Listening to Lin Wangshu's advice, Ning Wushu's mind also sank. She knew that what Lin Wangshu said was right, not only was it extremely difficult to find the fruit of sweet tea, but it was also an unimaginable thing to reach the cultivation realm that could save Lin Mobai in just two or three years.

Slowly, Lin Wangshu also talked to Ning Wushu about the Yin and Yang Qi Technique. This method of mind is a set of mental methods handed down from ancient times by the Lingjing Gate, the Yin and Yang Qi Recipe has never been seen before, and there is no one after it, it is the only one in the world that uses the two qi of life and death to achieve the wonderful effect of "exchanging life for life", although everyone knows that the cost of this replacement is not equal, and a peerless master to save an ordinary person, it also needs to pay a great price; But even so, no one has been able to improve it for thousands of years, and today's martial arts research is all about the internal power circulating in the meridians, rather than the mysterious qi of life and death, even if they have practiced the yin and yang qi technique and know how to use the two qi of life and death, they still can't know where they come from.

Therefore, if Ning Wushu wanted to save Lin Mobai after she took the fruit of sweet tea, so that Lin Mobai would not turn into a pool of blood, then Ning Wushu needed to make his skills reach an unimaginable realm. Even Lin Wangshu saved Ning Wushu back then, but he lost all his skills in a certain period of time, so if Ning Wushu wanted to save Lin Mobai's life, at least, she had to reach the realm of Lin Mobai back then.

"Actually, your talent is no worse than that of your sister. Lin Wangshu said to Ning Wushu: "Sister, like you, the meridians are much thicker than ordinary people, she has been practicing martial arts since she was four years old, and what she has learned is the orthodox internal strength of the Lingjing Gate. ”

"But what my sister is really powerful about is her understanding and innovation of martial arts. First, through the study of the sword technique, she actually created the shadowless sword technique on the basis of a set of mediocre swordsmanship, and even fused the shadowless sword technique with the heavenly creation skill, at that time she had no opponents in the rivers and lakes, even Shen Banxia, the old owner of the Xingchen Building at that time, and Li Xuefeng, the leader of the Fish and Dragon Alliance, were a line worse than her sister. You know, my sister at that time was only in her early twenties. ”

"Therefore, only by breaking through the realm of the four seas can you have the opportunity to improve your internal cultivation to a super-first-class level. With a deep enough foundation of internal skills, even if you are lacking in skills, it is enough to use the Yin and Yang Qi Technique to save my sister, and I will also help at that time. ”

Ning Wushu quietly listened to Lin Wangshu's words, nodded and said, "Uncle, when I traveled all the way, I also chewed the Heart Method of the Five Lakes and the Four Seas repeatedly, but there was a problem that I could never understand. Back then, Chu Fangyu, the ancestor of the Lingjing Sect, divided the realm of the four seas into the four realms of the South China Sea, the East China Sea, the Boundless Sea, and the Divine Sea, but in the Zangzong Pavilion's book of the Five Lakes and Four Seas, there was no detailed discussion, what is the difference between the realm of the four seas? And since Chu Fangyu's predecessors, no one in the world has been able to break through the realm of the four seas, why is this?"

After hearing this, Lin Wangshu smiled freely, looked at Ning Wushu with starry eyes, and asked rhetorically: "Why are you asking me this question? In this world, in terms of understanding of the five lakes and the four seas, I am afraid that neither I nor Senior Brother Yun are inferior to you, and your understanding of the five lakes and the four seas is not as good as that of another person. ”

"That's right!" Ning Wushu clapped his palms and suddenly realized.

"I didn't expect that Ah Jue was actually Senior Sister Fu's child, no wonder his talent was so powerful. Lin Wangshu smiled and nodded, "Since you have already thought of where to find the answer, go ahead." ”

Ning Wushu laughed happily: "Then uncle, I'll go." Thank you, after chatting with you for a while, Wushu's heart is much more relaxed. ”

Lin Wangshu also smiled gently: "People in the rivers and lakes must have backers. Since you have to do the most difficult thing in the world, it is inevitable that someone will help you. Those who have attained the Tao should be helped, and if there is a need for help, don't be embarrassed. ”

Ning Wushu nodded heavily, and after saluting and saying goodbye, he turned around and left.

Lin Wangshu looked at the back of Ning Wushu leaving, and after a while, he said lightly: "You don't have anything to see, why have you been hiding on the side and not coming out?"

As Lin Wangshu's words fell, he heard a dry laugh from the dense mountains on the side, and Yun Feiyu Shi Shiran walked out. As usual, he was dressed in a silk single robe, and the bitter cold of winter seemed to be unable to invade him at all. Yun Feiyu walked slowly to the stone table and sat down, and said, "Your uncle and nephew are affectionate and recounting the past, and I am an outsider to make a lot of fun." ”

Lin Wangshu smiled and shook his head: "I can't help it." ”

"That's it. Yun Feiyu pursed her lips and said, "I'm also afraid that I will be careless and tell her about Xuanyuan and Luan." ”

"Hmm. Lin Wangshu raised his head, looked at the sky, and closed his eyes: "The matter of Xuanyuan's predecessor is indeed easy to mess up the heart of the bookless. She has too many things to deal with now, so let's put this matter to the back. ”

Ning Wushu walked briskly among the mountain roads, his mind racing like electricity. The fruit of sweet tea and the fairy mountain of the square pot are must be found, but in comparison, it is more important to understand the four lakes and seas. For Ning Wushu, breaking through the realm of the four seas is the biggest obstacle at the moment. Fu Jue may know something about this matter, but now that Fu Jue is in the Fish Dragon Guard, if he goes to Jinling City to find him, I am afraid that he will cause a lot of trouble, so Ning Wushu decided to go to the place where Fu Jue learned from all over the world, that is, the cave where Chu Fangyu retreated thousands of years ago to create the five lakes and four seas.

Ning Wushu hadn't been there, but he roughly knew what direction it was. Previously, when she went to the small valley in the Stygian Water Peak every day, Xuanyuan and Luan had told her, and Fu Jue had also said that it was a small cave hidden on the edge of Wanshi Island that could be passed from underwater. Of course, it was winter now, and it was of course impossible for Ning Wushu to dive to find the secret passage, so Ning Wushu decided to look for it from the small valley he was familiar with.

Moreover, I haven't been back for a long time.

Although he has been away for a few months, the road to the "small valley" is still familiar to Ning Wushu. After all, for the past five years, it has been a secret place for her, and whenever she has doubts, confusion, or something she wants to talk about, she will go there.

Although it was said that Xuanyuan and Luan didn't have to go to Ning Wushu back then, for Ning Wushu, she would still go if she didn't set foot in the wooden house and the small valley again.

The mountains are different from the ice and snow outside, isolated from the wind and snow outside, and the temperature is very warm. Ning Wushu came to the familiar small valley, and saw that everything was still the same as in the old days, and smiled happily.

Ning Wushu walked along the familiar path to the wooden house, the incense she lit in front of the wooden house when she left the Lingjing Gate a few months ago had already been burned, only a few ashes remained, and the Yan soldiers made by Xuanyuan and Luan were still in place, Ning Wushu gently stroked the back of a Yan soldier when he passed by, and the Yan soldier lowered his head and did not move.

"Sister Xuanyuan, no book is back. ”

Ning Wushu knelt down in front of the cabin and solemnly kowtowed three times.

"But I'm going to be leaving again soon. Ning Wushu stood up and said softly. She looked at the cabin, as if she saw Xuanyuan and Luan standing in front of her, smiling at herself. Xuanyuan and Luan have only been with her for a few months, and now they have been gone for five years, but for Ning Wushu, when her family was in exile and unaccompanied when she was thirteen years old, it was Xuanyuan and Luan who gave her a real sense of home, so in her heart, Xuanyuan and Luan did not leave.

"Sister, I have a lot of things I want to say to you, but Wushu is afraid that I won't be able to hold back what I say, so it will delay things. Last time, I went to save my father, and this time, I want to save my mother. Sister Xuanyuan, I hope you will bless me. ”

The space in the small valley is not big, but it is not small either, although Ning Wushu knows the general location of Chu Fangyu's retreat, it is not easy to find. Fortunately, Ning Wushu's organ technique was inherited from Xuanyuan and Luan, and he couldn't understand the style of this Xuanyuan sister, or Ning Wushu's idea of setting up the mechanism was the same as Xuanyuan and Luan. So soon, Ning Wushu found a clue to the cave.

It was a pond, and the water in the pond flowed out of the mountain wall, which was the mountain spring water, and there was a small drainage outlet at the bottom of the pool, and the mountain spring water did not know where it flowed. There are also a few small fish in the pond that swim around with their tails swinging, when Ning Wushu first came here, he was suspicious of these small fish, thinking to himself in this closed mountain, how could there be small fish that have survived? What do they eat?

At that time, Ning Wushu asked suspiciously, but now when she walked to the edge of the pool, she looked down at the small fish, but she found it at a glance, this was not a real fish, but a ...... A fish made by tricks. She stretched out her hand to fish out a small fish from the pool, only to feel that it was very light, sure enough, it was a fish made of special wood, when the fish left the water, the tail no longer wagged, it turned out that this small fish was driven by the force of the mountain spring water to drive its tail, so as to swim slowly.

Ning Wushu knew that Xuanyuan and Luan would not put such a few well-crafted small fish in the pool for no reason, and when she taught herself, she had said that there should be no superfluous strokes in the arrangement of the mechanism, because the more and more complicated it is, the easier it is to make mistakes. But in the same way, when you set up a mechanism, you have to take it by surprise, even if you put your own mechanism under the noses of others, others may not be able to see that it is a mechanism.

Therefore, Ning Wushu believed that Xuanyuan and Luan put these small fish in this pond, not just for the sake of looking good. She stretched out her hand, fished out the small fish in the pond one by one, and placed them on the ground. After losing their current drive, the small fish stopped their movements and lay quietly on the dirt grass.

The location of this pool is exactly the direction of Chu Fangyu's retreat as described by Xuanyuan and Luan, so what is the purpose of building a pool here, and putting so many small trap fish in it? Ning Wushu smiled lightly, in the face of these trap fish, she had a feeling when Xuanyuan and Luan were taking the school entrance examination for her, so she rubbed her hands and picked up a trap fish, and her hand speed was as fast as electricity, dismantling the trap fish.

Sure enough, one of the trap fish was different in its body, not just a simple trap gear, but a small stone key hidden. Ning Wushu showed a smile and said in his heart, Sister Xuanyuan is really very attentive to Chu Fangyu's predecessors, and the retreat cave of the predecessors back then was worth Xuanyuan and Luan's attention.

With this stone key, Ning Wushu quickly found a small hole in the mountain wall on the side that matched the shape of the key according to the shape of the key, she inserted the key into the hole and twisted it slightly.

There was a quiet thud, and I saw that the mountain wall where Ning Wushu had inserted the key slowly cracked, and then turned into a stone door and opened on its own. Ning Wushu reached out to touch the edge of the stone door, only to see that the edge was extremely smooth, like a mirror, before the mechanism was opened, the joint of the stone door could be described as tightly fitted, without a trace, even Ning Wushu's vision could not find the clue, it can be seen that as early as a thousand years ago, the craftsmanship of the workers has reached the realm of supernatural realm.

Looking in from the stone gate, because there was no light, he could only vaguely see a stone staircase going down, and Ning Wushu's ears moved slightly, and he heard the sound of gurgling water from the end of the stairs.

"Sure enough, as Ah Jue said, the path to the cave can be found from the mirror lake. Ning Wushu casually made a torch and lit it, holding the torch and walking down the stone steps. The stone steps are not long, and the cave is not a secret room, but it is just a place where Chu Fangyu's dantian was destroyed and his internal strength was lost to create the law of the five lakes and the four seas, and Xuanyuan and Luan in order to commemorate Chu Fangyu's Nirvana rebirth for a period of time, only connected the huge mausoleum of "Little Valley" with the cave, which can be regarded as a trace of Chu Fangyu's existence in this world.

At the end of the stone steps, there is indeed a closed cave. There are obvious traces of human life here, and in the corners of the cave there are very simple stone beds and stone tables, and nothing else. What really fills the whole cave are the dazzling patterns painted on the walls, on the floor, on the bed table.

Ning Wushu was stunned and raised the torch, looked up, and saw that even the top of the cave was full of patterns, and Ning Wushu slowly walked forward while looking around at these patterns. These patterns are all kinds of villains, each villain has pointed out the acupuncture points and meridian routes in various directions, it is conceivable that the millennium Fang Chu Fang Yu is in such an extremely simple environment, by constantly drawing one such villain after another on the stone wall, step by step to deduce the heart of the five lakes and four seas that no one has ever come before, completed a nirvana out of the cocoon, and returned to the peak of martial arts again.

And now, Ning Wushu is also looking for a way to break through the realm of the four seas in these countless patterns.
