Long Yi only wants to be an ordinary student. But on his first day of school, he protects his bullied roommate by punching out three of the campus bully's teeth. He thinks it's just a minor schoolyard scuffle, unaware that the punch has broken the seal on the secret of his birth, hidden for seventeen years: he is the only son of the missing Dragon King, the underground emperor of Jiangcheng.
His peaceful school life comes to an abrupt end. The gang behind the bully, a drug-trafficking network embedded in the campus, and a blood-red envelope handed to him by a mysterious transfer student all drag him into the whirlpool of the underworld. Caught between his identities as a student and an heir, Long Yi must establish order with his fists and navigate the worlds of light and darkness with his wits. Amid brotherhood and betrayal, he searches for a way to survive.
When he finally stands before the blood-red throne his father left behind, he discovers that the real struggle has only just begun...
