One Piece: I'm the King of Slacking, Yet I'm Too Invincible

[Lighthearted + Funny + Invincible + Three Types of Haki + Devil Fruit + Ancient Weapon] I’m going to be the king of doing absolutely nothing! After dying from overwork, Yun Tian transmigrates into the world of the Pirate King, determined to enjoy life and do nothing. But he’s so invincible that he becomes the center of attention wherever he goes. So he changes his approach: he’ll become the strongest man in the Pirate King’s world, and then no one will dare interfere with his lazy life. From the start, he awakens the Three Types of Haki. He gains several Devil Fruits just by sleeping, and even builds an Ancient Weapon himself, leaving every power trembling with fear. He punches the Three Admirals and kicks the Four Emperors, becomes sworn brothers with the Revolutionary Army, and sits down for tea with the Five Elders. Just how unbelievably satisfying can Yun Tian’s laid-back life get?
