MTL - Great Voyage: Invincible From the Era of Rocks - Chapter 347

Year 2056, in a city in the Yuan Jiang Su Jin area. On top of a ruined, shattered six story residential apartment sits a teenager wearing a combat vest, militaristic trousers, and alloyed battle boots. On his back is a hexagonal shield and equipped is a blood-shadow battle knife. He sits there silently on the edge of the roof. At this time, the sparkling sky was shining and there was a refreshing breath within the air that blew towards him. However, there was only silence within the ruined, deserted city, with an occasional howl that makes your heart skip a beat.

In the Canglan Continent, there existed a rule: only those who managed to awaken a Martial Spirit were able to pursue the path of cultivation, and a Martial Spirit’s rank was determined when it was awakened. Born in Linshui City, Qin Nan was a peerless genius who possessed great talents and was highly anticipated to become a great cultivator in the future. However, things changed when he ended up awakening the lowest-grade Martial Spirit, resulting in him being considered trash.

Crossing to One Piece world, he became Roger’s younger brother.

Unexpectedly, Gol-D-Roger who was in his fifties had a teenage brother. But he was so weak.

Fortunately, at the age of sixteen, he actually found himself with a possession soul system.

He had attached to the master IP man, also to the White Phoenix and to Ge Nie with his strong ability of the Hundred Step Flying Sword.

If you think that he can only Purchase these? Then you’re wrong!

Pain, Itachi, Ichigo Kurosaki, as long as there is money, any soul can be Purchased.
