Chapter 74 Machine Tools and Packages

At night, Su Zhen picked up a quill pen and kept writing on the parchment roll. Pen, fun, pavilion www. biquge。 info

List of research projects of the Faculty of Science and Technology:

Wind looms, wind looms,

In the case of the eastern territory, the river has been frozen for several months in winter, so naturally there is no water power. But fortunately, the wind resources are indeed abundant, especially the wind camp, which has not stopped all year round. The meal had to be eaten one bite at a time, so Su Jin interrupted and asked these people to research a simple wind power device first, and then go to study the steam engine.

Preparation of adobe houses, papermaking, compass, movable type printing, textbooks (architecture, mechanical construction). (Note: Song Yuhua personally organized.) ）

The weather here is not suitable for brick houses, not because the cost is too expensive, but... It's too cold. The thermal performance of a brick house is too poor. Therefore, what can really be used to live in is a relatively low adobe thatched house. This kind of house warmth is barely enough when the wolf is crying, and the cost is extremely low. The technique used in adobe houses is also very simple, and only needs a little guidance.

As for igloos, this kind of house can only be lived in for 50 days, which is not a long-term solution after all.

These four things exist in the empire, so there is no need to study them at all, except for the movable type printing Song Yuhua is a little unclear, the others are all very familiar, so these four things Su Zhen is ready to let Song Yuhua tinker out.

Cultivation techniques, textbooks (physics, biology, chemistry) preparation. (Note: Aurora personally organized)

Regarding the shed cultivation technology, Su Zhen actually didn't have much expectations, first, there were no seeds to carry here, and they needed to be purchased from the middle of the wolf's cry, and second, there was no plastic at all. However, thinking that Aurora takes the little princess around every day, abusing magic in all kinds of ways, and the most terrifying thing is that the little princess seems to have traces of being damaged, Su Jin feels that it is necessary to let Aurora do something.

Coal furnace, efficient mining of coal mines. (Note: Zhou Ke personally organized)

The coal stove is a very convenient tool that saves time and is efficient. As for the mining of coal mines, Zhou Ke, as a talent in this area of the empire, is naturally very familiar with it, and it is most suitable for him to be handed over.

Writing this, Su Zhen's face became a little more solemn, and he continued to write on the parchment scroll:

Artillery manufacturing, machine tools (lathes, planers, grinders, boring machines, punching machines) (note: Su Zhen personally organized)

If the steam engine was the core of the entire first industrial revolution, then the technical level of the lathe was the key to the manufacture of the steam engine.

What is a machine tool, it is a machine that makes a machine.

For example, the cylinder of a steam engine, this thing can't have a metal object of that size and shape! Therefore, it is necessary to process the initial irregular metal and make it into a specific shape through cutting, grinding, stamping, etc., which is called a lathe.

To put it bluntly, lathes are the mother of industry. Without qualified machine tools, there would be no industrial revolution!

In this regard, Su Zhen naturally does not have no foundation at all, whether it is Song Yuhua or Wolf Cry locally, they all have a certain machine tool foundation, of course, this foundation is still a big gap from being able to make steam engines.

But this Su Zhen is also very difficult, about the manufacture of machine tools, to be honest, how can he know so much, in this regard, he is not as good as Song Yuhua!

But even if he is not as good as Song Yuhua, he must come in person, there must still be a few skilled craftsmen who cry wolf, and when the time comes, try a few more times, maybe it will be done.

The other one is artillery, which is not that difficult. The key to artillery is the manufacture of the breech.

Think about what is the key technology of an artillery.

It's the breech, not the gunpowder! The gunpowder is strong, but the quality of the cannon chamber is not up to par, and if the cannon is hit, the iron bullet is not fired, but the cannon chamber is blown up! Isn't that just for nothing?

The same goes for muskets.

Think about it again, how to make the gun chamber, and what was used to make the hollow steel tube type of cannon chamber in ancient times.

Machine tool?

No, this is not made with a machine tool, but Su Zhen knows a little bit of the technology of making cannon chambers.

In fact, it is very simple, using different metals with different melting points.

The specific general steps are as follows, first make a copper stick, which is so easy for the craftsman who cries wolf to cast weapons! It's nothing more than changing the size of the mold and pouring the melted copper into it. Of course, there are still many details to be mastered.

Then came the crux of the matter, heating the steel from which the bore was cast until it melted into a liquid. (Current wind turbines and coal use can already reach this temperature.) ）

Then the molten steel is poured onto the copper rod to cool, here a little skill is required, because of the instability of the molten steel, and the gun chamber needs to be relatively thick, but this is not a difficult matter, it is nothing more than a problem of a new mold and an old craftsman.

After the molten steel has solidified and formed, the steel mixed metal is heated to a temperature. This temperature is just over the melting point of copper and less than the melting point of steel.

At this temperature, the copper quickly melts into water and flows out, leaving only hollow steel.

And just like that, a newborn cannon chamber was made!

The bore of the cannon has been made, will the shells be far away? As for whether the shells are hollow solid or some other trick, that's a matter for the craftsmen!

This method can be used not only to make the breech, but also to make steel pipes!

After thinking about what was missing, Su Scar entered the Elemental Tower again, and according to Su Scar's estimate, he should now meet the conditions for the Elemental Tower upgrade.

First, his cultivation had reached the intermediate level of a master;

second, his actual control of the territorial level exceeds 10,000 square kilometers;

Third, his actual controller population exceeds 100,000.

Sure enough, as soon as he entered the Elemental Tower, the system's projection text reminded him that he had met the upgrade conditions of the Elemental Tower.

Detected that the host has met the upgrade conditions of the Elemental Tower, and the Elemental Tower has been upgraded to lv3;

The number of cultivation rooms on the first floor was expanded to 1,000, the second floor to 100, and the third floor to 11.

Third floor!

Su Zhen was extremely looking forward to it, and quickly walked up to the third floor.

There is almost no difference between the third layer and the second layer, but there is nothing more in the cultivation cheats, and there is still a master-level magic energy catalytic furnace in the center. Su Zhen walked into a cultivation room with some disappointment, hoping that this would not disappoint him.

After entering the cultivation room, the scenes and sounds were still familiar.

Please select the type of cultivation?

Mage!

Please choose a cultivation cheat?

Looking at the row of cheats projected in the air, Su Zhen decisively chose the basic magic ice!

Although his thunder-based talent was also legendary, Su Zhen decided to master the ice system's super demon, the Ice Whisperer, first. As long as he masters the Ice Whisperer, his strength will undergo a drastic change.

Regarding this Ice Whisperer's super demon, Su Chen's eyes have been hot for a long time.

What followed was the same scene as the second layer, and there was only extremely pure ice magic energy left in the entire cultivation room.

Wait, it seems to be a little different.

By the way, the concentration, the concentration of magic energy here is actually twice as much as magic energy!

It's just incredible.

Just think about the effect of cultivating and practicing magic energy at twice the concentration.

The speed is simply doubled, and some bottlenecks can be easily overcome.

Feeling this rich ice-based magic energy, Su Zhen was so excited that he began to enter the cultivation room, although he kept rubbing his hands from the cold.

After Ye Ziming and the others learned that the third layer was opened, they unceremoniously came from the second floor to the third layer one by one.

Although the number of cultivation rooms on the third floor is not enough, if it is divided into night and day, it is equivalent to having 22 cultivation rooms, which is definitely more than enough.

As soon as they entered the cultivation, these people immediately fell into it obsessively.

It was just one night of cultivation, and Su Zhen achieved double the usual effect. Originally, according to Su Zhen's estimate, it would take at least three months for him to become a high-level mage. But now it is estimated that it will only take more than a month! It may be because of the high concentration of magic energy, Su Zhen has not been able to find a clue these days, and the realm (1/2) of the first layer of the Frost Decree actually has a clue.

Frost Decree: All ice mana costs half (1/2). After releasing three Ice spells, one Ice spell (2/2) can be cast instantaneously.

According to Su Zhen's estimate, within a week, he will definitely be able to reach the first level of the Frost Decree!
