There are generally only two ways to improve monsters, one is the evolution and improvement of one's own physique, and the second is to increase one's strength through a large amount of energy devouring.

The injections researched by the old madman belong to the pinnacle of biological evolution, and self-breakthrough is obviously impractical, so if he wants to defeat Yun Yi, he can only seek a large amount of energy injection.

And as time slowly passed, most of the living people in the room were eaten by him, and only the old man was left squatting in the corner with people shivering.

When the smell of blood in the air became stronger and stronger, it was two young people who rushed up uncontrollably, they didn't actually want to go, but the force behind them was too great.

"Energy...... Energy ......"

Grabbing the head of a young man with one hand, the old madman showed a mouthful of bright red teeth, and there were still a few pieces of flesh hanging between the sparse teeth, which looked extremely terrifying.

"Boss...... Old-timer...... No...... Don't ......"

The crotch of the two relatives was already soaked, and a peculiar smell slowly got into the nose of the old madman, who was originally the pride of the heavens in the land of creation, but now they were scared to the point of urine.

"Disgusting!"

The old madman is not completely crazy, the replenishment of a large amount of energy has gradually brought him back to his senses, and the two people in front of him are really too bad, and he is indeed a little unspeakable.

"Yes, yes, we're dirty, beg the adults to let them go... Ask for ...... adults"

As soon as the two of them heard the old madman's normal words, they hurriedly wanted to flatter, they thought that they would escape this catastrophe, but they found that they were speechless.

Crushed the heads of the two of them casually, the old madman licked the remaining blood on his hands, and now he is completely out of touch with people, so he doesn't have to abide by the rules and etiquette of human beings.

Feeling that the energy in his body began to be abundant again, the old madman remembered Yun Yi who had insulted him before, he glanced at the people in the corner evilly, and flashed into the corridor once.

Yun Yi has been waiting for the old madman, knowing that it is impossible to run away if this trouble is not solved, the land of creation is extremely large, and this test has just begun.

Step by step from the bottom to the present, Yunyi believes that he relies not only on the pit system and luck, but also on his own perseverance.

"It seems that you are not afraid of death, since you still dare to wait for me, but this time I will only shoot once, if you survive, I promise not to trouble you!"

The old madman was calm, not at all as manic as he had been in the house, he was half-crouched, already in an attacking position.

"Okay, I will definitely let you die this time, as long as you dare to come, I will make you regret meeting me as an enemy!"

Yun Yi was expressionless, nodded and looked at the old madman, he didn't make any movements, but the killing intent flying behind him made him look very weird.

"What? You say you can kill me? ”

The old madman was slightly stunned, and even the posture of the attack became a little distorted, and he looked at Yun Yi suspiciously, wanting to see what the conspiracy was.

"You're no match for me, you should know for yourself, I didn't know how many times the creatures in the room would be able to replenish you, but this time you definitely won't have another chance! My Yunyi's dignity is inviolable, and the first time it is a warning to you, if you dare to be obsessed...... Hum! ”

With a cold snort at the end, Yun Yi's momentum suddenly began to skyrocket, he took out a dagger, and a layer of cold light appeared in his eyes.

"You...... You...... You ......"

Three times in a row, the old madman didn't finish his words, originally he wanted to attack Yun Yi, but his body didn't listen to him.

The scene just now is still fresh in his memory, Yun Yi's perfect defense again and again made the old madman almost unable to find any flaws, he believed that Yun Yi could fight back just now, and he would definitely not feel good.

"You're threatening me, do you think I'm going to be afraid of you?"

Finally, the old madman who figured it out also became angry, and after he finished speaking, he glared at Yun Yi and took a step back cautiously.

"I'm strong now, and no one can do anything to me!"

Seeing that Yiyun Yi didn't react, the old madman screamed again, and he continued to retreat, and quickly retreated to the door.

"No one can laugh at me, no one can master my weaknesses, no one can do it, no one can do it!"

The old madman glanced at Yun Yi again at the door now, and suddenly a dodge got in, he was frightened by Yun Yi's threat just now, so he had to go to the old man again to vent his anger.

The brave wins when they meet on a narrow road, compared to force, often the strongest one can have the last laugh, Yun Yi is not a monster, but he is stronger than a monster.

"Ah...... Help me...... Someone's coming......"

There was another scream from the room not far away, and this time Yun Yi didn't care whether those people were dead or alive, he swaggered past the door and went straight to the end of the elevator.

Gently pressed the elevator switch, the elevator soon opened automatically, Yun Yi walked in one step, turned around and stood towards the corridor.

He didn't know where the dungeon was, so he pressed a button, and when the elevator door began to slowly close, he saw the old madman standing outside the door.

"In the future, I will definitely kill you with my own hands...... I'm going to be strong during this time, so you don't want to die here......"

The old madman's voice gradually disappeared, and the elevator began to fall at a rapid speed, Yun Yi still maintained a expressionless face for a few seconds, and finally let out a long sigh of relief.

The old madman is definitely not his opponent, this conclusion must be understandable, but the process of killing the old madman must be very difficult, which is also what Yun Yi has already thought.

Working hard in someone else's territory, it is obvious that he is impatient, in order to prevent the story of the snipe and clam competing for the benefit of the fisherman, of course Yun Yi will not do such a stupid thing.

However, the main reason why madmen are madmen is that it is manifested in their thoughts, they are an extreme, how can they be willing to be threatened by others.

Thinking that he would have a madman enemy in the future, Yun Yi's face couldn't help but show a wry smile, he had no good way now, he could only hope that the old madman would kill some more enemies, so as to make the creation land more chaotic.

……

In the open laboratory, the old madman began to kill like crazy again, his whole body covered in blood, and a trembling intestine hanging from his neck.

Because he really can't let go of that bad breath, the old madman takes the living people here as the object of venting, he doesn't eat a person, but everyone doesn't even have a complete corpse.

The old man who led the team was not weak, but he became vulnerable in the face of the real master, and when the last guard around him died tragically on the spot, his whole body was lifted up by the old madman.

"Everything is you, everything is you, you have to repay the humiliation I have suffered, you have to repay ......"
