"Are you an alchemist?" Lu Qinghan's tone was surprised, and his eyes were a little suspicious.

It's not that she doesn't believe it, refiners are a very respected profession in the Lingyin Realm, and they are all valuable talents who eat in the major sects.

And their preferential treatment is naturally not for nothing, refining is a university question, involving talisman making, alchemy, casting, alchemy, and even organ formations, a monk walking in the rivers and lakes, naturally needs to take advantage of the weapons and unique magic weapons, a sect stands in the spiritual hidden realm, and naturally needs big guys such as mountain protection arrays.

"Me." Zhao Ziyu didn't expect Mu Lan to push herself out directly, and she didn't know what her intentions were, so she scratched her hair embarrassedly.

"I'm just a half-ass."

He said that Lu Qinghan finally breathed a sigh of relief, if she was an apprentice, it would be normal, she belonged to this level.

"But this sigil of yours is really good." Lu Qinghan carefully looked at the wind control formula, she couldn't understand the rune circuit on it, but the overall appearance was extremely concise, and she immediately tested it according to the formula given to her by Zhao Ziyu, and the figure disappeared in an instant, leaving an afterimage.

"Fu Seal?" Zhao Ziyu asked a question, and then understood that she was talking about rune paper, and it turned out that the Spirit Hidden Realm was called this.

Qinghui Mune's eyes flickered, and someone slapped him on the head just now.

"Senior sister?"

Lu Qinghan suddenly laughed, and used his speed advantage to secretly take off his senior brother's jade pendant.

"Qinghan?"

The two brothers were teased, and Lu Qinghan returned to the place with a lot of fun.

"The effect is very good, and the materials and circuits of the rune seal are very simple, it is simply ingenious!" Lu Qinghan gently stroked the rune paper, and asked Zhao Ziyu with a curious expression: "I don't know which sect your master is a great cultivator?" ”

Zhao Ziyu thought to himself that he had no master, he was all self-taught, and if he wanted to talk about the master, it could only be the main god system with vast supernatural powers, after all, the system could be directly exchanged for the top refining knowledge.

Silently looking at Mu Lan, her blueprint also has a lot of credit, in order to help herself refine weapons, Mu Lan also redeemed the "Runes and Treasures Refining", and has become a refining consultant who has not cultivated.

Zhao Ziyu and Lu Qinghan began to exchange experiences in refining weapons, and he found that these runes produced by Qiyunguan were very interesting, with unique rune circuits and effects, and they were not even included in the main god system, but the structure was too complicated and cumbersome, and it was obviously not as concise as the method provided by the main god system.

"For example, this Cloud Burst Talisman is similar to Yiyi's explosive arrow ability, but there are too many effects, and the circuit is too complicated, so it is not easy to achieve mass production." Zhao Ziyu took this Cloud Burst Talisman, and its whole body was a spar piece, with a dodecahedron structure, which was produced from a precious spiritual vein.

The refining device is to put the rune circuit into a carrier, making it portable and miniaturized, and the rune circuit is similar to the energy conversion line of scientific and technological civilization, just like the mobile phone that Zhao Ziyu usually uses, and a small square can complete many functions.

And Lu Qinghan's talisman seal is a little complicated, Zhao Ziyu carefully analyzed, and found that it contains at least four magic arrays, the spirit sealing array can avoid the dispersion of spiritual energy, and the core cloud explosion array makes it explode, as for the hidden spirit array, is it to make the circuit hidden and more beautiful? The final Spirit Gathering Array is even more strange, this kind of thing is a one-time product, is it possible to gather spiritual energy and reuse it?

"You know a lot......" Lu Qinghan was shocked, she just constructed according to the secret book passed down by her master, and didn't think about so many things at all, and Zhao Ziyu talked about the internal structure very well, you must know that even she didn't understand the many circuit structures inside.

"It's just copying, it's not creative." Mu Lan commented in the Mind Link.

Zhao Ziyu agreed, while Lu Qinghan continued to ask: "Also, what do you mean by mass production?" ”

"It's mass production." Zhao Ziyu is playing around, he comes from an era of great industrialization with the explosion of science and technology, and his thinking is naturally much more modern, after making the first talisman, he and Mu Lan pondered how to produce more things with the same structure with less effort.

"It's an analogy." Mu Lan explained to Lu Qinghan: "Your Cloud Burst Talisman can discard the useless circuit structure, and only keep the Spirit Sealing Array and Cloud Burst Array, so that the materials can also be saved a lot, and it can be used to make more identical talismans." ”

She looked at Lu Qinghan, who was lost in thought, and chuckled: "We can even introduce an assembly line." ”

"Assemblies?"

"That's right." Looking at the three senior brothers who were surrounded as if listening to the teacher's lecture, Mu Lan didn't have the intention of showing off, but continued: "Use the most economical materials, the most concise structure, and then a special person is responsible for one direction, for example, the junior brother will get the materials refined, the senior brother will be responsible for condensing the formation, and you ......"

Mu Lan looked at Lu Qinghan, who was listening carefully and seemed a little well-behaved, "You with the most experience will finally engrave the inscription and instill your strength." ”

Mu Lan pondered, and even the process can be subdivided a little more, from the process of material refining, there are purification, forging and additional auxiliary materials, but there are only a few people in Qiyunguan, and Uncle Sun in the back kitchen doesn't look like he has cultivation......

"It's not that easy."

Everyone looked back one after another, and at some point, the Cloud Sky Daoist in a sloppy robe stood behind him.

He shook his head and said, "Even if the circuit is streamlined, what are you talking about...... assembly line, then our materials are not enough. ”

Daoist Yunxiao looked at those incomprehensible amber eyes, and said regretfully, "Do you know why natural spirit stones are so precious, and even most of the cast spirit stones are mixed with impurities?" ”

"I don't know ......"

"There may be no shortage of spiritual energy in the place where you are, but the spiritual hidden realm ......"

Yunxiao Daoist looked over the courtyard and looked at Sanqing Mountain in the distance, he sighed: "The aura is getting thinner and thinner, it is no longer the same as the ten thousand immortals who flew up tens of thousands of years ago, and even finding a rich spiritual vein is the big news that shocks the East Pole Prefecture, and the big and small sects will definitely compete for it." ”

"So, is this also the reason why the cultivation of the Spirit Hidden Realm cultivators has stagnated?" Mu Lan asked.

Daoist Yunxiao nodded, took out his wine gourd, and slowly left.

"I think I know what you're thinking." Zhao Ziyu said in the Mind Link: "Do you want to open my rune laboratory in the Spirit Hidden Realm? ”

"But they don't have enough materials, but I remember you ......"

Mu Lan didn't answer, she did have several boxes of materials, and when combined with Qiyunguan's refining system, she could achieve the idea in her heart.

However, the words of the Cloud Daoist made her think in another direction, and she had doubts, and she began to feel that this spirit hidden realm was a little strange.
