Fixten

[Simulation shall commence.]

On this fateful day, the world was stunned by the appearance of ancient animals that were supposed to have gone extinct for millions of years. Huge sinkholes appeared in every corner of the world, becoming a tunnel for the ancient animals to emerge to the surface. 

Humans have found an answer to one of the biggest mysteries in human history. Hollow Earth is real. Here, humans will wrest their lives to explore this new world that has existed for thousands, if not millions, of years underneath them.

Before the start of his exploration, Clovis came across a place called ‘Another World Mall.’ 
Dwarven Sword, Magical Elven Clothes, or Giant Race Toy? Everything can be found in this ‘Another World Mall.’ 

As an aspiring Subterranean Explorer, how would he utilize this ‘Another World Mall’ to become the greatest explorer of all time and find the truth about the simulation?

Another World Mall

Hana was looking through the city from the restaurant.

"Hello, Miss Hana." A middle-aged man approached her. He had a rather gentle face, but she could sense that underneath that suit were muscular arms. "I apologize for making you wait."

"It's fine. I just love to come thirty minutes early." Hana smiled. "You're not late either."

"Ahaha." The middle-aged man's smile became awkward. Even though he wasn't late, he still made Hana wait for fifteen minutes. "Please allow me to introduce myself formally. I am Damian Heshton. I'm currently the director of Releson Medical Center."

The middle-aged man couldn't help but feel a bit pressured both by Hana and her bodyguards.

Hana actually came with two bodyguards, considering the Heshton family could harm her if she brought any less. Each bodyguard was actually a Tier 8. Both of them looked like they had been nurtured by her grandfather.
