After returning to Luoyang, Wang's life became regular again.

I have a meeting every morning, and then I review the official documents that I can't read.

Fortunately, after having lazy means, the efficiency has improved a lot, and people have become a lot easier.

External events are gradually calming down, and the country is gradually becoming more stable.

Next month, the generals who have been fighting abroad should also return with their armies in triumph.

And at this time in the suburbs of Luoyang.

Wang, who had deliberately finished his official duties earlier, was watching a game with a group of ministers.

"Your Majesty, this thing doesn't look as durable as it says......" Zhang Cang, the head of the household, frowned tightly.

I am busy with official business every day, and I was specially pulled to watch such a boring game today.

Not only Zhang Cang was a little reluctant, but other ministers were also reluctant, which was a waste of time.

"It's not easy to see if it's durable." Wang Buyu smiled slightly.

This is the first time I don't know how many times, and after having detailed comparison data in front of me, Wang Buxing summoned the ministers over.

After everyone has seen it, the next step is to focus on promotion.

"Zhang Shangshu doesn't know, this mule is also divided into many kinds, the one over there is huge, not much different from the horse, is the mule we are really looking for, he is born from the mating of a male donkey and a female horse, the body shape is like a horse, the sound is like a donkey, like a horse is not a donkey, whether it is a horse or a donkey, it is not comparable to it in terms of endurance, and its pulling strength is not bad, and it is also very convenient to raise......"

"And the lower one is born from the mating of a female donkey and a male horse, which is basically useless, whether it is a horse or a donkey, it is not as good as ......" Zhang Buyi hurriedly stood up and added.

It's boring, but he did it himself.

I watched an actual comparison and took a ride with me.

I asked a lot of questions about the mule.

Of course, the number of mules is too small nowadays, and most of them are regarded as the playthings of the nobility, and the people who keep these playthings are obviously not aware of these characteristics.

Zhang Cang continued to frown, his eyes constantly glancing at the few livestock that were pulling the plough in the field.

Ma Xian was a little struggling, and the cow was still pulling and pulling, and the speed was also the fastest, and the ground was also the most.

The larger mules were not fast, but their strength seemed to be very steady, and there was a feeling that one could not tell when they were going to get tired.

The mules, on the other hand, are basically lazy and work intermittently.

"How far can this mule go on a day?" Zhang Cang asked.

He is the head of the household, and he is engaged in the work of the first two calculations.

Whether a mule can be used or not, just ask some key data to do the calculation.

"If you don't pull anything on your body, you can travel about 120 miles a day, carry two stones of grain, you can travel up and down 80 miles a day, pull a cart of 10 stones, you can travel 50 miles a day, and two mules can pull a cart together, carry 20 stones of grain, and you can travel more than 70 miles a day." Zhang Buyi is familiar with a set of data.

During the Qin and Han dynasties, one li was equal to about 415 meters, one hundred and twenty li, that is, 49,800 meters, equivalent to about 49 kilometers.

Zhang Cang nodded, what Zhang Buyi said was the limit test data.

It is very difficult to achieve in practice.

Even if you don't pull anything, a hundred miles a day will be considered the top of the sky.

But even so, it's fast enough.

"What is the feed you need?" How much do I need to eat per day? Zhang Cang continued to ask.

"This thing is easy to raise, it can eat everything, the grass on the side of the road, wet and dry, but it likes to eat green, some crop straw, and soybeans. Before, I basically walked and ate on the road, and I was given a pound of soybean ...... a day."

Listening to this answer, Zhang Cang was stunned.

Squatting on the ground regardless of the image, he skillfully began to write and draw with his fingers, and the calculation method made people feel a headache at a glance.

After a long while, Zhang Cang rubbed his eyes violently, feeling a little incredulous.

"Your Majesty, if this is true, then this thing ......" Zhang Cang looked at Wang Buxing and the others in surprise.

"Zhang Shangshu said quickly......" Zhang Liang looked at Zhang Cang with some anxiety.

Although he arranged the matter, he really didn't have that much energy to stare at it every day.

So now, Zhang Liang doesn't know much more than others.

"If this statement is true, coupled with the advance deployment, when the Han Dynasty goes on an expedition again, the cost of grain and grass on the way will be more than 50% saved, I am afraid it will be more than 50% less than before......," Zhang Cang said with emotion.

This data is so blind that Zhang Cang himself can't believe it.

But after his own calculations, he is indeed such a data.

"What?"

"Zhang Shangshu miscalculated, right?"

"Even if you save something, you shouldn't save so much, right?"

It is a well-known fact that the energy and financial resources expended on the logistics of an army expedition are enormous.

Often, an expedition to a soldier requires at least five conscripts to be responsible for the logistics of the expedition.

Take Jiuyuan County as an example, if the grain starts from Luoyang and goes to Jiuyuan County.

Ten stones of grain were sent out, and it was good to be able to deliver two stones in the end.

On the way, people eat horses and chew, no matter how economical they are, but the road is placed here.

Now you say you can save more than 50%?

If ten stones of grain and grass are sent out, and five stones can be transported, what will be the result?

In a war of 100,000 people, they can save at least 200,000 conscripts and hundreds of thousands of stone of food.

"It can't be wrong, absolutely not!" Zhang Cang shook his head violently, he was extremely sure of his answer.

"You may have overlooked one thing that Zhang Shangshu mentioned, prepare in advance!" Wang Buxing smiled, and Zhang Cang thought of it with him.

The next war of the Han Dynasty is clear to almost everyone.

It is nothing more than the Huns.

And to send troops to the Huns, there are only a few routes chosen.

In this way, it is not easy to prepare in advance?

"Along the way, the counties immediately began to hoard grain, grass and forage, the weight is needed, are supplied along the way, with three or five years to hoard materials, the time is enough, all over the country according to the requirements of their own hoarding, and can save costs, these feeds are worthless except for mushrooms!" Wang Bu said without hunger.

"Exactly!" Zhang Cang nodded excitedly.

Sure enough, his own thinking was exactly the same as that of the king.

Others were also silently pondering.

War with the Xiongnu is certain, and now the imperial court is already making preparations.

Although some people were reluctant, there was no way, their willingness could not stop the Han king's determination to go to war.

And such a large-scale war is not something that can be prepared for a while.

Even if it is a material, not all of them are shipped from Luoyang.

According to the usual practice, it is the counties that organize the transportation of conscripts according to the order, take the prescribed route, and converge all the way to transport it together.

Therefore, in the place where the grain is sent, it is all scattered, and only when it reaches a certain place will it gather into a heavy army.

"Go and prepare, and raise as much as you can." Wang Bu was not hungry and ordered directly.

Mules are still very useful, transported in wartime, and used for farm work in leisure time.

The appearance of mules can also make up for the lack of cattle to the greatest extent.

In other words, it's an effective way to boost productivity.

There was nothing to say about this, Wang Buxing ordered, and then the official in charge handed the detailed record to Zhang Liang.

It is clear from the above list that the mule is clearly the most suitable one for each type of animal.

……

The case in Pingyin County is still being handled, although Wang Buxing handed over the case to Zhang Liang to be responsible, but he also explained four words, strict and serious!

For this kind of contempt for royal power, the king will never be merciful.

Back in Luoyang, Wang was not hungry but still called Zhang Liang over.

"It's still a matter of Pingyin County, so that Gu found that there are many problems with the appointment and dismissal of current officials." Wang Bu was not hungry and said directly.

He had considered this question a long time ago, but he had never made up his mind.

After the incident in Pingyin County was exposed, Wang Buxing had to seriously consider this matter again.

As a result, this decision was finally made, and there must be hidden dangers and worries, but if this is not done, the local forces will be intertwined, which is not conducive to the centralization of power.

"Then what is the king going to do?" Zhang Liang asked with a serious face.

At first, he would think about it seriously and then say some of his own opinions.

This habit has since changed.

No matter how much you think about it, Wang Bu is hungry and says so, which proves that he has a solution.

Instead of bothering on what to do, it is better to listen directly to Wang Buxing's explanation of the solution, and then spend your brain thinking about whether it is appropriate.

As a high-ranking official of a country, he not only needs to be proficient in time management, but also needs to teach himself brain management, otherwise he will really use his brain too much one day.

"Officials are appointed and dismissed from other places!" Wang Bu was hungry and said directly.

"Appointment and dismissal in a different place?" Zhang Liang frowned slightly.

Strictly speaking, non-local appointments and dismissals also exist, but most of them are county-level officials, and there are also county-level officials, but more than seventy percent of them are locally appointed and dismissed.

But soon Zhang Liang figured out the benefits of doing so.

"Non-local appointment and dismissal, with the tenure system, the matter of officials colluding with the party and private interests should not be so serious, but the problem is not without problems, one is the resistance to the implementation of this matter, local forces are intertwined, and the new officials are not familiar with the situation, can they be suppressed? Second, these officials appointed and dismissed in other places, because they have a term of office, will they do something that only cares about the present? Zhang Liang said.

"There will definitely be resistance, but if you care about these resistances and don't do it, I'm afraid that you will encounter worse things than Pingyin County in the future, as for whether you will do something that only cares about the present, this requires the Ministry of Officials to do a set of evaluation methods, I think that in addition to the evaluation of the Ministry of Officials, let the scout also give an official tablet evaluation, the Ministry of Officials test ability, Scout test morality, one bright and one dark, who can rise, who can't rise, there may be some ......numbers in my heart."
