"One, two, three, four... Master! There is still a speed regulating mechanism!" on the first floor of the villa, a clear Lori sound of the little girl sounded outside.

Crisp and sweet, like wind chimes.

Survival and as long as mechanical aging, line shortage, or high temperature short circuit.

It takes more than half a day to find the root cause just for investigation.

Although when planning the route, I have been as meticulous and elegant as possible.

However, for complicated routes, transfer points, mechanical arms, and subsequent addition of new machinery, a new set of route planning must be done.

It will make the old lines stack with the new lines, just like the viaduct of the imperial capital. It's not that the old driver can't understand it at all.

"If only there were a differential at this time." Tang Zheng sighed softly.

The differential machine is known as the mechanical computer in the steam age. Through different conversion of 5000 digits, hundreds of thousands of different schemes can be calculated in a short time.

It's just.

Before Tang Zheng started to make the differential machine, there was a problem with the steam engine.

"Master! No! The material of the piston device of the third steam assembly is not enough!"

"Shifu, Shifu! The materials of the fifth set of crank connecting rod mechanism are also beginning to be lacking!"

"And!..."

Oh.

Tang Zheng rubbed his temples with a headache.

At this time, the shortage of manpower is reflected again.

If it is a modern factory, at least one or two employees will be equipped on an assembly line, which is used to troubleshoot mechanical problems and maintain the stable input of materials.

But now Tang Zheng is alone with LAN LAN. He can't be busy at all.

Neither Murphy nor the five tigers can do such meticulous "sewing".

The machines lacking materials were added one by one, and the problems of gears and copper wires were checked again. In a flash, it was late at night.

According to the power of the original steam engine, the envisaged output of one day is the accessories of 18 steam engines.

Even if it's only half a day today, there should be nine sets at the end of the guarantee.

But when the stars dotted the night sky, Tang Zheng counted the steam engine materials on his head.

Only enough to make three steam engines.

One afternoon, either the machine lacked materials, or the part collapsed, and then the fuel of the steam engine was insufficient. It was necessary to add new coal mines and water.

Tang Zheng is busy, but his efficiency is really average.

"Master... Why don't we invite someone?" the little girl suggested with a bowl in her hand and blinking eyes during dinner.

"No." Tang Zheng shook his head, picked up a braised lion's head and took a big bite.

Meat is wild mountain pork in the alien world. Some players are big pig farmers in the native world. When they come to the alien world, they still go back to their old business.

The taste is full, without firewood at all, that is, there is no greasy fat meat, and there is no dry lean meat.

In one bite, the fragrant oil drips all over the mouth, and then carries a mouthful of fragrant rice.

Um.

The little girl's cooking has improved by leaps and bounds.

After another sip of tomato and egg soup, Tang Zheng said.

"Please give them money for human resources. In addition, our current social structure is still very different from the original world. The national structure has not been established, the overall situation is relatively turbulent, and the people will never have a machine to be safe."

"Well, come on, master, make the robot!" the little girl nodded vaguely.

On the subject of human nature, LAN LAN has not been deeply involved in the world. She often thinks of things on the first floor.

However, the shortage of materials is indeed the most perplexing problem for Tang Zheng at present.

If this problem is not solved, even if the differential machine is made, a large number of machinery will be put into use, and the materials will be scarce every day.

After entering the steam age, many things can't be seen by one person alone, even if they are open.

Human beings have never relied on one person's efforts to move from ancient times to today's science and technology,

I looked at the statistical report of the little girl today.

At present, the most scarce is steel and gears, followed by plastics, and copper wires and tubes are also scarce.

The price of raw materials for these things is not expensive, mainly due to the value given by labor.

Iron is the raw material of steel and is not expensive. One virtual currency can buy two copies of iron ore.

However, the manually forged steel requires 10 pieces each.

Resin is not expensive, and the plastic board has reached 5 virtual coins.

Copper wire, gears, these are all the same.

Even if Tang Zheng throws all his 5.6 million virtual coins, it can only solve the needs at this stage.

"For the time being, the synthetic platform can be used to produce gears, steel and plastics all day. According to the current Xinri calculation, it can produce more than 100000 copies a day." Tang Zheng calculated a little.

But this is just the weight of a material.

Just gears, steel, copper wire, copper pipe, plastic.

Here are five.

When it comes to the consumption of gear props alone, the minimum 3W share should be guaranteed in a day.

Not enough.

Let alone expand the scale of the assembly line, the materials will only be more scarce.

"That's right."

Suddenly, Tang Zheng thought of a prop.

It was a reward product in the iron age, because the effect was unknown at that time, he never took care of it.

Later, when the version was updated, the system was mentioned once, as if it could imitate the molecular structure.

Tang Zheng turned over from the item column.

Soon, a colorless and transparent square crystal appeared in the palm of his hand.

[memory crystal (different) (excellent level ★★★)]

Properties: it can simulate the molecular structure of any primary material and change its molecular morphology.

Description: all beings are equal!

……

It seems that this is a special material from another world.

The effect is really powerful.

When it is placed in the hand, it can hardly feel the weight.

But the shell is very hard. No matter how soft Tang Zheng pinches or holds it hard, there is no way to change its shape.

Tang Zheng tried to take out a piece of steel and put the memory crystal on the steel.

Suddenly, Tang Zheng's pupils were slightly bright.

At the moment when the memory crystal touches the steel, it is like melting ice cream on the road. It turns into a soft liquid and spreads in all directions towards the steel.

It spread faster and faster. Just half a minute later, two pieces of steel with exactly the same shape, color, quality and hardness appeared in front of Tang Zheng.

Reach out your fingers and tap the steel plate to make a "bang bang" crisp metal percussion sound.

What surprised Tang Zheng most was that the memory crystal just now didn't run out!

The remaining liquid seemed to form a pulse, and soon turned into a solid cube under the eyes of Tang Zheng.

If it wasn't for the light refraction from it, Tang Zheng really didn't find that it had been lying quietly on the ground.

Picked it up and looked at it. It was only about one tenth smaller than the original size.

"Hiss..." Tang Zheng smacked his tongue slightly.

How dense is the density of this special material

Only when the number of molecules contained in the material is very high, can there be 9 / 10 left after consuming so many molecular structures to simulate the steel plate

"Good thing!"

Absolutely good thing at this stage!

Solved the urgent need of Tang Zheng material shortage!

If you remember correctly, its output can only be obtained in the eight forbidden areas and when you get various task rewards.

It's unrealistic to get it randomly by reward.

So

The only choice left is the forbidden area.
