The concave-convex world is the coldest in Greer. Greer, the role in the IP concave-convex world of Qichuang Society and its derivative works. One of the contestants in the bump contest. The mysterious swordsman who is calm and rational seems to be indifferent to everything. He has a clear purpose in doing things, and he can do whatever it takes to achieve it.

Beneath the cold exterior is a man's throbbing heart. I will deliberately hide my enthusiasm and show my cold side to others.
