"boom!"

Asura Rhinoceros Beetle supported the wall with both hands, pulled its body out of the pit, and fell to the ground.

At this time, the brown shell on his body had been completely shattered, revealing the scarlet muscles wrapped inside the shell.

Looking at the powerful human with a calm face hundreds of meters ahead, Asura Rhinoceros Beetle couldn't help but reveal deep fear in his eyes.

Before Li Yun made his move, his sense of danger did not react at all, until Li Yun's figure appeared in his retina, the horror of looking directly at death surged over him like a tide.

"You...you definitely can't be human!"

Asura Rhinoceros Beetle shouted out this sentence in great horror.

At the door of the room, Genos barely stood up with the help of Saitama, staring blankly at Li Yun's back.

Although he had long known that Li Yun was very powerful, Genos did not know to what extent this powerfulness reached.

Until now, he had fought with the Asura Rhinoceros Beetle and saw Li Yun's unilateral crushing of the Asura Rhinoceros Beetle. Only then did he have a full understanding of Li Yun's strength.

But even such a powerful person as Mr. Li Yun once admitted that he was no match for Saitama.

So...how powerful is his teacher Saitama?

Thinking of this, Genos couldn't help but look at Saitama's profile beside him.

At the same time, behind Genos and Saitama, Dr. Genos, with his face covered in blood, stood in the corridor, covering his bleeding arm, staring blankly at the terrified Ashura Rhinoceros Beetle in front of him.

This is the most vicious and evil demon created since the establishment of the House of Evolution!

Could such a powerful demon actually show such a fearful expression?

...What is the origin of this group of people?

What kind of terrifying existence is that man with his back to him?

For a moment, Dr. Kinos' heart was filled with shock, and he felt that his previous worldview had become shattered.

After hearing the cry of Asura Rhinoceros Beetle, Li Yun not only did not answer, but showed a disappointed expression.

"Is this your last words?"

A calm voice tinged with disappointment came from a distance, instantly angering the Asura Rhinoceros Beetle, which was at low health.

“Damn it…Damn it!”

Asura Rhinoceros Beetle roared, clenched his fists tightly, and stomped his feet to crack the ground. After the shell was broken, the muscles on his body swelled instantly, and the original scarlet color gradually turned into a deep dark purple.

Green ripples emerged from his body surface and soon spread all over his body.

Fangs grew in his mouth. The horn, which was originally similar to that of a rhinoceros beetle, extended upward, changing from a hammer-shaped horn to a one-meter-long blade. Bone spikes protruded from the joints of his body.

The whole person seemed to have turned into a killing machine, and every part of his body was born for killing.

"Bang——"

After the transformation, Asura Rhinoceros Beetle took a step forward, and a violent aura emanated from him unscrupulously.

"This is my Asura Mode!"

Asura Rhinoceros Beetle grinned and said, "If you turn on this mode, I will lose my mind for the next week, and my fighting instinct will not subside until next Saturday!"

"Little human, be afraid! Tremble!"

"I will make you regret the decision you just made!"

The arrogant and noisy voice echoed in the empty room.

Li Yun sighed: "What a long story..."

Before he finished speaking, Li Yun's figure disappeared instantly.

The pupils of the Asura Rhinoceros Beetle, who was originally laughing wildly, shrank, and the danger intuition continued to echo in his mind at the highest volume.

"Where? Where?"

Asura Rhinoceros Beetle was anxiously searching for Li Yun.

Suddenly, he raised his head abruptly and saw Li Yun's figure appeared in the air at some point, only half a meter away from his head. His right fist was raised high like a sledgehammer, as if it would be swung out in the next second.

“…I got you!”

A hideous smile appeared on the face of the Asura Rhinoceros Beetle, and its dark purple claws, which were about an inch long, stretched out in an instant and grabbed Li Yun's head.

But Li Yun had no intention of dodging. He just looked at the Asura Rhinoceros Beetle calmly, and then under the other's gaze, he threw a punch steadily and quickly.

"boom!"

In an instant, terrifying nuclear energy burst out from Li Yun's fist.

A blue-green beam of light burst out and hit the Asura Rhinoceros Beetle.

The hard dark purple body exploded like a punctured water bag.

The purple flesh and smelly blood were vaporized and sublimated by the blue-green light column in an instant.

The remaining blue-green light beams splashed out, destroying the surrounding stone bricks and metal walls.

The shock wave violently raged near the center of the explosion, and the negative suction effect caused a huge dust column to rise from the ground. The rising dust column connected with the exploding smoke cloud to form a small nuclear explosion mushroom cloud.

This is the boxing style that Li Yun used after the battle with Saitama, combining Saitama's punching style with the help of nuclear energy.

In short, Nuclear Explosion Fist!

"boom!!"

A terrifying mushroom cloud rose in the underground room.

Genos inside the door and Dr. Genos outside the door were both shocked.

Zuo Yu helped Gu Changwen, whose body was covered in bruises, up from the ground. Looking at Li Yun who was engulfed by the mushroom cloud, he shouted, "Save some strength. Don't destroy this place. Dr. Kinos's research data over the years is still of some use!"

As soon as these words were spoken, Li Yun, who had just smashed the Asura Rhinoceros Beetle to pieces with a punch, immediately began to absorb the nuclear radiation spreading around him.

When Dr. Kinos outside the door heard his name, his body froze.

Saitama supported Genos and muttered mechanically, "Next Saturday, next Saturday, this guy's Ashura mode will last for a whole week, so... today is also Saturday?!"

“Ahhhh!!”

Saitama let go of Genos, knelt on the ground, and held his head in pain.

"Today is the supermarket's special sale day, I actually got the date wrong!"

Genos fell to the ground, staggered a few steps, and stared at Saitama in pain.

Suddenly, he said, "Teacher, the supermarket doesn't close until 10 pm. We can still get there in time!"

Saitama raised his head suddenly, looked at him hopefully and said, "Really?"

Genos nodded solemnly: "Yes."

Saitama immediately jumped up from the ground and waved to Zuo Yu who was not far away.

"Zuo Yusang, I have to leave for a while. I'll leave this place to you!"

Said, Saitama quickly ran to the wall and threw a punch.

"boom!"

The fist wind broke through the air, smoke and dust filled the air, and gravel and metal were squeezed outwards like a long dragon.

When the smoke and dust cleared, a terrifying tunnel with a diameter of more than 30 meters and a length of more than 50 meters appeared in front of everyone.

Saitama took a step forward and turned into a gust of wind, running towards the barren mountains and ridges outside the tunnel.

Zuo Yu pulled the corner of his mouth and asked loudly: "Do you want me to send someone to take you there?"

Saitama waved his hand without even turning his head, and his voice came from afar: "No need, it's faster to run!"

"Teacher, wait for me!"

Genos was shocked when he saw this, and staggered a few steps quickly, then activated the thrusters on his shoulders and legs, turned into a beam of fire, and chased after Saitama's back, which had turned into a black dot.

"What kind of people are these..."

Dr. Kinos stared at the two people who left with a dull look on his face.

Suddenly, someone tapped his shoulder.

Dr. Kinos' body stiffened, and he slowly turned his head, and indeed saw Zuo Yu's smiling face.

"Dr. Kinos, right?"

"Let me introduce myself. My name is Zuo Yu, and I'm the chairman of Kunlun Group. I admire your talent. So, do you want to change your environment and start your research on genetic experiments again?"

Dr. Kinos stared at him blankly: "...Ah?"

…

…

Three days later, on a street full of panicked pedestrians, a three-meter-tall toy monster who looked like an enlarged teddy bear was destroying things everywhere, waving his round fists and smashing the vehicles on the roadside one by one.

A strange laugh kept coming out of that horrible mouth that was obviously sewn together.

Just as the pedestrians on the street were terrified, a young man in a suit and glasses blocked the way of the Teddy Bear Monster.

The teddy bear monster was stunned for a moment, then opened his mouth sewn with thread and swung his fist to hit the young man on the head.

"Bang——"

The fist flew out of the air and blasted the teddy bear monster's head into a large piece of fur before the toy arm hit the ground.

Gu Changwen frowned, waved his hand to create a strong wind, blown away the flying fluff, then turned and walked towards the car on the side of the road.

"boom!"

The headless monster fell to the ground with a loud bang, causing the people fleeing on the street to freeze in place.

It was not until Gu Changwen opened the car door and drove away that the pedestrians came back to their senses as if awakened from a dream.

"He's a hero, he saved us!"

"I know him. He's a disciple of the Bangpu Gym, the 12th ranked hero in Class A, codenamed 'Iron Fist'!"

Everyone exclaimed in surprise and discussed excitedly on the street.

The noisy sound traveled hundreds of meters and reached the ears of Gu Changwen in the black car.

He sighed, looked at the road ahead and muttered, "A-class hero 'Iron Fist'... I did ask the association to give me a new name, but Iron Fist sounds too weak, doesn't it?"

"And why is the speed at which this hero advances so slowly..."

"At this rate, when will I be able to advance to S-rank?"

Gu Changwen complained to himself as he drove towards his apartment.

Not long after, he parked his car in the basement and took the elevator back to the apartment.

He opened the door and a familiar figure appeared in front of him.

Gu Changwen was slightly startled, then blurted out in surprise.

“Brother Li?!”

"You scared me. I thought there was a thief in the house... Why did you suddenly come to see me today? Where is Brother Zuo?"

Li Yun turned his head and looked at Gu Changwen with a slight smile: "He is still busy with the things that happened a few days ago at Kunlun Group."

Gu Changwen closed the door and walked into the living room, nodding and saying, "Indeed, there is too much data on the House of Evolution, and in addition to Dr. Kinos himself, there are dozens of his clones."

“It is not an easy task to properly place these dozens of talented researchers.”

As he spoke, Gu Changwen came to the bar next to the living room, picked up the teapot and gestured, "Tea or coffee?"

Li Yun smiled and said, "No need for that. I asked you to come here today because I have other things to do. We won't stay here for too long."

Gu Changwen was stunned for a moment, then put down the teapot and looked at Li Yun in silence.

After a moment, he said, "Are you finally going to tell me the truth?"

"Yes, I'm going to tell you the truth."

Li Yun smiled and ejected a gray mist coin, opening a silver light curtain in the living room.

Then, he stretched out his hand and said with a smile: "Come, I will take you to see the truth you want..."
