Keep reading. It gets better. I think within the first 10 chapters or so?
Yeah I had the exactly the same thoughts as you did, but out of boredom read it for a while and got so hooked.
So either drop it and save yourself the hook or the trouble of reading a bad series
Or carry on and see what...
But read it through, you will get good inspiration for your own works. It's really well done fantasy and also isekai protagonist. "io" prolly has it fully, the comick one. But you know, you can also read it legally. I did, it was that good.
