A few people ran around all afternoon, and there was no useful information at all.

Tang Nanzhi said: "I asked a few shops that have a long-term cooperative relationship with Suding Palace, and they all said that the aura in the pill was suddenly gone. ”

The word "suddenly?" encompasses a lot of questions. Zi Sang Muxi said, "No one knows why?"

Tang Nanzhi shook his head and answered: "The disappearance of the aura is not a trivial matter, and in the process of alchemy and medicine, there is only a group of mortals around. Even if the problem is in front of them, they can't see it......"

Also......

"When did the aura disappear? During the alchemy process, or did it slowly disappear after the pill was refined?"

"After the pill here is made, it will use rune paper to verify the amount of aura it contains. Tang Nanzhi said, "The recently released elixir, when it was verified, was already completely devoid of aura. ”

Lu Li asked, "In this case, could it be that there is something wrong with the process of alchemy?"

"It shouldn't be likely...... The alchemy process here is more than 100 years old. There is no sudden innovation, or a change of tools or anything, and there is no possibility that the process will go wrong and make the aura disappear......"

That's not right, that's not possible.

After discussing it for a long time, I didn't have a clue at all.

Mu Ranran said: "Now that I think about it, it's not very difficult to find the reason when I am in Taohe Town...... Why can't you find fault here?"

Is that......

It is indeed not difficult to find the reason for those people who suddenly fainted. The branch line and the main line are hooked, and after brushing the branch line, the main line will continue normally.

This way......

Zisang Muxi said: "The spiritual veins of heaven and earth are normal, and everything is no different from usual. It's just that the key thing like aura is gone...... It's a lot more serious than it was in Peachkawa. If it is man-made, it must be more careful, and it is not easy to find clues. ”

"So what now?" Cheng Yan asked, "and then brush the branch?"

Zisang Muxi shook his head - most of the people here are from alchemy and medicine, and even they don't know where the reason is, so what's the use of continuing to ask them?

"Use the elimination method first, find the problem one by one, if it's all right, then it can only be artificial. ”

"Raise your hand and ask! How should this elimination method be operated?"

Zi Sang Muxi looked at the Cheng Yan who asked the question and said, "You know this better than me...... First list the process of alchemy carefully, and then find the problems one by one. In the beginning, it must have been raw materials, right?"

Tang Nanzhi nodded: "I understand, I'll write out the list later......"

"Why do you use the ......book of heaven to write?" Zi Sang Muxi snapped his fingers and let the book of heaven come out, "Open a document for Zhizhi, and send it to the fellow villagers after it is written, and let the old Fu and Lao Zhang, who are far away in the Broken Cloud Sect, help find some way." ”

Cheng Yan didn't understand: "Okay, why do you suddenly q the two of them?"

Zi Sang Muxi tilted his head and said strangely: "Isn't it right? Maintaining the relationship between friends, isn't it just to talk about everything and everything?"

The others didn't think there was anything wrong with this, and thought that Zi Sang Muxi was joking.

Only Lu Li, when he was unprepared, frowned.

......

......

Return to the hotel.

Zisang Muxi helped Tang Nanzhi get a document out, and used the book of heaven to pass it to the chat group of Qianli Chuanyin.

[Xuanmen Second Goods]: Can you really share files?

[Tang Nanzhi]: By the way, Mu Xi, didn't you upgrade the Book of Heaven last time? What new features have been added?

Upgrade the Book of Heaven?

Oh......

That's just an excuse......

But you can't say it explicitly......

[Zi Sang Muxi]: Forehead...... Upgrade failed...... I'd better go back and ask the second senior brother to get it again......

[Xuanmen Second Goods]: Yes, don't toss around by yourself and break it again. There is no place for repairs here......

[Lu Li]: Shall we follow the steps on this table and investigate them one by one?

[Zi Sang Muxi]: Well, let's start with the raw materials!

In Yantai Mansion, everyone is alchemy.

It's just that the origin of the raw materials is very complicated......

Those who come from the south to the north, as long as they pass by this Yantai Mansion, will bring some raw materials with them.

From all kinds of flowers and plants to rare treasures that are difficult to distinguish between true and false.

Money, not a problem for people here.

Especially for those who like to engage in innovative pills, it is also common for a daughter to buy a raw material that they need.

In this way, it is difficult to find problems......

A few people first shopped the raw materials in the city, and these were no problem. But what about those who flow?

Zisang Muxi thought for a while and said, "I remember that someone registered at the city gate when I came in. Know, can you get the registration form?"

"This one does. "The name of Suding Palace is rarely not easy to use.

Zi Sang Muxi wanted to find out from the registration form to see if there was anyone who had come here to sell raw materials for a long time. After all, there are not one or two problematic situations, and the pills from Yantai Mansion have all been devoid of aura recently.

If it's a matter of raw materials, then the quantity is large.

The purpose of the visit is indicated on the registration form, and the focus is on those who come here specifically to sell raw materials, and who have registered a large number of raw materials.

After finding a few, Zisang Muxi was not in a hurry to check people directly. Instead, I asked Tang Nanzhi first-

"Zhizhi, if you look at these raw materials, are there any alchemy pills that must be put in them......? No matter what kind of medicine, you need to put a taste of raw materials?"

Tang Nanzhi looked at it carefully, and then shook his head: "There are no medicinal materials that all pills need, but this Zheng Kun, the raw materials he brought are all basic medicinal materials, although not all pills need to be used, but from the overall situation, these are all basic raw materials, one can't be used, and the other will be used." ”

"In other words, on the whole, this Zheng Kun's raw materials are the most commonly used and the most abundant?"

"If you just look at the ingredients, yes. ”

Zi Sang Muxi looked at the information on the registration form, Zheng Kun's identity is a businessman, and unlike those who are businessmen and passers-by and see doctors, he is just a businessman.

It seems that it is a businessman who specializes in providing raw materials for the major alchemy factories in Yantai Prefecture.

Cheng Yan believes: "That person doesn't necessarily buy his things, the same raw materials, not only he is selling." ”

Zisang Muxi nodded: "You're right. But the problem of raw materials, it seems that only Zheng Kun is not sure here. The number of him is large enough, and the more aspects involved in the various alchemy factories will be. If he can be sure that there is no problem with his raw materials, then the problem will not be with the raw materials. ”

Tang Nanzhi agreed: "Zheng Kun has been in Yantai Mansion recently, shall we go directly?"

Zi Sang Muxi thought about it, and finally decided to go directly to Zheng Kun.

Those who dare to stay under the noses of a group of monks are either really okay or 100% sure that they will not be discovered.

If it is the latter, the cliché of beating around the bush will definitely not have an effect.

Crisply, to the point.
