Chu Nan and Dong Yuchen also looked over.

Chu Nan saw it at a glance......

The elixir in the other party's hand is white all over, and judging from the appearance alone, it no longer looks like a elixir, but like a bone.

This made many alchemists around him inhale one after another, and even more exclamations sounded.

"Bone Spirit Pill!"

"This ...... This kind of bone spirit pill, I have only seen it in some ancient books, Zhou Danshi here...... It is possible to refine a bone elixir of this shape!"

"Incredible!"

"Master Zhou Dan's alchemy attainments are so profound!"

Amid the exclamations of the surrounding crowd, an old man with gray hair slowly walked down from the second floor of the Mingdan Building.

His arrival made the people who were originally exclaimed here instantly quiet down.

Even that Zhou Danshi's face became solemn, and he didn't dare to show any arrogance on his face, and respectfully bowed to the old man.

"I've seen Su Lao. ”

Chu Nan also looked at the old man who appeared at this time.

The old man was dressed in a white robe, not an alchemist's robe, just an ordinary robe, and at the same time, the aura fluctuations emanating from his body were not strong, just the level of the first spirit realm, and the whole person looked ordinary and ordinary.

However, in the face of this old man, let alone Zhou Danshi, even the head of the alchemy department, in front of the old man, he was all respectful.

Because the old man in front of him ......

It's this famous Dan Tower, Connoisseur!

He is also the only connoisseur!

In the entire alchemy department, except for the minister Guo Haiya, no one knows the details of this Su Lao, they only know that the other party is the connoisseur of the Ming Dan Building, and only when their own elixir has passed its test and obtained its approval, can they be qualified to be ranked among the famous pills!

Those who are usually qualified to be connoisseurs, and who are also connoisseurs of the famous Danlou, must have unimaginable attainments in alchemy.

Even if this old Su has always been inconspicuous, no one dares to question it, and no one disagrees with his appraisal.

Su Lao walked straight in front of Zhou Danshi, his cloudy eyes, after looking Zhou Danshi up and down, he said with a smile.

"I remember you. ”

Just one sentence made Zhou Danshi feel flattered.

It is really the old Su in front of him, his status is extremely high, especially for a fourth-grade alchemist like Zhou Danshi, he has learned far more information than ordinary alchemists, and he knows the status of the other party here.

The look is more respectful at the moment.

"The villain can enter Su Lao's memory, it is the blessing of the villain, this time the villain came, he wanted to challenge the bone elixir in the building, and asked Su Lao to learn the pill for the villain. ”

As he spoke, Zhou Danshi raised his hands high and offered the bone spirit pill in his hand with great respect.

"Bone Elixir ......"

The moment Su Lao's seemingly cloudy eyes fell on the Bone Spirit Pill, the cloudiness in his eyes instantly dissipated most of them, revealing a trace of essence.

The moment he stretched out his hand to pick up this bone spirit pill, his whole person's momentum was even different.

Earlier, he was unremarkable, but now after picking up the Bone Spirit Pill, he is like a sharp sword out of the sheath, so that everyone around him can feel the fierce momentum.

"This Dan...... Not bad. ”

Su Lao stared at the bone spirit pill in his hand, nodded slightly, and made an evaluation.

"The highest level of the bone spirit pill is to reverse the pill as the bone, forming a thing that looks like a pill and is not a pill, like a bone and not a bone. Now that your Bone Spirit Pill has the shape of a bone, there are less than a hundred alchemists in the entire Jiang Kingdom who can do this. ”

Su Lao's evaluation is already a relatively high evaluation.

This made Zhou Danshi's face also exude excitement and expectation.

After carefully observing the Dan shape of this bone spirit pill, Su Lao flipped his hand, and a black Dan furnace only the size of a palm appeared in his hand.

This made everyone's eyes light up, and their hearts exclaimed.

"Jiandan Furnace!"

Zhou Danshi couldn't help but look forward to it.

It was not the first time he had seen Su Lao's Jiandan, and he clearly knew that the real Jiandan, when appraising the elixir, did not need to swallow the elixir in person.

If every Dan connoisseur has to swallow it in person when identifying the elixir, there are many disadvantages.

First of all, there are a lot of elixirs, there are a lot of uncertainties in themselves, and some elixirs are even invisible, and they are highly poisonous.

Secondly, the refining of some elixirs is already difficult, and there are even some elixirs, in the life of the alchemist, he may only be able to successfully refine once, if he just gives it to the connoisseur to swallow and identify, even if there is a result, the elixir is no longer there, and the gains outweigh the losses.

Therefore, for professional connoisseurs, they do not swallow the elixir to carry out the elixir, and usually use this kind of elixir furnace to identify the elixir.

And this kind of Jiandan furnace is completely different from the ordinary alchemy furnace.

In terms of value, the value of the Jiandan furnace is extremely amazing, and money cannot buy it, only by obtaining the identity of the Jiandan master and becoming a real Jiandan master, can you have the opportunity to obtain your own Jiandan furnace.

Jiandan furnace, you can see Dan, you can also alchemy!

And in terms of alchemy, it is far stronger than the ordinary alchemy furnace.

At the moment, after Su Lao took out the Jiandan furnace, he put Zhou Danshi's bone spirit pill into the furnace, and the moment he closed his eyes, there were bursts of black smoke in the Jiandan furnace, which diffused out, and these smoke drilled into Su Lao's mouth and nose, so that Su Lao could clearly feel the effect of this bone spirit pill.

He slowly opened his eyes, with a smile on his face, and nodded appreciatively towards Zhou Danshi.

"That's right, this bone elixir, not only has the shape of a bone, but its effect is far beyond this bone elixir on the counter, I announce...... This Dan will be my name Danlou Xindan!"

Su Lao's words came out.

Zhou Danshi was suddenly excited, and he bowed to Su Lao with an excited face.

"Xie Su Lao Jiandan!"

The alchemists around all of them also congratulated Zhou Danshi.

Zhou Danshi's mood was quite happy, and being able to leave three elixirs in the Ming Dan Building would not only greatly increase his status in the Alchemy Department, but also make him qualified to participate in the Alchemist Conference in three months.

This meeting is particularly important for the alchemists of Jiang Country, and those who can participate are all famous alchemists in Jiang Kingdom.

The minimum qualification for participating in the conference here in the Middle East Mansion is to leave at least three or more elixirs in the Mingdan Building!

Now...... He finally did.

Just when Zhou Danshi was happy here, and the alchemists around him congratulated him, a voice suddenly made all the noise disappear in an instant and became silent.

At this moment, everyone looked sideways and looked at a corner not far away, where two people were standing, and a fat young man at the head of them was standing there, facing Su Lao, and said something that shocked them.

"Old Su, I want to learn Dan too!"

Chu Nan's words made everyone look at them, and after they were shocked, many people frowned.

"Who is this fat man? I haven't seen it before. ”

"Looks like a new ......"

"New here?"

Everyone looked at Chu Nan's alchemist robe, and after seeing that he was just a first-class alchemist, contempt and disdain appeared in their eyes.

Someone immediately scoffed.

"The new fat man, do you understand the rules, this place is a famous Danlou, and it is also something that you can be wild as a first-class alchemist?"

"You also want to see Dan?"

"I don't know. ”

Chu Nan ignored the ridicule and ridicule of these people, looked towards Su Lao, bowed with his fists, and said very seriously.

"Su Lao, I want to challenge the name of this place, and I also ask Su Lao to learn Dan for me. ”

When Su Lao heard this, his brows couldn't help frowning slightly.

In the past, there had been a similar situation in the Ming Dan Building, where some first-class alchemists tried to ascend to the sky in one step, so they came to him to appreciate the Dan.

However, these first-grade alchemists can't even refine the most basic spirit pills well, let alone challenge the famous pills, such behavior is purely a waste of Su Lao's time.

So Su Lao formulated a rule.

But whoever comes to him for the Dan and if he fails, he must pay him a fee for the Dan to avoid those who try to ascend to the heavens in one step.

Since Su Lao formulated this rule, there has never been a first-class alchemist who dares to come to him to appreciate the pill easily.

I didn't expect such a person to appear again now.

"Do you know my rules?"

Su Lao looked at Chu Nan and asked coldly.

"Yes. ”

Chu Nan nodded.

"If I fail, I'm willing to pay Su Lao Jiandan. ”

Chu Nan's firmness and self-confidence here made Su Lao and the people around him stunned.

However, in most people's concepts, it is absolutely impossible for a first-grade alchemist to refine a famous pill, even if it is Su Lao, he has never seen it.

This made Su Lao's heart hesitate.

Zhou Danshi on the side also looked at Chu Nan at this time, and he asked.

"Which alchemist team are you?"

"Chen Ze. ”

Chu Nan said truthfully.

"Chen Ze ......"

When everyone heard this, their faces became strange.

At that time, many people were very optimistic about Chen Ze, thinking that he would definitely be able to become an important alchemist in the alchemy department in the future, but they didn't expect that under that huge blow, Chen Ze's whole person was devastated and reduced to a waste.

At the same time, most people are very clear about the current situation of Chen Ze's team, and in this case, as long as they are people with normal brains, they will not choose to join Chen Ze's team.

Chu Nan is still joining Chen Ze's team here, and with Chu Nan's words and actions now, this can't help but make them suspect that Chu Nan has a problem with his brain at all.

Zhou Danshi frowned, looked directly at the guards in the distance and said.

"This person is talking nonsense, he is not mentally normal, and he can't afford to pay for Su Lao Jiandan, so he will blast him out for me. ”

As a fourth-grade alchemist of the Alchemy Department, plus now that he has successfully left three elixirs in the Ming Dan Building, Zhou Danshi here, not to mention that he is powerful in the Alchemy Department, but he also has enough qualifications to order these guards.

"Yes, Zhou Danshi!"

A group of guards respectfully responded to the order, and their indifferent eyes locked on Chu Nan, and they were about to drive Chu Nan out.

Call!

Chu Nan flipped his hand, and many spirit stones appeared in his hand, and he looked directly at Su Lao and said.

"Old Su, I'm not fooling around, I definitely have enough money to pay for your Jiandan. ”

This made the footsteps of the guards who had just been raised fall again, and they all looked at Su Lao, waiting for Su Lao's instructions.

The biggest presence here......

After all, it's still Su Lao.

Even if it was Zhou Danshi's order, if Su Lao didn't agree here, they wouldn't follow it.

Su Lao frowned, and he didn't look at the spirit stone in Chu Nan's hand.

He made this rule, not because he coveted spirit stones, but because he wanted those who couldn't help themselves to retreat.

But now Chu Nan's insistence here made him feel a little different.

"Which one do you want to challenge?"

Su Lao asked.

Chu Nan raised his hand, pointed to a counter not far away, and said.

"Lingyu Pill!"

As soon as Chu Nan's words came out, everyone was stunned, and subconsciously looked at Zhou Danshi......

Zhou Danshi's gaze was instantly gloomy.

Now the Lingyu Pill of the Ming Dan Building is the Ming Dan he left behind!

Soon, though, the corners of his mouth curled up slightly, revealing a hint of sarcasm.

He felt that Chu Nan did this because he had just succeeded here, so he wanted to use his success to challenge his Mingdan, so as to gain benefits for himself, which is the so-called ...... Take advantage of the heat.

Even if Chu Nan fails in the end, he will become famous in the Alchemy Department because of this.

"A first-class alchemist, and he also wants to take advantage of Zhou's popularity?"

Zhou Danshi's eyes were full of sarcasm, he looked at Chu Nan, and said with a sneer.

"Since you want to challenge Zhou's famous pill, you must be full of confidence, so you might as well make a bet with Zhou, if you can successfully challenge and replace Zhou's Lingyu Pill, then Zhou will worship you as a teacher from now on, and in the future, you will be at your disposal and must not be disobeyed. Contrarily...... If you fail in the challenge, then you will give it to me, get out of the East Building, how about it?"

Many alchemists around him also echoed him.

"Yes, if you really have that ability, don't be cowardly!"

"If you don't dare to gamble, it means that you don't have that kind of confidence at all, and then you don't deserve to take on the challenge. ”

Zhou Danshi looked at Chu Nan with a sneer.

He believed that Chu Nan would not dare to gamble here, and his purpose was not to force Chu Nan to bet with him, he just wanted to use this to prove to Su Lao and all the alchemists here that Chu Nan's actions were just to take advantage of his popularity.

He believed that with Su Lao's wisdom, he would not fail to think of this.

As long as he proves that Chu Nan is taking advantage of the heat, then Su Lao has the right to directly drive Chu Nan out of here and refuse to be a Dan for him.

At the same time, it can also kill chickens and set an example for monkeys, so that other people who also have the desire to take advantage of the heat will die as soon as possible.

However, Chu Nan was completely surprised by Zhou Danshi's expectations, he looked at Zhou Danshi, there was no trace of fear on his face, and said lightly.

"Why don't you dare?"

As soon as these words came out, everyone around them was surprised.

Su Lao's eyes flickered slightly, and he was even more sure of the difference here in Chu Nan.

Zhou Danshi was surprised in his heart, but he didn't expect Chu Nan to really dare to bet.

Soon, though, he sneered, and the sarcasm in his eyes was even greater.

Although Chu Nan's actions were beyond his expectations, he never thought that Chu Nan, a first-grade alchemist, could refine enough Lingyu Pill to surpass him, even if Chu Nan gambled with him, it would only end in a fiasco.

"In that case, Liang Dan. ”

Su Lao looked at Chu Nan, and there was a trace of expectation in the depths of his gaze.

He could feel the difference between Chu Nan and knew that Chu Nan was definitely not the alchemists who wanted to ascend to the sky in one step in the past, nor did he want to take advantage of Zhou Danshi's popularity.

"I hope you don't disappoint me. ”

Su Lao thought silently in his heart.

Chu Nan flipped his hand.

Take out the Lingyu Pill that has been refined earlier.

Suddenly, everyone's eyes were all condensed on the elixir in Chu Nan's hand.

"It's ...... Lingyu Pill?"

When everyone saw that the elixir in Chu Nan's hand was a square-shaped elixir with a white body, they all questioned and ridiculed.

"Haha, what Zhou Danshi said is really right, this person has a problem with his brain at all, and he actually found a pill at random, and said that it was the Lingyu Pill. ”

Su Lao's brows also frowned slightly after seeing the elixir in Chu Nan's hand.

The elixir in Chu Nan's hand, whether it was the shape or color, was different from the Lingyu Pill.

On the surface, this is not a Lingyu Pill at all.

And after Zhou Danshi saw the elixir in Chu Nan's hand, the sarcasm in his eyes was even stronger, and at the same time, he was not too surprised by Chu Nan's move.

He wasn't worried at all that Chu Nan would be able to take out the Spirit Healing Pill that surpassed him, and felt that everything Chu Nan did was just to take advantage of his popularity here.

The ridicule and ridicule around did not make Chu Nan's face change in the slightest, he glanced at everyone indifferently and spoke.

"Since this is not my Lingyu Pill, then please tell me, what kind of Pill is my Lingling?"

As soon as Chu Nan's words came out, the many alchemists around him were suddenly speechless when asked.

Among the elixirs they are familiar with, there is indeed no elixir that looks like this.

"This pill is just a miscellaneous pill that does not enter the stream, and it is likely that it is not even a spirit pill, such a miscellaneous pill, why should we recognize it?"

Zhou Danshi smiled indifferently.

"Yes, of course I don't recognize such an unpopular Zadan. ”

Many alchemists sneered and agreed.

"Alright. ”

Su Lao opened his mouth, quieting everyone down, and he looked at the elixir in Chu Nan's hand.

"Whether this pill is a healing pill or not, after I identify it, I will know. ”

For some reason, Su Lao had a strong intuition, even if the elixir in Chu Nan's hand was not a Lingyu Pill, it was definitely not the kind of miscellaneous pill that did not enter the stream.

At that moment, Su Lao took this elixir from Chu Nan's hand, took it close to the front and back, and looked at it carefully.

"This Dan ......"

Su Lao stared at this elixir carefully, and his expression gradually became solemn.

When he first saw this elixir, it did look like an unpopular elixir, even with Su Lao's own well-informed, in his impression, he had never seen such a elixir.

But as he took a closer look, he was surprised to find that on top of this elixir, there was indeed some aura of the elixir, and the shape of the elixir was not simple.

This made his expression even more serious, even surpassing the seriousness when he observed Zhou Danshi's bone spirit pill before.

Su Lao's seriousness here did not make Zhou Danshi have any sense of crisis, and he still didn't think so.

The many alchemists around were surprised.

They originally thought that after Su Lao held Chu Nan's elixir, he would immediately judge this pill as an unpopular miscellaneous pill, but they didn't expect Su Lao to look at it for so long, and his expression was extremely serious.

It's been a long time......

Su Lao raised his head here, and his eyes shone brightly.

He looked at Chu Nan and said in a deep voice.

"This Dan...... I can't judge from the Dan form!"

As soon as Su Lao's words came out, he immediately caused a huge shock.

Since Su Lao became the master of Donglou Mansion, there has never been such a situation, usually when he is in Jiandan, from the appearance of the elixir, Su Lao can make an evaluation.

Although the effect of any elixir is the main thing, the quality of the elixir will also have a certain degree of influence on the effect of the elixir in a certain aspect.

This is Su Lao...... For the first time, I can't make a judgment on the Dan form of the elixir!

And the reason why he couldn't judge was because he couldn't tell whether this pill was the Lingyu Pill from the pill's shape!

In this case, he naturally couldn't make any evaluation through the pill form of this elixir.

Although Zhou Danshi still didn't believe that Chu Nan's spirit pill could surpass his spirit healing pill, Su Lao's inability to evaluate it here made him frown.

At present, Su Lao couldn't make a judgment from the Dan shape, so he could only put Chu Nan's elixir into the Jiandan furnace and began to identify it with the Jiandan furnace.

Like the bone spirit pill that had identified Zhou Danshi earlier, black smoke filled out of the Jiandan furnace and penetrated into Su Lao's mouth and nose.

Everyone looked at Su Lao, waiting for the result.

They clearly saw that when these black smoke penetrated into Su Lao's mouth and nose, Su Lao's body trembled violently.

Even though Su Lao still closed his eyes and didn't open them, his face showed an undisguised look of shock.

Such a look made all the alchemists around feel stunned, and it felt like a dream, which was extremely unreal.

Zhou Danshi sighed in his heart, and he had an ominous premonition, and his firm belief was shaken for the first time.

That's what a look......

They had never seen it here in Su Lao, even if it was Zhou Danshi's bone spirit pill earlier, although Su Lao appreciated it, he was not surprised.

Including the chief of the alchemy department, although there were six famous pills left in the famous pill building, Su Lao was not surprised when he identified these six famous pills.

And now......

An expression that no one had ever seen on Su Lao's face appeared in front of them, making their hearts feel dazed.

Later, the moment Su Lao opened his eyes, they clearly saw that everything in Su Lao's eyes had been completely replaced by shock.

Even if Su Lao didn't open his mouth here, at this moment, the expression on his face had already made the hearts of many alchemists and Zhou Danshi roar, and the feeling of uneasiness became more and more intense.

Su Lao looked at Chu Nan, and when those black smoke penetrated his mouth and nose, his mind suffered an unimaginable huge impact.

In his life, he has seen countless pills, whether it is those inferior elixirs or the most flawless elixirs, he has seen a lot, but he has never seen them...... Such an elixir.

"Subverting ......"

"This is a kind of elixir subversion!"

Su Lao's eyes shone brightly.

Before this, he couldn't imagine that this kind of elixir subversion would actually appear on a first-grade alchemist.

This made his gaze even hotter, as if it could burn everything.

"You...... What's your name?"
