A hole the size of a fist was exposed.

Tang Zheng worked harder and continued to expand the hole.

Until the black hole that can hold a person to crawl into is revealed.

Tang Zheng took the torch and probed inside the cave.

The blazing fire illuminated the darkness.

This is a closed cave!

After millions of years of movement of the rock mass, some terrain that was originally a gully was covered, but it was not completely filled, so this kind of hole in a hole was formed.

Because of its hollow interior, the infiltration of rainwater will cause an oxidation reaction with the bedrock.

In other words, it is easier to spawn some metal ores.

Tang Zheng was not in a hurry, but first threw a small stone inward.

Don't look at the position where he is standing now, but it's not necessarily a hole in a hole.

If there is a [-]-meter deep pit, you will die violently if you enter it.

Fortunately, the stone gave the feedback sound of landing almost instantly.

Only then did Tang Zheng settle down.

"Wealth and wealth are in danger!" After giving himself a boost, he cautiously got in.

Wherever the torch reached, the nearby walls were all printed red.

But it's all granite, nothing different.

"what?"

Suddenly, Tang Zheng let out a surprised voice.

"Is this..."

His breathing became a little short, and he took a closer look at the torch in his hand.

Under the light of the candle, Tang Zheng could see clearly what was in front of him, and said it was a mine. Just looking at it, it was not as hard as minerals.

But let's say it's mud, and it's more peculiar than the shape of mud.

If you have to use an analogy, it is more like the reinforced concrete blocks on the construction site after the illegal buildings were demolished.

The overall color is dark gray, like dried charcoal.

"Coal mine?" Tang Zheng thought to himself, put a little on his hand, and opened the picture book for identification.

【Clay (Ordinary Grade)】

[Attribute: One of the main components that make up the geology]

[Description: Without it, any life will be gone]

【Ding!Congratulations on completing the quest 'Mining Ore'!Neolithic Progress (3/4)! 】

Tang Zheng was immediately overjoyed.

I wanted to do the mining task.

Unexpectedly, the clay was dug out directly.

Moreover, clay is also one of the minerals, which he did not expect.

This time the pottery has also fallen, killing two birds with one stone!

It is a little regrettable that mining still failed to unlock the world's first time.

It seems that there are always people who are not doing their jobs, and go straight to mining when they are still relatively wealthy.

However, the pottery Tang Zheng is confident to win the world's first.

Now the human beings over 95 are running around to make a living, and the remaining 5 people who do not worry about food and drink, or elites, may have free time to think about other things.

But they need at least one kiln to make pottery, even if it is an earthen pit kiln, it takes a long time to build.

And you only need to throw it into the synthesis table to synthesize.

Without a second thought, all the clay on one wall was directly buckled.

He turned around with the torches again.

Tang Zheng also identified some iron ore by accident, but not much.

And with his current tools, it is still impossible to mine.

He turned back to the entrance of the cave and made a rattan basket, and when he came back, he threw all the clay into the basket.

I thought this basket of clay would be very heavy, but Tang Zheng felt the weight on his back.

Unexpectedly light.

These 11 points of strength are really not for nothing, and the whole body is full of strength.

After adding a few more pieces of granite to the basket, Tang Zheng folded back to the wooden house and started to burn pottery!
