Start of the Blood Tribe: Hancock and I Rule the Sea

[Protagonist vampire + fantasy beast species + multiple identities + Hancock + farming + western fantasy] After traveling through time twice, Yaze, who had already traveled to become a vampire, once again traveled to the world of pirates and met Empress Hancock before awakening to the [Empress Development Plan System]. Any behavior that is helpful to Hancock will be rewarded by the system. Later, Yaze ate the phantom beast species, Frost Fruit, and Frozen End form that were rewarded by the system, and then went to the Navy to serve as Hancock's internal agent. He also used his other mysterious identity [Night Shadow Lord] to sabotage the World Government's plan. First the Shichibukai, then the Four Emperors, and then a new regime was established in the second half of the Grand Line to annex the World Government's sphere of influence. Wulao Xing: "I was only busy dealing with the Revolutionary Army and Night Shadow Lord, but I didn't expect Boya Hancock to grow to such an extent." Warring States: "The abominable Boya Hancock actually quit the Shichibukai! Yaze, I appoint you as the Ice Dragon General, responsible for hunting down Ye Shadow Lord and Boya Hancock!" Yaze: "What? Am I hunting myself and my wife?" A few years later, Yaze and Hancock completely overthrew the decadent and backward Tianlong government and established a prosperous regime of universal unity!
