MTL - The Little Merman - Chapter 55

Xiao Yi, an orphan raised by a disrespectful old man, possessed mysterious ancient martial arts and a unique skill in traditional Chinese medicine. At the age of twenty, he suddenly received the most baffling mission from the old man: to attend the renowned first-tier university, University Z, as a student, initiating his spectacular modern urban life. In the city, he began to write his own eternal legend...

A failed investor from 2017 got drunk and woke up in the 1980s. China is just opening up, and the economy is blooming. There is also the dissolution of the Soviet Union, the bursting of the Dot-com bubble and other financial crisis. He used his knowledge of the future and slowly build up his empire.

Birth of the Biomancer:Mio was the worst healer in Tokyo. F-grade, dead weight—her party kept her around out of pity until they did the math and left her bleeding in a ruined cathedral.Something ancient was waiting there. It offered her a Class that devours its hosts—a path of power that claimed the lives of the three Biomancers who came before her. Mio said yes anyway. She’d already felt the sting of a slow death; what was one more monster in her veins?Now pain is currency, death is fuel, and the hunger grows with every kill. The Bureau wants a weapon. Her sister wants her home for dinner. Mio agreed to both.In a world of Systems and Dungeons, power isn't a gift; it's a trade. And Mio is finally ready to pay the price.════════════════════What This Is:[1] This is a progression fantasy with system elements, but the system serves the story, not the other way around. Expect meaningful numbers, not stat spam.[2] Romance is not the focus. Mio has bigger problems. But expect a slow-burn later down the line![3] The story gets dark, but it's earned. No grimdark for shock value.

The constant mission is getting redemption.

Shuttle though various worlds to become a variety of scum men, do a little whitewashing and become a good man in the eyes of everyone.

Redeem those who are miserable, and let them live a happy life.
