Nine days passed in a flash.

On this day, Gu Yao Lao Dao suddenly arrived ahead of schedule and appeared in the Alchemy Hall.

Wu Yan was in the corner of the Alchemy Hall, using the treasure that Gu Yao Lao Dao had used to refine him before, and was concentrating on refining the Detoxification Pill.

When Gu Yao Lao Dao arrived, although Wu Yan was aware of it, he did not make any response, and was still immersed in alchemy.

On the ground in front of him, there were dozens of jade bottles of different sizes containing pills at this moment, and each jade bottle obviously contained a different detoxification pill.

Seeing that Wu Yan was concentrating on refining the Detoxification Pill, Gu Yao Lao Dao did not disturb him, but picked up the jade bottles on the ground and examined them carefully.

The first jade bottle he picked up was the outermost one that Wu Yan placed at random, and at first glance it was the work of the first alchemy.

Uncork the jade bottle and poured out a detoxification pill, Gu Yao Lao Dao looked at it carefully.

"The best blood purification pill, the first alchemy, choose this pill as a practice, well, good, good. Although he failed to refine the number of pills in terms of quality, he was able to reach the best in the first refining, and his talent was quite good. ”

It's just that when Gu Yao's gaze turned to the jade bottle, he was slightly stunned, and couldn't help but glance at Wu Yan in surprise.

Because, there are actually eight Blood Purifying Pills in the bottle, two of which are of the best grade, and the remaining six grains all have the number of revolutions, and the one with the highest quality has even reached four revolutions!

If Wu Yan really refined this elixir for the first time, then this talent would be too demonic!

Gu Yao Lao Dao's gaze at Wu Yan couldn't help but be filled with an indescribable and complicated color.

Even he, when he first tried to refine the Saint Pill, he couldn't do Wu Yan's step.

This is not the detoxification pill refined by Wu Yan, how good the grade is, in fact, Wu Yan's first furnace of detoxification holy pill is actually a refining failure.

Only the elixir of more than six turns can be called the holy pill, and under the six turns, they are all the best elixir, even if there is no number of turns, as long as it becomes a pill, it also belongs to the best elixir.

But Wu Yan's bottle of nine Blood Purifying Pills, the highest grade is only four turns.

What really surprised Gu Yao Lao Dao was actually Wu Yan's Cheng Dan rate. He never expected that Wu Yan's success rate would reach 100%!

It's nothing short of a miracle!

Any alchemist, even Danzun, could not guarantee that his success rate would reach 100% when refining a certain pill for the first time.

The vast majority of alchemists, for the first time in alchemy, can have a three-percent success rate, which is already quite good.

The last time Gu Yao Lao Dao refined the pill, that is, the time when Wu Yan saw him refining the pill with mortal fire, although he only opened the pill furnace once, he directly refined thirty copies of the holy pill.

Among the 30 children's holy pills, only two of them have reached 100 percent, and most of the remaining 28 children have only 60 percent of the success rate, and even one has only 30 percent of the success rate.

Gu Yao Lao Dao glanced at Wu Yan deeply, and the complexity in his eyes was replaced by appreciation and admiration.

He then picked up the other jade bottles and examined them carefully one by one.

Seeing this, Gu Yao Lao Dao was once again stunned by Wu Yan's alchemy technique.

Because, he checked it in the order in which Wu Yan placed the jade bottle, but it didn't matter what he saw, which directly made him completely speechless.

The next dozen or so jade bottles, without exception, the detoxification pills in each jade bottle, no more, no less, are all nine!

And what's even more weird is that he checked more than a dozen jade bottles one after another, and found that none of them were the same.

And what made him even more speechless was that in each jade bottle, there was no holy pill above the sixth turn, and all of them were the best elixirs below the sixth turn.

Among the best jade bottles, there were nine top-grade elixirs, all of which had reached the fifth turn, but none of them had reached the sixth turn!

That bottle was also the detoxification pill that Wu Yan had just refined.

Gu Yao Lao Dao then grabbed and checked all the more than 20 jade bottles that he hadn't checked, and finally believed that Wu Yan had actually refined all the thirty-three antidote pills recorded in the "Divine Pesticide Codex" poison path this time!

What's even more amazing is that he only refined each detoxification pill once, but he succeeded in all of them, and the quality was not bad.

In fact, these detoxification pills, if they were sold outside the Desolate Ancient Demon Mound, they would definitely be sold out quickly.

Even if it is the worst detoxification elixir, as long as it is symptomatic, it is enough to lift the corresponding drug ban. No one knows this better than Gu Yao.

Of course, the higher the grade of the detoxification pill, the better the detoxification effect.

If it reaches the level of the Holy Pill, it even has the effect of breaking the ban, which is why he asked Wu Yan to refine the Six-Turn Detoxification Pill.

What's more, if you really want to surpass the Red Fire Heavenly Venerable in alchemy, just refining the Six-Turn Detoxification Saint Pill is not enough at all.

With Gu Yao's old way's plan, it was originally planned that as long as Wu Yan could refine the six-turn detoxification holy pill, he would immediately teach Wu Yan a special alchemy forbidden method.

This forbidden method can make the alchemist's alchemy improve by leaps and bounds in a period of time, and with divine help, no matter what kind of holy pill he refines, he can increase two to three revolutions out of thin air!

In other words, if Wu Yan could refine the sixth-turn holy pill, then with the help of this forbidden law, he would definitely be able to refine the eight-turned-nine-turn pill.

In this way, there is a certainty of defeating the Red Fire Heavenly Venerable.

It's just that now it seems that Wu Yan's talent in alchemy is obviously much more terrifying than he imagined, and if this situation continues, I'm afraid that without his help, Wu Yan may also surpass Chihuo Tianzun in the refining of the detoxification pill!

According to Gu Yao's old Dao, Chihuo Tianzun was not good at refining detoxification pills, what he was best at was refining all kinds of tribulation pills used to help Venerable overcome tribulations, as well as longevity pills that helped improve longevity.

However, with the arrogance of Chihuo Tianzun, he thought that no matter what kind of elixir Gu Yao Lao Dao instructed Wu Yan to refine, it would be wishful thinking to surpass him, a Dan Dao Tianzun who had been famous for tens of thousands of years, in just ten days.

After Gu Yao Lao Dao finished checking the detoxification pill refined by Wu Yan, a satisfied smile appeared on his face.

Although Wu Yan had not yet refined a six-turn Saint Pill, Gu Yao Lao Dao was not worried at all.

He looked at Wu Yan who was refining the pill with some curiosity. The detoxification pill that Wu Yan was refining at the moment was the first blood purification pill.

Obviously, this should belong to the second furnace of blood purification pills he refined, but whether it is the refining technique, or the control of flames, or the control of the way to purify blood poison, they are all extremely skillful, and they can't see the slightest stagnation.

This furnace of Blood Purifying Pill has not yet been refined, and Gu Yao Lao Dao has even been able to judge that he is afraid that the success rate is 100 percent, and there are at least three Blood Purifying Pills, which can reach more than six turns and become a Blood Purifying Pill.

It's just that when Gu Yao's eyes looked at the fire mansion of the Dan furnace, his eyes widened in shock, and he almost didn't jump up and jump to scold!

He stretched out his hand and pointed at Wu Yan, and opened his mouth several times to scold Wu Yan, but when he saw that Wu Yan was alchemy without distractions, as if he didn't exist, he couldn't help but didn't call out, as if he was afraid that this call would destroy a furnace of pills!

However, Gu Yao Lao Dao can no longer be as calm as before at this moment!

With Gu Yao's old way cultivating like this, why was he almost scolded by Wu Yanqi and couldn't help but scold?

There is no other reason, the Mortal Fire Origin in his treasure tripod, in less than ten days, was actually tossed by Wu Yan and there were less than thirty percent left!

This is simply a loser to the extreme!

It took hundreds of thousands of years for Gu Yao Lao Dao to collect the origin of the mortal fire of this furnace. During the period of refining a lot of pills, he was not willing to use this mortal fire, but chose to use his own natal fire.

But he really couldn't imagine that he had only been out for nine days, and his lifeline had been wasted so much by Wu Yan!

An even bigger question then surfaced in Gu Yao's old man's heart.

This is a mortal fire, not a yin fire, not a yang fire, not a variety of different fires in the heavens and all worlds, but a special holy fire that only existed in the ancient Hongmeng era, how could Wu Yan, an ordinary junior in later generations, know how to control this fire alchemy?

Gu Yao Lao Dao had traveled to the heavens and all worlds, and he had never seen other alchemists use this mortal fire alchemy, of course, it was precisely for this reason that he was able to collect so many mortal fire origins.

However, Wu Yan is at a critical stage at the moment, and it is impossible to stop.

Gu Yao Lao Dao remembered that he was like a cat scratching, but he could only be patient and wait for Wu Yan to finish refining the Blood Purification Pill.

Seeing that Wu Yan was actually able to skillfully manipulate the Mortal Fire Alchemy, Gu Yao Lao Dao was even more itchy, and he really wanted to have a good chat with Wu Yan and ask him where he learned to control the Mortal Fire.

Fortunately, although this furnace of elixir was relatively difficult to refine, Wu Yan still finished refining it quickly!

Skillfully extinguishing the fire, opening the furnace, and collecting the pills, Wu Yan successfully finished refining all the furnaces of blood purifying pills, and used a jade bottle that had been prepared long ago to collect all nine blood purifying pills.

Gu Yao Lao Dao was already impatient to wait, and when he saw that Wu Yan had put away the pill, he hurriedly put away the treasure tripod, as if he was afraid that Wu Yan would continue to use this tripod to refine the pill.

Then, without waiting for Wu Yan to speak, Gu Yao Lao Dao grabbed Wu Yan's collar, picked him up and grabbed him in front of him, and questioned Wu Yan: "Wu Yan, although you are the most talented alchemist that Poor Dao has ever seen, Poor Dao can't forgive you because of this! You are too much, do you know what you have done? You have ruined as much as seventy percent of the Poor Dao's mortal fire origin!"

Wu Yan shrugged his shoulders with a wry smile and said, "Senior, what are you doing here? Didn't you say it before, everything here is up to me, can I use whatever I want? The junior just completely follows the will of the senior, where is it excessive?"

Gu Yao Lao Dao was completely speechless when Wu Yan said this. Indeed, he told Wu Yan this before, but if he knew in advance that Wu Yan not only recognized Mortal Fire, but also knew how to control Mortal Fire, he would not let Wu Yan use that Baoding Alchemy Pill to kill him!
