Suchen nodded and went on walking towards the cave.

Since there is no sign of energy stone outside, it must be inside.

The cave is still very deep. It took about 400 meters to reach the end.

Only see the end of the stone wall, shining a piece of crystal light, as bright as stars.

Suchen took a deep breath, went near and looked at it carefully.

However, the hard stone wall is inlaid with dozens of white crystal stones the size of thumb, emitting glowing brilliance.

"Uncle Yang, is this the energy stone?" Suchen was a little excited.

From the appearance, the white spar is not very different from the energy stone, but he is not sure whether it is energy stone.

"It's energy stone, and it's of excellent quality. At least it's all energy stones above grade 1." Yang Lingtian said excitedly.

Hearing this, the other people's eyes were shining.

The appearance of energy stone means that it is probably a vein of energy stone.

The value of energy stone vein is unimaginable, and it is undoubtedly a treasure land.

"Do it."

Suchen licked her lips, took out the super drill and began to protrude.

As a large number of stones were broken, the dozens of energy stones quickly fell off.

Then, a large number of energy stones appeared on the stone wall, dense, at least a few hundred.

The biggest one is half an egg in size.

"Uncle Yang, is this energy stone grade 3?" Suchen asked, pointing to the biggest energy stone.

Yang Lingtian watched for a long time and said excitedly, "this... Seems to be a level 4 energy stone."

Level 4 energy stone!

The cave was filled with exclamations.

Suchen swallows and spits.

At first, he thought it would be good to get a level 3 energy stone, but he never thought it would be a level 4 energy stone.

The value of level 4 energy stone is far more than that of level 3 energy stone, which can be exchanged for more than a dozen Level 3 energy stones.

Su Chen couldn't hide her joy, her eyes narrowed into a seam.

Relieved, he went on digging the energy stone.

When the exposed energy stones outside were excavated, a large number of energy stones appeared inside again, as if there was a feeling that they could never be dug out.

Suchen enjoyed the feeling and became more and more energetic.

An hour later, thousands of energy stones were dug out.

Among them, there are many ordinary energy stones, there are also many grade 1 and grade 2 energy stones, and there are only three grade 3 energy stones.

What Suchen needs most now is level 3 energy stone, because he plans to upgrade [mech] to level 3.

Once promoted to level 3, you need level 3 energy stone or energy stone to drive.

Three level 3 energy stones are obviously missing.

However, he was not a bit discouraged.

Because through psychic exploration, he found that there are many energy stones in the stone wall.

Compared with the energy stone mined out, the real big head is still in it.

"Morning brother, you have a rest, let me dig for a while." Yang Hao proposed.

Suchen has been digging for an hour. It's time to have a rest.

Moreover, Suchen is their worthy boss.

How can the boss do it himself?

They can do the work for the younger brother.

"Well, you come." Suchen nodded.

Yang Hao used the "super drill" once, but he still had some experience in this aspect, so he put the "super drill" into Yang Hao's hands.
