The Yin Yang Heavenly Pool seemed to be infinitely deep, and Lin Yan had been diving for more than an hour, and he hadn't even seen his brother yet. The Yin Yang Heavenly Pool doesn't look very big, but its depth is tens of thousands of meters, and if you want to obtain innate qi, you have to dive to a depth of at least seven thousand meters.

However, the water of this Yin-Yang Heavenly Pool is full of yin and yang energy, and the deeper you dive, the richer the yin and yang energy contained. Of course, the greater the resistance, tens or even hundreds of times that of ordinary areas.

Under such a strong water pressure, it was impossible for even Lin Yan to dive to a depth below seven thousand meters in a short period of time. It took two hours, Lin Yan still only dived to a depth of about six thousand meters, and if he wanted to continue down, even Lin Yan had already felt a huge pressure, and it was not easy to complete.

Fortunately, Lin Yan's "Flood Desolation Holy Body" broke through the second layer, and his physical strength more than doubled, allowing him to continue diving at a depth of six thousand meters. In this way, another hour passed, and Lin Yan finally reached a depth of seven thousand meters. In just seven thousand meters, it took Lin Yan three hours, which shows how strong the resistance of this Yin Yang Heavenly Pool is.

Yin and Yang Tianchi contains the wonder of Yin and Yang, the opportunity of creation. It is roughly divided into three layers, the first layer is the place of yin and yang biochemistry, which contains the infinite mystery of yin and yang life and transformation. The pool water in this layer has the supreme power of yin and yang biochemistry, washing tendons and marrow, and rebirth, which is roughly more than 7,000 meters in range. And this area below 7,000 meters is the second layer of the place where yin and yang return. The interaction between the two qi of yin and yang undergoes a change of "return", returning to the basics, reversing the innate qi, and producing the innate qi with supreme use, which is Lin Yan's goal. Innate Qi is indispensable for body refining cultivators to break through the innate realm, and Lin Yan is determined to obtain it.

As for the third layer, Lin Yan didn't know very well, he only knew that it was called the Yin Yang Jedi, according to Ta Ling, this was the final place of creation of the Yin Yang Heavenly Pool, with incredible magical power.

finally came to a depth of seven thousand meters, but Lin Yan had not seen a wisp of innate qi yet, and the innate qi in the seven-meter area was pitiful, so Lin Yan decided to continue diving.

Innate qi is also divided into grades, black and white is secondary, gray is preferred, and purple qi is respected, using different innate qi, the strength after breaking through the innate is not the same. The black and white innate qi cannot be regarded as a complete innate qi, it can only be regarded as a semi-finished product, although it can also make people break through, but after the breakthrough, the strength is the weakest. The gray innate qi is considered to be the superior innate qi, and if you use the gray innate qi to break through the innate qi, the strength will change drastically.

The last is the innate purple gas, the innate qi is the innate qi after endless years of precipitation, the innate qi, the purple is respected, the innate purple gas, the creation of the congenital. This word creation is not just talking, the innate purple qi creation and transformation Xuangong has incredible mysterious power.

Yin and Yang are in harmony, all things are wonderful, and the innate qi contains the opportunity of yin and yang creation, which can not only enable body refining monks to break through the innate nature, but also be the supreme divine object of enlightenment and cultivation.

Lin Yan had already dived to a depth of seven thousand five hundred meters at this moment, and across Lin Yan was a huge innate qi, black and white, flowing and changing with each other, which seemed to contain some kind of strange mystery of rules. Lin Yan stared at the change in the innate qi in front of him, and his head suddenly roared, as if some kind of restriction had been broken.

Lin Yan only felt as if he had entered a strange state, and that feeling was like an epiphany. Yes, epiphany! Just like Lin Yan's feeling of epiphany in the central temple is exactly the same, the fire ability in Lin Yan's body and the spiritual ability in his mind are all undergoing unexpected changes in Lin Yan.

Everything in the world is divided into two sides, yin and yang, yin and yang are combined to generate all things, each thing is a small Taiji, and everything in the world constitutes a larger Taiji, but whether it is a small Taiji or a large Taiji, it is a complete Taiji. Taiji divides and gives birth to yin and yang, and yin and yang are combined to give birth to all things. Therefore, all things have yin and yang, and there are two sides, and only a stability like Tai Chi can make all things exist for a long time without dissipating.

Fire is also divided into yin and yang fire, but only after understanding the mystery of the harmony of yin and yang can we know this. Originally, Lin Yan's current realm was not enough to comprehend the mystery of yin and yang, but through the anti-heaven effect of the yin and yang heavenly pool, Lin Yan was able to understand the secret of yin and yang.

The flames in Lin Yan's body had completely turned blue at this moment, and then the blue flames actually swirled, forming a Tai Chi appearance, and slowly divided into two flames. After a while, they were combined again and turned into a giant Tai Chi pattern. However, after a while, the Tai Chi pattern collapsed again, and it could only be repeated like this, and could not exist for a long time.

The two poles of fire are yin and yang, the yin is the yin fire of Ding, the yang is the yang fire of C, the way of yin fire is the way of soft fire, including infinite prosperity, the mystery of creation, and the way of yang fire is the way of rigid fire, including the mystery of supreme destruction, masculinity, and vastness.

The combination of yin and yang fire is the real way of fire, Lin Yan has realized this, and he is already a beginner in the path of fire.

Lin Yan's mind is also undergoing tremendous changes at this moment, and the changes in the yin and yang qi in front of him are constantly evolving in his mind, making it up over and over again, just evolving and changing. Slowly, Lin Yan closed his eyes and floated quietly in place.

I don't know how long it has been, Lin Yan has been stopping somewhere, neither floating nor sinking. I saw that the water around Lin Yan actually surrounded his body and began to rotate slowly, forming a Tai Chi pattern. Lin Yan sat peacefully in the center of Tai Chi, motionless, as if he was having an epiphany.

As time passed, the Tai Chi pattern around Lin Yan became larger and larger, and since it radiated to the size of a radius of several hundred meters.

Fortunately, Lin Yan is now in a deep water area thousands of meters below, otherwise, it would be difficult for others to make such a big disturbance. But even so, the surface of the Yin-Yang Heavenly Pond was still subtly affected, and a huge Taiji-shaped ripple floated silently on the surface of the Heavenly Pond.

However, no one saw this scene, because now all the people were still cultivating, and no one had discovered this vision, and no one had found that Lin Yan had disappeared.

After the Tai Chi pattern rose to the extreme, it could no longer continue to expand, and then it began to shrink slowly, and finally the Tai Chi pattern a few hundred meters in size actually shrank to only about one meter in size, floating quietly around Lin Yan's body.

"Boom!" Suddenly a loud noise came, and I saw that the Tai Chi pattern around Lin Yan's body instantly collapsed, turning into black and white yin and yang qi. Then, the two yin and yang qi intersected and entwined with each other, and finally turned into wisps of gray innate qi.

This is the so-called Tai Chi birth, transformation, and return, the so-called Tai Chi is divided into yin and yang, and yin and yang are combined and reborn all things. All things are Tai Chi, and Tai Chi contains all things. The two qi of yin and yang are really the infinite perfection of creation, containing the supreme mystery of all things. Yin and yang give birth to each other, evolve all things, and all things return to yin and yang. The supreme meaning of the transformation of yin and yang is nothing more than the three of life, transformation and return, but it contains the infinite mystery between all things, and Lin Yan is just able to get a glimpse of its heroic branches.

The Yin and Yang innate qi around Lin Yan's body began to slowly dissipate, until it completely dissipated, when Lin Yan suddenly opened his eyes. I saw a strange light emanating from his eyes, and there seemed to be two qi circles of yin and yang in it.

In Lin Yan's sea of knowledge, a gray seed began to sprout, giving birth to a small branch, but there was not a single leaf, just a small shoot. The main trunk is black and white, with a faint gray mist rising, and a small spor grows on the main trunk, which seems to bloom a tender green leaf at any moment.

Lin Yan looked at the sprouts of small trees in his sea of knowledge, and a faint smile appeared on the corner of his mouth. This small sapling is the sprout of the mystery that Zhu Rong mentioned before, which can only be comprehended by innate martial artists. However, Lin Yan comprehended the mystery of martial arts by chance, with the help of the supreme power of Yin Yang Tianchi, and it was also the mystery of Yin and Yang.

You must know that among all the martial arts mysteries, the yin and yang mysteries are the top martial arts mysteries, and they are the martial arts mysteries that directly point to the origin of heaven and earth. However, Lin Yan has only comprehended a small part of the meaning of yin and yang now, and almost all of them are about the mystery of yin and yang of fire. If you want to comprehend the complete meaning of yin and yang, it is still too far away for Lin Yan now.

After all, people who can comprehend the mysteries of martial arts in the realm of the day after tomorrow are all geniuses of the anti-heaven level. Moreover, Lin Yan comprehended the mystery of yin and yang, even if Lin Yan used the help of yin and yang Tianchi, it was already incredible.

Lin Yan was able to comprehend the mystery of yin and yang in the realm of the day after tomorrow, even Ta Ling felt very incredible, as the tower spirit of the Demon Suppression Tower, she didn't know how many geniuses she had seen for endless years, but there were few who could reach Lin Yan's point, even when the Nine Phoenix Witch Clan was at its strongest, there were not many such geniuses.

At this moment, the flames in Lin Yan's body had been completely divided into two streams, one towards the fire and the other towards the fire

The fire transforms, intersects with each other, and slowly becomes a faint Tai Chi pattern. This time, the Tai Chi pattern did not collapse, and with the fact that this Tai Chi pattern became clearer and clearer, the tree of mystery in the sea of Lin Yan Zhi sprouted and grew a little taller. The spores on it became a little larger again.
