Chapter 1533： Fishing in troubled waters

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

Accompanied by a large number of bubbles spewing out of the originally filthy river water, the air was filled with a choking and pungent smell, and from time to time, colorful firelights appeared, like countless ghosts with claws and claws, on the guards' heads. dance to tune.

The vibration of the cave became stronger and stronger, and a large amount of rock powder and gravel fell from the top of the cave "crackling" and smashed on the metal outer wall of the biochemical waste reaction kettle, making a "ding ding ding dong" noise, and more. Knocked panic.

Accompanied by bursts of crackling sounds that made the scalp numb, crisscrossing and dense spider web cracks appeared on the rock walls around the cave.

Although the initial crack was only the thickness of hair, the growth rate was quite amazing. It was quickly upgraded from "hair" to "centipede", and then from "centipede" to "venomous snake", and finally, from "venomous snake" to "venomous snake" The hungry "giant python" stared deeply from all directions and tried to devour everyone who was curled up in the ground.

Even the metal can, which was originally firmly installed on the reinforced concrete base, was shaking slightly in the increasingly strong vibration.

The smooth running sound suddenly became stumbling.

Creepy explosions came from inside several metal cans.

The repaired welds of several metal cans were squeezed and burst from the inside by the high temperature and high pressure poisonous gas again, and a bunch of poisonous mist like sharp arrows was sprayed out.

Countless monitoring probes were shaking their heads, countless meters were spinning like crazy, there were harsh beeps from countless alarms, the lights above people’s heads began to flicker frantically, and the blood-red emergency lighting system automatically turned on, but The light pouring down like a blood-colored waterfall can only make the guards who were caught off guard, revealing a trace of panic in the increasingly solemn expressions.

Chaos on top of chaos, and monsters.

Monsters are always more sensitive to earthquakes than humans.

On the surface of the underground river, before the first sulphur-flavored bubbles appeared, there were a large number of deformed and twisted snakes, worms, rat ants, and water spiders and water monkeys dormant on the riverbed, forming a black beast tide. swarmed towards the sewage treatment station.

These monsters are not very aggressive and combat power.

Usually, he doesn't dare to provoke heavy human guards, and he also detains and tortures the laboratory of 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 the powerful but rare doomsday beasts like the Diamond Nine-Headed Dragon.

These are as disgusting as slugs, and the number of snakes, worms, mice and ants is as large as ox hair, which is another level of trouble.

The elite guards of "Horizon" have been in the depths of the jungle, fighting with vicious monsters for many years.

With a single step, the shock wave blasted around the soles of the feet could crush dozens of snakes, worms, rats and ants into flesh.

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

And there is no clear direction of attack at all.

Just rambling around like headless flies.

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

But it is very likely to get into the depths of the sewage treatment system, between the criss-crossed pipes, the dead corners of human sight, and then die there, quietly rotting, fermenting, and forming flammable and explosive biochemical bombs!

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

As a result, the heroes who once fought with the beasts of hell, their rib fractures did not change their faces, and even grasped their broken ribs and inserted them deeply into the eye sockets of the beasts, they could only bite the bullet, cursing and shaking. In the cave, step on bedbugs, beat mice, and slaughter those ghosts with several pairs of wings, flies are not like flies, cockroaches are not like cockroaches, and locusts are not like locusts.

The best thing is that Meng Chao saw a huge gap torn from the river to the rock wall, and after twisting and twisting, it actually extended towards the hole where the sniper he most feared hibernated.

Seeing that the rock formations around the hole were twisted and deformed, the hole was squeezed to the size of a fist.

Snipers don't want to be squeezed into a can of luncheon meat alive.

Only half embarrassed, half sullen, he got out of the hiding place.

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

At first glance, a rock wall that was no different from the surrounding caves retreated and settled inward, revealing a dark passage.

Dozens of staff members wearing fully enclosed chemical protective suits and silver-white gas masks on their heads poured out.

They carry a lot of equipment to monitor the magnitude and trend of earthquakes.

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

At the same time, it also brought the guards higher-level chemical protective suits and gas masks.

After all, whether it is the boiling water of the river or the rupture of the metal can, including the deformed and twisted snakes, insects, rats and ants, after being trampled, the splattered blood, venom and acid quickly evaporate, all of which make the air flow in the cave. , filled with a deadly poisonous smog.

For Meng Chao, this was a real surprise.

Originally, he still had to work hard to find the entrance and exit of the Blood Pattern Lab!

Since the other party doesn't recruit themselves, the next thing is simple.

Meng Chao closed his eyes, calculated and waited silently.

As the earthquake intensity gradually increased, the damage to the caves continued to deepen. Not only did crisscross gaps appear on the exterior, but the internal rock layers were also torn and dislocated, resulting in the pipes embedded in the rock layers being cut off.

Conventional lighting systems have long been paralyzed.

The scarlet emergency lights also flickered.

Every 3.7 to 3.9 seconds, two-thirds of the emergency lights would 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 a master like Meng Chao, 0.34 seconds is enough for him to take a comfortable hot bath, eat a hearty meal on land and sea, and take a nap again to recharge his energy!

So, when darkness strikes next time, everyone's attention is either on the rambling snakes, worms and ants, or on the metal cans that are trembling and whistling wildly, or on the detection instruments. Beating and rotating indices, hands up.

Like a shadow with no thickness at all, Meng Chao jumped up from the underground river, wiped the blind spot of everyone's sight, advanced a full ten meters, and got into the bottom of the sewage pipeline that led directly to the underground river. Only a palm-wide gap!
