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 became Kong's grandson. All he wanted was to slack off and enjoy life. Until one day, a God of War Training System showed up: “Host, complete your missions at once, grow stronger, and reach the pinnacle of the Marines!” 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 who matter to you!” Luo Tian: “My grandpa will protect me.” System: “Host, you need to...” “Don’t need it.” 【Logical conflict detected. Rebooting...】 【Sign-in System module successfully loaded...】 【Get stronger by breathing System module successfully loaded...】 【Get stronger by sunbathing System module successfully loaded...】 【…】 Luo Tian: “I just want to slack off and lie flat…” 【The Host may not want it, but the System has to give it to him!】 When he casually demonstrated the Finger Pistol's ultimate technique in class, and when he showed off a god-tier Moonwalk in front of Momousagi and stole a kiss, the entire Marine Headquarters exploded: This spoiled brat... had he been pretending all along?! Luo Tian: I really am pretty useless, believe me?
