According to Xuan Muli, in the depths of this underground, there is an upside-down pyramid.

The pyramid has 12 floors, and no one knows how big it is and how deep it can go underground.

Bai Yi walked down the stairs all the way, and with the help of the light brought by the lightning ball, he slowly looked around.

The staircase spirals, starting from the position of the black iron door, and winding vertically, as if to penetrate the entire underground.

The spiral staircase is surrounded by cold walls and rocks, and ordinary people will surely die if they are attacked by monsters hiding in the shadows.

......

I don't know how long I walked, I don't know how long it was, but the staircase was still empty and silent.

Not only was there no sound, but even the room-like building didn't appear.

The only thing left is the darkness that can't be seen.

......

Finally, after about half an hour, Bai Yi slowly stopped.

At this moment, a huge bronze door quietly appeared in front of him.

Approximately six meters high, the bronze door is pitch black and has a mirror-smooth surface that reflects a little bit of light under the illumination of a ball of lightning.

Strange to say, the spiral vertical staircase reached the position of this door and disappeared.

It's as if everything around it exists for this bronze door.

Bai Yi raised his head and saw that the top of this bronze door was actually engraved with the word "one" the size of a human head.

After glancing at the word "one", Bai Yi lowered his head again, slowly raised his hands, and with a slight force, he directly pushed the bronze door open.

The bronze door was pushed open, and a thick and suffocating smell of blood rancid came over the face in an instant.

For this stench, Bai Yi looked as usual, waved his right hand lightly at the position of his nose, and looked at the innermost part of the door again.

The inside of the bronze door is pitch black, but the overall outline looks a bit like a laboratory.

......

"Bang dang!"

Just when Bai Yi's eyes were looking inside from outside the door, suddenly, somewhere inside the door, a dull voice suddenly sounded.

The sound sounded like something had knocked over some instrument.

This voice appeared very suddenly, especially in such a dark and oppressive environment, it was even more eerie and terrifying.

In this regard, Bai Yi looked calm and remained unmoved, as if he was deaf to the strange sound of "clang".

......

"Eat ......"

"Eat ......"

"Hungry ......"

"Eat...... You're ...... Good...... Hungry ......"

Just when the aftermath of the clanging sound had not completely fallen, in the depths of this pitch-black laboratory, a giant tentacle the size of a bucket suddenly poked out of the darkness and poked violently towards the location where the white clothes were.

This giant tentacle is turquoise all over, with teeth-like barbs on the surface, and green blood the size of a bean slowly trickles down from the fangs barbs.

The giant tentacle is like a swimming snake, its movements are extremely flexible, and in one breath, it strikes in an instant.

When it hit, the giant tentacles blew a piercing sonic boom in the air, and the turquoise whip shadows also drew countless phantom trajectories in the darkness.

Standing outside the bronze door, the white clothes stood with their hands in their hands, their demeanor was calm, and they did not feel the slightest panic in the attack of the giant tentacles.

"A Dark Tyrant?"

"The aura is so chaotic that it seems to have devoured many of its kind, forcibly evolving to the tyrant level. ”

The white cloth muttered in a low voice, still ignoring the attack of the giant tentacle that was already close at hand.

"Forget it, seeing that you are in such pain, then I will help you get rid of it!"

Bai Yi slowly raised his head, looking at a corner in the darkness, and then the next moment, he slowly raised his right hand, towards the dark corner, suddenly bent his five fingers, and then held it slightly.

This grip is plain and unremarkable, and it is like flowing water.

But also under the grip of the white cloth, the unknown dark tyrant monster that was originally hidden in the darkness suddenly let out a heart-rending scream.

The scream was extremely painful and miserable, and it sounded like it was under some kind of unparalleled pressure.

But the moment this scream just sounded, the next second suddenly stopped.

At the same time that the screams stopped abruptly, the giant tentacles that had been maintaining the shape of a swimming snake suddenly turned into flying ashes at the same time, and with a snort, they flew away all over the sky.

After killing the unknown dark tyrant alive, the white cloth strode forward, and in a few steps, he had already completed all the distance of this room and appeared at the end of the room.

......

At the end of the room, another bronze door stood here, and this bronze door was the same as the bronze door at the front of the staircase.

This time, Bai Yi did not hesitate, reached out and gently pushed, and easily opened it.

When the bronze door is opened, the scene behind the door is revealed.

Behind the door, there is still a spiral-shaped vertical staircase, this spiral staircase, leading to the deeper underground, how far-reaching, is unknown.

Because of the previous experience of the first spiral staircase, Bai Yi did not delay too much, but accelerated his pace, and used the body magic technique ten, directly transcending time and space, almost in the blink of an eye, he had already arrived, in front of the next bronze door.

The bronze door was stained with blood and smelled of decay.

If you get a little closer, you can't help it, and you will feel a strong feeling of vomiting and nausea.

Above this door, a large two-character is carved into it.

This time, Bai Yi did not directly reach out to touch the bronze door, but aimed at the bronze door from a distance of one zhang, and it was just like that.

With the push of such a void, a monstrous wave of qi suddenly appeared, and then a photograph bombarded the portal.

This wave of air was like a stormy wave on the majestic sea, swift and violent, and the door of the bronze door, the moment it was bombarded by such a ferocious force, suddenly became crumbling.

After about a few seconds of crumbling, the entire bronze portal suddenly made an earth-shattering explosion, and then with a bang, the bronze door, along with the surrounding walls, began to collapse towards the room inside.

Without the obstruction of the bronze door, the scene inside was gradually exposed.

The room on the second floor is completely different from the pitch black of the room on the first floor, and the environment here, from the inside out, from top to bottom, is filled with an endless blood red.

This blood-red color is like blood, exuding a strong smell and malice.

The blood-red light reflected the entire room, and from a distance it looked like an asura hell, making people stop and tremble.

As the bronze door and the surrounding walls collapsed into the room, there were several bloody figures at the end of the blood-red room, but they suddenly staggered to their feet from the ground.

These blood-drenched figures, after sensing the arrival of the white clothes, began to pounce on them one by one.

They are not very fast, staggering, like drunken drunks, unable to stand on their feet.

As these bloody figures continued to get closer, their true faces became clear.

I saw that these bloody figures were actually walking corpses with skin peeled off.

Not only that, but these walking dead monsters, they don't even have eyes, noses, mouths, ears.

And these important sensory organs have been completely replaced by small black holes.

These bloody monsters are constantly flowing bright red blood from their bodies.

After the blood flowed out, all the dripping fell to the ground.

After dripping on the ground, it quickly corroded into small holes.

"Are there a few more Dark Tyrants!"

Bai Yi watched these figures keep rushing towards him, and his brows couldn't help frowning.

He didn't expect that just after reaching the second layer, so many tyrants appeared, and it seemed that the foundation of the Titan Laboratory was really profound.

If the empires and alliances in the human world rashly send people to break in, I am afraid that they will end up with a total annihilation.
