Genshin Impact: Stealing Powers

When Vincent suddenly finds himself face to face with a Hilichurl, he quickly accepts his fate.

With no vision, no special training, and no skill, he resigns himself to whatever higher powers plucked him from his home and placed him in Genshin Impact.

Then, after a miraculous upset win, he discovers that he isn't totally helpless... He finds that for every enemy he slays, he grows stronger. Not only that, but his enemies' powers seem to become his.

Power system is similar to a cultivation story, mana/aura is used to forge a core and grow stronger, with the added power stealing mechanic.

The tone is slice of life, the main point of the story, beyond the first few chapters, is character interactions. Includes romance.
