Pick up an Identity and Walk Sideways

This is the first time for my family to write something like this. Please comment and I will correct it next time. When she woke up, she forgot who she was. A lonely soul with no roots and no evidence is floating in front of the spiritual testing platform of the Immortal Cultivation Sect, watching all living beings test their spiritual roots and enter the Immortal Sect. No one could see her—until when the disciples were leading the new disciples away, they "brought" her in as well. Entering the sect by mistake, entering the secret realm by mistake, and lying on a ten thousand-year ice bed that can nourish the soul. When she woke up two or three months later, she found the body of an outer disciple at the door who had been dead for half a month and had not been noticed. So she had a new identity: Shen Qi, a low-ranking pseudo-spiritual person who was at the bottom of the handyman hall and was bullied by everyone. But she doesn't care. After all—— "I'm not really Shen Qi." While she was fishing in troubled waters in the sect as a useless disciple, she was secretly searching for her true origin. But as the noise she made became bigger and bigger, the inner genius senior brother who always treated her coldly and looked down upon her seemed to be getting more and more wrong. "Who are you anyway?" "Do you believe me when I say I borrowed a corpse to bring back the soul?" "... You say it again?" She grinned: "Brother, your ears are hard to use. I said - borrow, corpse, return, soul." Crazy criticism of the chatty heroine × cold-faced, sultry senior brother
