After the robbery grass was thrown into the Nine Dragons Pearl, as the furnace fire continued to heat up, there began to be a sound like thunder inside, and the frequency continued to rise with time, every time the sound was made, the entire Dan furnace would be shaken, and this sound and frequency began to become faster and faster.

Lou Yi walked quickly around the Nine Dragons Zhuzhu, concentrating and calming his self, concentrating all his spiritual power on the Dan furnace, he stretched out his palm, and hit the Dan furnace with a bang, and the Dan furnace then shook violently, and the true yuan accompanied the sound into the Dan furnace, scattering the rushing grass that was churning wildly.

This blow was like stabbing a hornet's nest, the sound of explosions began to come from the inside of the Dan furnace, and the terrible fire began to rage inside the Dan furnace, Lou Yi was engrossed in wandering around the Dan furnace, and his palm continued to beat rhythmically on the outside of the Dan furnace, and his true yuan was driven into the inside of the Dan furnace through the outer wall.

However, it may be because of the high level of the Raiding Grass, which caused his efforts to be half the effort, which made beads of sweat quickly appear on his forehead again, but he couldn't give up halfway now, otherwise this extremely precious Raiding Grass would be scrapped.

In this way, Lou Yi and this fairy grass began a tug-of-war over time, but the contest between them, it was the Nine Dragons Zhuzhu itself that suffered, after all, there were also a lot of nether things integrated into the Dan furnace, with Lou Yi's cultivation now, such a high-intensity beating, the consequences can be imagined.

The Dan furnace began to make a piercing sound, as if to remind Lou Yi that it was about to be unable to hold on, but Lou Yi couldn't do it halfway, and in desperation, he could only use his spiritual power to fill the vulnerability of the Dan furnace, so that his spiritual power consumption was greater.

After a long period of refining, the robbery grass finally began to slowly decompose, but the power of the thunder and fire generated suddenly increased by more than ten times, and cracks had begun to appear inside the Dan furnace, and Lou Yi could only continue to fill it with spiritual power.

This stalemate passed for another three days and three nights, during which Lou Yi's spiritual power began to gradually dry up, and he began to swallow the rejuvenating Molten Fish Pill, which was accidentally refined when he was refining the stomach-hungry pill for Yan Qing, but this thing was only a half-finished product at the beginning, and the effect was really not very good.

But with the improvement of his cultivation, coupled with the fact that he obtained a large number of herbs in the upper realm, when he returned to the secret realm after the tribulation, he took the time to refine another batch, these are the products of the improvement, and the effect is not bad.

At this time, they were poured into the mouth of the whole bottle, in addition to this, Lou Yi also used the soul power stored in the life and death order, so that it could withstand this terrifying spiritual consumption, and after another three days and three nights, the robbery grass finally succumbed, and the Dan furnace gradually quieted down, and Lou Yi was relieved.

But to refine the three tribulation pills next, but it still needs continuous time, Lou Yi while consolidating the Dan furnace with spiritual power, while starting to make preparations for the next step, he will ephedra vine, fire spirit branches, and the powder and juice formed after smelting, according to the weight of three to one to one, slowly injected into the Dan furnace, and then immediately increased vigilance and concentrated on consolidating the Dan furnace.

Suddenly, there was a loud bang, and the juice of the robbery grass that had been divided into three herbs once again made waves after coming into contact with the ingredients of these three herbs, and three-colored clouds appeared in the sky above the Dan furnace, and they continued to impact the top of the Dan furnace, trying to get out of it, and it was accompanied by a dense thunder during the process.

The top cover of the Dan furnace holding the pearls of the Nine Dragons emitted a strange firelight, it seemed to come to life, and pressed the top cover of the Dan furnace with its own body, preventing the three-color fire cloud from flying out of the Dan furnace, and at the same time, the other eight dragons also came to life, and for a time the nine-colored fire in the hall flew together, and accompanied by the sound of the dragon's groan.

The prison ox and the mocking wind broke away from the ears of the furnace, they rotated at high speed around the Dan furnace from end to end, and the two different fires formed a ring of fire and began to defend the Dan furnace, as a support for the entire Dan furnace, it also raised its head, and raised its back upwards to support the Dan furnace high.

Originally, these nine dragons were the guardian beasts that Huo Yan used nine kinds of strange gems to refine through the strange fire in the Ten Thousand Fire Catalogue, the purpose was that once Lou Yi could not be distracted by refining the pill, they could play a protective role, but now Lou Yi did not encounter danger, it was the Dan furnace itself that encountered danger.

Now there are cracks everywhere on the Dan furnace, if it weren't for Lou Yi using his spiritual power to constantly fill these cracks, I'm afraid the Dan furnace would have cracked a long time ago, but even so, their appearance also indicates that the Nine Dragons Hold the Pearls may not be able to be saved.

Lou Yi didn't expect things to turn out like this, he still overestimated the quality of the Nine Dragons Holding Beads, it was probably the most powerful Dan Furnace when it was in the Kunwu Realm, but this is the Upper Realm after all, what he refined is the Upper Realm Pill after all, it was not bad at first because it could still be maintained, but the quality of the Three Tribulation Pills was even more difficult than the semi-finished Ziming Golden Pill he had refined before, and Lou Yi didn't realize this, which caused the current situation.

However, there is no turning back, all he can do is to apologize to Huo Yan later, after all, this is the other party's painstaking work, Lou Yi sighed silently, adjusted his spirit and continued to use Shennong's hands, he had to get everything done as soon as possible.

With the continuous squeezing of the true yuan and the furnace fire, as well as the assistance of the nine dragons, the three-color fire cloud in the furnace gradually turned into a spiritual liquid rain and fell from above the Dan furnace, and at this moment, Lou Yi made a move, and the blood-red powder that melted the grapes and the karmic fire Lingzhi was poured into the Dan furnace.

The Dan Furnace, which had just calmed down slightly, shook violently again, and this time the frequency was stronger than the previous combined, and now all the materials had fallen into the Dan Furnace, and Lou Yi also began to exert his full strength at this moment.

He mobilized all the true elements of his body in one breath, and flew up to the Nine Dragons Holding Pearls Dan Furnace, at this moment the Nine Dragons performed their own duties, surrounding the Dan Furnace, forming a special ladder for Lou Yi to step on.

Lou Yi used all his spiritual power to defend the Dan furnace itself, and at the same time peeked at every detail of the changes, his figure began to become blurred, and his palm rhythmically slapped the Dan furnace, forming a special resonance with the roar inside, suppressing the internal sound to leak out.

His figure wandered up and down the nine metal dragons, his toes on them, so as to quickly rotate around the Nine Dragons Holding Beads, at this moment the Dan furnace was like a sealed metal sphere, full of cracks, at first glance it looked like a human vein, emitting a faint red light.

At this time, the internal pressure of the Dan furnace was gradually rising, and the power of the fire was burning everything inside, and the other materials did not want to sit still, so they began to walk in the wind, and they turned into mists of different colors, which at first glance looked like dragons overturning rivers and seas.

They floated up and down in the ocean formed by the three-color molten liquid, fighting each other and hitting each other, they originally wanted to escape from this place, but Lou Yi's Shennong scattered his hands, and with the aftershock formed by the true yuan, they were suppressed in the Dan furnace, and they who couldn't get out of the trap naturally became extremely irritable.

There was a violent roar from the entire Dan furnace, and Lou Yi was close to filling the new cracks in the Dan furnace with all his might, but the situation was still deteriorating, and the nine metal dragons let out a low roar, which sounded a little sad.

Lou Yi was very unbearable in his heart, but there was no way out at the moment, he only prayed that before the Dancheng, they could hold on, but the situation was far more complicated than he expected, I don't know if he saw that the quality of the Dan furnace was not good, and after they couldn't get out of trouble, they hit the idea on the Dan furnace.

They gave up fighting each other, and instead slammed into the inner wall of the Dan furnace with all their strength, the huge roar made Lou Yi's pressure rise sharply, and his spiritual power was being consumed at an alarming rate, and the pill was slowly no longer able to support his consumption rate.

At this moment, the nine metal dragons seemed to have made up their minds, they all looked at Lou Yi and gave him a final call, and then their bodies began to appear completely different flames, and under the incineration of the flames, they dissolved into nine different colors of molten metal.

Then the molten metal attached to the Dan furnace, and repaired its cracks, at this time, on the outer wall of the Nine Dragons Holding Pearls, a picture of the Nine Dragons appeared, and each dragon's eyes were inlaid with a strange gem, but now these gems have lost their spirituality and lost their original luster.

Lou Yi's pressure instantly decreased, but the situation continued, and the medicinal liquids who were unwilling to fail in arbitrage began to act more crazily, they began to pounce on each other frantically, and then desperately wanted to devour each other, in order to improve themselves, make themselves stronger, and then rush out of the shackles of this Dan furnace.

But Lou Yi naturally wouldn't let them get their wish, he exuded an amazing dragon aura all around him, and when his palm slapped on the wall of the Dan furnace, it made a huge roar, and the sound waves scattered these restless guys under the noise of Zhenyuan.

With the passage of time, and the killing between them, in the end, everything calmed down, and the medicinal liquid slowly began to solidify, Lou Yi did not relax because of this, in order to improve the quality of the elixir, he poured all the saliva of the six bottles of Xiao Mengbao collected before into the Dan furnace in one go.

After a few more days, the liquid medicine was completely solidified, but in the end, only two pills fell into the jade plate, and the others were all turned into ashes, but Lou Yi was already very relieved, because if there was one less pill, then his other plan would probably go bankrupt again.

Just when he took the pill out of the jade plate, suddenly a crisp sound came from the direction of the Dan furnace, and then the crisp sound kept ringing, Lou Yi looked up at the Nine Dragons Beads, and with the continuous sounds, the Nine Dragons Beads were completely cracked.

It split into hundreds of pieces of metal, Lou Yi collected them all, then carefully put them into the Qiankun bag, and said to them, "Thank you, thank you!"
