Ling Yun just smiled indifferently and didn't say anything, in fact, there were definitely a lot of people who knew about his possession of the Yin Yang Holy Fire Lotus, but almost all of them were people from the six major forces, and they were also worried that after Ling Yun possessed the secret of the Yin Yang Holy Fire Lotus, it would attract more strong people to seize it, so they hid this secret.

This also has many benefits for Lingyun.

After preparing the Yin Yang Holy Fire Lotus, Red Flame Begonia, Holy Fire Grass and other elixirs for refining the Yin Yang Holy Fire Pill, Ling Yun had already begun to refine the spirit pill, and when all this began, the spirit deer suddenly became like a little fan girl, no longer asking, but looking at Ling Yun seriously.

She knew that if she disturbed at will during the alchemy process, it might have an impact on the elixir she had practiced, and it would also have an impact on whether she could refine the elixir, so she would become so well-behaved at this moment.

Generally speaking, an alchemist would not let others watch by his side, and since Ling Yun did not let Linglu leave, from the bottom of his heart, Xiao Linglu was still a little happy.

Outside the alchemy room, many teachers were waiting quietly, they had already guessed that Ling Yun was refining the four-grade spirit pill, but they didn't know what spirit pill to connect, so they were very curious.

And in the alchemy room, the dragon and snake both climbed out, and it looked at the Yin Yang Holy Fire Lotus carefully, the medicinal power on this thing had great benefits to it, so at this moment, the dragon and snake both wanted to climb up directly and eat this thing.

Ling Yun turned his head to Linglu and said, "Linglu, look at Shuangshuang, this thing is extremely attractive to it, so don't let it come!"

"Hmm!" Linglu hugged the dragon and snake, and at this time, Lingyun took out a few Qi Lings and scattered them to Linglu.

The spirit deer wanted to feed Shuangshuang, but after the dragon and snake Shuangshuang discovered the Yin Yang Holy Fire Lotus, they no longer had any interest in this Qi Lingsan, how could they eat it.

Ling Yun didn't care about these and continued to refine the elixir.

The process of alchemy has long been remembered clearly by him, and he only needs to deal with many details, in fact, it is not so easy for alchemists to refine the elixir, and he must control every opportunity, and he must be able to clearly feel that the elixir should be added at this time, and how much to add.

It takes some experience and talent.

Otherwise, wouldn't any martial artist who obtained the pill be able to refine the elixir?

Ling Yun was very careful and very attentive.

He saw every small change in the elixir in the alchemy furnace in his heart.

Then add other elixirs, neutralize, add some medicinal power, and so on.

As time passed, even Ling Yun had already begun to become haggard, refining this four-grade spirit pill, and indeed the consumption of his consciousness was extremely serious.

Moreover, Ling Yun was not originally a fire attribute martial artist, so it was also extremely hard to urge the kiln, but fortunately, Ling Yun had a lot of flame spirit runes in his hands that he had obtained from the disciples of Hongxi Pavilion.

These flame spirit runes were of different grades and methods, so every time Ling Yun urged the spirit runes, he was also cautious, which made his spiritual sense consumption even more serious.

But fortunately, this Yin Yang Holy Fire Pill is not a spirit pill that is difficult to refine.

Time was in a hurry, and after two hours, Ling Yun had already felt that in this alchemy furnace, even if he didn't need to control the flames, it was full of scorching power.

This is the Yin Yang Sacred Fire Pill.

Ling Yun was immediately overjoyed.

This Yin Yang Holy Fire Pill is a relatively peculiar elixir, it does not need the blessing of runes, and it cannot be stored, once it is successfully refined, it must be taken quickly.

When the Yin Yang Holy Fire Pill was formed, the dragon and snake both began to become more irritable, how much they wanted to rush over directly and swallow this thing.

Ling Yun knew how useful this Yin Yang Holy Fire Pill was for Shuangshuang, if he gave it this thing, I am afraid that the dragon and snake could directly break through to the peak realm of Yuan Dan.

However, Ling Yun would not be given it, because the Yin Yang Holy Fire Pill would be of greater use to himself. The most important thing was that Ling Yun didn't know if he had any other way than the Yin Yang Sacred Fire Pill now.

Therefore, when the Yin Yang Sacred Fire Pill was successfully refined, Ling Yun directly took it out and then took it.

A scorching power came, and this Yin Yang Sacred Fire Pill was like a fireball, causing terrifying damage to Ling Yun's throat and esophagus when swallowed.

Immediately after, this Yin Yang Holy Fire Pill dissolved in Ling Yun's body, and the endless flame power traveled all over the body along with the ten veins of the Qi Sutra, reaching the limbs and hundreds of remains.

For a moment, Ling Yun felt as if his body was already on fire.

The power of terror terrified him.

It was as if his body could turn to ashes at any moment.

It's painful!

Ling Yun was even about to roar, this kind of pain even exceeded the pain of the three-eyed blue flower fire poison at that time, the pain of fire poison was the pain from the outside to the inside, which could not be relieved, and the pain of this Yin Yang Holy Fire Pill was completely opposite, from the inside out, and it was a scorching pain, which made Ling Yun suddenly have the urge to cut open his chest and abdomen and take out that flame.

But Ling Yun knew that this was not a flame, and he also knew that even if he really cut his chest and abdomen, it would be useless.

Ling Yun hurriedly sat cross-legged.

Linglu was extremely panicked, wanting to help but not knowing what to do, and at the same time, she could feel that the temperature around her was rising rapidly, as if Ling Yun in front of her was a fire man.

In the process of Ling Yun's full efforts to refine the Fire Pill, Shuangshuang finally broke free of the Spirit Deer, and then jumped directly on top of Ling Yun's head, and began to absorb the power of the Fire Pill that was rapidly dissipating from his body.

Even the fire spiritual power that Ling Yun could not control and spread out was very strong, and it also had great benefits for both dragons and snakes.

After absorbing it for a while, although the dragon and snake had not reached the peak realm of Yuan Dan, they were already infinitely close.

And Ling Yun himself could feel that in the dantian, two Yuan Dan had already appeared, one was a white cold attribute inner pill, of course, this was just a fake pill, but I had to admit that the Yuan Dan that had inherited the power of the Ling family, even if it was a moment of fake pill, had already surpassed the Yuan Dan of many ordinary Yuan Dan martial artists.

And the other one is the Yin-Yang Fire Pill, the power of this Yin-Yang Fire Pill is extremely strong, and it directly suppressed the Ice Attribute Cold Pill, and in terms of size alone, the Yin-Yang Fire Pill will also exceed the Ice Attribute Cold Pill by more than five times.

This shows how powerful this fire pill is.

However, Ling Yun's body can't fully exert the power of this fire pill, and now he can only hope that after refining his clone, after transferring the fire pill, he can bring out the full power of the fire pill.

After Ling Yun refined this Yin Yang Holy Fire Pill, he turned his head to the spirit deer and said, "When I go out for a while, someone will definitely ask me about refining the spirit pill, you just need to say that I have not succeeded in refining!" As he spoke, Ling Yun left some of the dregs of the fourth-level spirit pill still in the alchemy furnace, and then urged a flame to heat it up.

In this way, even if the dean of Canghui Academy came, I am afraid that he would not be able to see any clues.

Although Linglu was a little puzzled as to why Ling Yun was like this, he still nodded and said, "Don't worry, teacher, I will definitely keep my mouth shut." ”

"That's good!" Once the news of Ling Yun's refining of the Yin-Yang Holy Fire Pill here spreads, I'm afraid that soon the people of the six major forces will find him.

Even if Linglu concealed Ling Yun's refining of the Yin Yang Holy Fire Pill, the people of Canghui Academy knew that they had refined a fourth-level spirit pill, and they would inevitably spread it everywhere, and it would also attract the attention of some people when the time came, once these people realized something, it would be a great danger to Ling Yun and the entire Canghui Academy.

Although Linglu wanted to make Ling Yun whole, she never found a chance, and as she got in touch with Ling Yun more deeply, she found that Ling Yun was really not simple, her strength was naturally undoubtedly strong, and she was decisive and capable, much stronger than their teacher Cang Cheng.

In addition, Ling Yun actually has such a deep understanding of formation, talisman seals and alchemy, if Ling Yun is still a master of refining, then he is really an all-rounder.

After glancing back, leaving no clues, Ling Yun said, "We can get out of here!" As he spoke, he was already shaking his head and sighing.

Linglu also looked sad.

Push open the door. At this moment, there are many people outside the door, most of them are learning alchemy, that is, Liu Hui's disciples, and there are more than a dozen teachers in front.

Ling Yun glanced at everyone and didn't speak.

"Ling Yun, I heard that you refined the Three-Rank Spirit Pill before?" a teacher asked directly.

At that time, there were many people here who had already seen it, so Ling Yun didn't hide anything, nodded, and said, "Yes, I can indeed refine the third-grade spirit pill, and it is indeed not difficult for me to refine the third-grade spirit pill, but it's a pity that these four-grade spirit pills... Hey!"

As he spoke, Ling Yun sighed.

"What, the refining failed?" the other teacher asked in surprise.

Linglu looked like a pity, and said: "The teacher has actually tried his best, almost a little bit to succeed, but... What a pity!" The little girl Linglu is really smart, and she even cooperated with Ling Yun to perform.

Ling Yun also smiled helplessly, and said, "If I were a little more careful, maybe this four-grade spirit pill would have been refined, but unfortunately... I'm still a freshman, forget it, let's go back and study it carefully, let's try it!" Ling Yun said as he handed over to everyone and prepared to leave.

"Teacher Lingyun, you have worked hard to refine the spirit pill, in that case, we won't disturb your rest and let the spirit deer send you back!" The vice dean nodded lightly.

This old guy didn't squeeze Ling Yun this time, Ling Yun suddenly understood, this person should know that Ling Yun could refine the three-grade spirit pill, for him, the three-grade spirit pill may be useless, but as long as he is an alchemist, it must have an effect, not to mention that Ling Yun has already begun to refine the four-grade spirit pill with common sense.
