England, South Wales, Swansea Coal Mine.
In the mine shaft over 170 meters deep underground, old David, on all fours, desperately banged on the air-door in front of the passage while shouting, "Jamie! Open the door quickly, Jamie!"
The air-door was used in the mine to prevent excessive accumulation of methane and carbon dioxide. A child would wait behind the door at all times to open and close it for the coal pushers.
However, there was no response from the other side of the door.
In the pitch-black tunnel, old David turned to encourage his companions behind him, "Don't worry, the kid is just asleep."
He had no idea that they were already in a desperate situation.
Jamie's family hadn't eaten sugar cakes or had tea with sugar for a week, and due to a lack of sufficient sugar intake, he simply couldn't withstand the heavy work for 17 hours every day.
Half an hour ago, he had already fainted.
