Chen Ziyang used his spare time before going to work after graduating from college to inquire about the secrets of the Dragonfall Land. First, it was because he missed the old way, and secondly, he felt that this dragonfall land also had a deep relationship with him.

Chen Ziyang didn't understand why such a large place as his hometown could become the place where Pu Yi announced his abdication. For this reason, he first went to the site of Puyi's abdication. Pu Yi's abdication site, the entrance fee is only three yuan, this is probably the cheapest tourist attraction in China, Chen Ziyang thought when he came here.

This site is just a yard of one or two hundred square meters, a few houses, this house was originally the staff canteen of the Great Walnut Mine Co., Ltd., and now it is relatively well preserved, and it has been rebuilt into the old site today, where Pu Yi announced his abdication. There are only a few photos of the time hanging in the old site, and there is nothing meaningful.

After that, Chen Ziyang went to the city library to check the county records, and only then did he know the reason. Mineral! It's because of the minerals here.

Chen Zi Yang Kee's big walnut town was very inconvenient more than ten years ago. Da Walnut Town is located in the mountainous area of Changbai Mountain, and if you want to go to Linhai City from Da Walnut Town, you must either take a train or a car. But either way, it's about an hour. A straight-line distance of twelve kilometers takes at least an hour! This is unbelievable in today's modern world.

If you take the train, it's the oldest-fashioned green train, with a stop at a train station in a small town the size of Big Walnut Town, and then Linhai City Station. Although the train is very slow, it is relatively safe, and the disadvantage is that there is only one train per day, and there is no flexibility in time.

If you want to be more flexible in time, you can only take a car and take the road, but at that time, the road traffic in Dawalnut Town was not as good, so convenient and safe as it is now.

More than ten years ago, the roads around Walnut Town were all mountain roads, and the mountain roads were extremely dangerous, although the mountain roads here were not as steep as the "road of death" of the Sichuan-Tibet Highway, but they were also limited in strength. To take the mountain road, you must first take the winding mountain road to climb to the top of the mountain range, and then follow the mountain road, all the mountain roads are built with the mountain, twisting and turning, the whole drive is no less than 30 large and small curves, including more than 180 degrees of turns no less than ten. You can only get to Linhai City after getting off the mountain road.

The distance between the two places on the map is only 12 kilometers in a straight line, but the distance on the mountain road becomes tens of kilometers. And the mountain road is high and narrow, the width of the mountain road is only a few meters, barely a single row of two carriageways, two wide cars have to pull over and be careful when they are wrong, a little carelessness will be scraped together, one side of the road is a mountain wall, the other side is a cliff with a large steep slope. On this road, there are more than a dozen car crashes and fatalities every year.

This is not only the road from Big Walnut Town to Linhai, but also the only road from Linhai City. Especially in a place called Laoling, drivers from other places need to hire a local driver to drive there, and they dare not drive it.

This situation did not change until Chen Ziyang was in college. The newly built highway along the river along the Yalu River has been leading to the Dongdan City at the mouth of the Yalu River, now it only takes ten minutes to take a car from Dahetao Town to Linhai City, and it is very safe, the road is flat, although one side is still a mountain wall, the other side is the beautiful scenery of the Yalu River, driving in this green mountain and green water, turning the trip into a beautiful view of nature, compared with the past, it is really a world of difference.

Especially in the Laoling area, there is no need to take the mountain road anymore, a 2776-meter Linhai Laoling tunnel runs through the Laoling Mountains, which not only shortens the drive from Linhai City to nearby Heishui City by nearly an hour, but also avoids the mountain road, so that people no longer have to worry about driving, which is the development and change of Chen Ziyang's impression of his hometown that is the most practical and closest to the lives of the people.

Whether it is Linhai City or Dahetao Town, according to the division of the country, it is a difficult and remote area. On the national map a decade ago, Big Walnut Town was at the end of the thinnest line. The only line that connects from here is to Rinkai City. Because the highway along the river has been repaired for more than ten years, there is now more than one line connecting Big Walnut Town on the map. Such a remote place, even according to the current mode of transportation, is a place with inconvenient transportation and sparse population, let alone a few decades ago.

But it is such a place, after the 918 Incident, but it was held by the Japanese to the death, building roads and houses, and even the Great Walnut Town was built by the Japanese, and even the railway from the Great Walnut Town to the sea was also built by the Japanese. Why? Why did Japan have to go to such great lengths to build such a remote town when it occupied Tohoku? It's for the mineral resources here.

During the Qing Dynasty, Linhai City was one of the largest forest farms in the Qing Dynasty at that time, and the forest farms in Linhai City still exist until now, but now they no longer cut wood. From the cutting of horses by man to the train transportation before the cessation of logging, the entire Linhai Forest Farm is a modern and evolutionary history of China's forestry.

Chen Ziyang remembered that when he was a child, there were so many trees on the mountain here that when he first learned to write, he mistakenly wrote "Linhai City" as "Linhai City", which shows how rich the timber resources here are.

Linhai City is not only rich in timber resources, but also rich in mineral resources. There are all kinds of mineral resources such as coal mines, magnesium mines, lead-zinc mines in the towns and villages under Linhai City, as well as iron ore in Dahetao Town. Even in the mountains across the Yalu River, just across the river from the Eastern Dynasty, there is a rare earth mine that ranks third in Asia. If you don't consider the boundaries between countries, the entire mountainous area of Changbai Mountain is full of mineral resources. And the quality of the resources is very high.

Take the iron ore in Dawalnut Town as an example, the iron content of the iron ore here at that time was basically more than 70%, which was really pure iron lumps, and the iron ore in the iron ore was rich. Otherwise, the Japanese wouldn't have put so much effort into building this place. Of course, such good iron ore has long been mined by now.

More than 80 years ago, the Japanese occupied the three eastern provinces and plundered all kinds of resources everywhere to implement their strategy of "feeding war with war". At that time, there were only three farming families in Dawalnut Town, which herded cattle for a living. Later, the Japanese discovered high-quality and large-reserve iron ore here, so they built roads and houses here, and then there was now Dahetao Town.

At that time, the town of Great Walnut was not occupied by the Japanese, unlike some other towns, but was built by the Japanese. At that time, a large part of the people who lived here were Japanese, so Pu Yi's safety was guaranteed.

Originally, the Japanese wanted to arrange for Pu Yi to go to Japan via Korea from here, but they did not expect that the explosion of the atomic bomb would accelerate Japan's defeat. Before Pu Yi could leave, Japan announced its surrender, and in desperation, Pu Yi announced his abdication here, which is why there is a place where the dragon falls.
