After Dugujing and the three confirmed their safety, Liu Laoliu and the coachman were reincarnated like starving ghosts, gobbling up and eating their fill, and then went into the room to rest, and died comfortably. A few people have been really nervous these days, and a little relaxation and sleepiness will hit them immediately.

But the three of them didn't dare to ignore it like Liu Laoliu and the others, and after discussion, they decided that each person would take turns to take a nap, leaving one person on duty each time, Dugujing said that he was duty-bound as the first person on duty, so that Ayao and Du Xi'er could rest.

Moved a stool and sat outside the door for a while, Dugujing threw the stool and began to meditate, just closed his eyes, Du Xi'er slowly walked behind him.

"Why doesn't Miss Jean go to rest?"

"How does Dugu know it's me?"

"The sound of the girl's footsteps is peculiar. ”

Du Xi'er helped the stool up and sat beside him, and was silent for a moment before saying, "I will change A-Yao's predecessor for a while, I still have time to rest, and I can't sleep for the time being." I suddenly remembered that I forgot to tell you something about internal strength, so I came over to tell you. ”

Two days ago, Du Xi'er had handed over all the internal strength mantras to Dugujing, and Dugujing had almost memorized them, but because of the bumps on the road and the hunger in his belly, he never tried to cultivate, and he didn't try it for the first time until he had time now.

Dugu Jing opened his eyes and looked over, and Du Xi'er continued: "Once this exercise is practiced, the internal skills that Gongzi cultivated before will be gone. ”

"This ...... It's the first time I've heard of this exercise, is there anything special about this exercise?"

"Yes and no, this has to start with the characteristics of internal strength, many exercises have different natures, but they all avoid talking about this matter, this experience is often passed on by the master and the apprentice, and the end of the second chapter makes a detailed classification of this matter. Because I didn't have a foundation of internal strength when I was practicing, I didn't have to worry about it at all, so I forgot to tell my son. ”

Dugujing understood what she was talking about: "I also have some understanding of this matter, some people's internal strength has yin and yang changes, I know that the most famous is the cold wind, this predecessor is called cold wind, and the internal strength is also extremely cold." For example, my internal strength is just the opposite, and I am taking a fierce road, could it be that the internal strength of the second chapter of this "Secret Record of Martial Arts" has a special change?"

Du Xi'er shook her head: "What you said is not right. ”

"Then I would like to ask Miss Qin to introduce me. ”

"Internal strength is generally only hot and cold changes, so people in the rivers and lakes use the words yin and yang to represent cold and hot respectively, but this method of distinguishing is somewhat limited and difficult to fully generalize, so the master and the master discussed and re-distinguished.

Yin and Yang are only used to distinguish the characteristics of internal strength, and the attributes of heat and cold are replaced by fire and water in gold, wood, water, fire, and earth. Although this still can't accurately summarize the internal strength of the various sects and factions in the world, it is also slightly better than before. ”

"I still don't understand it below. Dugujing scratched his head.

"Yin and Yang are the characteristics of internal strength, Yin represents darkness, this kind of internal strength is often continuous, very penetrating, and people are unable to guard against it, while Yang is the complete opposite, this kind of internal strength is dominated by extremely high bursts, and they are all fierce all the way. ”

"This is a little clear, the internal power under is yang, is it the internal power of the second chapter of "The Secret Record of Martial Arts" is yin, so I don't know how to explain water and fire?"

"That's right, my internal strength does belong to yin. This water and fire is actually not difficult to understand, it represents the difference between cold and heat, the internal power of yang can have the attribute change of water and fire, and the internal power of yin can also have the attribute change of water and fire. ”

In this way, there are four different distinctions of internal strength. ”

"No, it seems that Dugu Gongzi still doesn't understand. ”

Zai Xia thought he understood, but Miss Qin's words made Zai Xia confused again. Dugujing was puzzled, so he could only say helplessly.

Du Xi'er stood up and asked, "Dugu Gongzi still remembers what are the characteristics of Yin type of kung fu?"

"It's endless, it's very penetrating, it's hard to guard against. ”

"Yes, Childe came and looked. ”

Du Xi'er walked to a tree not far away, and Dugujing hurriedly followed. I saw Du Xi'er come to the tree, raise her hand, and slowly press it with a palm......

There was no change in the tree, and Du Xi'er's internal strength spit out again, only to hear a "bang" sound coming from another time in the tree. Dugujing stretched out his head to see that the bark on the other side of the trunk was broken, and the exposed trunk was also broken, exploding the big scar at the mouth of the bowl.

"Good kung fu. Dugujing clapped his hands.

"This is yin, but ......" Du Xi'er coldly slapped Dugujing directly.

Dugujing was stunned for a moment, this palm was not only slow but also extremely powerful, knowing that she didn't really want to do it, so she raised her right arm and took it, and suddenly a cold air hit, making Dugujing shiver.

"Come again. Du Xi'er didn't stop, and slapped again.

Dugu Jing still took it with his right arm, and then his eyes widened, this time it turned out to be a rich heat wave, which instantly melted the previous cold air, leaving a scorching heat.

"Therefore, there is only yin and yang in internal strength, and there is no difference between water and fire, which is the difference between the internal strength of the Absolute Valley and the internal strength of other sects. ”

"Does that mean that the internal strength of the fierce masculine all the way may also use the effect of yin to cold?" Without waiting for Du Xi'er to answer, Dugujing found the error in his words, "You can use the effect of extreme cold, but it is not 'yin', but yang to cold." ”

"Everything. ”

Du Xi'er raised a palm, and this time the sound sounded when her hand touched the trunk, and there was a "bang", with Du Xi'er's hand as the center, the bark was broken and the trunk was broken.

The fierce destructive power of "this ......" seems to be different from the previous statement.

"The difference between yin and yang is only the difference between internal strength itself, although they are incompatible with each other when cultivating, it does not affect how you use it, don't be limited by these statements. ”

"And what is this distinction between yin and yang for?"

"In order to judge whether the two internal exercises can coexist, it is possible to judge whether the two exercises can be practiced at the same time. This is different from the rumors in the rivers and lakes, such as the same internal strength as yang, although one is cold to cold, and the other is rigid to hot, but it can be cultivated at the same time. ”

"I see, the classification of yin and yang is not surprising, but this statement is really unheard of. ”

Originally, it is not surprising that the classifications of yin, yang, femininity, and fierceness are not surprising, but in the eyes of people in the rivers and lakes, one is cold, and one is hot, which must belong to two completely different internal strengths of yin and yang, and Du Xi'er's statement is indeed special.

"Then the internal strength is yang in the lower level, and the internal strength taught by the qin girl is yin, so the original internal strength needs to be dispersed when practicing in the lower stage?"

Dugu Jing was a little worried, he didn't want to scatter his family martial arts, even if he didn't practice well, even if the martial arts of the Absolute Return Valley were stronger, he didn't want to, but he didn't expect Du Xi'er to shake his head.

"I can't say this, but I'll understand when I'm done. ”

Lonely spot head.

Regarding this distinction between yin and yang, Master said that it was too simple, because after so many years in the valley, I found that although the internal skills practiced by different sects in the rivers and lakes belonged to the same category, they were sometimes incompatible. And this incompatibility is irregular, and it may not be the case for different people.

This discovery is also an accident, a person was inadvertently injected with a force of internal strength by the other party when competing with others, this kind of thing is not uncommon in a normal Jianghu person, as long as his internal strength is still there, it can be resolved. However, Master found that this internal power could only be dissolved and disappeared, but could not be taken for himself, even if it was replaced with internal power that was both yin or yang. ”

Dugu Jing is like listening to a story, this kind of thing Grandpa may not understand, after all, there will be no sect that can gather all kinds of people like the Absolute Return Valley.

"Take it for yourself?" Dugu Jing asked word by word, is this kind of thought only people in the Demon Dao have it.

"Yes, it is completely impossible to draw conclusions from this matter after further investigation, Gongzi think about it, you and I have obviously practiced the same kind of internal strength, why can't you use the internal force outside my body, why are there no problems at all when I pass on the gong?"

"This ......" Dugu Jing was indeed stumped, but after thinking about it, this kind of question was not concluded, and it was impossible for him to figure it out for a while.

Later, the master modified this internal strength, although it failed to solve those problems, but it was able to be practiced by everyone, but it also produced some changes, which is why I said that if the son practiced this exercise, his original internal strength would not be used. ”

"What will change then?"

"After Childe practiced, all his own internal skills would be completely assimilated and transformed into yin. After that, unless Childe's family martial arts can transform the internal strength back into yang, he will no longer be able to practice the original internal strength. ”

"This ...... Isn't it just that the step of dispersal is omitted? And my family's internal strength is not so powerful, so naturally it can't be changed back......" Dugujing smiled bitterly.

"Because this is a set of basic internal skills, but there is no problem with the martial arts handed down by the childe's family, even if the martial arts that can be used only by relying on the internal skills of the family, they can be used normally. ”

"This, how else can this?"

"Also, as I said before, if someone injects true qi into someone else's body, it may affect the other person, and if the internal strength is damaged, it will not be able to dissolve. But after practicing this gong, there is no such trouble, and this gongfa gongzi can be understood as the transmission of gong, which can turn the true qi that others actively inject into the power of passing on the gong, and directly take it as his own. ”

"So you can't take the initiative to absorb other people's skills?" Dugujing asked softly.

"Of course not, it's not the kind of work that doesn't work. I didn't know much about it at the time, but Master said something that made me understand, and Master said, 'You can understand this exercise as the third type of non-attribute, which is compatible with other internal exercises.'" ”

"Oh, so I understand the difference. Dugujing also suddenly realized.

"In that case, then I'll go back to rest, whether Childe wants to practice this kung fu, please consider it yourself. ”

After saying that, Du Xi'er left with her head bowed, and Dugujing also nodded and watched her return to the house.

"By the way, Miss Qin, does this internal skill have a name?" Dugujing suddenly asked.

"Yes, but I forgot, Master doesn't care about that. ”

"Okay...... Okay. ”

Dugujing reluctantly sat down cross-legged at the door.

"Let's practice. ”

The step of not dispersing the gong made Dugujing more acceptable, and it was more actually what Du Xi'er said, and this internal skill would not affect his continued use of other martial arts inherited from the family.
