[Invincible + Decisive in killing + Fruit development + Original plot + No heroine + Do whatever you want + Principled, please be careful] Chenfeng traveled through the pirate world, and his understanding at the beginning was incredible. Touch the corpse to learn corpse fighting techniques. By touching the corpse of a person with devil fruit abilities or a person with dying abilities, you can realize the fruit's abilities without any side effects. A year later, Chen Feng became invincible in the world and was nicknamed the God of Death. Feeling bored, he planned to enter the new world. He came to the naval base - Shieldstown. Encountered Roronoa Zoro and Luffy who were captured by chance. At this time, an accident happened and Mengka targeted Chenfeng. Mengka threatened Chen Feng, but was killed by Chen Feng. Finally, Chenfeng was invited by Luffy. He wanted to refuse, but then he changed his mind. He was going to the new world anyway, and it might be more interesting to take Straw Hat Luffy with him. Chenfeng joins the Straw Hats and becomes the vice-captain. So the new Straw Hat was established, Luffy: legal representative. Chenfeng: the boss behind the scenes Luffy: Vice-captain, why do you have so many fruit abilities? Chen Feng captured one of the three major weapons, "Pluto", and successfully built Pluto. As for the three major weapons of the Sea King, Chen Feng also understood its ability to control the Sea King beast? No, he can even control all sea creatures. He has become the master of the ocean. As for the history of 800 years ago, Chen Feng doesn't care at all. If he wants to, the current world government will become history.
