"Then may I ask Hall Master Chen, this Yan Dan is here..."Xiao Tian listened to the other party say what he was looking for, and hurriedly wanted to continue asking, but was interrupted.

"Senior nephew, as the name suggests, this Yan Dan can keep people's faces unchanged, although it can only last for fifty or sixty years, it is enough for mortals. Without waiting for Xiao Tian to finish asking, Hall Master Chen said the effect of the Zhuyan Dan, as if he had something else to say.

"That's great, Hall Master Chen, I..." Xiao Tian was interrupted by the other party before he could finish asking this question, which made him a little strange.

"The nephew must want to ask about the refining method of this pill, but unfortunately, this Zhuyan Pill is basically impossible to get, so the nephew should give up. Hall Master Chen stroked his chin and said to Xiao Tianzheng.

"Ahh

The other party interrupted his question just to say this? I don't even want to waste time to say a reason? But looking at the other party's appearance, it seems that he is waiting for himself to ask, what kind of trap can't be achieved?

No matter what, you still have to ask clearly before speaking, Xiao Tian doesn't care if there is a trap or not, he salutes Hall Master Chen and asks: "Please explain to the disciple Hall Master Chen, the disciple will not give up easily if he does not understand the reason." ”

"It's very simple, the medicinal materials needed for this Yan Dan are really precious and difficult to find, and even some hundreds of thousands of years of elixirs are used as raw materials, and where can the master and nephew of these precious medicinal materials go to find them? There is no hope for Hua Lingshi to buy the Zhuyan Pill, which immortal cultivator has a spirit grass of more than a thousand years, and the one who is not precious is regarded as a heart, how can it be wasted on this pair of Zhuyan Dan that is useless for cultivation?"

As Hall Master Chen said, it is impossible to refine this Zhuyan Dan, the most precious medicinal materials he has come into contact with are two or three hundred years of medicinal properties, and the price has already made Xiao Tian embarrassed, how can he get medicinal materials that are more than a thousand years old. Unless he can be like the male protagonist in the novel he read in his previous life, he can promote the growth of medicinal herbs by himself, but compared to having such an unrealistic dream, Xiaotian still wants to find some reliable way.

Isn't there any way to make the raw materials of Zhuyan Dan easier to use, or can you use some easy ingredients to refine it?

That's right, as long as the formula can be improved, can't it be refined with some easy-to-get medicinal materials? Thinking of the formula that I got on the hill in Zhangzhou before, as long as I can improve it with reference to that method, it is also possible to refine this Zhuyan Dan.

"Hall Master Chen, I still want to ask about the formula of the Zhuyan Pill, maybe I can improve the formula and refine it with some easy-to-find medicinal materials. Xiao Tian said what he thought.

"Hahahaha," Hall Master Chen laughed when he heard this, "Senior Nephew is really a malleable talent, and he thought of the direction of improving the formula so quickly, which is exactly what I want to say." "It turns out that this Hall Master Chen has always wanted to guide Xiao Tian to ask about improving the formula.

"So, this recipe can really be improved?" Xiao Tian was overjoyed when he heard this, and felt that he had finally grasped a glimmer of hope.

"Yes, but it's a pity, let me tell my nephew about this matter slowly. Hall Master Chen was ready to make a long speech and motioned to Xiao Tian not to interject.

"I have a recipe for the Zhuyan Pill in my hand right now, and the raw material it requires is what I said requires a medicinal herb that has medicinal properties for more than a thousand years. And this recipe has actually been improved and handed down over thousands of years. This Zhuyan Dan has been around since ancient times, and it is impossible to find the corresponding raw materials for the original formula. And there have been so many monks throughout the ages, and there are still many people who want to maintain their appearance, so they have slowly improved the current formula. Master Chen first introduced the origin of the formula of Zhuyan Dan.

"Now that the aura between heaven and earth is becoming more and more scarce, the growth of heaven and earth elixir has also become difficult, and it is not easy to refine some pills that are useful for cultivation. If you want to maintain a youthful appearance, it is easier to practice some secret techniques, and gradually no one pursues this Zhuyan Pill anymore. After the demand for Zhuyan Dan decreased, naturally no one improved it, and my formula has not changed for thousands of years. "This recipe hasn't changed for thousands of years?

"When it comes to improving formulations, it's not that easy. Everything is gradual, and this is especially true for formulation improvements. To improve the formula of the elixir, we can only use different medicinal materials, try to replace one of the raw materials little by little, and finally develop a new formula. To improve the original recipe, you have to try countless times, and countless raw materials are wasted. And those precious pills, almost all of the medicinal materials they need are particularly precious, and they themselves are difficult to refine, and if you want to improve their formulas, it is difficult to succeed in spending sky-high spirit stones. The same is true for the recipe of this Zhuyan Dan, if you want to improve its ingredients a little, it will take countless materials and time. Hall Master Chen said something that disappointed Xiao Tian again.

"To improve the formula, you must first be very good at refining pills, otherwise you can't be sure whether the reason for the refining failure is the raw materials used. Although the master and nephew can refine a lot of ordinary pills now, the way of alchemy is far from being proficient, and it is even far from being an alchemy master. "Hall Master Chen finally said what he wanted to say the most, as long as Xiao Tian still wanted to try to improve the formula of the Zhuyan Pill, he would definitely have to come to the Dan Heart Hall to hone his alchemy skills.

"In addition, to improve the formula of an elixir, it is best to collect all the formulas of this elixir, and the more original the formula, the better. After comparing several formulas with each other, it is possible to deduce the active ingredients required for this elixir, and try to replace them with some raw materials with similar medicinal effects. Hall Master Chen added.

"Then where can I find the other formulas of this Zhuyan Pill?" Xiao Tian has already decided that he must come to Danxin Hall to continue learning alchemy in the future, and it is more important to collect the formula in advance.

"The formula for this Zhu Yan Dan is really hard to find, as far as I know, there is no other formula in the entire Qi country that is different from mine. However, if it is an ancient formula, there is really a place where you can get it easily, and there may be a recipe for this Zhuyan Dan. Hall Master Chen explained to Xiao Tian with a smile.

Where is the place that Hall Master Chen is referring to? Looking at what he means, how does it seem to be related to himself?
