You Were Supposed to Manage the Straw Hat Crew, So Why Did Their Strength Double?

Lin Cheng transmigrated into the world of One Piece and became a core member of the Straw Hat Pirates, while activating the Super God Manga System.

Knowing how the Summit War would end, Lin Cheng advised Luffy to find Rayleigh and train for a while before the war began.

When Luffy returned, he was completely stunned!

Sanji: "Eighth Gate, open! Taste my Night Sanji!"

Zoro: "Sun Breathing, Eleventh Form: Dragon Sun Halo, Head Dance!!!"

Usopp: "This Thor's hammer is way better than my slingshot. I can hit things with it or throw it!"

Chopper: "The Rinnegan is incredible. Feel the power of a god: Monster Point Susanoo!!!"

Luffy: "I asked you to manage the Straw Hats, and you actually raised their strength to the level of the Pirate King?!"
