Deliberate Suppression

At the Underground Base, Fein just stared at the passing clouds with a serene expression while waiting for Gregory. 

"This Underground Base really turned into a second home for me," Fein muttered.

Since he came to this world, he discovered his system in this place. He also awakened his degu energy. Now, he spent almost all of his time training here and practicing his new abilities. 

The Underground Base would always have a unique place in his heart, no matter what happens. This is why Fein wants to build an Underground Base in the future headquarters of his organization. 

The convenience and usefulness of Underground Base had become apparent to him after a long time of using one.

"What are you thinking?" 

Gregory's voice sounded behind him. Fein turned around to see his captain walking in his direction.
