The canvas covering the back of the truck was untied, and a stacked machine was placed inside, because no one knew what it was.

Gong Peng doesn't have to give an order. The four mutants have moved it down from the truck and put it on the ground.

There is a small door on the side of the machine. Gong Peng goes to open the door with a key, and a control button appears inside.

After inputting the password learned in advance, the machine is started, and then it starts to expand on the ground, finally forming a metal ring with a diameter of five meters and a width of half meters.

Four mutants came forward to erect the ring, then carried it into the dug hole.

They look at captain Gong Peng, who takes out the remote control device in his backpack and nods to the four.

The four of them worked hard together to make the edge of the metal ring collapse the soil layer only 20 meters thick underground. Then they continued to push the ring down. The zombies piled up below were pressed from above, some were pushed to one side, and some were pushed down.

After putting the whole metal ring into the ground, Gong Peng quickly pressed the remote control button, and the blue lights immediately lit up around the metal ring, while inside the ring, a dense network of cross organs was formed!

"Ha ha! Fill the hole! I'm going to kill you! "

As he spoke, Gong Peng took out an enhanced version of the thermal sensor, and then ran quickly. The running route was almost the same as that of the zombie passage below.

The metal circle has the function of tracking the remote control device's suspension and flying. The energy comes from the battery. The principle of using the metal circle is to take off the force of gravity and suspend. The attack means of opening is the laser network!

This is the net laser attack weapon developed by ling'er in the past two days. Gong Peng uses the remote control device to control it to run at a constant speed along the track at a depth of four meters. Then when the zombies piled up in the track collide with the dense laser network, they are all cut into pieces, like tofu!

"Damn, this kind of weapon is really awesome. Force, if you can make a large area of laser defense network, then the zombies will never be able to get close to it?"

At that time, Gong Peng asked such a question with his superior after receiving the order to install and control the ring weapon.

The superior is very helpless. Hearing ling'er say that she can't make a large area of laser network, because the energy node can't support such a large amount of laser energy, and this kind of thing is only suitable for running in orbit, using the centripetal force of the orbit. This word is given by ling'er after translating her own concept into the earth language, which is actually different from the understanding of the earth people.

Gong Peng naturally didn't understand these, so he could only sigh with his own chief.

But now it's enough! Zombies are trapped in the orbit of five meters in diameter. As long as these laser nets move in the orbit, they can kill zombies with the fastest speed.

Gong Peng is very clear that every time he goes a few meters forward, four meters underground, the laser network has killed hundreds of zombies.

Who on earth came up with the idea of the mud horse? I guess the zombie commander opposite will be mad, right? The underground breakthrough battle he worked hard to arrange has now become a big joke.

Then, in the whole coalition camp, there are 200 changers like Gong Peng controlling the laser ring to move in the tunnel.

Their goal is very simple, that is to kill all the zombies! No one left!

The night is a little quiet, and Yahoo's position is now ready like other positions.

Dong Junwei and Li Ziyuan, two commanders of the coalition forces, have issued the notice of joint operations. The most forward position will be used as a fixed blocking point to build power grid fortifications.

The Central Plains area is dominated by mecha troops to protect the zombie cleaning operation of laser circle and meet the challenge of flying zombies.

The rear is now Dong Junwei's joint command. The mutants are already gathering and will take the form of scattered operations. Once the flying zombies arrive, what they have to do is to disperse and attract them, and then eliminate them one by one.

The bad news is that intelligence from the front says that the number of flying zombies may exceed 500000, overwhelming.

The good news is that the chairman has issued an order of reinforcement at the front of the sword. Guo Sihai, his father Guo Jingda, is the commander of the third coalition, and 100000 people are moving here.

At last, Western Tibet had the courage to fight with the northern zombie forces and the two religions in Hebei plain.

This battle is different from the battle of crying blood.

At that time, the human army was completely invaded by zombies, so it could not form an effective position defense, and the additional troops could not use long-range or air weapons to support, so the battle of blood crying was doomed to be a war that would not win even if the zombies were beaten back from the beginning.

Then the Hebei plain campaign is totally different.

Because Qin An's discovery made the enemy's plot a complete failure, and human beings could advance and retreat with favorable support from the rear.

What's more, ling'er didn't regard himself as an earthman when he was in Tibet, so he didn't devote himself to making all kinds of high-tech weapons.However, since she was XX by Qin'an, she finally understood her current role, so the invention and creation in xuanjian city are endless.

If it wasn't for the limited resources, if it wasn't for the weakness of human basic science and technology, she couldn't invent a super robot to fly out and kill all the zombies.

Eleven members of qiujinse squadron gathered together and hid in the circular mobile fortress in the southeast corner of the position.

Mobile fortress is another necessary magic in the last March, which is the favorite of ordinary soldiers.

In fact, it doesn't have much scientific and technological content. It's an inverted semicircle iron pot with a base. Of course, the top is flat, and the bottom is round. It has a diameter of four meters and a height of three meters. It has an iron door opened at the top and a shooting hole on the side wall. It comes by air with the marching troops. It's easy to install. It can be directly buckled on the ground. There is an iron bar in the center, two meters deep into the ground Fix it. If trapped, the iron bar will be ejected from the ground and then raised to five meters at the top. Then there is an iron ring with a radius of one meter on the top of the iron bar. When the helicopter comes, it can put down the hook and pull it away. It can be regarded as advancing or retreating.

In the mobile fortress where qiujinse eleven people live, there are several fluorescent balls that can emit low light on the ground. This is the lighting equipment, which does not need energy.

Qiu Jinse was a little melancholy at this time, because the conversation of her ten team members made her feel like she was in a dream.

"Ah, this time they were enraged. Flying zombies are the most difficult to deal with. When I was in the South China Sea, the most common enemies I faced were flying zombies and sea animals." Guo Sihai leaned against the inside of the mobile fortress, and his face was a little worried.
