It is always easier to destroy than to build, the ancients spent countless lives and wealth to build Xiongguan, with the efforts of more than a dozen excavators, it did not take long to become a pile of ruins.

Originally, Li Yan also thought about processing those wood into tables and chairs or other furniture, but after receiving the samples, the people from the Ministry of State-owned Assets and Assets Supervision and Administration looked at them with professionals and thought that they had no value.

After all, due to the limitation of tools, the materials used to repair these houses cannot be large, and the processing is not as good as those large materials that are cut by themselves.

For the south, which has a lot of forest resources, these ordinary timbers in the north can only be regarded as rotten wood.

As a result, the wood that was considered waste was returned to the Heian Castle site and used as fuel for power generation.

In the absence of thermal power stations, the use of biomass power generation is still a simple and efficient way to supply electricity.

A lot of dead grass is the best source of fuel, but in comparison, the wood removed from the house has a much higher burn value than dead grass.

Although there is a large open-pit coal yard in the mountains not far from Heian Castle, it will not be able to become the main energy source of Heian Castle until it is developed.

Li Yan, who was already accustomed to smoothing the cement pavement, felt uncomfortable when he saw the rugged ancient road, so he directly arranged it and prepared to repair the entire ancient road.

There is no need to spend so much effort, just on the original roadbed, dig what should be dug and fill in what should be filled.

By the way, it doesn't take much time to clean up the weeds on the side of the road and widen the places where there are potential safety hazards.

This Yanmen Ancient Road is one of the most important passages connecting the north and south for the circulation of materials in the nearby area of hundreds of kilometers.

Like in the past, many sections of the road could only accommodate one horse-drawn carriage at most, and the roads were potholed and very difficult to walk.

But the tens of kilometers of ancient roads, after the excavators have been vigorously repaired, the roadbed has been widened to accommodate at least two horse-drawn carriages side by side.

This also means that some small agricultural locomotives in Huaxia can also run on this ancient road unimpeded, creating conditions for the large circulation of materials and people in Ping'an City and Guannai.

The Great Wall on both sides of Yanmen Pass was also sealed, and Wei was informed that garrisons from other places could not operate within a radius of 200 miles from Ping'an City without the permission of Huaxia.

Of course, you have to give a sweet date after a slap.

In addition to being responsible for the security within a radius of 200 miles, Ping'an City also promised to protect the checkpoints on both sides of Yanmen Pass that could not be quickly supported due to the disconnection of the Great Wall, and to prevent those Xianbei people from entering the pass through other checkpoints to plunder the people of Wei.

There is Huaxia, a country that does not know the depth of force, to build a city here, and most of the land occupied is barren mountains and the territory of the original Xianbei people, the king of Wei thinks it is good, at least Huaxia has not taken the initiative to provoke wars in neighboring countries for no reason, in comparison, this neighbor is much better than the Xianbei people.

However, some far-sighted people in the DPRK and China have already felt that something is wrong, and it is not the first time that Huaxia has built a city on the border of another country like this.

The first time was in the deep mountains near Yunmengze, but it only took three years to develop from a little-known Huaxia Mountain Villa to a country with a population that could rival the Three Kingdoms.

There are not many cities in this country, even with Zigui City and the Huaxia Villa built in the mountains, there are only seven cities, and three of these seven cities are still under construction.

Judging from the number of cities and the scope of its jurisdiction, there is nothing unusual about this Huaxia Kingdom.

However, the magical steel city built in the middle of Yunmengze, Huaxia City, absorbed nearly one million people from the surrounding area in one city.

A city that does not occupy a very large area, but has such a terrifying capacity to accommodate the population, is definitely a shadow that the surrounding countries will never be able to wipe out.

In addition, some of the policies implemented by the Huaxia Kingdom are simply incredible.

As long as you can pass their assessment, you can become a full member of the Huaxia Kingdom, so that you will have almost no worries about food and clothing for the rest of your life.

Even those people who are attached to the Huaxia Kingdom to do things, as long as they are diligent in their work, they can at least ensure that the family has no worries about food and clothing.

They also know how attractive such a policy will be to those at the bottom who live on the brink of life and death, but such a policy is not something that other countries can emulate.

If Wei followed that policy, it would probably not take a year to drain the treasury, which seemed to be quite abundant on the surface.

Therefore, such a move by the Huaxia Kingdom is an upright conspiracy to "grab" the population from the surrounding countries openly, but these countries have no way to take him.

This time, what kind of miracle will Huaxia create when it builds a city in this desolate and water-scarce northern frontier, which is unknown to all Wei people.

But there is one thing they know that this so-called Ping'an City will definitely suck away a large number of ordinary people from Wei and Xianbei, which is something that no one can change.

It's just that Huaxia City in Yunmengze accepts Han people of the same clan, living habits and written language, while Ping'an City chooses between Han people and other races, and wants to rub two ethnic groups with different bloodlines and living habits together, which cannot be said to be a great challenge.

How to deal with the problem of peaceful coexistence between the Xianbei and Han people is something that the high-ranking Wei leaders will never be able to figure out.

Based on their knowledge, the method pursued for thousands of years is to use razing to defeat raze, and use all kinds of conspiracies to stir up contradictions between foreign races, so that they can conflict with each other, in the hope that they will get a temporary recuperation.

This kind of practice, to put it bluntly, is that they are not strong and confident, because they are afraid, afraid that the integration of foreign races will mess up the bloodline, and they are afraid that they will make too many enemies and be pulled down by others.

The so-called balance is nothing more than supporting the weak against the strong, allowing them to weaken each other in order to gain absolute control.

A strong enemy needs a strong force to contend with, but too strong a force is not easy to control, so it can only be fought small and early, and they cannot be fused.

In this way, the country will not need to maintain such a strong force that is difficult to control, so as not to jeopardize its own dominance.

Therefore, the power of the emperor almost directly determines the strength of a country.

Only when the emperor can easily control the power of a country, twist these forces into a rope, and adopt the strategy of long-distance friendship and close attack, can it be possible to expand the territory.

This is due to the limited abilities of individuals, because few are fools relative to the leadership of any of the forces.

No one will be much smarter than anyone until information has accumulated to a terrifying level and a new way of thinking has been created through full sharing.

In this sense, bamboo slips, the carrier of information accumulation and dissemination, are destined to play so many roles.

The arrival of the Huaxia Kingdom not only made the Yanmen Ancient Road in reality wider, but also made another "ancient road" that lasted for thousands of years wider, wide enough to cover the entire world.
