The outside world is still crowded with people, and the discussion has not stopped from the beginning to the present, and soon, the time of a stick of incense has passed in the outside world, but inside the Holy Burning Heaven Carving, ten days have passed.

What Lu Chen wants to refine this time is the Five-Grade Life Essence Pill, but it will take a long time, according to what the Danzu Divine Soul said, if this Pill is to be completely refined, it will take at least a year.

One year's time is just the limit time that the Holy Burning Heaven can evolve, although Dongfang Yi over there wants to refine a fourth-grade pill, but it may also take a lot of time, after all, he has just entered the ranks of the fifth-grade Xuandan masters, and it is also very difficult to refine this pill.

In Dongfang Yi's opinion, Lu Chen can refine a fourth-grade Xuandan at most, even if he refines a fifth-grade Xuandan, he is also determined by Lu Chen, from the hotness in his eyes when he looks at the gossip true furnace, it can be seen that Lu Chen's tripod gossip true furnace is already in his bag, but the real situation, will this be the case?

In ten days, Lu Chen only refined about three hundred catties of spirit crystals, even if he just refined a five-grade Xuandan, he also needed to refine thousands of catties or even thousands of catties of spirit crystals, and refining spirit crystals was only fundamental, the most important thing was the process of integrating the life essence after the Dan embryo was first formed, it was a rather complicated and difficult process, even with the help of the remnant soul of Danzu, it was also quite difficult.

Within the sea of knowledge, the Danzu Divine Soul is divided into three, respectively controlling the refining of the Sanding Dan Furnace, the Sanding Dan Furnace refines three Dan embryos at the same time, and then fuses through the top main furnace, before the fusion, a part of the life essence must be refined into it, and a uniform effect has been achieved.

Lu Chen sat on the stone platform, at this time, he had completely withdrawn his divine consciousness from the sea of consciousness, and concentrated on controlling the heat of the outside world, although this was not as troublesome as the spiritual control in the sea of knowledge, but the first time to refine such an anti-heaven elixir, Lu Chen really felt that it was not easy.

Sweat has wet his clothes countless times, and then it has dried automatically, back and forth countless times, for three months, Lu Chen has been tense almost every second, carefully controlling the peripheral heat.

Whenever an auspicious time appeared, Lu Chen would adjust his strength, and then enter his divine consciousness into his sea of consciousness, informing Danzu to take important steps.

Three months later, the embryo of the Sanding Dan Furnace had been initially formed, and countless jade lights flashed out from the Sanding Dan Furnace, illuminating the entire space with jade light, and countless fragrances attacked, making Lu Chen, who was originally exhausted, suddenly feel a lot more energetic.

"Ziwei Ji is about to appear, Lu Chen, quickly take out a stone flower and prepare. ”

In the Dan furnace, the eager voice of the remnant soul of Danzu sounded, Lu Chen did not hesitate, and quickly took out a stone flower, the stone flower was suspended in Lu Chen's palm, countless life essences flashed, Lu Chen only felt that every cell in his body was full of vitality, and his divine consciousness was even clearer.

At this time, Lu Chen can be said to be seeing six ways and listening to all directions, he quietly sensed the hours around him, and in an instant, a purple light burst out from the soles of Lu Chen's feet, his eyebrows moved, and he immediately threw the stone flower into the purple refining furnace.

"Master, Ziwei Ji is here. ”

"Yes. Danzu responded, and hurriedly concentrated his divine soul in the purple refining furnace, he controlled the stone flower, carefully refined it, and then separated the life essence contained in it, and slowly entered the Dan embryo.

"What time is the Black Dragon Heavenly Hour?"

Lu Chen was stunned for a moment and replied, "In another thirty-three days, but Master, the Black Dragon Heavenly Time is not an auspicious time, and it is very likely to be a fierce time." ”

"You're wrong. Danzu replied: "Your Black Dragon Pill Furnace is closely related to the Black Dragon Heavenly Time, if I guessed correctly, the person who built the Black Dragon Pill Furnace must have chosen the Black Dragon Heavenly Time when he successfully sacrificed the furnace, although the Black Dragon Heavenly Time is considered to be ordinary or even fierce, but in this Black Dragon Pill Furnace, it can be turned into an auspicious time." ”

Sure enough, thirty-three days later, the Black Dragon Heavenly Time arrived as expected by Lu Chen and the others, and according to Danzu's instructions, Lu Chen put some heavenly material spirit treasures containing life essence into it.

At this time, the Dan embryo in the purple refining furnace had been initially integrated into the life essence successfully, and Danzu immediately integrated all the spiritual power into the Black Dragon Dan Furnace.

Whenever the Dan embryo can't withstand the energy of the three flavors of the true fire, Danzu will take out the star spring and integrate it into the Dan embryo, and the outside world, Lu Chen is also watered with the star spring at the same time, and every time the Dan embryo endurance reaches the limit, the star spring will quickly cool its internal power, expand the space, and then continue to integrate.

Three black dragon shadows roared out of the air, all shot into the black dragon pill furnace, Danzu controlled the Dan embryo with his left hand, and conjured up those heavenly material spirit treasures containing life essence with his right hand, and let the three dragon shadows go straight down, his figure never wavered.

"When the black dragon is in the sky, receive. ”

With a loud shout, three dragon shadows rushed into Danzu's body at the same time, and in an instant, his body began to change rapidly, giving birth to dragon claws and dragon scales, and the whole person seemed to have transformed into a real dragon.

"It's not good, the Black Dragon Heavenly Time is really a big murder moment. "In an instant, the three dragon shadows actually controlled Danzu's body, and his whole person became quite painful, and his soul was fighting fiercely with the three dragon shadows.

The Black Dragon Dan Furnace began to shake violently, and countless strange lights shot out from the Dan Furnace, as if the entire Dan Furnace was about to burst open.

"Master, are you okay?" Seeing the accident, Lu Chen's heart also hung in an instant.

"Lu Chen, quickly take out the dragon's breath and use the dragon to defeat the dragon. ”

Danzu's voice gradually became weak, Lu Chen was so anxious that he was sweating profusely, hurriedly urged the black sword, and forcibly took out a trace of dragon breath from the second dantian, just wanted to ingest the second silk, but found that the chaos origin in his second dantian was automatically closed, no matter how hard Lu Chen tried, he could no longer take out half a trace of dragon breath.

"Damn, this decaying dragon is so picky. ”

Lu Chen scolded and threw the only trace of dragon breath into the Black Dragon Dan Furnace, and in an instant, two deafening dragon groans came from the Dan Furnace, and then, three embarrassed black dragon shadows rushed out of the Dan Furnace, but were forcibly forced out by a purple gold dragon.

"Black dragon day, out. ”

With another loud shout, countless purple-gold lights mixed with black light and jade light rushed out, and the Black Dragon Pill Furnace shook from side to side above Lu Chen's head, and this abnormal movement lasted for nearly a day.

Within this day, Lu Chen clenched his toes all the time, he knew very well in his heart that there was a problem when he integrated into the second Dan embryo, they underestimated the ferocity of the Black Dragon Heaven, if it weren't for the help of the dragon's breath, now this Life Essence Pill might have been scrapped.

But fortunately, in the end, Danzu still succeeded in restraining the Black Dragon Heavenly Stone, and integrated that large number of materials into the Dan embryo, until this time, nearly three months had passed, and next, a crucial step appeared.

Integrating the life essence into the Dan embryo in the main Dan furnace is a crucial step, and if there is a slight mistake, the whole process will be wasted.

The main Dan embryo has always been refined by the Bagua True Fire Furnace, and similarly, to integrate into the Bagua True Fire Furnace, the Dan embryo also needs to choose an auspicious time, and according to the joint inference of Lu Chen and Danzu, it was found that the best time to integrate the life essence into the main Dan embryo was the auspicious time of the Great Xuanguang after ninety-nine days.

This is the best time of the year, as soon as the great Xuanguang arrives, the five elements of Yin and Yang and Dingguang, this moment is integrated into the main Dan Dan embryo, which is the best time to choose.

Half a day has passed in the outside world, and in the Holy Burning Heaven, seven months have passed, and the auspicious time of the Great Xuan Guang has arrived as scheduled, at this time, the three Dan embryos have been roughly refined by Lu Chen and the others, and only the life essence that is finally integrated into the main Dan embryo remains, and when the three embryos are completed, it is the final step to integrate the three embryos with the main furnace.

Compared with the previous Black Dragon Ji Shi, the refining of the Great Xuanguang Ji Shi was much smoother, and the two of them cooperated inside and out, and it took seven seven and forty-nine days to finally successfully integrate the life essence into the main Dan embryo, at this time, nearly eight months have passed, and the last four months are the time to fuse the three Dan embryos into one.

At this time, Dongfang Yi's side has also progressed to the end stage, he has also refined three Dan embryos, with Dongfang Yi as the center of the circle, in the surrounding space, there will often be the roar of strange beasts, and there will often be red weird light shooting out, giving people a thrilling feeling, no one knows what Dan Dongfang Yi is refining, only at the moment of Dan Cheng, the truth will be revealed.

In the Holy Burning Moment, a year passed in a hurry, for ordinary people, a year may be just a number, but for Lu Chen, in this year, he barely relaxed for a second, and now after a year, his whole person seems to be much thinner and haggard.

It's been a year inside, and it's only been a day outside.

In this competition, almost everyone stood from beginning to end, and no one left halfway, even if Zhang Lie, who had always been impatient, stood here for a whole day.

In the sky, suddenly a unicorn roar came, and within the Holy Burning Heaven Moment, Dongfang Yi's black hair actually turned gray, and his whole person seemed to be ten years old, and he slowly walked out of the Holy Burning Heaven Moment.

In his hand, there was a blood-red elixir floating, even if it was thousands of miles away, it could make people feel a terrifying feeling.

"Dongfang Yi's Dan has been refined, what kind of Dan is he refined, why does it look so weird?"

"It seems to be a different pill, what kind of foreign pill is it, why do I feel such a violent energy?"

Countless discussions sounded, but Dongfang Yu and his party, who had been watching the battle from the side, showed a look of joy: "Grandpa succeeded, he really succeeded, the four-grade pill, the unicorn beast blood pill." ”
