Passing through the training area of the Wild Wolf Brigade, Sima Pianpian entered the interior of the North District, where a large group of people were gathering and busy.

"Star." Sima Pianpian approached.

The busy crowd straightened up and greeted her one after another.

"How's it going?" Sima Pianpian walked directly to the primitive man, looked at a large pile of objects on the ground and asked.

Xinghui said: "Chief Hui, all the pottery pipes have been fired, and they can be screwed directly when they are laid, the waterwheel has been successfully tested in the planting area, and now it is being enlarged in the same proportion, and the materials used for construction are also the hardest wood, but ...... After it was built, the weight of the entire waterwheel was ......"

Sima Pianpian: "It's okay, just make it according to the proportions I said, and I will take action when I install it." ”

Star: "Yes! ”

Some time ago, before she went out, she handed over the waterwheel and pottery pipe to Xing Lai to be responsible, after countless experiments and failures, finally achieved small results, and Sima Pianpian did only analyze the principle before, and occasionally sent emails to point out when they encountered problems, most of them were the credit of primitive people's cooperation, and saw their seriousness and hard work, Sima Pianpian was very pleased.

The waterwheel is an irrigation tool, whether it is agriculture, animal husbandry or primitive people's domestic water, it can be used to facilitate this tool. Several large and small waterwheels are installed at the junction of lakes and rivers, and water is taken by water wheels, and water is carried in pottery pipes, and the guò tunnels are used to reach every household.

Most of the corners of the house have a water draw, one end is a special animal skin, the animal skin part is inserted into the tunnel pottery pipe, one end is the pottery outlet, half a meter long hollow pottery pipe plus a bend, similar to the appearance of a faucet, exposed to the surface, there is a leather valve at the junction of the two, the valve is controlled by a wooden stick, every time the wooden stick is acted on up and down, the air will enter from the water outlet, acting on the animal skin, the animal skin instantly produces a suction, the water around it is sucked back, and then the water will come out of the water outlet, repeat a few times, You can fill a whole basin, although it is not as convenient as tap water, but it is much more convenient than using the shoulder to pick it before.

Sima Pianpian no longer disturbed everyone's work, and wandered around alone, a lot of trees were piled up and dried in the North District during this time, all of which were transported from outside by the hunting team, preparing to burn charcoal in a few days, time passed so quickly, and it was winter again in the blink of an eye......

When she came to a warehouse, Sima Pianpian's mental power was swept away, and a look of surprise appeared on her face, she called a person from the pottery group and asked, "These are all collected by you in the No. 1 warehouse?" ”

The man shook his head and replied, "No, chief, this is what Master Yin told us to keep, and he said that it should not be wasted, and that you may need it in the future." ”

"Oh...... It's okay, you go get busy. Sima Pianpian touched her nose, she was a little speechless about the title of "Lord Yin" in the primitive population, I don't know when it became popular for primitive people to crown the title of "Adult" after those managers, such as Lord Wanhuo, Lord Xing, etc., she knew that it should have originated from Wanhuo's title of her "Chief Adult", as for when Wanhuo learned it...... can only think that Sima Pianpian occasionally mentioned it when telling the story, and she remembered it firmly......

What was kept in the warehouse was the broken rope nets that were removed from the temporary camp after the original station was built, and they filled an entire warehouse......

Sima Pianpian smiled slightly, she remembered that she said in class a long time ago that many things can be turned into treasures as long as they are used properly, and the cat has always remembered it......

Looking at these ropes, Sima Pian pianpian groaned for a moment, and then his eyes lit up, and he immediately took action.

She set up a large cauldron, took some rope vines and put them in it, added water and boiled them over high heat, and after boiling for more than an hour, the rope vines showed signs of softening, but it was not enough. Sima Pianpian searched the database, then took out the rope net, took her machete, directly chopped the rope net, and then threw it into the pot to boil, so that it boiled for more than three hours, during which it was pounded with a wooden stick from time to time, and finally became a pale cyan slurry.

Sima Pianpian's face flashed with a hint of joy, and after the slurry cooled, she picked up a simple mesh sieve that had just been made next to her, a thin animal skin, on which many fine holes were poked with needles, and then clamped up with wooden strips on all sides and fixed into a frame, forming this mesh sieve. She took the mesh sieve and carefully scooped the pulp, repeated it several times, but it was not even enough, she squinted, and her mental power slowly released...... "Perfect!" Sima Pianpian secretly praised without blushing, and he was also drunk by using the method of cheating to obtain the first-hand technique formed by the ancestors who had been honed for a long time......

The next thing is to dry naturally, but after waiting for a long time, except that there is no more dripping, it is not much dry, Sima Pianpian glanced at the blue and white sky above her head, and despised herself, how could she forget this stubble? If she was seen by the members of the pottery team, she, the chief, would probably be laughed at...... In winter, the sun is completely gone, the water evaporates very slowly, and what to dry in the sun depends on the wind, and today there is no wind, and this slurry is not dry.

So, she had to light another fire, take the mesh sieve and bake it slowly...... "It's almost...... "It's almost there" and looked at it carefully, feeling that it was not enough, "Wait a little longer......"

"Uh......" Looking at the gradually wrinkled results, Sima Pianpian secretly rolled his eyes, "Try again!" She got up and started a new round of action......

After repeating this many times, Sima Pianpian finally gained some valuable experience, and yes, she is making paper!

As soon as she saw a room of plant fibers, she thought of papermaking, and at first she just tried it, but she didn't expect that this rope vine was really a treasure and could really be done! Although the color of the paper is pale cyan, not pure white, it is enough for writing. The experience she gained was mainly about the heat, and it would get a smooth piece of paper when it was taken out at the right time, and it would become wrinkled if it was overheated, and she raised her eyebrows, which was not bad, and could be used as straw paper.

The children in the school now write with a kind of leaves, the ink is made of charcoal, and the pen is a wicker-like branch, which is usually used by primitive people to weave baskets and make toothbrushes, and now, brushing teeth with salt and bathing with pancreas has become the daily routine of primitive people. The making of the pen is similar to that of a toothbrush, dehydrating one end into a hair, and you can write with ink, and it is because of these simple writing tools that Sima Pianpian has not been in a hurry to make paper.

Moreover, she had to admit that because of the relationship between the system and the zài, she subconsciously did not pay attention to this matter......

However, from now on, it is still too late, she only needs to know that paper can be made zuò, and the rest will be handed over to the primitive people to use time to hone, now that the planting industry has developed, and the weather is cold, the gathering team should be idle......
