Simon and Sosia thought for a moment, then nodded eventually.

"Na Chen, you are careful alone, remember not to force yourself, if you see something tricky, withdraw first. Simon said.

Chen Yuan nodded, and continued to walk forward.

After walking for about twenty minutes, I finally reached the end of the passage.

At the end of the passage is illuminated by countless high-powered light bulbs, and suddenly it is a spacious barbed wire platform.

From time to time, there was the sound of steel bars hitting the ground, and the sound of iron cables dragging and pulling.

Chen Yuan took Ling Bo microsteps, quietly pasted it on the iron net, and looked down.

Seeing this, Chen Yuan was directly stunned in place.

It was an underground factory of tens of thousands of square meters, the concrete floor was full of sewage, and there were thousands of iron cages on the left side, large and small, and the mutated beasts in the iron cages kept waving their claws and smashing the iron net.

The sound of the iron ropes dragging on the ground was not from the beasts, but from the iron cages covered with black curtains not far away.

There is a testing machine on the right, followed by experimenters wearing chemical protective suits.

Directly in front of it was a large formalin pool, bordered by a rusty conveyor belt with mutated human corpses, some with strange claws.

Some have a snake tail.

In the middle was a laboratory, where several white coats were pressing against a young man in his twenties, injecting a bottle of light blue liquid into the young man's body.

"Ahh He kept pumping his arms in pain, but his hands were tightly clasped by the white coat.

But Rao was still struggling in pain, and after about two minutes, his body suddenly trembled like a fat man just now.

The bones of the body made a series of crisp sounds, and the body also grew more than ten centimeters taller, but unlike the fat man, this person did not become an irrational lump of meat, but his right arm changed rapidly, gradually becoming hideous, terrifying, and growing jagged claws.

As time passed, the arm continued to expand rapidly, eventually matching the size of a man's body.

Rao is Chen Yuan frowned when he saw this scene.

"What the hell is this organization working on?"

"Roar!" Suddenly, the mutated young man in the lab yelled into the sky. The sound actually formed a shockwave in the shape of a circle, bringing out the circular deformation of the metal laboratory.

But the young man, after letting out a hoarse roar, suddenly fell to the ground as if he had been drained.

The body that was originally swollen quickly shrank!

Lying on the ground with a pale face, he saw that he was already out of breath and less in breath!

Outside the door, a white lab coat in a protective suit took out a lab board and recorded it all.

"Subject 12,860 failed the test and can't withstand the wolf serum!"

After the recording, he continued: "The test failed! Destroy the test subject! Continue the test!"

"!" looked at the humans on the right and the beasts on the left, Rao couldn't help but scold with Chen Yuan's concentration.

"Could this damn STS be studying mutations?"

No wonder, no wonder there is such a heavy formalin taste!

Chen Yuan's gaze fell on the iron cage covered with a black curtain again, listening to the sound of iron chains cutting across the ground, his heart was cold.

I'm afraid that the one locked in there is a test subject who has lost his mind that has been mutated by some kind of beast serum!

"I have to report the situation to the senior as soon as possible!" Chen Yuan smacked his lips, turned around and prepared to leave quickly.

But before Chen Yuan could turn around, a cold and heartfelt sentence suddenly sounded like a maggot on the tarsal bone: "It's wonderful! This is the evolution of human beings!"

The voice was a little hoarse, but with a madness and obsession that could not be concealed.

"Who!" Chen Yuan's half of his body instantly became cold.

Although his cultivation has not reached the top level now, there are only a handful of people who can appear behind him silently like this!

Chen Yuan shouted, almost instinctively, jumping back, distancing himself from the owner of the voice.

"Hahaha!

By jumping back, Chen Yuan finally saw the appearance of the person behind him, it was a man in his thirties, not tall, wearing a suit with black stripes, a face painted pale, dark black circles painted under his eyes, he painted his nose red, and the corners of his mouth were cracked with a bewitching and weird smile.

"Welcome to my puppet show, this one called Boom Road. ”

"Is this customer satisfied with my puppet show?"

The man kept laughing as he spoke, but it was that smile that gave Chen Yuan a very uncomfortable feeling, as if a powerful invisible hand had grabbed his heart.

"Who are you!" Chen Yuan said vigilantly.

"Hehe, what a naughty guest, even though I was uninvited to watch the show, but he still asked me who I was. ”

"So, introduce yourself. I am the host of this puppet play, and the guests call me ...... Black Clown!"

"Now that our S-class guest has finished watching my puppet theater, it's time for the curtain to end!"

As he spoke, the corners of the black clown's mouth suddenly raised a strange arc: "As for the reward, I think I'll pay for it with your head!"

"Hahaha!"

In the midst of the shrill laughter, the black clown touched behind him, and there were already six more juggling knives between his fingers. 536 Literature

"Let's try throwing knife tricks. With a flick of his wrist, three flying knives the length of his index finger rushed straight at Chen Yuan's head.

Chen Yuan's eyes shrank, he didn't dare to be careless, and immediately used Ling Bo's micro-step, leaving an afterimage in place, and the flying knife shot against Chen Yuan's ear on the stone wall behind him.

Rumble!

The three throwing knives slammed into the stone wall, making a loud noise, and actually smashed the stone wall into three bottomless holes.

Chen Yuan glanced at the three small holes with the corner of his eye, and immediately swallowed a mouthful of saliva.

At the same time, a warm current flowed down his face.

Rao is Chen Yuan made Ling Bo Weibu in time but his forehead was still scratched, if the black clown threw out the flying knife, Chen Yuan was half a point slower, but he was afraid that he was already in a different place now.

The black clown looked at the blood flowing from Chen Yuan's forehead, and the smile on the corner of his mouth became even more excited and crazy.

"Hahaha, what a pity, this guest, could have let you see a beautiful blood show!"

"But you don't have to worry! Hehe, my black clown's puppet theater will definitely have the most perfect ending!"

As he spoke, the other three flying knives also shot towards Chen Yuan.

"...... This madman!"

Looking at the flying knife that was rapidly enlarged in his eyes, Chen Yuan scolded angrily.

But at this time, he couldn't help but have too much time to react, almost instinctively, Chen Yuan smashed out of the three flying knives in front of him!

"Bajiquan!"

The surging aura above the fist wind condensed, and a punch roared, like a lion galloping on the grassland, biting the murderous flying knife thrown by the black clown.

"Haha! My throwing knife is not something that this kind of kitten can bite indiscriminately. The black clown sneered.

Immediately afterwards, the three flying knives actually penetrated into Chen Yuan's Baji Boxing little by little, as if it was devastating, but in an instant, it was to cut most of the Baji Boxing's fist style!

"The little lion is going to die, audience friends. Let's take a look at the hunters!"

Chen Yuan's eyes shrank, he couldn't have imagined that the Baji Fist he had played with all his strength would be so vulnerable.

"Fight left and right!"

"Xuanming Divine Palm!"

At the moment of crisis, Chen Yuan had no choice but to break the cauldron and sink the boat, only to see him spread his feet and step on the broken iron net with a standard horse step, and at the same time, his eyes were shining with golden light.

At the same time as the left hand punches out the Baji, the right palm splits out.

Suddenly, a cold chill dispersed.

Then, a three-meter-long ice silver dragon roared out with Chen Yuan's left hand.

"Roar!" The moment the silver dragon appeared, it immediately let out a huge roar, and rushed towards the Baji Fist fist wind that was about to dissipate again.

"Boom!"

The three flying knives collided with the silver dragon, but it was like a mountain colliding with a mountain, and there was an earth-shattering sound immediately, and then the ice flew away, and the two completely collided together.

"Hmm, it's interesting, hahaha, it's interesting!" The black clown was not stunned for a moment when he saw his three throwing knives shot down, laughed to himself, and then spread his hands.

"Guest, let's listen to this killing sonata. ”

After the black clown finished speaking, his hands were like magic, and suddenly rows of bright silver throwing knives appeared, and those flying knives were there

Jumping between his fingers and dancing gently to the melody of his fingers.

It was obviously a flying knife with a bloody smell, but it became an elegant rhythm tool in the hands of the black clown.

"This one, it's called Doom!" the black clown opened his mouth and smiled, leaking out a row of dark yellow teeth, and then he pointed his finger, and a row of flying knives came from the front to slash at Chen Yuan.

There are thirteen flying knives in this row, and their destructive power is naturally not comparable to those three flying knives just now.

Chen Yuan just glanced at it, and his scalp tingled for a while.

He had already tried his best with the three flying knives just now, and now with these thirteen flying knives, how could he fight hard?

"Run!"

Chen Yuan didn't dare to stay for half a minute, and the situation here could only be solved by the high-level personnel of Da Sixi. Now he has only one way to run.

With a flicker of his body, Chen Yuan had already urged Ling Bo to take a slight step with all his might, leaving an afterimage in place, and his body stepping on the wire ran towards the exit of the tunnel at an incredible angle.

Thirteen flying knives almost grazed Chen Yuan's scalp, and the sharp blades directly cut a huge crack in the rock wall behind him.

The crack was bottomless, and all that could be heard was the echo of the throwing knife slicing through the stone wall.

"Gollum!" Chen Yuan glanced at the stone wall that had been cut open and swallowed a mouthful of saliva.

If he is caught by the pervert of the black clown, I am afraid that there will be no chance of survival.

"This section is called parting!" the black clown frantically commanded the flying knife in the air, but the posture in his hand was extremely elegant, like a real conductor.

"Whoosh!"

Two rows of flying knives flew towards Chen Yuan, one left and one right, Chen Yuan dodged, narrowly and dangerously dodging the first group of flying knives, but the second row of flying knives had already rushed to Chen Yuan's face, and there was no way to avoid it!

"Fight!" Chen Yuan gritted his teeth.
