Overall, the story is great and I see a lot of potential for this story. I may not be an author but the way you pieced together the outside world with the protagonist gave a vibe of a vigilante to Kurt. The grammar also wasn't bad, and the introduction of Kurt being lower than an average person but rising to power through memories of an immortal cultivator that was identical to him was fascinating. In conclusion, the story is great and I look forward to reading your novels.
