One Piece: My First Companion Is Jerry

Zhong Lu is tricked into picking up a package for the campus beauty, then transmigrates to the world of One Piece.

His first crewmate is Jerry, who serves as the first mate and cook.

Zhong Lu also obtains the “Negative Emotion Value Laboratory.”

He can summon new crewmates by spending emotion points.

When his crewmates stir up trouble, they can collect negative emotion points.

The more crewmates he already has, the more emotion points it takes to summon another.

His second crewmate is Elsa, who serves as the helmsman.

His third crewmate is Bumblebee, who serves as navigator and a temporary means of transport.

His third crewmate is Grey Wolf, a master inventor and shipwright.

His fourth crewmate is Qin Shiyue, who serves as an assassin and intelligence officer.

His fifth crewmate is Son Gohan, a scholar in charge of research.

Zhong Lu's own cultivation is too slow, but he can spend negative emotion points to copy his crewmates' abilities.

Negative emotion points can be used to summon crewmates, but if they aren't replenished, they will dwindle. Once they reach zero, the crewmate disappears, and the points spent to summon them are refunded.

Once all the crewmates disappear, the protagonist begins to rot until he dies.
