One Piece: From Stranded on a Desert Island to King of the World

After working himself to death at a 996 job, Lin En transmigrates into the perilous world of the Pirate King, starting from the start on a deserted island, with his body shrunk to the age of sixteen! Just as he is on the verge of despair, a monstrous Lord of the Coast bursts out of the water, instantly making him realize that this is where Straw Hat Luffy sets sail! He worked himself to death in his previous life. Should he spend this one lazing around, too? No! He's had enough! “Ding! Your [Punching] proficiency has increased by 1!” A crude interface appears before his eyes. It has no intelligence, no quests, just cold, impersonal numbers. Yet Lin En is overjoyed: this is his greatest trump card! Abandoning wishful thinking and committing himself to absolute discipline, he will max out the basics on this deserted island! After a million punches, his fists can split stone! After ten million sword swings, his sword energy can cleave the sea! When vicious pirates land on the deserted island, thinking he's a lamb waiting for slaughter, he blasts them to pieces with a single punch! “What? That monster who punched a hole through our ship is just a boy who's never even gone out to sea?” Leaving the deserted island is only the beginning. In Shimotsuki Village, his understanding of swordsmanship, surpassing even Koshiro's, astonishes everyone. In the East Blue, he single-handedly levels Arlong Park and saves the Nami sisters. On the Grand Line, he even topples the Shichibukai from their thrones! Fleet Admiral Sengoku: “His rate of growth defies all common sense. He must be eliminated immediately!” Kaido of the Four Emperors: “Madman! That man is even more of a monster than I am!” Wielding a supreme Great Grade Sword and setting foot in the Celestial Dragons' holy land, Lin En looks around at the World Government prostrate before him. “I came, I saw, I conquered. From now on, I am the only rule in this world!”
