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 your mind and relax your mind."

Liu Yu said calmly.

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 exploring 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 can tell that this boy is a novice in cultivating immortals.

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

However, high-level monks always have some similar traits, while the unhappy low-level monks have different misfortunes.

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

"Hiss~!"

Although he was shaking uncontrollably and there was deep fear 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 to seniors."

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

No matter whether it is useful or not, it is always right to have proper etiquette.

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

Liu Yu had no intention of asking 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.

He probably discovered the real formula in the last few experiments, 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 boy 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 and pointed it at the center of the pretty young man's eyebrows to stabilize the Niwan Palace.

After three breaths, the preparations are completed.

With a flash of inspiration from the storage ring, he took out a jade bottle and poured three pills out of 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 Purifying 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 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 kung fu 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 young man 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 concentrated!

"I didn't die immediately because my body exploded. 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 illustrate certain problems.

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

"Run the exercise 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 orders, otherwise he would be dead and would die right before his eyes. 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 medicinal power 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 do whatever he wanted.

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

Thanks to decades of accumulation in the Central Territory, Liu Yu has collected many Yuanshen artifacts, 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 items 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."
