Alexander said: "It seems that this cannon does not serve any effect. We are all happy, and now the problem is back to the starting point. Should we withdraw or use our lives to conquer this strong city?"

Everyone lowered their heads and said nothing. At this time, soldiers picked up the explosive barrels and piled them in a mess not far from the generals. Zhao Yun put his hands on his chest and paced back and forth with a frown. His eyes fell on the barrels inadvertently, and he was stunned. Then he slapped his thigh and shouted: "I have it! There is a way."

The loud voice scared everyone. Ma Chao asked anxiously: "Zilong, what good idea have you come up with?" Zhao Yun did not answer him, but instead called the captain of the artillery team, pointed to the blown barrels and said: "Can this gunpowder have such great power in any closed environment?"

The commander replied: "The general is right. The artillery was originally used to collapse the shells by using this principle. In a relatively closed environment, the impact of the gunpowder explosion is limited by the constraints of the surrounding gun barrels. They can only use all the force on the shells, which will cause the shells to be fired out of the barrels. If the barrels are of poor quality and cannot withstand this pressure, the entire barrel will explode, which is what we commonly call the explosion chamber."

Zhao Yun immediately said: "In this way, if enough gunpowder is placed into a section of the tunnel and ignite it, it can also destroy the tunnel and even overturn the buildings above the tunnel?"

The commander nodded solemnly and said, "Of course it is possible. In fact, our secret base of cannon casting was built on an iron ore. The iron ore cave was mined by gunpowder."

Zhao Yun slapped Ma Chao on the shoulder and said, "This is the right way, we can defeat Byzantium today!"

Most of the generals suddenly realized what Zhao Yun meant. Only a few who were unaware of his ideas did not understand Zhao Yun's meaning.

Alexander said: "It just so happened that our tunnel had been dug under the Byzantine walls. It seems that our efforts have not been in vain for these days. Without hesitation, we can do it now."

Zhao Yun immediately set up the arrangement, but he still politely declined the idea of ​​Alexander sending people to help. He did not even send anyone outside the artillery team in the Liang army to do these things, but the artillery commander dispatched people to transport gunpowder bags into the tunnel.

This has made these artillery soldiers suffer. They usually do not have the training to drill holes and transport objects. They carry large baskets of gunpowder and move forward in a tunnel that only needs to kneel down to crawl. Moreover, in order to ensure oxygen, too many people cannot enter at one time, and of course they cannot ignite the fire and can only move forward in the dark.

Five hours passed, and the soldiers in the artillery team who were responsible for carrying gunpowder were exhausted. At this time, at the end of the tunnel, a section of space that had been long for several battles had been filled with gunpowder. This place was directly under the wall of Byzantine City. Liang Jun used a hemp rope full of naphtha as a fire twist, spreading from the pile of gunpowder at the end of the tunnel to the entrance of the cave.

After everything was ready, it was already dark. However, the Liangluo coalition's military formation was still on guard and advanced nearly a hundred battles. However, the cavalry was still in their original place, and the war horses were filled with cotton and other objects, so that they would not be frightened by the huge explosion.

A Liang army soldier trotted to Zhao Yun and reported, "Report to General, everything is ready."

Zhao Yun said without any hesitation: "Immediate the fire!"

The fuse was then ignited, and the flames immediately followed the fuse and burned into the tunnel. With the generals' shouts in the military formation, the soldiers all lay on the ground and blocked their ears with their hands. In fact, these generals didn't know why they were lying on the ground, but the captain of the artillery team told them to do so.

The commander also knew how powerful these gunpowders were. To be on the safe side, the military formations and other places outside the city walls were warned, and it was recommended that the soldiers all lay on the ground.

Time passed in seconds, but there was still no movement. Zhao Yun, Ma Chao, Alexander and others who had covered their ears began to stir up their hearts, thinking that the action would not be done well and then failed. Then their blocked ears still heard a loud bang. The horses whose ears were blocked stood up in shock and stood up their front hooves.

At the same time, everyone felt the earth tremble violently, as if it was encountered a medium-sized earthquake. In the night, they saw the dark city wall in front of them arching upwards, and then quickly collapsed. The entire eastern city wall of Byzantium collapsed like this, and thousands of defenders on the city wall were buried in the ruins in an instant.

After a long time, the coalition soldiers who were lying on the ground were stunned to react. Ma Chao first jumped up, jumped on the mount that had just recovered from calmness, and then pointed the rifle in his hand into the air and said, "Kill!". Then more than 2,000 infantry and cavalry in his army rushed forward. However, the cavalry did not rush forward, but the infantry with long wooden boards on the front, and their duty was to walk on the road for subsequent soldiers on the ruins.

When Ma Chao led them to the ruins, his nose was filled with smoke and dust, and the choking soldiers coughed involuntarily. However, there was no sign of life on the ruins except for the groans of the Roman wounded soldiers pressing against the ruins. The Liang army soldiers were not vague and solved the pain of these wounded soldiers with one knife. Then, these Liang army soldiers sorted out the obstacles on the ruins while laying wooden boards. Soon, a road with a wide range of battles was paved.

When the first batch of Liang army infantry rushed into the city, they still encountered no obstacles. It seemed that most of the defenders were buried under the ruins. When they rushed to the government offices of Byzantine City, they were intercepted by a cavalry of two or three hundred cavalry.

These defending cavalry and their mounts were frightened by the violent explosion and "earthquake" just now. Therefore, their horses were running slowly and weak. When they rushed to the front of the Liang army crowd, they were killed and injured by the javelins that hit like a sudden rain. The remaining war cavalry fled in panic.

Ma Chao rushed to the front with one horse, followed by four or five hundred heavy iron cavalry behind him. They passed through the city like a whirlwind and rushed to the west gate. At this time, a small number of defenders on the west wall had gathered in front of the west gate, and they were ready to shoot javelins.

Ma Chao had excellent eyesight and could see these clearly. He tied the reins and turned the horse into the narrow street next to him. The cavalry team behind him also flocked into it.

When the defenders saw that the target was not coming, they were about to relax a little, but found that another group of Liang army infantry came from behind.
