In his previous life, Kang Bo was the all-powerful god of war in the underworld, but he failed due to various regrets. After his rebirth, he just wanted to be an ordinary dad and protect his family. However, the underworld forces in the dark are afraid of his past and keep attacking his family, trying to break this tranquility. If he cannot dismantle the complex forces of the underworld in a short time, his family will lose peace and happiness. Due to his emotional weakness, his decision-making was greatly affected when faced with threats from the underworld. At the same time, his family has misunderstandings about his past as a mafia god of war, and the swing characters around him may be used by the mafia to betray him, causing a crisis of trust. Under the time limit when his family may be in danger at any time, Kangbo relies on his rebirth advantage and the strength of the God of War to launch a fierce confrontation with the underworld. Although he succeeded in defeating the underworld forces in the end, his family was injured in the process, and the victory was accompanied by bitterness.
