A disturbing aura flowed from the body of the Emperor of destruction who had taken Professor Mia seriously.
Professor Mia slowly retreated a few meters back. The aura that The Emperor of destruction released possessed danger to even someone like her.
Professor Mia's face distorted sadly as she looked at her student who had lost his sanity.
( A way to help Zero… )
She thought but she knew it would be impossible.
She bit her lip until it bled. Just looking at the Dark energy that was being released by Zero, she knows that it was more than anything she had ever faced. Even some of the Elite demons she killed didn't possess such Dark energy.
( Don't tell me… Zero signed a contract with Demon King. )
Only those Demons whose rank was Duke and above could produce such intimidating Dark energy. For a human to get it to similar quality, the contractors need to be a prince or Demon King rank.
The Emperor of destruction used his skill right after he finished releasing his Dark Energy.
