Chapter 152: Level 4 Energy Stone

Su Chen nodded and continued to walk towards the cave.
Since there is no trace of the energy stone outside, it must be inside.
This cave is still very deep and it took more than 400 meters to reach the end.
I saw a piece of crystal light shining on the stone wall at the end, as bright as a star.
Su Chen took a deep breath, walked closer, and looked carefully.
However, dozens of thumb-sized white spars were inlaid on the hard rock wall, exuding scorching brilliance.
"Uncle Yang, is this the energy stone?" Su Chen was a little excited.
The white spar is not very different from the energy stone in appearance, but he is not sure whether it is an energy stone or not.
"It is an energy stone, and its quality is very good, at least it is an energy stone above level 1." Yang Lingtian said excitedly.
After hearing it, the eyes of other people lit up.
The emergence of energy stone means that this place is likely to be an energy stone vein.
The value of energy stone veins is unimaginable, and here is undoubtedly a treasure place.
"Do it."
Su Chen licked his lips, took out the [Super Electric Drill] and started to bulge.
As a large number of stones were broken open, the dozens of energy stones quickly fell off.
Immediately afterwards, a large number of energy stones appeared on the stone wall, a few hundreds of which were densely packed.
The largest piece is half the size of an egg.
"Uncle Yang, is this energy stone level 3?" Su Chen asked, pointing to the largest energy stone.
Yang Lingtian looked at it for a long time, and said excitedly: "This... seems to be a level 4 energy stone."
Level 4 Energy Stone!
There was an exclamation in the cave.
Su Chen swallowed even more.
At first, he thought it would be good to get a level 3 energy stone, but he never thought it was a level 4 energy stone.
The value of Level 4 Energy Stone is far more than Level 3 Energy Stone, which can be exchanged for more than a dozen Level 3 Energy Stones.
Su Chen couldn't hide his joy, and his eyes narrowed.
After a sigh of relief, he continued to excavate the energy stone.
When the exposed energy stones were excavated, a large number of energy stones appeared inside again, as if there was a feeling that the excavation would never be finished, and it would be endless.
Su Chen enjoyed this feeling very much, and became more motivated to dig.
One hour later, thousands of energy stones were excavated.
Among them, ordinary energy stones are the majority, there are many energy stones of level 1 and 2, and energy stones of level 3 are the least, only three.
What Su Chen needs most now is the Level 3 Energy Stone, because he plans to upgrade his [Mechanical Soldier] to Level 3.
Once you are promoted to level 3, you need a level 3 energy stone or energy stone to drive.
The three level 3 energy stones are obviously missing.
However, he was not discouraged in the slightest.
Because through the spiritual exploration, he found that there are still many energy stones in the rock wall.
Compared with the mined energy stone, the real big head is still inside.
"Brother Chen, take a break and let me dig for a while." Yang Hao suggested.
Su Chen had been digging for an hour, and it was time to take a break.
Furthermore, Su Chen is their well-deserved boss.
How can you let the boss do the rough work of digging energy stones?
They can do it for the little ones.
"Well, come on." Su Chen nodded.
Yang Hao has used the [Super Electric Drill] once, and he still has some experience in digging. He also put the [Super Electric Drill] in Yang Hao's hands.
