I was a village chief in a primitive society

Chapter 449: Yeah! It's complicated. (4 more please customize)

"I need to use your hair."Coco said a little embarrassed.

Originally, she wanted to do an experiment, but because her hair was really too long, it even grew to the floor.

The tub couldn't fit in it at all, even if it could. It is difficult to clean, and it dries very slowly.

When the experiment failed, it caused trouble all over the body. When making hair washing products before, I always asked others to do the experiment.

Coco often went to the tribe to find Some girls with short hair came to experiment because their hair is relatively short and easy to wash.

"It turned out to be this, I thought something was wrong."Yu Ying nodded thoughtfully and immediately said:"Then use my hair."

Coco nodded, and asked the fox-eared lady to bend over and put her head into the wooden basin, letting the water completely soak her hair.

Then she used the light green thing to get a little water, rubbed it into foam, and then splashed it on the fox. On the ear girl’s pink hair.

The blonde girl waited until the foam was enough and then started to scratch it. She kept close to the scalp and started to scratch it.

"How about it? Is it strong enough?"Coco asked softly, fearing that she was too strong.

Yuying kept her eyes closed, and her soft voice sounded,"It's just right, the strength is very comfortable."

Fox-eared lady thinks this strength is too comfortable. It doesn't feel too good to have her hair soaked in water and her scalp being massaged. What's more, she hasn't washed her hair for two or three days, and she left the tribe to go to the hunting ground yesterday..

Staring at a lot of leaves, dust and other things on the head every day, it is inevitable that the scalp will be uncomfortable and a little itchy.

So when the blonde girl cleans the scalp, the feeling is very comfortable

"That's good."Coco continued to rub the fox-eared girl's head, making sure to clean it.

After ten minutes, she put away her hands, rinsed away the foam on the fox-eared girl's head with water, and wrapped her head with a clean animal skin. Hair, make sure not to let the pink hair get wet.

After wiping the hair for a while, wipe the other person's pink fox ears with the animal skin.

Because the ears will definitely get wet when washing the hair, and the ears will also be wet. It's furry and must be wiped.

The beast-eared girls didn't have this habit before. They just wiped their hair and tail every time after taking a bath.

But Su Bai told them not to do this, and their ears should also be wiped. The insides of the ears should also be wiped clean.

Because animal ears are different from human ears, they are both hairy, and the cochlea is relatively deep.

If not cleaned at that time, it is easy for bacteria to breed, which will cause some discomfort. Necessary disease

"How about it? Do you still feel comfortable after washing?"Coco asked with an expectant look.

Although the results of the previous experiments were considered successful, after all, this is the first time to experiment in front of a witch, so she is still a little nervous.

Yuying nodded without hesitation. Face said with satisfaction:"It's very comfortable. It feels completely different from washing my hair before."

At this moment, the fox-eared lady only felt that her scalp was very clean. Except for her pink hair and pink fox ears, she felt nothing else. It was as if her scalp had been given a real big cleaning. This kind of Don't feel too comfortable.

Before I washed my hair, I just rubbed it briefly, but no matter how clean I washed it, I always felt like there was something there.

"That's good."Coco breathed a sigh of relief, turned around and said,"Wu, this was also successful."

The smile on the blonde girl's face could no longer be suppressed, and the corners of her mouth began to rise slightly visible to the naked eye.

Su Bai saw everything in the scene just now, nodded with satisfaction and said:"I saw it, you did a good job. Are these two things difficult to make?"

It's one thing if something is successful, but it's another thing if the production process is simple.

If it's troublesome to make, takes a long time, or requires a lot of materials that are hard to find, then it's not that great. It is of great significance.

Because the things to be promoted should not be too complicated. Making things that are too complicated is a waste of time. It is okay not to promote such low-yield things.

After all, there is no money to be made by promoting these things. In this primitive era, there was no such thing. Money.

And he wants to promote this thing because he wants to make the tribe better. Of course, the premise is that it is not troublesome.

"It's not difficult to make, and you don't need a lot of things. It took a little longer because I had to experiment, but now I know exactly how to make it, and I can make many pieces in one day."Coco said with a smile.

The blond girl didn't know how happy she was to know that the things she made were useful to the tribe. In fact, making these things took a lot of energy and experimented with many things.

Coco was the first to make them. The experiment was plant ash, because it was marked on the information sheet she was looking at. Plant ash can be used as a stain remover because it contains potassium carbonate, which can remove dirt from clothes.

Of course, the words on the information sheet are all The words that Su Bai taught the blond girl were very simple.

Nowadays, the number and progress of literacy among girls in cement houses has greatly improved, and they can know some daily words. The second laundry soap studied by the blond girl is a mixture of plant ash and shell ash..

Shell ash contains calcium hydroxide. When mixed with plant ash, it can generate potassium hydroxide. When it is immersed in water to wash silk fabrics, it reacts chemically with the oil attached to the surface of the silk fabrics to form"potassium soap", which can wash the silk fabrics clean. Bright.

Although those linen clothes are not made of silk, the cleaning power is similar.

Next is saponin. You need to mix raw wheat flour with cold water and apply it thickly on the dirty areas. After it dries, rinse it with hot water. It became clean.

But this method is really troublesome, and hot water will cause damage to the linen, so this method was abandoned. The last method is to use saponins and bath beans, which is to pound the saponins to make In the shape of balls, soap locust can produce foam in water, which is why the blonde girl's piece of stuff can produce foam. There were still a lot of soap locust in the primitive era. You just need to look for it carefully, but you need to really find it. It'll take a while

"Since it is not difficult to make, you can produce more, and then we can use it first, and then give some to the chiefs, and then teach others after you are proficient."Su Bai said softly

"I get it, I'll keep experimenting and get better at it."Coco nodded heavily..........................................
