Su Chen nodded and continued walking into the cave.
Since there were no signs of the energy stones outside, they must be inside.
The cave was very deep. They only reached the end after walking for about 400 meters.
There was a sparkling light on the stone wall at the end of the cave. It was as bright as the stars.
Su Chen took a deep breath and walked closer to examine the wall.
There were dozens of thumb-sized white crystals embedded on the hard stone wall. They were glowing brightly.
"Uncle Yang, are these energy stones?" Su Chen was a little excited.
The white crystals did not look very different from energy stones. However, he was not sure if they were energy stones.
"They are energy stones, and they are of high quality. They are at least Level 1 and above," Yang Lingtian said excitedly.
Everyone's eyes lit up when they heard that.
The appearance of energy stones meant that there might be an energy stone mine here.
The value of an energy stone mine was unimaginable. There was no doubt that this place was a treasure trove.
"Let's do it."
Su Chen licked his lips and took out the Super Electric Drill and started drilling.
As a large number of stones were broken, the dozens of energy stones quickly fell to the ground.
Then, a large number of energy stones appeared on the stone wall. There were at least a few hundred of them.
The largest one was half the size of an egg.
"Uncle Yang, is this energy stone Level 3?" Su Chen pointed at the largest energy stone and asked.
Yang Lingtian looked at it for a while and said excitedly, "This … looks like a Level 4 energy stone."
A Level 4 energy stone!
Everyone in the cave exclaimed in surprise.
Su Chen swallowed his saliva.
At first, he thought that he would be lucky to get a Level 3 energy stone. He did not expect to get a Level 4 energy stone.
The value of a Level 4 energy stone was much higher than a Level 3 energy stone. It was enough to exchange for more than ten Level 3 energy stones.
Su Chen could not hide his joy. His eyes narrowed into slits.
After catching his breath, he continued to dig for energy ores.
When the exposed energy ores were dug out, a large number of energy ores appeared inside. It was as if there was an endless supply of energy ores.
Su Chen enjoyed this feeling very much, and the more he dug, the more motivated he became.
An hour later, more than a thousand energy stones had been excavated.
Among them, most were Common Energy Ores. There were also quite a number of Level 1 and 2 Energy Ores. As for Level 3 Energy Ores, there were only three of them.
What Su Chen needed the most now was a Level 3 Energy Stone because he planned to upgrade his [Mechanical Soldier] to Level 3.
Meanwhile, once it reached Level 3, it would require a Level 3 Energy Stone or Energy Stone to power it.
Three Level 3 Energy Stones were obviously too few.
However, he was not discouraged in the slightest.
Through his spiritual power, he discovered that there were still many energy ores inside the stone wall.
Compared to the extracted energy ores, the real bulk of the ores was still inside.
"Chen Ge, take a break. Let me dig for a while," Yang Hao suggested.
Su Chen had been digging for an hour, and it was time for him to take a break.
Moreover, Su Chen was fully deserving of being their boss.
How could they let their boss do such a rough job as digging for energy ores?
They could do it as his underlings.
"Alright, you do it." Su Chen nodded.
Yang Hao had used the [Super Electric Drill] once, so he had some experience in digging. He then placed the [Super Electric Drill] in Yang Hao's hands.
