Tang Yun didn't respond to Qin Zha's refusal.

She is a relatively rational woman.

It's true that I want to be a teacher.

But in essence, she paid homage to her teacher to let Qin Zha point out her alchemy, not to make some kind of connection.

Qin zhe says that he needs Longhan's prescription to refine and verify his pharmacology. At that time, he is allowed to watch, and Tang Yun's eyes brighten.

Tang Yun didn't expect to learn the alchemy of Qin Zha.

Too much to chew.

Long Han's Alchemy she did not study thoroughly, turned his head and focused on another alchemy, she was not so stupid.

What's more, Qin Zha may not teach her?

But watching the refining process, she may have a lot of benefits.

It is true that the two different systems of alchemy will not communicate with each other, but the value of observation and reference is very high.

Without any hesitation, Tang Yunsu turned his hand and found a manuscript bound with thread paper.

"Qin Zhenxian, the master of dragon and Han Dan, is very precious. Even the disciples who close the door can hardly get his true biography. Tang Yun's alchemy was taught by his father in his early years, and he had never learned from his teacher. Therefore, most of the prescriptions he knew were widely spread in Longhan, but I spent a lot of money to collect some. It took me six years to record this handwritten copy, which records my personal views and experience on Longhan Danshu and all the danfang I know. If Qin Zhenxian doesn't dislike it, he'll take it to review. "

Seeing that Tang Yun didn't say a word, Qin Zha took out a copy and handed it over. He couldn't help looking at her strangely.

It has to be said that Tang Yun is to his taste in some way.

Maybe it's because of being an official in the court. Tang Yunsheng doesn't have too much cowardice in his nature. He has his own unique views on people and things.

Besides, Tang Yun is a real person.

He saw that Tang Yunfei wanted to get on the line with him, just to learn Dan Shu.

At the moment, he clearly only wanted danfang, and he didn't say how many.

Tang Yunsi is unambiguous and directly copies out the records he has spent for many years.

It not only contains all the danfang she knows, but also her personal experience and insights from studying Longhan Danshu.

Facing Tang Yun's real action, Qin zhe hesitated.

Tang Yun's desire for refined alchemy lies there.

In essence, he just wanted to cheat a few Dan Fang to practice.

Guidance?

What can he tell Tang Yun?

What he can do, at most, is to let the latter watch the alchemy.

Qin Zha has always been a man of principle.

If Tang Yun plays tricks on him, he will fool others.

People are so sincere that it is necessary for him to show some practical ideas.

Looking down at the jade hand handed out by Tang Yun, Qin Zha takes over the manuscript for a moment in silence, and gives her a point in the middle of her eyebrows, instilling the star spirit Jue Lian into her mind.

Although I don't know how Longhan's alchemy is, it can't compare with Xingshen Jue Lian.

Teach people, he won't.

It's more practical than anything to teach her star God Jue Lian directly.

He didn't say that he would not be allowed to pass it on when he was taught star God juejian by horizontal and vertical shallow ring tone, which was also very casual at that time.

And in fact, Professor Qian Lingyin only gave the formula of Xingshen juejian.

In light tones.

Dan Dao theory is indispensable, but the theory is not said by others, we need to explore.

Tang Yun is totally unprepared for Qin Zha. Leng buting is pointed in the middle of his eyebrow and can't help shivering.

Then, the star God Jue Lian formula in her mind made her face change again and again.

Longhan's alchemy is not bad.

But just as Qin Zha thought, the dragon and Han Dan technique could not be compared with the star God Jue Lian.

No matter how hard it is, the star God Jueling also belongs to the ancient and powerful star clan.

Tang Yun is the master of goods.

When she first saw the formula in her mind, she was immediately attracted, but did not indulge in it.

Because at a glance, she could see that this was not the top-level Dan Shu that she could start immediately. It was not advisable to immerse rashly.

Tang Yun's mind is restrained by force.

At this time, Qin Zha was already sitting on one side, holding her manual and looking at it.

Seeing Qin Zha sitting there with a flat face, Tang Yun stepped forward two steps and bent his knees without saying a word.

However, Qin Zha seemed to have foreseen that before her knee touched the bottom, he waved a chaotic force and looked up at her. Without making any words, he continued to read the manuscripts.

Seeing this, Tang Yun stands up straight, then hesitates to come over.

"Teacher..."

"Don't make any noise."

Qin Zha made a "tut" sound.

A "master" to the mouth failed to shout out, Tang Yun reluctantly bite red lips.

Qin Zha suddenly spread her star God Jue Lian, that she did not expect.

It's not so easy to start with the top Dan Dao.Call Qin zhe a "master", she is willing, but someone is not willing to bear.

Qin Zha, a well-dressed and grateful beauty, doesn't even take a look at her. Tang Yun has no choice but to turn around and walk outside the hall to bring in the clothes sent by the servants before, and then sit quietly to one side.

……

With Tang Yun's handwriting in hand, Qin Zha checked the Danshu of fan Longhan, but soon lost interest.

It's not that he can't understand how rough longhandan is.

He set foot in Dan Dao by logging in star God Jue Lian on the status bar. He didn't understand it at all.

Tang Yun's handwriting records the theory and opinions of alchemy, which is just like the obscure book of heaven in his eyes.

People don't have to be against themselves.

So Qin Zha chose to give up.

Turning to the record of Dan Fang, Qin Zha frowned slightly.

There are a lot of Dan prescriptions recorded in the manuscripts, which are closely related to practice.

Only on the first page, he saw more than ten Dan prescriptions that played different roles in practice.

It is not difficult to see that there is a great demand for elixir in the practice system of the Longhan people, and it is impossible without elixir.

But that's not the point.

The point is that every Dan prescription Qin Zha saw had the same material, xianlingyin.

Xianlingyin is a tribute from the marginal city to Longhan.

Qin Zha has learned this through Yunxi and Yunque's mother and daughter.

But he didn't expect that this kind of thing that he thought was weeds would be widely used in Longhan danfang.

In the final analysis, xianlingyin is not a spiritual thing at all. Why is it used for alchemy?

Looking up at Tang Yun, Qin zhe inquires.

"What's the point of xianlingyin?"

In response to Qin Zha's question, Tang Yun obviously had foreknowledge and answered it in a soft voice.

"Since the founding of the people's Republic of China, Xianling Yin has been a necessary medicine in Longhan Danshu. This kind of Xianzhi has a unique effect, which can effectively purify the impurities and toxicity in pills, and will not affect the efficacy of other drugs. "

While speaking, she looked at Qin Zha's expression and continued.

"Master, it's not very precious to Longhan, but it's very difficult to get it. Its source is the tribute once every three years from the absolute edge city, which is very far away from Longhan. Every time they pay tribute to the Imperial Palace, they will reserve a part of it. When they stay in the upper boundary of sacrifice, they will be sent to the national master to go outside the territory, and the rest will be distributed to the Dan master according to the number of people. "

"Is there a demand for immortals outside China?"

Qin zhe frowned and ignored the "master" in Tang Yun's mouth.

Tang Yun shouts and is ignored. He doesn't get discouraged and goes on.

"There are not many requirements outside the territory. I'm afraid I can only ask the national teacher what to do. As far as this fairy tale is concerned, I know a little-known legend. It's said that xianlingyin is a useless herb, but its essence has changed after bathing in the blood of gods. Taking xianlingyin can make mortals have the blood of gods. "
