After determining the safety of the route, Long Hao traveled back and forth between the two places many times and sent a large number of skilled workers to the station outside Yanmen Pass.

At the same time, he also selected some members from the Huaxia Self-Defense Force with strong learning ability, and trained several pilots to take over his future work.

Of course, the learning process for these members can only be gradual, starting with private jets with less than 10 passengers, and gradually gaining flying experience.

When they are proficient in the operation of relatively simple private jets, they can learn about regional airliners with more seats and higher requirements.

According to the relevant parameters of the airport construction plan of the Tuvalu Special District, a modern airport that can take off and land large civil aircraft has also begun to be planned between Huaxia City and Yichang New Town.

All ancillary facilities at the airport, as well as the training of airport managers, are carried out in parallel with Tuvalu Airport in order to maximize resource sharing.

Although these official members of the Huaxia Kingdom cannot be compared with the people in the real world in terms of the breadth of knowledge.

However, due to the existence of the time gap between the two worlds, with several times the learning time, a more adequate level playing field and abundant learning resources, these aspiring formal members can obtain a more solid professional knowledge base.

The prosperity of the aviation industry cannot be achieved in one or two years without the support of too many basic scientific and technical personnel.

But in any case, Huaxia Kingdom has now decided to get started.

Although the steps they take are small, as long as they follow the right direction and move forward step by step, they will one day be able to keep up with the pace of the real world.

After Long Hao transported enough skilled workers from Huaxia Kingdom, the Yanmen Pass station was also lively.

According to the high-definition digital map that Li Yan and his colleagues brought back, the Ministry of State-owned Assets Supervision and Administration of Huaxia determined where the future resource-based city would be built, as well as the location of each urban unit when it was expanded in the future.

This new city was named Ping'an City by the people of the Ministry of State-owned Assets.

After having these materials, the construction of Ping'an City was officially started outside Yanmen Pass.

Skilled workers who can operate specialized machinery must be dispatched from Huaxia, which is a matter of no choice.

Because except for Huaxia, there is simply no labor force in other places that can skillfully operate these modern machinery.

But in the same way, for those ordinary jobs that only need a lot of effort, the requirements for the labor force to have cultural knowledge are not high, and there is no need to dispatch from Huaxia.

Because at present, the main use of air transport between the two places is to transfer personnel, and the cost of such personnel transfer is not a small amount.

In order to make up for the lack of ordinary labor, Li Yan decided to recruit some civilians from Yanmen Pass and Datong to deal with some details that were difficult to handle with machinery.

Anyway, the guards of Yanmen Pass had to pass through the guards of Yanmen Pass to transmit back to Wei the location that Huaxia had arrived, and send the interpreter they had confirmed.

Therefore, Li Yan took two self-defense members and drove an off-road vehicle along the winding official road to Yanmen Pass.

The siege of Yanmen Pass was built along the mountain, with a circumference of more than five kilometers. The southern end of the wall is connected to the east and west wings of the castle, and to the north it extends along the ridge to the valley floor, where a gate is built.

Outside the siege, there are also three large stone walls and twenty-five small stone walls, which act as barriers.

Between Yanmen Pass and Guancheng, the Great Wall is connected with stone, and every 120 meters or so, a beacon tower and an enemy tower are built.

In the dangerous area, forts, moats and secret doors were also set up, forming a complete set of defense system.

Such a complex defense system is indeed a rare fortress in the world for people in the era of cold weapons.

But for Li Yan and others, who already had the ability to fly above the sky, the steepness of this Yanmen Pass did not give them much obvious feeling.

Because no matter how steep the mountain is, in the eyes of heaven, there is no obstacle that cannot be overcome.

After such a long period of time, Li Yan believed that Sima Yi of the Wei State should have spread the news of their arrival in northern Xinjiang to the guards at the border pass.

Therefore, he directly asked people to plant a flag of Huaxia Kingdom in the middle of the official road outside Yanmen Pass, and then the three of them sat on the off-road vehicle and waited for the response of the soldiers who closed it.

The world map on the banner was unfurled in the wind, conveying the information that they had arrived to the guards at the border gates.

In fact, everything Li Yan did outside Yanmen Pass did not escape the attention of the scouts at Yanmen Pass.

Because Li Yan and they didn't have any concealment about their behavior at all.

In addition, the frequent take-off and landing of planes had to fly through the Yanmen Gate, so it was almost impossible to hide from the eyes and ears of Wei to make such a big move.

Li Yan The interpreter they needed was a very simple matter for these soldiers of the Northern Frontier who often dealt with the Xianbei people.

Soon, a small crack opened in the gate of Yanmen Pass, and several Wei people with the national emblem of Huaxia were pinned to each of them led a horse out of the pass.

One of them was Sima Yi's people, who was responsible for handing over these interpreters to Li Yan and others, and returned to Yanmen Pass after completing the mission.

Li Yan looked at the remaining five Wei people, wearing tattered cotton jackets, and those fist-sized holes in the cotton jackets could not block the cold wind in the northern Xinjiang at all.

Only half of the trouser leg remained, and one side was blown by the cold wind to stick to the calf, and the other side kept shaking like a flag, I don't know if the leg was shaking or the wind was moving.

Li Yan sighed, took out a few sets of warm clothes and pants, and asked them to put them on.

In such a cold weather, if you only wear this, you have to go out of the customs to do such dangerous things, no wonder a few people look miserable.

The fleece clothes and pants quickly made these people's faces a little bloody, at least, as soon as they saw that they didn't do anything, they could be issued a set of thick clothes and pants, which was definitely not for them to die.

Li Yan said: "Since you have been sent by the King of Wei to assist us in the work of the Huaxia Kingdom, you have to do everything according to our requirements.

With the badge you wear, at least while you are doing things for us, your lives will be protected by our Huaxia Kingdom.

As long as you do your best, Huaxia Guobao will ensure that you have no worries about food and clothing.

It's windy here, it's not easy to talk, and for more things, let's go back to our station first. ”

The off-road vehicle turned its head on the flat ground outside Yanmen Pass in the wind, raised a cloud of sand, and went directly back to the station.

As for whether these Wei people could keep up, they didn't think about it at all.

Because in Li Yan's opinion, these people simply got a great opportunity out of thin air.

As long as you do your best in this work, it is a sure thing to obtain the status of a member of the periphery of the Chinese country.
