Traveling to the world of One Piece, Lingdu can become stronger by binding food delivery to the system
As long as the food made by himself is delivered to the strong person and the other person eats it, he can copy one of the other person's abilities. Delivering ramen noodles to "Pluto" Rayleigh, he learned armed domineering; delivering rice balls to the sea king class, he gained great strength; delivering fried rice to pirate hunters, he awakened his hunting instinct.
From a handyman in the Chambord Islands to a delivery boy who broke into the war on the top, Lingdu's orders became more and more outrageous: delivering oden to Whitebeard, rice balls to Luffy, wine to Kaido... The navy hunted him, the Yonko wooed him, and Blackbeard offered a reward of one billion to capture him alive.
Ling Du just wants to deliver every order on time. But when he stood at the finish line of Ravdru, Luffy asked him how he became stronger, and he silently opened the incubator: "Hello, you have a copy of 'The Strongest' to be signed for."
