Kiikuro_Shichigo the reason why when you typed in Isekai and didn’t show any novels is because Isekai is a Japanese term, this is a Chinese Webnovel company. You won’t find anything under that tag. But here are some “Isekai” novels I guess it’s isekai, China don’t really go deep into Isekai like accidentally killed, get power from god, become op etc.
Warlock in Magus World
-I am pretty sure the character himself is from earth and got transported. He has a Ai chip to help him. All I can say is this MC is cold-hearted and twisted. If you are looking for those goody two shoes might not want to read it. No harem. The novel is completed on Webnovel.
Gourmet of Another World
-it is a system novel. The MC got transported from Earth, there are hints of it throughout the book small hints but they are noticeable. Its about a chef that need to serve food and the money they give, increases his cultivation. If you are looking for a fighting novel, than this might not be for you. They have fighting, the world still revolves even when he cooks, he just gets pulled into problems by his system and things he do. Characters die, not many are forgiven. But no harem so don’t even think about it.
Tales of Herding Gods
-I wouldn’t call this a Isekai necessary but the MC is from another “world” it’s hard to explain without spoiling anything. But read the synopsis and try it out. It might be slightly slow in the beginning but it picks up. Harem not so much, but the point where I stopped only 2 girls fought for him. I think. More if you think differently than I do.
Carefree Path of Dreams
-it is another novel written by the same author of Warlock in Magus World. I think the Mc is from another world, but he left that behind really fast. Still in translating process with 1 chapter a day. So far it is pretty decent.
That’s all I can think off from the top of my head. On another unrelated noted. The book called Tales of the Reincarnated Lord sadly is discontinued because of some things the author put in but it is one of the best novels I read. It is not on Webnovel and is free. There is a huge amount of info dump within the beginning of the book but it all connects to the novel as a whole. It is so incrediblely detailed and the empire building is so well done. And yes it is isekai. And it is very realistic too. The point where the author was stopped seems like a pretty good end. I highly recommend you go and read it.
