"I don't know. An Keyi shook his head weakly: "I had another idea before... In the medicinal solution you prepared, the effect of the Seven Star Grass is to enhance the final medicinal power of the medicine, but at the stage of adding the Seven Star Grass, if you add too much, it may also change the overall medicinal properties of the end, I have repeatedly studied many ancient books, and came to the conclusion that adding less Seven Star Grass should have a higher success rate. If you knew that you still failed, you simply added three more seven-star herbal liquids. ”

Lin Xi's eyes flashed, and he looked at An Keyi and immediately asked, "So, if there is a chance to start all over again, then you can add three more seven-star grass to give it a try?" Maybe there is still some chance of success?"

He didn't want to know too much about esoteric pharmacology, and he couldn't understand it all, he just wanted to know what else he could do if he had to do it again.

"What else can I do?" An Keyi didn't understand Lin Xi's thoughts at all, he was a little distracted, and his voice lowered: "If I can't study more things in the next four years, this is the only way to try again." ”

Lin Xi took a deep breath, put the crystal drop bottle with the "Seven Star Grass Liquid" sticky note in his hand, looked at the light layer of turquoise liquid inside, looked at An Keyi seriously again and asked, "Teacher, listen to what you mean, this Seven Star Grass Liquid shouldn't be just an adjuvant medicine, not the two main medicines?"

"The Seven Star Grass Liquid is precious but not rare, although it is very valuable, it is not difficult for the academy to obtain. What is really scarce is my own blend of thyme and spirit baby ginseng medicinal liquid. Because of his personality, although his chest was empty and he didn't even want to speak, when he heard Lin Xi ask seriously, An Keyi still answered.

Lin Xi looked at her and said, "Since you trust me so much, let's do it all over again." ”

"What did you say?" An Keyi raised her head in amazement, and her heart was even more nervous, if Lin Xi was also too disappointed and talked nonsense, then she really didn't know what to do.

"I said let's do it all over again. Lin Xi looked at her very firmly, repeated, and said, "Whether it can succeed or not depends on whether it is useful for you to add an extra three-star seven-star herbal liquid, but I can at least help you try again." ”

"What's wrong with you, what nonsense are you talking about?" An Keyi was completely flustered, and subconsciously grabbed Lin Xi's wrist, but Lin Xi's body temperature and pulse were very stable, and there was nothing abnormal at all.

Feeling An Keyi's soft fingers on her wrist, looking at her panicked appearance, Lin Xi couldn't help laughing: "Teacher, I'm fine... Also, I know that your knife is so soft that it can be rolled around your arm all the time, and I also know that you have a small red birthmark on your arm. ”

"How do you know, it's not a birthmark" An Keyi's eyes widened suddenly, and he suddenly reacted again, and exclaimed in disbelief: "Lin Xi, when... They actually peeked at me."

"No, I see it openly, but you don't know. Lin Xi smiled, and after saying this, the look on his face became serious, looked at An Keyi, and said softly: "Go back!"

In the instant change of the scenery that he had long been accustomed to, everything returned to the ten minutes before Lin Xi was familiar.

He had just walked into the pharmacy and had just sat across from Encore talking to her.

"Teacher, cultivators' soul pills, can other cultivators use them?" Because he already knew a lot of things, Lin Xi could ask some different questions this time.

"No... After this soul pill leaves the body, it will soon disperse its soul power and become something similar to a bone stone, so this kind of soul pill with soul power retained... Especially the Soul Pill in Purgatory Mountain is still very rare, if you can't make it back in a few days, then I really have to ask someone else for help. ”

"Then there should be very few people who have cultivated to this level of national soldier in the border army, right?"

"A national soldier is a real national soldier... Of course, there are very few, and it is generally used to spy on the enemy and carry out some plundering in the small army, and the presence of a soul master is already good. ”

......

At the end of the conversation, the pharmacy fell silent, and An Keyi and Lin Xi began to seriously dispense the potion at the same time.

Because he trusted Lin Xi very much, and his sense of time was not as accurate as Lin Xi's, he had to always pay attention to the large and small hourglasses used to calculate time beside him, so An Keyi's spirit was all focused on the medicinal liquid he had concocted, and he didn't notice at all that in the first two minutes, when she mixed the three medicinal liquids and added the fourth medicinal liquid, the Seven Star Herb Liquid, Lin Xi did not follow what she had before, but added nine more drops of the Seven Star Herbal Liquid to it.

The liquid medicine of the two was still very tacitly completed at the same time, and it was all handed over to Lin Xi, it was still a bottle of dark red liquid medicine mixed with dark cyan liquid medicine, under Lin Xi's constant shaking vigorously, two minutes later, the two liquid medicine completely reacted, completely fused, and still turned into a transparent and melted dark blue gel-like substance, from the appearance, compared with the last time, there was no abnormality at all.

Because he knew the result of the last time, Lin Xi was more nervous this time than the last time. After taking a deep breath, Lin Xi opened the glass medicine bottle that sealed the purgatory mountain powerhouse's qi and blood and soul pill, and dropped three drops of the dark blue liquid that was configured this time into it.

"Whew!"

Unexpectedly, a puff of green smoke rushed out of the mouth of the glass medicine bottle.

However, what made Lin Xi's eyes widen for a moment, and his breathing couldn't help but stop for a while, this time the black blood in the glass medicine bottle was almost completely boiling, and the moment the three drops of the medicine liquid spread, all the black blood in the entire medicine bottle turned bright red!

An Keyi was instantly quiet.

Only this time her lips trembled slightly, but there was an irrepressible bright red on her face.

An Keyi's expression gave Lin Xi the answer, looking at the smoke dissipating from the mouth of the bottle, looking at the bright red that was completely transformed in the glass medicine bottle, Lin Xi was excited in his heart, and couldn't help but sigh sincerely: "The pharmacology in this world is really very profound..."

After being quiet for a long time, An Keyi stood up and bowed to Lin Xi seriously: "Thank you." ”

This suddenly made Lin Xi a little at a loss, and the tutor in Lulin Town in the past few years suddenly made him consciously return the gift.

"Thank you... I have finally lived up to the sages of the academy and those who shed their blood for the study of this subject. And An Keyi's next sentence made Lin Xi even more solemn.

Obviously, Encore is not the only one who has paid a lot for this subject.

Fortunately, the project was successful.

"Although Vice Dean Xia said that this bottle of liquid medicine is a reward for you, and he doesn't have his reason, this bottle of liquid medicine is very precious, don't waste it when you use it in the future. After being quiet for a few more minutes, An Keyi looked at Lin Xi and said, "Judging from the medicinal power of Fang Cai, it should be effective as long as a thin layer is applied to the blade, and some medicinal power can penetrate into the opponent's skin." ”

"But I don't know if there is any way to make up for it after eliminating the medicinal power accumulated in the bodies of these masters in Purgatory Mountain and using it for demonic transformation. After Lin Xi nodded and put away the crystal drop bottle, An Keyi added: "After all, Purgatory Mountain is the same as other cultivation places, and there are some secrets that we can't know, so it's best to use it after the Purgatory Mountain cultivator who has really turned into an enemy demon." And it's better to use it once you don't leave it alive... Remember, this is a secret for our Qingluan Academy. ”

"Students understand. Lin Xi thought in his heart that he had dropped more of those seven-star herbal liquids, and he was afraid that he would not be able to explain it at the moment, and after thinking about it, he looked at An Keyi and said, "Teacher, although this prescription has been researched now, the materials are rare... I'm afraid it will take a few more years to get the materials together?"

At this moment, it was a complete success, and after An Keyi was excited, he regained his usual temperament, and said calmly: "Yes, it should be three or four years at the earliest, and in the past three or four years, the main task of some lecturers in our Imperial Medicine Department should be to try to find and cultivate a few of the main medicines... However, it should take a few years, and after a few years, it may be possible to refine a lot of this kind of liquid. ”

Thinking that since it was determined that it would be a few years later, there was no need to be too anxious, Lin Xi smiled slightly in his heart, but looked at An Keyi with an extremely serious face: "The student has a request, I don't know if the teacher can agree." ”

An Keyi frowned slightly, thinking that you should not take the opportunity to make some greedy requests, otherwise my opinion of you will definitely change greatly, but what made her slightly stunned was that Lin Xi said: "This is extremely meaningful to me, and I also have experience, so the next time I want to refine this medicinal liquid, I still want to ask the teacher to refine it with me." ”

"It's fine. An Keyi pondered slightly, and said: "Even if the medicinal materials can be successfully cultivated in the future, this medicinal liquid can be refined more, and the prescription is always a secret of the academy, so it is naturally best for you and me to refine it." I have the right to promise you that. ”

Looking at An Keyi's current appearance, and then thinking of An Keyi's sad appearance, Lin Xi's heart was bright, and he smiled slightly: "That student thanked the teacher first." Since this liquid is up to me, do you want me to give some to the teacher first?"

An Keyi thought about it seriously and shook his head: "I don't have many opportunities to get out of Qingluan Academy... This liquid was originally intended for students who went out to practice and perform tasks, that is, to be used in times of danger... But after all, it's still in the secrecy stage, so even if you go out in the future, when you encounter danger, if your companions want to use it, you still have to hide it. ”

Lin Xi thought about it and nodded.

An Keyi also nodded, still saying in a book-like tone:

"It takes a lot of time for you to practice... I'm done here, so you don't have to come from tomorrow. ”

"I'll report the success later, you can get two credits as soon as you go out, this time I suggest you exchange for the Soul Gathering Pill, it should be able to help you improve your cultivation a lot." ”

"In the future, if you don't understand anything about the redemption of award credits and pharmacology, you can also come and ask me directly... Also, if I get a new research subject and need your help, would you be interested in helping me again?"

Hearing the first sentence, Lin Xi felt a little faintly lost in his heart, but when he heard the next two sentences, Lin Xi was suddenly full of joy, and his face was full of bright smiles: "Of course I'm interested." ”

(Last night, the blue sea was still asking me if I would add more to the bachelor, because the sea was not far from the bachelor.) I'll let the "sea" Grace, because I did write this book more slowly, more finely, and as a father, and over 30 years old, a lot of responsibilities have to be born, Children's Day with my daughter to play in the sand and the like have to consume some manuscripts, in order to maintain stable updates, I pay too much for books and book friends, and I have paid too little for my family and friends around me before, many times when I sleep I am thinking, what will I compensate for writing books in the future, when my classmates come to Wuxi, I can only spare a day to entertain, in order to write books, I even missed ten years of college reunions。 When my college classmates, our dorm mates, took turns calling me, I really wanted to cry. However, because I give more, I have to write better, so I would rather make less money, but also write what I want to write, and strive to make great progress in each book. In this life, there are many regrets, but what is pursued is nothing more than a clear conscience and inner peace. I've always loved fantasies, thinking that if I was in ancient times, I became a chivalrous man, walking in the bamboo forest in the night rain, and it was enough to have one or two confidants in my happy life, and now there are so many book friends who can understand and support me, so I am very at ease, and I am working hard to tell the story calmly, and strive to do my best. Originally, I said to the sea, slow down to reward the bachelor, and then let me accumulate more and revise the manuscript more, but when I got up in the morning and saw that Fang Lianhai suddenly won the bachelor's degree, I thought that I finally had to work hard, but I was still very moved. So today is destined to add more than one more. For Fang Lianhai, for the sea, for the sun, for the, wood,, red moon, etc., Kewen, Jazz, Miao Miao, etc. have always wanted to make a list of all the people I want to thank, as well as every book friend who cheers for me, because even 100 vertical and horizontal coins are also recognition and encouragement to me, I love you book lovers who are worthy of love, I like to communicate with you, but it also takes time, And what I lack now is time, and I think there must be a sunny afternoon in the future, where everyone gathers to have a happy and quiet chat. Finally, thank you again for your support, I can't repay it, I continue to meditate and work hard to code words)
