Synopsis

[Swordsmanship Grindset + Yandere Training + Muzan’s New Dad (Low-Rating Protection)]

Xu Lin transmigrates into the Kocho family as their frail adopted son, and only wants to protect the Kocho Sisters in peace.

But as he keeps protecting them, both girls turn into yanderes!

“Darling, wouldn’t it be better if you just did as I say?”

“Big brother, why were you smiling at that girl just now?”

“Lin, you only need to look at us forever, okay~”

A chill runs down Xu Lin’s back. To avoid getting hacked to pieces, he can only grit his teeth and grind:

He grinds the [Swordsman] skill up to [Swordmaster], bringing his swordsmanship on par with Yoriichi.

He grinds his [Normal] physique up to [Transcendent], making his body tougher than the Demon King’s.

Years later, he opens the Infinity Castle with his sword all alone, takes down [The Unwidowed Muzan], and secures a perfect ending with no sacrifices.

Before he can even catch his breath, he hears a cleaver scrape across the floor behind him.

The Kocho Sisters smile sweetly: “Honey~ Would you rather have sushi first, take a bath first, or eat me first?”

Xu Lin: “Wait! Calm down!”

Xu Lin: “Nezuko, Mitsuri... help me!”

The girls exchange smiles, the unhealthy grins at the corners of their lips growing ever wider.

"Demon Slayer: What Should I Do Now That I’ve Protected All the Heroines Into Yanderes?"

This… a lingering romance?! Akaza and the Third Brother are actually rekindling their past? That's amazing! So how is Muzan going to play this game in the end? The Third Brother, who started out with a love-struck mind, has completely rebelled! (Can accept couples working together.) —IP: Infinite Castle. Muzan: Third Brother, if you had said you liked this type earlier, I could have transformed!

"However, Xu Lin didn't notice that in the shadows of a collapsed wall outside the dojo, a pair of eyes, their pupils constricted with extreme fear, were fixed on his departing figure until he completely disappeared into the darkness." (Classic example of "buried poison")

Chapter 81 should have shown Nianxue and Upper Moon Three disappearing together after their reunion. Unexpectedly, a demon even joined his team. No regrets, they met and left together—what a perfect ending! No matter how you try to whitewash it, how many people did he kill and how much did he eat in those 300 years?

If you're looking for pure wish fulfillment, this is a bad read. The protagonist is surrounded by Upper Moon demons, turned into a demon by Muzan, and then captured with the female lead. To avoid hurting her, the protagonist self-harms and falls into a coma, after which the female lead commits suicide.

Excellent, a good book, highly recommended. You like to subject people to extreme torture and suffer from writer's block, right?
