She Professed Herself The Pupil Of The Wiseman (WN) - Chapter 28: Necromancy

Bro, I mean, I'm just a tad handsome, a bit skillful, and slightly crafty, that's all! Why do you all have to make my life difficult? This incessant pestering isn't the answer, is it?What? You'll marry no one else but me? No...you...how could you? Without even asking for my consent?

Hao Yan Che is an immortal and Yuan Gun Gun is a mortal.

A legendary powerhouse of his generation, tired of the bustle of the peak, returned to the ordinary city and started a new life as an ordinary teacher. He wrote the legend in the city.

Magnificent mountains and rivers, the rising powerful ones. Some ancient martial art masters stood at the peak, becoming legendary. Some financial crocodiles rose up in the minuscule places, laughing arrogantly.
