When Yan Fei walked out of the palace, the rising sun in the distance had already risen, sprinkling golden light on Chang'an City, the most glorious city in the world.

After obtaining permission from Li Shimin to go to war last night, twenty young guards selected followed Yan Fei to play with the drone, wanting to learn how to control this clairvoyant technique from him.

Yan Fei didn't care about this, because even if he taught them that there was no replacement of parts, how long could the drone fly? Sooner or later, it would fall from the sky.

It took a night to teach these people how to use solar chargers to charge batteries. There is no need to explain what this is, nor does it have to explain the principles. Just tell them how to turn on the solar panels and how to connect the power supply to observe the traffic lights.

The young guards were all surprised by the magical things and respected Yan Fei very much. The knowledge of this era was not found by searching on the Internet, but was controlled by a small number of people.

It costs a huge amount of money that ordinary people cannot afford to learn knowledge, and not necessarily someone is willing to teach.

This era is the golden age of teachers. In the modern world, the so-called teachers who talk casually in class and make money by opening cram schools outside to make money when they come here, they will definitely be like fish in water, and they can make money from each one.

As for the so-called professors who make people laugh in the public media, if they come here, they will definitely become superior. It is because people in this era are almost willing to give everything to study.

A guard led the way to take Yan Fei to the Right Qianniu Guard to receive his official position. Although the Right Qianniu Guard was just a sesame official from the eighth rank, he was also an official. He needed formal procedures to take office, otherwise he would be arrested and beheaded when he went to the military camp.

"I thought I was such a big official." After getting his own official certificate from the Right Qianniu Guard, Yan Fei was very dissatisfied with the record of joining the army. The mere official rank above the eighth rank was simply to treat himself as Bima Wen.

Fortunately, Yan Fei did not plan to stay in this era for the rest of his life, otherwise he would be pissed to death. Li Shimin was also stingy enough after giving so many good things.

Yang Guang, known as the tyrant ruler of the ages, first opened the imperial examination era. No matter what the imperial examinations have, it did give those people from ordinary people a chance to enter the upper class. This was a feat that was a thousand years ago. At this time, Western countries that claimed to be democratic were still in the dark era of ignorance. The ordinary people in the West were truly inferior to those of cattle and horses.

Whether it was the imperial examination, the Grand Canal, or other reform feats, Yang Guang was infamous, but the Tang Dynasty was fully inherited and created the prosperous Tang Dynasty. The reason why Yang Guang was famous was entirely because he touched the interests of the literati and was thrown into dirty water.

At this time, the imperial examinations were just beginning, and most officials were admitted by those with identities. This is also an important reason why the aristocratic families that were hated by Li Shimin could stand for thousands of years without falling.

Most officials from all over the world have close relationships with them, and many of them are even recommended by them. They can naturally provide help when needed. This is something that the emperor cannot tolerate.

Yan Fei had half a day to arrange family affairs, and then he had to enter the military camp to prepare for the expedition. He first found Zhao Si and returned to the village outside the city with him. He called Cui Er and told them to build the warehouse as soon as possible.

After leaving all the gold nuggets in their travel bags for them as daily expenses and the cost of building a warehouse, Yan Fei found an unmanned place to teleport away from the village.

On the way out of Chang'an City and back to the manor, there were people following him from afar, and Yan Fei needed to go to the towing truck to get things. In order not to expose the location of the towing truck, he had to use teleportation to avoid Li Shimin's eyes and ears.

As for why you don’t drive the trailer directly to the grassland, let alone the shock and trouble that will cause to expose this kind of thing to the Tang people. It is impossible to support the trailer to drive back and forth simply by fuel. In this era, no gas station could refuel Yan Fei’s trailer.

After loading the required supplies into the large backpack from the trailer, Yan Fei locked the car door and pulled some branches to cover the trailer. After doing this, Yan Fei then carried the big backpack back the same way.

------

The carriages, horses, and passers-by bows and arrows were all on their waists. The army was marching and the dust was flying, and the sound of clanging armor and the crisp sound of horse hooves were endless.

Under Li Shimin's will, the entire Tang Dynasty burst out with amazing power in a very short period of time. They spent more than 20 days to build tens of thousands of sets of horseshoes. They also drew a cavalry unit of more than 10,000 from the twelve guards surrounding Chang'an City and secretly headed north to the grassland.

The reason why it took half a month to complete the preparation is not that it wasted time to build horseshoes. After all, this kind of thing that has no technical content can be created on a large scale in a short time.

The main reason is that most of the Tang Dynasty's soldiers were fighting outside before, such as the Xuanjia Army in the distant Meiling. It took a lot of time to gather them from all over the place to Chang'an City.

More than 60% of the Tang Dynasty's troops adopted the system of government troops were concentrated near Chang'an City, while most of the government soldiers in Guanzhong used their respective Zhechong Prefectures and Guards as combat units. This is the first time such as this specializing in the cavalry gathering together.

This team that can be said to have concentrated most of the cavalry of the Tang Dynasty, there is also a Xuan armored cavalry with about 2,000 people. This is Li Shimin's heart. It is the true elite core.

In the past, this Xuanjia Army only accepted the command of Li Shimin, but as the emperor, he naturally could not go out to fight on the grassland again to fight Jie Li. In addition, the cavalry organization drawn from various guards was chaotic, so if he wanted to form combat power, he had to choose a commander with outstanding abilities.

This time, Li Shimin's choice was Li Jing.

Li Jing was not Li Shimin's confidant. When Li Yuan raised an army to rebel against the Sui Dynasty, he even tried to disguise himself as a prisoner and ran to Jiangdu to Yang Admiral. During the Xuanwu Gate Incident, Li Shimin invited him to help, but Li Jing chose neutrality that was not helpful to each other. Even many years later, when Li Shimin pacified the rebellion of Li Chengqian and Hou Junji, he still chose neutrality.

Modern people know that the so-called neutrality is offending both sides. Li Jing stood in the wrong position almost every time he needed to take a team in his political career, but he was able to live well and was entrusted with important tasks. The reason was not because he was Han Qinhu's nephew, but because Li Jing's ability was too outstanding. In history, he destroyed four countries alone, including the powerful Eastern Turks and Tuyuhun.

There is no need to describe Li Jing's great military achievements in history. Just talking about the title given to him by later generations can understand his abilities. In the late Sui and early Tang dynasties, when famous generals emerged, Li Jing won the title of God of War!

It is precisely because of this that at this critical moment of attacking the Eastern Turks, Li Shimin finally chose Li Jing as the main general and sent his private guards Xuanjia cavalry out. This shows Li Shimin's determination and Li Jing's strength.

Yan Fei witnessed Li Jing's military talent with his own eyes. This pure cavalry unit equipped with several horses went north, and marched quickly like lightning whenever the city did not enter. Li Jing integrated these cavalry from different units together, and even when the marching was fast, there was no chaos.

On the official road outside Lanzhou City, passers-by were in a hurry and watched in surprise as a large cavalry team whistling from the south. There was no one in the entire team, only the sound of armor leaves colliding and the rumbling sound of horse hooves trampling on the earth. The blood-red Tang-character flag fluttered in the wind, and when you look around, it seems that you can't see the end at a glance.

"Send the order and set up a camp after thirty miles of Lanzhou." After looking up at the sky, Li Jing issued a new order to the deputy generals beside him. It took them only five days to come from Chang'an City to outside Lanzhou City, and almost no one fell behind. The speed of this marching was no less than Huo Qubing.

After giving the order, Li Jing turned his head and looked at Yan Fei, who was surrounded by twenty right Qianniu Guards not far away. He recalled Li Shimin's explanation before going to war, and decided to set up camp in the evening and had a good talk with this little guy who had Milien eyes. After all, he was about to go deep into the grassland, Milien eyes were a decisive thing and could not tolerate any mistakes.

The reason why Li Jing chose to set off from Chang'an City and ran to Lanzhou City northwest was that Jie Li took more than 200,000 Turkic soldiers and horses to retreat north from the Wei River. Although the Turks had retreated north for almost a month, a large number of troops were still stranded behind. If they chased after Bingzhou, they would probably be discovered, resulting in the failure of the surprise attack.

Although Li Jing was very confident in himself, he was not so arrogant that he thought that he could fight against more than 200,000 Turkic main force with more than 200,000 cavalry in his hands.

So he chose to take a detour from Lanzhou to walk along the Yinshan Mountains from Hetao to Wuyuan County, where Jie Li Jinguan is located. This road can avoid the Turks from detecting their own movements as much as possible.

After setting up camp thirty miles north of Lanzhou City that night, Li Jing sent someone to find Yan Fei.

Yan Fei, who had been riding a horse and following the army for thousands of miles in a few days, was not tired. This kind of rushing march was just a piece of cake for his physical fitness. The only thing that was unhappy was that the twenty guards who were actually responsible for monitoring him followed him all day long, and they were really untiring.

"I've seen the general." Li Jing, who was holding a pen to handle military affairs, had heard that Yan Fei refused to salute the emperor, so he didn't care about Yan Fei's title and the chaos in etiquette. After nodding slightly, he directly asked, "I'll go north after passing Lanzhou and then heading north. How are your clairvoyance prepared?"

"Very good." Yan Fei looked around and ignored the murderous look of Li Jing's personal guard in the tent, and directly looked for Zhang Keshou and sat down. "As long as the general has instructions, it can be used at any time. If the general is worried, he can fly one test tomorrow so that the general knows what he knows."

Yan Fei's words and actions were completely inconsistent with his eighth-rank official. Li Jing's personal guards in the big tent had already held their hands on the hilt of the knife. The army was hierarchical and the military law was strict. Yan Fei's words and actions were enough to cut his head several times.

Li Jing, who had a red face, did not call on the soldiers to push Yan Fei out to chop his head or beat military sticks, but nodded and suddenly asked, "You are here with the army, what's wrong with it along the way?"

"There is no problem with riding a horse." Yan Fei laughed and said, "It's just that the food is not good. I can't eat hard cooked cakes. If possible, I hope I can improve the food."
