After Tong finished dancing, he dragged Bi Chen to the rented house, which was lent to them by Bai Zewei.

After all, the storefront is too much, Lin Zi also needs a place to live, and living in an inn is expensive and inexpensive, Bai Zewei lent them this yard, and she didn't refuse.

"Bi Chen, you help me control the wind, from now on, I am going to make dysentery pills, it takes four hours to purify the medicine, and there can be no interruption in between, so don't bother me during this period."

"You're going to make medicine? Okay, I'll take care of the wind! Bi Chen's face was excited, who didn't know that the dysentery pills in the Holy Medical Hall were hard to find, and they could save people's lives, and now the princess was finally willing to make medicine.

In Bichen's eyes, what kind of flower candy? What mooncakes? It's not as fast as this pill to make money.

She also knew what Tong Wu was worried about before? Just because the medicine of the Holy Medical Hall could not be surpassed and imitated, she was afraid that if she exposed her identity, she would drag King Xuan back.

Tong Wu had already brought the medicinal materials, and the experimental utensils had also been brought, and Tong Wu began to purify the medicine.

One of the most important things in dysentery pills is extracted from wormwood, which is extracted cold, which is very difficult and needs to be taken slowly.

However, the powder that comes out has a strong effect on the treatment of dysentery, and 20 grams of powder with other Chinese medicinal materials can make hundreds of pills, although it takes a long time, but it is a good investment.

Tong Wu worked hard, Bi Chen was guarding outside, and in the afternoon, Bai Zewei returned to the mutual market, knowing that Tong Wu was relieved here.

"Is she making medicine?" Bai Zewei asked worriedly.

Bi Chen looked at him vigilantly, then bared his teeth and said, "What do you do, what do you do?" Young Master Bai Zewei, the younger brother of Bai Zeyuan, the general of Zhenguo. ”

Bai Zewei glared at her, looked her up and down, and said, "Knowing my identity is amazing, why are you talking so sour?" Look at you, you're also a woman, why do you look like this? Ugly to the extreme! ”

"Bah, your eyes are lame, you can't see what beauty is? What is ugly, right? You think you're good-looking, ruffian, restless! Bi Chen retorted dissatisfiedly, and didn't want to look at Bai Zewei in a blink of an eye.

"You, you...... I can't tell the difference, I know what you are? Dizzy, Xuanyuan Yuchen didn't know how to choose a character like you to dance with, I think it's because you're ugly, so don't worry, I'm also stronger than you, at least I'm handsome......" Bai Zewei shouted angrily.

Yang Bichen stopped talking nonsense with him, went up and kicked him in the leg, kicked him and screamed, stretched out his fingers and didn't say a word.

In the house, Tong Wu is boiling medicine, this kind of boiling is more special, it belongs to the cold boiling system, that is, the water cannot be boiled, only more than 50 degrees can be boiled slowly, she does not dare to use firewood, because the firewood fire is too strong, she uses candles to boil medicine, and the fire is easy to control the temperature.

This time is more difficult, bored she went to wash up, from last night to now, she has not been aunted to wash her face and brush her teeth.

When it came to brushing her teeth, she sighed, this ancient salt is really difficult to use, and it feels very uncomfortable to put in the mouth, and the toothbrush here is made of willow branches tied together, and it is not good to use at all, and the inside of the mouth cannot be cleaned.

Tong Wu helplessly brushed his teeth while complaining about these items in his heart.

Suddenly, her eyes lit up, she looked back at the flame, according to her experience of making pills every time, this candle flame needed to be boiled for two hours, during this time she had nothing to do except stare at the fire, instead of wasting time here, it was better to try to make a new product, a product that would make herself comfortable and the people of the whole country comfortable.

Thinking of this, Tong Wu hurriedly washed up, then found cinnamon and honey, then added the flower sugar syrup and some salt he brought, and began to try to make toothpaste.

The first time it failed, the second time it was okay, the third time, it was already very successful, not only that, the taste was good, but it also had a cleaning effect, the only drawback was that the ancient materials did not produce foam, but it did work.

For example, this cinnamon honey toothpaste, when she was in modern times, a Korean classmate had given it to her, which was made by her mother herself, which not only can whiten her teeth, but also tastes good!

And I also told her how to make it, she tried it, and it was good.

As for this toothbrush? She can't do it, but if she finds a craftsman who makes the brush, she will be able to do it!

Seeing her product, Tong Wu laughed heartily, she found a bottle and put the honey toothpaste in the bottle.

Try it yourself for a period of time, if it's good, you will be ready to produce it in large quantities in the future, and she also thought of a product, which is necessary to make toothpaste, but the mutual market here has not seen that kind of material, and when she has time, look carefully, maybe she can find it.

Finally, after four hours, Tong Wu has made a batch of powder! A total of more than 20 grams, she carefully put them into bottles, then cleaned all the utensils, disinfected them with high wine, and packed them.

Tong Wu stretched his waist, turned his neck, and lowered his head for a long time to work in his cervical spine was a little uncomfortable.

She opened the door, Bai Zewei rushed over, he was holding a plate of braised elbows in his hand, and looked at her with a look of surprise, "Where are the pills?" Is it done? ”

Tong Wu shook his head, "I have to be busy again, this pill is not so simple to make!" ”

Bai Zewei took a deep breath, and then nodded heavily, "Yes, yes, I'm hungry, let's make dinner, let's eat!" ”

It's already dark, and Lin Zi has also closed the door and come back, he still complains that business is not good, and it seems that his tolerance is a little low.

The four of them sat at the dining table to eat, Bai Zewei prepared a table of delicious food, Bichen still had the old rule, and all the dishes had to be eaten first.

Because of this, the two quarreled again, and finally Bi Chen raised his fist, and after Bai Zewei cooperated with all of them, she allowed Tong to dance with chopsticks.

Lin Zi had never seen this kind of operation, and he hadn't seen her so worried when he and Bi Chen were eating here a few times ago, what's wrong with it now?

Although it was strange, he didn't ask about that, after all, he was in a very bad mood now, and the whole person was weak.

When everyone was halfway through eating, he finally couldn't help it, looked up at Tong Wu, and asked:

"Sister Dong, I'm really worried, although you are a major shareholder and have invested fifty-two taels of silver, we are all shareholders, but what if you really lose, what if you really lose, what about more than fifty taels of silver?"
