In the old days, digging was really the way to mine by using a stone breaker, a rotary cutter, an excavator, and other tools for digging holes in the rock. It was easier these days, and the miners didn't have to suffer so much. They used a mechanical digger to remove the back-filled gravel while they were digging.
It was still tiring, but it was a lot easier than digging holes in the rock. It was also safer, as long as you looked at the terrain and dug through all the rubble, being careful not to get buried.
After only half a day, the hole was almost cleared, and a wide hole about two meters in diameter appeared in front of them.
After lunch, Li Du returned to the mine to work. After entering he was just about to start when suddenly, Brother Wolf pulled him back.
"What's the matter?" he asked in surprise.
Brother Wolf stared in front of him and said, "Snake."
