"Ziyou, I've tasted all the military rations you ordered people to get. If it can be preserved for a long time, as you said, my fighting power of the Tang iron cavalry can be improved by three points! I've written down all these merits for you. I'll give them to you when the western expedition army returns in triumph!"

Li Er's words are not exaggerated at all.

Whether soldiers can eat well will also affect their combat effectiveness.

There are many examples in history of winning wars because of improving food.

Li Er is not unwilling to provide better military food for the army. It is just that problems such as limited transportation capacity and how to cook on the battlefield have not been improved.

In fact, since Li Qieyou accidentally discovered potato, a high-yield crop, and popularized it to the whole country of the Tang Dynasty, food and were no longer the main reasons restricting the logistics of the Tang army.

Transportation, storage and how to cook are the key.

These methods of making military grain made by Li forgetful worry perfectly solved the logistics problem of the army.

For example, with corn, potatoes and steamed rice mixed with bacon, it can be easily preserved for about a month by sealing it in a pottery pot and vacuuming it.

Lunch meat is just to stir the pork into meat paste, add seasoning and starch, and steam it in a pot. It is very convenient to eat when it is stored in vacuum.

Moreover, Li Er and all the country leaders, after tasting the taste of lunch meat, were full of praise and thought it was a rare delicacy.

It was a great surprise to the emperor and officials of the Tang Dynasty that military grain could be made so delicious and stored for a long time.

As for instant noodles, it's even simpler.

Roll out the noodles, steam them in a pot, and then fry them in an oil pan until they are very thorough.

Although Li forgets worry and can't find seasoning bags of various flavors of instant noodles in future generations, even boiled noodles with clean water makes Li Er and all the leaders of the state enjoy it.

After tasting these military rations for the first time, Li Er and the princes couldn't believe that they were so delicious that they were supplied to the army.

More importantly, the cost of making these military rations is not high.

Li Er even ordered officials of the civil affairs department to calculate that because the new military grain is easier to transport and store, if the transportation loss of millet and livestock is included, after the army changes the new military grain, the wasted grain is even less than the original millet.

Eating better and spending less money, Li Er naturally Longxin was so happy that he immediately came to Dingzhou village and praised Li forgetting his worries.

Li forgets to worry, but his heart deflates secretly. In his opinion, it's better to let him go home to accompany his daughter-in-law.

Of course, he also knows that this is nothing. Now Li Er will certainly not let him go. Therefore, Li forgets to worry about Li Er's words, but only smiles and doesn't say anything.

Li Er picked up his beer glass and drank it happily. Then he glanced at Li forgetful: "Ziyou, are you complaining about me?"

"I dare not."

"Hum, I know if you don't tell me. You bastard, you're not promising at all. You're around a woman every day!" Li Er angrily glared at Li forgetful and continued: "in fact, I didn't deceive you. It's not difficult for the army to arrive in Gaochang country in three or four months."

Li Er was stunned by this. Then he was overjoyed and asked, "uncle, don't deceive my nephew. My nephew asked me, it's more than 2000 miles from Dunhuang county to Gaochang country. It takes at least two or three months for the army to transport luggage by camel team."

"Hehe, Ziyou, you are really stupid! I ask you, can't you use a four-wheel carriage to transport? It can be 200 miles a day, but in more than ten days, the army can run two thousand miles. Why is it difficult?"

Li forgot to worry and replied, "but... But the four-wheel carriage can't pass through the desert."

Li Er smiled more and more happily, but he deliberately didn't answer, which aroused Li's appetite to forget his worries.

Now Li forgot to worry and was silly. All the leaders of the state, including Cheng Yaojin, were also silly. They didn't understand what was in Li Er's words.

Yuchi Jingde and others thought Cheng Yaojin was right.

From Jingzhou to Dunhuang County, the army can rely on four-wheel carriages to transport supplies, but later, it can only be replaced by camel teams, which is absolutely right.

Why does Li Er still swear so firmly that Li forgets his worries and continues to use four-wheel carriages to transport baggage?

Li forget worry is more anxious, repeatedly give Li Er a bow: "uncle, my nephew is wrong, my nephew is stupid, please give me some advice!"

He really couldn't think of a way to get the carriage through the desert.

He even made a special trip to Xishi to find several Hu merchants who had been on the Silk Road for a long time and asked them how to solve it.

After some inquiry, Li forgot to worry about the idea of transporting baggage by carriage.

Because he thought too simple before.

In later generations, when Li forgot to worry about traveling in the desert, he once made a desert car and surfed on the sand dunes, which was very exciting.

So he thought that as long as he made rubber tires or other alternatives, he could make the carriage pass through the Tengger Desert.

But this is not the case.

When crossing the desert, the camel team does not walk in a straight line, but must move forward meandering along the ridges of various sand dunes.

First of all, it is for safety.

The climate in the desert is changeable, and sandstorms may occur at any time. Once a sandstorm is found, the team must kneel the camels on the windward side of the sandstorm.

If you walk at the bottom of the sand dune, if you are not careful, you will be buried by the sand dune.

In this way, even with rubber tires, the carriage can not be used.

Camels can't pull carriages and walk on the top of sand dunes. That's unrealistic.

It was after making this clear that Li forgot his worries and completely died.

At the moment, Li Er said he had a way, which naturally made Li forget his worries and be surprised and happy.

Li Er was very satisfied with Li's worry free attitude, even a little proud.

His nephew gave him too many surprises. He was so clever that he often made Li Er doubt his IQ.

Now he can finally overcome Li's worries. Needless to say, Li Er's pride in his heart.

He coughed and said slowly, "Ziyou, I'll ask you, can that four-wheel carriage be made easily?"

Li forgot to worry again and seemed to think of something.

"Uncle Hui, in addition to the wheels and beams of the carriage and the steering mechanism, other parts are not difficult."

The skilled craftsman of Datang also makes Li forget his worries and marvel.

Today's four wheeled carriage is no longer the kind of crude carriage built by Carpenter Liu to cope with the task of transporting grain in spring.

At present, the girder and steering mechanism of the carriage are made of metal after many tests by the Ministry of work and the craftsmen who will be the supervisor.

The resulting change is that the four-wheel carriage has a higher load and the steering is more convenient and smooth.

As for the other parts of the carriage, the ordinary carriage for pulling goods is simple. It is basically made of wood.

Li Er laughed at the speech: "in that case, Ziyou, why can't you disassemble those carriages in Dunhuang county and reassemble them when the army passes through the desert?"

Li Er's words made Li forget his worries, and the whole person was petrified.

Ma Dan, why didn't he think of such a simple truth before
