The smallest was at least three meters long, while the largest was nearly ten. With the jumble of undulating rock pillars stacked on their backs, they looked like small mountains. No wonder Yin Yi couldn't pull them all out of the ground in one go.
Dean Wu stared at the struggling turtles with fascination, as if he had discovered a priceless treasure. "Interesting," he said slowly. "We'll take a few back to study. They might just be a great help to us."
"Besides these black turtles, the three Rock-Breaking Ants have found traces of coal at a depth of nearly 600 meters, 500 meters away from our position. This indicates that this region has at least five million cubic meters of coal reserves."
Five million cubic meters was just the amount discovered in a small, explored section. Han Ning had no way of knowing the total reserves for now.
But at the very least, this much coal was enough to supply an academy of several hundred people for some time.
