However, the scene in the Immortal Sect suddenly changed - the fellow disciples who had laughed at Yan Yan yesterday turned into ferocious insect-shaped monsters in his eyes overnight!

In order to survive and to tear apart this suffocating disguise, he is determined to explore the horrifying truth behind this strange world.
