In just a few seconds, the otherwise noisy third floor became unusually quiet.

In the smoke of gunpowder, occasional electric sparks erupted from the dilapidated machine.

Liu Bei didn't hesitate, his figure flashed and he had already reached the 4th layer.

This level is noticeably different from the previous ones, there are no tons of thermal weapons, only one monster.

It was humanoid, five meters tall, covered in a thick stratum corneum that looked like elephant skin, but even the thick stratum corneum could not erase the terrifying bulge of muscles underneath.

Other than that, the most strange thing is that it actually has a steel head, which makes it look like a mechanical product rather than a living thing.

"Ahh

The entire 4th floor even trembled slightly due to the increased reverberation of the voice.

The monster's roar ended, and it rushed towards Liu Bei like lightning. As it runs, the ground begins to vibrate rhythmically.

It raised its huge fist and punched at Liu Bei.

The look in the ant's eyes made it instinctively uncomfortable, even angry.

"Uhhhh

Liu Bei looked at the monster in front of him with pity, he knew that it was a human before. It is not its will to become like this, and it is only a victim.

But now, it's too late. This monster has already had a nervous breakdown, lost itself, and cannot be saved.

Liu Bei also punched out.

The air is broken into particles, forming a circular band of air like a cloud.

Faintly, you can even see ripples rippling around. This is a shockwave.

"It's... How is it possible!" The director looked at the monitored picture in the monitoring room and couldn't help but scream.

"How can a human flesh and blood break through the sound barrier! This is absolutely impossible to ..."

As he screamed, the surveillance footage turned snow-white. Apparently, the 4th layer of surveillance equipment has been destroyed by the shockwave.

"Something must have gone wrong... Something must have gone wrong!" he repeated, thinking nervously, seemingly a little nervous.

It is a closed base, as the experiments are not allowed by humans, and it has little contact with the outside world to avoid exposure.

Therefore, the director did not know about the arrival of the emissary of the Universal Human Alliance. His knowledge of humanity is still limited by the limitations of the dust star.

Under his extremely nervous thoughts, he didn't notice that Liu Bei had broken through another layer at this moment.

Suddenly, he raised his head and stared at the footage of the surveillance with wide eyes.

"yes, he's definitely a robot, and a nuclear-powered robot!" he muttered.

"Hurry, stop him by all means, at all costs, use high-powered laser weapons, dispatch all test subjects!" he roared.

"But... , in that case, it is likely to lead to cannibalism..."

Because the spirit could not withstand the impact of physical power, it caused a mental breakdown. As a result, all the test subjects lost their minds, and only biological instincts remained.

Killing and surviving seem to be the ultimate meaning of their existence.

"Didn't you hear my orders?!" the director's tone was tyrannical.

"Okay, I'll do as you tell me to do. The voice on the other side was genuinely terrified.

At the same time, Liu Bei had already broken through to the 7th layer.

Suddenly, his figure flashed. Almost at the same time, a dazzling laser struck his position.

The ground made of special alloys melts instantly.

Dodging the laser's attack, Liu Bei's figure did not stop, and he ran forward.

At this time, the laser beam began to move, obviously locking on Liu Bei. It burns a crimson streak on the alloy floor and walls.

"Bang. There was an explosion. The entire laser began to shatter, and large and small debris fell to the ground.

Liu Bei raised his foot and kicked open the alloy gate leading to the 8th floor.

This level is different from the previous one, with countless various prison cells, which are used to hold various test subjects.

At the moment, they are all opened.

Having lost the restraints of their cages, they began to scuffle. The scene was extremely bloody, littered with shredded pieces of body and blood of various colors.

A monster closest to Liu Bei was gnawing on a mangled corpse. The corpse was fresh, and even its muscles could be seen twitching slightly.

The monster had red hair and a somewhat feminine face, apparently female. When she saw Liu Bei, her entire eyeball turned pure black.

"Wow~. It screamed and waved its hand. The broken alloy prison grates on the ground suddenly shot towards Liu Bei like bullets.

It has a powerful magnetic field that allows it to manipulate most metals.

The corpses of the surrounding subjects were apparently killed by it in this way.

It's just that this trick is obviously useless to Liu Bei. Real shells can't help Liu Bei, not to mention that the power of these alloy fragments is not as good as theirs.

Numerous alloy fragments stopped in front of Liu Bei, and then suddenly shot in all directions.

For a time, it rained blood, and many experimental subjects fell to the ground and died.

With this blow alone, a large number of test subjects have already died.

"This—" The director looked at the surveillance footage, his heart dripping blood.

In fact, many test subjects are not suitable for combat, but have specific abilities in some way. For example, some subjects have a particularly keen sixth sense, some have a particularly developed sense of smell, and so on.

Although they are not very combative, they are very valuable for research.

But now they're all dead.

Liu Bei's indiscriminate attack immediately attracted the attention of all the test subjects. They turned around and rushed towards Liu Bei in unison.

A monster was sticky, and everywhere the slime touched it was corroded and smoking.

A monster covered in skeletal armor even sparked as it ran, where the soles of its feet touched the ground.

A monster melted away as if it were frozen, and all the corpses it touched were devoured by it and became a part of it. It grows rapidly at a terrifying rate.

......

They are both very powerful, but they also have extremely obvious weaknesses. Otherwise, they wouldn't be a group of failed test subjects.

The slime monster was ignited, and it screamed and struggled miserably, but it was clearly useless. It is overbearing with its slime, but its flammable properties kill it.

The exoskeleton monster flew upside down, embedded in the alloy wall. Its bones are covered in cracks, and the flesh beneath it has long since turned into minced flesh.

A black dot appeared on the jelly monster's massive body, and it was poisoned. The black dot spread rapidly, and it squirmed as it tried to separate the part. But it only devours....

......

"How is this possible!" said the director for the fifth time.

"How could he see through the weaknesses of every subject in an instant?
