Outside, the cold wind howled; Inside the house, it is as warm as spring.

The students of the tribe are being taught by the two doctors, the witch deer and the snow, in two separate rooms. The two of them and several other clansmen had much better academic performance, so they were taken out by Ding Qi to be a teacher to teach everyone to study, and Ding Qi was the shopkeeper.

After nearly 10 days of study, in addition to my own surname, I have learned a total of nearly 30 Chinese characters, such as the size, up and down, left and right, front and back, and some other words used in life.

Numbers are learning addition and subtraction within ten, for which Ding Qi also made two fixed whiteboards, on which addition and subtraction are listed separately for everyone to learn. Every day before class, the deer will draw a few random questions, and the person who answers will eat an extra piece of meat at noon. It's not a lot, but it can also mobilize everyone's enthusiasm.

Moreover, Ding Qi divided everyone into three teams, competed with each other, and came up with the method of agitating generals in the army, and the effect was even more obvious. Everyone is vying for the first place, especially not wanting to be the third, because the last place is punished. The content of the punishment is all taught by Dingch, such as push-ups, squats, duck steps, frog jumps, number or text questions, writing with the buttocks, etc. It can not only improve everyone's physical fitness, but also learn what is taught in class, and relax in a funny way, which is entertaining and educational.

In addition to studying, the work or training content of each group was not relaxed, and it was carried out strictly according to Dingqi's requirements. In addition to collecting forage, the red deer group also burned charcoal, and even trained them according to the hunting team in the course of their work. In addition to being responsible for the tribe's eating, drinking, and Lazar, the support team also went to make several kilns of pottery, mainly bowls and containers, and turned all the coarse salt pulled back by Ding Qi into refined salt, and mastered the way and process of refining coarse salt.

There is an abundant supply of food, especially with the seasoning of salt, the amount of food per person has increased a lot, and the originally thin body has quickly become full and strong under the nourishment of food, and the skin of the dish has gradually become ruddy and shiny, elastic and energetic, becoming healthier and healthier, and the physical fitness has been greatly improved under the dual efforts of nutrition and exercise.

Ding Qi, who was the shopkeeper, was not idle, he nested in his wooden house and was making a treasure, a carpenter's tool - a planer.

Tinch had seen a planer as a child and knew its approximate size and construction, so he was ready to try it out and see if he could make it. If you can make it, then you can do a good job of traveling in snowy days.

Previously, Ding Qi had made a two-bladed knife from two spring steel plates cut off from the off-road vehicle, and every once in a while he would take it out to polish the blade on the rough gravel, and now it has been sharpened smoothly and sharp, one side is straight, and the other side is partially ground down from the blade, and the ground part is at a 45-degree angle to the straight side, which can be used as the planing edge of the planer.

The planer is composed of three parts, namely the planing body, the planing blade, the wedge, etc., and what Dingchi is doing now is the planing body. The planing body is very important, not only as the carrier of the planing edge, but also as the planing body for the planing of the wood.

Ding Qi first chose a piece of wood, chopped a rectangle with an axe that was forty centimeters long, five centimeters thick, and six centimeters wide, and then began to cut it little by little with a planing blade, and leveled it with his own mountain knife until the planing body was cut flat, and even found a flat stone as a template to polish on it.

Next, Ding Qi used a charcoal pen to draw the shape and size of the planing bin on the planing plane, and drew the angle of the planing bin on the side, about 45 degrees. After the carving, Ding Qi took the chisel and began to chisel carefully on the planer, even if it was slow, the planer was chiseled well. It is even paired with Tinch's multi-functional Swiss Army knife to polish the bin smooth. It took five days to get the silo ready.

The width of the planer is the same as the planer blade, Ding Qi tried the planing blade, and after jamming a piece of wood, he could achieve the effect of a planer.

The wedge wood is a rectangular piece of wood, not as long as the planing edge, with a thickness that can be firmly stuck with the planing edge, and a triangular notch in front of it so that the shavings can easily come out. This is easier to do, and after mastering the size, it will be made quickly.

The wedge is inserted between the blade and the blade, and the blade is slightly exposed by one millimetre, and the planer is basically formed. Ding Qi held the planer body with one hand and tried it on a wooden board a few times, and it felt okay, but he found a problem, the shavings were not smooth, which was caused by the front end of the planer bin being narrower than the planing blade.

After Ding Qi found this problem, he studied for a long time before he understood the principle, took out the chisel and multi-function knife to adjust the width of the front end of the planing bin little by little, until it was consistent with the width of the planing blade, and then solved the problem that the shavings were not smooth enough. This problem was caused by Ding Qi's assumptions, which showed that he still didn't know enough about planers before, and when he calmed down and found out the principle, he could solve it little by little.

After the problem found by the planer is solved, there is another important thing that the planer has not been installed, that is, the grip. Ding Qi thought for a long time and thought that it was better to use a chisel to chisel out the grip hole, and then insert the corresponding shape of the grip into it to use.

Ding Qi used the small chisel to cut out two square holes in the position he determined, the depth of the holes was about two centimeters, and then inserted the cut grips into the holes and smashed them tightly. At this point, the planer was completely formed, and the first planer of primitive society came out.

After the planer was successful, Ding Qi treated himself. Take out a piece of smoked venison from the stored food, and turn out some dried mushrooms, dried fungus, dried bamboo shoots, shiitake mushroom powder, and some tubers of unknown plants, and prepare to make a good meal and improve the standard of living. Smoked venison is washed and cleaned with hot water, other dry goods are soaked in hot water, the venison is cut into pieces, the lard is the base, after smoking, the venison is thrown in and stir-fried with a pottery spatula, and finally the soaked dry goods are put down to the clay pot together, sprinkled with mushroom powder to improve the freshness, poured into half a pot of water, and finally sprinkled a little salt into it to enhance the taste, and a pot of stewed venison is quickly out of the pot.

It's just that Ding Qi, who had just put down the pot and was about to eat, was caught by Ben and Red Deer, who were chasing after him with the smell, there was no way, they each went to get chopsticks and bowls, and ate with Ding Qi.

Hmm~, I really want to have a bowl of wine at this time!

After Ding Qi's vigorous promotion, it has become the norm for people in the tribe to use chopsticks to eat, and there are only one or two people who can't use them, and most people are already proficient in using them. As you know, if you don't know how to use chopsticks, you will suffer when you eat, and you will only be left with a mess and an empty stomach.

After eating a full meal, Ding Qi called Lu and Xue, Dan, Shi, and Yu to open a small stove for them to learn the next content. These learning contents, for one to five, are much easier than for one to seventy, and five people can learn more things, and these knowledge, they will learn very quickly.

So, after teaching them how to plan next, Tinch went back to his cabin and began to use planers for a major work plan, making skis.

Snowboarding is relatively simple to make, but it requires patience. He sawed down two planks with a saw, basically the same width, slightly larger than the width of his own feet, about 12 centimeters, two centimeters thick, and the length reached the tip of his nose, which is a relatively standard size. But since I'm not a professional snowboarder, I can only make a rough snowboard that allows me to glide on the snow.

After the board was ready, Ding Qi took out the planer and began to plane the two boards, planing them into wooden planks with a flat bottom, about two centimeters thick in the middle of the top, and about one centimeter thick on both sides. Planing on both sides, the standard is to smooth up and down, especially the bottom surface, to ensure that stepping on the snow will not be subject to too much resistance. The thickness left above is to be used for perforated ropes.

After the board is planed, light a fire with shavings, bake the front end of the board on the fire, and keep bending the front end of the board until it is bent at a suitable angle without snow.

The middle of the board is used to step on the soles of the feet. Because there was no proper buckle to hold the two feet in place, Ding Qi had to leave the middle of the board a little thicker, and then burn the board out of an eye with fire. This is a delicate job, and he needs to be very careful, otherwise he will burn the board and start all over again. At the same time, Ding Qi chose to do this in order not to bring resistance to the baseboard.

It took six days before and after, and the two boards were ready, and Ding Qi rolled out four slender ropes and passed through the two holes. After stepping on it, tying the rope to his foot, and walking a few steps in the snow to feel more comfortable, Ding Qi quickly took off his skis and prepared to make ski poles.

Ski poles are easier to make, and a new bamboo about 2 centimeters thick is selected from the bamboo forest, cut and cut into two bamboo poles about 120 centimeters long, but the pole support under the ski poles is not easy to choose and install.

Ding Qi, who racked his brains, finally thought of using the method of drilling holes in the wooden planks to solve the cane support. Select a wooden board about 1 cm thick, cut out two round boards with a diameter of about 5 cm, and burn a hole in the middle to fit tightly on the bamboo joint. These two things don't take much time, especially when compared to the hole in the middle of the snowboard.

You're all set!

Ding Qi took his skis and poles to the top of a gentle slope, and after the rope was tied to his feet, he relaxed and stood with his knees bent in front of him, his weight slightly forward and lower, and his hands clenched on the ski poles. After stepping on the ground twice with both feet and getting used to the snow a little, he pushed his wrists back hard, and under the reaction force of the ski poles, his body slowly moved on the snow and slid down the gentle slope.

As Ding Qi waved his hands more frequently, he skated faster with his feet still and rushed straight down the slope. When he is about to reach the bottom, he uses both feet to adjust the ski into a plow position, buckle his knees inward, put a little pressure on his right foot, and put his weight on his right foot at the same time, so that the left board floats on the snow, slides an arc to the left, and after sliding for a distance, he stops at the bottom of the slope.

YES！

Ding Qi was excited in his heart, and he had not forgotten the skiing skills he had learned in the ski resort before. The first skiing in primitive times didn't start with a fall, which was a good start.
