On a rainy night, my sister Lin Xue fell in a pool of blood, clutching Lin Jin's college admission letter and leaving her last words: "Brother, don't become like them..." At that moment, Lin Jin, a former top student, burned his bright future with his own hands and fell into the abyss. He vowed to burn out all evil in Tianhai City. To this end, he did not hesitate to transform into Shura and fight violence with violence.
He gathered the ruthless Lei Bao who carried the last wishes of his comrades, and Han Ying, a genius hacker who did not hesitate to break the rules in order to find his relatives. This team that walks on the edge of the knife established an order called "Cinder City" in the Dark Empire. However, the road to revenge is full of tests of human nature: Forensic doctor Xia Wan understands his goal but resists his methods, becoming a glimmer of warmth in his cold heart; the unexpected appearance of his innocent cousin Su Xiao becomes his weakness that must hide the blood and protect the last kindness.
When Lin Jin stood at the pinnacle of power, what stared at him were not only the covetous enemies, but also the fire of karma he had lit with his own hands. In the whirlpool of love and justice, crime and punishment, can he fulfill his promise to his dead sister, not get lost in revenge, and finally bring true new life to the city? This is a dark heroic epic about revenge, protection and redemption, exploring how the light of humanity can set a prairie fire in the darkest moments.
