In the middle of the cave, he sat cross-legged facing the stone wall on the left, with the fallen leaves scattered on the ground, which had rotted and deteriorated early. The light shone in through the opening, right on the stone wall on the left, and he chose to sit down facing to the left, because it was because of that light, facing the light, it was better to face the darkness than to face the darkness that made him feel steady.

He took a few deep breaths of the lightly scented air, and was about to close his eyes to heal, but inadvertently found that there seemed to be countless small characters carved on the opposite stone wall. When he got closer, he saw that not only the stone wall on the left, but also the entire cave stone wall was carved with words, but after a long time, most of the words had been covered by dust, and if it weren't for the light projected on the stone wall, he might not have found it.

He gently patted away the old dust covering the stone wall, and the first thing that caught his eye was the four big characters of the dragon flying and the phoenix dancing: "The Secret of No Cliff".

Just looking at these four characters, vigorous and powerful, you can know that the carver has amazing arm strength, and writes good calligraphy. In just four words, he knew that the content of the words carved all over the stone wall must be some kind of secret to the cultivation of the Tao.

Ling Xuan couldn't help but get excited, because of what he had encountered since he was a child, he naturally didn't believe in pies falling from the sky, and he never had the luxury of expecting that he would encounter such a good thing one day, but at this time, he met him by mistake, which can be described as a blessing in disguise, and God favored him.

With a grateful heart, he continued to pat away the dust covering the stone wall, and with his movements, the mystery of "The Secret of No Cliff" was also quietly lifted.

"Contemptible people have no cliffs, and they have devoted their lives to the way of alchemy, which has taken hundreds of years, tasted all the herbs, and finally achieved a small success. Today, perceiving the destiny of heaven, knowing that it will comply with the will of heaven in the near future, whether it will succeed or not, is not yet known, so he left a lifetime of alchemy experience, contemptible and humble opinion, only for the reference of those who are destined. ”

"But where alchemy is pharmaceutical, the only thing is three, one is the material, the second is the law, and the third is the fire. Those who make materials may be able to do all things in heaven and earth, those who are lawful, the laws of alchemy, and those who are fire turn into pills, and their fate is unpredictable. ”

"The breadth of the material, no one knows the whole ......"

Reading those lines of graceful and rich small characters, Ling Xuan couldn't help but devote himself to it. The so-called "Secret of No Cliff" does not only refer to a certain method of alchemy, but explains how to extract the maximum medicinal ingredients from a natural medicinal herb from various aspects, how to maximize the limited medicinal ingredients extracted into an elixir, and how to make a pill exert its maximum effect. It elaborates on the supreme realm of alchemy from the three aspects of material, law, and fire, and although it is only empirical, it is all-encompassing and rich, fully embodying Wuyazi's profound knowledge and unique insights into the 'alchemy'.

After reading the words carved all over the stone wall, Ling Xuan seemed to be taught in person, listening to the words of the king, better than reading ten years of books, the feeling of sudden enlightenment made him sigh deeply, all kinds of problems that were only a vague concept in his mind before were easily solved, and his understanding of the matter of 'alchemy' was a thousand miles a day, as if he had suddenly reached a supreme realm.

The Secret of No Cliff does not record any specific alchemy exercises, but it is much more sophisticated than any alchemy exercises. The Erji Sect is famous for its alchemy, although Ling Xuan has not been in the Erji Sect for a long time, but he also knows its unpassed alchemy exercises, compared with the "Secret of No Cliff", there is a sense of clumsiness.

The secret method of alchemy of the Erji Sect is called "Shengtian Jue", and it has reached a realm that no one can reach, and it is a top-secret method that surpasses any alchemy practice under Fang today, but it only teaches people how to refine the high-grade elixir, not as comprehensive as "The Secret of No Cliff".

Ling Xuan couldn't help but have an idea that made his blood boil, if he combined the peerless 'method' of the "Victory Heavenly Formula" with the "Cliffless Secret", what kind of elixir would be refined?

Just thinking about it, he was eager to try, but at this time, he lacked equipment and was injured, so he had to force this tempting idea down, and when the time was right, he tried again.

He read "The Secret of No Cliff" several times, and after more than ten times, he kept every word in the secret in his heart, and the Tao was like a stream, but the rich connotation and profound insights in the secret did not diminish because of this, but the more he read, the more he felt that it was unfathomable, like an inexhaustible treasure mountain, and every time he read it, he felt that some hazy questions in his mind suddenly became clear.

After reading it several times, he was even more breathtaking, no cliff can selflessly dedicate such profound insights to future generations, his greatness, let him be convinced, he knelt down deeply, sincerely performed nine kowtows, said: "Wu Yazi seniors, the younger generations inadvertently saw the masterpiece, shocked by the heavens, benefited a lot, I don't know how to repay." Please rest assured that the younger generations will definitely carry forward the "Secret of No Cliff" and refine more golden elixirs for the benefit of the world. ”

With that, he prostrated a few more times, and the stone walls around him collapsed, and just as he was secretly surprised, everything returned to calm. When the smoke and dust dissipate, but see that there is a cave behind the stone wall on the left, it is a space of a square circle, there is a stone platform on the inside of the space, and a wooden box and a small sword are placed at the upper end.

The small sword was about a finger long, a finger wide, and bronzed throughout, and I don't know what material it was made of, but when I saw it lying horizontally on top of the wooden box, it was like an upright soldier, dutifully guarding the box, which made him awe-inspired.

He walked over and reached out to pick up the sword, but he felt that the sword was very heavy, and the body of the sword was cold and sharp. He looked at it carefully for a moment and found that the sword body was as smooth as jade, and the tentacles were delicate and exquisite, and it was ingenious enough to capture the heavenly palace. At the end of the sword body, there are two small characters engraved like a ghostly axe, which is called 'Zhengang'.

Ling Xuan's heart was shocked, his hand was unstable, and he almost dropped this sword to the ground, he exclaimed in a low voice: "One of the nine great ancient swords, the true sword!"

He panicked, although the Nine Great Ancient Swords were not as good as the Ten Peerless Immortal Weapons, they were not within the reach of ordinary flying swords, wouldn't they be idle, why would they be here, so easily obtained by him?

He pondered it again and again, and finally carefully put the Zhengang sword back in its place, and said with sincere fear: "How can I be in Xia, it is the luck of three lives to see the "Secret of No Cliff", and I will never dare to use this sword again." ”

Such a powerful, famous and surnamed flying sword magic weapon, it is not a great honor can not be obtained, he has already obtained two innate spirit treasures, a superb immortal weapon, at this time, he never dares to hope for others.

After Jian Zhengang put the sword back in its place, when he raised his eyes, he found that there were also a few lines of small characters engraved on the stone wall behind the wooden box, and the full text was as follows:

Eight of the nine swords, the name is really strong, to cut the jade and cut the gold, such as cutting the earth, casting it with the gas of the eight directions, the power is superb, the non-god destruction is uncontrollable, the loss is very fortunate, there is no resentment, there is a fate, then it is fate.

It is very fortunate to have gained, and there is no resentment if it is lost.

A few short words, but a word to wake up the dreamer. There are more than 10,000 monks in the world, only he is fortunate enough to see the true sword, it is a great fate, how dare he violate the will of heaven and bear the true gang?

After figuring it out, he carefully picked up the Zhengang sword again, and couldn't put it down. However, Wuya's predecessor made it clear that this sword is not uncontrollable for the cultivation of the God Destroying Period, and now he only has the cultivation of the late stage of the out-of-body period, and there are still 108,000 miles of bumpy road to go from the God Destroying Period, although he has obtained the True Gang Sword, it is temporarily unusable.

He was sincerely afraid to drip blood to refine it, but when he saw a dark light flashing, the True Gang Sword turned into a streamer and submerged into his body, sleeping on his left chest like a dragon, firmly protecting his heart and veins, integrating with his blood and meridians, and he couldn't distinguish each other, but he clearly felt that it was in his body, and it was beating slightly with his heart.

Ling Xuan touched his chest, he wanted to touch the Zhengang Sword, but he inadvertently touched the wax torch that was placed intimately, he was slightly stunned, and immediately, thousands of melancholy arose, he sighed long, as if he didn't have the courage to take a look at the wax torch, and slowly retracted his hand, but he couldn't drive away the few reversed words that echoed in Wu Zi's mind no matter what: Bingyu, I love you......;

He sighed deeply again, shook his head and forcibly shook off the distractions in his mind, and moved his gaze to the wooden box.
