I transmigrated at the same time and became the King!

One-Punch Man World.

Earth.

In an abandoned area on the outskirts of City A.

A man with a menacing claw mark near his eye and a height of over 187cm was stretching his limbs and doing warm-up exercises.

He is none other than KING, ranked seventh in the Hero Association and known as the strongest on Earth!

Besides his title of hero, he also has a name.

Ze Feng.

He is not the native King of this world, but a transmigrator from Earth.

Three years ago, after KING was attacked by the Tiger-level monster Octopus Man, he fell into a deep coma. At that time, Ze Feng was reading the One-Punch Man manga. But who would have thought that he would be transported to this world by mistake and replace the original KING in this world.

Unlike the original story, Ze Feng, after becoming KING, also began his own journey to become stronger.

Although KING's luck is indeed extraordinary, this little broken planet called Earth is just so full of disasters and is definitely the most unlucky planet.

Especially in this world of One-Punch Man where the power levels are off the charts, Demon-level monsters are as rare as dogs, and Dragon-level monsters are everywhere. You can rely on luck, and if you're unlucky one day, you might just die on the spot.

Knowing the fate of this world, Ze Feng met Saitama early in his transmigration and trained with him to surpass his limits, improve his strength, and deal with monsters.

Although he is not bald like Saitama and does not possess the terrifying fighting power to kill everything with a single punch, his own strength has reached an extremely terrifying level, with half of his leg exceeding the limits of human capability.

At that moment, a bald man with a signature braised egg hairstyle was standing right in front of Ze Feng, picking his nose expressionlessly, looking completely indifferent.

He is none other than Saitama, KING's good friend, also known as the Bald Demon King!

In a true sense, it has broken through the limits of human existence, and its combat power is unknown.

"Hey King, you look really serious this time. We're just having a friendly spar, there's no need to be so serious." Saitama noticed Ze Feng's serious expression and his lips twitched, his face covered in sweat.

To be honest, in the three years since he met KING, this wasn't the first time he had faced KING. At first, things were fine, and the two were evenly matched. But as the number of matches increased, the gap between them was widening to the extreme.

The King who was once his equal has now been left far behind.

However, Saitama was also very fortunate that King was able to maintain his passion for fighting him, which was one of the few times that could stir up his emotions.

Especially in gaming...

"If you don't go all out against Saitama, you might get knocked out with one punch."

"My invitation to fight you this time is not just a simple sparring match. Some time ago, I consulted Bang and obtained a boxing technique he created when he was young. It is extremely compatible with my heartbeat and can unleash destructive power beyond the limits of the body. I have only just mastered this boxing technique and have never used it in actual combat."

"Looking at this whole world, there's no one else who can help me but you. Please, Saitama."

Ze Feng rubbed his hands together, a sharp glint in his eyes, every cell in his body was mobilized, and he entered a state of combat readiness.

"Thump thump~! Thump thump~! Thump thump~! Thump thump~! ..." A deafening roar, like muffled thunder, resounded from Ze Feng's heart, as astonishing as a machine engine.

This is... the roar of the Emperor Engine, and also a sign that Ze Feng's heart is racing as he enters battle mode.

As the roar of the Emperor Engine reverberates in all directions, Ze Feng's blood flow accelerates, and his speed, strength, and reaction time all experience a qualitative leap.

For an ordinary person, a heartbeat that loud would have caused their heart to explode from the strain.

But Ze Feng is different.

His heart is special; no matter how fast the blood supply is increased, his heart can withstand almost all the pressure.

To paraphrase a Freljordian: The heart is the strongest muscle!

At the same time, Ze Feng also assumed a fighting stance, his muscles were highly tense, his veins were bulging, his blood was flowing faster in his blood vessels, and a lot of heat was rising from his body.

This is a sign that blood flow is accelerated and bodily functions are activated.

"Alright, I'm also curious about what's so special about martial arts, so... go all out!" But facing Ze Feng's all-out attack, Saitama remained calm and composed, maintaining his simple style.

"Heart Explosion Release Fist!!" The moment he finished speaking, Ze Feng rushed forward and arrived in front of Saitama. His heart roared loudly, and the powerful fist pressure tore through space, bringing with it the power to destroy everything, and went straight for Saitama's face.

Sensing the destructive power of the attack, a hint of surprise flashed across Saitama's usually impassive face.

Instead of facing enemies without flinching as he had before, he raised his right hand and grabbed King's fist in defense.

A deafening roar erupted.

The devastating punch pierced through Saitama's body, creating a massive chasm thousands of meters wide behind him, stretching as far as the eye could see.

The Heart Explosion Release Fist, as its name suggests, involves the heart responding to the shockwave of the fist, unleashing tremendous power.

However, this move would put an unimaginable strain on the heart, but Ze Feng was an exception.

The original owner of this body, KING, would have his heart pounding so loudly that it could be heard by everyone within a hundred meters when he was slightly nervous.

It's easy to imagine how special his heart is and how much stress it can withstand.

Especially after Ze Feng took over this body, his three years of relentless training had already honed his physique to a level beyond human limits.

Explosive Heart Release Fist became Ze Feng's signature skill.

The louder the roar of the Emperor Engine, the more astonishing the power of the Heart-Burning Release Fist becomes.

"Wow, what a powerful punch! It's definitely different from before." Saitama's dormant emotions were stirred by Ze Feng's punch, and he even had the urge to stretch his legs.

Ze Feng has indeed become different from before. This is the first time since he went bald that he has been emotionally stirred by a battle.

"I told you long ago, I'm different now than before, Brother Saitama." Ze Feng's lips curled up slightly, revealing a confident smile, while a cold glint flashed in his eyes.

The roar of the Emperor Engine intensified once more, and Lin Ze instantly sprang into the air, disappearing from his spot.

A whooshing sound rang out.

Ze Feng vanished from his spot like a ghost. Due to his ultra-high-speed movement, his body created countless afterimages around Saitama, forming an encirclement.
