Three years ago, "Night Owl" Jiang Xiaohua, the top assassin of the supernatural organization "Dark Trace", defected from the organization for his true love Liu Ruyan, but was betrayed by him. He was besieged by twelve top psychics and fell into an abyss. Everyone thought he was dead, including the woman who pushed him into hell with her own hands.
Three years later, a crazy scavenger appeared in Jiangcheng. His clothes were ragged, and his eyes were sometimes dull and sometimes flashing with a chilling light. No one knew that this sick young man known as "Crazy Chiang" was the Night Owl who made the entire underground world fearful.
Jiang Xiaohua is not dead, but there is something wrong with his brain. During the three years under the abyss, the extreme environment and brain trauma caused him to suffer from severe paranoid schizophrenia. He couldn't distinguish between reality and hallucination, and his memory was fragmented. However, he was a blessing in disguise and awakened an even weirder spiritual power - he could infect his "disease" to others.
When former enemies appeared one after another, and when Liu Ruyan appeared in front of him with her secret lover on her arm and now the new leader of "Dark Mark", the strings in Jiang Xiaohua's mind were completely broken. Sometimes he is awake, planning the cruelest revenge; sometimes he is crazy, using the sickest and most unpredictable ways to drag powerful superpowers into their own deepest fear and madness. This is not the returning king, this is the returning nightmare.
