"Come on, school gun, get ready to shoot. Those bastards and monsters are coming. Whether the people in our city can live depends on us. Come on!"

All kinds of roars sounded in the city wall. On the thick city wall of Chengdu fortress, the shooting ports were opened, and the dense shooting ports appeared directly from the upper part of the city wall.

Then the muzzle of each gun was extended, and the medium and long-range firepower was covered by Artillery Forces. The short-range firepower coverage mainly depended on various modified small-diameter machine guns and rapid fire guns. The ordinary heavy machine gun firepower was no longer enough to support the need to guard the fortress.

The reconnaissance troops sent back the approximate coordinates of the monster, and the firing angles of different forts were immediately adjusted. Soon, orange shells were stuffed into all kinds of cannons.

"Fire!"

A roar sounded, and then the roaring artillery submerged everything. This time, more than half of the guns in Chengdu fortress were fired. The power of nearly a thousand guns at the same time made the whole city wall tremble slightly.

"Something happened, something really happened!"

A man who was eating tofu noodles on the street didn't care when he heard the harsh alarm, because in the past, Chengdu also conducted exercises, and the alarm would sound during the exercise. Ordinary people can't tell the difference between the alarm sound.

"Pa!"

The bowl in his hand fell to the ground, and all the steaming tofu noodles were scattered on the ground. The man ran frantically to his home without looking back.

In the barber shop on the street, a man with half his hair shaved ran out in a panic wrapped in a white shaving cloth. The whole street was in chaos, vehicles ran rampant, pedestrians ran everywhere, and everyone's face was full of fear.

Chengdu fortress is completely chaotic, but now no one can take care of these things. It makes sense for people to live. If people die, what's the meaning of these things?

Just half an hour later, the streets of Chengdu were in a mess, and most people hid back to their homes with doors and windows closed.

If the wall is really broken, it makes little sense. Most people understand this, but it can still bring them a sense of security.

The garrison also wants them to hide in their own homes, which can save the garrison a lot of energy.

Li muzao has come down from the city wall and returned to the East District Public Security Branch. Monsters attack the city. The public security team also has a lot to do. They not only want to maintain public security in Chengdu and prevent people from making trouble, but also establish defense. The public security team is the last air defense front in Chengdu.

"Chief, monster, is the monster really coming?" As soon as Li Mu returned to the public security branch, all the public security officers of the branch looked at him. Luo Fusheng asked nervously.

"The monsters of Heifeng mountain and Wanyao cave have come out!" Li Mu paused for a moment, then said in a deep voice, "this time it should be pouring out, but the black snake king of the black dragon pond is dead, and other demon snakes have been badly hurt. There won't be too many demon snakes in the black dragon pond!"

The Public Security Bureau was quiet at first, and then heated discussion immediately. Some public security officers even stood up quickly and hurriedly wanted to leave the Public Security Bureau and go home.

"Be quiet, stop!" Li Mu shouted, "what's the point of going home now? Once Chengdu cannot hold, everyone will die! "

"The security team has the task of the security team. Now I organize the four sub bureaus into four joint defense teams. The joint defense team starts to deploy according to the instructions above the emergency order!"

Chengdu was not the first time to face the situation of ten thousand demons besieging the city. It also made targeted deployment for this emergency. Soon, Li Mu took out the defense map, and the order was immediately passed on.

"Open the armory!"

Li Mu quickly gave an order, and then went directly to the underground armory of the branch with the Quartermaster. He took out a key, and the Quartermaster took out a key. Then he opened the codebook, found the password according to the instructions sent by the garrison, and opened the heavy door of the armory.

In the armory, there are at least hundreds of rapid fire guns and anti-aircraft machine guns. Every public security bureau has these weapons, but these heavy firepower weapons can be used only in wartime.

There are hundreds of air fire points in each district of Chengdu. These fire points are usually not used. The air defense fire on the city wall is enough to deal with the attacks of various bird demons, but it is not enough to rely on only one defense line when ten thousand demons besiege the city, so the Sheriff needs to build a second defense line at the high point of the ground.

"Hurry up, hurry up!"

Li Mu urged loudly. The young sheriffs quickly removed weapons from the armory. Outside, military vehicles were waiting. Once they were loaded, these military vehicles would pull these air-to-air weapons to the designated location to start deployment.

The public security sub bureaus in the four major urban areas are all busy. Only the General Administration of public security has no news, but now no one can care about them. There are only two or three blocks there, and there is no impact if they do not arrange an air fire network.

"Come on, come on!"

All air-to-air firepower points are arranged in advance. The sheriff only needs to install the anti-aircraft machine gun and rapid fire gun in place. Each firepower point needs at least three people, two filling and one shooting. The Sheriff of the four divisions are all scattered to these firepower points.

The garrison was mobilized, the reserve team was mobilized, the sheriff under Li Mu was mobilized, and even the students of Wudao University and monastic college were mobilized.

Ouyang sanshao hid in the airport with his bodyguard. Once the plane could take off, he would immediately flee back to the provincial capital, and Mo Xinye had disappeared.

Li Mu and the security team are desperately completing their work. On the wall, the first wave of fire coverage has been completed.

"Boom, boom, boom!"

Nearly a thousand shells fell directly, and the dense gunfire instantly submerged a large number of monsters. The earth was shaking, the smoke of gunpowder was diffuse, and the scene of blood and flesh suddenly appeared.

All the artillery units are filled with high explosive bombs. The chip killing submunition has been completely eliminated. The killing effect of Submunition on human body is amazing, but for monsters, submunition can't play enough killing effect at all.

After a round of gunfire coverage, the smoke gradually dispersed, and the scene after the gunfire attack appeared on the large screen of the command room. Many monsters have indeed died under this round of fire attack.

However, most of these killed monsters are half monsters without products, and some beast level inferior monsters, pig monsters and iron backed wolves, which are beast level middle-grade monsters, have also been killed. However, beast level middle-grade monsters and above have not been much impressed at all, at most they have been slightly injured.

Even iron backed wolves and pig monsters, which are middle-class monsters at animal level, will not die if they are not directly hit by shells. Even if shells fall on them, they will not die.

"Even if the formula of the bomb is improved, the power of the artillery is still insufficient!" Seeing this scene, Luo Zhan's heart sank. As expected, gunpowder weapons have become more and more unable to support the situation. I don't know whether the strategic weapons developed in Shangjing can change the war results.

After the first round of fire coverage, the second round of fire coverage appeared immediately after ten seconds, and dense shells fell like raindrops.

Round after round of shells fell, and more and more monsters were killed as they grew older, but the dark river composed of monsters could not be stopped, and they still pushed rapidly towards Chengdu.

After more than a dozen rounds of artillery coverage, some powerful monsters began to be killed. Some flying red tigers were bombarded by artillery, and their injuries continued to stack. Slowly, some fell down. However, these army level monsters were reduced too slowly, and the artillery could not effectively kill this level of monsters.

But even if the power of the artillery is not strong enough, the artillery still does not stop. The artillery forces are doing their best to expand their achievements, because once those monsters come under the city wall, the artillery forces are basically useless.

The distance was so close that the artillery had no firing angle.

Under the eastern city wall, facing the roar of artillery, the special team finally arrived, but situ Yun looked up and saw the dense gun tubes on the city wall spewing fire snakes, but he was not in the least happy mood. The artillery troops fired with all their strength, which can only show that the situation is too bad now.

"Into the city, come on!"

"The gate will be sealed soon!"

The city gate officer quickly opened the side door and shouted with all his strength. There are two main city gates in Chengdu, one weighing 150 tons and the other weighing 500 tons. Once the inner metal gate is put down, the city gate will be locked immediately. Without special decryption procedures, the gate can no longer be opened.

This is to prevent someone from accidentally touching and opening the city gate at the most critical time of guarding the city, or those people cooperate inside and outside and open the door at the critical moment.

"Come on, get into town now, come on!"

Situ Yun didn't know where the demons and beasts in front had arrived, but they had to enter the city as soon as possible, because it took half an hour to put down and lock the 500 ton metal door.

The special team quickly entered the city. Then, regardless of repair, they immediately boarded the city wall and entered their combat position. The special team also had their combat mission when the monster besieged the city.

As soon as the special team entered the city, the 500 ton metal explosion-proof door immediately began to decline slowly. The hydraulic press operated at full power and slowly put the door down.

"Colonel Li, here we are. Half of the teachers from Chengdu first Wudao university are here. We are ordered to listen to you!"

In the urban area, Mo Lingyu and Wu Kun rushed over with hundreds of Chengdu first Wudao University. These teachers were ordered to follow Li Mu's command, and the remaining teachers stayed in the school. Once necessary, they would also take the students of the school to climb the city wall and fight against monsters.

"You're just in time. I need some patrols to check some important places!" When Li Mu saw Mo Lingyu and Wu Kun, his eyes brightened and he said immediately.
