Can anyone tell me what this arc called in the novel?

73rd demon realm. This is around ch 190+

Do you think it's worth just skipping to it if I want to read the web novel or should I start from the beginning?

I recently started the novel from the begging and it's honestly really nice to reread it all again. I've realized I've forgotten quite a lot of things, bcs the comics has been coming out for so long now.

I think itd be better to read from the beginning. Some details in the manhwa are ommited but if you didnt really want to read from beginning but from ch 190 then i dont think youd be missing much. I personally loved the novel so id say from beginning but honestly just whatever you prefer
