The year flies quickly, and in the blink of an eye, it is Chinese New Year's Eve.

The army of the Yu Zang family has retreated to Lanzhou. But in just two months ago, he and the two Bao Yue [Blind Medicine] families washed almost all the Tibetan parts in the north of Xizhou, so that they had a bad New Year. There are many more bandits on the road, but no one dares to rob Di Dao, and they all rush to other unaffected departments, this Chinese New Year's Eve, the northern part of Xizhou will be lively.

But the Di Dao City [Lintao], where Wang Shao is now, is quiet without any sound. This year's snow was unexpectedly heavy, with a thick layer of snow that could not reach the thighs, and the mountains in the distance and near were covered in silver. A Didao city [Lintao], which has a gray and yellow background, seems to have become an isolated island in the sea of snow.

Han Gang sent a messenger in front. A lean young man in his twenties rode a horse and walked on the road for six days. When he came out, the messenger was dressed like a bear, with fur wrapped around his toes. But all the way to Di Dao, he still froze his hands and feet. Listening to the doctor in the nursing home, at least two toes could not be saved.

In such a difficult situation, Wang Shao did not dare to send more people back to contact. It seems that before the snow melts in February next year, the contact with the rear will only be passed on by stagecoaches that are extremely lossy once every few days.

"Report to the ......" dragged a long shout, and a pawn ran into the public hall after making a report, knelt down and reported to Wang Shaoyu, "There is a team of people in Longxi City. ”

"A team?" Wang Shao asked emphatically, what did Han Gang do when he sent such a person over, and how many more stagecoaches would be consumed if there were more people? Even if he is a strategic envoy all the way, he feels reluctant.

The messenger nodded, "A group of people are coming from the south. ”

"How is that possible!"

Wang Shao couldn't sit still now, and stood up suddenly. Although the southern route is flatter, after all, it is nearly twice as long as the northern route of Bird and Mouse Mountain, and if you take this road, it will take two more days, how can people and horses bear it.

The pawn thought for a moment and added, "They also carry six carts of baggage." ”

Wang Shao was almost about to scold, 'Walking in the snow?!' Sling the bull. ’

Wang Shao didn't believe it, but seeing is believing, and when he walked out of the official office, he saw a team of chariots and horses driving over, and there were indeed six of them in total.

Every third horse pulled a cart, and walked to the yamen with the only bit of ice and snow left in Didao City. The goods piled up high on the car made people wonder how such a heavy car could drive in the snow.

Wang Shao could see clearly that there was not a single wheel on the cars, but two narrow and long planks nailed underneath, and the planks were cocked at the front end. After the carriage, there were two long parallel imprints, dragged straight from a distance. There will be no one else who can make this kind of weird car, it will only be Han Gang, who is good at tricks and even shouts about the avenue.

"This is what Han Yukun made people build?" Wang Shao first asked people to start unloading, and then turned his head and pulled the team leader's colonel over to ask.

Xiao Xiao didn't know anything, but he just handed over the bill of goods and the official document to be signed by the recipient from his arms, along with a letter from Han Gang to Wang Shao.

By the time Gao Zunyu received the news and arrived, the supplies on the six cars had almost been unloaded. The six cars were all loaded with the goods of this year's New Year's Sacrifice Army, and they were basically the usual silver silk tea and wine. Seeing the wine jars loaded on three of the carts, the soldiers who unloaded their baggage cheered. It is impossible to drink without wine during the New Year, and they can't look down on other military funds sent from Gongzhou with great difficulty, but these dozens of altars are the best.

"What kind of car is this?" Gao Zunyu's first sentence was to ask, anyone who has no wheels thinks it is very novel. The deputy chief of Xihe was puzzled and circled around the car.

Wang Shao folded the letter in his hand and answered Gao Zunyu's doubts: "Yukun calls it a sleigh car. ”

"Sled?" This word is very unfamiliar to Gao Zunyu.

"Land travel by car, water travel by boat, mud travel by sled, mountain travel by road. This is talking about what Dayu traveled by when he controlled the water. Wang Shao looked at Gao Zunyu who was dazed, and added, "From "Xia Benji". ”

"When you come up with a name, you always have a source. Han Yukun shouldn't have rebuilt Dayu's travel sled, right? ”

"Almost, now look, this sleigh can also move forward in the mire, and it won't sink in."

Gao Zunyu looked around the car again and said, "It's the same with its practical pack team, right?" ”

"How can a cart pull more of a horse's cargo? When the camel loads the goods, it will be more difficult for the horses to walk. ”

Wang Shao's explanation made Gao Zunyu nod his head again and again, and sighed in admiration: "I really don't know how Han Yukun came up with it." ”

"It's because of the reduced friction. The wheels are blocked from walking on the snow, so replacing the wheels with skateboards reduces friction...... There is also a reference to the principle of snowshoeing, what pressure, pressure. ”

Take the way of nature as an outline and consider how to solve the problem. Instead of being like a craftsman who doesn't seek to understand it, and doesn't know why it is; I just know how, I don't know why. These are the words that Han Gang wrote to Wang Shao in his letter.

Han Gang was reasonable, Wang Shao didn't see it too clearly, and Gao Zunyu was also confused by a bunch of new terms.

Wang Shao handed the letter to Gao Zunyu: "Yukun's letter also drew a picture and designed another kind of ice car, not a skateboard, but two blades. It is said to be used on the ice of the river in winter. ”

"Yukun, is this going to be like a public defeat [Luban]?" Gao Zunyu didn't know what to say, shook his head, and took the letter, "The disciple of the Medicine King didn't do it?" ”

"I don't understand what he's thinking." Wang Shao also shook his head. Han Gang explained in the letter that he had come up with the way of nature, which Wang Shao was very difficult to understand, but after thinking about it carefully, there was still some truth.

Han Gang's mind is not limited by just a matter of opening the side, and after recognizing this again, Wang Shao felt a little deflated, "As long as it's really useful." ”

"Why don't you try the ice car designed by Yukun?" Gao Zunyu looked at the design drawings drawn by Han Gang in the letter, and became a little interested.

"Besides, the river is covered with a thick layer of snow now, and you can't walk on the ice car. These sleds came from the Tao River. ”

"Is it around Zhuniuling and Mabang Mountain?" Gao Zunyu only heard which way this team had taken now, and he was as surprised as Wang Shao, "No one gets frostbite!?" ”

"It's not that it's easy to ride a horse, and it doesn't freeze too much when you sit in the car. And Yukun asked people to design the sleigh car exquisitely, and there is a place to put a brazier under the seat. ”

Before Gao Zunyu came, Wang Shao had already looked at the car up and down, inside and out, and understood the structure inside.

He asked the coachman's seat to be lifted for Gao Zunyu to see, and under the driver's seat, there was a large space, which was divided into lattices by wooden planks. In the middle of the cell is inlaid with a fire-proof copper skin on the inner wall, and a stove is placed inside, the three legs of the stove are embedded in the groove drilled in advance, and the lid of the stove is also with clips, which will not be shaken during driving. Since the middle lattice where the stove is located is hollowed out at the front and back, it can be ventilated, and the charcoal burns slowly in the stove, bringing warmth to the driver in the seat. The charcoal used for the stove was piled up in other compartments under the seats, and after a few days of walking, less than half of it was used.

Gao Zunyu stared at the lattice under the seat of the car and looked at it, and sighed again: "It's really like you're going to lose." ”

"Regardless of whether Han Yukun wants to lose or not, he has finally brought all the rewards for the New Year." Wang Shao looked at the jar of wine placed in front of the yamen, and let go of a lot of worries in his heart.

But at this time, a cavalryman galloped over from the west gate, turned over and dismounted, and knelt down in front of Wang and Gao. ”

"Again?"

"Why are you getting fat?" Gao Zunyu listened to the news, and smiled hideously, "Let's take them as a New Year's gift." ”

"It's probably Dong Yu who intervened." Wang Shao guessed, "Mu Zheng is not a fool, he will not shield Dong Yu from the wind and rain, after all, he will drag his uncle into the water." ”

………………

Mu Zheng didn't have much affection for his third uncle. He himself is the eldest grandson of Luo Zheng, and the position of Tubo Zampu should have belonged to him and his father, but it fell into the hands of Dong Yu by mistake.

When he was young, Mu Zheng also spied on the position that was no longer a noble, but as he got older, he became a little lazy, and he just wanted to keep his Hezhou. But I always had ideas in my heart, so I was always at odds with Dong Yu.

But the current situation can't tolerate Mu Zheng and Dong Yu anymore.

Dong Yu won't try too hard, this is what Mu Zheng knows. After all, in the Pingrong Policy, it is clearly written that it is a union of the Tibetan tribes, not a confrontation. But everyone knows that if Dong Yu can't show the strength that a Zampu should have, then the newly established Xihe Economic Strategy Division doesn't mind swallowing the Qingtang Wangcheng as a soup after eating the main meal in Hezhou.

So weighing the pros and cons, after Mu Zheng bowed his head, Dong Yu still sent troops, a full thousand elite armored cavalry, and promised that if the Song people attacked Hezhou, he would secretly send people to support again. Mu Zheng, a disobedient nephew, is a neighbor, which makes people have a headache, and occasionally makes Dong Yu feel a stomachache. But if he is a neighbor of the Song Dynasty, he will not have a headache and a stomachache, but he will be a cow, a horse and a dog for the Great Song Dynasty!

Having a wolf around you that may fight back at any time is a hundred times stronger than a tiger with a big mouth on its head. Dong Yu was reluctant to confront Song Renmingli, and it was not good for anyone to tear his face, but secretly helping Mu Zheng, he could send people no matter what.
