Ding Gongchen was a great scientist of this era, at least from the Qing Dynasty, who helped the Qing court improve the gunpowder formula and manufacturing process during the Opium War, so that the quality of gunpowder in the Qing Dynasty caught up with or even surpassed the gunpowder of the British army, which is a very remarkable achievement.

During the Opium War, he also designed a number of ship models with Ding Shoucun and Zheng Fuguang, and drew relevant design patterns, including and outside.

In addition, he also worked with the craftsmen to design a model of a steam locomotive, one foot nine inches long, six inches wide, with a load of thirty pounds, and the boiler and fuselage were made of copper, called "Little Hot Wheel Car", which caused a sensation in the upper circles after being displayed in Guangzhou.

It took a long time for the gentry present to remember that the iron bump in front of them was only large in size, almost exactly the same as the small steamer shown by Ding Gongchen, and it seemed to be the real train.

The men were so frightened that they continued to look and found that there was a large crane commonly used in the port where the truck was parked, unloading a large amount of goods from the vehicles behind the truck, and many people came forward to disperse the goods to various places.

These goods, mainly firewood, as well as a large number of logs, as well as a lot of raw and cooked meat, some intelligent people immediately realized that these mountain-like goods of the original Sanyuan Temple came from in this way.

Li Xian and Wang Jiuxuan also had no intention of restraining them, so they took these people over and carefully watched the locomotive from a close distance to satisfy their curiosity.

These decent people of Guangzhou swarmed up, carefully stroking the locomotive and the freight vehicles hanging behind them, and finally understood that these were real trains that were hundreds of times larger than the steamer cars.

The vehicle hanging in the back is actually not much different from the usual flatbed cart, but it is made into a boxy box with a wheel underneath, which can easily carry goods on the wooden rails.

In the end, the curiosity of these gentry was greatly satisfied, and new doubts came up, although this train was cleverly designed and huge, but there were always traces to follow, so where was this train originally hidden?

The stone building was transparent from front to back, and I couldn't figure out where such a big iron lump was in the first place.

Among the people who came here, there were many families with a real long lineage, and they knew something about the cultivation world, and they immediately thought of one thing, but because the answer was too ridiculous, they didn't dare to think about it.

"Those foreigners always say that this train is amazing, it turns out to be such a big object, it is really a long time to see. It's just that where did this train come from, can the two marshals tell me one or two?" After all, there was a bold one who had the courage to ask Li Xian and Wang Jiuxuan for advice.

"It's a long story, a few well-informed people must have guessed it, and I'm afraid the others will have to see the real thing to really understand.

Can you come with me and enter the blessed land that my Sanyuan Temple has been operating for hundreds of years to have a look?" Wang Jiuxuan laughed, made a gesture of invitation, and then walked towards the stone building by himself.

The Great Grandmaster-level Elder of the Three-Yuan Temple was still maintaining the blue aperture, and Wang Jiuxuan raised his foot and stepped over, and the gentry behind him were startled, but they had no other way but to follow into the aperture.

When everyone entered, they found themselves in a completely new world, and there were still two wooden rails under their feet that were winding forward, but everyone was no longer in the three-element view, but in a completely different world.

At first glance, it looks very similar to the Sanyuanguan side, there are also a lot of wood and materials piled up, and there is your train stopping in the open space in the distance, and there are a bunch of people loading various materials into the carriage behind the train.

It's just that the Sanyuan Temple is just a Taoist temple in the suburbs of Guangzhou, and the terrain is relatively flat, but the mountains in the distance here are undulating and majestic, and the big trees are lush, but it is not the scenery that the Sanyuan Temple can have.

Everyone suddenly felt a huge shadow on their heads, and they were startled, and they couldn't help but look at the sky, only to find that a big bird with wings of more than ten feet flew through the sky, casting a huge shadow.

Then, people found out that there were actually several suns in the sky here, which made the weather unusually hot.

In the distance, there are more than a dozen long-necked dragons carrying a large number of goods to this freight yard, the head to the tail is five or six feet, and at a cursory glance, there are at least tens of thousands of catties, which can be called a behemoth.

There were a few timid gentry who felt that their legs were weak and they were about to be frightened on the spot, and they barely stood up with the support of the people next to them.

"All of you here are well-informed, and you know that my three-element concept has existed for hundreds of years, and it is this three-element blessed land that depends on it.

It's just that there are many people who have heard of the blessed land, but few people have actually come to it, so I am afraid that I never thought that the blessed land would be like this.

I didn't say it, since I came here and I was a guest, let me be the host today and entertain a few people. Wang Jiuxuan laughed and said.

Li Xian smiled slightly, but did not speak, when he entered the blessed land for the first time, he was also greatly impacted, so he could understand what the mood of these gentry at the scene would be.

Under the leadership of Wang Jiuxuan, Li Xian and the officers, these gentry barely calmed down and followed people to visit the blessed land.

Since the Qing court banned the transportation of materials to Guangzhou, the life of the people in Guangzhou has gradually become difficult, but both Wang Jiuxuan and Li Xian can calm down, and do not rush to attack the city and seize various resources, the biggest confidence lies in this three-yuan blessed land.

Li Xian has wanted to develop this three-yuan blessed land for a long time, but there are many obstacles to the transportation of materials from this three-yuan blessed land to the main world, first of all, the living creatures on both sides cannot come and go freely.

In other words, animals such as horses and cows in the Overworld cannot directly enter the blessed land, and once they enter, they will be completely lifeless, and the dinosaurs and ancient creatures in the blessed land cannot leave the blessed land, otherwise they will die immediately, and there is no reason to find it.

Xuan Zheng et al.'s explanation for this is that the rules of the avenue on both sides are different, only human beings can come and go freely because they are the primates of all things, and other creatures cannot come and go alive, only in very special circumstances, with a small probability that the living creatures on both sides can occasionally survive, but there is no law, purely by luck.

When the circulation of materials on both sides is not large, it is not enough, and once the quantity goes up, it can only rely on manpower hauling, which will greatly limit the transportation of materials.

Li Xian's solution to this problem was to buy locomotives through European merchants and make their own carriages to hang up, so that the transportation of goods would not be too restricted.

However, at 35 kilograms per meter of rails, one kilometer of four rails in and out of two tracks costs 140 tons.

However, the train should not be too heavy, the size of the carriages and the load capacity should be reduced accordingly in order to reduce the load on the wooden tracks, and the train would use charcoal instead of coal.

Fortunately, under the auspices of Li Xian, the Huaxia Army's industrial and technological capabilities were greatly improved, and they finally overcame a variety of technical difficulties, paved the wooden tracks, started the trains, and realized the transportation of bulk materials between the main world and the blessed land.
