Using the true yuan to carve traces in some jade, in order to convey some information that is inconvenient to express in words, this is not a very powerful means, and it only requires strict control of the true yuan.

Therefore, when Yang Zhen saw Yang Kai take out two pieces of jade, he knew that there must be some famous halls in the Dao.

The Divine Sense reached into it, scrutinizing it.

Suddenly, Yang Zhen's brows furrowed, his eyes became solemn, and after a while, his eyes were full of doubts, and then turned into surprise and consternation.

With the change of his eyes, the expression on Yang Zhen's face was also extremely exciting.

The old men who were going to watch the show couldn't help but be stunned for a moment when they saw Yang Zhen's expression, wondering if he had found something amazing.

After a long moment, Yang Zhen took a deep breath, slowly withdrew his divine sense that had penetrated into the jade, glanced at Yang Kai with an extremely strange look, and pinched another piece of jade with a solemn expression.

Continuing to investigate as he did just now, as if the incident was being replayed, the various changes in expression on Yang Zhen's face were interpreted again.

Several white-haired elders in the hall couldn't sit still, and they all stood up one by one without knowing when, and quietly gathered over to this side.

In a moment, Yang Kai was squeezed out of the outermost area, and the old guys gathered together, all waiting for Yang Zhen to retract his divine sense.

"What's in there?" An honest man couldn't hold back his doubts, wondering what Yang Kai had brought to attract Yang Zhen's attention, and as he spoke, he reached out to take the piece of jade that was placed on the table.

Before he could get his hands on it, he was grabbed back by Yang Zhen, and the other party glared at him.

"That kid come over to me!" Yang Zhen waved his hand, unceremoniously pushing the probe elders aside.

"The disciple is here. Yang Kai stepped forward, if you really want to count it, Yang Zhen should be a figure of his grandfather's generation, but in the Yang family. Generally, they are not referred to as relatives, unless they have a good relationship.

Holding the two pieces of jade, Yang Zhen frowned, his old face couldn't help but blush, and he asked in a muffled voice, "What is this?"

"I don't know what it is that you are doing so wonderfully?" a white-haired elder was stunned, and the others also shook their heads slowly, and the expectations in their hearts suddenly decreased a lot.

"Two sets of spirit arrays. ”

"Nonsense. Yang Zhen snorted lightly, "The old man is not a fool. Of course, the Zhilu Dao is two sets of spirit arrays. What I asked was what it was for. ”

As he spoke, the old face turned even redder.

He is a lot old and has a lot of experience, and at this moment, he can't even identify what a young man with a grandchild has brought back, so he naturally feels a little embarrassed.

Yang Kai pinched his nose: "Alchemy's Spirit Array!"

Yang Zhen was stunned: "For alchemy?"

As he spoke, he kept shaking his head and said, "The old man of the spirit array used in alchemy has seen a lot. But there has never been a spirit array as complicated and complicated as you brought, and it is quite a troublesome thing for such a spirit array to be carved on the Dan furnace, if it is used for alchemy. It will inevitably consume more energy and true yuan from the alchemist, are you sure that these two sets of spirit arrays are effective?"

"Sure!"

"Tell me, what are they all for?" Yang Zhen asked with a frown. He didn't know much about alchemy, so naturally he couldn't see the magic and mystery contained in the spirit array, but he subconsciously felt that these two sets of spirit arrays were a little too complicated and mysterious, although they were definitely good things, but there were definitely drawbacks.

"One of them. It can increase the success rate of alchemy. Yang Kai introduced with a flat expression, "In other words, if an alchemist's usual chance of becoming an alchemist is only sixty percent, then with this set of spirit arrays, it can reach ninety percent!"

Yang Zhen couldn't help but be moved.

Even if he no longer understands alchemy, he also knows how good an alchemist is who can guarantee a ninety percent success rate. Ordinary alchemists can only guarantee a rate of six or seven percent of the pills, and ten alchemy materials can almost only refine six or seven pills.

The better alchemists are about eighty percent, and most of the disciples from the Medicine King Valley are at this level. And now, a spirit array can increase the success rate by 30%, doesn't this mean that as long as a slightly better alchemist uses this spirit array, he can 100% ensure that the pill is completed?

Over the years, how much material does this have to save, and how much time and energy can it save?

In an instant, Yang Zhen realized the preciousness of this set of spirit arrays.

Of course, the premise is that what Yang Kai said is true.

"What about the other set?" Yang Zhen asked in a calm tone, holding back the shock in his heart.

"There is a chance to improve the quality of the elixir!" Yang Kai said lightly.

"What do you mean?" Yang Zhen subconsciously frowned, and hurriedly asked, his breath was held, if his understanding was correct, then the value of this set of spirit arrays was even greater than the one just now!

"Originally, refining a furnace of heaven-level mid-grade pills, using this spirit array, there was a chance that a heaven-level high-grade pill would appear. Yang Kai patiently explained, and added, "This probability is not very large, but it will always appear!"

The elders' breathing suddenly became short, and they could also see the value of this set of spirit arrays.

One of them asked a little nervously, "What if it's refining a furnace of Xuan-level Upper Grade Pill?"

Yang Kai shrugged his shoulders and smiled, "I wonder if there will be a spirit-level elixir." ”

These two words were like war drums beating in their ears, shaking the eardrums of several elders, and they all looked at Yang Kai incredulously, trying to see if there was any trace of joking on his face.

Yang Kai was calm!

These two sets of spirit arrays were all comprehended by him from the alchemy true formula, and it was obviously impossible for them to be useless.

The entire Hall of Elders was silent in an instant, and a group of old guys were stunned in place, not knowing what to do, all of them were thinking about the value of the Spirit Array, and the truth of Yang Kai's words.

After a long moment, Yang Zhen suddenly came back to his senses, looked at Yang Kai with an extremely stern gaze, and said coldly: "Do you know what kind of crime it is to fool the Hall of Elders? Even if you are a descendant of the Yang family, if you dare to make a big statement here, I can let you die without a place to be buried!"

"Whether it's fooling or not, just find someone who knows how to verify it. Yang Kai frowned.

"Good guts!" Yang Zhen sneered and said lightly: "Go and invite Cheng Bailian from the Danfang over." ”

"Oh. A fat elder answered, and his figure disappeared in a flash.

Cheng Bailian, the chief alchemist of the Yang family, is also famous for his attainments in alchemy, but compared with Xiao Fusheng, he is slightly inferior.

Xiao Fusheng is a Xuan-level high-grade alchemist, and there is only one Xuan-level high-grade alchemist in the entire Han Dynasty. And Cheng Bailian is only a Xuan-level middle-grade alchemist.

Although there is only one order missing, it is this level that rests between Cheng Bailian and Xiao Fusheng like a moat, so that he can only look up to the master's back.

"It's too late for you to regret it now, wait until Cheng Bailian comes over and then change your words, and the old man won't condone you. Yang Zhensen drank lightly and made the most difficult temptation.

Yang Kai frowned, and said with a displeased expression: "Elder, I will serve these two sets of spirit arrays, firstly, I want to exchange them for two blood servants to follow, and secondly, I also want to give this thing to the Yang family and bring some benefits to the Yang family, after all, this is the place where I was born, if I just want to exchange for two blood attendants, with the value of this spirit array, only one set is enough, why should I bring two sets? ”

Yang Zhen looked stunned, thought about it carefully, and felt that what Yang Kai said made sense, so he couldn't help but look a little hazy, and nodded: "You're right, maybe the old man is too cautious, but what the truth is, let's wait and see." It can't be fake, it can't be fake, hehe!"

After saying that, he frowned again and carefully examined the two sets of spirit arrays in the jade, but he couldn't see too many famous halls.

It took a full hour before the fat elder who rushed over dragged a man about fifty years old over.

When he entered the Hall of Elders, this person had a gloomy look on his face, and he seemed a little unhappy.

Entering the main hall, without waiting for Yang Zhen to speak, Cheng Bailian shouted angrily: "Yang Zhen, what are you doing? The old man is refining a furnace of Xuanqing Pill, and he is about to open the furnace, you call the old man over at this critical juncture, if you don't compensate me for that furnace of Dan, the old man will not give the Yang family alchemy for three months!"

"Compensation, compensation!" Yang Zhen nodded again and again with a dark face.

Although he was still called by his name in front of him when he was older, and he shouted angrily like this, Yang Zhen couldn't be angry. After all, this person in front of him was the chief alchemist of the Yang family, and many high-quality pills had to be refined by him, so even if there was a huge gap in strength, Yang Zhen had to swallow his anger.

Alchemists, I can't afford to mess with them, especially alchemists with high skills.

Cheng Bailian snorted lightly and said: "That's a furnace of heaven-level high-grade pills, although it is not very valuable, but it also cost me a lot of thought, look at your eyes, 500,000 taels will do." ”

Yang Zhen's face was much darker, and he endured his anger and said in a sullen voice: "Don't talk about this, let's get down to business first." ”

Cheng Bailian nodded, then glanced at Yang Kai, who was standing next to him, and said, "I heard on the way here, are the two sets of spirit arrays that this kid brought back?"

"Yes, you can see if this is really useful. Yang Zhen handed over the two pieces of jade.

Cheng Bailian took it casually and smiled disdainfully: "The old man has been alchemy for so many years, and his attainments in alchemy are not shallow, and he has studied many spirit arrays, but he has never heard of such a magical spirit array in the world. I see that you are getting older and more confused, and you were deceived and dragged the old man into the water, spreading the word that I see where your old face goes. ”

"Don't talk nonsense, take a look first!" Yang Zhen was annoyed by what Cheng Bailian said left and right, but he had nowhere to vent, his old face turned purple, and he secretly decided that if Yang Kai really lied to him, he would definitely not take it lightly.

Cheng Bailian found a place to sit down on the side, with a casual expression, and slightly released his divine sense to probe into the jade.

The people in the entire Hall of Elders, except for Yang Kai, everyone else looked at him with blank eyes, wondering what he would say of these two sets of spirit arrays.

Who knew that Cheng Bailian had just probed his divine sense into it, and suddenly he screamed, and the body that had just sat down stood up suddenly, with an unbelievable expression.

Everyone was holding their breath and waiting nervously, and they couldn't help but be startled when he shouted like this. (To be continued.) If you like this work, you are welcome to vote for recommendation and monthly passes, and your support is my biggest motivation. )
