When Zhang Xuan showed up, the Demon King faintly realized what was happening, and hurriedly came to him and said, "Master, you can even play tricks on the master ghost hunter, it's really amazing!" ”

"Hmph, pretending to be a garlic expert, it's a big deal!" Zhang Xuan said disdainfully.

With the help of the Immortal Codex, he really can't look down on the so-called ghost hunting experts and the like.

Next, he continued to browse and consult the Qi Dictionary of the Immortal Classics.

According to the description of the Qi Codex, Qi is also divided into endogenous Qi and Exogenous Qi. The endogenous qi is the qi that people bring from the mother's womb, which can arise and grow on their own. From the perspective of application, these endogenous qi can be divided into four stages, from low to high, such as nourishing qi, luck, resisting qi and transforming qi.

The so-called nourishing qi refers to the germination, growth and nourishment of endogenous qi. Hair growth and growth are automatic and depend on the functioning of the human body, but nourishment is a conscious action of people. For ordinary people, being good at cultivating qi is a relatively high realm.

However, people in the martial arts or immortal path pay attention to the use of endogenous qi, so there are theories of luck, imperial qi and qi.

Luck is the primary use of endogenous qi, and what the martial artist calls luck and strength is luck and luck. A more advanced form of use is the Imperial Qi, and the main body of the application has a higher ability to control the endogenous Qi. Transforming qi is the use of endogenous qi, sublimating and changing its form, from real to virtual or from virtual to real, virtual in real, real in real.

Under normal circumstances, martial artists can only master the method of luck, but they cannot control qi, let alone turn qi. Immortals can usually only master the methods of qi control and the following, and do not have the skills of qi transformation.

The skills of using the above three kinds of endogenous qi are all embodied in the two behaviors of collecting and releasing it, but the actual effects are very different, and even very different.

Endogenous qi can not only be used alone, but also mixed with force, or used in combination with qi and force, or with qi to resist power. The energy formed by the fusion of qi and force is usually more powerful than a single energy, and the attack or defense effect is better.

The external qi is the qi of all living beings, the qi of the rivers and mountains, the qi of the grass and trees, and the qi of heaven and earth, such as wind, rain, thunder and lightning, warmth, cold and heat. The qi of heaven and earth also contains the qi of chaos and evolution, of which the qi of chaos is the qi that sprouted when heaven and earth were first born, full of energy and more powerful.

It would take a lot of work just to understand these different types of qi, but Zhang Xuan didn't have any impatience, but watched it with relish.

Of course, his focus is on how to use these different types of qi, and how to combine the use of qi and force, compare the similarities and differences between them, and analyze the ways in which they fuse.

According to the Qi Codex, each body unit of a person is a sea of qi, but due to the lack of excavation, people usually only think that there is only one sea of qi in their body. Compared with tens of thousands of gas seas, the gas storage capacity of one gas sea is not half a star, so the ability to collect and release all qi is also far behind.

Seeing such a statement, Zhang Xuan's eyes almost popped out in surprise.

For a martial artist or an immortal, a sea of qi can release such a strong qi, if each body unit becomes a sea of qi, how much qi does it have to store and how much strength does it have to grow?

If such a statement comes out of the mouth of an ordinary person, then he will definitely not believe it.

Xiandian said this, but he had to believe it.

Surprised, he carefully read the contents of the Qi Dictionary several times, and then began to carefully comprehend it.

He didn't understand some of the rituals in the meantime, but fortunately, with the help of Hongrui and Bamboo Soul, he finally understood.

When he was helping him to go through the details, the bamboo soul opened his mouth and asked, "Zhang Xuan, do you have any doubts about the Immortal Dian's statement about the Qi Sea?" ”

"Well, it's a bit skeptical, but I have to believe it because of its authority." Zhang Xuan replied with a bow.

"If you are suspicious, you can't say that it is abnormal, but according to me, your suspicion is not very reasonable. I am a spiritual being, and I know that everything in the world is spiritual, and their original spirituality can be deeply developed. If spirituality can be developed, why can't the qi storage function be developed in depth? Bamboo Soul said.

"Ah, indeed. Even if you say so, I can only develop according to the description in the fairy codex. If I develop it well, then I will become stronger. It doesn't matter if it doesn't work. ”

Zhang Xuan responded.

Bamboo Soul's words made him more aware that his physical potential could be deeply developed. Prior to this, he had succeeded in developing his hidden primordial powers, which had increased the power he could wield many times over. Now, he's set out to develop his latent energy, and if he succeeds, he'll undoubtedly get stronger.

Only a stronger self can calmly cope with all kinds of difficulties and obstacles encountered in the future.

Through more than ten days of hard work, he made some progress in developing the Qi Sea, but he failed to reach the ideal level mentioned by the Immortal Classic. He realized that such things had to be done gradually, and could not be done overnight.

During this period, he mastered all the exercises that used both the inner and outer qi, and it was a complete harvest.

In order to test the effectiveness of those exercises, he came out of Xiaoqiankun, found the four demon kings, and said with a smile: "Everyone, how about we play a game?" ”

"Huh?" The Demon King was shocked when he heard this, "Master, you have always been busy with big things, why did you suddenly want to play games with us?" We've always been stupid and don't know how to play games. ”

Zhang Xuan smiled: "Don't worry, I won't play those complicated games with you." It's a very simple game, you stand here, I make some cyclones, you just use your magic powers to escape from that cyclone. As long as you can escape, it is a success. Whoever manages to escape, I reward it. ”

Ah, playing such a simple game, and with a reward, that's no problem. Anyway, we're all big demons, can't we get rid of those cyclones?

Thinking like this, the four demon kings were happy in their hearts, and their faces bloomed with smiles, and they all nodded in agreement.

Zhang Xuan glanced at them with a wicked smile, and immediately drummed out some cyclones, enveloping the four demon kings.

The four demon kings were full of confidence at first, but when they were covered by the cyclone and wanted to get rid of it, they immediately realized that something was wrong. Those cyclones don't look like they're powerful, but they're powerful, and they seem to have eyes, and they follow wherever they go.

And, later, the cyclones somehow had a rhythm, and they could only dance to the rhythm of the melody.

Heck, this game looks extremely simple, but it's very difficult to play, let's talk about what rewards we get from getting rid of cyclones, it's good not to be tired from dancing!

At this time, the minds of the four demon kings came to a big reversal.

Zhang Xuan watched the demon king dance, and said with a smile: "Ah, man, you claim that you don't know how to play games, obviously you are lying to me." Even dancing so well, extremely rhythmic, how can you not play games? ”

When the four demon kings heard this, they were very angry in their hearts, but they couldn't argue with Zhang Xuan, so they had to continue dancing silently.

After about a meal, Zhang Xuan put away the cyclone and asked the four demon kings, "Everyone, what do you think of such a magical power as me?" ”
