Klin who fought soy sauce was actually the strongest earthling, and the world of Dragon Ball was a world where earthlings fought soy sauce and Saiyans were invincible.
Modern people who only understand the domestic family boxing theory in China, but have not really learned Tai Chi, Bagua, Xingyi, etc., are reborn in the Dragon Ball world they like.
Without the talent of the Saiyans, without the magic of the Nameks, he is an ordinary earth person who even has no talent even one percent of Klin.
He first learned the martial arts of the Dragon Ball World. He learned the Crane Immortal Stream. After the integration, he combined the martial arts of the Dragon Ball World with the previous life Neijiaquan theory to create his own martial arts.
This is the strongest story of a man on earth.
