I think I read this novel

I remember there being about 70 chapters of the novel, but I don't remember the title. I know it was different from the one used here. There are some slight differences and details between the manhwa and the novel. I wanted to reread it again, but I couldn't find the novel, do you remember the name, pls?(づ￣ ³￣)づ

Hermit wizard

And I don't remember the mc having white hair or red eyes

Thanks!
Yes, they changed some things. The MC's name and appearance, the entity in the doll are different. There is no scene of him being beaten and bullied as a child. The seeker is called the seekers of truth. Those scenes of him entering portals to hunt for ingredients to sell potions also do not exist in the novel. They tried to make it more commercial and left it more generic, I found it weak compared to the novel. I don't even know if this was authorized by the author or if they plagiarized his ideas. I'm almost certain that this is plagiarism, that's why they changed so many small details. (╯°Д °)╯╧╧
