Loidine's manga / #Cultivation(24)

Childhood friends/rivals to lovers. Working with each other even though they're on different sides of the war.

MC is a shizun. Powerful. Talented. ML is the demon prince. Sneaked to the human realm to train and became a disciple. MC transmigated in a danmei novel where the protagonist gong sexually abuses his shizun (protagonist shou and a big softie). MC possessed the body of said shizun, and is definitely not willing to undergo the same fate as the protagonist shou, so he is trying to manipulate the flow of the story to prevent him accepting the ML as his disciple.

Shizun (192yrs old) x transmigator (175yrs old) ML is sooo adorable, he is INLOVE with MC and very jealous of himself cause kind of have a second personality, forgetting whenever he switches. MC is an omega in his past life that transmigated to another world as a supporting character.
