The library pavilion of Beili Palace is an ancient tower, standing in the middle of Longshou Peak and Taichu Peak, the tower body is black, there are nine floors, from a distance, this ancient tower seems to have experienced endless years. Chu Yifan flew out of the thick fog and landed on the stone platform outside the library pavilion, he raised his eyes to see, a burst of fragrance rushed to his face, took a deep breath and stepped forward.

The door of the library pavilion was open, Chu Yifan walked in with a step, and with a sweep of his eyes, he found that there were several figures on the first floor reading ancient books, most of these people were inner palace disciples who had just passed this trial, and they had the same purpose as Chu Yifan, they were all here to learn some techniques. The library was very quiet, no one spoke, the only thing that could be heard was the sound of flipping through ancient books, Chu Yifan walked lightly, came to a corner, he casually opened a yellowed ancient book, after a few glances, he found that this is a book that teaches people how to practice qi, and turned a few more pages, Chu Yifan put it back in its original place and continued to take the next one.

After about a stick of incense, Chu Yifan sighed lightly and said secretly: "Why are they all teaching people to practice qi, it's boring!" Chu Yifan was stunned for a while and then swept his eyes around, and finally landed in another place, and he walked lightly. After a few breaths, Chu Yifan came to the edge of a wooden staircase, and when he looked up, he found that there was a place on it that was not an ancient book, but a wooden tablet.

Chu Yifan walked up the stairs, his eyes showed a strange light, and he walked to the wooden board above the stairs, Chu Yifan reached out and took out a wooden tablet, opened it and looked at it carefully. What was recorded on this wooden tablet was not how to practice qi, nor was it a spell, but a Danshu that he had never heard of. From the wooden tablet, Chu Yifan learned that the Danshu originated from the Southern Regions Miaojiang, and its refining method was also ever-changing, with a wide variety, and the effect of a high-quality pill was unimaginable.

Chu Yifan's eyes were shining, thinking of the Dan Day of Beili Palace, and a smile appeared on the corner of his mouth, and then he secretly spoke: "If I learn this Dan technique, learn alchemy, and sell the refined pill at a high price, haha, wouldn't I be rich!"

On this day, Chu Yifan didn't go anywhere else, and devoted himself to studying the pill technique and how to refine the pill. It wasn't until the sunset hung obliquely and the evening bell rang that Chu Yifan left with some reluctance. After leaving, he did not immediately return to Taichu Peak, but went to the place where Elder Ouyang was, because Chu Yifan wanted to learn alchemy, and Elder Ouyang was the only one who could refine the pill in the entire Beili Palace.

Elder Ouyang's abode was not on the five peaks, but in a canyon, which was surrounded by high cliffs on both sides, and the top could not be seen at a glance. In the middle of the canyon is a huge flat land that extends deep into the canyon, and there is no end in sight. In the middle of the flat land there is a wooden house, this wooden house seems simple, but faintly reveals a sense of luxury, surrounded by several large trees. There was a yard in front of the hut, surrounded by a fence, and some flowers and plants were planted in the yard, and at this moment, a boy of about twelve or thirteen years old was weeding in the yard.

Chu Yifan walked over quickly, stood outside the fence, and said loudly to the young man: "Hey, I'm looking for Elder Ouyang, is he there?"

The young man glanced at Chu Yifan coldly, did not speak, and continued to weed. Chu Yifan's eyes flashed, and he continued to speak: "This little brother, I'm looking for Elder Ouyang, is he here?"

The young man put down the sickle in his hand, glanced at Chu Yifan again, and said in a cold voice: "I don't call him, I'm not your little brother, please call me Han Yam Boy!"

Seeing that the young man spoke, Chu Yifan cleared his throat and said with a smile: "Hanshan Yao Tong, I'm looking for Elder Ouyang, please report it!"

"What are you looking for my master? The cold mountain medicine boy was still indifferent, and turned around and walked towards the wooden house.

Seeing this, Chu Yifan immediately pushed open the low door on the side, walked in quickly, and came to the front of the cold mountain medicine boy. At this moment, I saw that a fire seemed to be burning in the eyes of the cold yam boy, staring at Chu Yifan deadly, and after screaming strangely, he said angrily: "Who let you in? Damn, you stepped on Master's favorite blue blood red, damn it, you get out of here! It's over, this time it's dead!"

Chu Yifan was stunned for a moment, and immediately took a few steps back, only to see that there was a leaf where he was just now, the red veins of the leaf spread, and the leaf was blue-green and glowing. Chu Yifan glanced at the leaf and hurriedly spoke: "I didn't mean it, I didn't mean it!"

The cold mountain medicine boy didn't bother with Chu Yifan again, and after tidying up the blue blood red, he walked towards the wooden house. Chu Yifan immediately followed behind, and continued to speak as if he was a little embarrassed: "It was indeed an accident just now, an accident, this... When will Elder Ouyang return?"

Hanshan Yaotong stopped, looked at Chu Yifan coldly when he turned around, pointed to the low door of the courtyard and said, "The door is there, get out!" After speaking, he walked into the wooden house, and slammed the door shut.

Chu Yifan sighed secretly and muttered softly: "Isn't it just a broken grass, as for that? Hmph, I can be self-taught without anyone to teach me!"

Leaving the canyon, Chu Yifan returned to Taichu Peak, and after a few thoughts, he found a broken furnace, the body of this furnace was full of dust, and it was full of spider silk, I don't know how many years it had not been used, and even more so, there was a small crack at the bottom of this furnace. After some cleaning, Chu Yifan looked at the gray stove in front of him with great satisfaction, and muttered softly: "It's done, I'm going to start alchemy!"

When he left the canyon before, Chu Yifan picked some herbs he knew, and at this moment he threw the herbs into the furnace, and according to the introduction of alchemy on the wooden tablets of the library pavilion, he began alchemy. The raging fire was burning, and the smell of medicine was in the nostrils, and after about a stick of incense, a roar sounded, echoing throughout the Beili Palace, and Chu Yifan flew out upside down and fell heavily to the ground. When he stood up, a puff of green smoke came out of his head, and his face seemed to be smeared with a layer of soot except for his teeth and eyes. He opened his mouth, exhaled a puff of white smoke, and squeezed out a few words: "Failed!"

Alchemy is not as simple as imagined, Chu Yifan did not give up after the first failure, he tried several times in a row in the next two days, and the result was still the same, ending in failure. Because the movement is too big, it has also attracted a lot of people's attention, but most of them are mocking and contemptuous. Until the failure on the third day, Chu Yifan did not try alchemy again, and even so, he did not give up. In the past few days, he has also been to the canyon to find Elder Ouyang, but every time he will eat closed-door soup. After thinking about it, Chu Yifan didn't go to Elder Ouyang again, because he knew that in a few days it would be the Five Peaks Heavenly Glory Meeting, and at that time, Elder Ouyang would definitely appear.

At noon on the fourth day, Chu Yifan came to the library again, this time he didn't look at the wooden tablets related to alchemy, but came directly to the second layer. The structure of the second layer is roughly the same as that of the first layer, Chu Yifan's eyes flashed during the steps, and he swept around, he found that the ancient books on the second floor were much less than those on the first floor, and what was even more strange was that in the middle of the second layer stood a wooden stick about a foot long, on top of the wooden stick was a round wooden board, on which sat an old woman with a rickety body and white hair, she closed her eyes, as if she was contemplating.

Chu Yifan glanced at the old woman a few times, and suddenly a chill arose in his heart, and he looked away, Chu Yifan found an ancient book and looked at it carefully, at this time, a vicissitudes of life voice suddenly sounded: "There is nothing you want here!" This voice can only be heard by Chu Yifan, because this voice was transmitted by the old woman sitting on the wooden board with her divine sense.

Chu Yifan was stunned for a moment, looked at the old woman, did not speak, and continued to read the ancient books after a breath, he didn't know that this sentence was said to himself. At this moment, the old woman's body suddenly flashed, disappeared in an instant, and was already in front of Chu Yifan when she appeared. Chu Yifan was so frightened that the ancient book in his hand fell to the ground, and after screaming strangely, he hurriedly retreated, and immediately spoke: "Are you a human or a ghost?"

The old woman smiled faintly, showed the few remaining teeth in her mouth, and said: "Where did the ghost come from in broad daylight, are the juniors so brave now? Little doll, don't be afraid, come here, come to me!"

Chu Yifan stepped back again, a strange light flashed in his eyes, looked at the old woman and asked, "Who are you?"

The old woman picked up the ancient books that Chu Yifan had dropped on the ground, put them in their original positions, and then spoke again: "I am the owner of this library pavilion, you come over and tell your mother-in-law what book you want to find." ”

Chu Yifan blinked, coughed dryly, and bowed after clasping his fists and spoke: "Senior Chu Yifan visited the landlord's mother-in-law, there was rudeness just now, and I hope that my mother-in-law will forgive me!"

The old woman took two steps forward with her hands behind her back and continued: "I know that your name is Chu Yifan, and you are a newly accepted apprentice of Taichu Zhenren, do you want to find some ancient books of magic? Come, follow me, there is nothing you are looking for here!"

Chu Yifan followed the old woman and walked slowly, and after a few breaths, they came to the third floor. The old woman stopped, pointed ahead, coughed a few times and said: "There are all lower multiplication techniques, with your current seventh-level qi cultivation practice, you can only practice lower multiplication techniques, go ahead, go and see if there are any magic powers you like!" After speaking, the old woman walked up the stairs to the fourth floor with her hands behind her back.

Chu Yifan hugged his fists and bowed, and said, "Thank you for the landlord's mother-in-law!"

"You don't have to thank the old woman, if you want to thank you, go and thank your master!" After speaking, the figure of the old woman had disappeared.

A ray of essence flashed in Chu Yifan's eyes, and he walked briskly towards the place pointed by the old woman. Compared to the first and second floors, there are fewer ancient books here, Chu Yifan flipped through it for a while, his eyes fell on a cyan ancient book, his eyes flashed, and he muttered softly: "Frozen Sword Formation, isn't this the technique practiced by Senior Sister Jiuge?"

Opening this cyan ancient book, Chu Yifan sighed lightly, because on the first page of this ancient book, it was explained that this technique was only suitable for women's cultivation. Chu Yifan smiled bitterly and put the cyan ancient book back in its place. After a few breaths, Chu Yifan's eyes looked at a yellowed ancient book again, and on the first page of this ancient book there were five black fonts - Tianyuan Qinglian Jue.
