I Am Cultivating Immortality in a Mysterious Place

I saw the world of Gaowu, but was what I saw real... Zhang Yuan is in the seventh level, but why does a golden elixir appear in his dantian... Every night, Zhang Yuan would hear women crying, but every time he woke up, no matter how he called his roommates, they seemed to have died in sleep, without any response... Every morning, the roommates would tell Zhang Yuan that they heard women crying every night. Everyone was woken up every time, but Zhang Yuan, no matter how they shouted, there was no response... "Zhang Yuan, can you please open the door? I am Lin Shuangshuang. I am so scared." Zhang Yuan turned his head strangely and looked at Lin Shuangshuang beside him... "Sister nurse, thank you for your help." Zhang Yuan lowered his head and instantly saw a corpse-like nurse staring directly at him... The first rule of mystery: ghosts will not appear when you are two people... When Zhang Yuan went to bed at night, his whole body glowed, as if he was... Practicing on his own?!
