Back in the courtyard, Zhan Chen entered the cultivation room again, took out the "Yuzhai Alchemy Primary", and looked at it with a lot of emotion. At the beginning, he obtained it from the True Martial Secret Realm, and he originally thought that it was something of no use to him, but he didn't expect that now it has become the one he relies on the most.

Moreover, he also had a deep sense of crisis, because the pills recorded in this alchemy book were at most the seventh grade of the first rank, and there was only one kind of seven-grade pill, which was a wood-attribute pill named Chunxiao Rongxing Dan, which was also inconsistent with his metallicness.

Fortunately, the sixth-grade top-level pills have Qianqiong Bailu Dan, and the sixth-grade high-grade pills are beneficial to the Yuansheng Essence Pill, both of which can be used by full-attribute martial artists, but correspondingly, their improvement effect on cultivation is naturally three percent lower than that of the exclusive attribute pills.

Zhan Chen couldn't help but smile bitterly, how could he have thought in the past that what he lacked most now was not the elixir, but the pill formula.

He looked at the column of sixth-grade high-grade pills, and now there are fewer and fewer pills available for his own refining, and there are only three sixth-grade high-grade pills: the Great Sun Golden Eye Pill with fire attributes, the Three Thunder Juding Pills with thunder attributes, and the Yiyuan Shengjing Pill.

He immediately decided to refine the Great Sun Golden Eye Pill. The reason why he chose this elixir was because he happened to have a lot of elixirs on hand to refine it, and the elixir for refining this elixir was also the easiest to buy.

Refining the Great Sun Golden Eye Pill already requires the use of seventh-grade elixirs, and one use is two plants, plus dozens of auxiliary medicines, the cost of refining once is more than two thousand high-grade Yuan Stones! Moreover, refining sixth-grade high-grade elixirs will inevitably fail, and such losses will be even greater, so he must try to increase his success rate as much as possible.

Zhan Chen burned incense and bathed, adjusted his breath, and adjusted his state to the best, then he took out the Nine Turns Flame Phoenix Furnace, communicated with Huang'er with his divine sense, and said, "Huang'er, let's start!"

"Yes—master!" replied the machine spirit.

Zhan Chen shook his head, helpless, with the improvement of his cultivation, his control of the Dan Furnace became more and more proficient, but it was a pity that Huang'er's spiritual intelligence had not been improved, which was also a major factor restricting his refining of high-grade pills.

Cutting off his thoughts, he ignited the Nirvana Divine Flame according to his habit, and controlled the size of the firepower, and put the seven-grade elixir into the furnace first to slowly temper it, the problem came immediately, Zhan Chen found that the difficulty of refining the seven-grade elixir was much higher than that of the sixth-grade elixir.

Gradually, he felt that his true yuan was passing rapidly, and hurriedly stuffed the prepared elixir to restore the true yuan into his mouth.

Suddenly, Zhan Chen's spirit moved, communicated with Huang'er, and said, "Huang'er, can you adjust the firepower of the Nirvana Divine Flame a little more?"

Asking Huang'er to cooperate in alchemy, this was definitely a bold attempt! He had never thought of it before, but today's challenge to the sixth-grade high-grade elixir forced him to innovate, and he was even ready to waste a medicinal material.

"Master—how much should you turn it up?"

"You think about it, it's big enough to smelt this elixir essence out!" Zhan Chen tried to order, and to be honest, he didn't know what the result would be.

"Okay—right!" replied Huang'er.

Then, Zhan Chen saw the Nirvana Divine Flame throb, it seemed to increase a few points, he tried to let go of the control of the True Yuan a little, and was pleasantly surprised to find that Huang'er did a good job.

A fine light flashed in Zhan Chen's eyes, if Huang'er could assist him in refining the pill, then there was no doubt that his pressure would be reduced a lot, and it would be possible to refine a higher pill!

You must know that in the process of refining the elixir, the process of refining the elixir and the condensing pill is the most consuming true element, if you can save the true yuan in refining the elixir, then it means that you will have more true yuan to condense the pill, so that the success rate of the condensing pill will be greatly improved.

With Huang'er's assistance, Zhan Chen's refining speed was undoubtedly greatly accelerated, and even in most cases, Zhan Chen let Huang'er try boldly by herself, and only when she made a mistake, she would use her true yuan to interfere, so that Zhan Chen's true yuan was not only consumed, but also gradually returned to the peak with the help of the recovery of the true yuan elixir!

Soon, dozens of medicines were quenched by Huang'er, and in the Dan furnace, a fiery red viscous liquid was beating, like the reflection of the morning sun in the water, full of vitality and vitality.

Seeing this, Zhan Chen was overjoyed, hurriedly concentrated, and quickly pinched out the eighteen seals of Ning Dan, every time he came to this step in the past, he would always have a weak follow-up, and he had to rely on gnawing on the pill to barely support.

But this time, this phenomenon did not happen, and he successfully completed this series of seals and beat them into the Dan furnace.

When he did all this, Zhan Chen breathed a sigh of relief, knowing that he had basically succeeded, but he didn't dare to take it lightly, and continued to use his true yuan to carefully ponder and nurture the elixir, just like a loving mother caring for the baby in her arms.

For three days and three nights, he maintained the input of the True Yuan, and on the morning of the fourth day, with the newborn rising sun, the Nine Turns Yanhuang Furnace also moved.

Zhan Chen hurriedly opened the lid of the furnace, and a bright red pill as blood jumped out, emitting a brilliant golden light, which reflected with the rising sun, like another small sun, and like a golden eye, and in the outermost layer of its golden light, it also refracted the nine-colored pill halo, indicating that its identity was the nine-turn golden pill.

At this moment, Zhan Chen's heart was inexplicably excited, and he didn't understand why, he was originally used to seeing the Nine Turns Golden Pill, and it was normal for him to be extremely calm at this time.

The Great Sun Golden Eye Pill was full of spirituality, as if it was about to get out of the air, Zhan Chen hurriedly grabbed it and stuffed it into the jade bottle.

Staring at the jade bottle, his eyes were full of hope, and he muttered, "Here are 10,000 high-grade Yuan stones!"

After recovering a little, Zhan Chen threw himself into the refining of the second Great Sun Golden Eye Pill non-stop, but this time, he fell short because a Ning Dan Seal was never well controlled.

Undeterred, he immediately refined the third elixir......

Before I knew it, a month had passed, and Zhan Chen had successfully refined a total of three Big-Eyed Golden Eye Pills and one Three-Thunder Gathering Pill, all of which were Nine-Turn Golden Pills.

By refining these pills, Zhan Chen also roughly felt that his current success rate of refining sixth-grade high-grade pills was fifty percent, which was still achieved with the help of Huang'er, otherwise it would probably be less than thirty percent.

"Fifty percent of the success rate should be satisfied, you know, this is still the success rate of refining pills that exceed my normal alchemy ability, and the success rate of ordinary alchemists is probably around thirty percent, it is precisely the existence of a failure rate within that the value of the pill will be so high. Zhan Chen quickly figured it out.

With the refined elixir, Zhan Chen hurriedly set out on the road, he was going to the Hongyun Auction House, because the auction was going to start tomorrow, and he hadn't registered his auction items yet.

When he got there, Zhan Chen came to the window, immediately showed his VIP card, and said to the little student inside: "I want to register the auction items." ”

Xiao Sheng looked at the jade plate and said: "Senior, you are a VIP card, you can go to the VIP room to register, there is the best service." ”

"Does the VIP room mean on the stairs opposite?"

"Not bad. ”

"Okay!" Zhan Chen immediately turned around, walked up the narrow staircase on the opposite side, and came to the VIP room again.

He was greeted by a beautiful female guest, who stepped forward and asked, "Senior, do you need anything?"

"I want to register the lot. ”

"What are you going to auction?"

"I'm going to auction off the pill. ”

"What grade of elixir?"

"It's a sixth-grade high-grade elixir. ”

"Okay, please, I'll go and ask our appraiser to come over. ”

After the female guest finished speaking, she went out, and Shaoqing brought back an old man with white hair and beard, who had the cultivation of the Great Perfection of the Martial King.

As soon as he saw Zhan Chen, he asked, "Bring me your elixir." ”

Zhan Chen took out four jade bottles and placed them on the table.

The old man picked up one of the bottles at random, opened the lid, and a strong medicinal fragrance erupted, filling the room in an instant.

Before seeing the elixir, he smelled the fragrance of the medicine first, and he couldn't help but praise: "Good medicine!"

Then he took out the vermilion pill in it and looked at it, and he was stunned on the spot, and then his face showed a look of disbelief, and he muttered: "This is - Nine Turns Golden Pill!"

It was the first time that the female guest beside her saw the old appraiser's reaction so big, and asked with concern, "Mu Lao, are you okay?"

The old man reacted at this time, but his eyes staring at this elixir could not be removed.

The female guest couldn't help but ask again: "Mu Lao, is this elixir very precious?"

She didn't understand why Mu Laodu, who had seen the world, would pay so much attention to this sixth-grade high-grade elixir.

Mu Lao sighed: "Xiao Xia, you don't understand, this is the Nine Turns Golden Pill. ”

"Is the Nine Turns Golden Pill rare?"

"Of course it's rare, this is the highest quality golden pill, it only exists in legends, the old man has lived for more than a thousand years, he has walked countless places, and he has seen countless pills, but those pills are only five turns at most. But do you know? Today, I saw the Nine Turns Golden Pill! This quality of the pill could only exist in the kind of large sect of the Ten Thousand Laws Continent. ”

"Every time the pill increases, the quality will increase by one level, and when it reaches the ninth turn, it is the number of the Great Perfection, and the medicinal power will be doubled, so the value of this pill is equivalent to the top level of the six-rank pill. No, it is easier to be absorbed by martial artists than ordinary sixth-grade top-level pills, and the medicinal power is more durable and long-lasting, and the help to martial artists in the realm of martial kings is tantamount to a seventh-grade first-rank elixir!"

Xiao Xia was also stunned, she didn't expect Mu Lao's evaluation of this little pill to be so high!

Zhan Chen sat comfortably on the side, listening to the conversation between these two people, extremely contented, after all, the elixir he had worked so hard to refine could be affirmed by the appraiser, what a happy thing it was to see at first sight.

Seeing that Na Mu Lao was so surprised, he decided to order some more "fierce medicine", so he said to him: "Senior, take a look, the other three bottles are also filled with this kind of Nine Turns Golden Pill. ”

"What did you say?!" Mu Lao was startled, and both eyeballs were about to shoot out.
