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

I have a meeting every morning, and then I review endless official documents.

Fortunately, after using the method of laziness, the efficiency has improved a lot and people have become more relaxed.

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

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

At this time, it was in the suburbs of Luoyang.

Wang Buxing, 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 Minister of Household Affairs, frowned tightly.

I am busy with endless official duties every day, and today I was specially invited to watch such a boring game.

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

"Whether it's durable or not can't be seen at a glance." Wang Buxu smiled slightly.

This was an unknown number of times. After obtaining detailed comparative data, Wang Buxu summoned the ministers.

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

"Zhang Shangshu doesn't know that there are many types of mules. The one over there is huge and about the same size as a horse. That is the mule we are really looking for. It is born from the mating of a male donkey and a female horse.

, its body shape is like a horse, its sound is like a donkey, it looks like a horse but not a donkey. No matter it is a horse or a donkey, it cannot compare with it in terms of endurance, and its pulling power is not bad, and it is also very convenient to raise..."

"And the shorter one was born from the mating of a female donkey and a male horse. This one is basically useless. Whether it is a horse or a donkey, it can't compare..." Zhang Buyi quickly stood up and added.

road.

When he was bored, he took care of this matter himself.

I watched an actual comparison and even took the ride myself.

I asked many questions about the mules carefully.

Of course, the number of mules today is too small, and most of them are regarded as playthings for nobles. The people who raise these playthings obviously do not know these characteristics.

Zhang Cang continued to frown, and his eyes kept glancing at the livestock pulling the plow in the field.

The horse seemed to be struggling a little, and the ox was still pulling, and it was the fastest and plowed the ground the most.

The bigger mules are not very fast, but their strength seems to be very steady, and there is a feeling that you can't tell when they will tire.

The shorter mules are basically lazy and work intermittently.

"How far can this mule travel in one day?" Zhang Cang asked.

He is the Minister of the Ministry of Revenue, and his job is to do the first two calculations.

Whether the mule can be used will be known by asking some key data before performing calculations.

"With nothing to pull, it can travel about a hundred and twenty miles a day. Carrying two stones of grain, it can travel about eighty miles a day. Pulling a cart with ten stones, it can travel fifty miles a day. Two mules can pull a cart together, carrying twenty grains.

A stone can travel more than seventy miles in a day." Zhang Buyi reported a set of data with a familiarity.

During the Qin and Han Dynasties, one mile was approximately equal to 415 meters, one hundred and twenty miles, which was 49,800 meters, equivalent to about 49 kilometers.

Zhang Cang nodded. What Zhang Buyi said were extreme test data.

It is difficult to achieve in actual application.

Even if you don't pull anything, a hundred miles in a day is considered as high as the sky.

But even so, the speed is fast enough.

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

"This thing is easy to raise. It will eat anything, roadside grass, wet or dry grass, but it likes to eat green things, some crop straws, and Shuan. Before, it basically ate whatever it wanted on the road, and gave it one meal a day.

A pound of bean sprouts..."

Hearing this answer, Zhang Cang was stunned.

Regardless of the image, he squatted on the ground and skillfully began to write and draw with his fingers. The calculation method made people feel a headache just by looking at it.

After a long while, Zhang Cang rubbed his eyes fiercely, feeling a little unbelievable.

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

"Zhang Shangshu, please tell me..." Zhang Liang looked at Zhang Cang anxiously.

Although he arranged the matter, he really didn't have that much energy to keep an eye on it every day.

So until now, Zhang Liang doesn't know much more about the situation than others.

"If this statement is true, and with the advance deployment, when the Han Dynasty goes on another expedition, the cost of food, grass and baggage during the journey will probably be more than 50% less than before..." Zhang Cang said with emotion.

This data was so ridiculous that Zhang Cang himself couldn't believe it.

But after his own calculations, he did have such data.

"What?"

"Did Zhang Shangshu make a mistake in his calculation?"

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

As we all know, military expeditions consume a huge amount of energy and financial resources in terms of logistics.

Often, a soldier on an expedition needs at least five corvees to provide logistical support.

Take Jiuyuan County as an example. If the food starts from Luoyang, it will arrive at Jiuyuan County.

If you send out ten shi of food, it would be considered good if you can finally deliver two shi.

People eat horse chews on the way, no matter how frugal they are, they are left here on the road.

Now you say you can save more than 50%?

If ten shi of grain and grass are sent out and five shi are delivered, what will be the result?

In a war involving 100,000 people, they could save at least 200,000 corvees and hundreds of thousands of dan of food.

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

"You may have overlooked one thing Zhang Shangshu mentioned, so prepare in advance!" Wang Buxu smiled, and Zhang Cang had the same idea as him.

Almost everyone knows the upcoming war between the Han Dynasty and Han Dynasty.

They are nothing more than the Huns.

As for sending troops to the Xiongnu, there were only a few routes chosen.

So, isn’t it easy to prepare in advance?

"Counties along the way immediately began to stock up on grain, grass and fodder. The supplies needed for the luggage were all supplied along the way. It took three to five years to stock up on materials. The time is enough. Each place should stock up on its own according to the requirements and save costs. These feeds except for Shu

, everything else is worthless!" Wang Buxian said.

"That's right!" Zhang Cang nodded excitedly.

Sure enough, my thoughts were exactly the same as the king's.

Others are also silently calculating.

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

Although some people were reluctant, there was no way, their wishes could not stop the King of Han from his determination to go to war.

And such a large-scale war cannot be prepared in a short time.

Even the supplies are not all shipped from Luoyang.

According to the usual practice, each county organized the corvee transportation according to the order, followed the prescribed route, and transported it together all the way.

Therefore, in the place where food comes from, it is all scattered. Only when it reaches a certain place will it gather into a large army of baggage.

"Go and prepare, and raise as many children as you can." Wang Buxu directly ordered.

Mules are still very useful, for transportation during wartime and for farm work in leisure time.

The emergence of mules can also make up for the shortage of cattle to the greatest extent.

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

There was nothing to say about this matter, so Wang Buxu gave the order, and then the official in charge handed the detailed records to Zhang Liang.

The above list makes it very clear that depending on the leg strength and needs of each type of livestock, the mule is obviously the most suitable one.

…

The case in Pingyin County is still being handled. Although Wang Buxu handed over the case to Zhang Liang, he also said four words: "Severe, severe!"

Wang Buxu will never be merciful towards this kind of contempt for royal power.

Back in Luoyang, Wang Buxu still called Zhang Liang over.

"It's still a matter of Pingyin County. Let Gu find that there are many problems with the appointment and dismissal of current officials." Wang Buxu said directly.

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