My Subject God

In the school library, Jiang Yue, a low-profile girl, opened an ancient sheepskin book that had been dusty for a long time. Four male gods of physical, chemical and physicochemical properties and Yangxuan were released. They appeared next to Jiang Yue, and approached with different routines for different purposes.
Why did the male gods from the seal and return to each other gradually approach Jiang Yue? What kind of fantasy journey did their appearance bring to Jiang Yue's campus time? In addition to unblocking the subject male gods, what subtle feelings did Jiang Yue's unknown cause?
These answers have no common routines, only a fantasy journey led by a male god.
