At the small book stand in front of the school, I bought this thread-bound ancient medical book for five yuan. Since then, I have become a little fairy doctor who heals people and ghosts. As long as there is enough medicinal energy, any difficult and miscellaneous disease can be cured. Any opponent can be crushed into scum. Teacher Yujie, rich lolita, innocent landlord, sexy policewoman, and so on. Ye Youran really wants to say, I'm just a student, please let me go !
