Devil Fruit: Invincible from the Tremor-Tremor Fruit

Kaido took a deep breath, as if he wanted to take all the spiritual energy between heaven and earth into his body. Then, his body began to change subtly. His skin gradually became as hard as iron, and his scales flashed cold light in the moonlight. His eyes became deep and wise, as if he could see the essence of all things in the world. At this moment, Kaido transformed into a dragon man, a perfect form that combines human wisdom and dragon power. His wings spread out, like dark clouds covering the sun, covering the originally bright moonlight, and plunging the entire battlefield into darkness.

"Hot breath!" With a low groan from Kaido, he opened his huge mouth, and a hot flame that was enough to melt steel gushed out of his mouth. The flame was like an angry fire dragon, with the momentum of destroying everything, rushing straight to the position where Tai Kui was. The grass and trees along the way were instantly ignited, turning into a sea of ​​fire, and even the air was roasted and twisted.

However, facing Kaido's attack that was enough to destroy everything, Tai Kui did not choose to escape. His three heads roared at the same time, and his six arms wielded various weapons, colliding fiercely with the blazing flames. Every clash of weapons would burst out dazzling sparks, as if two stars collided in the night sky, releasing dazzling light.

In this thrilling battle, Taikui and Kaido both showed their strongest strengths. Taikui's three heads and six arms seemed to be able to attack in all directions at the same time, making it difficult for Kaido to find a flaw. And Kaido's dragon man form gave him strong defense and attack power. Even Taikui's attack that was enough to tear the space could hardly leave a mark on his scales.

As time went on, the battle between the two became more and more intense. Their figures shuttled through the sea of ​​fire, and every clash would cause a violent explosion, razing the surrounding scenery to the ground. In the sky, dark clouds were dense and thunder roared, as if even the heaven and earth were trembling for this battle.

Aokiji was shocked. He hurried to Mu Bai and asked in a deep voice: "Master Mu Bai, you are too partial. Why did Kaido suddenly become so powerful?"

Leaning against the pickup truck, Mu Bai did not answer, but moved his eyes to Hawkeye, who had never made a move.

Hawkeye, who was carrying the black knife, had sharp eyes. He bent down slightly and replied: "Brother Aokiji, don't be angry. I think Master Mu Bai must have a deep meaning in this arrangement. Perhaps Kaido has also become stronger through extremely special means, such as... the strengthening device that once made Master Mu Bai stronger."

Rarely, Mu Bai nodded in agreement.

"The Golden Crow flames in the form of the Golden Crow constantly temper the body, which also makes Kaido more in line with the current world's power system. Kaido may surpass your power in the future and become my number one general." Mu Bai's words were not reserved at all. It can be said that he spoke directly from his heart. After all, this is the fact.

At present, none of his subordinates in the One Piece world, including the Eternal God Cult believers such as Wang Quandao, can adapt to his god-making device and cannot withstand the burning of the Golden Crow flames except Kaido. Kaido, who belongs to the same mythical beast species and the same flame system, can create a stronger combat power improvement.

And this improvement is also permanent like Mu Bai. More importantly, Kaido's fruit awakening speed has greatly increased in this process. Kaido in the dragon form is not the ultimate product of the current fish-fish fruit blue dragon form. According to Mu Bai's observation, as long as Kaido continues to temper in the god-making device every day, he will be able to awaken the fruit to a new stage in about a year.

Hawkeye was neither happy nor angry, and there was a little fighting spirit in his eyes. He was not afraid of his companions becoming strong, because his supreme ruthless swordsmanship needed someone to be a whetstone, and Kaido was just right.

Aokiji, who was standing by, also noticed the impoliteness. He actually dared to question Lord Mu Bai, which was ridiculous in itself. He immediately knelt down to apologize.

Mu Bai waved his hand to show that it didn't matter.

"Keep watching, how Kaido, whose current strength is close to level 80, forces this sun-level beast to exert more power."
