Obviously, a misunderstanding cannot solve the problem. Fortunately, Galdan is not a fool. He took out two imperial silver dollars from his pocket and handed it over. After all, he was allowed to approach the ice sled. Galdan studied next to the ice sled for a long time to figure out that it was because there was an ice sled at the bottom of the ice sled to move forward quickly on the ice surface, but he only understood this.

Until the evening, Galdan had never understood all the secrets. He wanted to understand the entire principle and manufacturing techniques of this thing. The reason was very simple. Whether it was Tibet or Tianshan North Road, winter was cold weather. If he could have the ability to sail on the ice, it would definitely be a good thing.

Galdan was thinking about these things, and was pulled into the cart shop by the manager. He squatted beside the stove, frowned, and thought, as if no one was around, which made everyone laugh at the caravan. But Galdan didn't care at all, but asked those people if they knew ice sleds, but everyone knew that the answer was that because caravans could not do without this thing in winter. After all, most of the towns outside the empire were along the river. Galdan immediately asked about the various secrets of the ice sled, but everyone could not answer four or six.

A oldest groom walked into the big house, slapped off the ice on his beard and eyebrows, picked up a piece of sweet potato and baked it by the stove, saw everyone laughing and asked, "What are you talking about?"

Someone immediately told Galdan's question and made fun of it: "Chahun is the most curious Tartar I have ever seen. I have to ask why the ice sled can walk like flying with ice skates. This looks like the students of Humaer City School, haha."

Galdan didn't care about his cancellation and asked the groom: "Do you know?"

The groom shook his head, and Galdan simply took out a silver dollar from his arms and said, "Who can explain it? This coin is his."

Everyone shook their heads, but they couldn't tell clearly. The groom peeled the sweet potato skin and ate the sweet potato meat and said, "I heard that the ice sled is related to His Majesty the Emperor. It is said that the emperor led his troops to Yongning to open up the pass and fought with the Qing Dynasty in Ningguta. In order to maintain the smooth transportation between the frontier and Yongning in winter, a sled transport team was established. A sled craftsman installed the ice sled on the bottom of the sled, which became an ice sled. For this reason, the emperor also rewarded the craftsman with more silver."

"Old Chen, just brag, the emperor, that's the emperor, can the man in heaven give a reward of a stinky iron?"

"that is."

A group of people echoed, all of whom didn't believe it. However, Galdan quickly asked whether it was true or not because he heard the news about Li Mingxun for the first time. The groom only heard that he believed it was true, but he couldn't come up with any evidence. Galdan asked the manager of the caravan, and the manager smiled: "I don't know whether it is true or not, but the craftsman's luck is really bad."

"After receiving the reward from the emperor, are you not lucky?" Galdan asked in surprise.

The manager said: "If he had invented the ice sled in the past few years, he would not have just a little reward, but he would have no worries about food and drink for the rest of his life."

"What does it mean? Is it because after the emperor ascended the throne, he became more generous to craftsmen?" Galdan asked.

The manager smiled: "Chahun, you don't understand the Empire. The Empire had a patent bill a few years ago. The Patent Bill is for whom who invented it. Let's talk about the inventor of the ice sled. For more than twenty years, he only got dozens of taels of silver. But if he had such an invention now, according to the Imperial Law, the workshop for making ice sleds would have to give the inventor part of the silver. Outside the entire pass, the number of ice sleds was more than 100,000. Even if one coupon was given to the inventor, it would be several thousand taels, and there would be investments every year in the future."

"There is such a thing?" Galdan was amazed at the ear: "Then if I invent something like an ice sled, wouldn't my descendants be able to live a good life?"

The manager shook his head: "This is not possible. The patent bill will be protected differently depending on the invention. It will be only twenty years. In twenty years, anyone can use it, so there is no need to share the wealth of the inventor. In twenty years, it will only protect two generations of wealth."

"That's a bill!" Galdan clapped his hands and said.

Speaking of this, Galdan was even more curious about the empire's emperor Li Mingxun, because among the knowledge he knew, neither the Central Plains dynasty nor the other civilizations he knew, there were no laws like the Patent Act. For the emperor who implemented and recognized such laws, Galdan couldn't help but want to know more about the emperor who implemented and recognized such laws.

Galdan did not fall asleep this night, not because the room in the Tatongpu was full of snoring and smell of stinky feet, but because he was thinking about something. On the next day, when the manager got up and prepared for the caravan to start, Galdan found him and made a decision beyond the manager's expectations: "Prophet, I am not going to leave with you, I want to stay here until I figure it out."

The manager was shocked to see him say this, because his task was to send Galdan, who was named Chahun, to Humal, instead of staying in the snow and ice. The manager quickly pulled him into a room and asked, "Why, why do you do this?"

"I want to figure out my doubts." Galdan said seriously, with a desire for knowledge on his face.

The manager was surprised: "What do you have to do with doubts? Isn't it just an ice skate?"

Galdan coughed lightly and said, "There are many things here that I can't understand, such as the ice sled, apart from the ice skates, why can they use sails as power? In the north wind, why can those ice sleds move against the wind?"

As he said that, Galdan pointed to the stove on the stove beside him and said, "And this, what kind of great craftsman can make iron into iron sheets larger than cowhide, and then roll them into such a round tube. There is no way to be beaten at all. It seems that he has grown into iron sheets by nature. I must visit this great craftsman. Do you know that if such a stove is placed in a temple, everyone will think it is magical powers..."

The manager was so angry that he said, "You can't find the craftsman here again. The person driving the ice boat can't tell you why the ice boat can go against the wind. Let me tell you this, the processing of iron is not magical magic, but requires large machinery. The principle of sailing against the wind requires profound mathematical knowledge to explain. All these knowledge is not here, nor does Humaer. Only by going to Yongning City, Vladivostok and even the capital can a person with profound knowledge explain everything."

"Can you help me find that scholar with profound knowledge?" Galdan held the manager's hand.

The manager said: "It's not a scholar, but..." Looking at this face full of curiosity, the manager simply gave an explanation that the other party could accept: "Just like a real monk must be in a magnificent temple, that advanced scholar cannot be found in the border areas, nor can I be contacted by me a mere smuggling merchant. I can only tell you that you have to go to a big city to find out the truth. I can also tell you that this knowledge does not belong to a certain profession or a certain class. Every citizen of the empire has the opportunity to learn it. Chahun, don't you want to learn it?"

This is really a slight slight point in Galdan. Didn’t he just want to learn these things?

Galdan had to sigh: "Okay, I'll go with you, but it's a pity that I can no longer explore the beauty of the ice boat in person, and I don't know when I will have such an opportunity again."

The manager smiled: "Where is this nonsense? In this season, no matter what caravan it is, how can you get from here to Humal without the ice boat? Do you have to ride a camel all the way and walk in the thick snow at knees?"

Only then did Galdan realize that his caravan also wanted to use ice boats, so he immediately went to help pack up his things happily. The caravan rented five ice boats at the dock and hired a guard to transport the goods to the ice boat. He hung a large string of ice trucks behind him, raised sails made of thin wood, and used the bitter north wind to zigzag movement on the wide river surface. He soon entered the Erguna River upstream of Heilongjiang. This river was quite smooth on the Hulunbuir grassland, but after leaving, it passed between mountains and ridges. Many sections of the road, because the ice surface was downhill, did not need to rely on wind power, and could slide forward with just power, so there was also a brake device to avoid hitting the steep slopes on both sides.

Sometimes, the ice surface is really steep, and there are even waterfalls. If you want to unload the goods, turn the ice sled into a sled. Galdan and everyone will unload the goods first, then turn the guide rails under the ice boat, remove the screws that fix the ice sled. Once you smash it with a wooden hammer, the ice sled can be removed, leaving only a thin slit on the guide rail made of hardwood. Then, fix the prepared guide rails on both sides of the rails with screws and nails. This way, widen the guide rails to prevent the goods from being heavy and falling into the snow. After cleaning up, load the goods, drag the sled and move forward on the snow, and avoid the steep areas with huge drops.

After this section of the road, change the sled to an ice sled and move onto the ice again, and you can reach Humaer City directly.

It took ten days to get from Hulun Lake to Humal City. After the sled turned into an ice sled, he could move forward again by controlling the wind, saving a lot of manpower. The manager arranged everything and continued to move forward. He wrapped his whole body in a sheepskin coat, put on a cotton hat and a wool scarf, and hugged on the ice boat to rest. He saw Galdan on the side huddling in the corner, holding a set of screws to play with it, unloading the nuts, and playing with it constantly. The manager smiled and ignored it. When he first saw this thing, he had been playing for a long time.

"Brother Chahui, let it go. It's too cold and my hands are frozen carefully. I will camp at night and play when I'm roasting the fire." said the manager.

Galdan didn't hear it at all and was still playing with it. Until the manager pushed him, Galdan woke up. The manager asked what he was thinking. Galdan said, "I was thinking and using screws to design something that can be converted freely without unloading the goods."

The manager smiled: "Then the relationship is good. If you can invent it, you will be able to eat and drink delicious food in the future, but how is that possible?"

Galdan said, "How is it impossible!" As he said, he picked up a wooden strip, and a gap had been scraped on it, and a piece of wood was inserted on it. Galdan said, "Suppose the wood chip is an ice skate, as long as the gap is dug deeper, when it needs to be turned into a sled, you only need to pull out the screws, and the goods on it will be pressed back to the depth of the gap. So there is no need to unload the goods?"

"When the sled is turned back into the ice sled, how can the ice sled come out?" asked the manager.

Galdan scratched his head, but he didn't think about it. Although he immediately thought that he could leave a piece and pull out the ice skate, in this case, he still had to unload the goods before he could replace it, which was inconsistent with the original intention of the design.

"I'm not thinking well, but I'm going to invent this thing sooner or later!" Galdan said with great enthusiasm.

The manager laughed and said, "You can calm down for a while, this is completely useless."

"Who said it's useless? You are jealous of my invention!" Galdan said angrily.

Along the way, Galdan was perfecting his invention and even made a simple model. His modification plan was more refined, which was to turn one ice skate on the guide rail into two and fix it on both sides of the guide rail. When the ice sled turned into a sled, first stuff wooden strips between the two ice skates to let them be subjected to force, so that the ice skate can be removed. When the sled becomes an ice sled, it is even simpler. You only need to dig a trench on both sides to install it.

Galdan, who figured out all this, did not say to the manager again, but asked about the patent bill, how to register, how to take effect, and how to protect. The manager was not only seen in the newspaper, but he did not understand it, but just asked him to go to the yamen to handle it. Galdan had to give up, but he made up his mind to keep the secret and apply for it himself, saving the group of people who were being stolen his invention. Galdan was not for money, he was to prove that he was not stupider than the Han people!

But Galdan's plan and dream that had been brewing all the way was completely shattered the moment he entered Humal City, because at Humal City Wharf, he already had equipment that could replace the ice skates without unloading the goods. It was similar to a manger, full of ice, and there were slopes at both ends. People directly pulled the ice boat and passed by it. On the abdomen of the ice boat rack, there were two ice skates. After climbing the thing along the slope, the entire ice sled was set up, and the two guide rails of the ice sled were no longer under pressure and could be disassembled freely.

When Galdan saw this thing, he immediately felt his heart was broken and almost cried. He felt that his thoughts for seven or eight days had been wasted. He angrily pulled the manager: "Why didn't you tell me that there was already such a thing?"

The manager was surprised: "Didn't I say that, what you think is a useless thing!"

"But...but..." Galdan's face turned red with anger, but he couldn't complain.
