*Tick!! Tick!!! Tick!!!
The echoes of metal hitting stone traveled through a tunnel.
And there wasn't just one of such sounds being made in that certain tunnel.
But it wasn't before long that a different sound appeared in the tunnel.
*Ting~ting~ ting~~
"Haah~haah~haah...so hot..." A man with haggard breathing said as he felt his body burning from the inside.
"Hey! What are you doing!? Pick up your pickaxe before they come!" The voice of the girl that was not far from him spoke with a harsh voice.
The man briefly looked at her before nodding.
"I-I know..." The man said as he stared down at the pickaxe that he dropped.
His gaze was dizzy and he was thoroughly exhausted.
But he knew that the girl was right.
He bent his waist, reaching out with his two arms to pick up his pickaxe to continue, seemingly aimlessly hitting the rocks that they assigned him to hit.
