I read 80 chapters and I can say this novel has a lot room for improvement. For beginning... Let's start with MC, he spent 400 years in hell... I guess it killed most of his brain cells. Zero research about 'hunter' actions before becoming one. If not plot armor, his stupidity would kill his family. Writing quality needs some editing. Some typpos here and there. Some sentences are quiete broken. WQ - 3 stars. You should consider editing your story before putting it before pay wall. None likes paying for being proof reader...SU - 4 stars. Story dev. - 3 stars. It's okay... Ruthless protagonist trying to improve his family situation and acts like wuxia protagonist killing random guy son. Blah blah blah. It could be avoided with some brains.Character design - 2 stars. It's probably weakest side of this story. Most of characters are cliché or bland. World background - 4 stars. Currently it feels like default Korean novel.This rating might improve if you make things better later in story. This review is based on free chapters. Maybe, you started to put more effort after getting contracted. I will visit later... No money for spirit stones and run out of passes. I hope this story improves. Good luck.
