Li Wuding, who returned to the inn, hurriedly took out the two pieces of black jade and participated in the study.

The first thing he studied was the cultivation method of concealing evil qi, which was called "Washing Evil Qi".

After reading it, he also used AI to make some calculations, but unfortunately, because the data flow is not enough, AI can't analyze the reason.

However, AI does give a reference.

The purpose of this set of exercises seems to be to simulate the wavelength of spiritual power fluctuations by artificially changing the wavelength emitted by evil energy, so as to achieve an effect that looks equivalent to spiritual power fluctuations.

This view coincides with Li Wuding's view.

The method of improvement is also ingenious, that is, by adjusting the frequency of the crystal nucleus to release evil qi, as much as possible to simulate the release of true qi.

Li Wuding's evil qi operation is carried out in the way of light evil qi, so it is easier to control, just need to convert the crystal nucleus into a filter, and release the light evil qi that "meets the required wavelength" into the meridians, and the wavelength that does not meet the requirements is automatically isolated, and it can almost be done with the fake.

With a little practice, Li Wuding had a very slippery game.

However, he also regretted to find that with such a filter, the power of the Qigong method would be discounted by almost half.

Thinking about it now, it was indeed a bit strange that the aura fluctuations on Condensation Yao's body were a bit strange, but what was wrong, he couldn't tell, it turned out to be an "improved" wavelength.

However, he didn't care too much about this, because his true qi was the main output of the exercises, and now adding half of the light evil qi output was equivalent to adding some power in plain vain.

Now his evil qi cultivation is still relatively low, only the first level of qi cultivation, if his evil qi cultivation increases a little more, he can provide a lot of cultivation help.

"Bah, big bird, don't increase your evil qi!" Li Wuding thought depressedly, he came to the extreme northern tundra with great hope this time to seek a way to clear the evil qi, how could he turn around and turn it into an increase in evil qi?

If the evil spirit continues to increase, won't you have to eat an elephant for every meal?

But that's not right, if the monks of the Demon Realm were all eating like this, the Demon Realm would have been eaten into a desert a long time ago? Where could there still be spirit beasts?

It seems that next time I have to ask Condensation Haruka, whether he overeats every meal.

Looking at the other black jade slip in his hand, Li Wuding hesitated, did he want to look at this demon-like exercise?

Let's see!

Knowing more about the exercises related to evil qi may also help you clear these evil qi yourself.

The evil spirit soaked into the black jade slip, and he copied the contents into the biological computer.

This is a set of exercises called "Heavenly Dream Dragon", which is known as one of the top ten exercises in the demon world.

Judging from the introduction, it is divided into nine layers, and what he has now obtained is the first layer, which vaguely mentions that this is a top-level exercise of the Demon Realm Black Mountain Sect, and when it is cultivated to the top, it has the effect of "moving mountains and reclamation and opening up the world". There is a book shortage

However, it is a pity that from the sixth layer onwards, the upward exercises have been lost.

Even so, this set of "Heavenly Demon Dream Dragon" is still the first systematic Demon Realm Exercises that Li Wuding has obtained, and the Demon Realm Black Jade Janes that he copied in the Beihai Kingdom Royal Library before are too fragmented, and they seem to be very profound, but they can't systematically introduce the Demon Realm Exercises.

Li Wuding used artificial intelligence to read and analyze all the way, and finally generally understood what evil qi was and how to use it to cultivate.

Evil Qi is actually the same as Spiritual Qi, it is a special energy body, just as Condensation Yao said, the spiritual realm cultivator does not know that cultivating with Evil Qi is indeed a tyrannical thing.

If the aura is alcohol, then the aura is gasoline, and the aura needs to be transformed into true qi or spiritual power by the monk through the transformation of the dantian qi sea before it can be used, and the evil qi can basically be used directly, which makes the cultivation of the evil qi much faster than the cultivation of the aura.

However, there are pros and cons to everything, and although the cultivation speed of evil qi is amazing, it is also very damaging to the human body.

The evil qi that has not been transformed runs in the dantian qi sea and meridians, and the stimulation and damage to the human body are like rough sand rolling in the meridians, especially when the high-level monks release the exercises, the damage is like a knife scraping fire, and probably only the strong physical fitness of the demon realm monks can bear it, and the human race monks can never afford it.

Therefore, Condensation Yao just checked out that Li Wuding had a bad spirit, and immediately identified his identity as a "remnant of the Holy Realm", which really couldn't be faked.

In the same way that the spiritual realm monks cannot practice the evil qi exercises, the demon realm monks cannot rely on the aura to cultivate, and it seems that the aura is very "gentle" and does not seem to cause harm to the demon realm monks.

In fact, due to the different frequencies and other methods of energy, the harm of aura to the demon realm cultivators was also very huge, so Condensation Yao and they chose to stay in a place where the extreme northern tundra was very rich in evil qi.

Seeing this, Li Wuding was even more strange, not only was he not the so-called "Remnant of the Holy Realm", he was not even an authentic spiritual person, but he was from a distant earth, how could he accommodate both spiritual energy and evil energy?

After all the calculations, only his strange so-called "Heavenly Dao Spiritual Root" can explain it.

In addition, the exercises of the demon realm are also very different from those of the spirit realm.

The exercises in the spiritual realm generally separate the basic exercises from the offensive and defensive exercises, and only after laying a solid foundation do they begin to practice the offensive and defensive exercises.

And the Demon Realm Exercises are "two in one", and the two are improved simultaneously, which is probably related to the direct use of evil energy, so the Demon Realm Exercises are simple and direct, there are not so many twists and turns, and the difficulty of cultivation is much lower than that of the Spirit Realm Exercises.

Li Wuding only practiced with artificial intelligence a few times, and he was familiar with it, but he didn't plan to cultivate.

He was very worried, once this thing was cultivated, it would be like a leech's upper body, it would be easy to practice, but it would be difficult to get rid of it!

Dazedly rubbed the two pieces of black jade into powder, and then threw them into the toilet, Li Wuding didn't know what he should do next.

The biggest purpose of his trip seems to be frustrated, which makes him feel a deep sense of powerlessness, this damn evil spirit!

Since the evil qi can't be removed temporarily, then go mining, so let's complete the task first, and then talk about it, by the way, look for it, there is the most aura, suck him up!

Early the next morning, Li Wuding rushed to the communication wall to check the news, but it was a pity that there was still no reply from Du Yanyu, and he didn't know what was going on over there, maybe her mother's situation was really bad, and she couldn't leave it for a moment.

However, in the bottom of his heart, Li Wuding faintly felt that things didn't seem to be so simple, this seemed to be a well-arranged "bureau", and he couldn't help but sweat for Du Yanyu.

He sent a message to Du Yanyu again: How is the condition of the aunt and whether she needs any help. Also, I'm fine here, don't worry. Hope for revenge.
