At this time, Qian Rujun set up the iron-making furnace in the space.

See if contamination will occur.

Placing the iron-making furnace in the space, in addition to reducing the time consumption for the students of the school island, and allowing them to produce without being fixed in a certain place, the most important thing is that he wants to see if these polluting things will continue to be polluted if they enter the space.

Because there were a small amount of polluted things in the space before, and these things would be covered by the space in an instant, analyzed and dissociated, so if these polluted things could be dissociated in the space, then in the time that Qian Rujun lived, maybe he would put these polluted things into the space to produce, and the students of Xuetang Island might have to have the task of production, instead of concentrating on studying their own knowledge in the space, or maybe he could bring some people from the outside to work in this place, but the people who came in might not be able to let them out。

In addition to the high-temperature combustion of coking coal, the most important thing is to produce some gases, and these gases tend to make the surrounding environment black, so most of the factories put the discharge pipe very high, and want to let these pollution be discharged to a relatively distant place, without polluting their living space, but other people also have the same idea, so when these iron-making furnaces are more places, the air is often very bad。

In the era of the British Industrial Revolution, Birmingham, the center of industrial production, became black again because of this, and was called the black country by others, and it was difficult for any industrial center to escape the fate of black at that time.

Standing next to the iron-making furnace and looking intently at the blue sky, will it be enveloped in black smoke, or where will it fall when it drifts out?

However, after watching it for a long time, Qian Rujun still didn't feel anything, it seemed that after these black smoke drifted out, they all disappeared directly, because everything in this space, unless it was outer space, otherwise Qian Rujun could more or less feel the changes in the space, if it was originally unchanged, she could not feel it, but as long as there was the slightest change, she could feel it.

Qian Rujun can note that in the past, it can be said that as long as pollution is formed, it can be isolated in an instant, unless the source of pollution is solid, and when the solid is buried in the soil, it will be decomposed by the soil.

In fact, the so-called pollution does not pollute, these things are originally in the soil, is one of the components of the earth, the reason why pollution is because its concentration exceeds the warning value that it should have, if it is evenly distributed on the earth, it does not constitute pollution.

Everything that human beings produce is originally taken from the earth and will return to the earth.

Qian Rujun thinks that the method of dealing with the bookshelf space should be to distribute it evenly, but if a large number of iron-making furnaces start to be made in the space, then you have no way to avoid it, but there are only small-scale iron-making furnaces for some people in the Han Dynasty to use, and it is estimated that it will not cause too many problems.

It's just that when the weapon is built, the Emperor of the Han Dynasty can't turn a blind eye, and the emperor will definitely ask Shaofu to learn to smelt steel, and it becomes impossible to stop the sky from turning black at this time.

Once it was discovered that this method would make better steel than ever before, and that it would also be less labor-intensive, the price of iron would start to fall.

More weapons will appear in this era, and everyone takes wearing a weapon for granted, just as everyone in the United States can carry a gun, if guns are not controlled in Dahan, it may become too simple to take another person's life.

If the emperor really wants to make it in large quantities, then he must warn the emperor that he cannot let everyone get this weapon, even the people around him, he must think carefully, as for the craftsman, it may be easier to obtain the weapon than others.

Perhaps the craftsman will be the first to use weapons to claim power for himself.

Compared with swords and other things, guns are much simpler to operate, they don't require a lot of strength, they don't require much skill, as long as they can shoot bullets, the guns made by Qian Rujun are much better than the most primitive guns.

Anyone who has already been obtained, you can grab the gun and shoot it out at will, basically in one direction, if it is at close range, you don't need to aim at all.

It's too difficult to miss.

When the training was on the thirtieth day, 100 guns made by the students of Gakudo Island were delivered to them.

As for why it wasn't two thousand guns, it was because Qian Rujun hadn't been able to gather all the students of Xuetang Island together until now, and they had other work to do, so they couldn't do it wholeheartedly.

Qian Rujun can only go when they try to allocate time to build guns, Qian Rujun is even mentally prepared, when guns, if a thousand guns have not been built in three months, then he will start to go south with people, in short, when they go to the battlefield, the guns must be built, as for a hundred guns, in fact, it is enough to do beginner training.

Divide the 12 hours of the day into 12 equal parts for training, so that they can become initially proficient.

The students of Xuetang Island have already done it, and after they are proficient in making guns, the speed of making them will be faster than before, because there is more infrastructure to be done in the front, but the speed of fifty guns a day can be increased in the back.

Qian Rujun thought that in the end, they might be able to make a hundred a day, but now they are just unfamiliar.

In a month's time, the group of troops trained by Qian Rujun has been very impressive in terms of mental appearance, but the instructors are still very worried, because they only run during this time, and they have not done martial arts training, and when they encounter the enemy, they may collapse directly.

Moreover, Da Sima did not directly let Qian Rujun train his army, and was very worried that Qian Rujun did not let the recruits do some chopping training, as well as some martial arts coping training.

On the day Qian Rujun fired the gun, all the eyes were focused on this gun, although there were only 100 guns, but when a hundred people were selected to launch this gun, it created a very big shock.

Those who used guns for the first time were rewarded with black green.

The shoulder blades of both of them were directly broken, and in the Han Dynasty, a broken shoulder blade was a big deal, so Qian Rujun found a student from Xuetang Island to train the newly recruited female nurse.

"It's so undeserved for women to come to see these soldiers, men and women should be separated, not to mention that these filthy things shouldn't be seen by women like that. ”

There are people on the side of Da Sima who jumped out to fight back against Qian Rujun's approach, these people are people who have some loyalty to the imperial court, and have some psychological obstacles for the excessive expansion of imperial power, they want to let the emperor know that the heart army should be built according to the original appearance, and the original army is already strong.

Although the imperial court said that it was the Liu family, in fact, there were several big families in the imperial court, although the Liu family had the right to let other families rise, but if these big families were provoked, maybe the political power of the Liu family would be turbulent.

Imperial court politics is originally a kind of balance, at the beginning of the imperial court, the emperor himself will have great power, but slowly with the development of the court, the balance will be broken, the courtiers will slowly suppress the emperor, for the emperor's position, in fact, not everyone wants these courtiers to be able to take power.

They understand very well that if they get to that position, it will not be easy to come down, and often the entire family will be destroyed, and the best position is actually a powerful minister, a powerful minister who can shake the government.

In this position, they can attack and retreat.

As long as one person in the family becomes the emperor, the whole family is at the peak of power, but it is also in a crisis of life.

When Liu Bang became an emperor from a commoner and opened the era of a commoner becoming an emperor, he changed a shackle of the times and made everyone think that maybe he had the right to become an emperor himself.

That is to say, everyone can become a rebel, which greatly created the emperor's crisis, I heard that there are very many people who rebel in the Han Dynasty in ten hundred people, and the Han Dynasty has an endless crisis of rebellion.

However, because the contact was too difficult, most of the rebellions were not able to sweep the entire Han Dynasty, although the Han people were relatively few, but the population density of the Han was also low, and if it was a place with a high population density, it was actually relatively easy.

The existence of guns in the rebellion is actually a very light and simple thing, and the emperor may have to do more difficult security work when he travels in the future than now, because the range of guns is very long, more distant than bows and arrows, in such a situation.

In the future, those who become emperors will inevitably encounter countless assassinations.

Of course, if the power of the family is strong enough, the emperor dies, and it is good to replace it with a person, who can immediately suppress the rebel forces, and if a gun can be effective, there must be bullets and the production of bullets is more difficult for the Han people, but if the emperor wants to make the gun a must-have for the army, then the bullet will also become something that is easy for people to get.

Da Sima's people naturally will not be women, the only men who can mix in the Chang'an Women's Academy are Qian Rujun's students and instructors, and it is Qian Rujun who is going to do the test firing of guns, of course, it is impossible to be in the Chang'an Women's School.

They went to the outside of Chang'an City and found an open place, and this open place belonged to the Qian family farm, so Qian Rujun wanted to use this place to do something, and the Qian family farm had no right to object.

As for the farm, the grass looks green, and it is a place that people from the suburbs often visit.

This is a tourist venue reserved for people in the vicinity of Qianjia Farm, and there are many such places, most of which are distributed in all corners of Qianjia Farm, so that everyone can rest after work.

There are still many chairs to sit on, so in the end, these places are no longer from the Qian family's farm, and some ordinary people will come to this place to go green, so when they heard that Qian Rujun took her soldiers and was about to come to this place for a gun test, many people joined in the excitement and followed.

Although Chang'an City is large, it is not always lively to see, and most of the time, even Chang'an, still belongs to a relatively quiet era.

When a hundred guns were fired in a volley, the trained soldiers were still sparsely shot, but they were used to cooperating with the people next to them, so although they were sparse, they could still see the consistency of the guns.

When a hundred guns were fired in a short period of time, it brought a sound that shook the people of Dahan.

The people sent by the imperial court officials originally wanted to do something to make trouble, but this sound made them scared too, they were afraid, if the gun was not aimed at the target in front of them, but at them, they would be scared to pee their pants.

But when the gunfire ended, they looked at the target and laughed, the gun hit the target did not have a few shots, most of them also went to other places, if it was not for Qian Rujun forbidding people to build the front of the soldiers, but forcing all the people to stand in the rear, at this time even the people standing on both sides may be injured by stray bullets.

However, Da Sima's subordinates, they have also been tested on the battlefield, and they know that on the real battlefield, it doesn't matter if they take the time to aim, as long as the guns are fired forward, no matter what, they will always strafe one or two people.

But they still noticed a weakness in the gun, and someone said, "The wound is too small to make the other person bleed a few drops?"

The man said disdainfully.

These men had all been killed on the battlefield, and they knew that they had to have enough blood left, or that their heads had to be cut off to kill the enemy, and as for digging a few holes in the enemy, it seemed that nothing would happen.

"Although the hole is small, but hitting the heart, or the head, can directly kill the opponent, you can notice that the target is hit everywhere is pierced, which is different from ordinary sword wounds, so we have to let these people practice aiming so that the bullets will not be wasted. ”

If they really don't know when they came to Da Sima, their rear, as someone who came to find trouble, would inevitably be a little embarrassed if they were discovered.

But when facing Qian Rujun, they must lower their posture, otherwise they will be suspected of insulting the royal family of the Han Liu family.

"Then we have only finished a hundred guns, and new finished products will come out one after another. In fact, you should be able to know the power of the guns, and I don't mind you reporting it to the Emperor. ”
