Through the observation pass at the highest top of Tianbi Mountain, several soldiers can overlook far away.

In the distance of their sight, clouds of smoke and dust rose from time to time, caused by the explosion of a cannonball.

Unlike the other teams, there were even hot air balloons in the sky of this team.

"Actually, these survivors out there are really good jobs, I just hope they don't underestimate these Amida protozoa."

In the last two years, the military has also seen different teams, and there is no doubt that this team with an air force is the strongest one at the moment.

"When that red smoke comes out, it doesn't feel dangerous at all. Once the danger is felt, it is too late. ”

In the past six months, these soldiers have long discovered the horror of the red smoke, but they have no way to notify the survivors outside that the entire living system is closed and they cannot go out.

"They have an air force, can we find a way to get a banner or something, and show it out......"

As he spoke, the soldier stopped his words, they were trapped here, and they couldn't go out at all.

"It's boring to live like this, Jinnima."

He slammed his fist into the wall.

It was really uncomfortable to watch your compatriots die one by one, but you could only survive in this dark base.

"Hold on, we have to live."

The other soldier clenched his fists in his hands, and a trace of red blood flowed from his lips.

"There are too many equipment and supplies in this base, and we are not living for ourselves, but because the world needs these things!"

However, this kind of vow, sometimes, it is useless to say too much.

There used to be hundreds of soldiers in the base, but now there are only a few dozen left, all because they can't hold on.

And now, with only a rudimentary air force outside, can it give them a glimmer of hope?

…………

In front of the road, Gong Zhiyun and the others led the elite troops to clean up the Amida protozoa hidden in the mountains on both sides.

The mountains in the southwest of China have brought infinite help to the survivors, but at the same time, the mountains that are high and low, full of hills and depressions, can also be used by the Amida protozoa.

Once upon a time, the few survivors who survived the red smoke died in the ambush of these guys.

In fact, many times, most of the survivors still look down on the Amida protozoa in their hearts.

These monsters that only use crowd tactics, and at most are just a little bit of long-range artillery, nothing more than relying on infection and not dying two points.

But, actually, these guys are also evolving.

From the various evolved classes, from the use of the red mist of the chemical plant, from the coordination of the various arms, it has been proved that they are not simple single-celled animals.

And now, Leng Hao's method of clearing the wilderness next door can just eliminate the threat of these monsters.

"Captain, those monsters are retreating. They left the chemical plant to us. ”

When Jiang Mingrui came to report, there was a hint of ridicule on the corner of his mouth.

If it's another team, that's fine.

However, the Rat Expedition paid a lot of price for it.

Jiang Xiaoyu, who risked her life to enter a chemical plant; He Qing, who never sleeps for medical analysis; Ma Tian, who controls the drone, and many people who have sweated for it, will not be fooled.

"Try it. Get ready. ”

Under Leng Hao's order, Tang Yida, who was wearing chemical protective clothing all over his body, as if he was a white ghost, began to enter the chemical plant with a rifle.

Behind Tang Yida and them, a large number of team members were preparing various supplies.

…………

"It's over. Their main forces began to enter the chemical plant......"

Listening to the continuous gunfire in the distance, several soldiers leaned against the wall helplessly, and their thin bodies seemed to have lost the power to support at this moment.

…………

Tang Yida and the others killed a lot of monsters, and even approached the tail of the chemical plant, and they could overlook Tianbi Mountain not far away.

"Bang!"

At this moment, suddenly, one of the blast furnaces of the chemical plant exploded, and a large amount of gas leaked.

At the same time, a large number of sulfuric acid cannon water bombs were fired accurately towards the blast furnace, and the yellowish water bombs fused with these leaked gases, and quickly turned into red smoke.

The red smoke, like a jellyfish with its claws open, spread quickly towards the entire chemical plant and even the periphery of the road.

"Bang!"

"Bang!"

In this increasingly dense red smoke, there are many water bombs that are increasing its concentration.

…………

"That kind of red mist appeared...... "A soldier who was watching this scene from afar slapped himself on the forehead, and then sat down on the ground in despair.

Another team of human survivors has been wiped out.

Witnessing this scene many times, they felt a deep sense of powerlessness, and tears flashed in the eyes of several soldiers.

The boy doesn't flick when he has tears, but he hasn't reached the sad place.

Why, human beings have to go through such an ordeal, why, they can only watch this scene again and again, but there is nothing they can do?

Compared with the extremely uncomfortable and depressed atmosphere among these soldiers, the morale of the rat expedition at this time was high.

"Oops, ouch, I'm mutated, mutated!"

After Tang Yida killed several Amida's protozoa in front of him, he screamed, and at the same time, his whole body deliberately twisted around.

"Fuck off, you guy can't twist Yangge!"

Just beside him, the laughter of Gong Zhiyun and the black eagle was heard not far away.

Around them, groups of warriors, dressed in chemical protective suits and like white ghosts, were all laughing.

"Don't argue, don't argue, there's a signal on the intercom."

Zheng Ximing suddenly let out a loud roar, which silenced the soldiers in the entire chemical plant.

"Hey, hey, Ye Huanying? I'm Zheng Ximing. Yes, we're all right now. ”

"Don't worry, Jiang Xiaoyu can do it, we men will not be worse than her......"

Just as Zheng Ximing shouted triumphantly, suddenly, his headphones lost signal.

"Hemp sells batches...... this signal is the unreliable ...... of Zhen Nima"

Zheng Ximing scolded at once, but the next moment Leng Hao's somewhat unhappy question came from the earphones.

"Zheng Ximing, who are you scolding?"

"Captain? Me, I'm saying the signal is not good......"

When Zheng Ximing in the red mist stammered to explain to Leng Hao, in the base of Tianbi Mountain, on an instrument beside the soldiers lying on the ground, red and blue signal lights suddenly flashed.

"We ......"

One of the soldiers' eyes widened as he stared at the glowing signal light.
