Lin Tian nodded, staring at Mu Xue's beautiful and fair face, not knowing what to say for a while, looking like he wanted to say something.

He knew in his heart that Mu Xue's help to him was sincere, but he couldn't repay it directly.

Just as Mu Xue turned around with a smile, Lin Tiancai hurriedly shouted, "Mu Xue, wait a minute......"

"Huh?" Mu Xue turned around, her beautiful eyes blinked, and she smiled: "What's wrong?" ”

"Mu Xue, I'm ......" Lin Tian blushed rarely, and held back a few seconds before holding back a few words: "Thank you, I will repay you." ”

"Repay me?" Mu Xue was stunned for a moment, then walked in front of Lin Tian, felt that she was not close enough, and took another step forward, her face was almost on Lin Tian's face, Lin Tian was stunned, and subconsciously took two steps back, Mu Xue saw this and showed an angry face, pursed her lips and took two steps forward, grabbed Lin Tian, who was about to retreat, and said indignantly: "What, am I terrible?" ”

Lin Tian hurriedly shook his head, "No, no, I didn't mean that......"

Mu Xue: "Then why are you hiding?" ”

Lin Tian blushed and said, "I, I suddenly found that you are so fragrant, so I ...... I consciously stepped back. ”

"What kind of answer is that?" Mu Xue burst out laughing, her eyes were even more excited, and after a while, she thought about it and said, "If you want to repay me, you have to promise me three things." ”

Lin Tian was stunned, "Those three?" ”

A hint of cunning flashed in Mu Xue's eyes again, and said: "The first thing is to believe what I say, you can do whatever I say, of course, I won't let you do anything that makes you embarrassed." Second...... When I come back, you're going to teach me the lyrics of that ballad yourself. As for the third thing....... I haven't thought about it yet, so I owe it first. ”

Lin Tian nodded, these are trivial things, as for the third thing, how does it feel like a plot that will appear in a comic book?

Seeing Lin Tian nodding in agreement, Mu Xue smiled like a peach blossom, turned around happily and waved her hand, and left with Gan Cheng and Baker.

Baker has followed everyone without saying a word since he came to the Dragon Soul City, and when he saw Mu Xue's unusually intimate behavior towards Lin Tian, a trace of jealousy welled up in his heart, he looked back at Lin Tian deeply, and then turned his head and left with Mu Xue.

After everyone left, only Changkong, Treading Snow and himself were left, and after Lin Tian explained a few words to the two, he jumped on the stone and came to the big stone, which was the location of the corgi station before.

Lin Tian bowed respectfully and said, "Master." ”

Long Li nodded and motioned for Lin Tian to come up, and Lin Tian jumped onto the big stone.

"Sit down."

"Yes, Master."

After Lin Tian sat down cross-legged like Long Li, Long Li opened his eyes and said, "Xiao Tian, do you know what the Origin Qi is?" ”

Lin Tian nodded and said, "Changkong once told me that the Origin Qi is the innate Qi in the human body, the source of life. ”

Long Li nodded and then shook his head, saying: "It's just half right, the beginning qi is actually the qi of heaven and earth, the qi of all things, it can also be said that all things begin with qi." ”

Lin Tian was stunned when he heard this.

Long Li said: "A long time ago, we human beings have discovered the existence of the Origin Qi and used the Origin Qi to cultivate, do you know what the purpose of cultivating the Origin Qi was in the first place? ”

Lin Tian shook his head, he knew this, he was completely stunned.

Long Li smiled kindly: "It's to strengthen the body." ”

Lin Tian was stunned, and after a moment he was surprised: "It's so simple? ”

"So what do you think?" Long Li said: "According to ancient records, a long, long time ago, people at that time only discovered that cultivating the first qi had the effect of strengthening the body and prolonging life, and did not find that the first qi could also be used to fight, until later, human society flourished, the territory continued to expand, and they had to face other creatures who also lived in this world, so at that time, the ancestors gradually learned to use the first qi and weapons to fight. ”

After listening to this, Lin Tian suddenly realized.

Long Li continued: "The first qi is divided into yin and yang, but all we can use is yang qi, which can also be called yuan qi, and yin qi can not be used until much later, do you know why? ”

Lin Tian shook his head again, he had never heard of it.

Long Li said: "I'll take a look at your spiritual energy." ”

"Oh." Lin Tian raised his head, and black flames immediately poured out of his hands.

When Long Li saw Lin Tian's spiritual energy, a trace of surprise flashed in his eyes, and then he nodded and said, "It is worthy of fusing the yin qi born from the two major royal families, and it is really different." ”

"Yin Qi?" Lin Tian was stunned for a moment, but how could he not hear the meaning of Long Li's words, and said in surprise: "Master, you mean that spiritual energy is yin qi?" ”

Long Li nodded with a smile, with appreciation in his eyes, "Exactly." ”

This time it was Lin Tian's turn to be shocked, he never expected that the spiritual energy was actually yin qi, he really felt incredible.

Lin Tian was puzzled and said, "Master, doesn't the book say that psionic energy is the ability evolved by human beings and all living beings?" ”

Long Li smiled: "That's true. ”

Lin Tian was even more puzzled, "Then how do you say that spiritual energy is yin qi?" ”

Long Li explained: "Originally, Yin Qi was not obvious, but in the process of human evolution, it may be said that it is unintentional or inevitable factors that stimulate the embodiment of Yin Qi. ”

Lin Tian fell into deep thought when he heard this.

Long Li smiled, not in a hurry to speak, but waited for Lin Tian to think.

After a while, Lin Tian said, "Master, since Yin Qi can be concretized, why can't Yang Qi?" ”

Long Li shook his head, "It's not that you can't, but Yang Qi is different from Yin Qi, and you need more Yang Qi than Yin Qi, and that's the difference." ”

Long Li's eyes flashed, and he continued: "If you want to make Yang Qi also concretized, you must have a strong enough Yang Qi, now people don't know the two Qi of Yin and Yang, they only know the powerful power brought by Yin Qi, and ignore that Yang Qi is the authentic martial art, of course, a single Yang Qi cultivation to the extreme is also limited, and it is even more difficult to break through, only Yin and Yang practitioners can continue to become stronger." ”

Lin Tiandao: "Master, how should we practice yin and yang?" ”

Long Li got up with a slight smile, carried one hand on his back, and pointed the other to the yin and yang fish that was always slowly rotating in the middle of the waterfall, and said: "In ancient times, there was once a great kingdom, they claimed to be the descendants of the dragon, and the cultivation method of yin and yang qi came from there, and now only the yang qi cultivation method has been handed down, as for how to cultivate yin qi, you need to understand it." ”

"Satoru?" Lin Tian was a little confused.

"Yes, that's enlightenment." Long Li said: "The cultivation method of yin qi is hidden in the yin and yang fish, you need to come to comprehend, whether you can realize it or not depends on your ability." ”

"That'...... Master, have you realized? Lin Tian asked.

"I'm ashamed to say that I only know the skin." Long Li shook his head and said, "Yin and Yang contain the truth of the universe, and I have always been a mortal, and I can only peek into the mystery of the tip of the iceberg. ”
