The Rise of a Despot (слэш)

Moments before his death, Wen RuoHan triggers a transport talisman and his soul is brought five years back to his past. As he thinks about how he could have accidentally made this magic happened, he forms a theory that his qi had mixed with the qi's of the two young cultivators (barely twenty years old) who attacked him. The talisman was soaked in his blood and when he activated it, the mixed energies were so powerful, his soul was thrown five years back. He becomes obsessed with wanting to own Lan WangJi and Wei WuXian because he believes that they are the key to him reaching immortality.
Or Wen RuoHan shows his romantic and tender sides to WangXian, using their love for each other to woo them into his embrace.
