Li Duo sneered, today he can give up 100,000 lives, and tomorrow he may send himself to the guillotine for the sake of the overall situation, the father and son of the Liu family are like a cold machine, always looking for a way to maximize benefits.

"Then I deeply regret it...... But for now...... I hope that the Li Duo brothers will not let the sacrifices of these people be useless......"

Li Duo loosened Wang Tengyi's clothes, Wang Tengyi calmly dusted off the folds of his clothes, and then took out the gas mask from his backpack and put it on his face.

The same is true of the soldiers around him, Li Duo also got one and brought it to his face, although he didn't need it, but at this time, he couldn't do any non-human behavior, so as not to cause unnecessary trouble.

At this time, the square was already in chaos, and no one could have imagined that the fuel canisters supplied to the central tower would actually spew out deadly poisonous gas!

Not only the fuel pipes, but even the fuel delivery pipes buried under the ground spilled out a scarlet mist, and a large area of high-concentration black light virus spilled in all directions, causing one survivor and the garrison to clutch their throats and fall to the ground in pain.

They were rolling in pain on the ground, large swaths of black and red blood coming in and out of their bodies, indescribably terrifying.

Although there were no open fuel tanks in the control area, many soldiers breathed in the black light gas escaping from the pipes and became infected in an instant, and the rest of the soldiers all stepped back, took off their gas masks, and covered their faces.

"What's going on!"

There were officers roaring.

"Report sir! Someone replaced the fuel with black light poison gas, I'm afraid this is a premeditated biochemical attack! ”

The soldier on the side said to the officer while firing at the infected comrade next to him.

They are no longer the inexperienced rookies at the beginning of the apocalypse, they have experienced countless encounters with zombies, and they are already familiar with this situation, this black light poison gas is an improved subspecies, and the infection ability is comparable to that of a virus of level 4 zombies, as long as ordinary people are contaminated, there is only one way to die.

At this time, the defenders in the control area had already begun to cover the firepower, and the twelve energy turrets were all in operation, and one after another energy bullets rained out!

The survivors screamed, some of the uninfected companions who had not yet been infected were torn to shreds in an instant, and many more of the infected staggered to their feet, roaring, waving their blood-stained limbs, and surging towards the tide in the control zone!

"It's now! Walk! ”

Wang Teng shouted one by one, he kicked open the door, and rushed out first, followed by others, rushing out one after another.

A considerable part of the garrison survived, and to this day, even those who were regarded as cannon fodder by the Chaos were neatly configured, wearing gas masks, shooting zombies everywhere while quickly approaching the central tower.

The defenders have fierce firepower and advanced weapons, but their numbers are too small compared to the zombies, and with the addition of some mutated zombies, the outermost defense line was quickly broken through, and they withdrew towards the interior of the tower together with the garrisons who fled in.

Li Duo and the others mingled inside, and easily entered the heavily guarded central tower on weekdays, the entrance gate of the tower was blocked to death, and the sound of zombies banging on the door outside was constantly roaring!

In fact, not only the fuel tank outside leaked, but even the pipes leading to the rooms on each floor in the tower also leaked a large amount of black light and poisonous gas, some humans were infected, frantically searching for fresh flesh, gunfire continued throughout the building, and there was chaos everywhere.

It's not that the fuel pipeline is of bad quality and in disrepair, but that Wang Tengyi added a large amount of strong corrosive gas to the black light poisonous gas, which corroded and destroyed the fuel pipeline, causing a large amount of gas to leak out!

"Time is pressing, follow me!"

A lieutenant from the guard came up to them and whispered.

This is a dark line from within the enemy, the success of this operation, his efforts are indispensable, Wang Teng nodded, beckoned behind him, and the group came to the freight elevator and marched towards the lower floor.

"Below is the biochemical laboratory serving the Chaos Clan, which is also the main target of this operation."

Wang Tengyi said to the others beside him, his words paused, as if inadvertently glanced at Li Duo, and said meaningfully: "Remember, there are no innocent people inside, I have no other requirements, only three words of truth: burn, kill, smash!" ”

This is really simple and violent, Li Duo secretly said in his heart that it is a pity, in the central computer here, a large amount of scientific research materials are stored, if he is given time, he can steal them all.

It's just that time waits for no one, and if they don't wreak havoc as soon as possible before the Chaos Clan reacts, and if it drags on for a long time, they will all be blocked here.

The situation in the laboratory was just as bad, with a considerable number of researchers suffering from infection, but the defenses here were tight, and the guards around them killed several scientists who were about to be corpsed, and quickly calmed down the scene.

As soon as the elevator door opened, Wang Tengyi and others walked out of it.

"Who are you? Trespassing without permission is a capital offense! ”

Their uniforms were very different from those of the garrison, so as soon as they saw Li Duo's garrison uniforms, their faces suddenly changed, and they raised the weapons in their hands and roared loudly.

"Do it!"

As of now, what else is there to say, just fight, with Wang Teng's orders one by one, the agents in the front row rolled over tactically, quickly hid behind the cover, and began to shoot frantically at the people in the laboratory.

The weapons on both sides are upgraded versions* of weapons, and these weapons are so powerful that even low-level evolutions can lose half their lives if they take a single shot.

The gunfire was deafening, the golden streamlines in the air intertwined and flew, and from time to time someone screamed and fell to the ground, the time was short, the battle was over, the guards were all wiped out, and a group of wolf-like agents quickly began to act.

The strength of the guards is not weak, but compared to the agents who have undergone biochemical transformation, they are still far behind, they have been accurately shot in the head by bullets, corpses are scattered, and blood has formed a small river on the ground.

"Da Da Da!"

The agents scattered like locusts in transit, and began a swift slaughter of the researchers who were hiding, some of them burning scientific research materials, destroying portable hard drives, cutting off the life support systems of the culture tanks, and even some of the refugees who had been captured for experiments.

It's just that these are not what Li Duo needs to care about at all, at this time, Li Duo has come to a corner of the laboratory, in front of the closed safe.

Although this safe was in a sealed state, it was only in Li Duo's arms that the fragment of chaos had already trembled violently, and its surface seemed to exude a scorching flame, which made Li Duo's heart stir with it.

He was sure that another piece of chaos was hidden in this safe.

This safe also needs genetic verification, but Li Duo didn't have the leisure mood at all, he grabbed the safe and tore it open violently!

In the safe lay a simple gray fragment, and the moment he saw this fragment, a smile appeared on Li Duo's face.

The efficiency of the task force was swift, and the heavily patrolled agents knew everything they were doing, and it wasn't long before everything in the lab was destroyed.

A large number of C4 bombers have been placed on the load-bearing columns and walls for a long time. Medicine, these formula-modified works are enough to destroy and collapse the entire Central Tower!

It's just that at this time, Wang Tengyi's face was not very good, his face was pale, and he muttered to himself: "There must be something negligent, the quantity and quality of these biochemical weapons are not enough at all, how can this laboratory only have this scale!" ”

At this time, his face was full of anger, his eyes were scarlet, and he still had a little elegant appearance, but time did not allow him to think too much, and the anxious voice of the upper-level soldiers left behind came from the walkie-talkie: "Director, retreat quickly, there are already large troops chasing towards the bottom!" ”

"Withdraw!"

Wang Tengyi shook his head, and finally burst out of his mouth with these words, he clenched his fists tightly, and then opened them weakly.

The group did not dare to take some stairs, and chose the safety staircase, but halfway through, they encountered the reinforcements of the defenders.

When the two sides met, they didn't say a word and opened fire directly.

The defenders were prepared, and most of them, all armed with power armor, were invulnerable, carrying heavy weapons with ferocious firepower, and the powerful fire bombarded the walls of the stairwell.

"Whew!"

Li Duo greeted him, his wind whip arm swept across, and in an instant, a tyrannical air storm was set off in the narrow stairwell, and the storm swept through, and the power armor was cut and torn apart.

Li Duo nodded and quickly came to the first floor with the people behind him, at this time, there were already people waiting for them, and as soon as they appeared, they were attacked by a crazy onslaught in an instant!

More than a dozen agents died instantly, and the others were suppressed on the roof of the building, unable to raise their heads at all, only the strongest Li Duo and Wang Tengyi rushed out, dodging the fierce rain of bullets while crashing into the crowd!

"Li Duo, it's you again! You're damned! Today is your time of death! ”

The commander is a Chaos Evolution, as soon as he saw Li Duo, his face was immediately full of surprise, and his heart was full of pride, Li Duo was the mortal enemy of the Chaos Clan, and his head was very valuable.
