Lu Xu only felt that the white light in front of him was blooming, and his body seemed to be weightless for a while, and he stumbled and fell to the ground.

"Hmm, your cultivation is so poor, how did you pass the assessment of the gravity array. Lu Xu heard a hint of surprise from the old man surnamed Zhou.

Lu Xu didn't dare to say anything, so he was busy and glanced around.

I saw that I was in the center of a wide hall, and the old man surnamed Zhou was standing not far from him.

The whole hall is the size of two or three basketball courts, and there are rows of bookshelves in the middle, and on each row of bookshelves, there are all kinds of books, or jade slips, and each bookshelf is covered by a translucent light curtain in front of it.

"The disciple's cultivation time is still short, so his cultivation is a little worse. After Lu Xu looked at it slightly, he bowed to the old man surnamed Zhou and replied.

"Oh, it seems that you are a tough person, otherwise you would never have been able to pass the gravity array. Okay, you come with me, all the basic exercises are here. The old man surnamed Zhou nodded, and led Lu Xu towards a row of bookshelves

"Tear and pull"!

After the old man surnamed Zhou used the token in his hand to swipe in front of the bookshelf, the light curtain in front of the bookshelf immediately disappeared into thin air.

The two of them approached directly.

After Lu Xu's eyes swept over the bookshelf, he couldn't help but show a hint of surprise on his face.

"These are the five elements basic exercises that you can learn for free at this stage, what, do you have anything you want to ask?" The old man surnamed Zhou asked with a smile after glancing at Lu Xu's reaction.

"Uncle Zhou, as far as the disciple knows, there should only be five basic exercises of the Five Elements, but it looks like it's much more than that. Lu Xu looked at the dozens of books in front of him, and said with a slight frown.

"Yes, there are naturally only five basic exercises of the five elements, but the establishment of this sect is also 20,000 years old, during which many predecessors of this sect have streamlined and evolved the basic exercises of the five elements, which has become these dozens of five elements basic exercises with various characteristics. The old man surnamed Zhou replied with a smile.

"I see, thank you Uncle for your advice, I don't know what kind of exercises Uncle thinks the disciple is suitable for cultivating?" After listening to this, Lu Xu understood the meaning of what Liu Feng and Huang Fei said just now, and asked the old man surnamed Zhou with a little hesitation.

"What is your spiritual root qualification, what kind of exercises did you learn before?" said the old man surnamed Zhou.

"I'm ashamed, the disciple is a five-spirit root qualification, and he used to learn the water attribute Bibo Gong!" Lu Xu replied respectfully.

"Oh?" the old man surnamed Zhou frowned slightly when he heard this.

"You are a disciple of Danyang Peak, you should learn the fire attribute and wood attribute exercises, which is conducive to alchemy. According to your qualifications, the old man recommends that you choose this pure yang gong. The old man surnamed Zhou took out a red book from the bookshelf and said to Lu Xu: "This book of pure yang gong, after the evolution of a sage of this sect, can speed up the cultivation speed to the greatest extent, after thirty or forty years, maybe you can have the opportunity to cultivate to the late stage of the qi refining period." ”

"Can you speed up your cultivation?" Lu Xu had a look of surprise on his face when he heard this, but then he couldn't help but change his face when he heard that it would take thirty or forty years to reach the late stage of the Qi Refining Period.

"Well, then you have to study hard to have a chance, your spiritual root is really poor, and you can only stay at the third or fourth layer of the Qi refining period for the rest of your life. The old man surnamed Zhou shook his head and said.

Lu Xu raised his hand and grabbed the red book in his hand, and at a glance saw the three big characters "Pure Yang Gong" written on the surface, and opened it and looked at it carefully.

Lu Xu took a cursory look at it, but found that although it was similar to the Bibo Gong in his mind, the cultivation method was extremely different.

To be honest, if this Pure Yang Gong could really speed up his cultivation, it was exactly what Lu Xu, who couldn't do with spiritual roots, needed. But when I thought that it would take thirty or forty years of cultivation to reach the late stage of Qi refining, I couldn't help but feel deflated.

In the final analysis, it is still a matter of spiritual root qualifications.

After Lu Xu flipped through the book and saw more than a dozen pages, he groaned for a while, and then said thoughtfully to the old man surnamed Zhou:

"Uncle Zhou, there must be gains in things in the world, since this pure yang gong has the advantage of fast cultivation speed, I don't know what flaws there are. ”

Hearing this, the old man surnamed Zhou glanced at Lu Xu in surprise, and when the disciple with a poor spiritual root heard the advantage of this pure yang gong cultivation speed, he couldn't wait to choose, but he didn't expect this young man to get carried away.

"Of course, there are defects, but they don't matter to your qualifications like the Five Spirit Roots. The old man surnamed Zhou said with a slight smile.

"Oh, I don't know what kind of defect it is, I hope Uncle Shi will tell me. Lu Xu asked slowly.

"The characteristic of this pure yang gong is that the overdraft potential accelerates the cultivation speed, and the defect is that the overdraft potential will lead to an unstable foundation, and those who have cultivated this pure yang gong will not be able to build a successful foundation for the rest of their lives. However, with your qualifications of the Five Spirit Roots, the chance of success in building the foundation is less than 1 in 10,000, so the old man said that it doesn't matter. When the old man surnamed Zhou heard this, he smiled slightly.

"Sure enough. The corners of Lu Xu's eyes twitched, and he smiled bitterly twice in his heart, and then fell into deep thought.

According to reason, with Lu Xu's Five Spirit Root qualifications, he should choose to cultivate this pure yang skill, but he has a great unwillingness in his heart. Once he cultivates, he can't build a foundation for the rest of his life, which is equivalent to ruining his path of cultivating immortals.

"Well, have you decided. The old man surnamed Zhou looked at Lu Xu, who was deep in thought, and said lightly.

Lu Xu fell into a dilemma in his heart, and after a while, he gritted his teeth and said, "Uncle Shi, the disciple has decided not to practice this pure yang gong." I don't know if Uncle Shi has any recommendations for exercises that can help build the foundation. ”

"Oh, I can't see that your heart is strong. ”

Hearing this, the old man surnamed Zhou glanced at Lu Xu playfully, then took out a green-skinned book from the bookshelf, handed it over, and said: "This one is the wood attribute Changchun Gong that has been perfected by the predecessors in the sect, the most important foundation, and it is also the most solid foundation among all the Five Elements Foundation Exercises. However, I would like to remind you that although this exercise focuses on the basics, it is the slowest cultivation speed. With your qualifications, I'm afraid that by the time Shouyuan is approaching, you will still only be able to cultivate to the third or fourth level. ”

Hearing this, Lu Xu took this Changchun Gong and looked through it carefully.

"You kid have to think clearly, don't be too ambitious and delay your cultivation. The old man surnamed Zhou stroked his beard and said.

"Uncle Shi, the disciple has thought clearly, so he chooses this Changchun Gong. Lu Xu closed the scroll in his hand and said firmly.

"Now there are fewer and fewer young people like you who are so determined in their hearts towards the Dao, after you go back, you must not first transform the water attribute mana of Bibo Gong in your body into the wood attribute of Changchun Gong, otherwise there will be a mana conflict and lead to madness. Seeing this, the old man surnamed Zhou reminded.
