Super Supportive - ONE HUNDRED THIRTY: Ripples, I

A scientist, Duan Yixin, transmigrated into another world. She possessed the body of a sixteen-year-old girl but had not inherited any of her memories. With a broken marriage engagement and no money in her hand, she only wants to earn money peacefully. It's a pity that fate always plays tricks on people.When she thought she could finally live peacefully, she discovered that this world was not as simple as she thought. The man she rescued was the notorious ruthless general, and the woman who stole her ex-fiancé was the female protagonist of this world.She looked up at the sky and asked, “God, are you kidding me?”A few years later, on their wedding night, she stared at him and said seriously, “General, I'm not your white moonlight.”The man lowered his head and whispered in her ear, “Mhm, you are not my white moonlight, you are my life.”

In an alternate world, a demon disrupts dynasties, harvests souls, and refines a banner of ten thousand souls.Under the heavenly tribulation, his body and soul are destroyed, but the Ten Thousand Souls Banner protects his undying spirit. Unable to possess a body, he's countered instead.A laid-back young man in society, wielding the Ten Thousand Souls Banner, roams the human world.With the Ten Thousand Souls Banner in hand, I refine a Golden Core with good deeds.A slice-of-life story with no ambition for conquest, helping the departed fulfill their wishes, gaining merit to repair the Ten Thousand Souls Banner, and enjoying a laid-back life.

I originally thought this was a world like an ordinary urban novel…Drawing comics by myself, traveling is pretty good.
But tell me, what happened to this magician called “Emiya Kiritsugu” who jumped on my face?
