Early the next morning, Liu Yifeng got up early, he didn't wake anyone up, and set off for the depression where the Qiqi cannon was placed.

"System, is everything ready?"

"Master, everything is ready, you can go and check, in addition, master, I want to remind you that the Qiqi cannon is very powerful, and the muzzle of the cannon must be aimed, otherwise it will be ruined if it hits the city."

"Got it, I'll take notice."

Of course, Liu Yifeng understands this truth, but he doesn't understand why the system suddenly said this, maybe Liu Yifeng forgot the system's ability to predict the future.

Liu Yifeng then returned to the garrison and asked the soldiers to be fully armed and ready to fight.

The war was about to break out, and the Japanese on the city wall were strafing the machine guns of the national army, and the national army under the city was not to be outdone, aiming at the heads of the Japanese on the city wall. Seeing that the enemy was tired, Liu Yifeng ordered the artillery to open fire on the city wall.

The Qiqi cannon got its name because of the deafening sound of cannon fire and its great lethality, and after a few loud bangs, a hole was blasted open at the foot of the strong wall of the Japanese Kou. The bricks at the foot of the city wall were torn apart by the shells, and soon a hole collapsed, and the Japanese invaded at this moment, and once the national army attacked, the Japanese would die and have no place to be buried.

"Hold on! Come on, people, hold there! ”

The commander of the pirates in the city shouted at the warriors in the city, and the pirates under the city rushed forward. At the same time, Liu Yifeng ordered the independent regiment and the front-line troops to attack the Japanese from two positions, the gate and the gap, respectively.

"Brother Liu, there are two machine guns in the city, quickly send someone to kill them, many of our people have been killed by them."

Wang Lang shouted at Liu Yifeng.

Liu Yifeng looked up, and sure enough, there were two very hidden machine gun muzzles on the city wall, but to be precise, they were not two, but a row. Seeing that the situation was not good, the Japanese immediately sent people to cut out a row of small openings from the inside of the city wall and shoot them with machine guns outside. It was precisely because of these machine guns that many soldiers of the national army fell in pools of blood.

"Pass my orders, and all the artillery will be aimed at the row of openings on the city wall!"

But Liu Yifeng never expected that a poor cannonball entered the city with one shot because the angle was not adjusted well.

Suddenly, the people of the city exploded, and many people watched a blinding cannonball rush towards them. After a loud bang, a deep and large crater appeared in the streets of the town, but fortunately, the people in the city learned that the national army was attacking the city, and they scattered and fled for their lives, so that no casualties appeared.

When Liu Yifeng saw the cannonball cross the city wall and disappear from view, he sat on the ground with his buttocks, and he understood that he was in trouble. It wasn't a cannon he fired, but it was an order he gave and he understood what that meant. But now the arrow is ready to be fired, and if the siege is abandoned because of this one shell, it is obviously impossible.

Wang Lang hurriedly ordered all the artillery to cease fire and rushed to the entrance of the cave with some people. Liu Yifeng only felt dizzy in his head at this time, the picture in front of him began to blur gradually, his mouth was dry, and finally he fainted directly. When political commissar Wang Gang saw that Liu Yifeng was fainted, he immediately informed Li Xin that they would send Liu Yifeng back to the headquarters for treatment, leaving Zhu Jianguo, the deputy head of the regiment, to command the battle.

Zhang Mazi saw that the gap in the city had been breached, but the national army had not broken through yet, so he knew that it must be the Japanese who blocked them outside the city. At this time, he took a group of people with daggers in their hands and quietly walked into the defense of the Japanese invaders.

Zhang Mazi was skillful, and when he went up, he turned out to be two soldiers who were machine gun bullets, and he looked around and found that there were three layers of structure in the city wall of the devil, and most of the bottom half was the foundation, and only two or three rooms were like guard rooms; The second floor is a space on the first floor, and there are now a lot of pirates transporting ammunition to the second floor, and it is clear that there are a lot of machine gunners there; On the third floor, there are some command rooms, where many young people command the Japanese invaders; Finally, there was the city wall, where more Japanese were concentrated, blocking the national army.

Zhang Mazi didn't stop doing anything, and led the brothers in the rear to kill from the first floor.

There were only a few wounded soldiers in the guard room on the first floor to recuperate, and Zhang Mazi went in with a few knives, and after giving the results to all the wounded soldiers here, he rushed to the second floor.

As soon as he reached the second floor, he saw a lot of pirates using chisels to cut through the walls, and in some places where they had already been chiseled, several groups of machine gunners were already firing out of the city. Zhang Mazi and the brothers behind him took out their guns and fired continuously at the Japanese here.

The Japanese soon found out that Zhang Mazi and them were in Xi'an, so they no longer used machine guns, and replaced them with pistols to fight Zhang Mazi. A close-quarters pistol battle began on the second floor, with considerable losses on both sides. Zhang Mazi saw that it was not a way to go on like this, otherwise the group of people behind him would be consumed before he reached the third floor.

Zhang Mazi saw the opportunity, flipped over to a machine gun, and used the fastest speed to pile up several corpses of the Japanese into a small corpse wall. Since both sides used pistols, and the pistols did not have much lethality, they could not penetrate the corpse wall at all. Zhang Mazi neatly filled the machine gun bullets, set up the machine gun and began to strafe the Japanese on the second floor.

Because Zhang Mazi's vitality was too strong, the widow was quickly driven to the third floor. This also created an opportunity for the Nationalist troops outside the city, and when they saw that the machine guns in the walls of the Japanese invaders had stopped firing, they swarmed up, and the forward troops quickly surrounded the walls of the Japanese invaders, and they clamped the ladders and prepared to climb the walls. On the other side, the Separate Regiment also rushed to the gap and killed it.

Zhang Mazi asked the brothers to take a machine gun and kill them on the third floor. And on the third floor, there was originally a group of commanders, who had any heavy weapons in their hands, and when they saw the people on the second floor running frantically towards the third floor, and there was a dense strafing sound in the room on the second floor, they knew that the second floor had missed, and everyone ran to the top floor.

Zhang Mazi and the others came to the third floor smoothly, and only the top floor of the city wall was left before success, and they were even more arrogant, holding machine guns to the top floor.

Seeing that the general situation was gone, many of them jumped off the castle tower to make their lives clear. The Japanese under the city walls were all wiped out by the independent regiment and the front-line troops who broke through the city gates, and it was another great victory.

Liu Yifeng's side was sent to the medical department due to fainting, and Jiang Yao immediately rushed to the medical department of the division headquarters after learning the news. And Liu Yifeng has been playing the scene of the cannonball crashing into the city wall over and over again in his mind, and he understands the consequences of the cannonball, if the cannonball happens to fall in the crowd, it must be a river of blood and a loss of life. He felt that he would never wake up, and even if he did, he would forever fall into the abyss of self-blame. Jiang Yao quickly rushed to the division headquarters, and when he saw Liu Yifeng who was unconscious, tears welled up in his eyes all of a sudden.
