Zhang Chen is an orphan whose life has been full of hardship. After unexpectedly inheriting the estate of his mysterious great-uncle, he is brutally murdered. After death, his soul remains, and he watches his ex-girlfriend Li Xinya and the rich playboy Wang Hao search his corpse, desperate to take the "Supreme Black Card" that unlocks his vast inheritance.
On the verge of vanishing, Zhang Chen is bound to the "Soul Revenge System" and gains ghostly abilities. He vows to make those who harmed him pay in blood. But as his revenge deepens, he discovers that he has become entangled in a conspiracy far more terrifying than a personal feud. The black card is no ordinary inheritance: it is a vessel sealing the ancient evil spirit known as the "Soul Devourer," and he is the last chosen guardian.
Even more shocking, Chen Yan, the morgue doctor, is his long-lost twin brother. They share the same "Guardian bloodline." One is a spirit, the other alive, but fate brings them together again to fight the dark forces seeking to gather all seven black cards and release the Soul Devourer.
Revenge and redemption, soul and body, bloodline and destiny: Zhang Chen must complete his revenge and master the black card's power within seven days, or vanish forever. Yet as he gradually uncovers the truth, he discovers that even the "System" has a hidden purpose...
In this battle that crosses the boundary between life and death, the living are not necessarily innocent, and the dead are not necessarily evil.
Will you dare to face the darkness deep within your soul?
