Daqin Engineers

Shen Bing wants to think about it, but also can't guess what Zhao Gao and Li Si have something conspiracy, so I can only make it.

Shen Bing's heart is thinking:

"It's just like the generals of history, and after the death of the death, Zhao Gao and Li Siki will give the sacred sacred sacred!"

"If it is before, you still need to worry."

"But now ... When Shazhou has been controlled by Qin Jun in his hand, it is nothing to worry."

"Shazhou has a rigorous and Yumen's defense, and the inside is a narrow Hexi corridor."

"And the Qin State is still thousands of miles away."

"As long as one is standing ... At least Shazhou can stay!"

Of course, this is just a conservative idea. In fact, more than 100,000 military power in his hand now adds a rider and the advantageous equipment, and there is a force in the rest of the Qin army.

After a few days, I owe it to report that the iron core copper cannon has produced.

This is more than a few days ago, but this is not surprising ... It is not surprising that the casting of the new iron is so good, and the casting method is just putting the new iron and then pouring the mold.

Shen Bing did not hurry to accept acceptance, but let Wang Hao take a few pharmacy.

The so-called "pharmaceutical bag" is a gunpowder package for the fire.

Unlike other gunpowder, the gunpowder in this pharmacy is no longer equivalent, and the proportion of nitrogen is also like modern black powder, accounting for three quarters.

Shen Bing did not want to make a good film to the Madil, but it could not play a role due to lack of power.

When I rushed to my iron workshop, I rushed to the iron workshop by the carriage, I saw that I owe the fire door.

If this is the difficulty of this casting, it is the fire.

Because this fire door is required to leave a small hole on a thick gun.

This hole cannot be too large, and it will be severely leaking to reduce the number of power in the artillery.

Such a small hole cannot be done with a pepstration ... The pepper is only suitable for large-scale forming, if the mud, such as a slender strip, I am afraid that the two lower half is poured into the iron water.

On the other hand, there is no drilling tool at this time. After you want to make it, you will take a small hole on the gun, I am afraid that it is not a few months.

I wanted to have a way for this:

He first tries a tin, then roll the iron tape into a hollow tube, which is closed on both ends of the graphite powder.

After the iron water is cast, then insert this iron rod into the mud mold ... The iron pipe has a certain thickness, which is not so easy to melt in the iron water, so it can keep the approximate position and integrated with the iron gun. .

The graphite powder in the iron pipe has a melting point of up to 3600 degrees, which is much higher than the 1500 degrees of iron water, so it does not melt and open the iron.

After the mold is cooled, as long as the iron tube is shoveled out of the grapse powder, a slender small hole is formed.

Introduction, Shen Bing is not ambiguous, and they can always use the easiest way to complete the seemingly complex thing.

However, I owe it to watch the iron wire on the wooden rack, I don't understand, asked a question with Wang Hao:

"General, what is the use of this copper iron tube?"

"This material is more than 700 pounds, I am afraid that it is difficult to use for battlefield ..."

Qin Shi's more than 700 pounds actually only more than 300 pounds.

The reason why Shen Bing did not do it more, not because there is no bronze iron, but because of thinking that it is going to pull it in the desert in the desert ... More than 300 pounds is the load limit of the camel's long-distance transportation, it is not used There is not much problem in the carriage.

Shen Bing did not explain much, just took a cylindrical medicine bag in his hand.

Of course, this is to use a wooden stick to smash the medicine to the pharmacy.

Then put a solid iron ball in, and use a wooden stick to top it to the bottom to prevent it in the middle.

Then take a long needle from the fire door to explore the pneumatic pack, and then insert the long need and then insert it early to make a well-prepared fire ... This fire can actually use the gunpowder directly, that is, long acupuncture After breaking the medicine, I poured into the gunpowder from the fire.

Since the fire is just a small hole, it will be filled with gunpowder soon, so it has formed an internal and external ignition channel.

But it is obvious that the guides are much safe than the gunpowder.

Because when the operation is not properly operation, it has been scattered, and it is easy for a lone that it will take the accident.

On the other hand, it is basically one point to fire, and the fireflower will be delayed, so that the gunner like this has time to avoid.

The ancient soldiers who have never operated the artillery will certainly have this experience, so I would rather spend more time to make a guide.

Everything is ready to be properly, and Shen Bing took out the fire in the eyes of the people.

It is necessary to ignite is blocked by Wang Wei:

"General, these small things will be the next generation."

"The generals are still avoided!"

Wang Hao knows that the medicine package is gunpowder, that is not a trouble, so letting Shen Bing avoided.

Shen Bing did not refuse, after all, he didn't sure this artillery could not be successful. If it is because the manufacturing process is behind the first hair?

However, if you think about it, you should let a dear point.

But it is already too late, just when I think so, Wang Hao has blown fired fire and then goes to the fire .... Guoju as a "Sso" jumping Mars into the gun body.

After a while, I only listened to the "bang", and everyone saw the storm of the gun body ... but the gun stand was unstable.

What I think in Shen Bing is that it should improve the gun rack, or install a pair of wheels to make it better to consume the rear seat instead of death.

Moreover, it is also easy to play the battlefield motor after installing the wheel. For example, you can use the marginal drag directly.

At another look at everyone, I still have a wooden chicken look at the gun, so half of them reacts, and ask for a confusion:

"The general, is it this?"

"This matter ... is it a big rang to scare the enemy?"

Shen Bing "" has a "", then realize that they don't know that shells have emitted in this process.

This doesn't blame them.

The speed of shells flew out very quickly, and even a thick smoke, plus the loud noise, the three souls were thrown, and they would pay attention to there is something from the gun.

Shen Bing smiled, said to the guard on both sides:

"Two hundred steps forward, go to find the projectile!"

Privalented:

"Playing the pill?"

"The generals said that the iron ball?"

Shen Bing didn't have a good job:

"It is iron ball, I find it out!"
