I am a primitive

Compared with Shitou, who likes to ask questions, he is lame without saying a word, which is reassuring to watch.

Looking at the stone that kept asking himself what to do with such a large piece of paper, what is the rendering... Han Cheng really wanted to tell the story of his neighbor who lived to be 90 years old and was still in good health.

But I was worried that it would discourage this guy's enthusiasm, so I had to endure this guy's hundred thousand whys and slowly tell him some related things.

After finally waiting for the large drying paper thing to be finished, Han Cheng stuffed it into the stone and urged him to make paper quickly. As for Han Cheng, he had already taken the opportunity to run away because he was overwhelmed by the disturbance.

He now completely understands why Sun Wukong was surrendered by Tang Seng.

Looking at Shenzi who was walking in a hurry, Shi Shi blinked his eyes a little aggrieved. He still had a lot of questions to ask, why did Shenzi leave?

Although I felt regretful in my heart, I still ran to make paper with the newly made things.

Shenzi just said a lot of things he hadn't heard before, which aroused Shi Shi's curiosity all at once.

So he wanted to make useful paper as soon as possible, and then went to see the Son of God to do new things.

If a craftsman wants to be good at his work, he must first sharpen his tools. After several years of practice, Han Cheng's drawing skills are not very good. If he wants to draw renderings that will amaze everyone in the tribe, he needs to use tools.

Han Cheng, who walked to the distance, quietly turned his head and saw that the stone had gone to the cave to make paper, so he turned back quietly.

After finding the lame, let the lame use tools to make a batch of rulers and compasses.

As for the right-angled triangle, this thing is relatively easy to make under the premise of compass.

If one diameter of the circle is used as the hypotenuse, and the other point is on the circle, no matter how they are connected, the result is a right triangle.

If you find two perpendicular diameters of the same circle, you can easily make an isosceles right triangle.

This kind of thing is hard for Han Cheng.

Holding a compass and ruler in hand, after drawing a few times on the paper, two different right triangles came out. As for using three wooden boards to compare the triangle he drew, it was lame.

After explaining the two things, paper and tools, Han Cheng had to do the rest by himself.

The next thing he was going to do was to get some paint out.

According to his painting skills, it is not enough to use charcoal alone. If he wants to impress the tribesmen enough, he must dye the painting.

This principle is the same as that of some chefs who are not very good at cooking and stick to spices.

As for the pigments, there is no need to worry about this. Although he is only a liberal arts student, red, yellow, and blue are the three primary colors of pigments. With these three pigments, he knows that all colors of pigments can be prepared in theory.

Don't worry about the cyan pigment, 'cyan is taken from blue and blue is blue, and ice water is colder than water. 'Not to mention the rest, just this ancient sentence has already revealed a method of obtaining cyan pigment.

People say that if you learn mathematics, physics and chemistry, you will not be afraid to travel all over the world. Facts have proved that learning ancient Chinese well is just as important.

At least while filling himself with chicken soup, up to now, Han Cheng has obtained the methods of three things from the ancient texts - version building, wheels, and green fuel.

As for the yellow paint, there is no need to worry about it, because there is a gardenia growing not too far from the tribe.

-------------Chapter Dividing Line---------------

Gardenia is a wonderful thing.

When the white gardenias are in bloom, their sweet smell can spread far and wide, comparable to sweet-scented osmanthus.

Moreover, compared to small osmanthus, large gardenias are more ornamental.

The gardenias that come out after the flowers bloom are very good for making tea.

Of course, for Han Cheng now, these are not the most important thing, the most important thing is that the gardenia color is very good.

Buckle two or three gardenias, throw them into the pot, and boil them with a little water to dye a pot of water yellow.

Two or three gardenias have such a big effect, if you put more, the color will become better.

Now the linen woven by the tribe has begun to be dyed one after another.

No longer only the taupe dyed with smelly mud, but also the yellow dyed with gardenia water.

It was not Han Cheng's idea to dye linen with gardenia water, but the grass in the tribe.

The reason is that when drinking gardenia tea, I accidentally sprinkled yellow water on the newly made solid-colored sackcloth, leaving spots of yellow at that time.

Everyone has a love of beauty, and the same is true for Qingcao. Wearing newly made linen clothes makes her very happy, and she even looks a little cautious when walking.

Now that the good clothes are soiled like this, it would be strange if I feel better.

Immediately, I hurried back to the house to take off my clothes and wash them with water.

The result was different from usual. After the yellow gardenia water fell on it, it seemed to have taken root. The green grass almost tore the clothes, and the yellow stained on it could not be washed away.

Not to mention Qingcao's sadness at that time, tears came out when she saw the clothes that were dirty when she just put them on.

Later, with an idea, I used more gardenias to boil water, then threw the clothes into the water and boiled them vigorously. As a result, a very beautiful color of clothes came out in the Qingque tribe.

As soon as this color came out, it immediately attracted many people in the tribe to follow suit.

For a time, the clothes in the tribe were all yellow.

This is often the case, bad things are not necessarily bad things, and at the same time, the discovery of many things is actually unintentional.

Nature is selfless, it is rich in things, and can provide people with many things they need, provided that you need to discover and use them.

Compared with later generations, the plants and animals of this era are undoubtedly extremely rich. Even the people of the Qingque tribe, under the leadership of Han Cheng, have created a large area of ​​cultivated land around the tribe. Nothing has changed.

Red paint falls on a vine.

The whole body of this vine is red. After peeling off the skin and soaking it in water, a basin of clear water will soon be dyed red.

Based on this characteristic, Han Chengcheng named this vine a red vine.

With the three plants of indigo, gardenia, and red vine, the three primary colors Han Cheng needed were also available.

The characteristics of these types of plants were discovered, and the latest ones were more than a year ago, so they are preserved in the tribe.

Even if spring has just arrived at this time, it doesn't matter if many vegetation have not sprouted.

Those stored before are enough for Han Cheng to use.

After going in and out for a while, three pottery pots were set up in the courtyard. Most of the pots were filled with water, and the water was soaked with red vine bark, gardenia, and indigo.

The flames under the clay pots are burning, and as the water temperature continues to rise, the colors contained in the three plants are quickly forced out and blended into the water.

Han Cheng was worried that the color was not enough, so he boiled it vigorously, and only stopped when the water was boiled to about a quarter.

I found a brush and paper, and daubed the boiled paint on the paper respectively. The color is not particularly correct, but it is enough.
