Li Yinxiu accidentally traveled to a high school student and found that this world was a little different from the previous one. Through the simulator, we learn that spiritual energy will be revived in one year, and people's lives will undergo tremendous changes.

It is normal to make some mistakes in the first attempt. Please point out the inappropriateness, thank you)
