Cai Ruichen has never been naïve to think that special mutants are just the patent of mutants in Iraq.

There are seventh-level mutants under the command of Scourge, and there are also many sixth-level mutants, and the number of fifth-level mutants is even larger.

Cai Ruichen absolutely believes that in this battle, the scourge must also have its own powerful killer weapon.

Special mutants, to this day, Cai Ruichen has seen the big Roshan under the command of Qianhe, which integrates offense and defense, and also has the ability to throw, which is a balanced special mutation.

I've also seen special mutants who can drill into the ground and throw abilities, and their defense is very special, and the killing effect of thermal weapons is very poor.

I have also seen a special mutant of the defensive type, with a huge body and a shield with strong defense, which can be used as an offensive cover for regular mutants, and with strong defensive power, it can advance directly to the edge of the wall.

What worries Cai Ruichen a little is that this guy has arrested all the survivors in Iran, and he must have fought with the army of the Iranian survivors before, and he fully understands the attributes of human war weapons.

With the wisdom of jealousy, there will inevitably be a way to deal with it.

This is also what Cai Ruichen is more worried about, after all, no one knows what kind of offensive tactics this eighth-level mutant will adopt.

Judging from the current steady and steady situation, Cai Ruichen has already felt a lot of pressure from three points.

Scourge did not rush to attack at all, and he had to completely assemble all his forces to avoid adding fuel tactics, and he was able to destroy the defense of the base with his strong forces in one go.

As for the special mutants, it is an unknown that no one can imagine, after all, the special mutants are all strange and have no rules to follow.

The only thing that made Cai Ruichen feel fortunate was that all the high-level mutants under the command of Woe Ji had been killed.

And with the help of the time when the opponent's troops were gathered, Cai Ruichen also concentrated all his troops.

In the present world, Cai Ruichen only left 150,000 Red Police soldiers, and in the wasteland, the main force of the Red Police Corps has increased to 350,000.

Among the four standing divisional units among the street survivors, there are more than 400,000 troops capable of fighting.

In terms of defensive work, the original 80-meter wall has been increased to 100 meters, and the second wall has also been increased to 80 meters.

A wall with a height of 100 meters is equivalent to the height of a building of more than 30 floors, and if an ordinary human person stands under this wall, he will see a magnificent wall that goes straight into the sky.

The hundred-meter-high wall is absolutely unprecedented in the history of mankind, and if it weren't for the base wall construction model, it would be difficult for Cai Ruichen to raise the wall to such a height.

Moreover, the thickness of the first wall has reached an astonishing sixty meters, and at this width, even global transport planes can land on the wall.

All kinds of heavy equipment can also enter the city wall and directly attack the outside.

The main thing is that in the middle of this hundred-meter-high wall, there are a large number of built-in defense units.

On the edge of the wall, iron towers stand up, nearly 50 meters long, there is one 100 meters apart, and thick iron rings are set on the towers one by one.

Beneath the wall, the Gate's cannons were all clearly erected at the base of the wall, and the muzzles of the guns were facing the plain outside.

And this kind of defense is still being improved every day, and now Cai Ruichen is as if he is playing a game.

Actively defending against the computer's imminent frenzied attack.

However, Cai Ruichen, who has never liked completely passive defense, has never stopped preparing for active defense while strengthening the house on the fence.

Every day, large rows of trucks left the perimeter of the base and scattered into the plains.

These trucks are naturally self-detonating trucks, and Cai Ruichen has no intention of letting these self-detonating trucks rush into the assembled mutants now.

Instead, it was arranged in a dense formation, outside the base, on the front of the mutant attack.

Originally, Cai Ruichen planned to deploy millions of anti-infantry mines on the dense grassland, and only needed to throw the mines out, and then after the other party passed through the minefield, he activated the fuse of the mine, which could definitely bring huge lethality to the mutants.

But the attack of the mine, at most, is to kill ordinary mutants and injure those two or three. Level 4 and level mutants can't do any damage to those level 4 and level 5 mutants.

The self-detonating truck is very simple, and within the range of the explosion power, it has absolute lethality.

In order to be able to further kill and injure mutants, the Red Guard Corps also arranged a death zone that could not be seen.

Radiation Engineer, this arm has both attack and defense, can carry out anti-virus operations, and can also carry out virus deployment.

Radiators are able to unfold an area of the virus, and any creatures that enter this area will be killed by the virus.

Although mutants are immune to most viruses, their bodies do not age, and they do not get sick, but the radiation sappers still have the means to deal with them.

The Red Guard Corps' own virus database has a wide variety of deadly viruses and is fully functional.

Through the experiments on mutants again and again, there are still some viruses that can bring harm to mutants.

A large number of virus zones are being unfolded outside the base, along with self-detonating trucks.

Cai Ruichen's ultimate goal is only one, to let the other party die first before the mutants launch an attack on the base.

Of course, Cai Ruichen needs to pay a lot of price, constantly producing self-detonating trucks to ensure that they can cover an area of nearly 100,000 square kilometers outside the base.

The absolute kill radius of a self-detonating truck is two kilometers, and to cover such a huge area, it would take more than 8,000 self-detonating trucks to do so.

With such a huge quantity, Cai Ruichen naturally can't produce it all in just two or three months, so it needs a more reasonable and accurate layout, and the insufficient places can be supplemented with mines, and staggered with the set radiation area to ensure that too many attacks are not wasted.

Time is in the planned preparation of both sides, and day by day, the mutants in Iran have always maintained a rate of increase in the scale of one million.

And Cai Ruichen is also constantly busy with defense construction, or he keeps training, compressing his sleeping time to less than two hours every day.

In the blink of an eye, another two months have passed.

There are no more mutants in Iran, but in Iraq, from Erbil to Iran's western border, there are 90 million mutants.

However, the gene mutant that Cai Ruichen had been looking forward to for half a year was finally built. (To be continued.) )
