After Zhang Yuan returned to his practice room, he took out the "Wunian Medical Codex" in the ring and beat it vigorously: "Master, Master, come out quickly, Zhang Yuan has something to ask you!!"

"Hehe, what's wrong, what's going on again?" said an old man with gray hair as he floated out of the medical dictionary and smiled.

"Master, look at my current situation, can I break through the middle stage of the Jindan Realm?" Zhang Yuan asked the white-robed old man with apprehension in his heart.

The white-robed old man carefully felt Zhang Yuan's physical condition, and his face was happy: "You guy, what kind of pill have you taken, how can you make progress so quickly, this physical condition can break through, and there will be no sequelae." ”

Zhang Yuan was overjoyed when he heard this, and hurriedly replied: "No, I fought hard in Monk City, and in the end, we both lost, he ran away, and I didn't chase him." ”

"At that time, I was very seriously injured, there was no good place on my body, the meridians were blocked, the internal organs were broken, and even some displacement, but after a few days of recuperation, I felt that I was stronger. Zhang Yuan added.

"Sure enough, a life-and-death battle can stimulate people's cultivation speed faster Ah, okay, you can break through at this time!!" the white-robed old man said with a smile.

"Wait, Master," Zhang Yuan still had a question, and took out the "Unintentional Medical Codex" from the precept, "How should I treat this medical codex, should I cultivate it?"

The white-robed old man took the medical codex, opened it page by page, and read it carefully, with a serious expression.

"How is it, Master, this medical codex?" Zhang Yuan asked cautiously.

"Stinky boy, you have really picked up a treasure, this medical canon can be said to be the most advanced medical canon I have ever seen, and the exercises recorded in it are really a wonderful word!!" The white-robed old man was amazed, and his fingers stretched out, "Come on, stick your head over, and I will pass on the contents of this book and my understanding to you." ”

"Okay!!" Zhang Yuan put his forehead close to the fingers of the white-robed old man, waiting with anticrative antiquation for this "Unintentional Medical Codex" that the white-robed old man was full of.

The white-robed old man's cold fingers pointed at Zhang Yuan's forehead, and at the same time as he felt a burst of coolness on his forehead, a tidal wave of information suddenly poured into Zhang Yuan's mind, which contained the Zhoutian running route, moves and the understanding of the white-robed old man planned in the "Unintentional Medical Codex".

"This, this is ......" Zhang Yuan felt the tidal wave of information in his mind, and felt incredible, "This way of running every day, this, this is much more clever than the "Wu Nian Medical Classic", this kind of efficiency, this way of bursting true qi, even the power when casting martial arts is different." ”

"There is another thing you haven't seen, the true qi cultivated through the Zhou Tian operation method of the "Unintentional Medical Codex" is much higher than that of the "Wunian Medical Codex", and when the time comes, you will have no trouble dealing with enemies of the same level, plus the two moves of Xingyi Fist and Xingyi Ascending Dragon Slash recorded in it, which are enough for you to run rampant at the same level. The white-robed old man said with a smile.

"That's really amazing, Master, can I cultivate it right away, transform my Zhou Tian and True Qi?" Zhang Yuan couldn't wait to cultivate this medical canon.

"Of course you can, I suggest that you better transform your Zhou Tian and True Qi, and then break through, so that the probability of breakthrough and safety can be guaranteed," the white-robed old man changed his words, "However, I advise you, it is best to hide the taste of the Unintentional Medical Code when you fight in the future, and don't use those two martial arts arrogantly!!"

"Why?" Zhang Yuan looked at the white-robed old man in confusion.

"It's time to tell you some things, lest you really suffer by then. The white-robed old man sighed.

"Boy, although in our world, the level of people who practice martial arts is divided into five realms: Bright Jin, Dark Energy, Transformation Energy, Jindan and Extreme Realm, but think about it, have you ever seen a person from the Extreme Realm?" the white-robed old man asked a key question.

"Master, aren't you just ......," Zhang Yuan was interrupted before he could finish speaking.

"So you see I'm like this now!!" the white-robed old man scolded angrily.

"Oh, you say that, I really haven't seen or heard of the legends of the powerhouses of the Extreme Realm. Zhang Yuan lowered his head and thought carefully.

"Hmph, that's because, in this world, there are some forces that we don't know about that are interfering with the entire martial arts," the white-robed old man's eyes were deep, as if he was seeing through something, "Huaxia, there are a group of hidden sects, they are interfering in the entire martial arts, forcibly pulling those who have successfully broken through to the extreme realm out of the red dust and joining their sects. ”

"Ah, that's not fair to these people. Zhang Yuan shook his head when he heard this.

"But that can protect the mortals of the land of China, these hidden sects are also committed to maintaining peace in the world, the great war of the strong in the extreme realm can destroy the world at every turn, how can these sects allow such strong people to wreak havoc in the mortal world, they will definitely send a stronger extreme realm to forcibly pull these people into the sect, Xingyi Sect, is one of them. ”

Zhang Yuan remembered what Shang Cheng said about the old immortals of the hidden world, and secretly marveled in his heart, it seems that Shang Cheng also knows the existence of these hidden sects.

"The strength of the Xingyi Sect is unimaginable, this sect can be said to be the strongest among all the hidden sects, and their ancestral treasure book is this "Unintentional Medical Codex", they will guard the root of this book that can be said to be the first inheritance book in the sect, and will not allow any outsiders to touch it!!" The words of the white-robed old man were like a slap in the face, making Zhang Yuan suddenly wake up to this medical book.

"Therefore, this Xingyi Medical Book is a double-edged sword, if used well, you can destroy all the enemies outside the Hidden World Sect, but once it is discovered by the Xingyi Sect, you will face an endless, endless pursuit and killing. The white-robed old man sighed, "So, you have to be prepared." ”

Zhang Yuan smiled and put on a cultivation posture, he looked indifferent: "Teacher, after so many years, I still believe that if you have gain, you have to pay, if you want to gain strength, you have to face risks, if you retreat, I can't even get through the difficulties in front of me, what do you want to talk about in the future?"

After that, Zhang Yuan closed his eyes, and his mind guided the majestic true qi in his body, running according to the route prescribed in the "Unintentional Medical Codex", and the true qi suddenly ran to the unfamiliar meridian line, and some resistant emotions began to be restless.

"Hiss!!" Zhang Yuan gasped, forcibly endured the pain in the meridians, and continued to guide this part of the true qi to dredge these unused meridians, and the sharp pain could not disturb Zhang Yuan's mind.

One, two, three...... There are constantly unused meridians that are dredged, but Zhang Yuan is also tortured by pain, his body is covered with sweat, and his facial expression is painful, which shows how much pain he has endured.

"Okay!!" I don't know how long it has been, Zhang Yuan finally ran all the meridians and successfully ran for a week, Zhang Yuan did not rest at this time, but struck while the iron was hot, and kept running the true qi according to the Zhou Tian route in the "Unintentional Medical Codex".

The dantian is like a spring of water, constantly sending out the stored true qi, which has been transformed into more condensed true qi after running for a week, and the whistling sound is more powerful.

After the true qi in the body of "Hu !!!" successfully ran for a week, Zhang Yuan breathed a sigh of relief, he felt in his body at this time, and felt that his strength had risen more than a bit, and even he had a feeling that when he encountered Shang Cheng again, he could defeat him within ten moves without even using various hidden weapons, in a frontal battle, and even kill him!!!

"How do you feel, how is Zhou Tian of the Unintentional Medical Codex?" the white-robed old man asked with a smile when he saw that Zhang Yuan had completed his transformation.

"It is worthy of being the first sect's medical codex, and I feel that this medical code can allow me to fight across two levels!!!" Zhang Yuan rubbed his shoulders and said confidently.

"Haha, that's good, you can start to break through to the middle stage of the Jindan Realm now, with the support of the Unintentional Medical Codex, I guess there will be no problem with your breakthrough this time. The white-robed old man stroked his beard.

"Hmm!!!" Zhang Yuan said, and immediately entered the state of cultivation, Zhang Yuan followed the feeling of the true qi impacting the dantian, adjusted the true qi out of the dantian and ran for a week, and then sent the true qi into the dantian to try to expand the volume of the dantian, after several impacts, the dantian reacted, and the true qi it contained began to gradually increase.

Because Zhang Yuan has been accumulating for a long time, and after a series of battles, even his body has been hit hard, there are already signs of an imminent breakthrough, and there are even signs of true qi spontaneously colliding with the dantian, all of which are signs that he has actually matured.

Therefore, Zhang Yuan's breakthrough was not greatly hindered, and the barrier that Dantian held on to was quickly unable to hold on, and the repeated true qi impacts quickly broke through the barrier of Dantian.

With a "boom", the true qi in Zhang Yuan's body surged, and the unimaginable true qi suddenly rushed out of the dantian, filling every corner of his body, and the stormy true qi blew Zhang Yuan's hair upward.

"This kid, this time the fortune is not shallow, this breakthrough has directly reached the peak of the middle of the Jindan period, and it is not too far from the next breakthrough, it seems that this kid will soon be able to enter the ranks of the real powerhouse. The white-robed old man smiled with relief, secretly happy in his heart for Zhang Yuan's strengthening.

"Whew!!!" Zhang Yuan exhaled a breath of turbid air, and the true qi whistling in his body also calmed down, he slowly opened his eyes, felt the strength of his whole body, and smiled proudly.

"Improved so much?" Zhang Yuan felt the explosive sense of power in his body, and was a little amazed.

"I may have not broken through for a long time, but this time I will break through a little more. The white-robed old man said with a smile.

"Okay, my breakthrough has been solved, why don't you go out and see their actions. ”

Nanyin City Government ......

"Zhang Yuan, it's here again so soon, what's going on?" The Netherworld was manipulating his hands behind his back, looking at the map of Southern Xinjiang, when he suddenly heard Zhang Yuan's footsteps outside.

"I want to say, we should be a little more high-profile, you should order all the troops, march towards Nanyang City, attack Nanyang City!!!" The corners of Zhang Yuan's mouth rose.

"Attack Nanyang?" "You didn't take the wrong medicine, don't you know what level of powerhouse Shangde is, he should have been a strong man of Jindan Dacheng a long time ago, and even the peak of Jindan is possible, you are only a beginner in Jindan, why do you keep persuading him?"

"Then what if I say that I have just broken through to the middle stage of Jindan, and I can still digest the treasure I got in the ruins, now even if that old immortal Shangde is a powerhouse at the peak of Jindan, I am not afraid of him at all. Zhang Yuan replied confidently.

"What, you just broke through?" the Netherworld looked at him in shock.

"Yes, the time has come, and it will be !!!a matter of course," Zhang Yuan said and took out two pills from the Na ring, "Two broken gold pills, for the two of you, on the condition that after the restoration of southern Xinjiang, for a period of time, you will be on my side." What kind of elixir is the Broken Gold Pill, I don't need to tell me!!!"

"You jumped in, so generous that I couldn't be more generous, so I couldn't refuse. Netherworld took the broken gold pill in Zhang Yuan's hand and grinned.

"Okay, then we'll go crazy with you in Nanjiang!!!" Netherworld slammed his fist on the table, "It's just right, I've been holding back my nausea for a long time!!!"
