More than two hours later, Liu Yu returned to Cailian Mountain.

After putting away the magic weapon, he opened the formation and walked in. He saw Ji Ruyan playing with some flowers he had picked.

"Son."

Ji Ruyan stood up, saluted and said respectfully, but then there was no follow-up.

She knew that she was just a maid now, she only needed to do her own thing well, and don't ask questions that shouldn't be asked.

Liu Yu nodded slightly in response. He felt the woman's aura and found that she was not far from the ninth level of Qi Refining. At the current speed, it shouldn't take more than a year.

Everything is going in the direction he envisioned, and when he reaches the ninth level of Qi refining, he will be given dragon blood fruit to strengthen his physical body.

One year to refine the nine levels of Qi, two years to refine the Qi to the peak, and another year to polish the mana, at most four years will be enough to build the foundation.

This woman's talent is better than mine, and with the help of the elixir, her speed can be even faster than mine.

With this in mind, Liu Yu entered the practice room and sat cross-legged on the futon.

It has been determined that there is nothing wrong with Canglang Lingshui, so it is cheaper to get rid of the erysipelas sooner rather than later.

Although the impact of erysipelas on the cultivation speed is still very small, and the biggest impact is when hitting the bottleneck, but with his qualifications, it would be good to increase the cultivation speed a little.

This is also the reason why Ji Ruyan is so valued.

He took out the jade bottle containing Canglang Spiritual Water, uncorked the bottle and controlled the water flow to fly out automatically. Within a few breaths, all the spiritual water would fall into his belly.

Liu Yu did not dare to be careless, closed her eyes and quickly pinched the magic formula, and began to refine the potion.

And deliberately use magic power to carry the medicinal power and bring it to every part of the body, striving to maximize the effect.

Soon, it was just like what was tested on Yuan Wanli and Xu Kang.

An icy cold feeling came, and the medicinal power spread to every part of the limbs including flesh, blood, meridians, and bones, and began to take effect.

A layer of gray-white impurities is gradually eliminated from the inside out.

Perhaps because of the aura cleansing during foundation building, Liu Yu discharged far fewer impurities than the two of them, and the odor was not that strong.

After a quarter of an hour, the cold feeling gradually disappeared. Instead, a hot burning sensation slowly spread throughout the body.

Down to every drop of blood, down to every part of flesh and blood, down to the depths of the bone marrow.

"Uh-huh"

Liu Yu, who closed her eyes tightly, let out a groan of pain, then frowned.

This kind of pain that spreads all over the body is not much different from the pain of refining the gods. At this moment, he finally realized what Xu Kang and Yuan Wanli experienced.

The pain of refining the gods has been reduced by more than 90% since he started cultivating the gods. Liu Yu has not felt this extreme pain for a long time.

Gather your energy and concentrate your mind, hold your essence and keep it together.

Liu Yu worked hard to keep her soul clear, and gradually entered a strange state.

His soul and consciousness seemed to be elevated, and he was in the state of a bystander, calmly observing everything that happened to his body.

In this state, even the physical pain seems to be far away, and the consciousness remains absolutely calm.

The Yuan Shen controls everything in the physical body and observes the progress of the washing. The erysipelas is gradually eliminated and turned into a dark substance and expelled from the body.

After another quarter of an hour, the dark substance gradually ceased to be discharged, and the medicinal power of Canglang Spiritual Water also disappeared.

With a thought in mind, I opened my eyes and felt a cold feeling.

Only then did Liu Yu realize that her long hair was sticky and stuck to her skin, and she was sweating profusely without realizing it.

The skin under the robe was covered with two kinds of substances, gray and pitch black, emitting a strong stench, which was even three times worse than what I had smelled under the swamp of Bingliu Medicine Garden.

After looking inside his body and finding nothing out of the ordinary, he quickly stood up and left the practice room, entered the bathroom, and began to wash his body carefully.

"call"

The magic power shook off the impurities, and after being rinsed with clean water many times and put on a brand new robe, Liu Yu breathed a sigh of relief and felt much more comfortable.

Then he returned to the practice room, swallowed the elixir and started practicing.

Five hours later, Liu Yu, who had completed his daily practice, opened his eyes and showed a smile.

After the erysipelas was eliminated, the speed of cultivation really improved a bit.

Although the magnitude is not large and no effect can be seen in a short period of time, it is still very impressive when calculated on a yearly basis.

As for the effect of improving qualifications mentioned in the formula, it is just to remove acquired impurities from the body, which is equivalent to improving qualifications.

However, Liu Yu had already been cleansed with spiritual energy when he was building the foundation, so his physical qualifications had only improved in an insignificant way.

If spiritual root qualifications are so easy to improve, why do various sects value spiritual root qualifications so much?

…

A peaceful period followed, and the months passed quickly.

Cailian Mountain Cave Mansion, in the training room.

A monk with an ordinary face sat cross-legged on the futon. It seemed that he had reached a critical moment in his cultivation, and big beads of sweat rolled down his forehead.

This person is none other than Liu Yu!

In the realm of foundation building, Qingyang Kung requires nine times of thorough demonic fire refining to refine the mana, making it more pure and refined, thereby increasing the chance of forming a pill.

This secret technique has advantages and disadvantages. Although it allows those who practice the technique to have a 10% higher chance of forming an elixir than other monks, it will undoubtedly slow down the speed of cultivation.

It doesn't mean that you can't practice Qingyang Kung if you don't practice the secret technique of demon fire refining essence.

But in that case, the advantages of the technique will be greatly weakened, and it will not be much better than ordinary techniques.

When refining the essence with magic fire, you can also do it less thoroughly, or you can do it less often.

But in that case, the final effect will be greatly reduced.

It is basically impossible for an ordinary monk to practice Qingyang Kung and go through nine rounds of demon fire refining to reach the peak of foundation building.

I'm afraid that the bamboo basket will be empty by then, and I won't be able to reach the peak of foundation building until I die.

Only monks with excellent spiritual qualifications or deep resource support are the best candidates for practicing Qingyang Gong.

With the support of the Immortal Mansion, Liu Yu chose the most difficult path with the greatest potential.

A quarter of an hour later, the speed of the magic formula in his hand became slower and slower, Liu Yu's expression gradually calmed down, and finally he opened his dull eyes.

The fourth magic fire refining!

Feeling the magic power running three points faster in the Dantian of his meridians, a hint of joy appeared on his face.

After the fourth round of magic fire refining, the magic power became even more pure.

One serving is equivalent to 1.2 servings as before. A smaller portion can ultimately produce greater power.

At the same time, the speed of operation is also two minutes faster than before. It can activate the magic weapon faster and respond to various situations faster than monks of the same level.

Overall strength has increased by almost 20%.

After feeling the changes brought about by the magic fire refining essence for a while, Liu Yu calmed down.

Run the invisible spirit technique, and converge your own cultivation, aura and spiritual pressure to the level where you have just broken through the middle stage of foundation building.

That's right, he plans to reveal to the outside world that he has broken through to the middle stage of foundation building.

With the qualifications of the Three Spiritual Roots and the skills of an alchemist, it took nearly twenty-five years to break through to the first level of cultivation, which is quite reasonable.

This advancement speed is much faster than that of ordinary foundation-building monks, but considering that the alchemist's net worth is richer than that of ordinary monks, he must take more pills than ordinary monks, and he practices ordinary skills that advance faster.

It also seems very normal.

Appropriate display of potential and strength is more conducive to development in the sect.

Although the status of a second-level alchemist is higher than that of most foundation-building monks, he is still a heretic. Many monks may be polite on the surface, but in fact they may not take it seriously.

But the real realm is different. It is something that is valid under any circumstances and will not change due to changes in the environment.

The realm of the middle stage of foundation building is very delicate. Liu Yu can practice to the middle stage of foundation building at the age of just over fifty, so the possibility of being able to break through the golden elixir bottleneck is naturally greatly increased.

In the eyes of some monks, the value is naturally different.

The higher your status, the more power of the sect you can draw on, and it will be easier to do things, whether it is collecting various spiritual herbs or doing other things.

After getting up and leaving the practice room, washing her body, Liu Yu entered the bedroom and quickly fell into sleep.

The next morning, he woke up leisurely, and all the energy and energy he had consumed had been restored.

After washing and tidying up her clothes, Liu Yu put on a green shirt and prepared to leave the cave.

Today is the day that Master Li Changkong said that he and his senior brothers and sisters will get to know each other.

Passing by the hall, Ji Ruyan was holding a book and looking at it intently, when he saw Liu Yu appear and salute with a smile.

After getting along with him for a period of time, she had gotten to know "Young Master" somewhat, and she was no longer so restrained, and it became much more natural to stay in the cave.

Liu Yu nodded slightly and walked out without saying anything else.

He was quite satisfied with Ji Ruyan's cultivation speed. After more than half a year, this woman had reached the peak of the eighth level of Qi refining, and was only one step away from the ninth level of Qi refining.

He walked out of the cave and sacrificed his magic weapon, which turned into a black light and rose into the sky, flying straight towards Tongtian Peak.
