I Transmigrated into the Protagonist's Villainous Adoptive Father

[Younger love interest + two male leads + raising him + foster-father romance]

A seemingly carefree but fiercely survival-minded bottom ✖ an attack who seems like a beacon of righteousness but is secretly turning evil

Modern-day lawyer Qi Su was run over by a truck in the middle of the road after his enemy took revenge on him. When he woke up again, he found himself inside a novel!

His new identity was that of a character who shared his name, a villain who had taken the protagonist in in the story.

Qi Su looked at his frail body, then at the small, skinny protagonist cooking for him nearby, and immediately felt his whole world collapse.

This had to be a nightmare!

Qi Su devoted himself to currying favor with the protagonist, hoping he would spare his life one day.

He planned to see the story through and then say goodbye. But the kid just kept growing, and when it was finally time for Qi Su to follow the plot, he ruthlessly crippled the little pup's cultivation and threw him into the Abyssal Domain, just as the original novel described.

He thought he could simply wait two hundred years for the protagonist to follow the plot and kill him, then find a new body and enjoy life.

But before even a hundred years had passed, the demon clan invaded, and Qi Su was forced onto the battlefield. As the two armies faced off, he saw the little pup he had cast into the Abyssal Domain!

Wait a second, how had the protagonist turned into a villain?!

The protagonist's characterization had gone completely off the rails. Si Yan imprisoned Qi Su in his palace, then pulled the little pup he had raised himself into his arms and whispered in his ear, “Foster Father, do you know what these past hundred years have been like for me?”

Thanks, but he really didn't want to know!

Where had his guide to raising a kid gone wrong?
