The candles in the cave wall are full of inlays, and Zong Zheng is sitting on the side of the bookshelf, carefully practicing the "Yin and Yang Sutra", and he can see it very well.

Xuanmen has three secret books known as the three treasures of Xuanmen, one of them "Yuan Ji Gong", this kung fu conceals the art of yin and yang, for the human element and practice, exquisite, is everyone's dream of kung fu cheats;

Zong Zheng was seriously injured and was in urgent need of Yuan Ji Gong to recuperate, so Xi Jie handed over the book to Zong Zheng and asked him to carefully consider the practice in order to recuperate his body as soon as possible.

Zong Zheng closed the book, stood up, and suddenly walked to the cave wall on the right, staring at the topographic map of the Pangu peaks carefully.

Xi Jie carried the bamboo basket and paced softly, came to the cave hall, and when she walked to the door, she saw that Zong Zheng was stunned by the topographic map on the right side of the cave wall, so she stepped forward and said, "What do you see from these pictures?"

Zong Zheng could see that he didn't notice Xi Jie, and couldn't help but be secretly shocked in his heart, and turned to Xi Jie and replied, "Didn't see anything?"

Xi Jie put down the basket and asked softly, "Have you finished reading the "Yin Yang Sutra" that you gave you yesterday?"

"Well, I've finished reading it, and the "Yin Yang Sutra" is really mysterious. Zong Zheng replied, his face full of praise for the "Yin Yang Sutra".

Xi Jie listened to Zong Zheng's tone, and estimated that Zong Zheng seemed to have finished reading, and was a little incredulous, so she asked, "Have you finished reading?"

"Well, just finished reading. Zong Zheng replied lightly,

"So, is there anything you don't understand?" Xijie continued to ask,

Zong Zheng looked at the "Yin Yang Sutra" in his hand, his eyes flickered, and he replied with some hesitation: "It should be, no." There seemed to be some unconfidence in his face.

Xi Jie didn't have anything to say about Zongzheng's wisdom, but if she could understand the content in such a short period of time, it would make Xi Jie a little hard to believe, Xi Jie wanted to test Zongzheng, so she said: "Okay, I'll test you." ”

Xi Jie pondered for a moment, and then chose a question that she thought was the most subtle in the Yin Yang Sutra and asked, "What is the taboo of 'Yin Yang Advance and Retreat'?"

Zong Zheng pondered for a moment, and then replied confidently: "Yang Jin is not to replenish Yang, Yin Jin is not to replenish Yin, blindly supplementing Yang will only make Yang Qi overflow, blindly supplementing Yin will only make Yin Qi stagnant, in the same way, Yang should not retreat and blindly remove Yang, Yin retreat and blindly remove Yin." This is called the taboo of yin and yang. ”

Xi Jie nodded slightly, and asked again: "What is the key method of 'Yin and Yang Advance and Retreat'?"

Zong Zheng immediately replied: "Yin advances and yang retreats and is supplemented by yang advances, and yang advances are supplemented by yin retreats, in the same way, yin retreats are supplemented by yang retreats, and yang retreats are supplemented by yin retreats. ”

After hearing this, Xi Jie thought to herself: "It seems that he has comprehended the subtleties of the Yin Yang Sutra, and he is really talented. ”

Zong Zheng suddenly felt a pain in his chest, his face frowned, and he couldn't help but hold his chest with his hand.

Xi Jie said worriedly: " Your lungs are injured by three kinds of internal forces, one is an extremely masculine internal force, one is an extremely cold internal force, and the other is the internal force of yin and yang, I never know the outside kung fu, so I don't know what kind of martial arts the masculine internal force and the internal force of the yin and yang come from, but the extremely cold internal force is from the master's Yuan Ji palm, depending on your good and bad situation at this time, I am afraid that in a few days, when these true qi converge to a certain extent, it will inevitably explode, and at that time, you will not die and will be in great pain. ”

Zong Zheng held his chest weakly and replied: "Senior sister, is there a way to save me?"

Xi Jie replied: "Cultivating Yuan Ji Gong can help you heal your internal injuries, but it also needs to be supplemented by Yin and Yang Qi to reconcile several True Qi in your body. ”

Zong Zheng read the "Yin Yang Sutra", and immediately knew what Xi Jie meant, so he muttered: "Senior sister means"

"Yes, exactly. Xi Jie looked at Zong Zheng, blinked slightly, and replied indifferently,

"However, I don't know the details yet, and I don't know how to do it. Although Zongzheng understood the theory, he was not sure about the actual operation of the Yin and Yang Qi conditioning, so he said honestly,

Xi Jie said: "At present, your injury cannot be delayed, and you need to be recuperated as soon as possible, I will give you the "Yin and Yang Sutra" to show you, just to let you know the general harmony of yin and yang." ”

Immediately, Xi Jie sat cross-legged on the ground, stretched out his palms and said, "Whatever I say, you can do." ”

Zong Zheng saw that Xi Jie was ready, so he also sat cross-legged on the ground, the two faced each other, Zong Zheng looked at Xi Jie, couldn't help but be a little restrained, and slowly stretched out his palm, and the two palms were palms to palms.

The moment the two of them touched each other's palms, they each had a strange feeling in their hearts, for Yu Zongzheng, this feeling reminded him of Xianjie, and for Yu Xijie, this was her first contact with a man, this feeling was strange and indescribable.

Zong Zheng's eyes looked at Xi Jie motionlessly, he had not seen Xi Jie up close before, but now he looked at it closely, Zong Zheng felt that the senior sister in front of him and Xian Jie were very similar, so he could see the gods.

Xi Jie saw that Zongzheng was looking at him in a daze, and he was a little evasive in his heart, so he closed his eyes and said, "When you are exercising, you need to concentrate on your thoughts, junior brother, close your eyes with me." ”

Zong Zheng saw that Xi Jie closed his eyes, and when he woke up for a while, Fang knew that Fang was a little rude, and he didn't have time to apologize, so he also closed his eyes.

"Later, you will only focus on Yang Jin, and I will first inject Yang Qi into your body, and then Yin Qi. Xijie said,

Zong Zheng said 'um', and then poured yang energy into his whole body, Xi Jie first injected a wave of masculine energy into Zong Zheng's body, Zong Zheng felt a trace of warmth in his chest, and then his heart began to stagnate, and beads of sweat began to appear on his face.

After a moment, Xi Jie imported another breath of yin and cold qi, and when the yin and cold qi slowly entered the body and permeated the whole body, Zong Zheng felt much more comfortable, not only did there be no stagnation of true qi in his chest, but the yang qi went further into one layer.

"Listen, let's take our internal strength together. Xijie said,

Immediately, Zong Zheng withdrew his palm to contain his true qi, and Xi Jie also withdrew his palm, returned to the two ribs, slowly opened his eyes and asked Zong Zhengdao: "How do you feel now?"

Zong Zheng replied happily and excitedly: "Oh, senior sister, I understand, Yang Jin can only go one level further by relying on Yin Jin, so that Yin and Yang can advance together." ”

Xi Jie nodded and said, "It is precisely this reason that the yin and yang qi in your body has been out of balance, and now only by constantly advancing yin and yang can you reconcile the inherent true qi in your body." ”

Zong Zheng couldn't help but sigh: "I didn't expect that 'Yin Yang Advance and Retreat' was so broad and profound, and it was completely different from what I thought. ”

Xi Jie got up and said: "Master had a lot of research on the two qi of yin and yang before his death, and he also had a very unique insight into the harmony of yin and yang. Xi Jie said and took a book from the bookshelf and said: "You can take a look at this "Yin and Yang Bagua Zhi Volume I" first, I hope you can be familiar with the structure of Pangu Cave after reading it, and you can freely enter and exit Pangu Cave in the future." ”

Zong Zheng immediately got up, took the book from Xi Jie's hand and said, "Well, thank you, senior sister." ”

"This is the first volume of Yuan Ji Gong, since you have finished reading the "Yin and Yang Sutra", you will practice Yuan Ji Gong well, according to my method today, take care of it, I will come back tomorrow, there is something to eat in this basket, and I will practice after eating!" Xi Jie said softly, with deep concern and consideration for Zong Zheng between her words, she only glanced at Zong Zheng and left.

Zong Zheng also felt the kindness of his senior sister, this is the best person he felt for himself except for his mother and Xianjie, she not only spared no effort to save her life, but also taught herself profound martial arts and knowledge without reservation like a master, Zong Zheng couldn't help but have a great sense of gratitude to Xi Jie in his heart.

Zong Zheng suddenly thought of the situation when he looked at Xi Jie, and couldn't help but deeply suspect that Xi Jie was Xian'er's lost sister in Pangu Peak, the faces of the two had great similarity, in terms of age, the two were almost the same, and Zong Zheng was more willing to believe that Xi Jie's appearance in Pangu Peak was by no means living here since childhood, therefore, Zong Zheng decided to wait for the next time Xi Jie came again, and asked him face to face, otherwise, this matter was pressed in his heart, and it was very uncomfortable.

When Xijie's footsteps were far away, Zong Zheng couldn't help but think of Xianjie again, he was very worried about Xianjie, Zong Zheng didn't know that Xianjie had successfully used two white eagles to fly away from the Beauty Valley, and got the antidote to suppress toxicity for three years, so in his heart, he was still carefully thinking about how the valley master would treat Xianjie.

After some calculation and analysis, Zong Zheng thinks that Xian'er has no worries about her life for the time being, but the valley lord will definitely use Xian'er to do something she is unwilling to do, Zong Zheng is very clear, the biggest possibility is to use Xian'er as an espionage tool to penetrate into the high-ranking officials of the Song Dynasty, according to Xian'er's personality, she will definitely not obey, just afraid that there will be a worry about her life, thinking of this, Zong Zheng was anxious, looking at a pile of books on the shelf, and then looking at the Pangu group of peaks on the right side of the cave wall, Zong Zheng suddenly felt helpless.

In fact, Zongzheng's assumptions are based on the fact that the valley lord conceals his own affairs from Xianjie, but as everyone knows, Xianjie already knows the news of Zongzheng's uncertain life and death, if Xianjie can't get out of the Beauty Valley smoothly, then she will already be ready to fight with the valley master, even if she dies in the Beauty Valley.

Xi Jie reluctantly returned to her cave room, sat on the edge of the bed, closed her eyes, her mind was full of the situation of face to face with Zong Zheng just now, palm to palm, thinking of this, she had a strange feeling in her heart, a feeling that she had never had before, but this feeling was unclear to herself, sweet but a little astringent, astringent and a little sour, and occasionally tasteless.

The whole cave was filled with a warm atmosphere, revealing half a point of sourness, accompanied by flickering red candles, embedded with Xijie's contemplative figure.
