In Yi Garden, in the Yang Courtyard, Ziyang Zhenren looked at Lu Yun and said with a smile: "Your achievements are beyond the imagination of the teacher, it is really amazing." For your progress in the past three months, the teacher didn't tell anyone, I want to surprise them at that time, let them know that our Yang Academy can also produce talents. Now that your sword technique has been completed, you just need to step up your cultivation technique. If you have any needs, you can tell the teacher, and what you can do will definitely satisfy your wishes. ”

Lu Yun looked at Ziyang Zhenren and said with a slight smile: "I remember that the last time I was in that Yin Soul Forest, Senior Uncle Xuanyin once performed the 'Yi Tianzhen Soul Technique', which was very magical. I don't know if the master knows the trick? The disciple is very curious about that, I once heard Senior Sister Ao Xue say that our Yi Yuan has four secret skills, I wonder if the master can tell the disciple something about this? ”

When Ziyang Zhenren heard this, his face suddenly became a little ugly, he looked up at the sky, and sighed: "Since you want to know, it doesn't hurt to tell you." In Yi Garden, there are indeed four secret techniques, and each courtyard has one secret technique. And Pian Pian is only the secret technique of our Yang Academy, and no one has ever successfully cultivated it for thousands of years. Therefore, among the four courtyards of Yi Yuan, it is not an exaggeration to say that our Yang Courtyard is the weakest courtyard. For a long time, Yangyuan has never produced outstanding talents, so Yangyuan has always been ranked last in Qiankun Yin and Yang. ”

Lu Yun asked with a surprised face, "I don't know why?" Could it be that the secret technique of our Yang Academy, the method is incomplete, or some other reason. Otherwise, why, no one has ever succeeded in cultivating? ”

Ziyang Zhenren sighed slightly: "After so many years, you are the only most outstanding person in our Yang Academy. Since you're interested, I'll let you see the trick. After speaking, he took Lu Yun into his room.

Ziyang Zhenren carefully took out a jade box from the inner room, opened it gently, and handed it to Lu Yun.

Taking the jade box, Lu Yun looked at the contents carefully, it turned out to be just a dark red silk, with countless patterns and words painted on it, but unfortunately it couldn't be seen.

"What is recorded above is the secret technique of this sect - the Five Thunder Zhengtian Technique! For a long time, except for the five words of the Five Thunder Zhengtian Recipe, the rest of the handwriting was blurred, so for thousands of years, no one had ever successfully cultivated. For so many years, no one has ever cracked the mystery hidden in this silk, and I hope you can gain something. Take it back and see it yourself, and remember to pay it back for me in three months. After speaking, Ziyang Zhenren handed the silk to Lu Yun.

Lu Yun looked at the magical silk that had been changing colors, and pondered slightly in his heart.

I remember that before coming here, the master once mentioned this "Five Thunder Zhengtian Formula", saying that this is the most masculine formula in the world, which can restrain all the yin and evil demons in the world, which is very magical.

Now it seems that there is indeed a hidden mystery, and not ordinary people can crack it.

"Thank you, master, the disciple will go back and have a look first, hoping to find a trace of clues and help the master solve this silk mystery."

Back in his room, Lu Yun closed the doors and windows, took out the piece of silk alone, and explored it carefully.

The silk is full of brilliance and flow, and a layer of mysterious aura faintly hides something, which makes people unreal.

Lu Yun gently held the silk and tried to input the true element of Yi Tian's magic recipe into it to see if there was any result.

With the input of Zhenyuan, I saw that the silk slowly emitted a dark blue light, but unfortunately the patterns and words on it were still not real.

Lu Yun took back the true yuan, and the silk returned to its original state, which was really weird.

After thinking for a while, this time, Lu Yun began to input the true yuan of the Taoist "Taixuan Split Heaven Dao", and carefully watched the changes in the silk.

It's a pity that the result is exactly the same, except for a slight difference in color, and nothing can be seen clearly.

Then, Lu Yun once again entered the true essence of the magic recipes of Buddhism, Confucianism, Demon Sect and Ghost Sect, but unfortunately it was still the same and there was no progress.

This made Lu Yun's heart startled, and the whole person fell into deep thought.

The quiet silk, Lu Yun's eyes suddenly shot out a cloud of colorful brilliance, at this moment, Lu Yun finally cast the ancestral "Heaven and Earth Wuji" technique, wanting to use the thought wave to detect the secret of this silk.

Lu Yun sent out seven thought waves, each with a different frequency, from the lowest of 240 times per instant, to the highest of 18,000 times per moment, divided into seven different sections, explored at different frequencies.

In just an instant, six of the seven thought waves emitted by Lu Yun were reflected.

Only the 18,000 thought waves that occur every moment are still spinning and exploring at high speed.

Lu Yun was overjoyed, knowing that this method was useful, but he had to increase the frequency of his thoughts.

After calming down, Lu Yun Wuyue sat facing the sky, and at the same time raised the frequency to 24,000 times per instant, thinking that this time the news should be detected.

To his surprise, although there was a little progress this time, he still couldn't break through the defenses of the thought wave.

Lu Yun's face changed slightly, and his unconvinced psychology made him once again increase the frequency to 36,000 times per instant, but the result was still the same.

In the end, Lu Yun kept raising the frequency of the thought wave to 108,000 times per instant, and only then did he barely enter the inside of that layer of thought wave and saw some patterns and words.

It's a pity that Lu Yun only supported it for a while, but he couldn't support it and had to give up.

Seeing that he was covered in sweat and soaked through his clothes, Lu Yun was so tired that he didn't want to move.

He never thought that there was such a layer of incredibly high frequency of thought waves on this silk, which made him try his best, and he couldn't support it after just entering it.

At this time, Lu Yun had already entered the ninth realm of the Ten Realms of Cultivation, the primary stage of immortality.

To talk about cultivation, it is already extremely amazing, but this attempt made him realize that his cultivation is still far behind, and he needs to work hard.

Jing Jing Ji Gong recovered the consumed true yuan, and saw that around Lu Yun's body, countless aura of various colors formed a colorful light mask outside his body, which was very beautiful.

At this moment, in order to recover the consumed true yuan as soon as possible, Lu Yun displayed his family's peerless learning, Heaven and Earth Wuji.

Heaven and earth are divided into nine layers, and the fifth layer is the realm of "10,000 yuan to one".

The biggest feature of this realm is that when recovering the true element, it can directly absorb the hidden heaven and earth aura in the air and quickly restore the lost true element.

At this time, Lu Yun had already begun to enter the seventh layer realm of "Heaven and Earth Boundless", "Heaven and Earth Tongchun", and his cultivation was extremely profound.

After only a while, he saw the brilliance around him flickering, and the aura around him was instantly inhaled into his body.

Waking up, Lu Yun once again looked at the magical silk in his hand and pondered.
