After the mud and sand from the riverbed were absorbed by Meng Chao’s vitality magnetic field, it became a second layer of skin draped over his totem armor, converging its light and killing intent. He merged perfectly with the foul-smelling mud below the sewage pipe.

There were a total of four guards and workers within ten meters. It was as if they were facing a great enemy and were tired of dealing with it. However, not a single one of them saw Meng Chao.

It was not until a few water rats with two heads ran down the sewage pipe in a panic that everyone’s eyes were pulled over.

Meng Chao was already prepared.

He gently flicked out a broken bone that he had picked up from the riverbed.

The broken bone was the size of a grain of rice. It stuck close to the ground and silently hit the joint between one of the water rat’s two heads.

The water rat squeaked in pain and jumped.

It seemed to realize that in the darkness ahead, there was a terrifying existence that it could not afford to provoke. Driven by its survival instinct, it changed direction and entered another sewage pipe.

The four guards and workers shifted their attention.

The next two-thirds of the emergency lights went out, and another “dark period” arrived.

The moment darkness devoured the cave, Meng Chao leaped up from the bottom of the sewage pipe.

Like a bolt of black lightning, he darted to the center of the sewage treatment system, where the reactor and the metal tanks were the densest.

It was also the place where the guards were the densest.

The gazes of the seven or eight guards were like thorns, tightly entangling the reactor and metal tanks.

Before Meng Chao arrived, a few pieces of metal that were as thin as cicada’s wings and as sharp as blades were already shooting out of his fingertips.

With precision, they pierced into one of the metal tanks, which had been repaired, and it began to crack.

The metal tank immediately exploded.

A large amount of corrosive liquids that were hundreds of degrees hot and sticky spurted out of the tank.

Due to the sudden change in pressure, it vaporized instantly and turned into a colorful poisonous fog that bared its fangs and brandished its claws.

Even though the guards and staff were wearing three layers of protective clothing, the poisonous fog was still expanding.

Seeing the poisonous fog that seemed to have a life of its own, they were shocked, breaking out in a cold sweat.

They quickly waved the fire extinguisher and the mithril stabilizer spray, spraying white bubbles at the poisonous fog. They tried to keep the poisonous fog contained within a range of three to five meters.

How could they see Meng Chao? Just as they were spraying the foam around, a phantom-like figure flashed into the depths of the poisonous fog and the foam.

Whoosh! Whoosh!

The emergency light flashed for the third time and also became extinguished soon after.

This time, Meng Chao hid behind a tall and muscular guard who looked like a humanoid tank.

This guard appeared to have been injected with some kind of gene reagent that had not been approved.

There was a heavy bomb embedded within every one of his muscle fibers.

Normally, one would not be able to train to achieve such a deformed and developed body.

His combat ability was as astonishing as his body size.

Flames of war that were visible to the naked eye gushed out of his lumpy muscles.

It made him seem like he was stuck in the middle of a cave, like a burning torch.

There was no doubt that crouching behind the muscular man was a very risky move.

However, Meng Chao had observed the muscular man’s mode of movement calmly and confirmed that he had a certain flaw in his perception. As long as he activated the Walking Corpse technique to the maximum, using the muscular man’s surging vitality magnetic field to conceal his movements could be as effective as “darkness under the lamp.”

Moreover, the pathway that led from the back of the strong man to the rock stratum and the BloodFlower laboratory was also the closest.

As expected, the strong man was probably the leader of the guards. He was known to be fierce and evil.

Faced with the situation where the earthquake was getting increasingly intense and the entire cave could collapse at any time, the strong man got so angry that smoke was rising out of his seven apertures. His furious face was so twisted that even evil ghosts would break out in cold sweat.

His roar drowned out the loud sounds from the depths of the underground river.

His saliva was also like a dense barrage of bullets, poking holes in the guards’ faces.

None of the guards dared to meet the brawny man’s gaze.

Naturally, it was even more impossible for them to discover Meng Chao, who was hiding behind that man.

Thus, when the next round of darkness came, Meng Chao was akin to a black arrow shot out by a ghost. He dashed straight toward the entrance and exit of the rock wall.

Before the emergency light came back on, he had already infiltrated the interior of the Blood Flower laboratory.

It was a narrow, high-tech corridor.

The corridor was covered in surveillance cameras, pressure sensors, and infrared scanners.

It was to ensure that even if a mutated rat sneaked into the laboratory, they would be able to scan and lock on to it at the first moment.

However, that was during normal times.

Right now, the sewage treatment system, which was separated from the tunnel by a wall, was being attacked by an earthquake.

Meng Chao had stimulated the accompanying mineral vein, which was hidden in the depths of the underground river, and it was releasing an unrelenting spirit magnetic storm.

Although the destructive energy released by this spirit magnetic storm was far less than one percent of the Red Radiance Jade vein that Lin Chuan had detonated a few years ago, it was more than enough to temporarily disable the monitoring equipment in the underground laboratory within five to ten minutes.

“The monitoring facilities and the precision instruments here should be disabled.

“Next, I just need to be on guard against the staff in the laboratory!”

Meng Chao’s ears were like a radar that was rotating nonstop.

He could hear everything within a hundred meters of the tunnel—breathing, heartbeats, hurried footsteps, angry curses, shouting, the monsters locked in the laboratory, and the abnormal movement of the planet’s magnetic field. Meng Chao went crazy, pulling the chains and hitting the fence hard before he could make a distinction between all the clattering sounds.

Meng Chao heard dozens of footsteps coming from all directions toward the tunnel.

The tunnel was the only way for the Blood Flower laboratory to access the sewage treatment system. There were no forks on either side, so there was nowhere for Meng Chao to hide.

But that was not a problem for him.

He noticed that the propeller-like roar of an armored airship kept coming from above his head.

He determined that it was the underground laboratory’s ventilation system. It was overloading which was why the sewage treatment system’s explosion caused by the earthquake managed to firmly block the laboratory from the outside. Nothing could penetrate it in the slightest.

The ventilation system was the most important thing to any underground structure.

Not to mention, it was a Blood Flower laboratory, which was carrying out biochemical experiments and producing highly toxic gases as well as deadly spores.

Soon, Meng Chao found the ventilation duct’s air outlet.

He raised his arm and casually put his palm, which was wrapped in a gauntlet, on the air outlet.

The spirit magnet that had solidified into the gauntlet immediately melted into mercury, slipping into the air outlet and into the depths of the ventilation duct.
