Overthrowing the World, Starting from Impel Down

Zhuo Jun transmigrates to the world of One Piece and becomes a prison guard at Impel Down. By chance, he obtains a God-Tier sign-in System and the devouring ability it grants him.

From then on, the once-powerful prisoners of Impel Down become experience points for his growth.

He masters the swordsmanship of a great swordsman, all three types of advanced Haki, and the Six Powers of the Navy.

Zhuo Jun rises to power in Impel Down.

After going out to sea, he crushes the Seven Warlords, beats the three Admirals to a pulp, and forces the Four Emperors into submission, becoming the emperor of the sea.

In the end, he storms the Holy Land of Mary Geoise to face Imu.
