Dressed as His Silly Brother Every Night

[Day and night dual souls + synchronization of two worlds + PlayerUnknown's Battlegrounds] I suffer from a strange disease: I transform into a dying fool every night, and a limp idiot during the day. Until that night, I was choked by that concubine who was like a shadow. He said: "Work for me and I will give you three days to live." Later, I burned down the village in the dark to steal secrets for him, leaving a bone-eroding pain on my right shoulder that was synchronized with another world. He carried me, who was dying, into the wilderness: "From today on, 'he' is dead. Your name is Yan Yue, and my name is Shen Yan." Carrying the blood-stained jade pendant, we walked toward the cannibal world. Little did he know that this jade pendant was the "key" to which all conspiracies pointed. And my modern body is paying for every time I travel through my life. ——This is a life-and-death gamble that spans two realms. We are each other's only bargaining chip and a way out.
