The third line of defense is a mix of subjects and combatants, with combatants handling heavy weapons and subjects capable of hand-to-hand combat.

The corpses trampled on the sea of fire, leaving behind many charred corpses, and finally walked out of the sea of fire, and the scarred and fragile low-level zombies could not withstand the attack of the test subjects at all.

Guarding tightly, the corpse tide seemed to stop moving again.

Yan Chongzhi in the command room was staring at the screen with both eyes, and the battle outside the building had entered a stalemate, which was the best situation he could see. Knowing that the corpse tide reached one million this time, Yan Chongzhi no longer had the luxury of winning, but just thought that he could delay time and wait for the reinforcements from the head office to arrive.

However, Yan Chongzhi's idea was a bit self-deceptive, if the corpse group was all composed of ordinary zombies, the defense line composed of test subjects could be impregnable.

But in the million-scale corpse tide, how can it be all low-level zombies, most of the zombies in the city are concentrated here, except for stage one, stage two can occasionally be seen.

Most of the zombies who extinguish the sea of fire with their bodies are stragglers who have no belonging and only have a simple will, and these weakest zombies rush to the front as cannon fodder.

They trampled through the flames and rushed through the minefields just to clear the way for the corpses behind them.

The mainstay of the Great Corpse Tide are those medium-sized corpse groups with a certain size, which is the main force of the attack.

With the will of the group, they have a high degree of cohesion and a strong sense of purpose, and usually there is at least one stage two zombie in the group.

As time went on, the guards in the third line of defense quickly felt the pressure.

Stage 2 zombies pop up from time to time and pose a huge threat to the entire defense line, and it usually takes several people to work together to kill them.

The attacking side gradually made changes, although the corpses did not know how to cooperate with each other, but enjoyed the strengthening of the will of the corpse king, and the offensive method was not limited to the mindless ramming, but looking for the weak and then led by the stage two zombies, attacking the weak.

As a result, the difficulty of defense increased dramatically, and the subject quickly became exhausted, and casualties began to occur on the Raven's side.

Through the screen, Yan Chongzhi can feel the despair and bloodshed on the battlefield, this is a war that cannot be retreated, there is no compromise and surrender between humans and zombies, the two ▼▼▼▼, m.▲.co※mstyle_tt; They belong to different ethnic groups, and the relationship between them is the most straightforward competition.

Under the leadership of the stage two zombies, the third line of defense was in danger, Yan Chongzhi sighed, although he was unwilling, he still ordered rationally: "Give up the third line of defense and retreat to the fourth line of defense!"

The difficult order was given, and the fall of each line of defense meant that the dark crow of J City was one step closer to destroying Miè.

But the paradox lies in the fact that if you don't take the initiative to abandon the defensive line, it will be too late to retreat when you wait for a complete collapse. Soldiers and test subjects fleeing for their lives in a hurry are likely to disrupt the layout of the fourth line of defense.

Instead of messing with oneself, it is better to take the initiative to give up and advance by retreating.

The last line of defense laid out by Yan Chongzhi exhausted the last resources of the Dark Crow sub-base, and all the guards wore gas masks, and once the war began, the alienation virus would be put into use.

These viruses, which are accidentally produced during testing, are highly corrosive and contagious, and are classified as weapons of mass destruction in human society.

Biochemical weapons like this will only be effective the first time when dealing with zombies, and individuals with weak adaptability and incomplete immune system evolution will be eliminated.

The first use will cause a large area of damage, but the few zombies that have adapted to this type of virus are likely to mutate a second time in the next few days.

Tens of thousands of secondary mutants, but just thinking about it makes my scalp tingle.

Such a method is undoubtedly to drink doves to quench thirst, but now Yan Chongzhi can't care about it so much.

In addition to a small number of human warriors, the fourth line of defense also concentrates the strongest army of test subjects of the Raven, and all the stage 2 test subjects with test numbers of less than 100 are concentrated in the fourth line of defense.

Approaching the Times Tower, the defensive line shrinks, and the positions that need to be defended are reduced, and the hundred phase two is enough to block attacks from all directions.

With the exception of these gas mask-wearing test subjects, the Raven's last resort is the aberrations of the fusion of biotechnology.

The twenty-five scavengers are like steel fortresses stationed at the foot of the Times Building, and unlike what Gao Jian encountered in the Yanlord Building, these scavengers should be the latest generation of products.

They're taller, stronger, and equipped with blades made of new materials, and each scavenger turns into a killing machine that never knows tiredness.

Biochemical viruses, killing machines, and hundreds of stages of two real bodies, the fourth line of defense has the least number of guards, but it is the most difficult level to break through.

The zombie tide entered the fourth line of defense, and as soon as they stepped into the virus-covered area, the zombies froze in place.

Then the zombies who entered first showed symptoms of severe illness, their heartbeats raced, and their gray skin appeared abnormally blood-red, mottled and very scary.

"This virus is not as high as E, but it is the most domineering of F-class viruses. "Gao Jian has devoured several F-class viruses, but he has never seen a virus that reacts so quickly, the zombie's mutated immune system is instantly broken, flowing in the bloodstream, even if it can't kill immediately, it can restrict behavior and movement, and can only obediently become a lamb to the slaughter.

Knowing the domineering of this virus, and even more aware of the power of the scavenger, Gao Jian decided not to wait any longer, and let him break through this last line of defense!

"Feast Corpse King - Level Suppression!"

The deafening roar of the corpse smashed his head and wanted to compete with himself for the control of the corpse group, Gao Jian commanded a group of 20,000 corpses, like a wild shark hunting in the sea of corpses!

"Gluttonous will!"

Greedy lust fuels every zombie in the clan to crave food and flesh to the extreme, and Gao Jian takes the lead and rushes to the last line of defense of the crows.

In the center of the sea of corpses that Gao Jian didn't see, a zombie in a yellow dress looked at a place with some surprise, and his control was torn to pieces by a roar.

Her gaze followed the direction of her thoughts, and a familiar figure appeared in her eyes, "That's ......"

The reaction of the mutant zombie in the brain domain became very strange, and it was the first time that this queen, who controlled the tide of 100,000 corpses in the north, showed such an anthropomorphic expression.

Gao Jian still didn't know until now that the corpse king who caused the zombie riot in the city was a mutant zombie in the brain domain, and he was thinking about being able to rescue him now!

The fourth line of defense is close at hand, with tall scavengers, formidable test subjects, and deadly viruses floating in the air.

Gao Jian's blood-red eyes saw everything in his eyes, but none of these could stop him!

As soon as Julie dies in Stage 3, there is no one in J City who can restrain Gao Jian anymore!
