The two of them finished preparing one after another, and below, tens of thousands of monks stared intently at the two people on the stone platform, and they all made their own guesses.

Jiang Yi and the Dan disciples of Wangxing Pavilion also held their breath, their faces were nervous, although the real competition had not yet begun, but their hearts had already hung in their throats, after all, this bet was too huge, and it involved the Xuandan Furnace.

Lu Chen smiled at Jiang Yi below, signaling him not to worry, he would definitely win the Black Dragon Pill Furnace for him.

Dongfang Yu looked at Lu Chen coldly, his face was full of arrogance and disdain, and said, "Are you ready?"

"Before you come to this holy burning square, you have been prepared. ”

Indeed, before he came, Lu Chen had already planned everything, originally he wanted to refine a four-grade Xuandan, but thinking that Dongfang Yu also had the ability to refine the four-grade Xuandan, although Lu Chen believed that Dongfang Yu had not yet reached the realm of the fourth-grade Xuandan, but thinking that he had refined the third-grade Lingdan, as a second-grade Xuandan, this was enough to prove that this person did have a talent in Danshu.

As a result, although Lu Chen was seventy or eighty percent sure of using the Four-Rank Xuandan to fight Dongfang Yu, he was not 100% successful, so Lu Chen gave up this method of refining the Four-Rank Xuandan.

In recent months, in addition to breaking through the four-grade Xuandan Master, Lu Chen has also been making research on Yidan, and so far, it can be regarded as a small achievement.

Today's Lu Chen can easily refine the second-grade Purple Gold Dragon Pill, coupled with his understanding and control of the dragon's breath, he also has more than eighty percent certainty of refining the third-grade Purple Gold Dragon Pill through the dragon's breath, and the value of the third-grade Alien Pill is definitely more than the fourth-grade Gathering Spirit Pill, so Lu Chen chose the refining of the Purple Gold Dragon Pill.

"That's good. ”

Dongfang Yu responded, a jade-colored token was taken out of his arms, only to see him decisively crush the golden token, and then quickly threw it into the air, in an instant, the wind and clouds in the sky changed color, and in the center of the Holy Burning Square, there was a jade platform that suddenly rose from the ground, connecting with the jade light in the sky.

"Holy Burn, please. ”

"Holy Burning Heavenly Moment?" Lu Chen was stunned for a moment, not understanding what this Dongfang Yu was doing, but at this moment, he found that everything around him had changed wonderfully, he looked around and found that everything around the Holy Burning Square below had slowed down, as if time had slowed down.

Lu Chen didn't know that at this time, the crowd in the Holy Burning Square had exploded, and Lu Chen didn't know it when he first arrived, but the people who had been in this spiritual capital for several years knew what this Holy Burning Heavenly Moment meant.

In addition to being able to gather the momentum of heaven and earth and allow the Dan Master to refine the best elixir, the trial gold plate can also accurately test the value of the elixir, but the most important thing is that the Holy Burning Square has a special ability, which is to open the Holy Burning Heaven Moment.

When the Holy Burning Heaven Moment is opened, the space on the stone platform will be controlled by the jade platform below, and through some kind of anti-heaven ability, the time flow speed in that space will be accelerated.

The time outside has not changed, but the Dan Master inside feels that the time outside has been frozen, and the real situation is that the time flow inside has become faster.

No one knows why it exists, only legends say that this is the one who left the Holy Burning Square and surpassed the existence of the Holy Burning Heaven, and formed this Holy Burning Heavenly Carving.

Later generations often have people who look at the Holy Burning Heavenly Carving in the Holy Burning Square, but all the Dan masters who want to fight this idea have suffered the same result in the end, as if they were cursed, overnight, not only the Dan Technique, but even the cultivation were all abolished, and they became a mortal.

As one of the landmark buildings of the Lingdu, the Holy Burning Square has gradually evolved into the existence of the Holy Land of the Lingdu, he is not only protected by the powerful people hidden in the Lingdu, but also a kind of prohibition itself, no one can break this prohibition, even if there were once powerful people who wanted to remove the entire Holy Burning Square, and finally ended up with a mortal.

But some people say that the Holy Burning Square is actually spiritual, and if someone is fated to come, its prohibition will be broken, and then it will be sought away by this person, but all these are rumors, and no one can say whether it is true or false.

As if everything in heaven and earth had stopped running, Lu Chen was surprised at first, but soon returned to calm.

"I really didn't expect that this Holy Burning Square would have such a miraculous effect. ”

"Hmph, hillbilly. Dongfang Yu snorted disdainfully, and had already begun to prepare for alchemy: "The Holy Burning Heaven Moment has already accelerated the time flow rate of this space by ten times, so we can refine the pill in a short period of time, one point higher." ”

"You're prepared. Lu Chen sighed: "With you, you don't have the ability to open the Holy Burning Heaven Carving, the jade in your hand was given to you by Dongfang Yi? Could it be that he is also afraid." ”

"My grandfather is about to be promoted to a fifth-grade Xuandan master, will he be afraid of you?" Dongfang Yu sneered: "You little miscellaneous fish, I can settle you ten." ”

"Haha, then I want to see if you, a dog wearing a tiger skin, can become a Tibetan mastiff. ”

Although Dongfang Yu didn't understand what the Tibetan mastiff was, he knew it very well, and his face changed in an instant, he glared at Lu Chen, turned around to control the Dan furnace, and began to refine the Dan.

Lu Chen was also not ambiguous, hanging the purple refining furnace above his head, sitting on the stone platform, entering the realm of empty light, and conjuring the phantom of the purple refining furnace in the sea of knowledge, Lu Chen pinched the auspicious time of heaven and earth, and as soon as the auspicious time arrived, he integrated his divine consciousness into the purple refining furnace, turned on the three-flavor true fire, and refined the spirit crystal.

The alchemy of the two officially opened, and there was a layer of mist that enveloped the two of them, and the people outside couldn't see what was going on inside, even though many people had reached out of their divine sense to observe, they still couldn't penetrate that special space, and everything was only known after the two of them became dan.

This time, no one knew what kind of pill Lu Chen and the others were going to refine, nor did they know how long it would take them.

However, no one was willing to leave, because the Holy Burning Heaven Moment had already been opened, and the time flow inside had been accelerated, maybe Nadan would be able to be baked soon, and maybe even if the Holy Burning Heaven Moment was opened, it would take a long time.

"Uncle Shi, what kind of Dan is Master Lu Chen going to refine this time? That Dongfang Yu is the most powerful descendant of Tiandan Mansion, will Master lose?" Next to him, a young man in blue asked Jiang Yi.

This young man's name is Yuan Lin, he is one of the more outstanding disciples recruited by Wangxing Pavilion, Jiang Yi has always been personally training, and Lu Chen will often give him guidance, in just three months, this person's Danshu is about to enter the category of a second-grade spirit pill master, and at this speed, he is about to catch up with Jiang Yi.

However, Jiang Yi also realized the sense of crisis, since the rapid improvement of this group of Dan disciples, he has been breaking through his realm all the time, and he has worked much harder than before.

Yuan Lin is a few years older than Jiang Yi, and his uncle's call always gives Jiang Yi goosebumps.

"Senior brother won't lose. After a few hours, Jiang Yi became calm, he believed that Lu Chen would definitely be able to refine a good pill, defeat Dongfang Yu, and win back a Ding Xuandan furnace for himself.

A few hours have passed outside, and the chatter has not stopped from the beginning to the present, but a few hours outside have passed several days inside.

At this time, Lu Chen had already controlled the three-flavor true fire to refine more than half of the dozens of catties of spirit crystals, he was careful step by step, compared with before, the once stunned Qing was now familiar with the road, he could accurately know the control of the fire, and what to pay attention to at certain moments, and he could roughly calculate the auspicious time, although it could not be regarded as 100% accurate, Dan was much better than back then.

In the blink of an eye, ten days have passed in this space inside, and the spirit crystal has already been thoroughly refined by Lu Chen, and the embryo of the three-grade spirit pill has been formed, refining the three-grade spirit pill is very simple for Lu Chen, so Lu Chen's refining in the first ten days was very smooth.

The time budgeted this time was thirty-seven twenty-one days, and the spirit pill Lu Chen in the first ten days was refining very smoothly, and next, it was time to integrate into the dragon's breath.

He ingested the dragon's breath into the Dan furnace, and in an instant, the entire Dan furnace was filled with a purple-gold aura, inside the Dan furnace, there were countless purple-gold dragon figures circulating around, Lu Chen didn't dare to be careless, carefully controlled every trace of dragon breath, and slowly integrated into the elixir's Dan embryo.

There are two ways to form a dan embryo during alchemy, one is to integrate all the aura to form a dan embryo and refine only one elixir, and the second is to form several dan embryos and then refine several elixirs, which is called a furnace by outsiders.

However, although the number of pills in one furnace is superior, the effect is much worse than one, so if it is not for the auction house transaction, most of the ordinary Dan masters only refine one pill when refining pills.

The Dan embryo was formed, and when it was integrated into the dragon's breath, a little accident occurred.

The first trace of dragon breath was integrated into the Dan embryo, and suddenly there was a crack in the Dan embryo, as if it was about to decompose, Lu Chen was startled, and hurriedly took the dragon breath back, he observed for a while and found that refining the Purple Gold Dragon Pill was not as simple as he imagined.

If you use the spiritual power of the ordinary spirit gathering pill to refine the elixir, there will be a situation where the spiritual power is insufficient to support the foreign body and cause the dan embryo to split, thinking of this, Lu Chen couldn't help but break out in a cold sweat, fortunately he reacted quickly, otherwise he would really have lost his previous efforts.

Lu Chen wiped the beads of sweat from his forehead, and then took out a large piece of spirit crystal from his body and put it into the Dan furnace, starting the second refining.

Lu Chen had encountered this situation before, but it was not as obvious as this time, but alchemy was originally a comprehension while refining, so Lu Chen did not panic, it took a full three days, Lu Chen finally finished refining the second spirit crystal, and next, it was to integrate the spiritual power of this second spirit crystal into the first Dan embryo, which was a test, because Lu Chen had not done anything to fuse two Dan embryos before.
