous, and they have not broken the enemy so easily. And all of this is thanks to last night's hard work and Sun Tu's order, which made the soldiers respect Sun Chuzhi more and more, and they all regarded him as an immortal.

In the army outside the city, Pang Wanchun looked at the glittering Chang [Smoke and Rain Red Dust fo] familiar town in front of him, and his eyes also showed a thoughtful look: "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 break the city quickly." ”

There were also generals next to him who didn't understand what was going on, so they inquired about it. Pang Wanchun was afraid that they would be really frightened by the enemy, so he explained with a smile: "Actually, this is nothing special, that is, last night they took advantage of the cold weather to pour water on the outside of the city wall, and caused it to form a thick layer of ice on the wall. This layer of ice has become the armor of Changshu City, not only has it become more and more solid and difficult to break, but it is also slippery and hands-free, and it is difficult to even put up the ladder again, this Sun Tu really has some means and ideas! ”

As soon as these words came out, all the generals present changed color: "How is this good? In this case, won't we be able to attack it? ”

"Don't worry, this is just a temporary expedient measure, and the land south of my river is no worse than the north, and there are even fewer days when such a severe cold can splash water into ice. As long as a few days pass, when the weather gets warmer, he will only move and will not attack himself! Pang Wanchun looked determined. Hearing him say this, the soldiers felt a little relieved, but obviously they no longer had the momentum they had before, and it was impossible to launch any decent offensive against Changshu today.

Although Pang Wanchun said so, he was also embarrassed for a while, far from being as calm and calm as he appeared.

Although the winter in the south of the Yangtze River is much warmer than in the north, this year's weather is a bit evil, and it is still cold and biting today. And more importantly, they can't afford to consume too much time, after all, he is not worried about the Song army in Jinling, if he has been trapped under the city of Changshu, he is really Zhu Mian and they seized the opportunity to send troops to attack, and the Wu army is tired of soldiers and horses after a long battle, and it is really possible to lose in the hands of the Song army.

"I've got to find a way to break this trick!" When he returned to the big tent, Pang Wanchun had secretly made up his mind.

Soon, he summoned some of his henchmen and advisers to him, and asked them how to destroy the enemy: "Do you have any proper methods?" If it drags on like this, it will only make our army more and more passive. ”

"Pang Shuai, why don't you attack with fire? We sent our men and horses with hay and started a fire under the walls, and as soon as the ice on the walls was burned, we could re-attack the city. ”

"You can't make this idea, and Song Jun is not a fool, how can he watch us go to the city and set fire? The casualties will inevitably be enormous. ”

"Moreover, it is too inefficient to do this, how long does it take to melt the ice on the entire wall? I'm afraid it will take a whole day to make it, but at night, as long as they pour water down, our efforts during the day will be in vain! ”

The generals said everything they wanted, but they couldn't come up with a proper way, which made Pang Wanchun's brows furrow even tighter. He began to miss Jiang Shihu, who had always been able to give him a clever plan in the past: "If only Mr. Jiang were here, he would definitely be able to come up with the most ingenious way......"

"Pang Shuai, it's better to hit the wall with catapult fuel and then ignite it with a rocket, so it's much easier to burn the ice."

After hearing this proposal, Pang Wanchun's heart suddenly moved: "Yes, how did I forget this trick?" I only thought about how to break the ice, but I left the most important point behind! Suddenly, the light in his eyes was renewed, and he was determined to win Changshu City!
