Deep City, in a certain abandoned factory, thousands of people are gathered around to watch a thrilling combat match.

This is an underground boxing ring, attracting countless fearless fighters who are drawn by the allure of money.

In the ring, a black chubby man and a HuaXia man are fighting, the latter has been knocked down, with blood leaking from the corners of his mouth and eyes. After being punched down by the black chubby man, he had no strength to stand up again.

"Get up! You waste!"

"Weren't you touted as the 'Fist Demon'? Get up quickly!"

"Darn, you're pathetic! Boasting about your ten consecutive victories, you're just a piece of trash!"

"Darn it, I staked all my wealth on Guanghao! What should I do?"

"I borrowed two million to bet on him, I'm doomed if he loses!"

"Kill him! Kill him!"

"Harris, show no mercy!"

Most of the audience, holding tickets that represented their bets, couldn't believe that this match between undefeated Fist Demon- Guanghao and Black Tornado- Harris, turned out to be so one-sided!

Guanghao was actually being beaten so badly by Harris!

"Da...Damn it... I can’t accept defeat..." Guanghao forcibly opened his swollen eyes and looked at the black chubby man – Harris, who was swinging his fists and shouting at the audience.

He was supposed to win the match today, but someone drugged the drink he had before the match, making him feel weak and unable to even mount a proper defense.

"It must be Huang Guangli! I refused to cooperate with him in match-fixing, so he wants to ruin me!"

Guanghao cursed under his breath. Huang Guangli was his boss, who had previously proposed the idea of throwing a rigged boxing match, but Guanghao had refused. And so, Huang Guangli resorted to such devious methods.

As Harris approached him, ready to strike the last blow—this was an underground boxing match with no referee. Llife and death, wealth and status were all predestined, and even if his opponent were to beat him to death, there was nothing that could be done.

Was he really about to meet his end here? Despair filled Guanghao’s heart.

On the second floor of the abandoned factory, a middle-aged man dressed in a suit, slicked back hair watching the ring with a triumphant sneer, "Guanghao, you're only to blame for your lack of cooperation. With your death, Harris will rise to the top, stepping over your body to become the next undefeated boxing demon!”

This man in the middle was none other than Guanghao's agent and the top figure in the underworld—Huang Guangli.

In the midst of despair, Guanghao suddenly saw his surroundings disappear, and found himself in a blank, void space.

"What is this?" Guanghao wondered.

An elusive voice informed him, "Guanghao, you have been linked to the 'One Punch Kill' system."

Guanghao was even more puzzled, "One Punch Kill system? Is it like the cheat-like existences in novels?"

"Correct," the voice replied, "Earth is about to enter an era of mutation. The system discovered this space and decided to choose a host within. Your temperament is unique and was chosen by the system."

"And what's your purpose?" Guanghao asked.

The One Punch Kill System replied: "Each assignment you complete for me, you'll earn 'Kill Points'. You also stand a chance to earn treasures. These points can be used to instant-kill enemies! Different level enemies require different amounts of kill points."

Guanghao said, “I understand, what do I need to do now?”

The One Punch Kill System answered, "I am presenting you with 10 kill points. Please complete the first assignment I have given you—Kill Harris with one punch! Once the mission is completed, you will receive 20 kill points, and a body-refining technique— 'Golden Bell Shield."

"I understand, let me go."

Guanghao took a deep breath, realizing that every cloud has a silver lining. Apparently, he is the chosen one. The era of earth’s mutation is fast approaching and he would be at the leading edge of this era!

The void space disappeared and Guanghao's vision returned to the arena!

As if time had never moved, Guanghao saw Harris's heavy elbow aiming for his temple!

"One-hit kill!"

Suddenly, Guanghao was completely rejuvenated, he sprang up from the ground and hit Harris's elbow hard with his right straight punch!

"Bang!" Harris's chubby face twisted; he felt an indescribable tremendous pain, the kind of pain that was spreading from his elbow to his entire body!

How can this be? How is it possible? This guy was supposed to be dying, how can he have such a strong strength!

"Ah!" Harris was sent flying by this powerful hit, directly knocked out of the ring, flew to the second floor and punched a big hole in the iron sheet wall of the second floor!

His massive body was embedded in the wall.

"..."

Huang Guangfa was dumbfounded, unable to utter a word. What is happening? Is this a movie? Can it be more exaggerated?

"..."

After a silence of three seconds, the entire stadium suddenly burst into thunderous cheers!

"He won! He won!"

"Did I freaking see that right? Harris was sent flying by one punch from Guang Hao?"

"Damn, Harris had a bad defeat. The iron plate was smashed into a huge hole, I guess all of his bones are broken!"

"Thank God! We're saved now! We're saved! I don't have to jump off the building!"

"The undefeated boxing demon, you're my idol!"

The crowd was in an uproar, the referee wiped the sweat off his forehead, and cautiously approached Guang Hao, lifting his arm to signal that he had won.

Guang Hao turned his head to the second floor, staring at Huang Guang Fa, who was sitting on a leather sofa, and made a slitting throat gesture at him.

"Fuck."

Huang Guang Fa harshly extinguished the cigar in his hand!

The subordinate next to him said, "Fa bro, Guang Hao won this time. We're probably going to lose at least forty million."

Huang Guang Fa gritted his teeth, "Find some men to take care of him. Remember, I want him to never see tomorrow's sun."

"Understood!" That subordinate seriously nodded.

Huang Guang Fa snorted and walked out of the factory without looking back.

Wang Hao received the prize from the referee, and then left amidst the cheers of everyone. A number of heavily made up women tried to catch his eye, but he took no notice.

After leaving the abandoned factory, Guang Hao sped home on his Harley motorcycle.

Defeating Harris with one punch cost 8 insta-kill points, but fortunately, after completion of the mission, he had obtained 20 insta-kill points and a copy of "Golden Bell Cover".

Now he has to rush back home to practice the "Golden Bell Cover" given by the system!

He can't only rely on the insta-kill system; he has to become stronger himself. This way, he can keep the insta-kill points as a life-saving trick, instead of wasting them on some worthless people.

Guang Hao's home was in an ordinary apartment complex. He returned home, didn't bother to shower, and immediately clicked to use the "Golden Bell Cover" in the system.

As it was a martial art reward from the system, he didn't need to practice, and directly mastered the basic level of "Golden Bell Cover". Of course, to reach a higher realm, he still has to rely on his own cultivation.
