She wanted to teach peacefully, but accidentally triggered the sign-in system in a dilapidated temple and obtained the skills of a mortal to cultivate immortality. The system requires her to sign in every month to improve her cultivation and unlock the answers to the imperial examination questions. While teaching children, she practiced secretly, and at the same time participated in the imperial examination, crushing her from a child student to the number one scholar. When the rich and powerful coveted her imperial examination results, she shocked everyone with her ability to cultivate immortality.
