After returning to Shiping Mountain and saying goodbye to Jiang Li'an, Wei Dongliu went to check on Guo Jin's condition.

At this time, Guo Jin was sitting upright on the stone bed, posing a Qi-refining posture with his five hearts facing the sky, breathing in and out slowly to open up his Qi sea.

The Ca Nu Su Yin Needle that Jiang Li'an gave him was wrapped in black cloth and placed on the stone table next to him. It seemed that it had not been touched since he came back.

He ate a part of the thousand-year-old Polygonum multiflorum that Wei Dong gave him before he left the mountain, and left the rest in the basin untouched - this aged Polygonum multiflorum is the most resistant to hunger and is also very good for fasting.

The "Sutra on Eliminating Demons and Separating the Clear and Turbid" by Taiyi Tongxuan Zhenren also includes the method of fasting and refining qi.

This kind of basic entry step is basically the same for all major sects. Even Kunlun's Qigong method of fasting and refining is not much more advanced.

After confirming that Guo Jin was still practicing hard, Wei Dongliu leisurely returned to his room, also put on the posture of five hearts facing the sky, and practiced his mental method.

He himself was already at the Transformation Palace Stage, and after practicing the mental method of "The Sutra of Eliminating Demons and Separating the Clear and Turbid" for a while, he felt his Qi sea suddenly become heavy, as if a weight was hanging in his lower abdomen.

Nowadays, whether it is the Three Pure Ones of the orthodox religion, the Six Paths of the evil religion, as well as Buddhism, Confucianism and other unorthodox ways, there are thousands of ways of breathing, but in essence they are all about refining turbidity into purity.

That is, the turbid air in the body is refined and expelled, and fresh air is absorbed from the outside world to replenish it and continuously purify it.

The reason is very simple: the clear air is ethereal, while the turbid air is heavy.

The former is light and agile, and can be refined into true qi to drive magic, improve physical fitness, enhance realm, etc.

The latter is turbid and like mud, it is difficult to move and cannot be used.

As for these foul airs, the orthodox teachings often discard them and expel them completely.

However, the evil cults often retain a very small amount of turbid air, and use magic techniques to purify and refine it into demonic energy, which they carefully accumulate within the sea of ​​qi. When necessary, they use their true qi to wrap it up and send it out, and use it in conjunction with their techniques to hurt people.

This so-called evil spirit is tens of millions times more inert than turbid air and is extremely difficult to remove, just like snake venom:

If it comes into contact with a magic weapon, the weapon will be polluted by the spiritual power and become uncontrollable; if it hits a monk, the monk's meridians will be blocked and his cultivation will be lost... It is an extremely vicious way of fighting.

Not long after, Wei Dongliu used the "Sutra on Eliminating Demonic Spirits and Separating Turbidity from Purity" to reverse his practice, causing all of his true energy to transform into demonic energy.

If it were an ordinary demon cultivator, it would be impossible to do this. This Jade Mansion is 100% demon essence, and the Dantian would have burst and died long ago.

But Wei Dongliu has a chaotic demonic body. Any demonic energy in his body can flow freely like pure air... the same is true for the demonic essence condensed from demonic energy.

After the transformation was completed, Wei Dongliu stood up and looked into the bronze mirror.

As a result, I was shocked.

I saw that the person in the mirror had handsome and distinct facial features, with no change in size or position.

However, the irises of his eyes turned from brown to inky black, and his hair turned from jet black to dark red. Although his skin color became darker, he did not have the sickly feeling of "lack of blood color". Instead, he had a bit more evil and unruly meaning.

What a cool and handsome demon king!

"Tsk tsk tsk." The Kunlun Mirror did not speak in the sea of ​​consciousness, but just made a "tsk tsk" sound.

Wei Dongliu knew that Ah Jing was mocking him for being "self-praising" and "shameless", so he said in a deep voice:

"What's so good about this? Such a handsome and charming demon king, Ah Jing has never seen one before?"

"Okay, okay, whatever you say is what it is." Kunlun Jing said helplessly.

Wei Dongliu was too lazy to pay attention to it. He just tapped the air with his left hand several times to set up an isolation formation.

He raised his right arm and waved his hand, and the Ten Thousand Demons Evil Sword flew up from the table.

The hilt of the sword fell into his palm, and rich demonic energy poured into it. Immediately, the sound of thousands of ghosts wailing was heard.

All I could hear was a voice that sounded like resentment, longing, crying and complaining. Every word was pleasing to my ears and shocking to my soul.

Even though Wei Dongliu had great self-control, he could not stand the sound of the ghost crying, and only with the help of the Kunlun Mirror did he calm down.

Good thing! This Ten Thousand Ghosts Sword is indeed an eleventh-level immortal sword! Without anyone deliberately activating it, even the lowest-power Ten Thousand Ghosts Howl can hit a cultivator like me at the Transformation Palace level.

If I exert my full strength, wouldn't I be able to fight against a Jindan Zhenren?

"It's quite good for sneak attacks." Qingping Sword said.

"Qing Ping." Wei Dongliu laughed in his heart. I have been waiting for you to speak. "This sword is good in other aspects, but the sound of the wailing of thousands of ghosts cannot be controlled freely."

"I can't cry so loudly that people within a radius of dozens of miles can hear me every time I draw my sword, right? My mysterious personality is about to collapse... Do you have any way to help me treat this Wan Gui Xie Jing Sword, just like you did with the Lei Zheng Sword last time?"

"Your sword has no sword spirit, how can I kill it?" Qingping Sword said with a laugh.

"No sword spirit?" Wei Dongliu frowned, his eyes suddenly sharpened, "How can an eleventh-level immortal sword be without a sword spirit?"

"First of all, there is no such thing as an eleventh-level immortal sword." Kunlun Mirror added, "Secondly, not all immortal swords have sword spirits."

"That's right." Qing Ping Sword echoed, "If I'm not mistaken, the previous owners of this sword never took good care of it."

"The sword master is ruthless, so where does the sword spirit come from?"

"In that case." Wei Dongliu still refused to give up and continued to ask, "There must be other ways to block the wailing of all the ghosts, right?"

"To block the wailing of ghosts, you must at least know why there is crying." Qingping Sword said calmly, "This sword is forged with Netherworld Yin Iron and washed with Yellow Spring Water. Both of them have extremely strong soul-binding abilities."

"You mean..."

"The so-called crying sound is the sound of the souls of the countless creatures that died under this sword and were plundered by it." Qingping Sword replied, "Because the number is so huge, the combined sound can shock the mind and scatter the souls."

"If you want to block out these cries, it's very simple... Find some red lotus fire to burn them for a few days, kill all the souls inside, and the cries will naturally stop."

"How can this be possible?" Wei Dongliu didn't know whether to laugh or cry. "I'm not trying to eliminate the howling of ghosts. I just want it to become controllable from being uncontrollable."

"In other words, it can only cry if I tell it to; if I don't tell it to cry, it will shut up and not make any sound."

Qing Ping Sword: ...

It's really troublesome to meet a sword master who always makes unreasonable demands...

"It's not that there is no solution." Qing Ping Jian pondered for a long time and sighed, "These souls don't have much consciousness. They are just driven by the remaining pain of death, so they cry."

"However, death is not just about pain, it is also about great fear."

"You only need to use the energy of the five metals to penetrate the sword, and these souls will be frightened and stopped, so that they dare not make a sound."

"So that's how it is." Wei Dongliu said as if he had suddenly realized something. "Then, what is 'the Qi of the Five Metals'? And what is 'penetrating through the sword'?"

"The energy of the five metals is the energy of killing." Qingping Sword said helplessly, "You can use your Shaofu Shangyang sword energy."

"As for the sword-piercing technique, I have a technique called 'Spiritual Seal Sword Technique' that can attach Taoism to a flying sword. Listen carefully..."

"Yes, Qingping, you go ahead." Wei Dongliu immediately perked up and began to listen to Qingping Sword's explanation of the method.

As expected, if you have any questions about external affairs, ask Ajing; if you have any questions about internal affairs, ask Qingping!

With their help, why worry about finding the right path?
