Immortal Palace Longevity

"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.

But now that the matter has come to this, under the eyes of the high-level monks, she can only enter with all her strength.

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 up, 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 Purifying 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 acted 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 the "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 child 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 prototype of the target's fist-sized pale golden 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 die in front of him, 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 naturally 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 on 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 much 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. 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 suck in the cold air, and managed to gather his energy and 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 will be unforgettable by this junior. In the future, I will definitely..."

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 drug testing is so great that almost one in ten people will die.

To be able to survive by chance, to some extent, it is indeed the boy's chance, and this is a fair deal.

Of course, he is just a Qi-refining cultivator. It is easy for Liu Yu to regret, but there is no need.

Even though he is close at hand, it is too easy for him to manipulate a Qi-refining cultivator with his current means.

During the process of refining the elixir, the handsome boy had no idea what spiritual objects he had taken.

In addition to refining the power of the medicine, the boy knew nothing about the whole process, so there was no need to kill him.

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

Next, he asked the handsome boy about his feelings during the process and observed 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 a maid to take the handsome boy away and arrange him to practice at Qingyang Peak.

As for the three "foundation-building pills", they were handed over to the boy on the spot.

Such an arrangement has its own meaning. It is not only to redeem the reward, but also to observe the side effects of taking the pill.

Some side effects may not occur on the spot, but may only erupt after a period of time.

"Tap tap"

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

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

With the improvement of realm, the transformation of the essence of life, the influence of blood, tradition, etc. on the cultivator gradually weakened, and some concepts also changed quietly.

"This experiment is barely successful."

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

In the laboratory, Liu Yu thought quietly.

This experiment was successful. As long as we continue in this direction, we may get the real "Soul Cleansing Pill" recipe.

However, there will still be a lot of experiments in the future, which requires the cooperation of foundation-building cultivators.

But it is not a simple matter to impress foundation-building cultivators, and their influence is not comparable to that of Qi-refining cultivators. If you are not careful, it may cause very bad effects.

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

After a few breaths of contemplation, he took out the alchemy notes and wrote down the process of the 398th experiment in full.

Then he sent a message to Wen Caiyi, asking her to bring people in to continue the next experiment.

…

Improve cultivation, Soul Cleansing Pill experiment.

Focusing on two things, time passed extremely quickly, and a year passed in a flash.

One year later, in the training room.

Liu Yu looked at the longan-sized light gray pill between his two fingers, and his eyes fluctuated slightly.

After hundreds of experiments, hundreds of Qi Refining cultivators and more than twenty Foundation Building cultivators, the real pill formula was finally deduced.

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

"Continue to observe for a period of time, and when those cultivators who survived are determined to have no serious side effects, they can almost take this pill."

After hundreds of experiments, although he was full of confidence, Liu Yu was still very rigorous.

To make sure there are no serious side effects, he would take the pills himself.

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

Not long after, Liu Yu came to a cliff alone, took out the thick "Hundred Herbs Pill Book", and burned it with flames from his fingertips.

"Zizi~"

Under the red flames, the pill book will soon turn into ashes.

The biggest regret of the Hundred Herbs True Cultivator who wrote the pill book is that he failed to deduce the pill formula. He hopes that if the later generations deduce the pill formula, they can burn a copy to inform him who has died.

The content of the Hundred Herbs Pill Book is incisive and profound. Looking back on his entire alchemy career, this book has inspired Liu Yu the most.

Learning the knowledge of the predecessors is just a piece of cake, so he certainly doesn't mind completing it.

The recipe for the Soul Cleansing Pill has been fully written on the last page of the pill book.

"In this case, the fallen Herb True Cultivator should have no regrets, right?!"

"This kind of cultivator who spent his life exploring the truth..."

Liu Yu put his hands behind his back and silently watched the Herb Alchemy Book turn into ashes, with a little respect in his heart.

In his opinion, the Herb True Cultivator who spent his life studying the way of alchemy might be greater than the Nine Dragon God.

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

"This Herb Alchemy Book seems to have been given by the Master when I became his disciple."

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

He blew gently, and the ashes of the alchemy book that fell everywhere were silently scattered to the mountains.
