Chen Bo, an elite warrior who clawed his way out of a mountain of corpses and a sea of blood, is shot and thrown into a river during a mission. When he opens his eyes again, he has stumbled into a bizarre otherworld.
In a dark, damp cave, he is imprisoned by an ugly, human-blood-drinking "Blood Demon." Around him are ancient commoners with numb eyes, regularly drained of their blood.
This body turns out to belong to a royal descendant with the "Pure Yin Physique," whose blood is an incomparable tonic to the Blood Demon.
After narrowly surviving the Blood Demons' infighting, Chen Bo unexpectedly acquires a Merit System.
Armed with a mysterious black blade that can easily slay Blood Demons, he begins to fight back.
He unexpectedly obtains a jade bottle bearing the "hope of the human race."
But danger is never far away: the Blood Demon's overlord is hunting him, his village betrays him, and an even more powerful Blood Demon priestess tries to bewitch him...
In this chaotic age, where human life is cheap, Chen Bo struggles to survive while searching for the secrets of his predecessor's identity.
Can he break free of the Blood Demons' prison by himself? And where will the so-called "hope of the human race" lead him?
When a transmigrator with a System faces an army of Blood Demons running rampant in another world, a battle for the survival of an entire race has only just begun.
With the support of good reviews, I see that everything is pretty good so far and there are no poisonous points. I hope the author can grasp the pace well and don't collapse or write too hard. [Grass has been planted]
