The city wall more than ten kilometers long in the East is burning almost everywhere. Fierce exchanges of fire appear everywhere, including the bodies of iron backed wolves, flying red tigers, shadow blood cats, pigs, monsters and human bodies. Dense corpses can be seen inside and outside the city wall in the East.

Countless monsters piled up under the city wall. Half of the city wall was covered with monsters. From a distance, those monsters looked like ants trying to climb over the city wall.

On the city wall, with the snake demon killed, the great ape king did not open the situation. The situation suddenly fell into a stalemate. The monster could not climb the city wall, so it could not destroy the air fire point above the city wall. The air fire point was not destroyed, and the bat demon could not easily enter the city.

On the city wall, the great ape King gasped and stared at Li Mu and headmaster Jin. The blood in his eyes was more and more prosperous, and his reason was less and less. The monster was going crazy.

Li Mu took a deep breath, exhaled with a faint smell of blood mist, and forcibly pressed down the injury on his body. Although the tiger devil immortal body was strong, it was not perfect after all. With the strength of the great ape king, Li Mu had suffered a lot of internal injuries against its attacks so many times.

However, the injury is not too serious and is far from unbearable. Li Mu estimates that he should have no problem resisting the attack of the great ape King more than a dozen times.

With headmaster Jin nearby, they should be able to lose both sides with the great ape king in these dozen attacks. Li Mu used his biggest hand to kill the black snake king today, otherwise the battle would not be so difficult.

"Be careful, this monster is going to work hard!"

President Jin warned Li Mu warily that Li Mu was young. He was afraid that Li Mu was not experienced enough and was seriously injured at the moment. If Li Mu was injured soon, the situation would turn sharply.

"I know. I'll find a chance to drive it down later!" Li Mu said in a deep voice.

President Jin nodded slightly. Now one of his arms is broken. At most, he can only play 50% or 60% of his strength. With Li Mu staring at him, he can still play some role. But if Li Mu can't stand it, he can't do it.

After resisting the attack of the great ape King more than ten times, president Jin also knew that Li Mu must have been hurt. Now the battle has reached the most dangerous time, it depends on whether they can't carry it first or the great ape king can't carry it first.

Li Mu and headmaster Jin were ready to fight for their lives, but at this time, a deep strange beep sounded fiercely. Li Mu and headmaster Jin were stunned, and their faces changed and they were on alert immediately.

"Be careful, it may be the bat demon king!" Principal Jin said nervously.

Li Mu was also worried. He was in poor condition and Luo Zhan was injured. If the bat demon king chose to attack at this time, he would really have to fight his life.

"Roar!"

But when Li Mu and principal Jin were on alert, the great ape Wang Meng raised his hair, gave a unwilling roar, beat his chest several times, and then jumped directly from the 100 meter high wall and disappeared into the monster herd.

The numerous monsters seemed to get some signal and quickly retreated like the tide. In the twinkling of an eye, they were out of the range where the heavy machine gun position could attack intensively. Obviously, these monsters obeyed some orders and just stayed on the edge of the firing range of the Artillery Force.

If they retreat further, they will enter the shortest range of the artillery, and if they advance further, they will enter the effective range of the heavy machine gun. Although the bullets of the heavy machine gun can hit at this distance, at that distance, the power and accuracy of the heavy machine gun have become dispensable.

In the sky, the dense bat demons did not try to continue the dive attack. One bat demon rose into the sky. In the twinkling of an eye, it was like a dark cloud floating away, out of the range shrouded by anti-aircraft machine guns and rapid fire guns.

The monster retreated?

These monsters attacked suddenly and retreated inexplicably. Li Mu swallowed three small gold pills directly, chewed them up and swallowed them directly. Then he went to the edge of the city wall and looked under the city wall.

The huge snake demon body under the city wall is still there, just like a huge inflatable toy at the root of the wall, but only when the inflatable toy is still alive can we understand how terrible it is.

Beside the huge snake demon corpse, there are thousands of monster corpses everywhere. In such a short attack of less than two hours, the monster left tens of thousands of corpses, but the garrison also suffered heavy losses.

The soldiers of the garrison have been directly reduced by more than 8000. Many fortifications and forts have been destroyed, and the ammunition consumption is even more amazing. Fortunately, the military factory of Chengdu military can produce ordinary pills by itself. Now the military factory has started working overnight and will produce all kinds of ammunition 24 hours a day.

"Those monsters are really gone!" Headmaster Li, holding his broken arm, stood next to Li Mu, looked into the distance and said.

The monsters attacking the city have dispersed and disappeared in the towering forest outside the city. Once these monsters disappear in the forest, there is no way to take them unless they are shot by artillery in a large range.

"It won't be so simple for monsters to besiege the city. I doubt whether they have any conspiracy!" Li Mu looked at the disappearing monster and said in a deep voice.

"Although monsters are very clever, they should not be so capable if they play tricks?" Headmaster Jin said suspiciously.

He has been dealing with monsters for more than ten years. Although monsters are smarter than beasts, some are even very cunning, when it comes to conspiracy, president Jin thinks that maybe the intelligence of monsters is enough, but I'm afraid he doesn't have that idea.

"We have an old saying in China called 'its wisdom is close to the demon'. Some demon beasts are far more terrible than we thought!" Li Mu said meaningfully.

In his thirty years of memory, Li Mu has seen many frightening and intelligent monsters who can turn people around.

"I hope it's just your guess. My arm is broken. I have to treat it first. You can heal it quickly. Those monsters may make a comeback at any time!"

President Jin said something to Li Mu. Then he turned and walked slowly under the wall. His injury was not light. He must be cured as soon as possible.

When Li Mu saw president Jin leave, he turned and walked under the wall. The injury on his body was not a big problem. He took three small gold pills and recuperated. The key is not to know what these monsters want to do, but to make more preparations.

"Sir, those monsters have really retreated. The UAV has monitored that the great ape king has left near the city wall. It should not appear again in a short time!"

In the command room, the intelligence officer said excitedly.

"Send drones to Heifeng mountain and Wanyao cave!" Luo Zhan said in a deep voice.

"Yes, sir!"

In the high air, the two black spots began to accelerate to the Heifeng mountains and Wanyao cave. Soon after, the two large unmanned reconnaissance aircraft reached the predetermined position, but the pictures returned by the two unmanned reconnaissance aircraft made everyone in the command room sink.

In the pictures taken by the UAV, there are still dense monsters constantly emerging from the Heifeng mountains and Wanyao cave. After these monsters appear, they no longer rush to Chengdu, but gradually spread in all directions and slowly approach Chengdu. They spread too far away from each other, and the artillery can no longer form an effective threat to them.

"The bat demon king and the great ape king are waiting for these monsters to come. They want to win Chengdu in one go!" Luo Zhan said with a heavy heart.

"What shall we do now?" Rowe asked solemnly, "now principal Jin has broken an arm. Colonel Li may be injured, and you may also be injured. The situation has been very unfavorable to us!"

Luo Wei's heart is also heavy. Now the bat demon king may not know that Luo Zhan has been injured. Once it knows that Luo Zhan is injured and cooperates with the great ape king to attack forcibly, Chengdu will be dangerous at that time.

"Let's directly implement the Tianzi No. 1 plan. We don't have time to wait for all the array arrangements to be completed!" Luo Zhan said in a deep voice, "in addition, I'm not the only one in Rong City. I'm the strong one at the top of the master's three grades. The personal bodyguard of Ouyang San Shao is also the same. You go to him personally and ask him to do it at the critical moment!"

"You tell Ouyang sanshao that if Chengdu is broken, they will die. We must let him send people!"

Old man Liang is also a strong man at the top of the master's three grades. From his ability to hurt Luo Zhan, it can be proved that once Chengdu can't hold, Ouyang sanshao can't break through and escape under the siege of ten thousand demons. He should know this very well. If Ouyang sanshao doesn't want to die, he will send old man Liang.

After all, the monster doesn't know who he is. Once the city is broken, he will die.

"Now the array has not been arranged. Once the weapon is used, we may only have one chance to use it. The gain is not worth the loss!" Rowe hesitated.

"Don't use it now. Maybe you won't have a chance to use it in the future. Go and prepare. Don't think so much!" Luo Zhan waved and said.

"OK, I'll go to find Ouyang's group of three young people after arrangement!" Luo Wei knows that Luo Zhan is right. If people die, any weapons are useless. The weapons that can be used while people are alive are good weapons.

"Count casualties, treat the wounded, repair fortifications and replenish ammunition!" Luo Zhan watched Luo Wei leave, turned around and ordered, "burn all the corpses of monsters under the city, and the corpses of soldiers in the city. Now we don't have time to deal with these corpses slowly!"

Needless to say, the corpses of monsters outside the city can be handled directly from the city wall by using flame throwers. If the corpses of soldiers are sent to the crematorium for incineration in turn, they can be handled within a week. However, at present, internal and external troubles can only be handled specially. The garrison doesn't have so much time to deal with these corpses slowly.

If these corpses inside and outside the city are not burned and disposed of as soon as possible, it is easy to have problems. Especially in this kind of war, the corpses of monsters are easy to attract all kinds of strange things, while human corpses are easy to become ghosts, so they must be disposed of as soon as possible.

When the monster retreated, the atmosphere in Chengdu was not relaxed, but full of the tension of mountain rain.
