Within the Seven Star Furnace, those people on the seven main stars, under the power of the Void Fire Heavenly Might, above their heads, were all shrouded in halos of different colors.

These halos are roughly divided into three colors.

The first is white, and the halo of this color means that the person's attitude towards the owner of the furnace is sincere and pure, and it is not mixed with other complicated moods.

The second is black, and the halo of this color is obviously an ulterior motive for the attitude of the owner of the furnace.

The third type is black and white, which means that the person's state at this time is complicated, and even they themselves can't figure out whether they sincerely want to worship Wu Yan's sect to practice alchemy, or if they have other thoughts.

For the emergence of this kind of situation, it was not unexpected by Wu Yan. In this Dandao event, there are only twelve disciples who are really recruited, and maybe another sixty more will be recruited as apprentices, but the rest will not be included in the command.

However, since he had recruited all these people into the Seven Star Furnace, he had his own ideas.

Since some people are not pure in their minds, they use false fire to refine them, so that those who manipulate them behind them will lift a stone and shoot themselves in the foot.

Under the urging of the mind, the karmic fire in the Seven Stars Furnace began to quietly shroud away invisibly to those people with complicated minds and ulterior motives.

Karmic fire is different from other flames, and if it is contaminated with karmic fire, it is contaminated with cause and effect. Since these people have impure thoughts towards Wu Yan, after being contaminated by karmic fire, they will fall into extreme pain and self-blame, until they suddenly wake up, belong to Wu Yan's disciples, and sincerely worship and obey, and then they will eliminate their negative karma.

Those who sincerely worship Wu Yan, even if they are contaminated with karmic fire, will not have any effect.

This is where the power of karmic fire comes in.

This method is a bit unfair, but for Wu Yan now, it is the best means to ensure that his safety is not threatened.

The power of karmic fire quickly melted into the halo of light that shrouded above the heads of those people, and lurked.

They themselves are unaware of this, and are still going on with the various things they are doing.

At the same time, in the entire Seven Star Furnace, all the merit elixirs that were taken out were refined under the refining of the Void Fire, and the impurities in them were indeed all refined, and the quality of the elixir was constantly improving at a speed visible to the naked eye.

Seeing this situation, all the alchemists showed a look of amazement and admiration on their faces!

"This Void Fire is really magical, it can really purify the pill! I heard that the Void Fire can purify the spars, but I don't know if it's true or not, so it's better to take this opportunity to try it!"

An alchemist, holding the merit elixir in one hand, had already taken out a high-grade holy source stone in the other.

It's just that before he could observe the changes in the top-grade Saint Source Stone, he saw that the top-grade Saint Source Stone suddenly flew out of his hand and landed on the main star below, and then submerged into the ground and disappeared.

The appearance of this scene was completely unexpected by him, and it was this alchemist who was stunned for a moment.

"What's going on?"

He scratched his head, and immediately looked around with a smile and laughter, but did not find anything unusual.

However, at this time, the merit elixir in his hand had already been purified, and his appearance had been upgraded from the original top-grade elixir to a level to the level of the best-grade elixir.

This change suddenly surprised and delighted him, and he quickly left behind the little episode that he had just taken out the top-grade Saint Source Stone.

He then took out his own Dan furnace and materials, and began to prepare to try to refine a furnace of merit saint pills here. After all, there are so many competitors, and if you want to stand out among so many people, it is obviously not possible to rely on the merit elixir alone.

What's more, Master Gu Tian also said that entering this seven-star furnace is also a test. However, the content of the test, Master Gu Tian did not say it explicitly, but just let everyone figure it out for themselves.

Thinking of this situation, this alchemist naturally didn't dare to slack off, and then he thought that maybe as long as he could refine a furnace of merit holy pills, he would be able to stand out from the crowd.

It's not just him who has this kind of thought, but the vast majority of people in the Seven Star Furnace have this kind of thought. At this time, there are not a few people who take out the Dan furnace and start refining the Saint Pill of Merit.

Just when these alchemists were working hard in the Seven-Star Furnace to refine the Meritorious Saint Pill, on the high platform outside, the Seven-Star Furnace had turned into a ruler-sized under the control of Wu Yanxin, and was held in his palm.

The surrounding Danzun, as well as the alchemists who were not selected in the audience, looked at each other one by one, secretly speculating about what was the mystery of Wu Yan's test.

Although the level of the Seven Star Furnace was far from being comparable to the Nine Dragons Sacred Tripod, its special features seemed to be no less than the Nine Dragons Sacred Tripod. Even in the realm of Tianzun, he couldn't spy on the mysteries.

Under such a circumstance, everyone could only wait outside, which made the atmosphere of the entire Dan Dao grand event a little dull.

Fortunately, the speed of time in the Seven Star Furnace is not the same as that in the outer world. When the alchemists who entered the Seven Star Furnace for alchemy had all completed their alchemy, only a few quarters of an hour had passed in the outer world.

The karmic fire had all dispersed into the bodies of those with ulterior motives, so Wu Yan opened the Seven Star Xuan Furnace and released all the alchemists inside.

"You can take out the merit elixir and holy pill that you have just refined, please evaluate it to all of you present, the twelve alchemists with the highest score can enter my door and learn more deeply about the refining of merit elixir. ”

After the six hundred and fifty alchemists came out, each of them held their own pills in their hands, and when they heard Master Gu Tian say this, they put the pills in their hands under the control of the Great Dao Saint Realm and presented them in front of all the Danzun.

In this evaluation, the inspection is naturally the level of the pill phase. Of course, there are only a few who can really successfully refine the Merit Saint Pill, and the vast majority of alchemists who refine the Merit Saint Pill for the first time have all failed without accident.

Under the verification of twenty-five Danzun, twelve of the most outstanding alchemists were selected.

As expected, the twelve alchemists were all disciples of the Holy City and the Main Star who had the Dan Dao lineage. In fact, these twelve alchemists are all disciples of some of the twenty-five Danzun here.

Wu Yan glanced at it and found that these twelve alchemists were all impure people. This situation did not surprise him.

Of course, to his surprise, Fu Qingyang, the descendant of the Fu family, was not selected. And Wu Yan had observed him before, and found that the merit saint pill he had refined had also reached the level of five turns, and it was no weaker than the twelve people who were selected.

"I don't accept it! The merit holy pills I have refined are no worse than them, why didn't they choose me?"

After the twelve people were selected, Fu Qingyang suddenly became anxious, and immediately stood up and said with an angry face.

Regarding his question, the twenty-five Danzun just smiled indifferently, and no one answered him, but looked at Wu Yan.

The Dan Dao grand meeting has evolved into a grand gathering of Gu Tian masters, and everything naturally depends on Gu Tian Master's intentions. It is true that they have other intentions, but at the same time, they don't want to offend the Heavenly Machine Tower, so they naturally want to give face to the Ancient Heavenly Master.

"Since it was jointly selected by the twenty-five Danzun, this result is naturally the most convincing result. However, presumably, among you, there should be an alchemist who is equally excellent and also wants to learn the method of refining the merit pill but has not been selected. I also have the intention of carrying forward this Dan Dao, so I will select another sixty alchemists as apprentices to follow me to practice the alchemy of the Merit Dan Dao, I don't know what you think?"

This is a bit arrogant, but when I think of learning from him, I can not only learn the Merit Dan Dao, but also have the opportunity to see the more advanced Nine Dragons Alchemy again, and the rest of the alchemists who were not selected, of course, did not hesitate to quickly nod and agree.

"Very good, I just counted, in addition to these twelve people, there are exactly sixty alchemists who have successfully refined the Meritorious Saint Pill, and that is them. I think everyone here should have no objection to this result, right?"

Fu Qingyang was originally very angry, but as soon as he heard this, he didn't say anything more. And the rest of the alchemists who failed to refine the Meritorious Saint Pill, although they were unwilling, they were helpless. After all, in this test, the final test is still the comprehension ability of Dan Dao and his own alchemy realm.

Fortunately, I came to participate in the Dan Dao Festival this time, and I have already obtained what I want, although I can't continue to follow Master Gu Tian to practice the more advanced Nine Dragons Alchemy, but it is also worth the trip.

After going back, if someone comes to the door to ask for the merit elixir or the holy pill, they will know how to refine it, so that they will not dare to take it over as before.

The seventy-two selected alchemists, under the witness of all the immortals in the Tianji Courtyard, stepped forward to bow to Wu Yan, and since then they have officially become disciples of the ancient heavenly master.

The one who presided over the apprenticeship ceremony was naturally the tower master of the Tianji Tower. With him in the background, everything naturally went very smoothly and smoothly, and no one came out to make trouble.

After the ceremony, the real goal of this Dandao event has actually been completed.

However, the Dandao event did not end. After all, this time, it was not easy to gather almost all the top alchemy masters in the Bitter Sea World, and it would be too much to say if it was not a good event to hold a Dan Dao exchange event.

The Lord of the Heavenly Machine Tower seemed to have been prepared, and after Wu Yan completed the apprenticeship ceremony, he took control of the Divine Machine Heavenly Pivot and changed the internal setting of the Heavenly Machine Courtyard again, turning it into a huge communication hall.

The Great Hall of Exchange is divided into twenty-eight areas, of which twenty-five Danzun each occupy one area, Master Gu Tian occupies one area, and two belong to the free exchange area.

The next time is the real Dan Dao exchange time. The alchemists either exchanged Dan Dao with each other in the free exchange area, or consulted with the twenty-five Danzun from the twenty-five regions, and started a warm exchange.

And the participants took this opportunity to communicate with the alchemists who they usually had no chance to meet, and asked them to help refine the pills.

The atmosphere of the entire Tianji Courtyard quickly became warm.
