After his training, Fein went to one of the mountain in the mountain range near his laboratory.
Fein stood at the base of the mountain, his eyes scanning the surroundings. His heart raced with anticipation as he made his way towards a nearby tree. He pressed a hidden button on the trunk, and the ground beneath his feet shook. A loud rumbling echoed through the air, and the mountain ahead of him split in two with a deafening crack.
Fein's lips curved up into a small smile as he stepped forward, peering into the newly revealed opening. The darkness within was thick and impenetrable, but he knew what lay ahead - his newly created headquarters. He took a deep breath, steeling himself for what was to come.
