An immortal… indeed, an immortal would have a strong yang energy with his powers he cultivated by absorbing spiritual energy from the environment. But, as far as they know, it is only Kong Weijun, Yue Qinghan, and Duan Yuan who are immortals that are in here in this world. Su Yu is just half an immortal lord, since he is half a demon lord at the same time. Meanwhile, Nie Fan is a full demon, and also can be considered a demon lord in this world.
So, who is this other immortal? Who is he that could suppress the yin energy in Li Ke's school that could make Li Ke's school a potential yin land? No wonder that the atmosphere in Li Ke's school is strange, since there is supposed to be a great yin energy there to transform Li Ke's school to a yin land, but then with this great immortal present, the yin energy was suppressed.
