That night, the moonlight was as calm as water.

At this time, in the bedroom of the west courtyard of the Mu Mansion, Mu Ruyue was panting and sweating profusely. She wiped the sweat from her forehead, stared at the medicinal herbs on the table, and then smiled with satisfaction.

After several hours, she finally increased the age of all the herbs. However, using Qi to nourish the herbs did consume her physical strength. With her current strength, she could only increase the age of herbs that were fifty years old to one hundred years at best.

Any more and there won’t be enough energy.

"These fifty hundred-year-old herbs can be sold for money, and the rest can be used to refine pills."

As she spoke, she had already taken out the alchemy cauldron she had bought at the market today.

Now, what she wants to refine is a low-level human-grade rejuvenation powder, which is also the most common type of elixir.

Swish!

With a flick of her fingertips, a cluster of flames burned from her fingers. With a slight wave of her fingers, the flames leaped towards the alchemy cauldron and began to move.

The red firelight set off Mu Ruyue's fair face. Although she was still young, she had already revealed her stunning beauty at such a young age, even more beautiful than Mu Ting'er.

After all, this was Mu Ruyue's first time making medicine, so the flames dimmed in a short while, and the hundred-year-old medicinal materials in the alchemy furnace were wasted by her...

"Fail? Then try again!"

Mu Ruyue sneered. Ever since she could remember, she had never known what giving up was.

Swish!

The flames rose again and burned fiercely under the alchemy cauldron.

This time, with the experience of failure, I was able to control it more easily...

Mu Ruyue spent the entire night experiencing one failure after another. Next to her were piles of centuries-old medicinal herbs that had turned to ashes. Seeing this, Yan Jin couldn't help but twitch in pain.

Prodigal! This woman is clearly a prodigal!

Those were centuries-old medicinal herbs, not weeds. How could she waste them without any regret? It would be better for him to eat them and turn them into power.

It was not until the sky turned pale that Mu Ruyue successfully refined the rejuvenation powder.

She looked at the pill in her hand and frowned in dissatisfaction: "It took me a whole night to refine a low-level human-level pill. It seems that I still need to improve my alchemy skills."

If anyone heard what she said, they would really want to strangle this woman to death.

She learned how to prepare low-level human-grade elixirs in one night without any guidance. How can other alchemists survive if they need to spend three days and three nights to learn from a master?

Even the most outstanding alchemist in the history of the continent took two days to make the medicine for the first time.

Of course, the reason why Mu Ruyue could reach such a fast speed was closely related to her abnormal mental power and the fact that she had so many hundred-year-old medicinal herbs to waste. As we all know, the older the medicinal herbs are, the easier it would be for the alchemist to make the medicine.

"Girl," Yan Jin yawned and opened his hazy eyes, "Is it dawn so soon?"

"Yan Jin, I need to go to the herbal medicine shop."

Mu Ruyue tightly grasped the Rejuvenation Powder in her hand, her eyes flickering a few times. Last time, she only had a hundred-year-old medicinal herb, so naturally she didn't need to worry about it, but this time, she had to make sure that no one could recognize her.

The man is innocent unless he is in possession of a treasure. She had experienced this truth in her previous life.

In Fengcheng, on the bustling streets, the hawkers' shouts can be heard one after another, and occasionally a horse gallops by, bringing a noisy scene.

At this time, on the streets of Fengcheng, a thin girl wearing a bamboo hat walked into a popular herbal medicine shop and without saying a word, threw a package in front of the shopkeeper.

The shopkeeper was stunned for a moment, frowned and opened the package. After seeing what was in the package, he could no longer remain calm.

"This... is this a century-old medicinal herb? There are probably dozens of them here, right?"

Although century-old medicinal herbs are not as rare as thousand-year-old herbs, they are also very precious. What's more, there are fifty beads of century-old medicinal herbs here. Even though the shopkeeper has seen a lot of the world, he was still shocked by such a large amount of money.

“Miss, are you sure you want to sell these century-old medicinal herbs?” The shopkeeper swallowed hard and looked at Mu Ruyue in doubt.

Because the other party covered her face with a bamboo hat, the shopkeeper could only tell from her voice that the mysterious person in front of him was a young woman. Of course, to be able to sell so many medicinal herbs at once, this woman was at least not an ordinary citizen.

The latest novel is published first on Liu9shuba!

But what made the shopkeeper curious was how she got these fifty hundred-year-old herbs...

"Yes," Mu Ruyue nodded gently, her dark eyes calm and collected, "Besides that, there is also a pill of rejuvenation powder."

"Rejuvenation powder?"

The shopkeeper was stunned. Even though this Rejuvenating Powder was a low-level human-grade elixir, in this continent, alchemists were respected by many people. He naturally did not dare to underestimate anyone who could sell such an item.

"Miss, I can give you 100 gold coins for each of these 50 medicinal herbs. As for the Rejuvenation Powder, you need to find our Huichuntang's pharmacist to identify its quality. The price will be calculated based on the quality. If you trust Huichuntang, you can temporarily leave the Rejuvenation Powder with us and come back to get the money tomorrow. How do you do?"

Mu Ruyue glanced at the shopkeeper calmly, and after a long moment of contemplation, she said, "Huichuntang has a good reputation, so of course I trust it. In that case, I'll go there again tomorrow."

"Thank you very much, young lady."

The shopkeeper heaved a sigh of relief and ordered his subordinates to fetch the gold coins and personally hand them to Mu Ruyue. Mu Ruyue took the gold coins and left without staying...

"Hundred-year-old medicinal herbs. Haha. I didn't expect that there would be so many hundred-year-old medicinal herbs all of a sudden." The shopkeeper laughed and picked up a herb at random. However, at this moment, his smile suddenly froze. His eyes widened as if he had seen a ghost, his face full of surprise.

As if he couldn't believe his eyes, he hurriedly turned over the other herbs. Although it was not very obvious, there was a green sword-shaped mark of not too big or too small at the bottom of each herb.

"This... Aren't these the herbs from Huichuntang? But I know all the herbs in Huichuntang. It seems that there aren't so many hundred-year-old herbs, and they haven't been stolen before. So why are they in her hands? Oh, I remember a girl bought a hundred beads of fifty-year-old herbs not long ago. I picked them myself, so I remember them clearly. But how did the fifty-year-old herbs become hundred-year-old herbs?"

Yes, these were indeed the medicinal herbs he sold.

But what exactly happened?

"No, I want to go and ask to see Master Wu Yu. This is too unbelievable."

Fifty-year-old medicinal herbs turned into hundred-year-old medicinal herbs in just a few days. This must have shocked the shopkeeper? This matter must be reported to Master Wu Yu.
