However, this does not prevent Chu Li from watching these masters of alchemy with an attitude of appreciation and research, with the refining god tripod in his body, what kind of effect the pills refined by these people are, how they are refined, and what the grade is, Chu Li knows at a glance!

The elixir is the same as the magic weapon, there are all kinds of formations inside, but the formations depicted in the elixir are more subtle and obscure, and they are not easy to understand. Like the magic weapon, the grade of the elixir also depends on three aspects, the material, the true fire, and the formation!

Although this group of people are all experts in alchemy, there are still no particularly amazing characters, and the Dan Fire used by everyone is still only Xuanji Heavenly Fire, and not everyone can cultivate the Divine Fire without cultivating the Immortal Emperor!

Of course, it is impossible to refine the best elixir without a good elixir, the elixir is like a textbook, and it is as difficult as having no teacher to refine the elixir without a teacher!

These twenty-nine people still have nothing special, they all take out their own alchemy furnace very decently, and then put all kinds of alchemy materials into the Dan furnace, urging the Xuanji Heavenly Fire in the body to burn slowly, the only difference is the Dan recipe played by everyone!

All kinds of different Dan recipes hit the Dan furnace, flashing with a trace of ripples and various colors of light, and the materials in the Dan furnace also began a wonderful change, and various materials fused with each other!

Chu Li sat on the stands with great interest and admired these people's clever alchemy techniques, and he was secretly glad that he hadn't encountered any trouble until now. After all, Zhu Changle had said that his Earth Transformation Technique might still be discovered by others, but fortunately, there was no Immortal Emperor master in this refining event, otherwise Chu Li would really have to leave here with his tail between his legs.

Time is like a young girl who is being stared at by a handsome guy, as long as you look at her a few more times. She shyly trotted away.

In the blink of an eye, four years had passed, and the pills that most people had refined were almost out of the pill, and at this time, the old man who had been watched by everyone finally stood up from his meditation.

Everyone was wondering in their hearts, would he use the Heart Refining Method to refine the pill again this time? If so, with the help of the Divine Fire Land. There is no suspense about the champion of the alchemy competition!

Sure enough, the old man still didn't take out the alchemy furnace this time, but just took out dozens of alchemy materials from the storage ring, waved his hand and threw them into the air, his hands slowly waving in front of his chest, and all kinds of materials seemed to be controlled by an invisible force and began to slowly spin in mid-air!

And some connoisseurs couldn't help but be shocked when they saw the materials that the old man took out!

The middle-aged man in the green robe on the rostrum muttered: "Ice blue flower, 10,000-year-old green ginseng, fire tree fruit...... He...... He wants to refine the Tribulation Pill?"

As soon as these words came out, everyone present was shocked!

The Tribulation Pill, no matter which realm it is, is the best elixir. Although taking the Tribulation Pill does not allow you to survive the Heavenly Tribulation or the Divine Tribulation 100%, the effect of the Tribulation Pill is to restore your immortal power and mental consumption to the best state in an instant, just like the props in online games that instantly replenish human blood and demons!

Like the method of heart refining, although the refining method of the Tribulation Pill is not lost, the number of people in the entire immortal world who know the refining method will not exceed one pair of hands, and it has been a long time since I have heard of it!

All of a sudden, Zhu Changle, Wang Shengshou, and Bailian Immortal Jun all looked at the old man with a scorching look. Such a person who has reached the top level of refining and alchemy, this is a national treasure-level figure, even an Immortal Emperor master will put down his body to win him over!

It's a pity that there is a competition going on at this time, but the three of them already have a countermeasure in their hearts, and as soon as the refining event is over, they will immediately go to him to talk, and no matter how big the price is, they will draw him under their command!

At this time, the old man's entire mind was spent on alchemy, and the forbidden pill of the Crossing Tribulation Pill was not so easy to refine. Even he has never experimented before because of the difficulty of getting the material, only he has a wealth of theoretical knowledge, and as for whether the theory can be turned into practice, it depends on his current performance!

The black divine fire scorched the fused materials in the middle, and the old man's hands did not stop for a moment. A variety of different pill recipes hit the material. The sound of crackling kept sounding, like the beating of a drum in the heart of a man! Great drops of sweat swayed down the old man's head. It seems that the refining of this Tribulation Pill is much more difficult than refining the bronze mirror just now!

Almost every once in a while, the old man has to take a pill, otherwise he may not be able to continue!

Although most of the people present didn't know that the old man was refining the Tribulation Pill, but looking at his current struggle, everyone knew that the pill he refined was not trivial!

A year passed in the old man's non-stop taking pills, and he didn't know how many pills he had taken in a year, and he didn't know how many pills he had in his storage ring!

At this moment, he has become the focus of the audience, and everyone's eyes are on him, including other people participating in the ring, and everyone's eyes show a look of admiration!

Whether it is refining weapons or alchemy, sometimes it is a test of endurance and will, once you slack off, not only will you fail in refining, but you will also suffer backlash!

At this time, there seemed to be a little inexplicable change in the sky, but everyone's attention was attracted by the old man's alchemy, and no one noticed!

Seeing that the Tribulation Pill was almost the time of the final Cheng Dan, the old man's hands were so fast that he could only see the shadow clearly, and he suddenly shouted in his mouth: "Ning Dan!"

I saw that the blue-white object in the air, about the size of an egg, began to slowly compress under the blow of the old man's pill, becoming smaller and smaller, and finally turned into three small pills the size of a small thumb!

It was at this time that a purple lightning bolt struck down from the sky without warning!

At this time, everyone vaguely remembered that the Tribulation Pill was a thing against the sky, and every time it was refined, it would be accompanied by a Dan Tribulation, although this Dan Tribulation was not as exaggerated as the Divine Tribulation, but it was not something that ordinary Immortal Monarch level masters could resist!

Especially the old man in the ring, at this time, he has reached the point of running out of oil and lamps, under the power of Huanghuang Tianwei, can he hold on?

The purple thunderbolt came to the sky above the Tribulation Pill in the blink of an eye, and it was about to hit the Dan, if it was hit solidly, these three Tribulation Pills would also be scrapped!

At the moment when there was no room for it, a small cyan flag suddenly appeared in the old man's hand, and a strong blue light suddenly emanated from the small cyan flag, covering the three Tribulation Pills inside!

The purple thunderbolt instantly had a close contact with the cyan light mask, only to see the blue light on the cyan light mask kept rolling and shaking, and the entire light mask was also shaking constantly, as if it could be broken at any time!

The onlookers couldn't help but sweat for the old man at this time, and secretly prayed in their hearts that the old man could withstand the tribulation, after all, anyone who saw the three tribulation pills smashed in front of them would feel unbearable, it was something that could save lives!

However, they can't do it if they want to intervene now, once they intervene, the power of the Dan Tribulation will skyrocket in an instant, and when the time comes, not only will the pill not be saved, but they may also be seriously injured, so a group of people can only watch.

A purple thunderbolt slowly dissipated between heaven and earth, but this was only the beginning, far from the end! While the thunder and lightning had not yet arrived, the old man swallowed a pill again and took out small flags from the storage ring.

Chu Li's eyes lit up, it was actually a formation flag, but he didn't know how many levels of immortal arrays were depicted in these array flags!

More than a dozen palm-sized earthy yellow flags were placed on the periphery of the three Tribulation Pills by the old man, faintly forming a formation!

At this moment, two purple thunderbolts that were enough to be the thickness of an arm struck down again with the momentum of Thunder!

A dazzling yellow light suddenly emitted from a dozen small flags, enveloping the entire ring, and two lightning bolts struck it, like a small pebble thrown into a pond, only a small wave dissipated!

Only then did the onlookers slowly relax their hearts, and sighed in their hearts that the old man's array flag was strong in defense, and it was able to block the attacks of the two Dan Tribulation thunderbolts so easily, at least a fifth-level defensive immortal array!

That's right, the array flag that the old man took out was depicted in the fifth-level defensive immortal array, which was enough to resist the attack of the immortal emperor-level master!

In less than a minute, four thigh-thick purple thunderbolts descended again, and it seemed that they would double every time they landed, I don't know if the next time it was eight thunderbolts, if so, when would this be the end?

Four lightning bolts smashed the earthy yellow light mask, and after a stalemate with each other, the lightning dissipated again, and the light mask was still almost intact until now!

As soon as the thunder and lightning dissipated, the eight waist-thick purple thunderbolts instantly smashed down again, as if they didn't want to give people time to breathe!
