Whereas, the so-called treasure hunting monster Devon was fast asleep on the bed.
As soon as Devon got to his room, he fell straight to the bed. He was exhausted, he had barely managed to make it back to the auction because of the aftereffect of using the cosmic energy.
Cosmic energy revolves around the body structure. Which makes it hard for humans with weak physiques to use the energy.
And when they do, they are left with a serious aftereffect that was capable of leaving some of them bedridden for the rest of their lives.
Unlike celestial energy, cosmic energy was hard to utilize for any human. It belongs mainly and solely to the Demons due to their body structure and the world they reside in.
This was also why any human who forcefully gains cosmic energy would turn to an inferior grade Demon. It was mostly due to their body not being able to handle that violent energy.
