"The ancient Babylonian king promulgated the Code of Hammurabi, which was engraved in black basalt, which has been more than 3,700 years ago..."

After taking a shower, Tang Zheng hummed a little tune and took off the "shower" hanging on the branches and wringed it out.

The originally white T-shirt has turned brown and yellow at this time, with countless fine sand and mud inside.

Help Tang Zheng filter out a lot of dirty things.

It was rinsed in the puddle and it was clean, but not completely clean.

After taking a bath with a bath that is not very good, but when he thought that many people could not even drink water at this time, he could already achieve freedom of bathing, Tang Zheng stopped thinking about the problem of poor water quality.

Be content and be happy.

After putting on my pants, the sky was already dusk, and the last orange light was shining in the sky.

Go home!

"Pu!"

Suddenly, Tang Zheng kicked a small stone at the foot.

Looking down, I found that the stones were dark all over, but they reflected a faint white light.

The lines on it are crooked white lines like peeled oranges.

"Huh? Basalt?" Tang Zheng couldn't help but be surprised. The lyrics he hummed just now were still carrying basalt.

When it comes to Cao Cao, Cao Cao will arrive.

Judging from the introduction of the Encyclopedia of Everything, basalt is actually a kind of volcanic stone.

It is a legacy of the volcanic eruption.

Of course, to be more precise, it is the main sphere of rock that makes up the planet.

The huge energy generated by the volcanic eruption sprayed them onto the surface from the depths of the ground.

The texture of this rock is very hard. The high-temperature magma of thousands of degrees Celsius in the volcano cannot melt them. Instead, it is more like coating them with a layer of "obsidian armor". After being sprayed out of the surface and oxidized reaction with the air, it will become harder.

It is as hard as iron. In addition to talking about a certain part of a man, it is often used to describe the black stone.

"With the black trunk stone, we can process tool resources with harder materials." Tang Zheng suddenly became interested.

At this stage, the stone axes he synthesized are very wear-off. He almost needs to change to another axe when cutting a tree.

And it's not fast.

Time-consuming and labor-consuming.

If you have a stone axe made of basalt material, when wood is needed in the future, the efficiency of cutting trees will be greatly improved.

Moreover, the stone knife made will be sharper.

The benefits are numerous.

However, the black stone is too small, with an area of ​​just a small piece of palm, and it cannot be considered a piece of stone.

However, the fact that the black trunk stones appear here means that there should be some around.

Tang Zheng took out his cell phone and lit it up, and continued to search around.

Soon, he saw a large black treasure stone lying quietly on the ground not far away.

This black stone is more than one meter long, but not very wide, and looks more like a Western hot dog bag.

Nothing matters. As long as it is thrown into the synthesis table, it will automatically be processed into stone of the corresponding size.

"I'm a little lucky." Tang Zheng said intimately, squatting down his horse's stance, holding his hands directly on the two sections of basalt.

Use force!

My teeth were clenched and my gums were exposed.

The density of this stone is unexpectedly large, and it is so difficult with the blessing of 6.2 power.

It took a lot of effort to throw it into the synthetic Taichung.

Enter 'Stone'

Soon, the synthesis platform started to operate.

However, the production time displayed on it made Tang Zheng stunned.

[Remaining time: 5:59:56]

Such a large piece of basalt can make six small parts of stone, but one part of stone can be synthesized in an hour?

It seems that the material is definitely not ordinary, but a further quality level.

Tang Zheng was vaguely looking forward to it.

I don’t know how efficient the axe made from this kind of stone will be.

...

When I was still studying, Tang Zheng was puzzled by why the ancients locked down the city and banned pedestrians from night activities so early.

Because this special cat... has no entertainment facilities at all!

After taking a shower, I set up a bonfire outside the house to finish my last handful of instant noodles, and then took a big sip of water.

Liely lying on the weed-paved wooden board, Tang Zheng stared at the ceiling in the dark in a daze.

Have you lived a very good life...

Everyone is still struggling to fill their stomachs.

I actually started to feel spiritual comfort.

Expansion, too swell.

Tang Zheng had no choice but to go to bed early after having no time for entertainment programs.

First of all, the progress of the Neolithic Age is that the house has been built.

The last bag of instant noodles is consumed, and the food source should be considered tomorrow.

And how to obtain raw materials for pottery.

sleep!

In the middle of the night.

Tang Zheng was awakened by a chirping sound.

Take out your phone and take a look.

Tang Zheng suddenly had goose bumps all over her body.

mouse!

A room full of mice!

Under the light of the mobile phone light, the eyes were filled with ferocious green light.

Let's say it is a mouse, it's much larger than the common house rat, and it's the size of two palms.

Moreover, a pair of wind-catching ears are even bigger, almost the size of their heads.

How did these mice come in?

Tang Zheng looked at the gap between the surrounding walls that could be inserted into her fingers.

"I see."

The rats have very soft bodies and can come and go easily with very small gaps.

Tang Zheng alertly took out the short spear placed beside him.

He stood up and shouted loudly.

According to the habits of civilized society, these mice are usually scared by stomping their feet.

But it's different at this time.

Not only did they not run away, they squeaked more rampantly, making the surrounding wooden walls clatter.

Tang Zheng quickly opened the picture book and checked it.

【Wood-eating rat (normal creature)】

【Features: Live from wood, like to live in groups, and like to eat dry wood.】

【Note: No special lethality, but if you have a hobby of building a house in the wild, they will cause you a headache.】

Tang Zheng: “…

Who has the hobby of building a house in the wild?

Not forced out yet!

Everyone is forced to do it!

Fortunately, this is not very threatening to oneself.
