Li Er's words made Li forget his worries and was speechless.

He totally ignored such a simple truth. The brain drilled into the tip of an ox's horn, and has been thinking about how to make a four-wheel carriage drive in the desert.

Not only him, but also Cheng Yaojin and others did not expect such a simple method.

Since there are no carriages in the desert, it is necessary to use camel teams to transfer materials. The Tengger desert is only more than 200 miles wide. Camel caravans do not travel in a straight line, but need to fluctuate along sand dunes and constantly detour around oases.

But even so, when everything goes well, the camel team will pass through the desert for up to half a month, which will not delay the army for too long.

The main components of the four-wheel freight wagon are just wheels, axles, beams and steering mechanisms, which can be disassembled and transported across the desert by camel teams.

After passing through the desert, the craftsmen in the army will cut down trees and make a new four-wheel carriage again. It doesn't take much trouble.

In this way, the logistics of the western expedition army can be easily guaranteed.

After the military grain is made, it is transported to Dunhuang County by four-wheel carriage and can be reached in ten days. Then it will be transported by the camel team to the other side of the desert, and then taken over by the four-wheel carriage.

As soon as possible, a batch of baggage and materials can be transported from Chang'an city to the western countries in about 30 days. Even if the road encounters extreme weather such as rainstorm and sandstorm, the slowest is only two months.

Even Li forgot to worry about how much benefit this transportation line could bring to the Tang Dynasty after the army conquered the western regions and established the anxidu protectorate.

The goods of those caravans traveling to and from the silk road can be transported in this way, and the transportation cost and time will be greatly reduced. Datang can also get countless benefits from it.

Even if the economic benefits are eliminated, the connection between the western regions and the Central Plains will be closer after this traffic line is opened.

In history, Li Er established the Anxi capital protectorate in the 14th year of Zhenguan, brought the western regions into the central rule, stationed farmland, collected taxes and troops, and swore the sovereignty of the Tang Dynasty.

But that's all. The Tang Dynasty ruled the western regions for only a hundred years. It was not until the Qing Dynasty that the western regions were brought into the Chinese territory again.

The fundamental reason is that the connection between the western regions and the central government is too far away to maintain rule.

Once the western expedition army opened this traffic line, the western regions could be integrated with the Central Plains. The Tang Dynasty's rule over the western regions will no longer disappear after a flash in the pan.

Li forgets sorrow to have to admit that Li Er's brain hole can be called a genius.

Cheng Yaojin, Yuchi Jingde and other national leaders also flattered Li Er's genius idea for a while.

After Li forgot to worry about these things, he clapped his hands: "my uncle is really great and talented, and my nephew admires him more than anything. I'll order someone to send a message and let the work department and the general make preparations as soon as possible."

Li Er snorted proudly: "no, I've already ordered the work department and the general to be the supervisor and made the accessories of thousands of carriages. I've ordered people to leave in advance and send them to Dunhuang county."

Li forgot to worry. It turned out that Li Er had already come up with a solution, but out of bad taste, he deliberately saw himself uncomfortable.

However, even though he was teased by Li Er, Li Er did not deceive him. In this way, it was very easy for him to go back and forth to Chang'an after conquering Gaochang country in eight months.

Li forgot to worry and quickly bowed to Li erchang: "thank you, uncle. I'm very grateful. My nephew was so wayward before. Please don't remember me. Forgive me."

"Well, it's true to concentrate on your work in the future. Don't be petty! You also want to be a father and a county magistrate, and you can't fool around like this. If I don't force you to go to the western regions, I'm afraid I won't take it out until when you bastard."

"Yes, yes, my uncle taught me a lesson." Li Er solved a big problem for him. Now no matter what Li Er taught me, Li forgets to worry only has the right to listen.

Li Er is very proud to teach Li to forget his worries, which is regarded as letting him go.

Li forgot to worry about it, and with a group of national leaders, he kept flattering Li Er's rainbow, coaxing the eternal emperor to laugh and drink a glass of beer like water.

After Li Er and the princes were carefully guarded by the guards and returned to Chang'an City, Li forgetful also breathed a sigh

A few days later, it was finally the day of departure.

With the help of Aphrodite and Perrin, Li forgot to worry and put on the shining silver armor.

At the moment of departure, he tightly hugged Su Changqing, who had already cried into tears, gently stroked her hair, and whispered in Su Changqing's ear, "Changqing, wait for me at home!"

Su Changqing rubbed with tearful eyes, but grabbed Li forgetful's clothes and nodded desperately.

In fact, if it were usual, they would not be so sad as to "live and die".

It just happened that Su Changqing was pregnant, but the strong women who used to be strong turned into tender water.

Finally, he calmed the beauty's boss and repeatedly ordered the old housekeeper Li Heng and Peilan to take good care of him. Li forgot his worries and reluctantly stepped on the Royal horse saluzi given to him by Li Er.

Holding back his heart, Li forgets worry and doesn't dare to look back. He directly urges his horse to gallop towards the door of the house.

Niu Wu immediately led a group of Li Fu's trilogy, followed by urging Ma to follow closely.

Peilan and all the maidservants in the house bowed down: "I hope you can plow the court and sweep away the hole and return in triumph!"

Niu Yong was not suitable to accompany Li forget you on the expedition because of his disabled arm, so he still stayed in the house and led the rest of the episodes to guard the Li family's courtyard.

At this moment, he talked about one arm and sounded a war drum, making a magnificent drum sound for his husband.

Outside Li's house, a group of farmers in Dingzhou village have already gathered on both sides of the village road under the leadership of the old village leader.

Seeing Li forgetful and leading the crowd to appear, all of them bowed down.

"I hope you will come back in triumph!"

"Plow the court and sweep away the hole, return in triumph!"

Li forgets to worry only feels that his nose is sour, but he doesn't dare to stay any longer. He can only salute the farmers and urge them to leave

Instead of going directly to Jingzhou, he had to go to Chang'an first.

All the officers and men of the Tang Dynasty will hold ceremonies outside Chengtian gate in the imperial city.

When Li Qieyou led the episode to Chang'an City, a group of dandies were waiting outside Mingde gate in military uniform.

Seeing Li forget you appear, even if there are no formal dandies in normal days, they all knelt down on one knee to Li forget you, then punched their chest armor with right boxing, and gave Li forget you a military salute in good order.

From today on, the people are Li's subordinates. The ceremony can't be abolished.

After the ceremony, the dandies turned over and got on their horses. Surrounded by Li forgetful, they drove their horses to the rosefinch Avenue and went to the rosefinch door.

On both sides of chengtianmen street in the Imperial City, there are strong forbidden troops with bright armor and banners.

The two thousand or so Yi Wei Xiao riders were all ordered by Li Er to protect Li forgetful and follow him to the western regions.

After three shots, the Chengtian gate opened. Li Er, who was also dressed in military uniform, rode out of the palace gate.

Li Qieyou immediately turned over and dismounted, led the dandies and a group of soldiers, three kowtows and nine kneels to salute.

The army set out to fight with strict etiquette.

Worship heaven, earth, temple, military God
