[One Piece] + [forming a crew] + [System] + [achievement rewards] + [two Devil Fruits] + [swordsmanship] + [invincible]
Chen Kai, better known as Young Master Kai, somehow transmigrated into the world of One Piece and obtained the all-purpose Death God System. He entered a life-or-death challenge called the "Brave Game."
I'll decide what it means to be the strongest:
The strongest dual Devil Fruit user, the strongest mastery of all three types of Haki, the strongest swordsmanship, the strongest crew. Not strong enough?
World, feel the pain.
This will be the greatest celebration of all. The crew is assembling, and an invincible legend begins in those mysterious seas!
