Chu Xi, a once-in-a-hundred-year Taoist genius, was nailed into a bronze coffin on his twentieth birthday in order to survive.
When the coffin board was split open by lightning for the 999th time, the girl opened her eyes in another world and became Chu Xi, a 15-year-old female high school student.
In this world, there are evening self-study classrooms where math papers are flying all over the sky, and ghosts and monsters are dancing in the square outside the window. It is actually an era of spiritual revival.
Chu Xi found her glimmer of hope: the peach wood sword that slayed demons in the middle of the night was disguised as a 2B pencil during the day; the cinnabar charm that sealed evil spirits had trigonometric functions written all over the back.
What can I do? I can only save the world while going to school.
Intention: Self-reliance and self-reliance
