I Transmigrated into One Piece, but Somehow I Don't Have Conqueror's Haki

He transmigrates into One Piece. Others awaken Conqueror's Haki from the start and awe everyone around them.

Xiaolin transmigrates as an ordinary East Blue citizen. The first line of his System's scan reads:

Conqueror's Haki aptitude: permanently absent.

Luckily, he binds himself to a training-makes-you-stronger System. One hour of training for him is worth five hours for anyone else. Train five hours a day, and that's the equivalent of an ordinary person cultivating hard for a full day!

Pirates are killing and looting? His life comes first, so he decisively latches onto the Navy's biggest thigh.

When Iron Fist Garp patrols the East Blue, Lin Mo shamelessly approaches him:

"Vice Admiral, need someone to carry your rice crackers? I'm happy to haul cargo or run errands!"

Starting as a menial aboard a warship, he develops at a frantic pace with five times the efficiency.

No Conqueror's Haki?

Then he'll train Armament Haki to the level of cell destruction, and project Ryuo to break defenses from a distance!

He'll train Observation Haki to foresee the future in multiple layers and perceive everything across the whole area!
