Wooden oxen and flowing horses, according to legend, were designed and manufactured by Zhuge Liang during the Three Kingdoms period and were used to transport grain and grass.

It is divided into two types: wooden oxen and flowing horses, and is capable of long-distance gallops, providing food for an army of 100,000 and carrying out large-scale transportation.

A legendary era, a legendary figure, so that the name of this means of transport has also been handed down, and it has also become a legend.

Until Xu Wen's time, it was still not completely clear what these two means of transportation were, and there were only some vague inferences and designs based on rumors.

But right in front of him, in this dark cave, watching the two small burdens disappear from his eyes—in fact, he couldn't completely see how it disappeared—but Xu Wen suddenly thought of this word and subconsciously called out.

"Wooden Ox Liuma, do you mean the one designed by Prime Minister Zhuge Cheng?" do you think this is it?" Wu Keming touched his chin and groaned.

Xu Wen didn't know the history of this world, but now it seems that at least this aspect is the same.

"I don't know, I just thought of it. Xu Wen calmed down and shook his head.

Wu Keming didn't ask why, he took out a torch from the hole next to him, lit it, and led them inside, introducing as he walked: "I also found this place by accident." As you can see, there is no road to the platform, and it is difficult to find it up or down the mountain. I had a stone wall dwelling, and then I wanted to repair it on a whim, and when I got up, I was worried about the inconvenience of the road and how to transport the materials. ”

His torches seemed to be specially made, and the light was stronger than the ones in Xu Wen's hands, and they could illuminate a wider area.

He stretched it out to his left, and Xu Wen's gaze followed the direction of the torch's gesture.

It was too dark for them to see the road, and they didn't have time to see more details, but only then did he realize that the surrounding stone walls had been treated a lot, leaving traces of many mechanisms.

At the same time, some of the stone bricks were embedded with copper rings, and the copper rings were corroded, and there were some black marks on them, as if something had been bolted to them at one time, and then rotted on them for too long.

And what is running now is the more intact part of it.

It can be seen that it was once part of the whole system, but fortunately it was preserved, and then restored to become independent and functional.

"Later, I accidentally discovered that there was such a road hidden in the Stone Wall Curie, and there was such a mechanism in this road, so I knew what kind of miraculous means the ancestor who built the Stone Wall House in the first place. Unfortunately, I was able to recover a small part of it with my friends, which can be used to transport some smaller, lighter cargo. However, the 10,000-pound boulder moves at will, and it is estimated that it can only be realized by restoring it all. Wu Keming's tone was leisurely, and his face was yearning.

In fact, for him, the person who built the stone wall house was just a craftsman, a relatively low class.

But Wu Keming naturally called him an ancestor, and his tone was very admiring.

"Ten thousand catties of boulders move as you like......" Xu Wen repeated this sentence, imagining that scene, and unconsciously felt a little excited. "That hanging basket down there is also part of this mechanism?"

"Yes, that one was also repaired by my friend, but he said that with his strength, he can only do it so far, which is a pity. Wu Keming said.

As they walked forward, the mechanism kept making a clattering sound, which kind of dispelled a lot of the gloomy atmosphere here.

Xu Wen listened to Wu Keming while walking, and observed the surroundings attentively.

It wasn't for nothing that he had made that association before.

The machine in front of me is a mixture of copper and wood, and its shape is very square, not like a cow or a horse, but it is about the same size.

It has wheels under its belly, and the wheels are very strangely shaped, looking a bit like the small carts that can climb stairs seen in the other world.

So as it moves forward, the wheels roll forward.

This makes the machine look a little cute when moving forward, but it can be easily overcome when encountering some bumps that are not flat, which is very useful.

Of course, it is also because of this characteristic that Xu Wen thought of the legendary wooden ox flowing horse.

He had curiously read some relevant information, although there has been no fixed description of the wooden ox flowing horse, but in the relevant speculation, it can walk automatically, can step over the ladder steep slope and other places that are not easy for ordinary vehicles to pass, which is consistent with the machine in front of him.

However, after careful observation, Xu Wen found a huge difference between it and the legend.

There is a track under the wheel of this machine in front of you, and it goes along a fixed track.

And the legendary wooden oxen and horses travel thousands of miles and transport millions of grains and grass, it is definitely impossible to have a track.

However, he observed for a while, but still did not understand the principle too clearly.

What is its power, and how is it driven?

I don't know the details of the outbound journey, but I know the details of the return journey, and I usually feel that it will pass a little faster.

It felt that they hadn't been gone long this time, and they heard Xu Sanjiang Wangfeng's voice. They were arguing about whether to wait a little longer or send someone to Xu to ask them.

Seeing them come back, a group of people breathed a sigh of relief together, and then saw Wu Keming again, everyone was surprised: "There is a road on the other side?"

"Nope. Xu Wen shook his head and briefly explained the situation, everyone was surprised and curious, Xu Xihuai opened his eyes wide, and called out in surprise: "If you say this, if you repair the upper and lower organs, will you be able to transport the stones of Tianyun Mountain, so that Feng ...... Can someone from the outside use it?"

In recent times, Xu Xihuai seems to have returned to normal, but Xu Wen often notices that he will stay quietly alone, writing and drawing in front of a thick piece of parchment, pondering something.

Xu Wen didn't need to pay special attention to see that he was designing the house.

Stone houses and private houses can be seen at a glance for what they were designed for.

Xu Xihuai still can't forget the place where he was born.

But no matter how good the design is, it still can't solve a key problem, which is the materials used to build.

One of the biggest problems with stone buildings is this.

It is not easy to transport stones, and it is best to use them in large quantities.

However, it is a matter of luck to use local materials, depending on whether there are good materials nearby and convenient locations for them.

Fengchun is not far from Tianyun Mountain, it stands to reason that Tianyun Mountain is a very good stone field, but Tianyun Mountain is too steep, as far as it seems now, the stone is located at a distance from the foot of the mountain, and the granite is still extremely difficult to use.

Looking at it comprehensively, there is no need for Xu Wen to explain, Xu Xihuai can also understand why, after the accident in Fengchun, the imperial court would rather risk a sandstorm to transport materials from outside than take them from Tianyun Mountain nearby.

Without him, it is just technically impossible to do it.

And now, hearing this miracle, Xu Xihuai seems to see a new hope, and he can't help but be excited.

"Impossible. When Xu Wen spoke, Wu Keming was busy taking the two burdens off the machine, and finally had time to turn his head and say a word, and poured cold water on Xu Xihuai with one sentence.

"I've been working on this thing with my friend for a long time, and that's the best I can do. The structure and principle of the rest of the part are different from the remaining parts, and there is no clue to be found. ”

Xu Xihuai's smile froze instantly, but Jiang Wangfeng suddenly said: "This is impossible, how can something made together be completely unconnected?"

"Yes. Xu Wen agreed, "Xiao Feng is right, it is impossible that there is no connection." Now that some of it has been repaired, the rest should be able to be deduced as well. ”

Hearing Xu Wen say the same, Xu Xihuai immediately relaxed and smiled again.

"No way. Wu Keming still said very firmly, "Do you know who that friend of mine is?

"Tiangong?" Except for Xu Qian, everyone present gasped together, in awe!
