Chapter 162: Chapter 157. The Specter’s Core

"Still as nasty as ever," Zein commented as he stared at the pulsing cores. 

Even through the thick protective glass, the sinister dark smoke swirling inside the three tubes gave out a pressuring aura, which was the source of the heavy and gloomy vibe in the observer room. It consistently caused the researchers stress and fatigue, just like how it would be if civilians were to be exposed to miasma. 

This danger was the reason why most of the researchers involved with the specter cores were espers. Even with that precaution, they still experienced fatigued and heaviness every few weeks, as if they were being corroded. So aside from watching the cores, Zein was also there to cleanse them.

Which was why, his visit was always welcomed enthusiastically.

"Sir Zein," the chief researcher here whom Zein already met last week, Fei, greeted him with a smile. "I've never seen you here on Saturday."
