Pursuing Longevity With an Immortal Mansion

Chapter 749: Ashes of Alchemy Book

"Rumble"

The stone door slowly opened, and under the leadership of Wen Caiyi, a pretty female cultivator was brought to the room.

It had been a long time since she had seen the triangular-eyed cultivator come out, and this woman was already feeling uneasy.

It's just that now that things have come to this, under the nose of the high-level monks, she has no choice but to enter.

Seeing the blood on the ground, the female cultivator was secretly frightened, but she still walked to the futon and sat down tremblingly.

"Calm down your mind and relax your mind."

Liu Yu said lightly.

This time, I took a bright red pill, but as expected, it failed.

Looking at the corpse with a completely different death state, he showed no sadness or joy on his face. With repeated trials and errors, his thoughts gradually became clearer.

The second, third and fourth experiments failed.

"Your sacrifices are all worth it."

"The path to discovering truth requires necessary cruelty."

Liu Yu murmured, and then a wisp of green flame popped out, turning the body into ashes.

…

one year later.

Qingyang Peak, laboratory.

Liu Yu sat cross-legged on the futon, lowering his head and thinking about the "Soul Cleansing Pill". The 398th experiment was about to begin.

"Rumble"

The stone door opened, and a young man about sixteen or seventeen years old with a somewhat delicate appearance suddenly appeared in sight.

The maid Wen Caiyi bowed respectfully and stopped outside the door.

"Huh~"

The moment the stone door opened, the handsome young man felt a gust of cold wind coming towards him, and his body shivered subconsciously.

At a glance, one could tell that this boy was a novice in cultivating immortals.

There is a trace of childishness in his behavior, which is incomparable with old-fashioned people like Sanxiu Sanxiu.

However, high-level monks always have some similar characteristics, while the unhappy low-level monks who are depressed have different misfortunes.

The dangers of the experiment have been told. Now that we have arrived here, there is no way back.

"Hiss~!"

Despite the uncontrollable trembling and deep fear flashing in his eyes, the handsome young man took a deep breath, gritted his teeth and stepped into the room resolutely.

It moved slowly at first, then faster and faster.

"Greetings, senior."

Looking at the figure wearing a black robe with an unfathomable aura, the handsome young man quickly walked forward and saluted respectfully.

Regardless of whether it is useful or not, it is always right to have proper etiquette.

"No need to be polite, just sit down."

Liu Yu didn't mean to ask about the past, nor did he intend to ask about his name, Liu Yu said calmly.

After the first 397 experiments, the refining of the "Soul Cleansing Pill" has made breakthrough progress.

It was probably in the last few experiments that he discovered the real formula, so he was in a very good mood.

"Yes, senior!"

The handsome young man nodded respectfully, then sat down on the futon opposite him, and was instructed to meditate and relax his mind.

Although he behaved very immaturely before, this child entered the state of cultivation in just a few moments.

The basic skills in this area are very solid, and they perform better than many experienced monks.

Seeing this, Liu Yu didn't mean to talk nonsense. He used the magic formula with ease and pointed at the center of the pretty young man's eyebrows to stabilize the Niwan Palace.

After three breaths, the preparation is complete.

With a flash of inspiration from the storage ring, he took out a jade bottle and poured three pills from it.

Brown, green, black

After the first 397 experiments, there was a large amount of experimental data to support it. During the experiment, the recipe was continuously improved and every wrong direction was eliminated.

To this day, the correct refining method of "Soul Cleansing Pill" has been locked to a very small range by Liu Yu.

If nothing unexpected happens, among the three pills in hand, there should be a correct "soul-cleansing pill".

"Whether he lives or dies, it all depends on the fate of this junior."

With some expectation and without any pause, Liu Yu fired a burst of magic power and sent the dark elixir into the target's mouth.

"Concentrate your mind and use your energy to refine the elixir."

Pointing a finger at the center of his eyebrows, his consciousness was always paying attention to the situation of his physical body and Niwan Palace, and he said in a deep voice.

"yes."

The handsome young man nodded slightly.

The next moment, subtle spiritual energy fluctuations echoed in the room, and the boy began to use his skills to refine the elixir.

Under the observation of Liu Yu's spiritual consciousness, this boy had no privacy at all.

As the technique was running, wisps of gray air rose from the abdomen of the delicate young man, ignoring the obstruction of flesh and bones, and floated towards Niwan Palace.

After a breath, several wisps of gray air flow smoothly entered the Niwan Palace, and merged into its pale golden spirit.

"Uh-huh~!"

In an instant, the boy screamed involuntarily, and his face instantly turned black and blue.

The pain in the soul is many times greater than that in the physical body!

Subconsciously, the handsome boy instinctively stopped performing the exercises, wanting to end this extreme pain.

During his spiritual observation, Liu Yu clearly "saw" that as the gray air flow merged, the pale golden prototype of the target's fist-sized soul gradually became unstable.

The Yuanshen, which was originally only the size of a fist, has a tendency to gradually shrink.

During this process, a black impurity invisible to the naked eye is discharged, and the target soul becomes more condensed.

The essence is the concentrated one!

"He didn't explode and die immediately. It seems that this refining method is possible to refine the correct soul purifying pill."

Seeing this scene, Liu Yu was not surprised but happy.

The previous experimental goals all failed within three breaths, but the handsome young man insisted on not failing within five breaths, which is enough to explain certain problems.

Moreover, his soul was also tempered by the power of the medicine and became more condensed.

"Run the technique slowly and do not stop without my order."

With cold eyes, Liu Yu said in a deep voice.

If you want to reach the sky in one step and obtain resources unimaginable by thousands of monks, you will naturally have to pay an extraordinary price.

This is the price!

"Yes, Senior Qingyang."

The handsome young man did not dare to disobey Master Jin Dan's order, otherwise he would be dead and disastrous, and if he cooperated with the experiment, he might still have a glimmer of hope.

However, reducing the speed of the exercise and slowing down the effect of refining the medicine still alleviated a lot of pain.

Let this child not collapse because of the pain in his soul.

However, as the gray air flow continues to be tempered, its soul is gradually approaching the edge of collapse. This has nothing to do with the so-called "willpower".

In the Niwan Palace, the entire dark space was trembling, and small cracks appeared one after another, as if the sky was falling apart.

One breath, two breaths

After a few breaths passed, the cracks increased rapidly, and Niwan Palace was about to collapse.

Unlike the hundreds of previous experiments, which looked like a failure at first glance, the hope of success in this experiment was right in front of him, and Liu Yu would not sit idly by.

Immediately, he took out a variety of priceless spiritual objects and began to use them freely.

Under the control of magic power, it can be directly applied to the surface of the body of a handsome young man, or directly put into his mouth.

Thanks to decades of accumulation in the Central Territory, Liu Yu has collected many Yuanshen relics, more of which are effective for low-level monks, and many of them can stabilize Niwan Palace.

At this time, I saw the dawn of refining the "Soul Cleansing Pill" and used it without hesitation.

All kinds of spiritual objects that ordinary monks would never dare to think of were enjoyed by handsome young people who narrowly escaped death.

Blessings and misfortunes depend on each other, and great disasters are also accompanied by great opportunities!

Liu Yu personally assisted, and several Yuan Shen objects were well absorbed and quickly came into play.

In the extremely dark Niwan Palace, the mysterious "ancient" characters shine brightly, exuding the aura of eternity and immortality.

Wherever the glow reaches, it effectively prevents the spread of cracks.

Immediately afterwards, colorful air currents appeared one after another, quickly stabilizing the Niwan Palace that was on the verge of collapse, and closing the cracks at an extremely fast speed.

"good."

Noticing this scene, Liu Yu stopped taking action, with a slight smile on his face.

Combining theory with practice, his current Yuan Shen attainments placed in Tiannan will probably amaze many Nascent Soul old monsters.

Under the influence of various spiritual objects, not only did the Niwan Palace remain as stable as Mount Tai, but the tendency of the soul to collapse also disappeared, and the handsome boy continued to be tempered by the gray air flow.

The fist-sized pale gold soul grew stronger under the nourishment of various spiritual objects, and then shrunk under the tempering of the gray air flow, repeating this process.

Extreme pain continued to come from the soul, and painful and even distorted screams continued to be heard in the room.

Just by hearing his voice, you can imagine the pain that person is going through.

Fortunately, with Liu Yu's intervention, the handsome boy's life was not in danger.

One breath, two breaths, three breaths

Less than half an hour later, all the power of the black elixir was finally absorbed by the handsome young man.

At this time, the prototype of this child's soul was actually stronger than it was at the beginning, and it was even more condensed than some foundation-building monks.

Such an effect is naturally due to various Yuanshen creatures.

The total value of the spiritual objects used just now is almost equivalent to two "gold-forming pills". They were taken by a mere Qi Refining monk, and the effect was immediate.

"This kind of soul strength has surpassed many monks in the early and middle stages of foundation building."

"With only the third level of Qi Refining, the range of spiritual consciousness is about one mile, which is already comparable to that of newly promoted foundation builders."

"The most important thing is that after this cleansing, his spiritual potential has been greatly improved."

"Every time you improve your realm in the future, the growth rate of your soul should be higher than that of ordinary monks."

"good."

Under Liu Yu's observation, any changes in the experimental subjects were undetectable.

Overall, the experiment was considered a success, and he was quite satisfied with the results.

As for the few resources, he didn't care about it. As long as he could refine the "Soul Cleansing Pill", everything would be worth it.

After all, using the Immortal Mansion to induce the birth of spiritual creatures is much cheaper than normal.

"Hiss~"

"senior."

After a long time, the handsome young man opened his eyes, but couldn't help but gasp, and managed to gather his energy to speak.

At this time, he was sweating profusely, as if a basin of hot water had been poured over his head.

But if you can survive, you will get resources beyond your imagination.

In addition to the fear in this child's heart, uncontrollable joy arose, and the color of ecstasy was beyond words.

The voice of No. 398 sounded, surprising Liu Yu who was thinking.

"Don't worry, I'll keep my word."

"For a junior like you, I won't go as far as to break my promise."

Once he saw through the other person's thoughts, Liu Yu was in a good mood and said a few words.

"Thank you, Senior Qingyang!"

"Senior's great kindness and kindness will be unforgettable by the younger generation, and I will definitely do so in the future."

Hearing this, the handsome young man was overjoyed. Regardless of the pain of his soul and body, he struggled to get up and was about to salute.

Liu Yu gently raised his hand and fired a burst of magic power to stop this boy's movement.

"No need to thank me, it's just a transaction of equal value. You deserve all this."

Liu Yu regained her composure and said calmly with no expression on her face.

What the handsome young man didn't know was that there were 397 monks before him who had devoted their lives to the truth in obscurity.

The risk of trying the drug is so high that you will almost die.

Being able to survive by chance, to a certain extent, is indeed a chance for me. This is a fair deal.

Of course, Liu Yu was just a Qi Refining monk. It would be easy for Liu Yu to regret it, but it was not necessary.

Even though he was so close, with his current methods, it was too easy to control a Qi Refining monk.

In the process of refining the elixir, the handsome young man had no idea what spiritual objects he had taken.

Apart from using his skills to refine the medicine, this man knew nothing about the whole process, so there was no need to kill anyone and silence him.

Under normal circumstances, Liu Yu is still willing to keep his promise.

Next, he went into detail, asking the handsome young man how he felt during the process, and observing the subsequent changes after taking the elixir.

It was not until half a quarter of an hour later that Liu Yu called Wen Caiyi and arranged for a maid to stay with the handsome young man and arrange for him to practice at Qingyang Peak.

As for the three "Foundation Building Pills", they were handed over to this son on the spot.

This arrangement has deep meaning, not only to cash in the rewards, but also to observe the side effects of taking the elixir.

Some side effects may not occur immediately, but may occur after a period of time.

"tread"

The footsteps gradually faded away, and the handsome young man followed a maid, and the figure quickly disappeared from sight.

From beginning to end, Liu Yu did not ask for the name of the experimental subject, but recorded it directly by number.

As the realm improves, the essence of life changes, the influence of bloodline, tradition, etc. on the monks gradually weakens, and some concepts also change quietly.

"This experiment is barely a success."

"But just in case, the remaining two directions also need to be tested one by one."

In the laboratory, Liu Yu thought quietly.

This test is successful. As long as we continue in this direction, it will be possible to obtain the real "Soul Cleansing Pill" recipe.

However, the follow-up still requires a lot of experiments, which require the cooperation of foundation-building monks.

But it is not an easy thing to impress a foundation-building monk, and its influence is not comparable to that of a Qi-refining monk. If you are not careful, it may cause very bad effects.

To be on the safe side, Liu Yu will personally handle the entire process from beginning to end.

After pondering for a few breaths, he took out his alchemy notes and wrote down the entire process of the 398th experiment in his notes.

Then a message was sent to Wen Caiyi, asking the woman to bring someone in to continue the next experiment.

…

Improve your cultivation level and experiment with soul-purifying pills.

When you focus on two things, time flies very quickly and a year flies by.

One year later, the practice room.

Liu Yu looked at the longan-sized and light-gray elixir between his two fingers, and there was some fluctuation in his eyes.

After hundreds of experiments and the dedication of hundreds of Qi Refining monks and more than twenty Foundation-building monks, the real elixir recipe was finally deduced.

At this time, the number on the alchemy notes suddenly came to "437".

"Continue to observe for a while and make sure that the surviving monks have no serious side effects. Then you can almost take this pill."

After hundreds of experiments, Liu Yu is still very rigorous even though he is confident.

Make sure there are no serious side effects before taking the elixir yourself.

After putting away the "Soul Cleansing Pill" and recording the experimental data, he stood up and walked outside.

Soon after, Liu Yu came to a cliff alone, took out the thick "Book of Herbal Pills", and burned it with flames from his fingertips.

"Zizi~"

Under the illumination of red fire, the alchemy book will soon turn into ashes.

The biggest regret of Baicao Zhenxiu, who wrote the elixir book, was that he could not deduce the elixir recipe. He hoped that if someone who came after him could deduce the elixir recipe, he could burn a copy to inform him that he was dead.

The content of Baicao Alchemy Book is penetrating. Throughout his entire alchemy career, this book inspired Liu Yu the most.

Learning from previous knowledge was just a matter of effort, so of course he didn't mind completing it.

The soul-purifying elixir formula has been completely written on the last page of the elixir book.

"So, the fallen Baicao True Cultivator should have no regrets, right?!"

"This kind of monk who spends his life searching for the truth"

Liu Yu put his hands behind his back and silently watched the Baicao Alchemy Book turn into ashes, feeling a bit of respect in his heart.

In his opinion, Baicao Zhenxiu, who has spent his whole life studying the art of alchemy, may be greater than the Nine Dragon God Lord.

It has nothing to do with the realm of cultivation or honors and achievements.

"This Baicao Dan Book seems to have been given to me by my master when I was apprenticed to my master."

After a long time, Liu Yu's eyes flashed with an inexplicable luster.

Immediately, he blew gently, and the ashes of the alchemy books that fell everywhere were scattered to the mountains silently.
