Qi found Qian Rujun, and the atmosphere in the palace suddenly became leisurely.

It seems that the emperor must have been very anxious before, for him, the existence of Qian Rujun is related to whether he can return safely.

For a special creature like the Emperor, he wants to be on the battlefield on the one hand, but on the other hand, he must take care of his life. In addition to wanting to enjoy the supremacy of the emperor, the main reason is that the country, every time an emperor is changed, it is a toss, in the past, Emperor Liu Heng was also worried that after this labor and loss of money, it would make the Han breathless, but after having more income, he felt that it would not be worse than when Qian Rujun appeared.

After all, Dahan has made great progress. At least, in the new crop areas, food prices are falling.

Because the new crops are more productive, many people are gradually able to avoid hunger.

"If you had found me a month ago, you would have had time to prepare for your trip, but now there is only half a month left, and we are about to go. Emperor Liu Heng said to Qian Rujun. Regardless of Qian Rujun's confused expression.

"Where are you going? Is my father going to Shanglin Yuan to rest? The temperature on the outskirts of the city will be one or two degrees lower than in the city, and it is colder in winter, so it is better to stay in the city, or go to the dormitory of the Chang'an Women's School. ”

Qian Rujun didn't notice for a while, but he actually used the temperature measurement unit of later generations.

But Emperor Liu Heng didn't seem to care much about this, so he didn't hold on to it. But there were other things that caught the emperor's attention.

"Isn't your Chang'an Women's School stopped by men, and I can also go?" Emperor Liu Heng asked curiously.

"It's good to let the head of the school give up her dormitory, she has a separate small dormitory, which is not connected to the other dormitories. The facilities in the women's school are very good, and you are not as comfortable as the head of the school here. ”

Qian Rujun hurriedly remedied. She was originally thinking of her penthouse dorm. If she is gone, she will naturally disguise the students of Xuetang Island and let her pretend to be Liu Yi.

Liu Yi was not a real person in the first place.

"Okay, I'm not kidding you, you should know where I'm going. There's no way you can stop me from going. ”

Emperor Liu Heng suddenly stood up. The emperor stood up, and Qian Rujun was embarrassed to sit in front of the emperor.

Qian Rujun really wanted to say that she really didn't know, but as a goddess in the eyes of the emperor, she really couldn't say that

"Father's weather is cold, and it's not good to go out at this time. ”

Qian Rujun had no choice but to talk about him leaving and right to say this paragraph. This sentence is not wrong with this season.

What she said is right, when she goes out during this period, she really can't do anything.

It's so cold that it may snow soon.

During this period, if people go out too often in winter, their toes will be frostbitten, because few people in the Han Dynasty have complete shoes.

Even if there are shoes, most of them are straw sandals. Not hardy. Therefore, the people generally do not go out in winter.

"If you don't go on the expedition at this time, when will you wait?" Emperor Liu Heng said menacingly.

"It's not easy to walk in the cold. Qian Rujun persuaded, she finally knew what the emperor was thinking, and Emperor Liu Heng actually wanted to use the winter to go on an expedition, which was really unprecedented.

In winter, the tribes in the north are indeed in the cat winter, and there is no way to assemble. This is the time when Shan Yu in the north has the least people around him, and it is also the most difficult to gather.

But in this case, even if the opponent is defeated, there is no way to cause actual damage to the opponent's strength.

In the spring, these people gathered together again and continued to raid in the south, unless the Han people were able to emigrate to the north. But the opponent's territory was completely occupied.

In this way, the strength of the North can be detracted. But there is no Great Wall in the north, so it is not easy to defend it.

And although the peasants of the Han Dynasty often said that there was no field to cultivate, in the Han Dynasty, in Qian Rujun's view, there were fields everywhere.

However, Qian Rujun also didn't want the Han to do his best to fish. The mountains are developed with them as fields. It's better to be a place to go green.

It needs to be organized, but it should not be overdeveloped.

However, the population of Dahan is really not enough, and it is enough to even develop the territory of Dahan.

The people of the north are able to give birth, and they can give birth to a bunch of cubs each time, and when the population increases, they will start to conquer everywhere, and then reduce the population.

Maintaining such a large population forever, survival of the fittest, is enough to cause harm to the Han people.

As long as there are 10,000 men, they can fight south. The Han people who farmed the fields were harvested as cattle and sheep.

For the agrarian people, it is really difficult to deal with the ethnic minorities who can fight on horseback and love to rob.

She could not see the benefits of going to the Xiongnu during this period.

"One of the crops given to us by God is called potatoes, and we are growing a lot of them in the palace. And it can be taken around to plant, and even our experiment is out of the Great Wall. Found to grow well even in the cold north. Farming doesn't have to be too laborious. ”

Emperor Liu Heng said. His eyes lit up, and Qian Rujun knew that he was definitely thinking more than he said.

"Father, do you want to?"

For the first time, Qian Rujun felt that the emperor was also such a bold creature, and she felt that the emperor was afraid of the east and the west, and pursued overall stability in everything. Plan before you act. But now it seems that when the emperor has no one to manage, he will not obediently stay in the palace to work.

"It's not easy for them to get together, so we can just play games with them and we don't have too many people. I was ready to set out with more than 20,000 cavalry. Raising soldiers for a thousand days is used for a while, and the horses you have raised, I have already tried them, and they are very good, they can run fast even in freezing conditions, and they have hooves to protect their feet, and they don't have to worry about frostbite on their feet. ”

Emperor Liu Heng brought the thoughts in his heart one by one, and it was estimated that the emperor was not so honest with others and said a lot of things.

What can Qian Rujun say, she knows that the emperor already has a plan in mind, and what she doesn't understand is what the emperor wants to go out to fight for her, why do you have to take her with her, she doesn't seem to show belligerent tendencies.

Putting the problem in your heart will not be solved, so Qian Rujun asked.

The emperor looked at Qian Rujun, smiled, and said:

"You still don't know something? I thought you were omnipotent! I asked the savages, and now you can't be savages. It should be called my dragon and tiger guard. The warriors of the Dragon Tiger Guard said that as long as the princess was there, they were not afraid of starvation. Therefore, after the stopper, the issue of food will be in your hands. ”

After Qian Rujun heard it, he was immediately furious, this is too cheating.

No, it should be said that it is too much of a daughter.

"......" Qian Rujun couldn't believe that she was actually cheated by those who were brainwashed.

Although he didn't say the space, he said that Qian Rujun was able to get food for 20,000 people, which was enough to make people sweat.

Fortunately, the Emperor himself didn't seem to know much about what the savages were really saying.

"The food was given to them by the gods, not by me. Qian Rujun wanted to say that the food they ate for more than ten days was not provided by her. There are no three hundred taels of silver here.

There was no way, Qian Rujun could only explain like this, if the emperor knew that these foods tasted the same as the space food they often ate, she would be finished.

Sometimes you want to be good to a person, but you have to hide it from him, once he finds out a lot of things, you want to be good to that person, and there is no way, because the other party will doubt you, and even despise you, at this time, if you think about your own safety, you have to eliminate the other party.

In short, according to Emperor Liu Heng's meaning, she had to go out with her this time. For Emperor Liu Heng, Qian Rujun is a guarantee to go out, since he is in heaven and thinks that Liu Heng is the true son of heaven, then he should be given some benefits at the right time.

It's just 20,000 people, which is not a big force for the Han Dynasty, and for the emperor, this is not an official expedition, so he did not announce it to the world, but discussed with the crown prince for one night and prepared to set off.

That night, Qian Rujun was not released, but was forced to stay in the palace.

"If there is something about food and grass that needs to be understood and solved. I'll have the officer in charge report to you all the way. ”

Fortunately, Qian Rujun and Liu Heng have the status of father and son, and nothing ugly happened. But she still felt that she was not fit to live in the palace.

Now there are more children in the palace, and there is more yang, but Qian Rujun just feels that this is not the place where she should stay.

Unlike ordinary families, for Emperor Liu Heng, even the women who belong to him are unbelievable, and there will be no more than five people he can trust.

These five people can go from believing to not believing at any time because of the change of circumstances.

Qian Rujun felt fortunate that he used his spirit to transmit sound, and he had already ordered the people in the space to do things.

It's just that in the palace, Qian Rujun can't let the students of Xuetang Island out to pave the cement road, so he has to find someone else to do it. Fortunately, the laying of cement roads is not a big deal.

It was only one night, and the students of Xuetang Island brought out all the work plans, Qian Rujun thought about it for a long time, and decided to hand it over to the head of the Chang'an Women's School to do.

Nominally, in terms of the travel of the students of the Chang'an Women's School, it can smoothly communicate with several lively places, and the Chang'an Women's School is not far from Chang'an City, and it is reasonable to build the cement road to Chang'an City!

However, the outside of Chang'an City is paved with green bricks.

It is estimated that if you want to knock out the green bricks and replace them with cement, it will be unpopular. So Qian Rujun is not ready to waste his efforts.

It is estimated that they will not accept it, because cement is not as beautiful as green bricks.

However, blue bricks are not a very easy road for horse-drawn carriages and walkers.

If you want to go far away, Qian Rujun also needs to prepare her bags, at least on the surface, it is stupid not to prepare.

Of course, Qian Rujun had everything to prepare in the space, but he used this excuse to ask the emperor for the right to go out.

"If you want to buy something, make an order for the palace maids, and they will help you buy it, just say what you need, and the palace will help you with the money. If it's something that isn't outside, then you can bear with it, and what you have outside is enough for you to go north. When you go to the north, you will see the scenery and will help you prepare the carriage. It's good for you to sit in the carriage. ”

The emperor returned Qian Rujun's request and said.

Qian Rujun didn't have a good impression of the carriage of this era, especially when he thought of the shock. Without rubber is just inconvenient.

Perhaps knowing Qian Rujun's thoughts, the emperor also added:

"The eldest princess has built a lot of rail transit, and you can travel on most of the sections. I will pass too. Riding a horse for a long time also puts a lot of pressure on me. ”

"This time we marched on the road, because of the rail transit, it can finally be reduced a lot, and the speed can be accelerated, this is also thanks to you, but I heard that Jinmai City, rail transit is more advanced, which is a bit favoritism. Jinmaicheng also invented a new track that could make the speed of chariots and horses faster, and this technology did not seem to make sense for the imperial court. ”

The emperor's words revealed the intention of the empty glove white wolf.

"That's what we spent a lot of money to research, rail transit has not made money, because we have been researching and improving, and want to bring faster and more convenient transportation to the Han, if my father wants to get the research method, then give us this money, so that we can continue to invest in future research." ”

"What is there to worry about with my father. Didn't you give me your father's money?"

Of course, Qian Rujun can't just retreat like this, he must get the benefits!

If the cost of research is not to be paid, then why should we send new research and development methods of rail transit to the imperial court? This will become a common practice. As for giving money, it was given by Qian Rujun as a tax.

Doing business has to be taxed, which is the last word for Qian Rujun.

The idea of rail transit came from what Qian Rujun had seen before, but if the results of hard research could not be given to the imperial court casually, because these things do need to be costed.

Qian Rujun has always told his subordinates that all labor is valuable and must be able to be exchanged for sufficient profits

For inventors, they have always found ways to give incentives, take their inventions in their hands and develop more benefits, or sell them for a better price, and then distribute the money to the inventors.

The Intellectual Property Office, because of this money, can continue to operate, otherwise there is only out, no in, it is not a very good thing for them, as for those inventions are too valuable, the Intellectual Property Office will make up the subsequent money to the inventor.

Now that the Intellectual Property Office has more and more money, most of the time it has been able to give you the bonus at one time, and there is no need to reissue it afterwards.

When it was time to set off, Qian Rujun was surprised by the carriage prepared by Emperor Liu Heng when he got on. This is bigger than the rail caravan that the track used to make.

Running in orbit, it is estimated that it will be difficult.

"There is no way for this car to go on the track, so we need to change trains when we get to the rail station. ”
