It was just another typical day for Xiaohu Zhang, navigating the challenges of high school life. Engrossed in classes, he diligently worked on his lessons and focused on finishing his homework during class hours, just like any normal school day.

Little did he know, a bizarre twist awaited him. As he settled into his apartment, Xiaohu unexpectedly found himself opening his eyes in a new reality—a prehistoric Chinese setting. To make matters more bewildering, he discovered he now inhabited the body of Liyu Chen, a girl from this ancient era.

Meanwhile, in the modern world, Liyu Chen found herself in control of Xiaohu's body. Bewildered by the unfamiliar surroundings, she stumbled upon a television and, deeming it strange, destroyed it. In shock, she hid, realizing the low spirit energy in the modern world hindered a swift return to her original form.

Back in the ancient setting, Xiaohu Zhang, now in Liyu Chen's body, examined himself in the mirror, utterly shocked by the transformation. Their worlds collided when a passerby, Jianyu Wang, made derogatory remarks about Liyu Chen's caretakers. Enraged, Xiaohu challenged Jianyu Wang, leading to a brutal confrontation. Demanding an apology, Xiaohu threatened further violence unless the caretakers were brought back.

In the midst of this chaos, bystanders were shocked by Liyu Chen's unexpected display of strength. Unaware of the body-swapping, they marveled at her prowess, while Xiaohu, trapped in her body, grappled with the strange turn of events. The stage was set for an unfolding saga of unexpected transformations and the mysteries surrounding Xiaohu and Liyu Chen's entwined destinies.
