After about two cups of tea, Ye Feiyan asked Chang Yue to stop stirring, and she picked up the stirring chopsticks, picked up the medicinal soup, and observed the shape of the medicinal soup flowing downward after the chopsticks were brought up.

When the chopsticks are about a foot high from the soup, the flow line formed by the soup brought up under the chopsticks is just a line between the chopsticks and the soup.

Ye Feiyan nodded in satisfaction and asked Chang Yue to take the medicine jar off the stove.

Ye Feiyan didn't care to explain to Gu Shaoyuan, Jun Lan, and Gu Yifeng, but took the remaining half-tube of potions and walked to the second room on the left side, repeating the operation just now.

It was time for two more teas, and Ye Feiyan finally finished the preparation of the second pot of medicinal soup.

Gu Yifeng finally couldn't hold back the curiosity in his heart, and asked out loud: "Little girl, why does this extracted potion not only make the medicinal soup thicker, but also change the color of the medicinal soup?" ”

Gu Shaoyuan's eyes flashed, he looked at Gu Yifeng, and couldn't help but have doubts about their identity.

However, because of the stronger curiosity in my heart, I had to suppress the doubts in my heart.

"Grandpa, there is a special ingredient in this potion, if you simply mix this medicinal material with other medicinal materials, this special ingredient will be emitted with the vapor mist, and now I have mixed this special ingredient into the medicinal soup that has been boiled, thus promoting the fusion of various medicinal ingredients in the medicinal soup, and in the process of fusion, their original color will change."

Gu Yifeng and Gu Shaoyuan both seemed to understand whether they understood or not, but they both clearly knew that the medicinal soup that became thick was easier to refine into pills, which meant that the addition of the medicine accelerated the speed of refining pills.

As for whether it enhanced the efficacy of the medicine, they couldn't know, but looking at Ye Feiyan's confident gaze, they felt that there must be nothing wrong.

"Miss Ling, Gu would like to ask, for different prescriptions, do you need to extract medicines from different medicinal materials in order to achieve the efficacy of the corresponding prescriptions?"

Ye Feiyan smiled, "The medicinal herb for extracting the potion is best one of the medicinal materials in the formula, so that the herb can not only exert its own medicinal effect, but also play a role in promoting the efficacy of other medicinal materials." ”

Ye Feiyan answered Gu Shaoyuan's question while motioning for Chang Yue to bring the medicinal soup to the two rooms where Chang Feng, Lan Jiang and the others made the medicinal soup.

"If all the herbs in the prescription do not produce a vapor mist with special effects when boiled, then you can find a herb that can match them to extract the herb, so that the extracted herb can only promote the effect of other herbs in the prescription."

After Chang Yue led someone to bring away the two jars of medicinal soup, Ye Feiyan walked out behind Chang Yue, but the explanation in her mouth did not stop.

"However, there is a certain degree of difficulty in the selection of such medicinal materials, if the selection is not appropriate, it will even produce side effects, reducing the efficacy of the prescription is a trivial matter, and the most afraid is that it will have the opposite effect."

Several people sat in the middle room again, Ye Feiyan glanced at the hourglass on the table, and continued: "Therefore, first of all, we must be familiar with the efficacy and possible side effects of various medicinal materials, and conduct experimental measurements on the components that may produce vapor spray, and make sure that they can be used before adding medicines. ”

Gu Shaoyuan couldn't help but be surprised in his heart, the seemingly extremely simple process, in fact, the work to be done in the early stage was not simple.

Gu Shaoyuan silently thought about the smell of the medicinal soup he smelled just now, and had a new question in his heart, "Miss Ling, I wonder if you can tell Gu what the effect of the pill you want to refine today is?" ”

Gu Yifeng squinted at Gu Shaoyuan, "Boy, you asked a bit too many questions. ”

sp; Jun Lan looked cold, glanced at Ye Feiyan, and then looked at Gu Shaoyuan coldly, "Little sister only promised you to see the process of refining our pills, but did not promise to tell you the efficacy of the pills. ”

Seeing Gu Yifeng and Jun Lan who were so nervous, the corners of Ye Feiyan's mouth couldn't help twitching.

To tell the truth, even if he told Gu Shaoyuan about the efficacy of the elixir, he would definitely not be able to refine it, because the distillation and extraction elixir, the addition of the elixir, and the agitation after the addition, as well as the control of viscosity and color all need to be grasped very well, and any small mistake may greatly reduce the efficacy of the elixir.

Gu Shaoyuan smiled at Gu Yifeng and Jun Lan in embarrassment, "I'm sorry, Gu Mou is indeed overstepping, but Gu Mou is too curious." ”

Gu Shaoyuan paused in his tone, and looked at Ye Feiyan with a sincere face, "I have seen and smelled the medicinal soup prepared by Miss Ling just now, and I have smelled the smell from the medicinal soup that is being boiled on the right side. ”

Ye Feiyan smiled and nodded, "It seems that Gu Gongzi has a deep attainment in medical skills, and he can distinguish the medicinal materials I use from the smell alone." ”

Gu Shaoyuan felt that his heart was inexplicably a little excited, and his face was flushed with a faint red, as if he was embarrassed.

"Miss Ling praised it falsely, Gu Mou has followed his grandfather since he was a child, although he has not tasted all kinds of herbs, but he has also tasted and smelled many kinds of medicinal materials, so he is very familiar with their smell."

Ye Feiyan shook Jun Lan's arm soothingly, smiled at him, and smiled at Gu Yifeng again, and only after the expressions on the faces of the two of them relaxed, did she continue to say to Gu Shaoyuan: "Looking at Gu Gongzi's figure, he should also be a martial arts practitioner, I don't know if you would mind asking my grandfather to test your internal strength cultivation for you?" ”

Gu Shaoyuan's expression froze, and a tangle flashed in his eyes, but after a moment, he smiled and stretched out his right hand towards Gu Yifeng.

He couldn't tell why, but he couldn't doubt the 'ordinary' looking Ye Feiyan in front of him, and always felt that this test would be beneficial and harmless to him.

Gu Yifeng was extremely reluctant, "Little girl, you don't plan to let this kid take your pill, right?" ”

Ye Feiyan smiled sweetly at Gu Yifeng, "Grandpa, I just started trying to refine this kind of elixir, what is the effect of the medicine, only more people can know it, right?" ”

After speaking, Ye Feiyan did not forget to wink mischievously and slyly at Gu Yifeng.

Gu Yifeng reluctantly stretched out his hand and put Gu Shaoyuan's hand together, "Count you lucky boy to meet a little girl." ”

Jun Lan's heart rose inexplicably sour, "Yan'er, have you thought about doing this?" ”

Ye Feiyan held Junlan's hand and squeezed it gently, "Big brother, you have to believe Yan'er, I will not be wrong to do this." ”

Seeing Jun Lan and Ye Feiyan's hands tightly clasping, Gu Shaoyuan suddenly felt very dazzling, and there was an urge in his heart to quickly separate them.

"Boy, be attentive, I don't easily measure the internal strength of others."

Gu Yifeng, who felt Gu Shaoyuan's abnormality, shouted loudly, instantly pulling Gu Shaoyuan's thoughts back.

Gu Shaoyuan tugged at the corners of his mouth and gathered his mind.

What was he just thinking? The two of them are brother and sister, and shaking hands is a normal thing, but what about when she kissed his face? This can only show that this brother loves this sister very much.

Poor Gu Shaoyuan didn't realize why he cared so much about the relationship between the two of them.
