Father can be an enemy to the country

Everyone drove the ice cart in circles on the lake. Zhu Zhen observed carefully on the shore and saw that they drove the ice bed in various ways. They could push and pull it purely by human power or drag it with ropes.

He saw someone put one end of the rope on the front pillar of the bed and the other end on his shoulder. With a little force, the ice bed sped up like flying. After the speed increased, the driver took advantage of the situation and sat in the front of the car and skated on the ice for a while to save energy.

You can even use a wooden pole to prop it up like a boat. One end of the wooden stick is equipped with an iron spear tip and an iron hook, and has a nice name called "Ling Qiang".

I saw that the handlebar type first used an iron hook to hook the ice bed filled with sandbags, and pulled it forward for a while. When the ice bed became slippery and faster, he jumped on it, stood at the back of the ice bed, and used Ling Qiang's gun. Push forward on the ice. There is no need to exert much effort, just like a dragonfly touching the ice, the ice bed can keep moving forward at a high speed.

Moreover, the handlebar type can also use the spear to control the direction and turn flexibly, just like punting a boat.

"This is a great idea! It is like a car and boat in winter, and it is much faster than a car and boat!" Zhu Di also understood what Lao Liu meant, and praised from the side: "The ice surface is hard and flat, and it is very fast to transport things on the ice bed. It saves effort. During my years in Peiping, I saw people using this thing to transport goods and people every winter until the ice melts in spring. "

"Yes." Zhu Zhen nodded. Each of those sacks contained a hundred kilograms of sand. He saw ten bags stacked on the larger ice bed, and they could still be opened steadily without much effort.

"Is this thing difficult to learn? How long does it take for a novice to get on the road?" Zhu Zhen asked again.

The fourth child pulled him off the ice and said with a smile: "Didn't you say that true knowledge comes from practice, and talent comes from struggle? You will know if you go down and learn for yourself."

"Uh... Okay." Zhu Zhen had actually been feeling itchy for a long time, but he had the burden of being an idol and was afraid that not skating well would damage his image. But in front of the fourth brother, he was still a younger brother, so he half-pushed him and left the field.

'Xiong Da' had someone bring an ice truck over, and he personally taught 'Xiong Er' how to set up the ice bed in the middle of the lake.

Zhu Zhen experienced it personally and found that it was indeed not difficult. At the beginning, he could not grasp the direction of exerting force. The ice bed did not move in a straight line and his speed could not increase. But in just a few minutes of tea, he found the doorway, became more comfortable with the operation, and his speed increased.

I saw him standing at the back end of the ice bed, holding on for a moment, the ice bed made a chirping sound, and then flew forward. The wind blew past my ears and temples at a speed similar to that of a galloping horse, but very steady.

This is just for walking in a straight line, you have to learn other things like braking for corners and so on.

After almost an hour, he was basically able to control this ice car the size of a single bed. Of course, being able to make emergency stops, drift, and cross obstacles on the ice like the fourth brother could not be achieved overnight.

But it's just a shipment, and it doesn't require so many fancy technologies.

When he returned to the shore, Zhu Zhen asked the handlebar: "Is it difficult to make this thing?"

"What's so difficult about that?" Handlebar Shih replied with a smile: "It's actually just a wooden board with two rows of short legs underneath, and two long wooden legs underneath the short legs. A carpenter can build several cars in one day. "

Zhu Zhen squatted down and carefully observed the ice cart. He saw that the two long logs in contact with the ice were like the legs of a sled. The principle of action is similar to that of a sled. It is actually an ice sled.

"I see that the bottom of your crossbar is covered with copper skin." He touched the bottom of the crossbar and the yellow metal skin wrapped around it.

"This is something from the General's Mansion, and of course it has to be more refined." Handlebar Shi explained hurriedly: "But in fact, the effect is the same if you use iron sheets or animal skins. It doesn't even cover anything, just polish the crossbar smooth. , can slide just as well.”

"Okay." Zhu Zhen nodded happily, stood up and pointed at the handlebar and said, "Let's take a look."

Ma Sanbao took out a golden bean and threw it to the handlebar.

Handlebar Style burst into laughter, holding the golden beans in both hands, and kowtowed to express his gratitude.

~~

Not only that one handlebar style was rewarded that day, all the handlebar styles received the ten taels of silver promised by the Sixth Prince. And it only took one hour to complete the one hundred laps he required.

Zhu Zhen had someone measure it and found that a circle around the lake was exactly one mile. In other words, the distance traveled by the ice bed in one hour was one hundred miles.

This is not the speed of the ice bed, because firstly, it is fully loaded, and secondly, many ice beds are traveling together, which will inevitably hinder each other. Furthermore, frequent turns make it almost impossible to increase the speed, which also greatly affects the speed of the ice bed.

But for Zhu Zhen, such a result is meaningful because it simulates to the greatest extent the state of an ice truck team traveling collectively on a winding river. Of course there won't be so many turns in the river, but there are much more ice trucks, so the speed inside and outside should be pretty much the same.

However, after finishing the lap, the conditions of the handlebar players were quite different. Those who relied on human power to push and pull the ice cart were obviously too tired to lift their legs and hands, while those who used a spear to control the ice bed were in much better condition. None of them were out of breath, their faces weren't red, and they could obviously continue to slide.

So Zhu Zhen asked them to continue skating... Of course, the Sixth Prince would not let their efforts go in vain, as this was a separate reward.

The purpose is naturally to test the driver's endurance. As a result, none of them complained that they were tired until dark. They all said that if they could see the road clearly, they could skate all night long.

"This is nothing to show off." Zhu Di told Zhu Zhen: "The handlebars here in Peiping are skated from morning to night. When busy, they even skate while eating, because it doesn't take much effort at all."

"Okay!" Zhu Zhen nodded happily. Battery life is actually more important than short-term high speed.

After dinner, the two brothers plunged into Xu Da's study, secretly drinking the wine hidden by their father-in-law, and continuing the discussion enthusiastically.

"For safety reasons, we can only drive during the day. The weather is short in this season, but there are still five hours of dawn. Excluding meals and rest in between, as well as various emergencies on the road, let's assume that he walks for four hours a day. That's four hundred miles!" Zhu Zhen said solemnly.

"That's really a shame." Zhu Di was licking the salt water duck neck and dumbfounded: "Normally, the baggage transportation is twenty or thirty miles a day, but your speed is ten or twenty times! It's two thousand miles from Nanjing to Peking. , you can arrive in five days.”

"But it is estimated that tens of thousands of ice trucks squeezed together will definitely not be able to reach this speed." Zhu Zhen said solemnly: "But I estimate that half the speed should be available."

"That only takes ten days!" Zhu Di said with joy from ear to ear: "What am I saying? There is no problem that you, the sixth one, cannot solve."

"Fourth brother, don't be too optimistic. Don't forget that we can't use the ice bed the whole time." Zhu Zhen reminded him.

"That's right." Zhu Di patted his head and said, "The Yangtze River does not freeze."

"Generally speaking, the Huaihe and Qinling Mountains are connected by a line." Zhu Zhen drew a red line on the map and said solemnly: "Normally, the south is not icy, and the north is icy."

"So, you can only use the ice truck after crossing the Huaihe River?" Zhu Di touched his chin and looked at the map.

"Not yet, the ice layer needs to be thick enough, so we have to continue to the north. Normally, it will be almost the same as entering Shandong." Zhu Zhen said slowly: "But it is extremely cold this year, maybe we can go further south, because of this It’s so big that we need to send someone to conduct an on-site investigation.”
