It took Anwen five minutes to build the nest of the disc.

"How about you take a look?"

An Wen pointed to the extremely ugly wooden cage next to him and said to the disc.

Disc looked at the ugly wooden cage, angrily stretched out his paws, and slapped the wooden cage apart.

Then, it looked at An Wen with angry little eyes.

"Ahem...... Don't be angry, I don't know what kind of nest you want.

Think about it, after your previous nest is enlarged, is it just like the wooden cage just now?

I thought you liked this style of nest, but you didn't, can I blame it? ”

An Wen is serious nonsense.

After listening to the disc, there was confusion in his eyes.

Although its intelligence has improved significantly after upgrading, it is still far from that of humans.

Therefore, as soon as An Wen said this, the disc was a little confused.

"Otherwise, you should think about what kind of nest you want, and tell me when you think about it, and I'll make it for you, how about it?" An Wen said while the iron was hot.

The disc looked at An Wen, turned his head and climbed out.

In its small capacity, it began to think about what kind of nest it wanted.

Flickering the disc away, An Wen began to work.

"The wooden ox and horse are used to install the pickaxe, which does not require too many fine components, just to ensure that the pickaxe can be excavated non-stop.

In this case, the pedal can be removed, the gear can be directly connected to the motor, the head can also be removed, and the pickaxe can be installed in that position, and then keep running forward, so that the pickaxe can keep digging. ”

Anwen quickly designed a simplified version of the wooden ox and horse, and then began to assemble it.

In a wood processing plant, many parts are readily available.

It only took more than twenty minutes for An Wen to assemble this wooden ox flowing horse that didn't even have a head.

"It looks a little ugly."

This kind of wooden ox flowing horse with no head, only a torso and four legs is really ugly.

But ugliness is ugly, just be practical.

An Wen tried it, and after finding that there was no problem, he came to the complex.

Hundreds of wooden oxen and flowing horses, even if it is a simplified version, An Wen will not do it himself.

As long as this simplified version of the wooden cow flowing horse is integrated with the backbone technology to generate design drawings, it can be automatically produced, and he will make it himself when he is brainless.

"Do you spend 800 survival points to fuse backbone technology?"

"Sure."

Swish!

White light flashed.

Anwen didn't even look at the properties of the drawings, and started production directly, with a quantity of 200 units.

After closing the list of knowledge trees, An Wen clicked on the technology tree again.

"Neither math nor physics has been upgraded, chemistry can't be lit, biology can't be lit, and materials are ...... Well? Can the material be lit? ”

Originally, An Wen was only going to flip through it by the way, but he found that the first icon of the material list was actually lit up.

"Bronze smelting?"

An Wen clicked on the icon and found that this icon was bronze smelting, which is a technology for refining copper.

Without saying a word, just light it up.

In an instant, a wave of knowledge about extracting copper and refining copper melted into An Wen's mind.

"Huh? Can you go a little further? ”

The icon below is a bronze alloy, and next to this icon, there is a list of branches marked with bronze corrosion-resistant alloys...... Bronze memory alloy ...... Bronze wear-resistant alloy ...... Bronze load-bearing alloy ...... Bronze sterilization alloy ...... Bronze superconducting alloy ...... Further down there is no way to see it.

Anwen continued to light up the bronze alloy icon, and then the icon of the branch list on the side showed that it could be lit.

So what else is there to say.

The icons on the branch list also lit up one by one, until the bronze sterilization alloy could no longer be lit up, and An Wen stopped.

All kinds of knowledge about bronze alloys appeared in his mind.

"I seem to be going crazy."

Ten minutes later, absorbing the knowledge about bronze alloys, An Wen was so excited that even his eyes began to glow.

What is Copper?

For many people, copper is wire.

In fact, copper occupies a very large proportion in the current industrial system of human beings, and basically all industrial manufacturing products such as machinery and equipment, aerospace, automobiles and ships need the participation of copper alloy materials.

At the frontier of science, scientists have been researching copper until now.

"It's a pity...... The icon below can't be lit up, if you have knowledge of bronze superconducting alloys, it's really awesome. ”

An Wen muttered a little pity.

Man, he is not satisfied.

Closing the materialology list, Anwen continued to scroll down to see if there were any other lists that could light up.

As a result, he really found it.

Icons that couldn't be lit before in engineering can now be lit up.

This is the third list to be lit up after the two lists of Mathematics and Physics.

"I'm ready to graduate school."

After absorbing engineering knowledge, An Wen said that he had no pressure at all for his next graduate studies.

Keep scrolling down to see if there's anything else that can be shabby.

It's a pity that the energy column is still pitch black and can't be lit.

Sigh!

Ann Wen closed the list and sat on the ground.

"It's good to light up these technologies, but the question is, why can't they be lit before, but now they can?"

This made An Wen very puzzling.

Before, he thought that he would have to leave the novice village or find the next level so that these technologies could be lit up.

But now, he hasn't done anything, and the list of materials and engineering can be lit up.

Why is that?

An Wen recalled everything he had done in the recent past.

He doesn't seem to be doing anything special.

At most, it was to run out and pretend to be a wave.

He has always been very low-key, very honest at home, and has nothing else.

"Yes, yes, yes...... Bronze, I went to mine in the morning and dug up a piece of azurite. ”

Suddenly, An Wen thought of it.

The opening of the list of materials is definitely related to the fact that he has dug up a piece of azurite.

"Then the opening of engineering is related to the lighting of the material list, because most of the engineering knowledge lit up today is related to the knowledge of large equipment components.

Previously, these engineering icons could not be lit up because there was no material to support them, and the wooden material was not strong enough, while the bronze alloy could.

In this way, the opening of the list of technologies is related to raw materials...... No, that's not accurate.

It should be said that the opening of the list requires you to meet certain requirements, such as the discovery of copper ore, so the bronze technology in materials science is illuminated.

And then because of the bronze alloy, the engineering icon is lit up, and it's a chain reaction. ”

Thinking of this, An Wen has basically determined what the rules for the lighting of the technology list are.

But these are not the main things, because An Wen thought of another thing.

"In the morning I found a black pit in addition to the mine.

According to the analysis of the mine, then the black pit should be a coal mine. ”

Very excited!

The discovery of coal mines, does that mean that the energy list is lit up?
