MTL - Plane Development Plan - ~ Fanwai Seven: Become a Buddha without Heaven and Earth

Enemy of the world, cursed by all, Kim Sungchul goes on a quest to prevent the ‘prophecy of the end’ from coming to pass.

But no matter how much he raised his strength, there were still some things he could not achieve with physical strength alone.

Resolving to obtain the power of magic, he goes into hiding to learn magic from his most hated of enemies, The Mages.

These days, could one really time-travel just by dreaming? And to become a silly princess at that. Well, marrying a domineering man wasn't too bad. His taking a concubine wasn't the end of the world either. But why was she forbidden from liking anything except him? That was just too domineering! She had to escape! Ah, but upon escaping, she realized he was a half-demon who didn't understand love... and, moreover, a half-demon who had a three-lives connection with her...

A lonely soul, which was placed under the care of the Lord Protector’s Manor, ended up having her lover stolen by the family’s eldest daughter and dying tragically the day before her wedding.

Somehow, she was reborn in the family as their 14-year-old first wife’s daughter, Ning Xueyan, with a startlingly familiar face.

Step by step, she will ruthlessly scheme to seek revenge as well as uncover the mystery of her tragic death.

Her former fiancee, the flirty crown prince and the bloodthirsty prince, will now bear witness to a vengeful Ning Xueyan becoming the peerless lady of her generation…

What the hell is this? What the hell happened here?
