One Piece: God-Tier Big Boss

Chen Jian transmigrates to the world of One Piece with the "God-Tier Big BOSS System," becoming Portgas D. Ace's cousin. His life is about to get awesome.

"Ding! Congratulations, Host, you've received a Supreme Starter Pack containing Hyorinmaru, Ryujin Jakka, and the Gold-Gold Fruit."

Fire Fist Ace: "Cousin, help! Blackbeard is trying to kill me!" Chen Jian: "Don't worry, cuz! I'll beat him to a pulp!" "Ahhh... Oh... Mm..." Blackbeard is dead.

"Ding! Congratulations, you've unlocked a Crystal Summoning Card and received one card. The card randomly summons Kaguya Otsutsuki, who can fight for you once for a duration of one minute."

Frost blankets the earth, flames scorch the sky. Ice and fire together make him invincible under heaven.

"Life is as lonely as snow!" Chen Jian says, showing off without restraint, holding Great Crimson Hyorinmaru in his left hand and Ryujin Jakka in his right.
