Ye Qian is a fool abandoned by the family, intimidated by his classmates, and bullied by his dorm mates. At one time when he woke up, his memory joined an immortal cultivator from the immortal realm. Since then he has knowledge and memories from his previous life.
I'm gonna be honest, this was super mediocre. It has decent potential but I dropped it simply because every site had a poor translation and was missing pages so it made a story that was already really fast paced and had bad transitions impossible to follow what was happening. The story itself was not so bad you would drop it, but only good enough to follow when the probably 20 other rebirth cultivation stories your reading don't have new chapters. If you find a site not missing pages even with meh translations throw it in the comments and I'll read more of it and see how it pans out.
