During the march, the most feared weapon of the troops is landmines.

If the mutants swarm towards the surrounding wall, the explosion of these mines is the best defense for them.

However, Cai Ruichen did not rely on all these mines, just like those sniper weapon modules, hundreds of them were prepared on the wall, and the snipers commanded by Tang Zuwang were responsible for the use of these weapons.

With the defensive weapons above and below the walls, according to the multiple virtual world simulations conducted by the base, at least hundreds of thousands of mutants can be killed and injured.

The number of kills depends on how the mutants will attack in a cooperative way, and if it is a swarm attack, the lethality will be maximized.

However, if a small-scale attack is used, the defense of the base and the firepower will be too wasted, and the damage in a short period of time will be weakened a lot.

So, although many simulations have been carried out in the virtual world of the base, it is difficult to say what exactly will happen in reality.

Because in many virtual world simulations, the virtual mutants under the command of the base all successfully broke through the defense of the wall.

As a result, it all ended in Cai Ruichen's defensive failure, but in this failure, Cai Ruichen clearly understood the weakness of the defense.

The current mine tactics are to strengthen the killing of mutants, because after many failed simulations, they were proposed by Elle Yesel.

After the mine tactics were proposed, Cai Ruichen also conducted a simulation, which was really effective.

Although it is due to the base, the mutants are in the offensive formation. Adjustments were made quickly. It also led to a failure of the defense.

But Cai Ruichen believes. Even if the mutants in Erbil already possess extremely high intelligence, they should not have such a level of targeted command as the base.

Now, he is almost ready to fully retake Erbil, and whether it succeeds or not depends on the will of God.

On the fence, hundreds of rocket mine-laying trucks were busy, and a large number of mines were all thrown into the steppe between Erbil and the wall.

200,000 mines, just the right density, not too much and not too little. Exactly at a reasonable density, the whole city is surrounded.

However, Cai Ruichen did not rush to activate all the mines, but only asked the base to activate some of the 50,000 mines.

The first day of minelaying had just been completed, and the next day it was still on the walls, and this time a second batch of mines was delivered to the walls.

It's just that the second batch of mines was not dropped, but placed on the fence like this.

Today's show is not about these mines, but about the horror robots that are being prepared behind the walls.

The gates in the walls surrounding Erbil quickly opened, and the prepared horror robots quickly climbed out of the walls.

Then the gate of the fence was quickly closed for the first time, this time. However, there are not many scary robots that come out of the walls.

For this battle. Cai Ruichen prepared two thousand terrifying robots, and the ten terrifying robots, which were scouts, quickly rushed towards Erbil.

At a speed of 100 kilometers per hour, it soon entered the city of Erbil.

The mutants who were roaming the streets all roared quickly when the terrifying robots entered the city.

Then they all stopped wandering and ran towards the terrifying robots.

On the wall, Cai Ruichen, who saw this scene, couldn't help frowning, the reaction of these mutants seemed to be unusually intense.

Could it be that territorial consciousness is at work?

Cai Ruichen didn't know, but judging from the fact that these mutants frantically flocked to those terrifying robots, these mutants were very angry.

It's just that against these ordinary first-level mutants, the ten terrifying robots who entered the city did not shoot, after all, the machine guns on their bodies only had two hundred bullets, and their combat effectiveness was not long-lasting.

The main thing is that this time they entered Erbil, not to kill mutants, but as scouts, to see what was going on inside.

Each horror robot has a high-definition camera that transmits what it sees to the base or to a set computer.

This connection also allows the soldier to manually manipulate the actions of the terrorist robot.

At present, these ten reconnaissance horror robots are still in the eyes of everyone on the wall.

The information of the mutant transmitted by the base enters the computer chip at the core of the terrorist robot, so that the terrorist robot immediately grasps the various action data of the mutant.

It also understands all the weaknesses and characteristics of mutants, and is also able to distinguish the level information of mutants by themselves.

The ten terrifying robots that walked into the main road of the city all took the initiative to greet the hundreds of mutants surrounding them.

The strength of the first-level mutants is enough to destroy the horror robots, but the attack power of the horror robots is also enough to kill these mutants in seconds.

Faced with the surrounding mutants, after system analysis, the terrifying robot quickly jumped to the crowded abandoned vehicles on the street.

Four razor-sharp claws quickly climbed over these abandoned cars, approaching the mutants approaching on the ground.

The two sides have zero contact at close range, and the next battle is clean and neat, although the horror robot is very low, but the limbs are also very slender.

Before the mutants could get closer, their slender limbs could easily penetrate their heads.

The posture is like a spider predator, and the mutants who only have the ability to attack instinctively are not the opponents of these professional killing machines at all.

Even if they encounter a second-level mutant, the lethality of these terrifying robots is still strong.

Because they have joints in their limbs, they all have electric hydraulics that allow them to penetrate the belly armor of the tank.

Not to mention the defense of these ordinary mutants, it is completely abusive.

However, due to the large number of mutants, and the strength of the mutants are all very strong, there is also a mutant who was torn off a claw by the mutant in close proximity during the battle.

The remaining three-legged horror robots had to withdraw from the battle, and although they were still able to move, they no longer had much attack power.

After all, it takes at least three claws to support the body, and the triangular phalanx supports the body to provide strength for the other attacking claw.

Easily killing these hundreds of mutants, it was as if they had stabbed a hornet's nest, and the mutants in the entire Erbil began to be restless.

This is completely different from the previous situation of sniping mutants, probably because the terror robots invaded their territory and are now arrogantly killing people, which caused the other mutants in the city to go berserk.

However, just as they all converged towards the scene of the incident, only a staggering figure could be seen leaving the city. (To be continued.) )
