Marineford: I Merged with Black Dragon Tian and Left Whitebeard Stunned

Shen Fei transmigrates to the world of One Piece and activates the Strongest Faction Creation System!

He can draw templates for factions from across the heavens. As long as he makes the factions he draws famous, he can earn all kinds of rewards.

Once a faction's name resounds across the seas, he can even summon the entire faction into this world!

Starting with the Summit War, the Seven Shadow Assassins stand tall in the sky, looking down upon the Navy and the Whitebeard Pirates, and the sea!

Heilong Tian leads the Divine Clan in an assault on the Holy Land, exterminating the Celestial Dragons and forging the Divine Clan's reputation!

The Akatsuki Organization descends upon Wano and wipes out the Beast Pirates with a flip of its hand!

Sengoku: "I've been Marshal of Navy Headquarters for all these years, yet I never knew there was such a dangerous organization as the League of Assassins on the sea!"

Imu: "Even I have never heard of this Divine Clan. Could it be that they have existed even longer than I have?"

As Shen Fei creates one faction after another from outside this world and brings them here,

everyone across the entire sea is left utterly stunned...
