On that day, on the second floor of the library, it was close to noon.

Sitting cross-legged on the ground, his closed eyes trembled slightly, Li Yun suddenly exhaled a breath of turbid air and opened his eyes.

"How? But getting started?"

On the side, Principal Cao's words of concern came.

Li Yun looked away from the morning light and said with a light smile: "Thank you, principal, I am fortunate not to be dishonored." ”

"It's good to get it. ”

Principal Cao also breathed a sigh of relief, and said disdainfully, "I don't know how you comprehended the true meaning of the boxing technique, judging from the progress of your practice of the Fetal Yuan Gong, your comprehension is just in the middle and bottom, could it be that your qualifications are reflected in the fighting-related?"

"Maybe it has something to do with the fact that I like fighting, isn't it true that interest is the best teacher? ”

Li Yun explained with a smile and stood up.

"Where did you hear that?"

Principal Cao muttered, and did not delve into it, but reminded, "Since you have already understood the mysteries of the Fetal Yuan Gong, then cultivate it to the fullest extent as soon as possible, there is not much time left for you, after all, this is a yellow-level martial art, which is only practiced by martial artists in the body refining period, and once you enter a higher education college in the future, you must prepare for breaking through the condensation period." ”

"Yes, I know. ”

Li Yun nodded, stepped over the Chiyan vicious dog lying in the middle, and came to the counter.

"But don't be obsessed with it, which will lead to a blind eye and miss the practice!"

Principal Cao looked solemn again and warned.

"With the qualifications you are showing now, even if you don't practice this kung fu, you will definitely be able to reach the ninth level of body refining, "Fetal Yuan Gong" is just the icing on the cake for you, and your time is running out, you must grasp the degree of it!"

"Hmph, I advised you when you asked me this before...... That's it, I hope you can really restrain yourself, there are only more than two months left before you are promoted to the higher academy, and even with your qualifications, at most two layers of afterbirth clothes will be shed at this time, but I hope you will only shed one layer-"

"Wait!"

Li Yun suddenly interrupted him, "What is a two-layer afterbirth? Isn't it just one layer?"

Isn't the rebirth of the fetal yuan gong a one-off?

"Ugh. ”

Principal Cao was stunned for a moment when he saw Li Yun's reaction, and then remorse flashed on his face, and he said angrily, "It turns out that you didn't even inquire about the efficacy of the Fetal Yuan Gong, so you came to me to guide your cultivation?"

"It's not too late to know now. ”

Li Yun immediately gave up his hand and said with a serious smile, "Please also ask the principal to inform me." ”

Principal Cao paused, and sighed: "That's it, sooner or later, you will know about this matter, the Fetal Yuan Gong is a rebirth, comparable to the miracle method of changing the heavens and the earth, there is no realm level, but as a martial arts method, you can naturally continue to refine and deepen——"

"Boy, I told you before, once you get started, as long as you follow the steps and cultivate the twelve movement and static diagrams on it one by one, it will be considered a thorough practice, right?"

"Yes. ”

Li Yun nodded, revealing a look of attentive listening.

"But that's just the first step!"

Principal Cao said in a heavy voice, "If you want to have a better fetal element and get a higher qualification, you must keep practicing those twelve diagrams in a loop! Every time you cycle, your own fetal element will be upgraded by one level! The root bone qualification can naturally go up to a higher level!"

"That's—"

Li Yun suddenly moved.

"I know what you're thinking, but don't be greedy!"

Principal Cao interrupted in a cold voice, "The cultivation of the Fetal Yuan Gong, every time you cultivate the twelve diagrams, the difficulty will be ten times that of the last time! Even if you have good qualifications, if you want to complete the practice, it will take at least a week to half a month, and when you wait for the second time, it will be more than two months or even five months! The third time is two to four years! How many times do you think you can cultivate now?"

Li Yun pursed his lips when he heard this, but when Principal Cao thought he had given up, he didn't want to-

"Then does the principal know how many times the Fetal Yuan Gong can be cultivated in a cycle, and what is the difference between the superposition of the number of times?"

Li Yun suddenly opened his mouth and asked with a curious look.

"Do you know what these things do?"

Principal Cao immediately said vigilantly, "Isn't it because you still don't give up?"

"You're too careful. ”

Li Yun smiled bitterly, "If the practice of this skill is really as you said, then what can I do even if I don't give up?

"Then why do you ask?"

Principal Cao was not easily fooled, he just shook his head and said, "The old man can be regarded as having a good understanding of your temperament, thinking about excellence and pursuing perfection all day long, in order to make up for the foundation, even the junior martial arts want to bother to retrain, what else can't be done?!"

"I have to say, your ideas or wishes are good, but I don't know that no one is perfect, even if it is a celestial man, you need to know that people's energy is limited, as a qualified martial artist, you should use your strengths and avoid weaknesses, instead of learning from each other's strengths, blindly pursuing perfection, this is an obsession with the demons!"

"The headmaster is taught. ”

Li Yun quietly listened to Principal Cao's words and said with a light smile, "But I'm really just curious this time, and I want to know the limit of this magic skill." ”

"You-"

Principal Cao looked at him speechlessly, and finally sighed helplessly, "If I don't say it, are you going to inquire outside again?"

Li Yun smiled silently.

"Hmph. ”

Principal Cao's face turned pale, and he finally spoke, "Kindness is treated as a donkey's liver and lungs, it doesn't hurt if I tell you, whether you can keep your heart demon or not, anyway, when you graduate, it will have nothing to do with the old man!"

"The Mercenary Guild has been sitting on the "Fetal Yuan Gong" for hundreds of years, and according to the feedback of countless martial artists who practice this skill, they have long summarized the classification of a set of fetal clothes, from bottom to top, they are pure blood birthclothes, Jingyuan birthclothes, pure Qi birthclothes and Shenyu birthclothes"

"Among them, the blood-purifying afterbirth garment only needs to be obtained by practicing the fetal yuan gong once, and once it is cultivated, even if the previous qualification is poor, it can also become an upper-middle posture, that is, the level that can successfully graduate from middle school. ”

"If you practice for the second time, it will be the Jingyuan birthworth, once you cultivate, your qualifications can be doubled, if you want to describe it, it is almost the level of the top thirty students in the grade, and you should be able to have the cultivation of the seventh layer of refining when you graduate. ”

"And the third pure Qi birthplace is the limit of most people who practice this martial arts, after all, the hundredfold increase in difficulty takes time that ordinary people can hardly bear, and once they cultivate the pure Qi birthplace - or take ordinary people as an example, their qualifications should be able to reach the level of the head of the ordinary grade, if they are a little more diligent, they should have the cultivation of the eighth layer of refining when they graduate. ”

"The last fourth time is the Divine Jade Birthworth, this realm in the entire history of the Mercenary Guild, only one person has ever reached it, hum, it's really the world's bigness, I haven't broken through for more than 40 years, just to practice this broken thing......"

Speaking of this, Principal Cao's face was full of confusion and disdain.

"And then?"

Li Yun saw him stop and immediately asked.

"What, then?"

Principal Cao looked at him strangely.

"You didn't mean the Divine Jade Fetal Coat. ”

Li Yun reminded, "What is the miraculous effect of this birthworthy, what about the martial artist who cultivated the birthworth, and what amazing achievements can he have in the future?"

"Bullshit achievement!"

Principal Cao suddenly spewed out swear words, looking at him with an idiotic look, "Do you think that a martial artist in the body refining stage who is in his fifties and nearly sixty years old has decayed qi and blood and lacks energy, is it possible to break through the qi condensation stage?"

“......”

Li Yun was speechless.

"As for the Divine Jade Fetal Coat—"

Principal Cao snorted, "For ordinary people, at most, they will raise their qualifications to a genius level like yours, and they may not be as good as you, this kind of qualification-when you graduate, you should be able to have a ninth-level cultivation of the refining body, but the time spent during this period, heh." ”

After sneering, Principal Cao looked at Li Yun with a solemn expression.

"This is clear, right? So, you are a genius, your qualifications are no less than the Divine Jade Fetal Clothes, and compared with those mercenaries, it is completely different from heaven and earth, this "Fetal Yuan Gong" for you, you only need to practice once, with the blessing of a layer of pure blood birthplacen, I estimate that it is enough to support you to the peak of the ninth layer of body refining, and then if you continue to practice, it will be completely useless!"

Li Yun nodded thoughtfully and muttered, "In other words, even if it is the Mercenary Guild, it is not sure if the Divine Jade Fetal Clothing is the limit of the Fetal Yuan Gong?"

"How can you be sure?"

Principal Cao said with a smile, "If you find a martial artist in the refining stage who can live for four hundred years, you can use it to verify one or two." ”

"Huh. ”

Li Yun also smiled, and after revealing this topic, he asked instead: "Principal, I don't know if you can let the cafeteria deliver a few more meals a day in the remaining days?"

"Can you still eat?"

Principal Cao's eyes widened, he looked at him in surprise, and then waved his fan, "Forget it, you can tell Wang Hong directly about this matter, don't bother me, the old man just begs you to work hard in the past few days, so that you can improve your cultivation to the eighth layer of body refining, seeing that graduation is imminent, but you are always dangling on the seventh layer, which really makes people panic!"

"There is no urgency. ”

Li Yun said confidently, "I am now deliberately controlling the growth of cultivation so as to consolidate the foundation, you can rest assured, as long as the principal helps me hide it during the graduation exam, then I guarantee that I can break through the ninth layer of refining body during the vacation!"

"Hmph, I don't need you to remind you, the kid who talks a lot!"

Principal Cao squinted at him, "Although I don't know what you are hiding and not telling the truth, what kind of wonderful martial arts you are cultivating behind my back, but the old man still said that, grasp that degree by yourself, don't lose a big one because of a small one!"

Well?!

Li Yun raised his eyebrows slightly when he heard this, and said quietly: "Principal, what do you mean by this?"

"I'm really old and confused, I don't know your little tricks?"

Principal Cao snorted coldly, "Your recent changes are all under the nose of the old man! Hmph, what a miracle skill, you can actually change the external expedition of the Brute Dragon Fierce Battle Body that is about to be completed!"

"Moreover, I see that your skin is like condensed fat recently, your face is like warm jade, and your breath is even softer and longer, if there is nothing, obviously this skill also has the power of detoxification and shaping, and the ability to nourish the heart, and go further, I am afraid that it is the threshold of the unity of heaven and man!"

"Especially today, when you came over in the morning, I found that not only was your mouth fragrant, but also the body was full of dragons and tigers, yin and yang blended, and the body surface faintly exuded a trace of the mellow fragrance of Yuan Yang, which looked like a pure yang and innocent body, and it was a bit plausible, but it can be concluded that you must be invincible to all poisons now, and you can almost catch up with half of the superb martial arts!"

"Boy—"

Principal Cao looked at him with ill intentions, and said quietly: "Don't tell the old man, you don't know these changes yourself?"

The whole body is fragrant, pure yang and unsullied body, and all poisons are not invaded?

Li Yun looked stunned, and really lowered his head and sniffed under his armpit, but he didn't smell anything, "Principal, where did you get any mellow fragrance? Why can't I smell it?"

He was also relieved in his heart, if he really had a body fragrance in the future, it would really be ......

Syllable.

Principal Cao's forehead was bruised, and the bamboo fan slapped on the counter, "It's not smelling! It's looking, it's the old man who perceives it with cultivation!"

"Ordinary condensation period martial artists, once you reach the eighth layer of condensation, the true qi begins to return from the acquired to the innate nature, and even in the eyes of the martial artists of the Guiyuan period, you are simply a big fat boy who stands out from the crowd, washed white and clean, and has a fragrant whole body!"

"And even if you are not a master, with your peculiar physique now, once an ordinary woman approaches, I am afraid that she will immediately be unable to help it, her face is red and her body is crisp, her eyes are rippling, and she is leaning against you!
