Just after a group of people who had been lost for a long time fled as if escaping for their lives.
Swoosh! Swoosh! Swoosh!
...
Silhouettes, swift as meteors streaking across the night sky, swept in from afar, and in an instant arrived at the outskirts of the fog-laden land, where they each halted.
As they stopped, their shapes and appearances gradually became visible.
There were four young men and two young women.
"It's inside,"
said one of the young men, sturdy and with bushy eyebrows and large eyes, as he looked at the fog-laden land before him, his eyes gleaming.
"This place... seems unusual. It doesn't feel like a 'Human Grade Vault'."
Another handsome and refined young man added.
His words were quickly met with agreement from the other two young men:
"Indeed, it's different from the Human Grade Vaults we encountered before."
