Gu Fan looked at Cang Yan's four alchemy.

First of all, it can be seen that the four of them are very proficient in refining the first-grade Gathering Spirit Pill, and it is obvious that they have refined it more than once.

Secondly, their methods are basically the same. They all follow a fixed law, or a method.

And this method is completely different from the inheritance of the Immortal Doctor Sect.

Gu Fan became interested and observed carefully.

But soon he frowned.

Because he found that although this technique was also subtle, it had too many movements that were completely unnecessary.

It's too complicated!

If it can be streamlined, it can be compared to the techniques of the Immortal Medicine Sect!

The Secret Service's heritage in this regard is actually quite high.

It's just that the Secret Service obviously didn't understand this tactic.

And the consequence of not being thorough is that the number of Cheng Dan will be very small!

The facts also proved Gu Fan's guess, Cang Yan, **, Wu Hao, and Tan Minghui only had two Cheng Dan!

Although there is no difference in quality with the Gathering Spirit Pill refined by Gu Fan, it is only a difference in the number of Cheng Dan, which can already be compared to the difference between heaven and earth.

In this era of the end of the law, medicinal herbs are extremely scarce, even if the Secret Service doesn't know how to get so many medicinal herbs.

It certainly isn't endless.

With such a utilization rate of herbs, it can be said that Gu Fan is extremely distressed to see it!

"Teacher!" Gu Fan was a little stunned when he looked at the Gathering Spirit Pill that the four of them had successfully cultivated, and he mustered up the courage and shouted softly.

"Watch me refine it again!" Gu Fan came back to his senses, didn't say anything, and directly waved his hand and took out the Medicine King Dan Furnace, and put the Dan Furnace on the main seat of the Earth Fire.

When the four of Cang Yan saw the Medicine King Dan Furnace, their eyes suddenly lit up.

As an alchemist, although their level is not high.

But there is still a vision.

The Medicine King Dan Furnace is extremely extraordinary at a glance.

As an alchemist, who wouldn't want to have a good Dan furnace?

Gu Fan didn't care what mood they were in now, he wasn't here to show off the Medicine King Dan Furnace.

Gu Fan is to tell them what kind of utilization of medicinal herbs should be!

After Gu Fan started alchemy, Cang Yan's eyes didn't blink at all, and even the envy of the Medicine King Dan Furnace was completely put aside.

Gu Fan's alchemy technique was completely unfamiliar, which opened their eyes, and they always felt as if there were endless mysteries contained in it......

If you can take a closer look, it will definitely be very rewarding.

It's just that before they can see what the door is, Gu Fan has already been refined.

When they saw how many Gathering Spirit Pills Gu Fan had refined, they were completely shocked......

He rubbed his eyes in disbelief.

Eight! Eight of them!

This, this is too much, isn't it? There are only two Cheng Dan in theirs! This gap, this gap is a bit too big.

Speaking of which, whether it is Cang Yan or **, Wu Hao, and Tan Minghui, they actually have a little doubt about Gu Fan's true level in alchemy.

After all, Gu Fan is so young and his level is not high, how can he be so accomplished in alchemy.

But now, looking at the number of Cheng Dan that Gu Fan has refined the Gathering Spirit Pill, this suspicion has suddenly dissipated without a trace.

In fact, Gu Fan is also a little stunned now.

He had previously refined the Gathering Spirit Pill, and the Cheng Pill was only five.

According to Gu Fan's guessing and analysis, along with the improvement of all aspects of his level, coupled with the refining of the Medicine King Dan Furnace, he also used the earth fire to refine.

It will definitely increase in the number of Cheng Dan.

But even if Gu Fan had an estimate, it was only estimated to be seven.

It's two more than the original, which is already amazing!

But now, it is directly into eight pills!

Even Gu Fan felt that if he hadn't just wanted to demonstrate to the four of Cangyan this time, he would have been a little more attentive...... The limit of nine Cheng Dan, this is not impossible to reach.

It seems that his own strength and external conditions are indeed very, very helpful to alchemy.

"Ahem!"

"See, what did you waste on the herbs before!"

Gu Fan has not forgotten his own purpose.

"That ......" Cang Yan hesitated for a moment, and opened his mouth to explain something.

"Yes, the Dan furnace I use is better than yours, the earth fire is stronger than yours, and the technique seems to be better than yours!"

"But is that a reason?"

Gu Fan knows that these factors do have an impact on the number of Cheng Dan, but now they definitely can't say that!

If so, then what else is there to 'educate' them?

"I'll use your Dan furnace, your earth fire, and even your methods to refine it!"

In order to convince them, Gu Fan also fought hard.

It's like subduing them.

Only by letting them truly see the strength of Gu Fan in alchemy, can they become dead set on Gu Fan!

"Our methods?" Cang Yan couldn't believe it, could it be that Gu Fan also knew about the secret service's alchemy techniques before?

"I watched your alchemy earlier and learned some of your techniques, and I feel that there is still too much room for improvement in your techniques!"

"Actually, although the technique is important, it cannot conform to the form, and what technique is most suitable for you!"

"What is the most direct and effective method, this is the most important!"

Gu Fan was talking, and he had already signaled to use the ** Dan furnace to alchemize.

Then, under the gaze of the four of Cang Yan, Gu Fan really started alchemy with the techniques of the secret service.

It's just that soon Cang Yan and the four of them found that although the technique was still theirs, too many movements had been removed.

It seems that in Gu Fan's hands, this is a completely new and another alchemy technique.

Gu Fan controlled the earth fire while using this new method to alchemy.

This is actually a test for Gufan.

Fortunately, what was refined this time was only a first-grade and lower-grade Gathering Spirit Pill, if the quality of the pill was higher, Gu Fan would not dare to make such a big attempt.

Gu Fan was completely immersed in it, and experienced the contrast between this unfamiliar technique and his own alchemy technique, as well as some of Tianchenzi's alchemy techniques!

Inadvertently, Gufan has improved a lot......

When the Gathering Spirit Pill came out, Gu Fan didn't even check how many Cheng Dan there were for the first time.

Instead, he closed his eyes slightly, merging the many thoughts in his mind.

Gu Fan felt like he had absorbed some of the things in Tianchenzi's memory for the first time and turned them into something that belonged to him.

This feeling is full of harvest and makes Gufan have a joy from the deepest part of his heart.

However, Gu Fan closed his eyes to recuperate, but the four of Cangyan couldn't help but be curious in their hearts.

Because in addition to the fact that Gu Fan's technique at the beginning was very similar to their alchemy technique, in the later period, it seemed that it had completely become a different technique.

Even this technique does not belong to the same system as the previous technique used by Gu Fan.

Could it be that Gu Fan created his own alchemy technique in alchemy?

That's amazing, isn't it?

So, what about Cheng Dan!

No matter what the method is, the key is to look at Cheng Dan.

As for whether the refining was successful...... The four of Cang Yan didn't think about it at all, because it was simply impossible.

Nine!

When Cang Yan and the four of them saw the number of Cheng Dan in the Dan furnace, their eyes almost fell out.

With one furnace of medicinal herbs, the number of extreme pills that can be refined is nine!

This is the way of heaven!

No one can surpass that.

But nine, nine belong to legends! Even the limit is only a guess.

It seems that no one has ever become a pill nine!

This was true even before the end of the Dharma era.

This is true, Gu Fan can know from Tianchenzi's memory that in alchemy, the situation of nine pills in one furnace is really just a legend, and no one has reached it at all.

The four of them were speechless.

Previously, Gu Fan used such a good Dan furnace, used the main vein of earth fire, and coupled with his unique alchemy technique of the Immortal Medicine Sect, he became eight pills!

They were already shocked and didn't know what to say.

But now it's okay, there is no good Dan furnace, it's not the main vein of Earth Fire, and even the alchemy technique has a bit of a shadow of their secret service line......

Under such circumstances, Cheng Dan has reached the legendary limit of nine.

What else can be said? What else can be said at this time?

When Gu Fan woke up from his contemplation, he was looking at the four Cangyan who were stunned.

Then, he saw the nine pills lying quietly in the Dan furnace.

At this moment, Gu Fan was also shocked.

I was really blown away.

He didn't expect that this kind of practical combination of many alchemy techniques would be able to turn nine pills!

Extreme numbers!

In fact, Gu Fan didn't even think about it.

Alchemy is a purely technical activity...... Since it is a technical job, how can it be pushed to the limit?

But now......

However, Gu Fan soon adjusted his mentality and said with a smile: "Now you know how low your utilization rate of medicinal herbs is, right?"

"Teacher, we ......" ** face was full of admiration.

What suspicions, to hell with it!

It's the limit of nine, and you still doubt it, what else do you suspect?

"It's okay to know the gap, in fact, I can see that your foundation is very, very good!"

"I don't hide my secrets, today I will tell you some alchemy tricks!"

"I can also provide you with herbs to practice your hands!"

"But...... Within three days, if any of you have less than five Cheng Dan, I'm sorry, then leave here!"

Gu Fan's expression was stern.

Give each other some pressure and make the future easier, then let them grow!

As for the situation of teaching the apprentice and starving the master, Gu Fan will never allow it to happen.

Gu Fan also believes in his own charm, such a situation cannot happen to him.

Cang Yan's four expressions were stern.

Especially Cangyan.

**, Wu Hao, Tan Minghui are better. They are still young after all.

If Cang Yan was really kicked out by Gu Fan...... Do you still have this face?

"Regarding alchemy, I think ......" Gu Fan didn't care what the four of them thought, and immediately opened his mouth to speak.

This kind of narration is a new understanding of Gufan, a new system!

It is a new system that goes straight to the myth of the limit of the nine Cheng Dan! Mobile phone users please visit wènhttp://mnet
