The Mongolian army left the camp two miles outside Changshu City and surrounded the city. In order to prevent the Song army in the city from raiding, they dug trenches in front of the camp, arranged trenches and horse-reviated horses, and lit bonfires. In fact, who could see that this line of defense was very simple, the trenches were only two feet deep and three feet wide, so even people could jump past the trenches. The sparse trenches and horse-reviated horses were probably not even able to stop the pigs.

Of course, this was not the carelessness or laziness of the Mongolian Yuan, but was deliberately done. What they wanted was the food and military funds stored in the city, not the city, so they wanted the Song army to break through! Today, the Mongolian army used almost all the means they could use, and the bounty increased again and again, but it still failed, and there were quite a few casualties. Therefore, I hope that the Song army would "forced" the strong pressure of siege, use the flaws on the defense line to break through and leave the city.

The time of the month was over, and the Mongolian army did not look forward to the breakthrough of the Song army. The fierce battle and the rapid movement of the whole day also made them physically and mentally exhausted. The camp had already been silent, leaving only the sentries on duty looking at the city in front of them. In the quiet night, in addition to the wind, there were also faint cry of help and howls coming from time to time. They were made by the soldiers who were seriously injured and not dead during the siege and were not too late to take back. The shrill cry made the sentries feel awe-inspiring, but as time went by, it became weaker and weaker and finally became silent.

‘Boom, boom…’ Suddenly, a few dull explosions came, just like the thunder of spring, which made the sleepy sentries feel energetic and hurriedly looked at the sound. But they saw two fire dragons rising up in the air in Yushan on the edge of the city, dragging their long tail flames, making a creepy roar, and attacking towards their camp.

"Enemy attack, enemy attack..." Sentinels everywhere noticed the abnormality and shouted to ring the alarm bell. The fire dragon flew very quickly, and plunged down after reaching the sky above the camp, making a loud bang in the camp, and a dazzling ball of fire rose. Then more fire dragons rose into the sky, illuminating this moonless night. In a blink of an eye, countless rockets fell into the North City camp and exploded fire balls!

The sudden attack from the air caused the North City camp to fall into chaos. People got out of the tent, looked up at the rockets flying all over the sky, and judged the landing point in a daze, hoping to avoid the fatal blow. But there was nowhere to hide in the empty wilderness. Those felt tents were hit and turned into countless pieces, unable to provide protection for them at all, and hiding far away seemed to be the best way. The officers also wanted to restore order, but their shouts were inaudible in the violent explosions, and they could not be organized at all, and they could only be carried away and retreated.

"Kill, kill..." The bombardment from the city lasted for about a quarter of an hour and gradually subsided. Before the Mongolian soldiers packed up their troops, a shout of killing came from the front of the camp. A group of men in black jumped up and rushed into the camp. The outposts who were still panickingly looking for a refuge fell to the ground with the banging gunshots. They rushed forward quickly, picked the corner of the Lu, moved away from the horse, and rushed into the camp.

"The enemy attacked the camp!" Someone found something wrong and shouted loudly, but the scene was chaotic at this time. It can be said that the soldiers could not find the generals, and the generals could not find the soldiers. The soldiers who spontaneously stood up to resist were not the enemy soldiers who were swarming, and were shot dead before they could fight, or were stabbed down by bayonets. The Mongolian army, who could not organize the resistance, ran faster, but as they fled, they found that the Song army attacking the camp did not chase them at all, but rushed to the stone throwing position.

When the Song army soldiers drove out the remaining enemies, they divided up a group of people and hung their backpacks on the stone thrower, even just under it, and then rushed to the next target. The explosion of "boom, boom, boom" came out again. The giant stone thrower was either blown up and turned into wood chips, or fell to the ground and ignited a fire. The kung fu was not long, hundreds of scattered fumbles had been blown up by the Song army, and the siege cars were destroyed by them. The explosion was so scattered on the ground that it was stumbled and slumped on the ground, which was unbearable.

The Mongolian army also realized at this time that they were not trying to break through or annihilate them, but the target was those stone throwing machines. When they hurriedly organized, two red lights rose from the ground and exploded in the air. The Song army immediately covered and began to retreat, and the rocket launcher was launched again at this time. The Mongolian soldiers who were trying to pursue could only retreat helplessly, watching the Song soldiers retreat calmly to the city with the help of...

Yuxi Timur soon learned that the Song army left the city and attacked at night, destroying most of the stone throwing machines and siege cars. As soon as the sky was dawn, he came to the north city to check the situation. Looking at the broken equipment all over the ground, his face became more and more gloomy, and his heart became more and more irritable. The facts verified his judgment that he did not want to believe - the Song army had no intention of giving up the city breaking through, which means that the enemy was trying to hold on to the city, and the plan to easily obtain materials from the enemy would not be so easy to achieve.

The siege equipment was destroyed, and today's siege was just a waste of troops. Yuxi Timuer was angry and ordered the monk Wanfu to beat him fifty whip and kill two centurions who were responsible for guarding the night to shock the somewhat scattered military morale. However, he had to face the facts in front of him, reconsider the siege plan and how to advance if he could not obtain supplies.

Yuxi Timuer knew that not all kinds of wood were suitable for making siege equipment, especially stone throwers were more picky. The cannon stand and casting rod needed a limited number of varieties to ensure strength and hardness, so as to avoid breaking during launch. The siege cars seemed to have less stringent requirements, but they also needed to grow for more than ten years, and were trees that had been decades long.

At present, in order to build siege equipment, the trees in several miles of surrounding areas have been cut down almost completely. If you want to obtain enough wood, you must collect them farther away, which means that more manpower and material resources and the time they need most will not be mentioned in a short period of time. But time has now become the most urgent need of Yuxi Timur. The key to his plan is to invade Jiangnan when the enemy's troops in Jiangdong are empty, seize Changshu City with lightning speed and obtain material supplies. Then, use the time difference required for the Southern Dynasty to mobilize troops to encircle and attack Yangzhou to return to aid, and quickly advance towards Lin'an, defeat the few troops left by the Southern Dynasty's capital, capture Lin'an, and force the sub-subsistence to the Southern Dynasty.

When the Song army returned to the aid army, the situation was already hopeless, so there was a lot of room for operation. But now everything deviated from their own ideas, and they lost their first battle after they crossed the south. Yuxi Timuer understood that facing a strong city with strict defense and a battle to the end, besieging the city is often the choice of most generals. They set up camp outside the city and waited for the defenders to spend all their food.

However, Yuxi Timuer could not afford to spend time and was not in the mood. Changshu City was a material reserve point set up by the Song army, which was used to support the battles of tens of thousands of Song troops in the lower reaches of the Yangtze River. The most important thing was food and weapons. It would be a long time to break the city through siege, and he really couldn't wait. On the other hand, what he wanted was the materials in the city. A city that consumed all its materials also lost the meaning of seizing the city.

In fact, there are not many methods of siege. In addition to scoring the city, there are nothing more than water attack, fire attack, and digging tunnels. The water network around Changshu is crisscrossing, and water attack should be a reliable choice. The rainy season has not yet arrived, the water level of the river is shallow, and the moat is connected with the surrounding water systems. It is also a huge project to block all waterways. In addition, the commanding height of Yushan was encircled into the city, so they can also defend it with this.

The water attack plan was quickly denied by Yuxi Timur. The fire attack seemed unreliable to think about it. First of all, you need to throw the fire into the city with a catapult, but most of the catapults were destroyed, which could not form a scale effect and be extinguished in time. Take a step back and successfully implemented the fire attack and captured the city, but if the granaries in the city were burned together, you would not be able to find a place to cry.

After thinking for a while, Yuxi Timuer and Zhao Bing thought of a piece, only digging tunnels could be feasible. However, there is also an unknown, and there is no need to worry about the technology to dig tunnels. The problem is that this strategy is not a test. If the city wall is built on hard rocks, it is impossible to dig tunnels below. If there is a moat outside the city wall, or the soil under the ground is soft or soaked in water, the conditions for digging tunnels are also not met.

In addition, even if the excavation conditions are ideal, the conditions of the diggers themselves are far from related to their ideals: the environment they work in is dark, humid, and full of dangers - if the soil layer above their heads suddenly collapses, the tunnels they excavated will become their own grave. Moreover, it is not easy to dig tunnels under peaceful conditions, and it is even more dangerous in the environment of war.

After all, the besieged side will block the excavator's progress at all costs. Before starting digging, when the digger tries to approach the planned excavation site, they have to find ways to avoid the other party's arrows and rain. For this reason, they also have to use the cover of equipment to move forward carefully. Even if they reach the ground, the excavator still has to face the danger of being attacked. After all, the purpose of digging tunnels is to sneak into the city, rather than digging the entire city wall. Otherwise, the project volume required is too great, and they still lack the gunpowder that the Song army has to use.

After making up his mind, Yuxi Timuer personally inspected the terrain and chose the excavation location while asking people to build equipment. Xicheng was built on the mountain. If you want to dig the tunnel from now on, it is equivalent to passing through the mountain. Even if it is a mountain of earth, you don’t know that it will take until the year of the Monkey and Horses to complete it. The East City is similar to Qinhu Lake and Qinchuan Canal. If you don’t dig through the water layer, you will be reversed. On the south side, Shanghu Lake and Kuncheng Lake will raise the groundwater level, which is not conducive to excavation. Therefore, only the North City is more suitable.
