Yi Yun guessed that the stairs were very long, but they turned out to be longer than he had expected.

Even after crossing a thousand steps, he saw no sign of the stairs coming to an end.

Yi Yun's leg would have broken if he hadn't become an evolver. Luckily now the spiritual energy had increased his stamina to another point.

After passing a thousand more steps, only then did they reach the end of it.

Even with his current stamina, Yi Yun's knees were still weak from exhaustion.

At the end of the stairs, there was a large gate, about 5 meters high, it was made of steel but it was rusty.

Bamv...

When Yi Yun saw the gate, he suddenly heard a thumping sound behind the gate, it seemed that something was hitting the gate.

At first it was only once, but after that there was more banging sound behind the gate.

John paid no heed to the thumping, he casually approached the gate.

He then reached out his hand to the handle of the gate, after holding it, he immediately pulled it so that the gate began to open.

Roar... Roar... Roar...

Right after that, dozens of roars echoed from behind the gate.

Yi Yun saw dozens of strange creatures that looked like humans but had the faces of beasts, some with the faces of monkeys, crocodiles, and even birds. They are about twice as tall as humans.

He thought the black bear-like monsters just looked scary, but these creatures made him feel a little horrified. They look more like horror creatures.

Even the sound of their roars sounded hoarse as if they had no throat.

[VOC has detected 18 level 1 mutants around you, VOC can extract one of them.]

Yi Yun suddenly heard the voice of the VOC in his mind.

'Mutant? Why are they called mutants?' He couldn't help but be surprised.

He had no time to think, they charged toward John as soon as the gates opened.

He was ready to run, but luckily the middle-aged man was still standing quietly.

As the mutants arrived in front of him, he casually sent his fists towards them. Yi Yun saw his fist suddenly turn to iron, the moment it hit the head of one of those mutants, the head instantly exploded like a bursting balloon.

After that, his iron fist suddenly transformed into a sword.

He then slashed the sword at the mutants' necks. He moved like a monkey, jumping from place to place, in no time, he managed to decapitate all those mutants.

Blood spurted out of their necks so that they formed a pool of blood. Seeing that, Yi Yun felt so disgusted that he almost vomited.

The scene he saw now was completely different from when he killed the male evolver before.

Back then, he didn't even see blood because the laser instantly burned the man's blood, but now there was so much blood that they looked like a pool of mud.

Zhong was unaffected by the blood, obviously he was used to such things.

John then glanced at them and said, "let's go."

He entered the gate. There, there is a crypt with many passages.

Yi Yun wanted to try extract the corpse of one of the mutants, but John's presence made him hesitate to do so.

He finally chose to follow him first.

But just as he was about to pass through the pool of blood, he flew his body so he wouldn't step on the pool of blood. He was still able to fly his body through it.

The sight as he flew caught Jhon's attention, he couldn't help but ask "did you use a new potion?"

"Yes sir." Yi Yun nodded.

"What do they ask of you?"

"They asked for nine level 2 monster cores," Yi Yun replied.

"Nine?"

The always expressionless John changed his expression for a moment.

Seeing that, Yi Yun became even more certain that level 2 monster cores were extremely rare.

Even so, he chose not to ask about it. But the existence of the mutant intrigued him.

"Sir, they?" He asked while glancing at the mutant corpses behind.

He felt an ominous premonition from them.

John looked at them before replying, "they are people who have failed to use transformation techniques, it causes them to lose control over their bodies and minds. They are considered dead and return to square one, but their old bodies will continue to be like that, living like monsters."

Yi Yun, "..."
