In the past seven days, Gao Xuan has learned a lot of things in the classroom, such as cultivation methods, fighting skills, and the use of occult techniques, and most importantly, Gao Xuan feels that these things are very useful.

Gao Xuan had been pondering the method of reverse cultivation before, but he finally found that reverse cultivation did not seem to be suitable for him, because he had never touched the threshold of reverse cultivation, on the contrary, after learning some cultivation methods in class, he found that the speed of absorbing the aura of heaven and earth became faster in the application.

In addition to learning a lot of knowledge in the classroom, the preparation of Yafeng Pavilion is also progressing steadily.

Four days ago, Qi Xing and Gu Xiaoxiao sent the materials needed to build the carrier bracelet to Tao Jingye, and the carrier bracelet was officially put into production, and so far, the production of the carrier bracelet has reached one-third of the total output of the first batch.

Gao Xuan and Xu Sanjin have already discussed, after the end of the centralized teaching, they will first take out part of the communication bracelet, first promote it in Linghui Division, give it to Shang Muying and other Linghui Division bosses for free, and the other part will be discounted in Linghui Division, and first make the communication bracelet famous in Linghui Division, but that will be after tomorrow, because today Gao Xuan wants to try to break through.

Seven days ago, Gao Xuan realized that he was going to break through, but Gao Xuan always felt that the opportunity for a breakthrough was not mature enough, so he pushed it to the present.

At the end of today's intensive teaching, Gao Xuan pushed away everything and returned directly to the school, ready to break through, with the experience of the last breakthrough, Gao Xuan relaxed a lot this time to break through, not as nervous as last time.

With the Shura Divine Technique running at full strength, Gao Xuan began to seriously feel the operation law of the rank barrier.

Now outside Gao Xuanjing's Xuanjing, there are not only rank barriers, but also the seal left by the old man Gao and the chaotic qi given by the seal of life and death, Gao Xuan didn't feel the impact of the seal left by the old man Gao on himself, nor did he feel that the chaotic qi helped him, but the two really existed around the Xuanjing.

Until now, Gao Xuan didn't understand what the chaotic qi was, and he didn't even know the chaotic world that the two yi seals of life and death said, what Gao Xuan felt the most was the law of time and space brought by the two seals of life and death, after all, the law of time and space is the only reliance on the realization of the function of the communication bracelet, if there is no law of time and space, the communication bracelet is just an ordinary bracelet.

However, Gao Xuan did not think about these things anymore, but devoted himself to the exploration of the barrier cycle.

Now, the total number of Xuan Qi molecules in Gao Xuanjing's Xuan Jing has reached 670,000, and under Gao Xuan's control, 670,000 Xuan Qi molecules are constantly colliding with the level barrier outside the Xuan Jing.

Gao Xuan originally thought that this breakthrough would go smoothly, after all, this breakthrough was more experienced than the last time, but the result was the opposite, Gao Xuan had entered the meditation state for almost two hours, but he still failed to fully grasp the operation law of the barrier cycle.

Last time, Gao Xuan didn't take much time to successfully break through, but this time he deliberately prepared for seven days, but the result was not ideal, which made Gao Xuan a little anxious.

Gao Xuan didn't pay attention, when he controlled the Xuan Qi molecules to hit the level barrier, the chaotic qi outside the Xuan Jing also underwent some subtle changes.

The chaotic qi is a pure white gas, and its existence makes Gao Xuanjing's Xuanjing seem to be in a cloud of fog, and outsiders can't break through the chaotic qi to investigate the world inside Gao Xuanjing.

Originally, the chaotic qi was very loose around the Xuanjing, but now, the chaotic qi gradually converged and became more condensed, but this change was so small that Gao Xuan, who was fully controlling the Xuanqi molecules to impact the level barrier, did not notice it.

Gao Xuan could feel that the level barrier at this moment was tougher and thicker than when he first broke through the second level of the Tianyan Realm, but Gao Xuan was not afraid, because he believed that he could break through.

On the way of cultivation, it is taboo to be ambitious, and it is also taboo to be arrogant, the former makes people blind and arrogant, and the foundation is unstable, and the latter makes people unstrong and stagnant.

The so-called Dao heart is the determination of the cultivator to continue to explore the path, if the Dao heart is not strong, he loses confidence in himself, and the final result is obvious.

Gao Xuan was not ambitious, blind and arrogant, because since he condensed the Nine Rank Xuanjing, Old Man Gao warned him not to be proud and complacent because he had the Nine Rank Xuanjing, Gao Xuan was not arrogant and weak, because he knew that Han Wei was still waiting for him to save him.

At first, Gao Xuan was still a little impatient, but as time went by, Gao Xuan began to calm down, distracted, and concentrated.

Under this transformation, Gao Xuan found that his perception ability had increased a lot, and his perception of the level barrier became clearer, which also made Gao Xuan understand a truth, no matter how anxious he was, he had to calm down first, and being anxious would not solve things.

I don't know how long it took, a smile suddenly appeared on Gao Xuan's face with his eyes closed, because at this moment, he finally understood all the changes in the level barrier, as long as he grasped the opportunity and bombarded with all his strength at the moment when the level barrier turned from the strongest to the weakest, he could shatter the level barrier.

After discovering the law of change of the level barrier, Gao Xuan did not hesitate any longer, the Shura Divine Technique was running with all his strength, and the Xuan Qi molecules tried their best to crash towards the level barrier in this short moment.

Rumble!

The Xuan Qi molecule collided with the rank barrier and made a huge roar, but this time, the rank barrier did not break because Gao Xuan did not grasp the opportunity.

Gao Xuan didn't give up, and guided the Xuan Qi molecules to hit away again, it may be that Gao Xuan had just mastered the law of change in the barrier cycle and failed to grasp the opportunity, and this time the level barrier was still not broken.

Knock knock!

Gao Xuan adjusted his state again, and this time, Gao Xuan could clearly hear the sound of his heartbeat, which also showed that Gao Xuan's state was close to saturation.

This time, Gao Xuan was not in a hurry, he once again investigated the law of change of the level barrier.

After a few breaths, Gao Xuan's body was completely relaxed, his mind was highly concentrated, and he controlled the Xuan Qi molecules to attack the level barrier for the third time.

Rumble!!!

This time, Gao Xuan didn't miss the opportunity, his attack was just right, and the rank barrier was shattered under the attack of the Xuan Qi molecules.

At this moment, the Xuan Qi molecules who had lost the shackles of the rank barrier were frantically splitting, and the number of Xuan Qi molecules was growing at an alarming rate.

It's just that Gao Xuan can feel that the level barrier that he had just shattered began to condense again, the number of Xuan Qi molecules was growing, and the fragments of the level barrier were slowly condensing, and as the level barrier condensed again, the splitting speed of the Xuan Qi molecules became sluggish.

After a few breaths, the rank barrier condensed and formed again, but there were still clearly visible cracks on the level barrier, and at this time, the Xuan Qi molecules almost stopped splitting.

After a breath, the crack of the level barrier completely disappeared, the Xuan Qi molecules also stopped splitting, and Gao Xuan, who had been meditating for several hours, also opened his eyes in an instant.

In this brief moment, the Xuan Qi molecules around Gao Xuan's body expanded rapidly, and then, the expanded Xuan Qi molecules quickly contracted, returning to Gao Xuanjing, Gao Xuan checked the number of Xuan Qi molecules in the Xuanjing, and showed a satisfied smile.

Now, the total amount of Xuan Qi molecules in Gao Xuan's body has reached 940,000, including 40,000 green Xuan Qi and 450,000 red and black Xuan Qi each.

After Gao Xuan woke up, he found that it was already dawn, and Gao Xuan did not continue to meditate, because according to the agreement, he was going to promote the communication bracelet with Xu Sanjin today.

Soon, Gao Xuan found Xu Sanjin, and the two chatted for a while, and then swept in the direction of Tianshui City.

This time, Xu Sanjin didn't bring Qi Xing and Gu Xiaoxiao, because today was the day when Lingkui Si concentrated on teaching, and the two of them couldn't take a break.

It didn't take long for Gao Xuan and Xu Sanjin to come to a very familiar place, the Tianshui City Refiner Association.

Tao Jingye is an instrument master, a disciple of the Lingyuan Academy, and a registered member of the Refiner Association, and since Tao Jingye became an appraiser, he has spent much more time in the Refiner Association than in the Lingyuan Academy, and the place where the carrier bracelet is produced is also in the Refiner Association.

Gao Xuan once questioned this, but Tao Jingye insisted on producing in the Refiner Association, because Tao Jingye said that the facilities in the Refiner Association would be more complete and the production efficiency would be improved, and under Xu Sanjin's persuasion, Gao Xuan finally agreed to this.

If the assembly of the carrier bracelet was also in the Refiner Association, Gao Xuan would definitely refuse, because he didn't want to expose the matter of the seal of life and death.

Although Gao Xuan didn't know what the Seal of Life and Death was, Gao Xuan could feel that the Seal of Life and Death was not simple, otherwise, Old Man Gao would not have told him about the Seal of Life and Death for so many years.

This time when he came to the Refiner Association, Gao Xuan was not as confused as he was when he first came, and the two quickly found the receptionist.

This time, the reception staff was not a man, but a woman, and Gao Xuan found that this woman was quite delicate.

With the help of the woman, Gao Xuan and Xu Sanjin successfully found Tao Jingye, and took away the carrier bracelet that had been produced from Tao Jingye.

After getting the carrier bracelet, the two returned to Lingyuan Academy, because the current bracelet is just an ordinary bracelet, and it must be activated by Gao Xuan to become a communication bracelet.

In Gao Xuan's schoolhouse, Xu Sanjin looked at the bracelets piled up all over the ground, and his heart was surprised again and again, because he saw that Gao Xuan activated a large number of carrier bracelets with every breath.

There are currently five carrier bracelets, according to Xu Sanjin's plan, the total amount of the first batch of carrier bracelets is 200,000, and now, the two of them have got a third, that is, nearly 70,000 carrier bracelets, although the volume of the carrier bracelet is not large, but 70,000 bracelets are piled together, and the scene is still quite shocking.

It took Gao Xuan almost a quarter of an hour to fully activate the 70,000 carrier bracelets, such a speed is already against the sky, you know, it took Tao Jingye a team three days to create 70,000 carrier bracelets, and Gao Xuan only spent a quarter of an hour to activate the 70,000 carrier bracelets.

When Gao Xuan activated all the carrier bracelets, he and Xu Sanjin began to implement their publicity and promotion plan.
