I Was Promised That Being a Simp Would Boost My Cultivation, Not Land Me in a Love Triangle

[One Male Lead + Male Lead Has No Past Relationships, Female Lead Does + Simp System + Rivalry Between Men + Transmigrate into a Book + Cultivation + Happy Ending]

Su Yue transmigrates into the book as a disposable supporting heroine and gets bound to a Simp System.

The System says that fawning over handsome men will boost her cultivation, but it never said it would lead to a battlefield of romantic rivals!

The Snake King has eyes only for her. The Demon Palace Master sees her as his salvation. Even the aloof Holy Son of the Medicine King Valley asks, eyes reddening,

“Is there anything they can give you that I cannot?”

Su Yue trembles.

“Um... I'm really only here to cultivate properly... Just kidding...”

A word of caution: The heroine is quite flighty at first, but later she only loves one man.
