I will just describe it in one word and that is 𝙥𝙚𝙖𝙠. Yeah that's it. According, to me Fang Yuan is the best protagonist in fiction and it is also my favourite novel. Definitely better than Shadow Slave, Omniscient Reader's Viewpoint, Re:zero etc. The only novel which can match it is Lord of the mysteries. And still Fang Yuan is the better lead. 

d*mn the Mainlead of this novel is so cringe and pathetic that is sucks. He is the total opposite of Fang Yuan and even more pathetic than early regressions Subaru(no hate to subaru but in the early return to death, he was somewhat pathetic). The novel mainly focus on martial arts instead of cultivation. The chapters are so d*mn long and until I think chaptere 60, he is not even a cultivator but instead trying to reach the peak of martial arts so that he can become powerful enough to start cultivating. Idk how is he even a cultivator. Korean author just can't write a good mainlead(except Kim Dokja) and a ruthless mc. Idk why is a Korean author even trying to write a cultivation novel when he can't make mc cold and smart(mc is that one dumb person you find in McDonald's). Overall rating 2.5/10 from me and that only because it is a cultivation novel and therefore has some potential. 

Literally the best horror genre book to exist in whole fiction. Read it you won't regret it I assure you. Read only the first 4 or 5 chaptets and you will get what I am trying to say. All the scenarios, ghosts and missions are very creatively and uniquely created. 10/10 horror and thriller genre
