Sandalwood mixed with the scent of logs permeated the entire nine-story library, and the natural aroma gave people a sense of calming and condensing. Ye Yu only went in for a few minutes, and the whole person felt an unprecedented calm.

"I observe that your mental power has reached the stellar level, but the level of physical skills seems to be very low." Aix asked Ye Yu as he walked towards the depths of the attic.

Ye Yu heard Aix's words, his heart moved, such a high-level physical arts master is here, why don't he tell the truth about himself, maybe he has some way to help him. And his own combat experience, as long as someone who cares about it investigates a little, you can know.

"Professor, I was once seriously injured by a master of physical arts, and although I was lucky enough to save my life, all the energy I gained from practicing physical arts before was dissipated!" Ye Yu immediately explained his situation concisely, and then looked at Ax with a blank look.

"Serious injuries shouldn't be like this, right, what level is the other party? Could it be the people of the Empire? Ax glanced back at Ye Yu in some surprise, and asked with a slight frown. Although he didn't know the specific situation of this student, it was not possible for anyone to seriously injure a person whose telekinesis level had reached the stellar level.

"It should not be lower than the eighth order, he is a killer!" Ye Yu did not hesitate and continued to answer.

"A killer whose combat power level is not lower than the eighth order, why did he kill you?"

Ye Yu saw Aix suddenly look back at him, and his heart was numb, but as long as his true identity was not discovered, he was not afraid. Immediately, he adjusted his mood and replied, "The kid was serving in the Silver Dragon Guard at the time, and this killer he met after destroying a pirate organization. ”

"It turned out to be you, so it seems that I still underestimated you before. The academy has already obtained the video of your battle, I am really curious how you did it......" Aix heard Ye Yu's answer, his eyes lit up, he was also a soldier at the beginning, so he was naturally interested in this battle. He really couldn't imagine how Ye Yu defeated the other party with such a weak defense force at the beginning, and even captured a mothership.

"At that time, it was not only me, but also a master to help, plus some other factors, I was also lucky." Ye Yu knew that he couldn't expose the existence of Jinshan, so he immediately imagined the existence of a master.

Aix smiled, he was dozens of years older than Ye Yu, so he naturally knew that the other party didn't want to talk about this issue. Then he changed the subject and said, "I'll take a look at your problem, don't move yet." ”

At the same time, Ye Yu suddenly felt two fingers against the center of his eyebrows. Then, a warm energy slowly swam along the center of his eyebrows towards his limbs and internal organs.

After more than ten minutes passed, Aix looked at Ye Yu with a pale face and said, "Your question is a little strange, it seems that energy can't be saved, and it feels like your entire body is like a huge loophole, constantly dissipating new energy in your body." ”

Ye Yu nodded, did not speak, he had no way to solve it himself, he could only pin his hopes on Aix.

"This kind of injury is very strange, according to the reason, with the blow of an eighth-order master, you definitely have no chance of survival. But you survived, but your original physical skills were completely unwieldy, and your energy couldn't be regathered. Aix kept pressing his temples, as if thinking about something.

"Are you still practicing your previous physical arts?" Ax asked again, although all kinds of physical techniques can be practiced at the same time, there are also some special physical techniques that will conflict with other physical techniques.

"I've tried a few times, but I'm still failing." Ye Yu couldn't help but feel a little regretful when he thought of the set of physical techniques that had been passed down from his family, and that set of physical techniques was to some extent his concern for his parents.

As the two men were talking, they had come to the east of a bookshelf, and Professor Aix thought for a moment and pulled out a book that seemed to be written on silk. The book was yellow, without any cover, except for three words written near the right that he couldn't read.

"This is a book I got from an imperial family back then, called 'Mountains and Rivers'. I looked at the contents, and it was more obscure. According to my later multi-faceted verification, this should be a high-level cultivation method for the royal family. Professor Aix turned around and handed the book to Ye Yu, with a hint of remembrance in his expression.

Ye Yu took the book handed over by Professor Aix, and his tentacles were cold and silky. At this moment, Ye Yu found that he seemed to have a familiar feeling with this book.

"This is a fragment, according to the introduction at the beginning of it, there are a total of twelve stages in this book, but this book only records the sixth stage, that is, the sixth stage of physical arts." Ax looked at Ye Yu's expression and continued: "However, the requirements of this magic book are relatively high, and there are too few people in the federal territory who are suitable for practicing this magic technique. ”

"What are the requirements?" Ye Yu didn't worry, he knew that since the other party took out the book, then he should meet the conditions.

"First, until this technique has been cultivated to the sixth stage, it is not possible to practice other body techniques. Of course, this type of mental power does not count.

Second, only people who do not have the energy brought by other physical arts in their body can practice it, otherwise forced practice will inevitably explode the energy and die.

Thirdly, the practitioner must have a strong mental power! ”

After Ax finished speaking, he patted Ye Yu on the shoulder and said, "That is to say, those who have now practiced physical arts, unless they abolish the hard-earned energy, must have strong enough telekinesis!" Moreover, when practicing this method, you have to endure the temptation of other body magic techniques in the early stage#......"

Ye Yu listened to Professor Aix's words quietly, and he understood that there was no effective way to solve his problem now. And in the future, he will definitely go to the front-line combat mission, and it is definitely not so safe to have only mental power.

“…… Of course, the most important point is that this mantra is said to increase the external energy of the body in the process of practice, and this mantra seems to improve the body's internal defects. I think since you don't have a better way, maybe practicing this method is a chance for you......" Ax said this, his expression was a little hesitant, but finally he sighed and said: "There is no absolutely perfect method in the world, and this method has a flaw, although it has no effect in most cases, it is an unstable existence after all. ”

"Professor, I understand this truth, and I also know that only high-level cultivation methods can go further and become stronger. In most of the low-level methods, the practitioner is only at the level of a mid-level master throughout his life. "What Ye Yu knew, the cultivation method left by his parents was much more powerful than the ordinary physical art cultivation method, and most of the practitioners had the ability to challenge beyond the level.

"Good! Be bold as a soldier! Aix nodded heavily and continued, "This book is just an added bonus, and I can be your direct mentor if you want!" ”

"Students willing!"

Ye Yu knew that on the way to cultivating physical arts, if there was a high-level cultivator who was willing to take it, it would definitely be a thing that could be encountered but not sought. However, most advanced practitioners want to go to higher levels, and naturally they don't want to waste time with students. Since Professor Aix took the initiative to propose it, then Ye Yu naturally had no reason to refuse.

"Okay, here's a translation of "Mountains and Rivers Jue" that has been translated to the third stage, you can understand it first. However, in the future, you still have to strengthen your learning of the language of the country, after all, this book is from the Empire, and the person who wrote this book is also from the Empire. You can understand their words, and you can improve the speed and accuracy of your practice! ”

Aix took out a booklet from the place where the "Mountains and Rivers Jue" had just been placed, handed it to Ye Yu, and then turned to leave.

Ye Yu didn't dare to be the slightest slack, and immediately found a seat, and sat up with five hearts. At the same time, the translation opened the first page automatically.

"In the twenty-seventh year of the empire, I remembered that the empire had thousands of physical skills, but most of them were rude, and I could not practice the essence. So, why don't I make a new one...... I have spent a long time searching for the masters of physical arts in the empire and learning the essence of their physical skills.

Twenty-three years later, I am already dying, and I cannot get the essence. My heart is unwilling, or climb the mountain and exhale, or think near the river, and finally understand the mystery of physical arts, is to write this recipe...... This is my view of the mountains and rivers and the feeling of creation, Gu called its name "Mountains and Rivers" ......"
