What happens when Spider-man gets the ability of Ito Ito No Mi fruit and understand Haki??
What happens when Hulk gets the Rubber Devil fruit and learned Armament Haki??
Ironman: Lin, give me a devil fruit, I am willing to exchange it with 30% of Stark Industries shares.
Lin Yei: I give you the Gold Devil Fruit but the price is 40% of share.
Of course, Lin Yei is not a saint, every time he provides a devil fruit to someone, he also becomes powerful.
