Chapter 1: Heaven-Defying Talent

Hearing soft whispers next to his ears, Ace opened his eyes with some effort and saw the warm water surrounding him.

"This, this is..."

Ace wanted to speak but found he couldn't make a sound. Turning his eyes slightly, he was surprised to find that he had been reborn as an unborn baby.

"My child, your father is the Pirate King Gol D. Roger. As his son, you can definitely hold on, right? Soon, in a while, you will be born. Just hold on a little longer."

Waves of gentle whispers reached his ears, shocking Ace's heart. One Piece Gol D. Roger? The world of One Piece? Had he transmigrated and become Ace, who shared the same name as him in his previous life? Then the person whispering now must be his mother, Portgas D. Rouge.

To avoid the Marines hunting for Roger's bloodline, Rouge, who was supposed to be pregnant for ten months, held on for twenty months and finally died of dystocia. No wonder he was already mature but not yet born. Had he become Fire Fist Ace of the One Piece world?

Ace thought silently, recalling Ace's life. With the Logia Mera-mera Fruit ability, he inherently possessed Conqueror's Haki and had the potential to become the king of this sea. But because he hated the bloodline of his biological father, Gol D. Roger, he suppressed his top power in the sea.

Finally, in the Summit War, he died under Akainu's magma fist. All he could say was lamentation. Ace's Mera-mera Fruit ability had initially surprised many people in his previous life. Unfortunately, with the subsequent development of the pirate world, it became common for individuals to use fire abilities. The originally super-powerful Logia fruit had become a fruit that even dogs would not eat.

Coupled with his slightly naive thinking, he suppressed his Conqueror's Haki and didn't have a king's heart. His final defeat was inevitable. Speaking of fire power, the strongest one should be Yamamoto Genryusai Shigekuni, the captain of Gotei 13 in the World of Bleach. The strongest flame temperature he could use was comparable to the core of the sun, He was known as the strongest Shinigami in a thousand years

Especially in the battle with Aizen, even if Zanpakutō Ryūjin Jakka was sealed, he could still use Hadō 96's One-Sword Cremation. That flaming blade rising into the sky is true fire. Ace thought silently.

"Call!"

While thinking this, Ace felt his eyes darken. The next second, the surrounding environment changed from a warm ocean to a city in ruins. He found himself in a deep pit of ruins.

"I will not tell you to keep your life. After all, your life is the history of Seireitei, Yamamoto Genryusai. Your destiny is to die by my sword."

A cold, inhuman voice reached Ace's ears. He raised his head with effort and saw a man in white walking towards him with a sword.

"Aizen?!"

The familiar face and outfit shocked Ace. As Aizen approached, Ace's right hand instinctively grabbed Aizen's foot.

"Kid, don't make me repeat myself again."

An old but energetic voice came from Ace's mouth. Dark red cracks began to appear on his burnt arm. Aizen's eyes trembled slightly.

"This, this is the Forbidden Technique driven by my own burnt body. Sacrifice No. 96 Hadō-"

Aizen's pupils shrank suddenly.

"Itto-Kaso!!!"

"Boom! Clang!"

With an angry roar, endless flames rolled out from the charred remains. The terrifying flames instantly gathered into a fire blade rising into the sky. The brutal and terrifying temperature made the atmosphere distort and break. Everything seemed to be swallowed by the high temperature. The fire blade rising into the sky, piercing the entire sky, symbolized the strongest flame king in this world.

"Call!"

The next second, the screen shattered, and Ace returned to the familiar warm ocean.

"Your understanding is heaven-defying. Through visualization, you can understand it personally and derive your exclusive skill - cremation with one knife!"

"Your heaven-defying understanding, through the whispers of Portgas D. Rouge, has completely mastered the world language of 'One Piece.'"

Instinctively, the information that suddenly appeared in his mind shocked Ace.
