My Heavenly Book Only Has Eight Words

When Nan Fan woke up, he found that he had become a handyman disciple at the bottom of the cultivation sect. The original owner "accidentally" fell off a cliff three months ago, and the cause of his death was full of doubts - the sect elder Xuan Ming's eyes had never taken away from him from the beginning. There is no spiritual root, no backing, only a broken ancient bronze scroll of unknown origin deep in the sea of ​​consciousness, engraved with eight ancient characters that no one can decipher: [broken] [broken] [empty] [empty] [square] [ke] [return] [place]. What's worse is that his body hides a taboo that should not exist in this world. Using blood as a guide and body as a furnace, the closer to death he becomes, the stronger he becomes. Every healing pushes him away from the boundary of "humanity". In this world that eats people without spitting out their bones, he just wants to survive and find out why he is here. But Master Xuanming will not give him this time, nor will the secret sealed in the forbidden area of ​​​​the back mountain. Shatter the void before you can return home - are these eight words the path of cultivation, or is it the prison where he is trapped here?
