All night, Wei Xia and the others were abused to death by the strange smell of medicine, but in the end they all held on silently.

When it was almost dawn, they finally saw some results, and only then did several people believe that Wei Zhen was indeed making medicine.

There are many types of ointments, liquids, pills, etc., with different functions, and different smells and colors.

Almost every medicine was in large quantities, and all of them were properly placed in the crockpot, the empty jar that their father used to hold wine.

Of course, in addition to medicine, there are other rare things. For example, toothpaste and toothbrushes.

The toothbrush is made by Wei Xia, with a handle that is cut after roasting Nanzhu, with dozens of small holes in three rows at one end, and the treated manes are stacked one by one, and a toothbrush is completed.

It looks like a very simple thing, but it's really troublesome to make, not to mention that the material used to make the toothbrush is soaked and soaked in the liquid medicine.

It is said that such a toothbrush is waterproof and does not lint, and is tough and does not mold.

After making her first toothbrush, she couldn't wait to try it out.

The effect is really magical, after the delicate and soft brush is wet, it really does not stick together and fall into a piece, but stands up in a bunch.

After getting wet, I put it in my mouth and try brushing it back and forth, and even if I brush my gums, I don't feel any pain at all, and my teeth are cleaned.

Dip a toothpaste and then brush, a lot of bubbles can be made in a few moments, teeth and mouth become clean and refreshing at once, and the coolness of peppermint makes people feel more shocked and awake instantly.

Who would have thought that something that almost blinded his eyes when boiled would have such a fresh and refined effect on the finished product?!

Toothpaste and toothbrushes have given Wei Xia a very good experience.

"Wonderful!" Wei Xia exclaimed at Wei Zhen, his eyes changed from tired to shining, because he had discovered the business opportunity at the first time.

Such a delicate thing is very suitable for the use of rich and noble families, and it is unique to their family, and the price is not just happy to open it?

So after a night of unremitting efforts, Wei Xia used the only materials to make dozens of toothbrushes.

The toothpaste is made by Wei Dong, and he is very curious about the extraction and addition of medicines, which can change the color, change the ingredients, and change the form between the concoctions.

It is said that this is called a chemical reaction.

Zhao Yuan knew these names, and in their royal collection, the first emperor had a biography, but the details were not detailed.

The biographies left by the first emperor are more about military books and statecraft, as well as some simple mathematics, improved weapons and agricultural tools.

And Wei Zhen is better at chemical reagents, the kind that improves the efficacy and physical fitness, and the same is true in his previous life.

"Little sister, the toothpaste and toothbrush are very novel and chic, can we exchange it for money as a long-term business?

If there is a fixed income in the family, my father doesn't have to work so hard, he runs out all day long, eating and sleeping..."

Wei Zhen's sudden respect for her father is very obvious, and most people are looking at it.

Wei Dong used his father as a raft to prevent Wei Zhen from paying enough attention to it and leaking the recipe casually.

The key toothbrush and toothpaste technology is in his own hands, and the fourth child is not counted, he has to study and learn.

It is equivalent to that he has the first opportunity than the boss, with his father's connections and prestige, it is absolutely no problem to open the way, and when he makes a profit, the first person to benefit must be himself.

If you don't do it, it will become your own unique business in the end, so you don't have to work hard to farm.

In this way, the hard work of this night was not wasted.

Otherwise, next time he won't actively do things for Wei Zhen, and he will sleep beautifully with his mother-in-law like the boss, isn't it fragrant?!

"Yes, I'll write you how to make it."

Wei Zhen doesn't know how to do business, so she can only rely on the second child to toss by herself.

Wei Xia knew that this would be the result, fortunately he shot quickly, but he couldn't help but be excited.

As long as the boss sleeps, he doesn't have to follow his ass to farm in the future, right?! Getting rid of the title of the second oldest in 10,000 years is just around the corner.

Hey! Therefore, the mother-in-law should be like his daughter-in-law, with a chest as big as her breasts.

The kind of person who has no ability and high heart will only drag his feet, when who doesn't know the little bit of caution of the eldest daughter-in-law.

"Then be careful not to leak the recipe.

Now that you're pretty much packed, you each go freshen up, I'll make breakfast, and I'll catch up on sleep when I've eaten. ”

The second child is in a good mood and automatically takes over the rest of the work.

The finished medicine or the remaining materials have been put into storage, the unused waste materials are emptied, and the kitchen is washed again, and there is no longer such a big smell.

The places where the teeth are usually cleaned are replaced with toothbrushes and inserted in bamboo cups with their names engraved.

The toothpaste is placed in a long bamboo tube, with a gland on the top and a small closed outlet on the side, which is very convenient to squeeze out the appropriate amount of toothpaste after pressing it once.

The sealing of the bamboo tube is good, and the toothpaste is not easy to deteriorate, these tips are of course designed by Wei Zhen, but they are Wei Xia's hands.

Everyone saw that it was almost cleaned up, so they agreed with Wei Xia's words, picked up their freshly baked toothbrushes and toothpaste, and washed them.
