Ning Wushu has now practiced the five lakes and four seas to the realm of Xiaocheng, and he naturally has an understanding of the five lakes and four seas mental method. Therefore, when she preliminarily browsed the patterns covering the entire cave, she had basically understood a derivation process of Chu Fangyu.

For example, those villains depicted on the top of the cave are actually no different from the five lakes and seas that Ning Wushu is practicing now, they are basically finished products, and they are at the end of the deduction process, while those villains depicted on the stone bed and stone table are much more complicated, and those patterns show all kinds of speculations that Chu Fangyu has had in the process of creating the five lakes and four seas, some of which are wild imaginations. Some of them follow the rules, and from these deduction processes, we can also get a glimpse of what a genius Chu Fangyu was back then.

Ning Wushu took a deep breath, found a place to fix the torch, and began to study the patterns.

The so-called understanding is naturally to know what it is and why it is true. Now placed in the Tibetan Pavilion of the Five Lakes and Four Seas Heart Method, is summarized by later generations, just follow the map. But if you know Chu Fangyu's process of deducing the heart of the five lakes and four seas, you must be able to know what kind of realm the four seas realm is.

And the reason why Ning Wushu has no way to learn about the Four Seas Realm from the current collection of books is also because since Chu Fangyu, no one has practiced the Four Seas Realm. Therefore, the book only has the way of breathing and breathing, and the circulation of meridians, but does not elaborate on the specific reasons for the division of the four seas and ...... How to break through the realm of the four seas.

Yes, in the current collection of the Spirit Mirror Gate, there is no description of how to break through the realm of the four seas at all.

Ning Wushu had doubts about this in his heart, and he also discussed it with Yun Feiyu. But Yun Feiyu's answer was only vague, and the sentence "no one knows" was brought over. Now, only in the most primitive traces left by Chu Fangyu, this answer is being found.

Because she was afraid of missing something important, Ning Wushu looked very carefully, and did not let go of the slightest detail, she stretched out a finger and stroked the little people carved on the stone, thinking seriously about Chu Fangyu's intentions and thoughts when he drew this stroke.

There were thousands of villains in the cave, and before he knew it, Ning Wushu had been in the cave for two days and three nights. At first, she went out to find something to eat because she was hungry, but as she studied these villain patterns more and more, she gradually fell into obsession and gradually forgot to sleep and eat.

Fortunately, Ning Wushu's internal strength is now deep enough, and his physical fitness has already far surpassed ordinary people, otherwise he would have collapsed long ago without eating, drinking, or sleeping for two days and three nights.

But even so, the current Ning Wushu also had a yellow complexion, two dark circles under her eyes, and the knotted hairstyle that was originally delicately coiled on her head had already been scattered, and she was standing on the stone table at this time, stretching her neck and tilting her head, staring at the villain at the top of the cave.

"It shouldn't be...... It shouldn't be......"

Ning Wushu muttered to herself, her brows tightly locked, and she stretched out her hand and swiped over several small figures at the top of the cave.

"The realm of the five lakes, every time you advance a layer, you will open the four Qi meridians and eight veins, to the realm of Xiaocheng, the three yin meridians of the hands and feet, the three yang meridians of the hands and feet, the superintendent, the Ren, the Chong, the belt, the yin stilts, the yang stilts, the yin dimension, the yang dimension, the eight veins of the strange meridians are fully opened, so that a huge internal strength can be born in a moment, and the eight veins of the breathing and breathing are all rivers and lakes. But...... Why are the meridians on these little people depicting the realm of the four seas decreasing?"

"The internal force does not pass through the dantian, but the sea of qi, and the eight veins of the Qi meridian are all available, where does the internal force come from?

The more Ning Wushu looked at it, the more puzzled she became, the previous pattern had been studied by her in the past two days and three nights, with her experience in cultivating all over the world, it was not difficult to understand what Chu Fangyu had left behind, and it also deepened her understanding of this strange set of mental methods on her body. But when her research came to the realm of the four seas, she still ran into trouble.

The patterns left by Chu Fangyu are more difficult to understand the later they go, especially the depiction of the realm of the four seas, which is simply beyond the understanding of ordinary people. The originally complex pattern has become simpler here, but because of its simplicity, it is even more difficult to deeply understand Chu Fangyu's thoughts at that time.

After Ning Wushu thought for a while, he jumped off the stone table and ran his mind in the way depicted in the pattern, not only did she not feel any more powerful taste, but because she lost a few major meridians, her operation was even more blocked and sluggish.

Helpless, Ning Wushu shook his head, jumped back onto the stone table, and continued to study.

In fact, from the patterns left by Chu Fangyu, it can be seen that when he painted here, his thinking was already very clear, and he had clearly drawn the realm of "Four Seas". From the South China Sea to the East China Sea, and then to the Boundless Sea and the Divine Sea, at each level of the realm, there are fewer meridians on the villain's body. In the realm of the South China Sea, the Hand Taiyin Lung Sutra, the Hand Yin Pericardial Sutra, the Hand Shaoyin Heart Sutra, the Yang Dimension Meridian, and the Yang Dimension Pulse and the Yang Seesaw Pulse are all gone; in the East China Sea Realm, the Hand Yang Ming Large Intestine Meridian, the Hand Shaoyang Sanjiao Sutra, the Hand Sun Small Intestine Meridian, and the Yin Stilt and Yin Dimensional Veins are all gone; and the Boundless Sea Realm is even more exaggerated, except for the Ren Du Second Vein, there is nothing left.

On the last pattern depicting the realm of the Shenhai Sea, the villain's body is empty, there is nothing, not even a single acupuncture point can not be seen, the villain seems to be just a shell, it just spreads its hands and feet like that, it can't be simpler, if you don't look carefully, you can't even see that there is a villain here.

Staring at the empty villain, Ning Wushu's heart suddenly skipped a beat.

"After entering the realm of the four seas, there is no distinction between entering and exiting, the sea is inclusive, and heaven and man are one......" Ning Wushu subconsciously remembered that when she read the five lakes and seas at the beginning of the year, the description of the realm of the four seas in the book seemed to explode in her mind, as long as she stretched out her hand to touch the light, she could understand the mystery of the realm of the four seas, but ...... She hesitated.

"All over the world, is it really such a frenzied mental method?" Ning Wushu was dumbfounded, not daring to believe his guess at all. But once that idea appeared, it took root in her mind, and she couldn't shake it off, and it got deeper and deeper, so that she couldn't question it.

Ning Wushu shifted his gaze back to the villain who depicted the realm of the South China Sea. She sighed and said to herself: "The realm of the four seas is not broken or established. When Chu Fangyu's predecessor dantian was destroyed, he came up with a way to replace the internal force of the dantian with the meridians around his body. However, after reaching the realm of the Five Lakes, this power is still imprisoned by the human body, and it cannot reach the point of infinity, so it ...... Chu Fangyu's predecessors came up with ...... When all the meridians cease to exist, the human body is like an empty shell, borrowing from heaven and earth and returning to heaven and earth. The four seas are boundless, is this the realm of the four seas?"

Ning Wushu made countless deductions and speculations in his heart, but only this last one was the most consistent with the pattern left by Chu Fangyu, and it could also explain why no one had been able to practice to this realm of the four seas from ancient times to the present. The meridians are the foundation of people who practice martial arts, and they are also connected with the internal organs and communicate with the internal and external things, as the so-called "the twelve meridians of the husband belong to the internal organs, and the external meridians are in the limbs", and the so-called "meridians, so the blood and qi camp yin and yang, the muscles and bones, and the joints are also", without the meridians, not to mention the inability to operate the internal force, I am afraid it is impossible to even live!

How could anyone survive after destroying all their meridians? Ning Wushu couldn't help but think that the old man who lived to the gray hair thousands of years ago not only did he not have the dantian qi sea in his body, but he didn't even have a little meridian left, so he couldn't help but shudder.

After figuring out the mysteries of the Four Seas Realm, Ning Wushu not only did not feel relaxed, but felt that a bigger stone was pressed on his heart. In order to break through the realm of the four seas and destroy his own meridians? This is no longer a dangerous act, but almost a suicidal act, when Chu Fangyu was in the state of the destruction of the dantian and the loss of internal strength, no one can know if this is a replicable method. Maybe Ning Wushu did this, and the result was a way to die.

But what if you don't break through the realm of the four seas? With the internal strength of your current Xiaocheng realm, even with the assistance of the True Immortal Dao Book, I am afraid that it will be impossible to save your mother and relatives at that time. So...... No longer cultivating the five lakes and four seas, but re-cultivating a martial art? The five lakes and the four seas will not entrench in the dantian, they can start again, with the help of the True Immortal Dao Book and the spiritual mirror gate for thousands of years, Ning Wushu believes that he is fully capable of practicing a martial art to the extreme, even if it is not impossible to reach the realm of Lin Wangshu......

But there is not so much time left. In two or three years, no matter how talented Ning Wushu is, once she has no talent from all over the world and starts from scratch, she has to lay a new foundation, and if she wants to achieve something, she must not only have talent and opportunities, but more importantly, the precipitation of accumulation over time. This is also why most of the masters of internal strength in the world are old people, and their physical functions are not as good as before, but in terms of internal cultivation, they definitely surpass most people in the world, because of the accumulation of days and nights, they have precipitated a huge amount of cultivation, which is a road that cannot take shortcuts.

Ning Wushu, who was already exhausted to the extreme, faced a bigger problem after finding the "answer". A feeling of emptiness and powerlessness swept over her, and she took a deep breath, took two steps, and lay down on the stone bed in the cave, tilted her head, and fell asleep.

In his dream, Ning Wushu saw many bizarre scenes.

She was surrounded by a number of people she didn't even know, all of whom had different faces, and were all expressionless and indifferent to the extreme. They held knives in their hands and approached Ning Wushu step by step, Ning Wushu wanted to rush out, but the strange thing was that she couldn't move at all, and in the next moment, countless knives had stabbed into her body, those knives were spinning and tearing, and the bright red blood bloomed like fireworks, but Ning Wushu didn't feel the slightest pain.

An unfamiliar face was very close, the indifferent expression on his face became hideous, and a hoarse sneer came out of his mouth: "Without the meridians, can you still kill people!"

Ning Wushu stared at this face, and suddenly felt a little familiar, and then remembered that this person seemed to be Liu Yuanliang, who had a relationship with him in the Raptors Village, when he received a palm from himself, and then he didn't know what happened. At this moment, Ning Wushu was startled, looked around, and saw that those people who were slashing around her with knives gradually became familiar, and they were actually those people she had personally killed or died because of her in the past period of time, including stubborn fish and dragon guards, nameless bandits, and some people she didn't recognize but seemed to be able to call their identities, these people were all powerful ghosts who crawled out of the underworld and came to ask for their lives.

Ning Wushu had a huge fear in her heart, but she couldn't move her hands and feet, she could only watch as these knives gradually chopped her into pieces, and her soul seemed to be out of the broken body, floated up, and slowly rose into the air, Ning Wushu lowered his head, and saw that the group of demons was like a group of monsters, after tearing Ning Wushu's flesh apart, they roared and roared and killed each other, and the thick blood surged wildly like a fountain.

Ning Wushu didn't want to look at this scene anymore, she raised her head and looked into the sky.

In the sky, there is a huge whirlpool, and it is not the sky, but the ocean. Ning Wushu's soul floated towards the huge ocean whirlpool hanging upside down in the sky, or was sucked in, she didn't know what it meant, she only felt an inexplicable yearning and expectation in her heart.

Suddenly, from the whirlpool came a huge and indescribable thing, this thing is bigger than the largest mountain in the world, with the power of pressing the heavens and the earth, Ning Wushu looked at it from a distance, but found that this existence covering the sky and the earth was actually the claws of an animal, but because it was too large, it was difficult to see the whole picture.

"What are these claws?"

As soon as Ning Wushu had this thought in his heart, the claw flicked suddenly, this time, forcibly separated the whirlpool in the sky from the ocean, revealing the endless depth behind the whirlpool, and in that depth, Ning Wushu could see four fiery red light clusters like the sun, she didn't know what they were, but in the face of these four light clusters, she could feel a strange warm feeling.

Suddenly, the four light clusters shook, and then they got bigger and bigger, Ning Wushu was suddenly engulfed by the dazzling light, and before she could have any emotions in her heart, everything disappeared.

Ning Wushu sat up in a cold sweat, she stretched out her hand to support the stone wall on the side, the torch hanging on the wall not far away had been extinguished, and the cave was dark, only the sound of water came from time to time in the pool in the corner of the cave that connected to the mirror lake outside. Ning Wushu gasped for breath, only to feel a sharp pain in her head, she didn't know how long she had been asleep, after being swallowed by the light of the four light clusters, she dreamed of a lot of things that she didn't know, but it seemed to mean something. I don't know if it's because studying all over the world has messed up her brain, or if it's some kind of foreshadowing.
