Devil Fruit: Invincible from the Tremor-Tremor Fruit

The Heart Demon Assassin was just a small episode.

Mu Bai stood in the dim laboratory, his eyes firm and deep. Doflamingo was wearing a white lab coat, holding a slender test tube in his hand, with a faint fluorescent light flashing inside, as if carrying some mysterious power.

"Are you sure you want to do this, Mu Bai?" Doflamingo's voice echoed in the laboratory with a subtle tremor.

Mu Bai did not hesitate, he nodded: "Yes, I need these 'undead' to have some of my genes, they will become my most loyal warriors."

Doflamingo took a deep breath, he knew what this decision meant to Mu Bai. He said no more and began to concentrate on the experiment. He gently inserted the test tube into Mu Bai's arm and extracted part of his genes. The process was not painful, but Mu Bai could feel his vitality being slowly drawn away.

As the genes were extracted, Doflamingo began to integrate them into the newly created "undead". These "undeads" were originally just lifeless shells, but now, they gradually began to possess Mu Bai's characteristics. Their eyes became firm and their bodies became strong, as if Mu Bai's shadow was reborn in them.

After years of devil fruit experiments and the integration of materials from various other world copies, it can be said that these unprepossessing undeads are the biggest biological weapons of the Eternal God Church and Mu Bai. Once the experiment is successful, the combination of artificial devil fruits will truly push Mu Bai to the throne of the king of the underground world!

Ming Ge, who was wearing sunglasses, raised his glasses and then said to the experimenter next to him: "Put in the experimental testers, those death row prisoners."

"Okay!"

The experimenter quickly pressed the switch.

In the dim 100-meter cage, a large number of death row prisoners were put in. They were originally in confusion and fear, not knowing why they came here, and even less knowing what fate they would face next. When they saw the "undead" monster in front of them, their fear instantly reached its peak.

The "undead" monster stood in the center of the cage, with muscles as strong as a sculpture, and eyes flashing with fiery light. Its appearance seemed to shroud the entire cage in a strange and terrifying atmosphere.

The prisoners were panicked. Some of them screamed and retreated, trying to escape from this terrible monster; some collapsed on the ground, trembling all over, without even the courage to raise their heads; others stared at the "undead" with wide eyes and horror, as if they wanted to see something from it.

The cage was in chaos, and panic and despair spread rapidly among the prisoners. They were already in a desperate situation, and now, the appearance of this "undead" monster made them feel unprecedented helplessness and despair.

However, the "undead" seemed to not care about all this. It stood there quietly, looking at each prisoner with indifference, as if evaluating their value.

The "undead" monster stood in human form, and its two-meter-tall body looked unusually burly in the cage. Its skin is a deep purple-blue color, like a ghost in the dark night, or a monster born in the mud, giving people a cold and mysterious feeling.

The most eye-catching thing is its eyes, which are glowing with dark green light, flashing a cold light in the dim cage. These eyes seem to be able to see through all the darkness and look directly at the fear deep in people's hearts. When it slowly scans the surroundings, the dark green light is as erratic as a ghost fire, which is chilling.

Its facial contour is slightly distorted, revealing a kind of inhuman weird beauty. Under the purple-blue skin, the muscle texture is clearly visible, showing its powerful strength. Although its body maintains the human form, every detail reveals the characteristics beyond human beings, which makes people feel deeply terrified while being amazed.

Among the death row prisoners, there is a strong man, he is burly and muscular, even in the cage, he still maintains an unyielding momentum. He watched the "undead" monster in the field with a cold smile on his face.

He suddenly snorted coldly, and the sound was like a strong wind in the cold winter, with a kind of sharpness and arrogance. He looked down on this so-called "undead" monster, thinking that it was just some kind of ridiculous experiment, not worthy of his real attention.

Then, he raised his head and chest and shouted towards the closed cage. His voice was loud and powerful, as if it could penetrate this thick cage and reach the outside world.

"I know someone is watching us! Let me go, or I'll make you pay. You can't stand the revenge of a devil fruit ability user!"

His actions immediately attracted the attention of othersThe attention of the death row prisoners was drawn to them. They all turned their heads to look at the strong man, with surprise and admiration in their eyes.

After all, not everyone can be so calm in the face of the humanoid monster not far away.

The "undead" monster also seemed to be angered by the actions of the strong man. The dark green light in its eyes became more blazing, as if two balls of anger were burning in it. It roared and pounced on the strong man.

The bald death row prisoner, with muscles as hard as iron and stone, stood in the chaotic cage, as conspicuous as a lone peak. There was an unyielding light in his eyes, and he was obviously not crushed by the desperate environment. At this moment, he stared at the "undead" monster not far away with a determined look on his face.

Suddenly, the bald death row prisoner shouted loudly, like thunder, shaking the entire cage. He shouted not only to give himself courage, but also to show his determination and courage to other death row prisoners.

Then, he raised his huge fist, and with the sound of whistling wind, he fiercely slammed into the "undead" monster. His fist was as hard as a hammer, and even steel would be deformed under this blow.

However, just when the fist was about to hit the "undead" monster, something unexpected happened. The body of the "undead" monster was as slippery as a loach, twisting at an incredible angle, and cleverly dodged the fatal blow of the bald prisoner.

A trace of astonishment flashed in the eyes of the bald prisoner. He obviously did not expect that the "undead" monster would have such a strange body movement. But he was worthy of being a strong man, and he quickly adjusted his mentality and prepared to launch a more fierce attack.

The bald prisoner took a deep breath, and a ray of determination flashed in his eyes. He suddenly activated a special ability, and his whole body began to flash with dazzling white light, as if countless diamond fragments condensed on his skin.

In a blink of an eye, the whole body of the bald prisoner was covered with a layer of hard diamonds. He became like a dazzling diamond statue, emitting dazzling light. His muscles looked even stronger and more powerful against the backdrop of diamonds, as if they contained infinite power.

He roared, and with the blessing of diamonds all over his body, he rushed towards the "undead" monster. Every time he swung his fists and feet, there was a sharp sound of wind and powerful power. The hardness of diamonds plus the strength of the bald prisoner himself made his attacks extremely sharp and difficult to resist.

Although the "undead" monster also has powerful strength and strange body movements, it seems a little powerless under the diamond attack of the bald prisoner. Its attacks were frequently blocked by the diamond layer, and it could not cause substantial damage to the bald prisoner.

The battle entered a white-hot stage, and the bald prisoner relied on the special ability of diamonds to occupy an overwhelming advantage in the battle. He galloped in the cage like a god of war, and every attack made the "undead" monster feel great pressure.

However, the "undead" monster was not completely powerless. It roared and kept trying to break through the diamond defense of the bald prisoner.

"Haha, it's useless! I'm a diamond fruit ability user!!!"

The tall bald prisoner suppressed the undead, and the undead was bombarded by the diamond arm and kept retreating. Just when the bald man was ready to kill the opponent with one move, a change happened!

Seeing that conventional attacks were ineffective against the diamond body of the bald prisoner, the undead monster suddenly let out a deafening roar, and the whole body began to tremble violently. Then, its right arm twisted and deformed in an incredible way, and the muscles, skin and bones seemed to be reorganized by some mysterious force. In an instant, a huge metal battle axe was formed, replacing the original right arm.

This metal battle axe exuded a cold light, and the axe blade was extremely sharp, as if it could easily split all obstacles. The undead monster wielded the huge battle axe, and with a sharp sound of wind, it slashed at the bald prisoner.

Although the bald prisoner was covered with diamonds, his defense was greatly increased, but he did not dare to be careless in the face of this sudden attack by the giant axe. He clenched his teeth and tensed his muscles, ready to withstand this heavy blow.

Just when the metal battle axe was about to hit the bald prisoner, a dazzling light suddenly burst out from the diamond layer. This light seemed to have some mysterious power, which actually slowed down the speed of the battle axe.

However, despite this, the power of the metal battle axe was still extraordinary. It hit the diamond body of the bald prisoner heavily, making a deafening sound. Although the diamond layer was extremely hard, a crack appeared faintly under this heavy blow.

The bald prisoner only felt a huge force coming through the diamond layer, shaking him fiveAll his internal organs seemed to have shifted. He was secretly horrified, knowing that the strength of this "undead" monster was indeed extraordinary.

"Ah, damn it."

After swallowing the blood, the bald prisoner with a bitter taste in his mouth gritted his teeth and stood up.
