The chill in Cao Yanyue's body is getting stronger and stronger, and this chill is not the cold of the temperature, but also a kind of fierce cold from the depths of the soul.

A red light suddenly erupted on the Xuantian Mirror, marking more than ten blockages in the meridians, as well as more than twenty True Qi routes that were on the verge of collapse.

"Ye Ling's sixteenth body, is it actually not suitable for the Yin Spirit Root?"

Cao Yanyue made a decision immediately, but he didn't have time to disassemble it, and with a flick of his thumb, Taiyi Tiangang's sword qi shot out, shattering another talisman real person, grabbing out the pure yang spirit root, and sticking it on the back spine.

The distorted bone spurs of the spine seemed to have found an outlet, piercing this pure yang spirit root, and under the intersection of yin and yang, the distortion was finally directed to the right path.

The spine changed one by one, turning into red and black, and the bone spurs slowly contracted back, and the Nine Heavens Refining True Qi penetrated through this spine, turning into a rising dragon, like a phoenix in the nine skies, rushing into the top of the brain.

Cao Yanyue heard a crisp sound like popping beans from his spine, which continued endlessly, and the sound was hundreds of times, and finally the door of his head was like being slashed by an axe, the gate of heaven exploded, and the distortion of the spiritual root was finally completed.

Cao Yanyue was sweating like pulp, and a layer of greasy fat was discharged from his body, he stood up and found that he was one or two centimeters taller, and his whole body was also much lighter, and the connection with the vitality between heaven and earth was even more subtle.

Moreover, what surprised him the most was that in addition to the Brahma particles, there were also two kinds of Yuan Qi particles, which surrounded him and corresponded.

There is no need to detect it, Cao Yanyue can sense it purely based on experience, and these two kinds of vitality particles must be polar yang particles and polar yin particles.

The pure yin and yang spirit root naturally fit these two kinds of vitality particles.

Polar Yang Particles and Polar Yin Particles, a single one, cannot be used at all, but the two Yuan Qi particles can be refined according to a certain ratio, but they can practice ever-changing mana.

In terms of the research of these two kinds of vitality particles, Zhuxia was originally a little behind foreign countries, but decades ago, Tenzenji University made a breakthrough in the research of these two kinds of vitality particles, and jumped into the forefront of the world, and quickly became far ahead.

Kunlun's research on the two kinds of Yuan Qi particles is slightly behind Tianchanji University, but it is also quite successful.

The seventy-two thaumaturgy of the Kunlun Sword Immortal Academy, second only to the Nine Heavens Alchemy Technique's "Theory of Heaven and Earth Yuan Qi", is the top-level mental method for cultivating extreme anode yin particles.

The Theory of Heaven and Earth Yuan Qi was originally very famous, and it was a martial art hundreds of years ago, and it can be said that it was this martial art that opened the prosperous era of martial arts in Zhuxia.

This martial arts scripture expounds the mystery of the vitality of heaven and earth, Kunlun has always been known as the mystery of martial arts in the world, all in this scripture, based on the theory of the vitality of heaven and earth, the martial arts of the world, can be driven.

This martial art is closer to a theory, and if you really learn it, because it is too broad and profound, it is not easy to achieve achievements, so it is ranked below the Nine Heavens Alchemy.

Later, the martial arts society declined, the immortal society flourished, and the theory of heaven and earth vitality also fell lonely.

Although it has been repeatedly deduced by several generations of teachers and students of Kunlun Sword Immortal Academy, and even accommodated more new theories, its reputation has never been as good as Tianchansi University's "Mana Refining Chapter".

Cao Yanyue tried to operate the Heaven and Earth Yuan Qi Theory, and sure enough, the extreme yang particles and extreme yin particles that were ubiquitous in heaven and earth combined into mysterious mana, which continued to converge into his mind.

In just a few hours, he had already condensed a shallow layer of mana.

Cao Yanyue whistled, stepped into the bathroom, took a hot bath, and waited until he changed into a new swordsman suit, and the whole person was in good spirits.

This time of cultivation, Cao Yanyue has opened up the three meridians, the eight veins of the Qi Sutra have all been penetrated, and only five of the twelve canons have not yet been opened, and it is not far from the completion of the first layer of the mental method.

He sat cross-legged on the ground, opened a can of energy drink, and threw the civet cat on the wireless platform of the real qi charge, not thinking about the daytime at all, but thinking about it, the matter of the young sword immortal equation.

At that moment, a communication came.

Cao Yanyue glanced at it, it was Qi Tang, and then he remembered that he had made an appointment with Qi Tang and Gongsun Yue to fight a simulated battle in the Ten Thousand Realms Spirit Domain.

Last time, he brought Chi Yuehan and Liu Li, and they fought a game, and they won a miserable victory, and the process was very difficult.

Qi Tang said angrily: "Young Master Cao, you just change your name, you don't need to release pigeons to celebrate, right?" ”

"Xiaoyue called you dozens of them, and I also called seven or eight, but I just couldn't get through."

"If it weren't for Xiaoyue to say it, what happened to you today, Miss Ben is very sympathetic to you, and she will definitely drag you to the bottom at this time and break off your friendship for life."

Cao Yan was a little embarrassed, and said: "It's a little depressed, I want to be quiet for a while after closing the Ten Thousand Realms Spirit Domain, and say sorry to Xiaoyue for me." ”

Qi Tang said: "You said it yourself, she was so worried." ”

Cao Yanyue said: "Ten minutes, I'll come up, you wait a little longer." ”

Qi Tang listened to Gongsun Yue during the day, and when she talked about what happened today, she was not much angry, she was asked by Cao Yan to release the pigeon, she was a little angry, because Gongsun Yue was worried and grinded her for several hours, and Qi Tang was about to be tortured and crazy.

Qi Tang turned off the communication, and they had already arrived at the simulated battlefield of the Ten Thousand Realms Spirit Domain, this illusory battlefield was an endless plain, and there were countless abrupt peaks on the plain, rising from the ground, which was the most suitable place for sword cultivation and sword fighting.

Gongsun Yue looked worried and asked, "Is he okay?" ”

"I shouldn't have waited here, I should have gone to him."

Qi Tang said angrily: "This bastard is fine, he just closed the Ten Thousand Realms Spirit Domain and wanted to be quiet." ”

After a slight pause, Qi Tang said: "A boy who lacks love, once it is done, I heard that it will be very abrasive." ”

"Xiaoyue, can you stand it?"

Gongsun Yue's face turned red and said in a low voice, "Don't be so sassy." ”

Qi Tang sneered and said, "I don't know who is complaining." ”

The three teenagers on the opposite side waited for a long time, although they were impatient, but they were in the same space as the two beautiful girls, and they were pleasing to the eye, and they didn't lose their temper.

One of them said to his companions: "Xu Zhenyang, can you come to their contact information?" ”

"The simulated battlefield is a random match, and the other party is anonymous, and I asked for a friend just now, but I was denied."

"These two girls are high-end goods in the imperial capital, one in a thousand."

Xu Zhenyang's face was gloomy, and he didn't want to do this kind of thing, but he was relatively weak in the team, so he could only send a message to Qi Tang and Gongsun Yue: "My two teammates are from the imperial capital, Wang Xiao is a four-star high school student, Li Linan is a three-star high school student, and their strength is above me." They want to get to know you, can you get to know them through their friends? ”

Qi Tang and Gongsun Yue didn't pay attention to Xu Zhenyang.

The name of the No. 1 high school student in Boyang City is not easy for them here.

Wang Xiao saw Qi Tang and Gongsun Yue, and didn't reply to the message for a long time, and his anger gradually grew, and said, "Don't keep your hands later, let them know that the tenth-level Taoist disciples are nothing." ”
