I thrived in the primitive tribe

Next, she placed the weeds she had brought back in a ceramic container and lit a fire to burn them.

The weeds gradually turned to ash under the licking flames, and she collected the ashes.

Add an appropriate amount of water and boil it down; soon you will get the desired alkali solution.

To ensure the purity of the lye solution, she filtered it multiple times, patiently removing impurities.

She then slowly poured the filtered alkaline solution into the prepared seashell powder and gently stirred it with a thin bamboo stick to ensure that the two were thoroughly mixed.

After filtering again, she set the mixture aside to settle overnight for use the next day.

After a busy day, Lu Yao looked up at the sky and realized that the sun had already set and it was getting late.

She cleaned and arranged all the utensils neatly, then waited expectantly for tomorrow to arrive.

The next morning, just as dawn was breaking, Lu Yao couldn't wait to get up and take out the liquid that had settled overnight.

She carefully took the clear alkaline water from the top and poured it into the prepared lard along with the fine salt.

As she continued to stir, the lard and lye water gradually blended together, undergoing a saponification reaction until it turned into a thick paste.

As the paste in her hand gradually took shape, a satisfied smile appeared on Lu Yao's face.

She carefully packed the homemade soap into the bamboo tube she had brought back the day before, pressing it down gently.

This is to ensure that the soap retains its shape during the setting process.

As the soap gradually cools and solidifies, it slowly takes shape inside the bamboo tube.

After the soap had completely set, Lu Yao eagerly took out a small knife and gently cut along the edge of the bamboo tube.

Cut the whole bar of soap into small, even pieces. After cutting...

She carefully placed the soap bars in a cool, well-ventilated place to allow them to continue saponifying.

During this process, the ingredients in the soap react further, making its texture finer and its fragrance richer.

Seeing that the soaps were finished and neatly arranged in the shade, Lu Yao felt a sense of accomplishment.

All that's left is to wait for them to fully mature before they can be put into use.

Lu Yao thought to herself, "Recently, the people of our tribe have been overjoyed because of the sugar cubes they made from sweet stalks, both adults and children."

Everyone loves these sweet snacks; plus, with the current availability of cold drinks and desserts, if teeth aren't cleaned regularly,

The tribespeople's teeth will eventually rot from eating sweets.

With these thoughts in mind, Lu Yao decided to also make toothpaste and toothbrushes for cleaning teeth.

"In the era before modern dentists and advanced medical equipment, the consequences of dental problems would have been unimaginable."

She recalled what she had read about toothpaste and toothbrushes and began preparing the materials.

She collected some herbs with cleansing and anti-inflammatory properties, intending to use them to make toothpaste.

At the same time, she also found some thin, soft twigs, intending to whittle them into the bristles of a toothbrush.

This time, Lu Yao asked her people to help her cut fresh bamboo. The bamboo was lush and green, carrying the unique fresh scent of bamboo.

Then, she carefully placed the fine salt from the tribe into the bamboo tube and pressed it down to make sure the tube was full.

To seal the bamboo tube, Lu Yao cleverly covered it with bamboo leaves and then tightly sealed the opening with moist mud.

Ensure that no impurities enter during the firing process.

Next, she gently placed the sealed bamboo tube into the fire, letting the roaring flames slowly engulf the outer wall of the bamboo tube.

Under the intense heat of the flames, the bamboo sap in the bamboo tubes begins to slowly seep out, quietly blending with the fine salt.

As the bamboo tube continues to be calcined at high temperatures, the organic matter inside is gradually decomposed, leaving only pure inorganic matter.

The originally tough fibers also become soft under high temperatures, making them more beneficial to human health.

During this process, the natural components in the bamboo sap permeate the salt, adding a unique freshness and nourishment to the toothpaste that is about to be made.

After the bamboo salt was fired, Lu Yao carefully took it out of the bamboo tube and gently placed it into the prepared ceramic jar.

She picked up a stone and patiently ground the bamboo salt until it became as fine as powder.

Next, Lu Yao took out the carefully selected medicinal herbs one by one and ground them into powder.

Afterward, she mixed the ground medicinal powder with bamboo salt, and then slowly added an appropriate amount of alkaline water.

Under Lu Yao's skillful hands, these ingredients gradually blended together to form a toothpaste that not only has cleaning functions but also contains anti-inflammatory ingredients.

After finishing the toothpaste, Lu Yao didn't stop, because she knew that a complete teeth cleaning tool also needed a toothbrush.

She turned around and took out a thin, soft branch that she had prepared beforehand.

She had specially selected these branches; their fibers were soft and elastic.

It can clean teeth without damaging the mouth, making it an ideal material for making toothbrushes.

Before starting, Lu Yao carefully inspected each branch to make sure they were free of cracks or insect damage.

Then, she peeled off the outer bark of the branch, revealing the clean, delicate wood inside.

This step is crucial because the outer layer can affect the toothbrush's softness and cleaning effectiveness.

Next, Lu Yao picked up a hard stone, placed one end of the branch on the flat stone, and began to pound it forcefully.

Each strike was accompanied by a slight vibration and scattering of the twig fibers.

With Lu Yao's patient pounding, the fibers of the branch gradually became loose and soft, forming a natural brush shape.

She carefully inspected every part of the toothbrush to ensure it was both soft and durable, and would work perfectly with the toothpaste.

When the last toothbrush was finished, Lu Yao smiled with satisfaction.

With the toothpaste and toothbrush already made, Lu Yao was filled with excitement and trepidation, eager to experience the fruits of her labor.

She carefully picked up the newly made toothbrush and gently dipped it into the homemade white paste in the ceramic jar filled with toothpaste.

The toothpaste contained several carefully selected herbs, giving it a faint, natural fragrance.

Then, she slowly brought the toothbrush to her lips, took a deep breath, and prepared for this unprecedented brushing experience.

The moment the toothbrush touches the tongue, a flavor that is both fragrant and slightly salty instantly spreads throughout the mouth.

Lu Yao savored the unique flavor, secretly delighted: it tasted much better than she had expected.

She started trying to brush her teeth, her movements a little clumsy.

Perhaps it's because I haven't brushed my teeth in a long time, and my mouth feels a little uncomfortable;

Or perhaps it's because homemade toothbrushes feel different from commercially available toothbrushes.

At first, she had difficulty controlling her strength and accidentally poked the inside of her mouth.

Fortunately, she chose a twig with very soft fibers; otherwise, her mouth would probably have been torn in several places.

Whenever this happens, Lu Yao has to stop, adjust her posture and intensity, and then continue.

However, as time went on, Lu Yao gradually mastered the skill of brushing her teeth, and the toothbrush became more and more comfortable in her hands.

She began to enjoy the process, feeling the toothbrush moving between her teeth, removing the dirt and food residue attached to the surface.

Finally, after spitting out the water in her mouth, Lu Yao couldn't wait to get close to the clear water.

She carefully observed her teeth in their reflection in the water, and saw that they shimmered with a healthy luster, which pleased her greatly.

Not only that, but there is also an indescribable refreshing feeling in the mouth, as if the entire oral cavity has been cleansed again.

Lu Yao couldn't help but wonder: Was it the added herbs that had such a magical effect, or was it the toothbrush that did it?

Perhaps both of these factors played a role?
