Using true energy to carve traces in some jade to convey some information that is inconvenient to express in words is not a very powerful method, but only strict control of true energy is required.

So when Yang Zhen saw Yang Kai take out two pieces of jade, he knew that there must be some reputation inside.

The spiritual sense penetrated it and carefully investigated it.

Suddenly, Yang Zhen frowned and his eyes became solemn. After a moment, his eyes were full of doubt, and he became surprised and astonished again.

As his eyes changed, the expression on Yang Zhen's face was also extremely exciting.

The old men who were originally going to watch the show couldn't help but be stunned when they saw Yang Zhen's expression, and wondered in their hearts whether he had discovered something amazing.

After a while, Yang Zhen took a deep breath and slowly retracted his spiritual sense that had penetrated into the jade. He looked at Yang Kai with a strange look and squeezed another piece of jade with a serious expression.

As I continued to investigate just now, as if the incident was played back, the various expression changes on Yang Zhen’s face were interpreted again.

At this moment, the white-haired elders in the hall couldn't sit still. They stood up at any time and gathered quietly towards this side.

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

"What's inside?" An elder couldn't help but wonder what Yang Kai brought to him that Yang Zhen could pay so much attention. While speaking, he reached out to get the piece of jade placed on the table.

Before he got it, Yang Zhen caught him back, which made the other party glar at him.

"Come here for me!" Yang Zhen waved his hand and pushed the elders who were protruding their heads aside without hesitation.

"Disciple is here." Yang Kai stepped forward. To count it, Yang Zhen should be a person of his grandfather, but in the Yang family, he is generally not called by kinship, unless they have a good relationship with each other.

Holding 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 performed so wonderfully?" A white-haired elder was extremely shocked, and the others shook their heads slowly, and their expectations suddenly decreased a lot.

"Two sets of spiritual arrays."

"Nonsense." Yang Zhen shouted lightly, "I'm not a fool. Of course I know it's two sets of spiritual arrays. What I asked was what the spiritual array was used for."

As he spoke, his old face turned redder.

He is very old and has a lot of experience. At this moment, he can't even identify the things that a young man from his grandchildren gets back, which naturally feels a little embarrassed.

Yang Kai pinched his nose: "The spiritual array for alchemy!"

Yang Zhen was stunned: "Is it for alchemy?"

As he spoke, he kept shaking his head and said, "I have seen many spiritual arrays for alchemy. But there has never been any spiritual array as complex and complex as you have brought. Such a spiritual array is a very troublesome thing to portray on the alchemy furnace. If it is used to refine alchemy, it will inevitably consume more energy and true energy of the alchemist. Are you sure these two sets of spiritual arrays are useful?"

"Sure!"

"Let's tell me, what are they used for?" Yang Zhen frowned. He didn't know much about alchemy, so he naturally couldn't see the magic and mystery contained in the spiritual array. He just subconsciously felt that these two sets of spiritual arrays were too complicated and secrets. Although they must be good things, they definitely had disadvantages.

"One of them can improve the success rate of alchemy." Yang Kai introduced in a plain expression, "In other words, if an alchemist's chance of becoming an alchemy is only 60%, then with this set of spiritual arrays, it can reach 90%!"

Yang Zhen couldn't help but be moved.

Ninety percent! Even if he doesn't know how to refine alchemy, he knows how outstanding an alchemist who can guarantee a 90% elixir rate is. Ordinary alchemists can only guarantee a elixir rate of 60% elixir rate. Ten pieces of alchemist materials can only produce six or seven pills.

The better alchemist is about 80%. Most of the disciples from the Xiang Yaowang Valley are at this level. But now, a spiritual array can increase the success rate by 30%. Doesn’t this mean that as long as a slightly better alchemist uses this spiritual array, he can ensure that the alchemist is 100% successful?

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

In an instant, Yang Zhen realized the preciousness of this spiritual array.

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

"What about the other set?" Yang Zhen pressed the shock in his heart and tried to ask in a calm tone.

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

"What does it mean?" Yang Zhen jumped subconsciously and asked hurriedly, holding his breath. If his understanding was correct, then the value of this set of spiritual arrays was even greater than the set just now!

"Originally, when you refine a furnace of mid-grade elixirs in the Heavenly Level and use this spiritual array, there will be some chances of high-grade elixirs appearing at the Heavenly Level." Yang Kai explained patiently and added: "This probability is not very high, but it will always appear!"

The elders' breathing suddenly became rapid, and they also saw the value of this spiritual array.

One of them asked a little nervously: "What if it was to refine a furnace of Xuan-level top-grade pill?"

Yang Kai shrugged his shoulders and smiled, "Maybe there will be spiritual-level pills."

Spirit level! These two words are like war drums pounding in their ears, which made the eardrums of several elders tremble. They all looked at Yang Kai incredibly, trying to see from his face if there were any signs of joking.

Yang Kai responded calmly!

These two sets of spiritual arrays were all learned from the true alchemy techniques, and it is obviously impossible to be useless.

The entire Elders' Hall was silent in an instant, and a group of old guys stood there in a daze, not knowing what to do. They were all thinking about the value of the spiritual array and the authenticity of Yang Kai's words.

After a while, Yang Zhen suddenly came to his senses, looked at Yang Kai with a stern look, and said coldly: "Do you know what kind of guilt it is to fool the Elder Palace? Even if you are a direct descendant of the Yang family, if you dare to speak out here, I can still let you die without a place to die!"

"Are you fooling me? Just find someone who knows what you know to verify?" Yang Kai frowned.

"The courage is good!" Yang Zhen sneered and shouted softly: "Come Cheng Bailian from the alchemy room here."

"Oh." A fat elder responded, and his body disappeared in a flash.

Cheng Bailian, the chief alchemist of the Yang family! His attainments in alchemy are also famous all over the world, but compared with Xiao Fusheng, he is slightly inferior.

Xiao Fusheng is a top-grade Xuan-level alchemist, the only one in the entire man is the top-grade Xuan-level alchemist. Cheng Bailian is only a middle-grade Xuan-level alchemist.

Although it is only one level away, it is this level, like a natural barrier between Cheng Bailian and Xiao Fusheng, making him look up to the master's confrontation.

"You still have time to regret it now. When Cheng Bailian comes to change his words, I will not indulge you." Yang Zhensenran shouted lightly and made the final test.

Yang Kai frowned and said unhappy: "Elder, I will serve these two sets of spiritual formations. First, I want to exchange for two blood servants to follow, and second, I also want to hand over this thing to the Yang family to bring some benefits to the Yang family. After all, this is the place where I gave birth to me. If I just want to exchange two blood servants, with the value of this spiritual formation, only one set is enough. Why should I get two sets? I believe the elder can tell whether it is true or false."

Yang Zhen looked stunned. After thinking about it carefully, he felt that what Yang Kai said made sense. He couldn't help but look a little ugly and nodded, "You are right. Maybe I'm too cautious, but let's wait for the truth. It's not true or false, hehe!"

After saying that, he frowned and carefully looked at the two sets of spiritual arrays in the jade, but after looking at them, he could not see too many names.

It took an hour before and after that the fat elder who rushed over brought a man in his fifties.

When entering the Elders' Hall, this person looked gloomy and looked a little unhappy.

After entering the hall, Cheng Bailian shouted angrily: "Yang Zhen! What are you doing? I am refining a furnace of Xuanqing Pills, and it is about to be opened. You call me at this critical moment. If you don't compensate me for that furnace, I will not refine the Yang family for three months!"

"Pay, compensation!" Yang Zhen nodded repeatedly with a dark face.

Although he was old and was called in person, and even shouted in anger, Yang Zhen could not be angry. After all, the chief alchemist of the Yang family was the chief alchemist, and he had to refine many high-quality elixirs, so even if the strength gap was huge, Yang Zhen had to swallow his anger.

Alchemist, you can't afford to offend, especially those with high abilities.

Cheng Bailian then snorted and said, "That's a furnace of heaven-level top-grade pills. Although it's not very expensive, it also cost me a lot of thought. If you like it, just 500,000 taels."

Yang Zhen's face turned darker, and he suppressed his anger and said in a muffled voice: "If you don't talk about this, just talk about the serious matter first."

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

"Yes, let's see if this is really useful." Yang Zhen handed over two pieces of jade.

Cheng Bailian took it casually and smiled contemptuously: "I have been practicing alchemy for so many years. I have asked myself that my attainment in alchemy is quite good. I have studied a lot of spiritual arrays, but I have never heard of such a magical spiritual array in the world. I think you are getting more and more confused as you get cheated. I'll drag you into the water and spread it out. I'll see where your old face is."

"Stop talking nonsense, take a look first!" Yang Zhen was so angry that he was talking on the left and right, but he had nowhere to vent his face. He was so nervous that his face turned purple that he secretly decided that if Yang Kai really lied to him, he would never go around.

Only then did Cheng Bailian find a place to sit down casually, with a casual expression, and slightly released his spiritual sense and explored it into the jade.

Except for Yang Kai, the people in the entire Elder Palace were all staring at him, wanting to know how he would evaluate these two sets of spiritual formations.

However, Cheng Bailian had just entered his spiritual sense and suddenly screamed strangely. His body, which had just sat down, suddenly stood up again, looking incredible.
