Lin Yu transmigrates into the world of a novel and becomes the villain, destined to be humiliated by the protagonist, killed, and robbed of his wife.
Once he figures out his situation, Lin Yu panics and immediately considers disemboweling himself. Better to die early and be reborn sooner.
Fortunately,
he has nine stunningly beautiful and powerful masters. By the later stages of the story, every one of them will become a female emperor.
Lin Yu awakens the Ten-Thousandfold Critical Return System. Whenever he receives a gift from one of his masters, there is a chance it will trigger a ten-thousandfold return.
[Ding! Received a top-grade Spirit-Gathering Jade Pendant from Little Master (Ying Yaoyao). Ten-thousandfold critical return triggered: Everlasting Desolation Cauldron]
[Ding! Received a Heaven-tier martial skill, the Dustless Sword Art, from Seventh Master (Ye Ningshuang). Ten-thousandfold critical return triggered: Everlasting Desolation Art]
When Lin Yu finally grows powerful enough and decides to take revenge on the protagonist,
his nine masters step forward instead.
Little Master (Ying Yaoyao): “What? Someone dares bully my little Yu? He must be tired of living!”
Seventh Master (Ye Ningshuang): “Little Junior Sister, don’t fight me for this. The honor of killing the enemy who wronged Little Yu belongs to me!”
Second Master (An Miaoyin): “Stop arguing, all of you. I’m a female emperor, so let me go first!”
Lin Yu: “...”
“Masters, do you really have to spoil me this much?!”
It's okay, and it gives some encouragement to the harem theme.
