Wang Lang only smiled faintly at Lin Huo's compliment, and said: "In fact, there are many animals in this world that are very useful to us, such as wolves that often roam near tribes in the grassland, if we can train them, the sensitive noses and ears of these animals can bring us a lot of convenience. ”

"Then when I go back, I'll tell Jianya that they're going to catch all these wolves." Fire said.

Wang Lang shook his head and said: "You didn't understand what I meant, I didn't ask you to catch those wolves immediately, that's not the point, I mean, animals are not just used to eat meat, some animals have been trained and can become my right-hand man, just like those horned dinosaurs we saw last time, if we have animals like this, then we can carry copper ore much faster, we have to pay attention to which animals are more docile and can help us." ”

People thought carefully about Wang Lang's words, and they all felt that they were very reasonable, and their minds kept recalling the animals they had seen, but their poor imagination and insight made them find nothing.

Kong Er looked at Wang Lang with a dejected face and said, "Chief, what if I can't think of any animals that are useful?" ”

Wang Lang smiled and said, "It doesn't matter if you can't think of it, I will tell you what kind of animals to pay attention to in the future." ”

Domesticating animals is not something that can be done in a day or two, and Wang Lang didn't want to continue the topic, so he said to the forest fire and the bark: "These things will be talked about later, after we collect salt in a few days, you two will take a raft back to the grassland." ”

The two of them nodded, although it was also a very interesting thing to capture that kind of giant deer, but compared to pretending to be forced in front of others, it was obviously the latter that attracted them more, and the bark even couldn't wait to see the surprised look of the strong teeth.

The next day, when the people were collecting salt, Wang Lang sat in the tribe and designed his first potter's wheel, and the pottery made by the clay strip plate construction method was very irregular in shape, and there was no way to make very thin pottery, and now the pottery made looks like a brick when broken.

With metal tools, Wang Lang had the idea of making potter's wheels, although he had never learned potter's wheels to make pottery before, but he had never eaten pork and never seen a pig run? In some TV shows and movies I have watched before, there are occasional scenes of pottery making, which is to put thin clay on a rotating disc and shape the shape of the pottery through the rotation of the disk.

The rotation device is very easy to make, and after Wang Lang simply drew the design drawing on the ground, he took the tools and started to make it.

Since he is not a professional carpenter, Wang Lang spent a day making a few planks and some rectangular wooden strips, and polishing them with a planer, after which the sun had set, Wang Lang stacked the finished parts under the built shed.

Three days later, Wang Lang finished making all the parts, called in others, and assembled the potter's wheel.

It took more than an hour to assemble the potter's wheel in the shape of a square table.

There are two side-by-side discs on the base of the potter's wheel, Wang Lang links them with tanned leather strips, Wang Lang shakes one of the discs, the simple belt transmission device starts to work, the rotation of the connecting rod makes a tooth-making squeaky sound, driving the disc on the table to pull the embryo to rotate constantly, the disc rotates very fast and very smoothly.

People looked at this miraculous scene with curiosity, three unrelated discs, just assembled together to turn like this, it seemed to them as if it was magic, but because of Wang Lang's previous warning, no one dared to associate all this with miracles.

Wang Lang turned vigorously for a while, and was very satisfied with the potter's wheel he made.

Kong Er looked left and right around this potter's wheel, but he didn't understand anything, and asked in front of Wang Lang, "Chief, why can this thing rotate?" ”

Wang Lang smiled and didn't explain, but said: "You need to think about this problem yourself, if you want to understand why he turned around, you have to think more and observe his operation process." ”

Kong Er couldn't get an answer from Wang Lang, which aroused his curiosity even more, and he kept watching around the potter's wheel, turning a few times from time to time.

Although many people were involved in the assembly of the potter's wheel, they did not know what it was used for, and people asked curiously, "Lang, what is this thing used for?" ”

Wang Lang patted the still rotating potter's wheel and said, "This is for pottery." ”

"This thing can also be made of pottery?"

People can hardly believe their ears that this weird big creature is actually used to make pottery.

Seeing the surprised look of the people, Wang Lang smiled, let people live a piece of mud, and brought a basin of water.

When the thing was ready, people gathered around the potter's wheel, full of curiosity to see how the thing was made.

Wang Lang placed the live mud on the potter's wheel, and asked Kong Er, who was still studying how the disc turned, to speed up the shaking.

With the rotation of the disc, the lump of mud was constantly pulled into a cylindrical shape on Wang Lang's hands, Wang Lang dipped his hands in water, and gently pressed his fingers on the top of the mud pillar, the moist and soft soil became thinner and thinner under the rapid rotation, and it didn't take long for a pot-bellied jar to appear in front of people.

Everyone's eyes widened in disbelief, and the round and smooth jar in front of them appeared in front of them, compared to this jar, the things made before were simply a pile of garbage, such a perfect thing was made so quickly, such an unbelievable thing, so that everyone was stunned.

Wang Lang asked Kong Er to stop turning, took down the drawn pottery embryo and put it in a cool place to dry, washed his hands, looked at the shocked people, and said with a smile: "You guys should try it too!" ”

Hearing Wang Lang's words, people cheered and rushed to try this magical thing with their own hands.

Wang Lang didn't expect that he could do so well by pulling the pottery embryo for the first time, he felt that he was still very talented in pottery making, but the fire that he tried next obviously did not have this talent, and the things he made were crooked, which made people unbearable to look at.

In the midst of people's laughter, the bark squeezed aside the embarrassed fire, and then crumpled the strange thing made by the fire, and confidently made Kong Er shake the disc, but what he made was on par with what Lin Huo made, and was despised by Lin Huo.

After a few attempts in a row, only Kong Yi and a woman were able to do it, and they obviously had no talent in pottery.

Kong Yi looked at the others triumphantly, he didn't have much sense of existence, but at this moment he finally found his own value, which made him very excited.

As the technique became more proficient, dozens of pottery vessels of various shapes were made, and after three days, the forest fire and bark left the tribe and rowed upstream on a raft full of supplies.
