Villain: The Protagonist's Mother Is Actually in My Harem

Gu Zhi transmigrated into a book and arrived in a martial arts world, where he was a villain and had gotten the mother of the protagonist, Long Aotian, pregnant with his child.

Then along came a shady System that wanted him to become a cuckold-maker.

Gu Zhi: "From now on, we'll keep our relationships separate. I'll call you little brother, and you call me Dad!"

Long Aotian: "I'll kill you!!"

Ye Liuyi: "Aotian! Don't treat your Uncle Gu like that!"

System: "All the chosen ones of fortune in the original world are your children."
