Lu Chen didn't expect that this piece of stone flower would be called out for a sky-high price of one hundred and twenty catties of spirit crystals, and he always thought that this stone flower was worth twenty or thirty catties, and this number really made Lu Chen's heart become turbulent.

In the crowd, an old man over the age of sixteen came out, he had white hair, his body looked a little rickety, he walked very slowly, and coughed a few times from time to time, as if he would fall down at any time.

He walked out of the crowd tremblingly, took out a storage bag and threw it at Lu Chen, and said in a hoarse voice: "The white jade flower contains a large amount of life essence, which may help the old man prolong his life, one hundred and twenty catties of spirit crystals, worth." ”

Lu Chen took the storage bag, weighed it, smiled, said thank you, and also shot out the stone flower and threw it into the old man's hand.

The old man took the stone flower, carefully put it away, looked at Lu Chen and smiled, turned around, and disappeared from everyone's sight in a few steps.

This kind of old man who is about to enter the earth, his longevity is about to end, and he is trying to prolong his longevity, so he will not miss any thing that contains the essence of life, and there are countless people like this on the Chaos Heaven Continent, even those who are known as the world's strongest people in Tianjiao, they will not escape the end of their lives.

Lu Chen opened the storage bag, then took out a few fist-sized spirit crystals, weighed them, about twenty-three catties, and then took the rest into the train that received the second dantian, stared at Dongfang Yu over there with a smile, and said, "You can start." ”

Dongfang Yu snorted coldly, threw the spirit crystal into the Black Dragon Pill Furnace, and sat on the ground, the Black Dragon Pill Furnace was suspended above his head, the flames were burning, and bursts of charm overflowed from the Dan Furnace.

Lu Chen didn't hesitate, he first quietly used the Hidden Dragon Array to conceal the breath of the Bagua True Furnace, and then after some special transformations, he changed the original appearance of the Bagua True Furnace and sacrificed it from the first dantian.

Lu Chen did this just because he didn't want people to know the value of his Dan furnace, even if it was Lu Chen himself, he couldn't figure out how awesome this Dan furnace was.

The moment the gossip true fire furnace was sacrificed, the people below were all shocked, and they didn't know what kind of transformation Lu Chen had made to this Dan furnace, at this time, it was covered in black paint, as if it was a big iron furnace that had been burned out, and it didn't show any brilliance, but only the three-flavor true fire emitted bursts of golden charm, but under the smear of the appearance of this Dan furnace, even if it was a three-flavor real fire, it was ignored by many people.

Dongfang Yu also smiled disdainfully: "A bad furnace, I dare to refine the three-grade spirit pill." ”

Lu Chen couldn't help but be surprised, the palm-sized Dan furnace rotated in the palm of his hand, and then slowly became larger, rising to the top of Lu Chen's head, the furnace opened, and suddenly a thousand golden lights flashed, shining on the heavens and the earth.

Many people were still in the speechlessness just now, and when the golden light flashed, many people's faces changed, but the spirit crystal was put into the furnace, and soon the lid of the furnace was closed, and the golden light disappeared, and the brows of these people were furrowed again.

Only the little Dao boy, but his face changed suddenly at this moment, and his eyes kept focusing on Lu Chen's gossip true furnace, as if he had seen something.

At the beginning of the alchemy, the two of them controlled the Dan furnace respectively, sitting cross-legged on the stone platform, the two closed their eyes tightly, and bursts of divine power shot out from their bodies, enveloping the Dan furnace.

The Dan furnace hovered above the heads of the two people, accompanied by the expansion and contraction of divine power, and the flames in the lower Dan furnace were sometimes large and sometimes small, sometimes weak and sometimes prosperous.

From the outside, there was not the slightest difference between the two, but everyone knew that they had actually already invested in the fierce alchemy process.

Danshi and Dan Furnace have generally passed the fusion of divine souls, at this time, the phantom of Dan Furnace has been conjured in the sea of Dan Shi's consciousness, and Dan Shi's divine consciousness is also thrown into the sea of knowledge, alchemy, mental control is actually the essence, as for the appearance, only at the moment of Dan Cheng can flash.

In the sea of consciousness, Lu Chen's divine sense was formed, and his divine form turned into a streamer of light and flew directly into the Dan furnace.

The secret texts of the Danshu inside the Dan furnace had already appeared in front of Lu Chen's eyes, but most of them were ancient texts that Lu Chen couldn't understand, and less than one-third of the Danshu texts that had been cracked by the Taixuan Heavenly Master of the Tushi Palace, and the secret text of the Danshu about the Sanpin Gathering Spirit Pill had been completely deciphered by him.

This technique is called "Gathering Spirit Secret Technique", which can be included in the Bagua True Fire Furnace, and it can definitely be regarded as the top alchemy secret technique, through the records inside, Lu Chen carefully operated, with the experience of the previous failures, Lu Chen knew how important it was to control the fire, grasp the time and the urging of the peripheral divine power.

He walked on thin ice with every step, and he seemed to be extra careful.

Under the burning of the three-flavor true fire, there are countless golden halos flowing into the upper layer of the Dan furnace, and the spiritual energy overflowing from the spirit crystal is mixed and combined, the three-flavor true fire is known as the top foreign fire in alchemy, and the refined spirit pill has the effect of getting twice the result with half the effort.

Time passed minute by minute, and although the two of them seemed motionless on the outside, in their sea of knowledge, minutes were like walking on the tip of a needle, tensing their nerves to the extreme.

A few hours later, the elixir embryo in the Dan furnace had been formed, and more than 20 catties of spirit crystals had also completely melted, and the inside of the Dan furnace was full of spiritual energy, and countless silver dragon shadows were circulating everywhere inside.

Lu Chen carefully urged every dragon shadow inside, carefully penetrated into the Dan embryo, and then controlled the three flavors of true fire, and used the true fire golden rhyme to continue to integrate, sometimes nervous, sometimes relaxed.

Alchemy, for onlookers, is a boring and extremely time-consuming process, refining the elixir is less than forty-nine hours, more than forty-nine days, and some more than four grades of Xuandan, a refining is several months, legend has it that the holy pill needs to be refined for a year or even many years.

Although Lu Chen and the others practiced the three-grade spirit pill, they both unanimously chose the shortest time to practice, even if this was the case, it would take at least forty-nine hours.

It's been a long time of torment and waiting, many of the viewers watching below have left after a few hours, and then new viewers have arrived, and then left, in short, there has never been a shortage of spectators in this holy burning square, but they won't stay too long, everyone has made this decision, and when the elixir is released, let's see what happens.

Only Dao Tong has been staying here, he seems to be even more nervous than Lu Chen, for forty-nine hours, his brows have been furrowed, and his heart is also hanging in the air, for fear that Lu Chen will make any mistakes.

Seven seven forty-nine hours have arrived, at this time on the Holy Burning Square, has been full of onlookers, looking around, there are a sea of people, there are tens of thousands of people, Lu Chen and Dongfang Yu are still sitting on the stone platform, the Dan furnace above the head began to overflow, especially Dongfang Yu's side, it is even more emancipated.

I saw Dongfang Yu open his eyes violently, a trace of excitement appeared on his face, he got up suddenly, and two special charms flew out of his sea of consciousness, and quickly sank into the black dragon pill furnace above his head.

In an instant, the Dan furnace opened, and thousands of lights flashed, and countless fragrances overflowed, filling the entire Holy Burning Square.

"Three-grade spirit pill, Dongfang Yu actually refined the third-grade spirit pill with the realm of a second-grade spirit pill master, it's really incredible. ”

"It is worthy of being the grandson of the four-grade Xuandan master Dongfang Yi, and he is indeed an alchemy genius, with such a terrifying comprehension ability, his future achievements are definitely even more amazing than his grandfather Dongfang Yi. ”

The elixir was completed, Dongfang Yu's face showed a strong look of pride, he flew down from the stone platform, the black dragon furnace began to become smaller, circulating in his palm, the golden light flashed, and a crystal clear elixir appeared between his palms.

He strode towards the trial gold plate over there, threw the elixir in his hand, and in an instant, golden light overflowed, and a pillar of light rushed out, more than twenty meters high.

"It's really a three-grade elixir, and it's the kind that contains extremely full spiritual power. There was an exclamation from the side, and many people's eyes widened and horror was written.

Dongfang Yu smiled, turned to stare at Lu Chen over there, and said with a smile: "Boy, the time is coming, have you finished refining?"

At this time, Lu Chen had already walked out of the sea of knowledge, and the embryo of the three-grade elixir had been completely condensed and formed in its sea of knowledge, and what was needed now was to beat the elixir in the sea of consciousness into the elixir of reality.

There were also two golden charms that shot out from Lu Chen's sea of knowledge, and then diffused into the gossip true furnace.

At this moment, everyone looked at Lu Chen's side, many people were looking forward to what kind of elixir Lu Chen could refine, among them, the most nervous was the young Dao Tong, after dozens of hours, Dao Tong barely closed his eyes, at this time he was already tired, and his eyes were full of bloodshots.

"God bless the son, you must refine a good pill. The boy put his hands to his lips, and had prayed this prayer at least a hundred times from the beginning to the present.

Finally, Lu Chen's tightly closed eyes opened suddenly, and seeing the crowd of people below, he was not in a hurry at all, he took back the Dan furnace, flew off the stage, and walked towards the trial gold plate over there step by step.

"Boy, don't pretend, what about the pill you refined? ”

"Hmph, wait, I'll take it out and scare you to death. Lu Chen glared at Dongfang Yu, walked to the trial gold plate, the Dan furnace opened, and the golden light did not overflow as expected, and the faces of many people present changed, and the Taoist boy was even more pale: "Childe"

"What are you?"

Dongfang Yu laughed, and when he saw Lu Chen take out a black thing from the Dan furnace, he pointed at Lu Chen and teased loudly: "Is this what you pulled out?"

Beside him, there were also many people laughing, Lu Chen was also stunned, it seemed that he didn't expect such a result, the alchemy actually failed, Lu Chen also felt very incredible, he was obviously very cautious in every step, until the final baking, he didn't feel any abnormality, but why, but he refined this kind of thing? .
