When the Blood Demon Immortal King and his followers brought the Blood Ancestor's body back to the small world of Blood Eagle Hall, they thought that the Blood Ancestor was merely a corpse.
Although it was a corpse, it was incredibly hard. Initially, they planned to refine it into a War Puppet. They thought that even their Immortal King's power couldn't destroy this body, and once refined into a War Puppet, it would certainly be a significant trump card for confronting other Immortal Kings.
However, unexpectedly, not long after they brought the Blood Ancestor's "corpse" back, one day, the Blood Ancestor suddenly opened his eyes, and blood tears gushed from them, forming the current Blood Sea of this small world.
