"Didn't you come to me to say good things and ease the relationship between you and Bo Qing?

Then how could you come back without hearing my call?

Generally speaking, this is not in accordance with the rules.

Moreover, I know that you hate going back to Chang'an the most.

Chang'an's environment, there is no way to reach your level of hygiene.

You will come to tell me in person, it means that this matter should be quite important, and you don't want to let the people around you know, let alone let the people around me know. ”

Emperor Liu Heng waved his hand at this time, and let all the people around him retreat, leaving only Qian Rujun.

Emperor Liu Heng knew that the people around him couldn't deal with Qian Rujun at all, after the incident in Metroidvania City, as well as all the previous incidents, Emperor Liu Heng spent a long time analyzing Qian Rujun.

In the end, I was surprised to find that if Qian Rujun wanted to be unfavorable to the emperor, he didn't need any excuse to take the emperor's life surrounded by a large army.

So now it can be seen that Qian Rujun did not have any ill will towards the Han and the emperor.

Maybe for another emperor, Qian Rujun would have some other ideas, but for the person who is Qian Rujun's father-in-law, she doesn't have any thoughts that she shouldn't have at all, so the emperor is at ease at this time.

It's a pity that Qian Rujun was not by her side at this time, and she didn't know that the hostility she felt to Emperor Liu Heng before was true, but now it is true that the emperor has no hostility towards him.

"Father, you really know your son. ”

"If I don't understand you, can I make you so laissez-faire?"

Emperor Liu Heng smiled bitterly.

"I want to talk to my father about something.

This matter may be heard by the craftsmen of Shaofu, but others are not suitable to listen to it.

How many people know how many people can know, maybe the emperor will have to wait for the emperor to listen, as for the craftsmen, in fact, I don't know which craftsmen are suitable to listen to now.

The son still told his father about the principle of explosives. ”

So Qian Rujun told the emperor about the composition of the explosives and her efficacy.

Explosives are still a little strange to the emperor of the Han Dynasty.

Unlike Da Song, he may have to have a little understanding of explosives, but in their cognition, explosives cannot play a role.

The explosives described by Qian Rujun are not ordinary explosives, but burned to have lethal power.

Qian Rujun even knew that with these explosives, coupled with the improved blacksmithing skills in Jinmaicheng, in fact, the countries of South Vietnam could be recovered quickly, and there was no need to send too many troops, as long as there were a thousand well-trained firearms soldiers, they could be pulled over.

These 1,000 people must be well trained, otherwise they will hurt themselves before they hurt others.

The emperor smiled bitterly at Qian Rujun and said, "You always bring me a lot of accidents, explosives and such things, to me, are like the anger of the gods, causing people to suffer disasters.

But you also said that he could help you boil water and quickly bring fertile land to the Han.

Even building roads to bring so many benefits to the people, but you said that if it is not properly controlled, these things may overthrow my Han Dynasty, then you ask me to use it for you, this is too demanding of me!"

"Father, you know, even without your permission, I can use it as I please. It was out of respect for his father that he came to seek his father's consent.

The retainers are loyal and can shine on the sun and the moon. ”

Emperor Liu Heng knew Qian Rujun's intentions, and he had already put it clearly in front of him, if he wanted to believe it or not, of course he could say it at will, but it would be too hurtful.

But the emperor obviously felt that Qian Rujun really wanted gunpowder, but Emperor Liu Heng also knew that using gunpowder alone in front of the emperor would arouse the emperor's suspicion.

So Qian Rujun came to obtain the emperor's consent, and let the emperor know that if she took out such a thing as gunpowder, she was not afraid that the emperor would use it against her, but she would not use it against the emperor.

"Is it difficult to make gunpowder?" the Emperor sighed and asked a question that she felt was the most important.

Qian Rujun replied: "To make gunpowder is actually very simple, as long as the raw materials are obtained and some proportions are used, it can be made.

But the real way to make gunpowder exert its power is not the gunpowder itself, but other additional products.

For example, if we put water in a jar and seal the jug.

But we made the water in the jar keep rising, so that even water could produce power with an explosion, not even water.

We just sprinkle the powder in the air, in an airtight place, and put the flame at the right time.

Dust can also produce explosions.

Even it is not too difficult to operate than gunpowder.

It's just that the explosive power of gunpowder is greater than that of dust, and the explosion of gunpowder does not require a confined space, so it can be used in a large number of projects.

Because gunpowder is actually the most suitable for blasting stones, but what kind of influence will my father think about what can blow up stones?"

Qian Rujun described it specifically enough, Emperor Liu Heng only needs to imagine it, he can think of even a stone being able to explode, but if he faces people, the consequences will be unimaginable, but if it is on the battlefield, the biggest problem is that no one is forbidden to move.

And what you're going to explode is often very far away from you, and you have to find a way to wait for him to project it, and then it will explode after he has projected it.

But how easy is it to light a fire at such a distance?

Emperor Liu Heng said this question to Qian Rujun.

Hearing that the emperor had asked such a simple question, he simply took out a clay pot and asked someone to take out a cotton thread.

Then put a high concentration of alcohol in the clay pot, as for this alcohol, of course the emperor himself did not have it, but Qian Rujun took out a can of alcohol from her body.

For the emperor, "wine" is not too special a thing, but the wine taken out by Qian Rujun has a particularly strong aroma.

The emperor saw a pot of wine, smelled the aroma of wine, and felt that there was nothing special, but Qian Rujun put the cotton thread in the alcohol, and at one end of the cotton thread, let the cotton thread absorb the alcohol and put it on it, and then set the cotton thread on fire.

Then Emperor Liu Heng saw that it seemed that the cotton thread could burn endlessly, not as fast as usual.

Seeing the burning of the cotton thread, the emperor felt that it was not simple, and then looked at Qian Rujun with questioning eyes.

Emperor Liu Heng, he knew that Qian Rujun would give him a proper explanation.

Qian Rujun did explain to the emperor, but she didn't say too much, she found that in fact, the emperor didn't know, she didn't need to know the principle, she just needed to know what this thing could do.

So she explained to Emperor Liu Heng:

"It's a lead that ignites gunpowder, and we just have to get a long lead, light it, time it, throw it at the right time, and we can explode at a regular time.

Of course, there are other ways to make an object explode, for example, when something hits, it will break, and at that time there will be some shocks, and these shocks will cause the explosion to happen.

Also, if we put a lot of metal in a clay pot and put it together with gunpowder, when we ignite it and throw it to cause the pot to shatter, the pot is pressurized.

These pieces of iron will scatter out in all directions, and these pieces of iron, one piece may not cause fatal injuries to a person, but when many pieces hit a person's body.

Sometimes you get to places you shouldn't, and even because you're facing too many shocks, you won't have time to prepare for them.

That's when panic happens.

So I dare to say that if the people who have gunpowder equipment are advanced enough, with only a thousand people and well-trained, they can take South Vietnam. ”

Qian Rujun accidentally opened his mouth and told the truth.

"How long does it take for a person to train well?" asked Emperor Liu Heng.

Emperor Liu Heng's concern was obviously different from Qian Rujun's, so he asked Qian Rujun this question.

Qian Rujun didn't hide it, after a rough calculation, he replied: "It can be used in three months, it can be used in half a year, it can be an army in half a year, and it can be an elite in a year."

Of course, there are some people who are not suitable for the battlefield, so we have to eliminate them. ”

Qian Rujun had a hunch that Emperor Liu Heng would ask her for something.

However, Qian Rujun felt that the emperor's request was not too excessive.

However, Qian Rujun looked at Emperor Liu Heng strangely, and Qian Rujun trained the most powerful army of the Han Dynasty, wouldn't the emperor himself be worried? The army she trained would be imprinted with her shadow.

Qian Rujun thought that the emperor was very wary of her.

"Can you help me train a suitable army? If you can help me train a working army, then I will let you bring gunpowder to build a water reservoir."

Even if you want to do any project, as long as you apply with me, I will agree with you to use gunpowder to open up.

In fact, you are also doing these projects for the sake of the Han, there is only good for me, there is no harm, if you are prevented from doing it, I am a fool. ”

"Father, no one can say that Father is a fool, and even in the history of the ages, Father is the great emperor of our Han Dynasty. ”

Qian Rujun told the truth, this is what she later read about the history recorded.

Even tomb robbers did not dig up the tomb of Emperor Wen of Han.

Because there were not too many precious items buried in his tomb, he was not dug up because of the love of the people.

Of course it wasn't dug up, it was advertised like this, and no one knows if someone was digging some small holes underneath.

But this kind of record clearly shows that Liu Heng, the emperor of Han Wen, was a good emperor for the civil system.

But for the military general system, living in the era of Emperor Wen of the Han Dynasty can't help but be a little aggrieved.

However, when the Han encountered the invasion of the Huns, they did not let the other party beat and scold, but would gather troops to confront the other party, and even they had the ability to guard against the invasion of the Huns.

However, it can be known that in the era of the Huns, in fact, many of the Han people in the north were taken away by the Huns, because they found that the Han people were more servile and more industrious than them.

It's just that Qian Rujun doesn't want to agree with what the emperor said so quickly, she knows that what the emperor says is often a bargain with you.

At this time, you must bargain with the emperor, according to the emperor's words, you will definitely suffer.

Although Qian Rujun hates bargaining, it is a matter of her life and death, even freedom, and at this time she has to bargain patiently with the emperor.

Fortunately, there are relatively few things related to his life and nature after all, so Qian Rujun doesn't have much time to bargain.

Most of the time, you can use the high price to fool the past, or let the students of the school island come out to solve it.

It also has no impact on Qian Rujun.

She found that in fact, the only person who was most likely to influence her in this Han world was the insatiable emperor Liu Heng himself.

But you say that the emperor is insatiable, in fact, if you bargain with the emperor and give a discount, the emperor Liu Heng will still accept it happily, but you must be able to convince him.

For Qian Rujun, Emperor Liu Heng seems to enjoy this feeling of bargaining very much, because no matter what he does, he takes more goods and takes less, and Emperor Liu Heng is a beneficiary.

Emperor Liu Heng just wanted to bargain, after all, if he asked Qian Rujun to use more explosives to open up the mountains, there seemed to be no shortcomings for the Han Dynasty.

It was the emperor himself who was in danger.

"If you can, help Bo Qing take down the South Vietnamese Kingdom.

Otherwise, I would have seen that the king of South Vietnam was demonstrating at every turn, trying to prove his existence.

But I know that I don't have time to fight him, but now he is much more well-behaved, because the disappearance of the Xiongnu has allowed the Han to deal with the problems of the south in a comprehensive way, and these countries are now watching us. ”

In fact, Qian Rujun did not pass through these three countries, she also deliberately flew through these countries, as far as her observation goes, these countries are actually not composed of the Han nationality at all.

It's just that this land is considered to be the inherent land of the Han people in the Han nationality in later generations, and the people who live in it now look more like people on the Indonesian side in Qian Rujun, and I don't know where the people who live in Indonesia now will go when the time comes.

In short, these people will basically not be seen in later generations.

Han people can notice in later generations, whether it is people from various provinces or girls from the Northeast and Sichuan, they will find that their physique and appearance are very different, but there are still commonalities.

Qian Rujun noticed that the Han Dynasty's understanding of this place as an inherent territory was roughly based on where the scope of the Great Qin State was, and he thought that the place he ruled should be there.

But the Great Qin State has ruled these few places for a few years, so this kind of thinking is actually very domineering, but it is in the same vein.

Whatever the reason, it is both fortunate and unfortunate for this place to be considered an inherent land, because the people who live here cannot choose their own way of life.
