Capítulo 157: Mysterious Material - Extreme Training

The moment Nikolai reached the basement where Alexei was waiting, he felt quite curious. Not only did the walls become thicker with each floor below ground, but there were thick metal supports. Yet the metal wasn't one that Nikolai recognised... 'Is it something from the Nexus?' 

He noticed the rooms became smaller but more extravagant and of higher quality with each floor down he went. Once at the door to the private training room, he noticed not a sound had come from inside. 

"I can't even hear any ambient sound..." This was with his enhanced senses; earlier, he could still hear people from the top floor. Yet once entering this basement floor, all sound vanished.

*Knock*

"Ouch..."

Nikolai knocked on the door, made of the strange metal from the support beams and pillars. However, the moment he did, a sharp pain shot through his wrist and knuckles. The metal was extremely durable and strong!

"Is he not here?"
