"Give thirty taels of silver to the kitchen. The people in the kitchen did a great job today. Without their help, we wouldn't have been able to catch these little bastards."

"This thirty taels of silver can be considered as a reward for them. They don't have to be so happy. Such things may happen again in the future. Just let them do their job well."

After hearing Qian Ruoyu say this, Yan'er nodded quickly.

After Yan'er left, Qian Ruoyu walked towards Yueya Pavilion alone.

Qian Ruoyu was thinking about one thing along the way, that is, how could he give the old lady the elixir of longevity?

After all, he had already made a big promise in front of Li Zhiyi, and he also took back the five hundred taels of silver. This longevity elixir must be given out no matter what!

This so-called longevity is nothing more than a tonic. Naturally, there is no medicine that can really extend a person's life.

But it can maintain the body, restore the body to a healthy state, and make people feel younger.

This is the real benefit of prolonging life.

After thinking about this, Qian Ruoyu just returned to Yueya Pavilion and went straight into his laboratory.

She wanted to try to combine Chinese and Western methods by boiling some suitable Chinese medicinal materials to see if she could really create a longevity elixir.

In this day and age, if a pill that can prolong life could really be created, it would probably be worth much more than the price of silver!

After all, this thing can really make people feel younger, and the effect is fully reflected in the body and mood. In this era, the thing that many people have the most is money.

Especially the circle in the capital where Qian Ruoyu is located. Although ancient people did not have this concept, perhaps some people in this circle would pay more attention to body maintenance.

Therefore, Qian Ruoyu took some tonic products and came to the center of the laboratory.

The middle of the laboratory has expanded to twice its size before, and there is a space for a white titanium table.

On the titanium table are placed some traditional Chinese medicine instruments made of alloys.

These include a Chinese medicine crusher, a vacuum storage box, several medicine grinders, and so on.

It looks like it was tailor-made for Qian Ruoyu!

Qian Ruoyu directly placed all the herbs he had taken from the medicine room on the table, and then began to study them one by one.

In Qian Ruoyu's mind, a large number of Chinese medicinal herbs and their functions began to gradually emerge. Although Qian Ruoyu closed his eyes, he blindly grabbed some herbs in front of him.

Put some of the medicinal materials into the grinder and grind them into powder.

As for the other part of the precious medicinal materials, Qian Ruoyu used a medicine grinder to grind them into large particles bit by bit.

Qian Ruoyu then mixed the medicine powder and large particles together thoroughly. This thing was already equivalent to a solid nutrient solution, but it was still missing some necessary ingredients.

Qian Ruoyu brought in some medicinal herbs from the medicine room, and also brought in some Western medicine elements.

Then use a small pot to slowly boil these medicinal materials.

Qian Ruoyu had no idea how long the whole process lasted. She opened her eyes from time to time to see if Yan'er had returned to Yueya Pavilion.

Yan'er had indeed returned to Yueya Pavilion, but she did not enter the room quickly. Instead, she reported to Qian Ruoyu in the yard and continued to weed and water the flowers in the yard.

Yan'er has a lot of time every day, but she is basically busy, for example, weeding and watering flowers, bringing herself meals from the kitchen, and tidying up the entire yard.

Qian Ruoyu could see how hard Yan'er worked. If it weren't for Yan'er's hard work taking care of Yueya Pavilion, it would probably be covered in dust and dirt everywhere.

Rather than being his maid, Yan'er is more like a considerate and caring nanny.

After thinking about this, Qian Ruoyu felt that perhaps he needed to reward Yan'er well and let Yan'er know that it was a great honor to be with him.

Qian Ruoyu returned to the medicinal material laboratory again and saw that the medicinal powder had been boiled into a paste, so he poured it into the molding machine.

After a few minutes of shaping, a pill about one centimeter in diameter gradually emerged.

After a period of drying, a complete pill finally appeared in front of Qian Ruoyu.

But this pill is not gray-brown or black, but rather a moon-white color!

The moon-white pill looked particularly bright in Qian Ruoyu's hand, like an opaque pearl.

But Qian Ruoyu knew very well in his heart that this pill did not yet have the full effect of prolonging life, because it still needed to be analyzed on pharmacology, and he had to taste the medicine himself!

After a whole afternoon, a brand new moon-white pill appeared in front of Qian Ruoyu.

Although it only took one afternoon, the longevity pill in Qian Ruoyu's hand already had initial effects.

Qian Ruoyu not only personally practices Tibetan medicine, but also analyzes its pharmacology. It is indeed effective in resisting cell aging in the human body, and this effect is extremely significant.

Although the efficacy will gradually decrease, you only need to take one pill a year to maintain a slightly better appearance and figure than normal people. But for Qian Ruoyu, this is enough!

The immediate effect is more convincing to others.

Qian Ruoyu opened her eyes, and the moon-white pill appeared in her hand.

In front of Qian Ruoyu, Yan'er had already arranged four dishes, one soup, two desserts and two fruits.

"You've been sitting here all afternoon, why don't you eat something? Aren't you hungry at all?"

But Qian Ruoyu smiled and said to Yan'er.

"Of course I'm hungry, but now hurry up and find a small wooden box. The smaller the better, but it has to look as expensive as possible!"

"We should have this thing here, right?"

After hearing Qian Ruoyu say this, Yan'er frowned slightly, thought about it, and then nodded immediately.

Yan'er went to the dressing table and soon found a small wooden box from the corner of the dressing table.

"Your Majesty, I heard that this box was used to hold pearls that were offered as tribute... It looks like it should be very precious, but the pearls have already been offered as tribute, so you kept the box for yourself. How about you try it?"

Qian Ruoyu naturally took the box quickly, and then put the longevity pill in his hand into it. It fit perfectly inside the box!
