Back in the mine, Gu Beifeng stayed at the bottom to rest temporarily, while Yang Xiao and others went ahead to mine in the tunnels.
Everyone had been mining for a while when they realized that mining was truly a labor-intensive job.
Besides Yang Xiao, the rest were all King Level Evolvers, but each person could not continue mining for more than 15 minutes without feeling tired.
Another discomfort was the need to widen the tunnels to the previous width of five or six meters and a height of three or four meters; the excavated rubble had to be transported to a place two to three hundred meters away, then lifted by an elevator to a hundred meters outside the mine, where it was then carried by people outside to a place a hundred meters away and piled up.
Everyone took turns on the job, and after several hours, they had only advanced about one meter.
