Energy

Pingan High School.

Li Ke looked around the school before he took a deep breath and lowered his head to resume reading his book since they will have an exam in their next subject. But, he can't concentrate right now after he received Su Yu's message, which is about the energy level of their school.

Su Yu: not only the yin energy in your school is strange, but also the yang energy. No wonder the atmosphere of your school is very strange. Because the yang energy is also barely present despite it is a school, which should be abundant in yang energy coming from both the students and the teachers. It is already fortunate that with the insufficient yang energy of your school, it was not overwhelmed by the yin energy despite the fact that your school was built over a mass grave that is also abundant in yin energy.
