"The rules are very simple. Can you see the halo of light from those experts on the battle platforms?" The immortal controlling the avian beast pointed to the Cloudheaven Arena. The others nodded, staring at the battle halo radiating around those experts fighting there. There were some weak ones and some strong ones, but the stronger an individual’s combat prowess was, the brighter their battle halos would be.
