One Piece: Sunbathing from the Start, Getting Strong by Doing Nothing

(Pirates + System + Invincible + Laid-Back)

After dying from overwork, Lin Chen transmigrated into the world of One Piece and became an ordinary boy in Foosha Village, where he awakened the Lie Flat and Sunbathe System!

While others sweat through grueling training and fight over Devil Fruits, all he has to do is bask in the sun to level up automatically and awaken top-tier Haki.

East Blue pirates acting up? One punch takes them out! A Marine Admiral gets in his way? Haki crushes them! Celestial Dragons throwing their weight around? He puts them in their place!

He only wanted to lie flat and grow stronger in peace, but ended up rewriting countless tragedies by accident, saving Robin from a life of misery, keeping Ace alive, taking on the World Government, and sweeping aside the New World's strongest.

From an East Blue beach to the top of the world, Lin Chen basks in the sun on his way to invincibility, becoming the most easygoing legend in the world of pirates!

He wants no power or status, and has no desire to become Pirate King. He only wants to bask in the sun, protect those around him, and live an utterly carefree, invincible life!
