I have to say that this Dan Dao event has actually changed the rules of master and apprentice in the bitter sea world for several epochs.

The six hundred and fifty alchemists who were waiting to be selected and assessed by Wu Yan in front of him were the lowest in their own cultivation, and they were also in the realm of the Great Saint Emperor, but Wu Yan was now only in the late stage of the Saint King realm, but they all wanted to worship him as a teacher.

Although these people worship Wu Yan as a teacher and want to learn alchemy, once they truly apprentice, this master-apprentice status will become a mark of their life, and they will not change because of anything.

Although the Dao of the Master is not the Dao of Heaven, in the world of the Sea of Suffering, it has a power equivalent to the rules of the Dao of Heaven.

If you go against the way of the teacher, you will be attacked by the way of heaven. Throughout the ages, no matter the right way or the evil way, they have attached great importance to the inheritance of the teacher's way, unless they encounter something that is against the people's morality, and few people dare to betray the teacher.

"I can be sincere from you, but I still have to ask solemnly here, are you really willing to worship me, the Holy King Alchemist, as a teacher?"

Standing on the high platform, Wu Yan asked the six hundred and fifty alchemists in the audience with a solemn expression.

Everyone's expressions have changed a little, but the faces of the vast majority of people are firm, they have been completely impressed by the alchemy of the ancient heavenly master, even if he only has the realm of the Saint King, two realms lower than himself, he is willing to worship him as a teacher.

I have to say that these people's yearning for a higher Dan Dao has reached a level that surpasses everything.

Only a few people had a slight hesitation on their faces, but thinking that by worshipping under the Ancient Heaven Master, they could learn stronger alchemy, and they didn't have to betray the original master, where to find such a good thing?

At the next moment, all six hundred and fifty people nodded their heads and agreed.

"We all sincerely want to worship under the Ancient Heavenly Master and learn alchemy!"

"In that case, then I would like to invite you to enter this Dan furnace and be tested. ”

Seeing the six hundred and fifty alchemists like this, Wu Yan was also secretly happy in his heart. To be honest, the more people learn to refine the merit pill, the more it will help him.

Wu Yan could have a hunch that before he grew up, the future world of the Sea of Bitterness would be temporarily divided between the Holy Spirit of Merit and the Dark Dao Venerable.

They are now staying in the False Realm at the same time, and they have not conquered the major holy cities and main stars in the True Realm, so they must be plotting something in the False Realm.

This thing should be the key to dominating the world of bitter sea in the future. Unfortunately, he had too little information to know what they were up to.

Even Gu Yao Lao Dao doesn't seem to know. In this case, Wu Yan had to make two preparations, one was to teach the refining method of this merit elixir in the Meritorious Heavenly Dao World, and the other was to make the Black Lotus kill clone and lurk into the Dark Heavenly Dao World, waiting for an opportunity.

These alchemists in front of him who are willing to worship him are the key to his future deployment.

Judging from the information collected by the Divine Machine Heavenly Pivot, these six hundred and fifty alchemists are basically from the vast majority of the Holy Cities and Main Stars of the Bitter Sea World, including the Holy Cities and Main Stars of the Ten Great Dan Dao Inheritances.

Even, Wu Yan also found a disciple of a certain Danzun on the stage, who was also mixed in the ranks of these six hundred and fifty alchemists.

Obviously, these people wanted to worship under Wu Yan's sect, and they were not only learning the method of refining the merit pill, but also coming to the Nine Dragons Alchemy.

For these alchemists with ulterior motives, Wu Yan was not worried. As soon as his Great Dao Saint Realm was revealed, a shining starlight Ding Furnace appeared in front of him, and then turned into a hundred-zhang giant furnace, suspended in the air.

This furnace is the Ding Furnace Seven Star Divine Furnace that Wu Yan obtained when he was in the Earth Spirit Realm. Of course, it is no longer appropriate to call it a seven-star divine furnace now, he has been re-transformed by Wu Yan and turned into a seven-star divine furnace.

This furnace was originally a Ding furnace specially refined by him in order to refine the space-time magic crystals obtained in the space-time magic river, and its original level was not high, and when it was just successfully refined before, it was not even an immortal weapon level.

Later, after two transformations, it finally only reached the level of Xuanqi. However, the real use of the Seven Star Furnace is not alchemy, but to purify all kinds of spars.

Its more special function is to absorb all kinds of false fire. The more Void Fire it absorbs, the stronger it becomes, and the more powerful it is to purify the hedron it has.

Just from the fact that in the Ancient Demon Tomb before, he used this furnace to collect the karmic fire of the twelve karmic fire red lotus, but there was no damage at all, and he could know its special features.

In fact, those karmic fires have now been absorbed by the Seven Star Furnace, and have become the strongest help for its purification of spars. However, the level of this furnace is still a mysterious weapon, and it has not been improved by absorbing karmic fire.

As soon as this furnace came out, everyone's eyes couldn't help but show a look of incomprehension. Whether it was the six hundred and fifty alchemists in the audience, or the other immortal powers in the Heavenly Machine Courtyard, this was the case.

Anyone can see that this Ding Furnace is just a Xuanqi Dan Furnace.

"May I ask Master Gu, this second round of assessment, is it to enter this Dan Furnace for alchemy, or to accept the test of the power of this Dan Furnace?"

Questions have been raised about this.

"My seven-star furnace has an extremely strong Void Fire Heavenly Power, which can refine all impurities. Although you have all mastered the trick of refining the merit elixir before, the merit elixir that has been refined still contains impurities to some extent and has not been refined. You can enter the Seven Star Furnace and use the void fire in it to refine the impurities in your respective merit elixir, or you can choose to reopen the furnace for alchemy. With the assistance of the Void Fire in it, it is believed that the probability of refining into a pill will be increased to a certain extent. ”

Wu Yan explained to the six hundred and fifty alchemists present with a calm expression. At this, he paused slightly, giving these people some time to digest.

After all, this kind of method, in the world of bitter sea, has never been used, and it is indeed a bit too shocking. Just by looking at what he said, even the faces of the twenty-five Danzun on the stage showed a look of shock, and you can imagine the great shock it caused.

"What? There is such a magical pill furnace in the world? It can actually help other alchemists refine the impurities in the pill and purify the purity of the pill?

"This is just a Xuanqi Dan furnace, even if it can refine impurities, it must only be able to refine the elixir at most, if I want to refine a furnace of merit holy pills, wouldn't it be useless?"

Hearing the chatter around him, Wu Yan smiled noncommittally and did not give any response or explanation.

"When you go in, you'll understand. Now, friends who are willing to accept the second round of tests can go in. ”

As he spoke, Wu Yan had already opened the roof of the Seven Star Furnace.

A strange void light portal appeared in front of everyone's eyes. Wu Yan stood next to the void light portal, looking at everyone with an indifferent smile.

In the Heavenly Machine Courtyard, the restrictions on the scanning of the Immortal Thoughts were extremely great, although everyone was full of curiosity about the Seven-Star Furnace, but they did not dare to use the Immortal Thoughts to scan, and they would not have thought that the Void Fire in the Seven-Star Furnace had become an extremely terrifying Void Heaven Fire because of the absorption of the power of karmic fire, which could refine any level of spar in the Bitter Sea World.

As soon as the Void Light Portal appeared, Fu Qingyang came out of the crowd, and was the first to step on the high platform, rushing into the Void Light Portal, and entering the inner world of the Seven Star Furnace.

People outside can't see the world inside the Seven Star Furnace. This test is only seen by Wu Yan alone.

The reason why Fu Qingyang chose to enter it without hesitation was not only to gain Wu Yan's approval, but also because he was more curious about this seven-star furnace. He really wanted to see what was so strange about this magical pill furnace that could purify the elixir.

It's not that he hasn't heard of Void Fire, but he doesn't know that it can still be used like this.

As soon as he entered the Seven Star Furnace, he found himself on a planet. Xian Nian glanced out and sensed that there were six other main stars in the regional space where this planet was located, and including the main star under his feet, there were a total of seven main stars in this area.

In addition to each of the seven main stars, there are four auxiliary stars, and above those four auxiliary stars, there is a strange power of fire emitted. As soon as his Immortal Thoughts came into contact with those auxiliary stars, he felt that there was an extremely terrifying Void Fire Heavenly Might, which could easily incinerate his Immortal Thoughts!

Fu Qingyang, who was aware of this, was suddenly shocked in his heart, and hurriedly withdrew his immortal thoughts.

"It seems that the flames above these auxiliary stars should be the void fire that Master Gu Tian said. It's just that I don't know what level this void fire is. In the classics left by the ancestors of this clan, there are also records of false fire. It's a pity that I didn't pay enough attention to it before, and I saw that the Void Fire couldn't be used for alchemy, so I didn't do much to understand it, and after I go back this time, I must have a good understanding of the Void Fire!"

While thinking about this, he took out his own Dan Furnace and the Meritorious Elixir that he had just refined, and then quietly waited for the arrival of the other testers.

Soon, one by one, figures continued to enter from a light gate in the void, and were teleported to seven different main stars by the power of this space.

After a few moments, in the end, all the alchemists who had passed the first round of tests chose to enter this seven-star furnace for the second round of tests.

After all, there are not many such opportunities, and if you miss them, you are afraid that there will be no more opportunities in the future.

Six hundred and fifty alchemists were scattered across the seven main stars. After almost all the alchemists came in, the first thing they did was to release their immortal thoughts to explore this strange space of the Seven Star Domain.

However, soon, all the alchemists, without exception, were like Fu Qingyang, and were shocked by the terrifying power of the Void Fire on the auxiliary star outside the main star.

It is common knowledge that the Void Fire can incinerate all the power of the Void. However, among all the people, the one with the lowest cultivation is also the Holy Emperor, and the highest has even reached the realm of Immortal Venerable, and the power of Immortal Nian will naturally not be bad.

But even so, he still couldn't resist the power of the void fire, and it was this discovery that made everyone couldn't help but be shocked by the special nature of the Ancient Heaven Master's seven-star furnace.
