I'm very happy to recommend the novel "Comic Series: Starting from the King of the Undead". The main character's surname is Lin. It's a light novel-derivative doujinshi novel. The novel told the story of the protagonist crossing into a strange world, escaping with his golden finger, and fighting against the Bone King. The main character, Lin, was one of his superpowers. I hope you like this fairy's recommendation. Muah ~😗
