After sending off the program crew, Lin Yu'an was alone again.
He walked back to the workshop, where the half-finished Ice Drill was quietly awaiting its final transformation.
He placed the steel rod used as the drill shaft into the fireplace, utilizing the burning firewood to slowly heat its tip to a dark red, hot enough to burn through wood.
Then, he selected a piece of birch from the pile prepared for the ice fishing shelter, about half a meter in length and thicker than his wrist.
Using a hand axe and a hand saw, he roughly carved out a T-shaped outline from the wood, then patiently sculpted a smooth handle prototype with a sharp Hunting Knife, one that he could grip with both hands.
Next, he used a bow drill to bore a guide hole in the center of the T-shaped handle, slightly smaller than the steel rod's diameter.
He aimed the heated tip of the steel rod at the guide hole on the handle, then forcefully and steadily pressed it down with both hands!
"Sizzle——!"
