Tunnel

Tunnel is one of the combat personnel of the Munitions Factory sent to kill Lin Sanjiu in Heaven Underworld. He also seems to be the brain of his team.

A pair of spectacles sit on top of his high cheekbones. His cheeks are sunken in that it seems like there are holes on his face.

Personality
Tunnel seems intelligent and sharp, as he was able to catch onto Lin Sanjiu's tricks quickly while in pursuit of her.
