In the secret room, accompanied by the rhythm of rhythmic breathing and breathing, Yang Yu made his arms Tai Chi dribble over and over again, and the aura was compressed between the two palms to form a small glowing cyclone, illuminating Yang Yu's face in the secret room was red and blue.

A few arm-thick oil candles lit on the side, the candle flame was also as weak as a soybean with Yang Yu's breathing rhythm, and as big as a bull's horn for a while.

With a faint pop, Yang Yu slowly slowed down the speed of his movements with satisfaction, and as the last aura returned to the dantian along the tendons and veins and merged into the sea of qi, Yang Yu was so satisfied that he spit out the turbidity accumulated in his chest.

"Whew!"

Exhaling like a sword, a two-finger-wide white breath was exhaled and lingered in the air for a long time.

"Finally, the peak of qi refining has broken through."

He was only 18 years old and had already broken through the peak of qi refining, and this speed must not be slower than those geniuses of the Great Immortal Sect.

Thinking of this, Yang Yu's heart looked at the liquefied spiritual liquid that was placed in the corner of the secret room, and the vat was about to bottom.

The automatic atomizer on the side continued to atomize the spiritual liquid in the tank into mist and spray it into the air, and the whole room was foggy.

This tank is almost running out, and we have to use an air compressor to make a few more cylinders of spiritual liquid.

Getting up and taking off the robe that was stained with pores and squeezing out dirt on his body, Yang Yu took out a vat of spiritual liquid from the storage bag naked and poured it into the bath bucket.

Poof!

"Uh-huh~~~~~"

Shuang couldn't help but let out a moan in his mouth, and Yang Yu was so satisfied that he slowly soaked his whole body into the spiritual liquid along the wall of the barrel.

Even if this scene is seen by the Yuanying monk, he will scold the loser!

What kind of family? Bathing in an elixir?

Is there still a royal law? Is there still a heavenly principle?

！！！！！！！！！

With his arms around his knees, Yang Yu soaked himself in the spiritual liquid, slowly feeling the spiritual liquid absorbed along his pores, gradually washing every cell of himself.

In the pleasure of taking a bath in the spiritual liquid, Yang Yu slowly recalled the fact that he had made the spiritual liquid at the beginning.

Then, it was a few years ago, when I was still very thin.

....................

"Throw it, throw it away, throw it lightly behind the child, don't tell him!"

In a forest in the Yue Kingdom, a mysterious Xiuxian family set up a formation to cover a radius of more than ten miles, and it looked like an ordinary forest from the air, but when you enter it, you will find it.

In the middle of the two peaks, there are two twin lakes that are as bright as mirrors, and the bustling crowds surround the two lakes and fill them with antique buildings.

This is one of the four major immortal cultivation families in Spirit Beast Mountain, the clan land of the Yang family.

The closer you get to the two lakes, the stronger your aura becomes, and the farthest away from the two lakes are some mortals who can't cultivate.

All the children of the Yang family must be brought into the ancestral hall to test whether there is a spiritual root as soon as they are born.

If you have a spiritual root, when you grow up to 3 years old with your family, you will be taken away from your parents, and then you will be sent to the clan to study and practice together.

Therefore, Yang Yu has a vague impression of his parents in his life, and what he remembers most is the collective life of ethnology.

When the boys are 12 years old, if they have good qualifications and practice quickly, the family will recommend them to enter the sect to practice, otherwise, they will stay in the family and become family monks to serve the family.

Yang Yu was very lucky, he cast a good fetus with spiritual roots, and he won the family recommendation quota among the boys.

...............

During the rest time, unlike other children who laughed and played, Yang Yu would always find a place where no one was left alone and close his eyes and pretend to sleep, but in fact, he was immersed in the endless knowledge in the Tower of Ascending.

"Brother Yang Yu."

A soft and glutinous voice pulled Yang Yu back to the real world from self-absorption, looking at the little Lori holding a handful of wildflowers in her hand in front of her, Yang Yu couldn't help but touch her little head.

"It's Tuan Tuan, good."

"Brother Yu, why do you always sleep and don't you go to play with everyone?"

"I'm not going, just go play by yourself."

"Hey, Brother Xiaoyu's big lazy worm, slightly."

Looking at the little glutinous rice dumplings that made a grimace at himself in front of him, Yang Yu also played with his heart: "Okay, you dare to laugh at me, see that I don't." ”

"Hey, I can't catch it."

After a fight with Yang Nuomi, the group pet of the clan studies, Yang Yu finally paid a few snacks to coax her away.

After making a fuss, Yang Yu had no intention of continuing scientific research.

Sitting down against the big tree, Yang Yu stretched out his five fingers to block the sunlight, feeling the light through his fingers, Yang Yu couldn't help but think about the scientific research projects he had completed.

"Reiki in the Air Extraction Project"

Since Yang Yu came to this world, he has been thinking about a few questions in his heart.

1. What exactly is Reiki?

2. Since there is aura in the air, how do you purify it?

With these questions in mind, Yang Yu drew drawings and then asked someone to secretly create some chemical experiment utensils, and after linking them, he collected a large bottle of air.

In the first step, the air is passed through the caustic soda solution to remove carbon dioxide, then the next step is to remove oxygen through a special solution, and then the next step is to remove nitrogen, so that after a series of chemical reactions, only a few small bubbles are left in a small glass bottle upside down in the water.

If it was in the earth's atmosphere before the crossing, the remaining gases were all kinds of inert gases in the air, and in the immortal cultivation realm after the crossing, this last bubble was tested by Yang Yu, and there was also aura, and it was equivalent to the aura purified from the air of the size of several water tanks.

Its aura concentration is relatively high, and after measurement, it occupies almost 38.8% of the remaining gas volume.

With the idea of extracting the aura in the air, Yang Yu soon established the next scientific research project.

How to Purify Reiki on a Large Scale

It is indeed possible to use the chemical reaction method, but first, the efficiency is low and the preparation is troublesome; Second, there are a large number of rare gases in the purified gas, and the purity is not high.

This question puzzled Yang Yu for several months, and finally after a long period of studying in the Heavenly Tower, Yang Yu found a way.

Air compressor!

An air compressor driven by a generator continuously draws air in, and then compresses the volume into liquidized air.

Then slowly reduce the pressure in the container, and separate the different components in the air through two steps of gas liquefaction and fractionation, and in this way, Yang Yu obtained an almost endless amount of high-purity spiritual liquid.

The most gratifying thing is that the aura will be very stable after being liquefied by the compression method, Yang Yu has been tested, between -200 and 300 degrees Celsius, although it will produce a lot of crystals at the bottom of the bottle because of the high concentration of the spiritual liquid, but the aura is generally still liquid.

Therefore, you only need to slowly heat the liquid air to room temperature, and what is left in the container is 100% pure spiritual liquid!

The past flashed through Yang Yu's mind quickly like a slide, and when the memories were finished, Yang Yu also ended holding his breath.

"Whew! ~~~~”

It's cool to take a spiritual bath, I think I'm afraid that those great sons and daughters of the Holy Sect are not as luxurious as me!

Naked out of the bath bucket, a lot of spiritual liquid fell to the ground with the sound of rushing water, and Yang Yu was not distressed.

Only occasionally, he would mix it with water and put it into a small bottle, and then sell it through the secret market to buy some elixirs and other immortal cultivation materials.
