After boiling for an hour or two, the water slowly boils down, and the pot is left with an amber sticky liquid, at which point the heat can be turned off, and when it cools, it will become more and more viscous, strained with fine linen and put into a short and fat open jar.

Because after all, the current linen cloth can't be woven much lighter and thinner, and it is more difficult to filter, Lu Qing didn't filter it too thoroughly, filtering out the most delicate part, leaving a bunch of "residues", which is also a good thing, and it's good to wash hands and wash things, because there are impurities in it, it's a little scrub, and there is no problem with taking a bath with rough skin, but it may be washed cleaner (funny face).

Except for Lu Qingqing, there is no one in the tribe who is not rough in skin.

She asked the pottery team to burn some small bottles, each with a capacity of about 30 milliliters, and put the fine and rough versions into the bottles, and gave one bottle to each of the fifty or sixty captains, and only one bottle of rough version was issued to the newly promoted ones as a benefit.

Here I want to say that in this rectification, the patrol team was officially established as the eighteenth team, and those good citizens who were transformed into slaves of the Dapeng tribe were officially turned into team members. The monitoring team expanded to ten teams, and the five teams of the horn continued to manage Qinglu City, and after Feng returned, he took back his original monitoring team from Lu Qingqing's hand, and the three people who followed him out, Chang, Yan, and Dong, were all upgraded to team leaders, and the same as the previous mountain, each person brought a team of monitoring teams, and Feng himself was the captain, and the mighty forty or fifty people went to Qingluyuan to preside over the construction work.

Lu Qingqing's two personal guards were also promoted to captains, and the four female warriors who went out with Ershi became her subordinates, and the original female patrol team picked another person to make up for the number, only the knife was still a single person.

Here are 30 captains, plus the growth team has been refined, there are several team leaders on the flax production line, the pottery group is also divided into the clay team, the pottery team, the pottery team, etc., the animal husbandry group is divided into cattle, sheep, chicken and other teams, the planting group is divided into soybean team, buckwheat team, flax team, sweet pole team, etc., and the construction component is more fine, divided into cement production team, paving team, transportation team and so on.

Between these squads, either one captain is in charge of two teams at the same time, or there are duplications among the team members, Lu Qingqing no longer manages them one by one, but promotes the original captain to the captain (in fact, it should be the team leader, but Lu Qingqing feels that it is not as good as calling the team leader, and it does not show the characteristics of a higher level in the position), let them manage the things in the group by themselves, and report on their work every week and month.

In this way, the total number of captains of seven or eight is not fifty or sixty. The freshly made acacia liquid is almost squandered.

The next day, the captains of all sizes brushed a degree whiter, and the fingers, nails, and black necks and behind the ears that had always been full of dirt became clean, although Lu Qingqing kept emphasizing that he should wash his hair more, but the hair that was always unwashed became fresh and clean.

A big step forward in the overall image improvement.

Then they excitedly reported back that the rough version was easy to use, comfortable and strong to rub, and the soft version was sticky like water, and it was not clean to wash.

Lu Qingqing: Hehe.

Although I dislike these rough people, but hygiene is a good thing, Lu lightly wants to provide this bath agent for a long time, even if he can't make money (points), it's fine, but the honey locust tree is just that, and the other arborvitae leaves and mulberry leaves that she knows can be used to wash her hair are not seen, Lu Qingqing has to start thinking about making soap.

In fact, it is not difficult to make soap, Lu Qingqing did not do it before, because of the lack of raw materials, one is enough oil, and the other is alkali.

Now that the tribe hunts and plants a lot, everyone can basically eat enough, and the water and leftovers in the body of the prey are generally not eaten, and Lu Qingqing did not let them be lost, but boiled them out of oil.

I've saved up a lot of oil for so long, and as for alkali, sodium hydroxide is not, but there is a lot of crude alkali, and it should be okay to be sloppy.

She added the oil to the alkalized alkaline water, and stirred it while heating it, because she was worried that the temperature would not be easy to control, so it was heated through water. And because the amount of alkaline water is difficult to master, it is difficult to make a paste if there is more, and it is impossible to make soap if it is less, and it is also very important to add water, so it is necessary to experiment slowly, which is not a simple process.

It took Lu lightly several days to try various proportions before finally getting a pot of slimy liquid, that is, soap.

This step is called saponification.

If it is an industrial soap, there is a salting out step, that is, adding salt water to the soap base to separate the soap components, but in that case, the glycerin in the soap base will also be separated, glycerin is the best moisturizer for the skin, without glycerin, the skin will be dry after the simple soap is used, and there is a feeling of tightness, so Lu gently omitted the salting out step.

Inject the soap base into the mold and let it cool, you can get a general white, but because the animal oil is not pure enough and the soap is grayish, it is better to leave the soap for a while to make it saponify fully so as not to hurt the skin.

Of course, a group of rough people in the tribe are probably not afraid of this.

What gave Lu a headache the most was that the smell of this animal was too strong, and the soap made of it didn't smell weird after washing?

She continued to experiment, adding some refreshing plant juice, or even juice, to the soap base to reconcile and mask the oily smell.

And because the color of the soap is not good-looking, Lu lightly wants to add some color, and now the tribe has used ore pigments, malachite, cinnabar and those ores are ground to extremely fine and fine, mixed with water to reconcile, it is the pigment, the most used is Lu Qingqing herself, and she used colored lines on the design drawings of the second city.

To this end, she also cut cow hair, wool and wild boar belly hair, and made a lot of brushes and brushes, which tossed the carpenters' team and the equipment team enough to choke.

But soap is used for bathing, so naturally mineral pigments cannot be used.

I thought that the linen cloth should also be dyed in the future, otherwise it would be like putting a sack on the primary color cloth all the time, and it would not look good.

She went out with her guards to find plants that could be used as dyes.

Green is everywhere, but not all grasses can be used as green dye, Lu gently searched the neighborhood, and chose several green plants with large leaves, strong sap color, abundant juice, and tried with the skin of several people, which will not be allergic or irritating.

Then there are all kinds of words, the flowers of different colors are collected separately, and they are brought back and processed separately.

Lu gently chopped or mashed the various plants he brought back, soaked them in water, mixed lime, and stirred them with heavy wooden sticks, and the clear and colorless water gradually became colored.
