"I don't know." An Keyi shook his head feebly: "I had another idea before... In the medicinal solution you prepared, the function of Seven Star Grass is to enhance the final potency of the medicinal solution, but adding Seven Star Grass

At that stage, if you add too much, it may change the final overall medicinal properties. I have repeatedly studied many ancient books and came to the conclusion that adding less Qixingcao should have a higher success rate. If I had known it would still fail, I would simply add 30% more

Seven Star Herbal Liquid."

Lin Xi's eyes flashed brightly, and she looked at An Keyi and asked immediately: "So, if there is a chance to start over again, then you can try adding 30% more Seven-Star Grass? Maybe there is still some chance of success?"

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

"What else can be done?" An Keyi didn't understand Lin Xi's thoughts at all. He was a little lost and his voice lowered: "If I can't research anything more in the next four years, this is the only way I can try again.

"

Lin Xi took a deep breath, put the crystal dropper bottle with the note "Seven Star Grass Liquid" in her hand, and saw that only a shallow layer of turquoise liquid was used inside. She looked at An Keyi seriously again and asked

: "Teacher, listening to what you just said, this Seven-Star Grass Liquid should not be just an auxiliary medicine, not the two main medicines? That's why there is so much leftover?"

"Seven-star grass liquid is rare but not rare. Although it is very expensive, it is not difficult for the academy to obtain. What is really rare is the thyme and Lingying ginseng liquid that I prepared myself." Because of his personality, although his chest was empty, even

He didn't want to speak, but when Lin Xi asked seriously, An Keyi still answered.

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

"What did you say?" An Keyi raised her head in astonishment, feeling even more nervous. If Lin Xi was too disappointed and went crazy and talked nonsense, then she really didn't know what to do.

"I said let's try it again." Lin Xi looked at her very firmly, repeated, and said: "Whether it can succeed or not depends on whether the extra 30% of the seven-star herbal solution you added is of any use, but I can at least help you try again.

once."

"What's wrong with you? What nonsense are you talking about?" An Keyi became completely panicked and subconsciously grabbed Lin Xi's wrist. However, 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 look, Lin Xi couldn't help but laugh: "Teacher, I'm fine... Also, actually I know what you're doing

The knife is very soft and can be rolled around your arm, and I also know that you have a small red birthmark on your arm."

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

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

"

In the instant change of scenery that she had long been accustomed to, everything returned to what Lin Xi was familiar with ten minutes ago.

He had just entered the pharmacy and was sitting opposite An Keyi, talking to her.

"Teacher, can other practitioners use the soul elixir of a practitioner?" Because she already knew a lot of things, Lin Xi could ask different questions this time.

"No... after this soul pill leaves the body, its soul power will soon dissipate and become something like bone and stone. Therefore, this kind of soul pill with retained soul power... especially the soul pill in Purgatory Mountain is still very rare. If

If you can't come back within a few days, then I really have to find someone else for help."

"Then there should be very few people in the border army who have reached this level of cultivation, right?"

"A national warrior is a real national warrior... Of course there are very few of them. Generally, it is good to have a soul master in a small army that is used to spy on the enemy and carry out some plunder."

…

After the conversation ended, the medicine room fell into silence, and An Keyi and Lin Xi began to prepare the medicine carefully at the same time.

Because he has great trust in Lin Xi, and his sense of time is not as accurate as Lin Xi's, he must always pay attention to the large and small hourglasses around him to calculate time, so An Keyi's energy is all concentrated on the medicine he prepared.

, did not notice at all that in the first two minutes, when the three medicinal liquids were mixed and the fourth medicinal liquid, Seven Star Herbal Liquid, was added, Lin Xi did not follow her previous instructions, but added a full nine drops of Seven Star Herbal Liquid.

inside.

The two of them finished the medicine at the same time with a tacit understanding, and handed it all to Lin Xi. It was still a bottle of dark red medicine and dark cyan medicine mixed together. Under Lin Xi's constant shaking, two minutes later, this

The two medicinal liquids reacted completely, merged completely, and turned into a transparent, molten blue gel-like substance. From the appearance, there was no abnormality at all compared to the last time.

Because she 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 blood and soul pills of the strong men in Purgatory Mountain, and dropped three drops.

Drop the blue liquid you prepared this time into it.

"laugh!"

An unexpected puff of green smoke rushed out from the mouth of the glass medicine bottle.

However, what made Lin Xi's eyes widen instantly and her breathing stopped for a moment was that this time the black blood in the glass medicine bottle was almost completely boiling, and the moment the three drops of medicine spread, the black blood in the entire medicine bottle

Everything turned bright red!

An Keyi fell silent instantly.

It's just that this time her lips trembled slightly, but there was an uncontrollable bright red on her face.

Lin Xi got the answer from An Keyi's expression. Looking at the thick smoke dissipating from the mouth of the bottle, and looking at the bright red color completely transformed in the glass medicine bottle, Lin Xi was excited and couldn't help but sigh sincerely: "The pharmacology in this world is...

It is indeed very profound..."

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

This immediately made Lin Xi feel at a loss. In the past few years, the tutor in Lulin Town immediately asked him to return the favor immediately.

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

Obviously, An Keyi is not the only one who has devoted a lot to this topic.

Fortunately, this project was successful after all.

"Although Vice President Xia said that this bottle of medicinal solution is for you as a reward, and he may not have his own reasons, this bottle of medicinal solution is very precious. Don't waste it when you use it in the future." After another few minutes of silence.

, An Keyi looked at Lin Xi and said: "Based on the potency of the medicine just now, you should only need to apply a thin layer on the weapon. If some of the potion can penetrate into the opponent's skin, it should be effective."

"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 masters like Purgatory Mountain and used for magic transformation." After Lin Xi nodded and put away the crystal drop bottle, An Keyi added.

Explained: "After all, Purgatory Mountain is like other places of cultivation. There are some secrets that we cannot understand, so it is best to use this after the monks of Purgatory Mountain who have truly transformed the enemy monsters. And it is best not to leave any survivors alive once used..."

This is the secret of our Qingluan Academy."

"Student understands." Lin Xi thought that she might not be able to explain the seven-star herbal liquid that she had poured in too much. After thinking about it, she looked at An Keyi and said: "Teacher, although this prescription has been researched, the materials are rare...

I’m afraid it will take several more years to get the materials together?”

At this moment, it was completely successful. After An Keyi was excited, he returned to his usual temperament and said calmly: "Yes, it should take three or four years at the earliest. During these three or four years, the main tasks of some lecturers in our Imperial Medicine Department should be

We just have to try to find and cultivate a few of the main medicinal herbs...but it should take a few years. After a few years, we may be able to refine a lot of this medicinal liquid."

Thinking that since it was determined to be a few years later, she didn't need to be too impatient. After Lin Xi smiled slightly in her heart, she looked at An Keyi extremely seriously and said, "The student has a request. I don't know if the teacher can agree to it."

An Keyi frowned slightly, thinking don't take the opportunity to make some greedy demands, otherwise my opinion of you will be greatly changed. But what made her slightly stunned was that Lin Xi said: "This is very important to me.

It is very meaningful, and I also have experience, so next time I want to refine this liquid, I still want to ask the teacher to refine it with me."

"That's fine." An Keyi pondered for a moment and said, "Even if the medicinal materials can be successfully cultivated in the future and more of this medicinal liquid can be refined, the prescription will always be a secret of the academy. It is naturally best for you and me to refine it.

I have the right to promise you this."

Seeing An Keyi's current appearance, and then thinking of An Keyi's sad look just now, Lin Xi felt bright in her heart and smiled slightly: "Then student, please thank the teacher in advance. Since I have the final say on this medicine, do you want me to do it?"

Give some to the teacher first?"

An Keyi thought about it seriously and shook his head: "I don't have many opportunities to leave Qingluan Academy... This liquid is originally intended for students who go out to practice and perform tasks, and it is to be used in times of danger... But

After all, it is still in the confidentiality stage, so even if you go out in the future and encounter danger, if your companions want to use it, they should still hide it."

Lin Xi thought for a while and nodded.

An Keyi also nodded and said in a reading-like tone:

"You need a lot of time to practice... My classes here have ended, so starting from tomorrow, you don't have to come here."

"I will report the success news later. You can get the reward of two credits as soon as you go out. This time I suggest you redeem the Soul Gathering Pill, which should be able to help you improve your cultivation a lot."

"In the future, if you don't understand anything about bonus credit redemption, pharmacology, etc., you can come over and ask me directly...Also, if I am assigned a new research subject and need your help, are you interested in helping me again?

?”

After hearing the first sentence, Lin Xi felt a little disappointed, but after hearing the next two sentences, Lin Xi was immediately filled with joy, with a bright smile on her face: "Of course I'm interested."

***

(Last night, Blue Sea was still asking me how much I would like to add to the bachelor's degree, because Dahai's support is not far away from the bachelor's degree. I gave "Da Dahai" some mercy, because I did write this book slowly and relatively slowly.

Fine, and now that I am a father and over 30 years old, I have to take on a lot of responsibilities. Playing with my daughter in the sand on Children’s Day has to consume some manuscripts. In order to maintain stable updates, I have devoted myself to books and book friends.

Too much, and too little for my family and friends around me. Many times when I sleep, I think about what I can do to compensate for it in the future... In order to write a book, my classmate could only spare one day when he came to Wuxi.

I even missed ten years of college class reunions to entertain and write a book. When my college classmates and buddies in our dormitory took turns calling me, I really wanted to cry. But right now

Because I have paid a lot, I have to write better, so I would rather make less money, write what I want to write, and strive to make great progress with each book. In this life

, there are many regrets, but what I pursue is nothing more than a clear conscience and inner peace. I have always loved fantasy, and I have always imagined that if I were a knight in ancient times, walking among the bamboo forests in the night rain, I would be happy and happy.

..Having one or two close friends in life is enough, and now there are so many book friends who can understand and support me, so I feel at ease and work very hard to tell the story calmly and strive to be the best. I originally agreed with Dahai,

Slowly reward me to be a bachelor, and let me accumulate more and revise more manuscripts. When I woke up in the morning, I saw that Fang Lianhai suddenly joined the bachelor. I thought that I had to work hard at the same time, but I was still very touched. So I am destined to add more than one update today.

.For Fang Lianhai, for the sea, for the sun, for cheap guests, wood, bullshit, Hongyue, etc., Kewen, Jazz, Miaomiao, etc... I have always wanted to make a list of all the people I want to thank, and

Send a leaflet to every book friend who supports me, because even 100 Zongheng coins is recognition and encouragement for me. I love you book fans who are worthy of love, and I like to communicate with you, but this also requires

Time, and what I am lacking now is time... I think there will be a sunny afternoon in the future, where everyone will gather together and chat happily and quietly. Finally, thank you again for your support... I can't repay it

, I continued to meditate and code as hard as I could)
Chapter completed!
