Oh My God! Earthlings are Insane!

When Meng Chao surfaced again, the sewage treatment station of "Horizon" was already in chaos.

Accompanied by a large number of bubbles gushing out from the already filthy river water, the air was filled with choking and pungent smells, and clusters of colorful flames appeared from time to time, like ghosts with countless teeth and claws, above the heads of the guards. dance to tune.

The vibration of the cave became more and more intense, and a large amount of rock powder and gravel fell from the roof of the cave "crackling" and hit the metal outer wall of the biochemical waste reactor, making a "clinking" noise, and even more so. The knock made people panic.

Accompanied by bursts of scalp-numbing crackling sounds, criss-crossing and dense spider web cracks appeared on the rock walls around the cave.

Although the initial cracks were only as thick as a hair, they grew at an astonishing speed. They quickly upgraded from "hair" to "centipede", then from "centipede" to "venomous snake", and finally, from "venomous snake" to The hungry "Giant Python" stared deeply from all directions and tried to devour everyone curled up underground.

Even the metal tank, which was originally firmly installed on the pedestal made of reinforced concrete, trembled slightly amidst the increasingly intense vibrations.

The originally smooth running sound suddenly became stumbling.

There were creepy bangs from inside several metal tanks.

The repaired welds of several metal tanks were again squeezed and burst by the high temperature and high pressure poisonous gas, spraying out bunches of poisonous mist like sharp arrows.

Countless monitoring probes are shaking their heads, countless meters are spinning like crazy, and there are piercing beeps from countless sirens. The lights above people's heads start to flicker frantically, and the blood-red emergency lighting system is automatically turned on. The light pouring down like a blood-colored waterfall can only make the guards caught off guard, and their increasingly dignified expressions reveal wisps of panic.

To add chaos to chaos, there are monsters.

Monsters are always more sensitive to earthquakes than humans.

On the surface of the underground river, before the first sulfur-smelling bubbles appeared, there were a large number of deformed and twisted snakes, insects, rats and ants, as well as water spiders and water monkeys dormant on the river bed, forming a black beast tide. Swarm towards the sewage treatment station.

The aggressiveness and fighting power of these monsters are not strong.

Normally, I dare not provoke human beings to guard the laboratory with heavy soldiers, and even imprison and torture high-level beasts.

But driven by the desire to survive, they instinctively wanted to stay as far away from the restless associated mineral veins as possible.

Compared with powerful but rare doomsday beasts such as the diamond nine-headed dragon.

These snakes, rats, rats and ants, which are as disgusting as slugs and are as numerous as a cow's hair, are troubles on another level.

The elite guards of "Horizon" have fought against vicious monsters in the depths of the jungle for many years.

With a light kick, the shock wave blasted around the soles of the feet can crush dozens of snakes, insects, rats and ants into a pulp.

The problem is that there are too many snakes, rats and ants.

And there is no clear direction of attack at all.

Just scurrying around like headless chickens.

Even if they can't tear apart the iron walls of human beings.

But it is very possible to get into the depths of the sewage treatment system, between the criss-crossing pipes, the blind spot of human sight, and then die there, rotting and fermenting silently, forming flammable and explosive biochemical bombs one after another!

That will bring great trouble to the subsequent operation of the sewage treatment system.

Therefore, the heroes who once fought with hell beasts, their ribs were broken without changing their expressions, and they could even hold their own broken ribs and insert them deeply into the eye sockets of the beasts, could only bite the bullet, curse, and kept shaking. In the cave, step on bedbugs, beat mice, and cull those ghost things that have several pairs of wings, flies are not like flies, cockroaches are not like cockroaches, and locusts are not like locusts.

The most wonderful thing was that Meng Chao saw a huge gap torn from the river to the rock wall, and after twists and turns, it extended towards the hole where the sniper he feared the most was dormant.

Seeing that the rock formations around the cave were distorted and deformed, the cave was squeezed down to the size of a fist.

A sniper doesn't want to be squeezed into a can of lunch meat.

He could only get out of the hiding place half embarrassed and half sullen.

At this time, the rock wall behind the sewage treatment system suddenly shook regularly.

At first glance, a rock wall that looked exactly like the surrounding caves receded and sank inwards, revealing a dark passage.

Dozens of staff members wearing fully enclosed chemical protective suits and silver-white gas masks rushed out.

They carried a great deal of equipment to monitor earthquake magnitude and trends.

There are also several prospectors wearing diving suits, preparing to dive into the underground river to explore the source of the earthquake.

At the same time, the guards were also provided with chemical protective suits and gas masks with higher grades.

After all, whether it is the boiling of the river or the rupture of the metal tank, including deformed and twisted snakes, insects, rats and ants, which splash out after being trampled to death, the rapidly evaporating blood, venom and acid all make the cave with poor air circulation Inside, filled with deadly poisonous mist.

For Meng Chao, this was a real surprise.

Originally, he had to spend a lot of effort to find the entrance and exit of the blood pattern flower laboratory!

Since the other party didn't ask for it, the next thing is simple.

Meng Chao closed his eyes, calculated and waited silently.

As the intensity of the earthquake gradually increased, the damage to the cave continued to deepen. Not only did criss-cross gaps appear on the outside, but the internal rock formations were also torn and dislocated, resulting in the cutting of the pipes embedded in the rock formations.

The conventional lighting system has long been paralyzed.

Scarlet emergency lights flashed on and off.

Every 3.7 seconds to 3.9 seconds, two-thirds of the emergency lights will go out, causing about 55% of the cave to fall into darkness with extremely low visibility.

This process will last from 0.3 to 0.4 seconds.

For an expert like Meng Chao, 0.34 seconds is enough time for him to take a comfortable hot bath, eat a hearty sea and turf meal, and take a good night's sleep to recharge his batteries!

So, when the darkness strikes next time, everyone's attention will either be on the scurrying snakes, insects, rats and ants, on the metal tanks trembling crazily and whistling, or on the testing instruments that are going crazy. Jumping and rotating indices, hands up hours.

Like a shadow with no thickness at all, Meng Chao jumped up from the underground river, brushed the blind spot of everyone's sight, advanced a full ten meters, and got under a section of sewage pipe leading directly to the underground river. There's only one palm-width gap!
