Xu Liyang, a descendant of a well-known scholar's family, with an above-average IQ; the last generation, a Taoist priest who created the world because of it, had the five senses of the world, and died at the end of his life span. I firmly believe that "there is warmth beyond destiny." A causal entanglement that goes beyond any formula or spell makes life seem more interesting.
The last generation calculates the trajectory of destiny with its fingertips, as calm as a precise machine. She is afraid of cause and effect, but she chooses to intervene in cause and effect every time. Because there is Xu Liyang and more partners around him.
She deduced the truth and punished the devil who bullied others, while he silently helped her. She uses magic to help kind-hearted people save the orphanage and let more people see hope. Watching her silently deduce and complete the omissions, she never stopped even when she had a headache. She helps the victims get justice, so that the theory of victim guilt is no longer rampant... She always acts alone, and she does not want others to be involved in the cause and effect and suffer backlash. Xu Liyang didn't know when he started to feel sorry for this silly girl.
Many people say who cares about your meager strength? How many people can you help? The last generation always smiles calmly, that's enough for me.
While using magic to help others again and again, something went wrong and a good friend lost his true love. Questioning herself gradually engulfed her. But he came and intervened in this cause and effect without hesitation.
When the gears of fate rolled over again, the last generation finally understood: there is only one thing in the world that cannot be deduced - no matter what, she will fall in love with this silly boy who guards her.
