One Piece: I Just Want to Slack Off, but the System Forces Me to Max Out Every Skill

After transmigrating into the world of One Piece,

Luo Tian becomes Kong's grandson and only wants to slack off and enjoy life.

Until one day,

a God of War training System arrives: "Host, complete your missions immediately, get stronger, and become the Marines' strongest!"

Luo Tian: "Why get stronger? My grandpa is Kong. He's strong enough for both of us."

System: …

System: "Host, you can gain power to protect the people you care about!"

Luo Tian: "My grandpa will protect me."

System: "Host, you need to..."

"I don't."

Luo Tian: "I just want to slack off and lie flat..."

[The Host may not want them, but the System has to give them!]

When he casually points during class and unleashes Finger Pistol's secret technique, and when he performs divine Geppo in front of Momousagi and sneaks in a kiss,

the entire Marine Headquarters is thrown into chaos: That spoiled brat... was he pretending this whole time?!

Luo Tian: "I'm really pretty useless, you believe me, right?"
