At the end of a competition, the two were finally separated.

It is not difficult to see that Ao Jue has recently become a little stronger and has more combat experience, which is undoubtedly related to the recent fight with fierce beasts in the forest.

Ao Jue is a material that can be made, and Ao Zhan is even considering teaching him some of the essence of blood alchemy for reference and verification, so that he can embark on his own cultivation path in the future.

"Without the right exercises, not only will the realm improve slowly, but even the combat effectiveness will be greatly reduced, and in the long run, I'm afraid the cultivation will stop. Ao Zhan looked around at a few people, "In the future, I will definitely find a suitable exercise for you." ”

"Thank you, master!" several people replied happily.

Then Ao Zhan returned to his courtyard and opened the Thunder Emperor's Thunder Ring. But it's a pity that there is no collection of exercises at all except for the Thunder Emperor's own core inheritance, Ao Zhan couldn't help but smile after thinking about it, and secretly sighed that this Thunder Emperor is a high-minded and arrogant master, and he completely disdains other people's methods.

Helpless, Ao Zhan went to the Treasure Pavilion.

Showing the token of worship given by the pavilion master, he found Jing'er under the leadership of a maidservant, and then Jing'er led him to the library on the top floor, according to Jing'er, there are 1,864 yellow-level exercises, 360 Xuan-level exercises, and only 12 earth-level exercises are not authorized to view.

The huge Zhumen is old, and the door nails are delicate and round, revealing the vicissitudes of life, Ao Zhan can't help but sigh in his heart, this huge library building has gone through many generations of efforts to have today's scale.

"Hey, I don't know if there is a Heavenly Rank Exercise in this library?" Ao Zhan asked with a smile.

Jing'er's face changed, and she lowered her voice and said mysteriously, "There used to be a heaven-level exercise in the library building, but something happened later, which caused this exercise to be lost, and then the library was banned for many years......

"It's a shame. Ao Zhan was stunned for a moment and sighed secretly. If he hadn't lost it, he would have borrowed everything.

Jing'er buckled the door, and with a 'click', a pair of strange beast door locks were revealed, and she slowly opened her eyes, and she made a mechanical sound, "Is there a key?"

"Yes!" Jing'er nodded hurriedly, handed over a pair of beautifully painted gold keys, and then inserted them into the eyebrows of the pair of strange beasts at the same time.

With a 'crunch', the vermilion lacquer door slowly opened, and what was surprising was that behind the door was a slowly rotating black hole, pitch black and bottomless, like a huge mouth about to swallow the whole world.

"What's going on?" Ao Zhan frowned, really taken aback.

Jing'er bowed slightly and said, "Since that incident, this library has been changed into a small world by the seniors in the pavilion, and when you enter the door, you must not only let the ghosts and charms feel the token of worship or elders, but also have the door key in my hand." The most important thing is that if you want to come out of this small world, you must pass on the Gong Elders. ”

Ao Zhan was stunned for a moment, frowned and asked, "Who is Elder Chuangong, is he inside, and how can I get out through him?"

Jing'er pursed her lips and smiled, "Everything will be clear when you go in." ”

At this point, Ao Zhan didn't bother to talk nonsense, and jumped into the black hole. Suddenly, the sky swirled, as if even the soul had temporarily stagnated, and a sea of stars suddenly appeared in front of me, pure and gorgeous.

This feeling was similar to when he entered the Heavenly Machine Realm, and Ao Zhan couldn't help but wonder if the two were related.

"Huh?" with a soft sigh, Ao Zhan quickly came to his senses.

There are no rows of bookshelves in the place where you stood, only a bottle of stone sculptures of different shapes, either human or beast, and the stone carvings hold a scroll in different postures.

"Yellow Order Exercises, "Over the Mountain and Seal Decision". Ao Zhan casually took a roll and spread it out. His gaze swept over, and what was recorded in it was a kind of palm method secret book that used spiritual power to mobilize the essence and energy of the whole body, and it was equipped with a method of cultivation.

"Qi Shi three befriending, shun the qi house, through the two veins, will correct the acupoints, give it the nine lives of yin and yang, and send it by the Lao Gong ......" silently recited the mantra, Ao Zhan did it, and suddenly felt that the dantian was hot, and a faint air flow began to move according to the meridians on the cheats, and finally slowly converged on the Lao Gong acupoints in both palms.

"The essence of the mountain seal is to use the qi to adjust the spirit, so that the original weak spiritual power can exert an indescribable power with the magic of the acupuncture points, but the founder of this exercise obviously does not know the acupoints of the human body, so the power exerted is not smooth enough. If it can be improved, this technique will not be ranked in the Yellow Rank!" Ao Zhan shook his head and sighed.

"Okay, well said!" A voice sounded suddenly, startling Ao Zhan.

Looking at it, an old man was already standing three meters behind him at some point, Ao Zhan's heart was shocked, he could make him who cultivated blood alchemy unaware, and his cultivation would inevitably be transcendent.

"Who are you?" asked Ao Zhan vigilantly.

"You might as well take a guess. The old man stroked his snow-white beard and asked indifferently.

Ao Zhan took a deep breath, forcibly calmed himself down, rolled his eyes and said, "Could it be that you are the Elder of the Gong?"

"You're very smart, no wonder you just tried it and saw the shortcomings of the mountain seal. Yes, I am the Elder of the Library Building. The old man showed a hint of a smile and continued, "For thousands of years, there have been geniuses who can see the shortcomings of this exercise, such as carp crossing the river, but there are very few who may have recreated it. How about young man, are you okay?"

"I don't have that much time to spare!" Ao Zhan replied angrily.

"The young man is noisy, why don't you take a look at this "Pure Heart Secret Collection", and see what clues you can see?" said the old man, throwing a bamboo book to Ao Zhan.

Ao Zhan raised his hand to take it, and when he spread it out, he found that this bamboo scroll was exactly the same as the bamboo scroll that had been printed over the mountain before.

"The exercises here should all be manuscripts. Ao Zhan suddenly understood.

"Yes, this is only a branch of my Treasure Pavilion, so naturally it is impossible to store authentic works. The old man stroked his beard and said leisurely.

Ao Zhan nodded, and began to look at the secret of the clear heart, "The heart, the initiator of all thoughts, one good, one evil, one clear and one turbid, choose it to be clear and turn into two qi, and use two qi to educate the mind, and regard it as quiet!"

After trying it according to the script, I suddenly felt relieved in my heart, as if the fatigue of my body was relieved, and the Lingtai was inexplicably ethereal, and I thought more rationally.

After pondering repeatedly, Ao Zhan finally felt a little touched, raised his head and said, "The founder of the pure heart and secret is very right, the heart, the beginning of all thoughts, divides good and evil thoughts into turbidity, he only takes its 'clear', with it to turn the movement and static two qi, and uses the 'movement' to refer to the confirmation, only to keep its quiet qi, and to nourish the mind and strengthen the original spirit, which is also ingenious!"

The old man glanced at Ao Zhan in surprise and praised, "You are really a talent, and you can understand the charm of the pure heart and secret at this moment." ”

Ao Zhan had no sorrow or joy, and continued, "In fact, how can the human heart be simply good and evil? Joy, anger, sorrow, thought, sorrow, fear, shock, life, death, eyes, ears, nose, mouth, and other seven emotions and six desires are not the human heart. Different people have different hearts, and not everyone is suitable for this book of pure hearts, just take its essence. ”

"Yes, other people's is someone else's after all, you can understand this, the understanding is really good!" the old man smiled slightly, his eyes were full of appreciation, "The 'Qing' pursued by the pure heart and secret seems to be a clever way, but in fact, the pure person is ever-changing, if you can understand it according to yourself, you can also transcend the Yellow Order." In the past, the pavilion master picked up the "Pure Heart Secret Collection", guided by his own body understanding, which lasted for a season, ingeniously blended the pure air with the sound of the guzheng, and created a self-created song of the unpredictable "Autumn Water", which is really amazing!"

Ao Zhan couldn't help but be stunned, he listened to "Autumn Water" twice, but where did he think of this, it was all a chic tune.

"The sound of the guzheng and the 'quiet' qi seem to have the same end, but if you want to blend them into one, I am afraid that it will be difficult, and that woman is really powerful!" Ao Zhan sighed.

"Young man, you're not bad either. Come on, take a look at this volume of "Purple Mansion Divine Pill" again!" As he spoke, the old man threw out another volume of exercises.

Ao Zhan became more and more interested, and he immersed himself without saying a word, and realized it alone.

The Purple Mansion Divine Pill is a secret art of cultivating the inner Dan, paying attention to the outside to the inside and from the inside out, it is a rather mysterious method of breathing, once the purple qi is bred in the dantian, it can carry the power of heaven and earth.

"It is obtained from the sky, contained in the dantian, and condensed to mobilize the power of heaven and earth......" Ao Zhan said to himself, exuding a faint purple aura around his body.
