In the next two days, the coalition forces did not continue to attack. Obviously, before they came up with a way to crack the city head, they were unwilling to waste their troops because of this, which also gave Jiang Cheng a precious buffer period.

Under the command of Bai Zhirou and others, the craftsmen in the city quickly repaired the city wall, stirred mud and water into the cracks caused by the siege cannons.

According to the calculation results of Huowei and others, the siege cannon caused great damage to the city wall, and even damages the foundation. Even if it does not encounter any further attack, the weight of the city will continue to increase the loss, pour mud and water into ice. With the help of the cold weather today, the mud and water condense into ice in the cracks. However, this method only slows down the time when the city wall collapses. If you want to repair it, you can only push down and rebuild it. But now, obviously there is no time for them to do such a huge siege. If you really dare to push down and rebuild it, the enemy on the opposite side will come immediately.

Jiang Cheng has been in the military camp these two days, eating and living with these soldiers, exploring the method of leading soldiers. He was originally tough, but once he decided to do something, he would devote all his energy to complete it. In the past two days, he has learned a lot of military tactics and has also gained some understanding of these generals in the military camp.

On the third day, Jiang Cheng was discussing the formation with several generals when he suddenly heard the familiar sound of trumpets coming from outside the city. His face changed and he stood up one after another.

"Mr. Jiang, the enemy's return this time, is it because there is a way to deal with those institutions of Mr. Jiang Cheng?" A general looked at Jiang Cheng with a ugly expression.

"Impossible?" Another general frowned and said, "Mr. Jiang's city guarding organs are irritated when I see them. How can those ignorant small countries break down?"

"There is no absolute thing in this world. Let's take a look first!" Jiang Cheng shook his head, but his heart was a little heavy. If his mechanism was really broken, Zhaowu City, which was already shaky, would probably not be able to support it for long.

Soon, under the leadership of Jiang Cheng, a group of generals returned to the team and quickly walked up to the city wall according to the previous arrangement. Bai Zhirou and others were already waiting on the city wall. After two days, the city wall's defense system had been improved by them. Not only did they complete the city guarding mechanisms made by Jiang Cheng, but they even made more than a dozen launchers that launched archery clusters.

Although the mechanical crossbows in the city can also fire crossbow arrows, there are not many such spear-like crossbow arrows, and they are also laborious to fill. They are only suitable for deterrence and are not suitable for continuous use. Although these newly made launchers have a range and power that are far less powerful than mechanical crossbows, their advantages are that they are fast filling and have a high firing rate. The arrow clusters used are just ordinary arrow clusters. Especially in this condescending situation, they can greatly alleviate the shortcomings of insufficient archers defending the city and the inability to suppress the enemy.

"Good job!" Jiang Cheng carefully studied a launcher and smiled at the senior brothers.

"Don't worry, younger brother, with these things, this time, these coalition forces will definitely be called for no return!" Although Huo Wei looked tired, he couldn't help but say excitedly.

As he spoke, the enemy's army had slowly begun to move towards this side.

"Arrowman ready!" Jiang Cheng did not notice any siege objects the other party brought. He felt relieved a little, slowly raised his right arm, estimating the distance between the enemy's army from the city wall in his heart. After the opponent's large army entered the best range, his right arm raised high suddenly waved: "Shoot the arrow!"

The arrow clusters of the two armies converged in the air, and the thin arrow array shot out from the city was quickly covered by the dense rain of arrows from the enemy. The shield stepped forward and covered the few soldiers with a large shield. The launchers at the city began to show their power. After the cold arrow clusters accelerated by the launchers, they shot out quickly and sank into the vast sea of ​​people.

Although the range is not far, it has extremely strong penetration within the range. Even with the protection of shields, it can still shoot the enemy's shields through, and the enemy's large numbers begin to fall to the ground. This time, Zhaowu City's counterattack obviously made these coalition soldiers unable to rub their hands. The effect of more than a dozen launchers is much stronger than that of archers.

On the top of the city, the disciples and several generals of the Mathematical Art Academy showed excited expressions, as if they saw hope of defeating the enemy.

"What are they carrying around their waists?" Jiang Cheng's attention was on the jars on the waists of the coalition soldiers. The jars were not big, but there were more than a dozen hanging around each of them, which looked quite strange.

The others were also puzzled, but they didn't care. After all, in this case, they did not think that the enemy could have any new tricks.

But the next moment, Jiang Cheng saw that he rushed to the city about fifty steps, a coalition soldier took out the jar hanging around his waist. The jar was hooked with ropes. The soldiers swung the jar vigorously with ropes, and then threw the jar towards the city wall with all their might.

"Smack sex~"

The dense jars, like raindrops, were unable to block them. Some of them smashed on the city wall and shattered. The inside was filled with sticky liquid and flowed down the city wall. More of them fell on the city wall and exploded in all directions. A pungent and unpleasant smell instantly spread across the city wall.

"It's tincture!" A general frowned and touched the sticky liquid on his armor and said, "What do they want to do!"

Jiang Cheng's face changed and he said sternly: "Quick, retreat from the city and order all soldiers to exit the city wall immediately!"

Before the other generals could react, they saw rows of archers under the city, under the protection of shields, rows of archers exposed, and clusters of arrows that had been ignited with tinder oil were pointed at the top of the city. With the general's order, rows of rockets soared into the air and watched the bottom of the city fall.

At this moment, without Jiang Cheng's order, everyone had already understood what was going on. The soldiers of Wu Rui Camp began to retreat to the city frantically. Some generals and officials relied on their cultivation to directly lead the city from the top of the city.

"Boom~" The moment the arrows fell on the city wall, the flames swept across the entire city wall in an instant, and many soldiers of Wurui Camp who had no time to retreat were swallowed by the flames in an instant.

Jiang Cheng hugged Bai Zhirou, who was still in a daze, and snatched his toes into the air and landed on the top of a city. He looked down at the city wall that had turned into a sea of ​​fire in an instant, and there was still a soldier who had no time to withdraw and was constantly rolling in the sea of ​​fire. His heart was a little heavy.

Both him and Bai Zhirou were stained with a lot of tincture oil. She obviously couldn't continue to stay on the city wall. She immediately pulled her feet a little, then slowly fell towards the city.

Looking at the burning city wall, Jiang Cheng and the soldiers who survived by chance felt heavy in their hearts. Once the city wall was lost, the enemy would be able to move unimpeded. The city guards that were built overnight were all made of wood, and at this moment they probably had already turned into ashes.

"Sir, what should I do now?" A general looked at Jiang Cheng, with a little pain in his voice.
