Chen Mu, the concubine of the Chen family in Qinghe, was taken as a hostage at the age of seven and abandoned by his family at the age of eighteen. When the night of the resurgence of spookiness fell, the city switched to a world of hidden rules, and he died for the first time in the "Night Trial". At the moment of death, he saw the countdown to his return. Opening his eyes again, Chen Mu returned to three hours ago. He memorized every fatal rule in the Night Realm - which road would devour a living person, which words would trigger a cunning contract, and which tribesman would stab him in the back. The third time he died, he discovered that turning back would consume his memory and longevity. The fourth time, he killed his legitimate son Chen Yan in the Shura field. The fifth time, he forced Shen Qingshang, the eldest daughter of the Shen family, to sign an unequal night contract. For the sixth time, he came across the shocking secret behind the family's nightly rules - Mrs. Chen's succession war was never about choosing a successor, but about making sacrifices. There is only one last chance to turn back. Chen Mu stood in front of the Chen family's ancestral hall in Qinghe, holding the price of seven lives in his hands. Tonight, he wants all those who have abandoned him to kneel down and see clearly - the knees of a discardable person cannot kneel down.
