In order to avoid a conflict between the knowledge that was integrated into the mind and his own memory, the Fa sealed most of the knowledge that he could not use now, leaving only a small part of what he could understand as a reference. And after he completely gave up the idea of resistance, he also lifted the spirit treasure and magic circle that defended against the primordial gods, and at the same time untied the physical and mental shackles. This unintentional behavior led him to a rare state of enlightenment. Feeling that such an opportunity was rare, he took advantage of this momentum and did not hesitate to deduce the Heaven and Earth Human Mirror and the True Martial Destruction Sword Technique in the realm of the Dao Heart.

Due to the fact that there is a lot of knowledge related to the heaven, earth and man mirror as a basis, Xu Changqing's understanding of the heaven, earth and man mirror has also improved a lot in a short period of time. Later, he deduced more than ten techniques suitable for him from the three control techniques of the heaven, earth and man mirror that he could use, and further improved the control techniques suitable for himself.

also knew whether the other party did it deliberately, and the knowledge of the heaven, earth and human mirror that was passed on to him also contained a lot of content related to the Taiqing Liangyi Dust Array.

In the realm of Dao Heart, Xu Changqing further fused this knowledge and deduced the Taiqing Liangyi Dust Array, and found that some of the Taiqing Liangyi Dust Array formation techniques that he had comprehended from the reincarnation pool were completely full of mistakes and omissions. Although these techniques can be regarded as infinitely powerful against ordinary level immortals, compared to the real Taiqing Liangyi Dust Array, these techniques are not even close to the surface of the formation. Among them, there is a reason for the incomplete reincarnation poolside formation, which may also be related to his own lack of cultivation and inability to perceive the higher level of this ancient formation. In a word, if he followed the method he had comprehended and deduced before, and used the Ten Thousand Ghosts Spirit Attraction Great Array to break the formation next to the reincarnation pool, the final result was very likely to be fruitless.

From this knowledge, Xu Changqing learned that the real Taiqing Liangyi Dust Array was divided into nine layers, and there were more than a thousand kinds of Gu Immortal Arrays, and even the most basic and simple first layer had more than 20 formations. Although he now mastered a more detailed and correct knowledge of the Gu Immortal Array, what he could absorb was only a small part of the foundation, and with his own cultivation, he couldn't even fully deduce the first-layer formation technique. If you want to completely absorb and integrate this knowledge, the time required will be at least 10,000 years, and your cultivation will also need to reach the level of the Great Awakening Golden Immortal. Even so, it was only to absorb and integrate this knowledge, and it was still far from fully mastering this Ancient Immortal Array. At the same time, he also understood that the Gu Immortals who were able to use the Taiqing Ancient Immortal Array recorded in the ancient books of the cultivation world actually only knew some superficial knowledge, and they were not even as good as him now.

While lamenting the profundity of the Taiqing Ancient Immortal Array, Changqing couldn't help but revere the Zhenwu Emperor who could fully master the Taiqing Liangyi Dust Array. Although Xu Changqing was also quite proud of his intelligence, he was not arrogant enough that he could compare to those Gu Immortals who had been endless for years, and he did not have the luxury of being able to master most of the Ancient Formation Formation Techniques in a short period of time. In the end, he found another way, integrating the formation technique and Gu Immortal Array that he had deduced and mastered into the formation technique he had comprehended before, further perfecting his own Taiqing Liangyi Dust Array, and using it to repair the Destruction Sword Technique.

Because there was so much knowledge to comprehend, it took Xu Changqing a long time to sort out all the knowledge in the Dao Heart realm, and it took a lot of time to integrate a small part of the knowledge. Although in the realm of Dao Mind these times there are thousands of years, in the outside world these times are only a few days. After Xu Changqing's mind submerged into the Dao Mind Realm, Xu Daoling, who was sitting opposite, did not show any dissatisfaction or impatience at all, smiled and nodded approvingly like a teacher, and then sat quietly waiting for Xu Changqing to come out of the Dao Mind Realm.

In the Dao Heart Realm, Xu Changqing unleashed the True Martial Destruction Sword Technique that had been modified and deduced from the seventeenth time, and a piece of the sky and stars that he had conjured up from his mind were shrouded in ten thousand sword lights, and instantly turned into nothingness. Although he had already prepared in his heart, he couldn't help but feel shocked by the power of the sword technique after it was fully displayed, and at the same time, he also longed for the true true martial arts to destroy the great sword power of the heavens. Although the True Martial Destruction Sword Technique that was deduced and modified by him already possessed the great power of destroying the heavens and the earth among the ancient immortals, this was only the result of deducing it in the Dao Heart Realm, and if it was in reality, I was afraid that it would be difficult to perform a complete sword technique with his cultivation. So he divided the entire sword technique into three styles according to the way of heaven, earth and human mirror, among which all those who can be freely displayed by his current cultivation are classified as human styles, and the rest that cannot be used are attributed to the earth style, and as for the heavenly style, it is completely a complete true martial arts in the illusion of destroying the great sword power of the heavens.

After sorting out all the knowledge, Xu Changqing's deduction to the Dao Heart Realm had reached the limit of his Dao cultivation, so his mind broke away from the Dao Heart Realm and returned to reality. After getting out of the Dao Heart Realm, although Xu Changqing's Yuan Shen was slightly tired because of the excessive consumption of his mind, his temperament had changed, and he was closer to the ethereal realm of the Dao Spirit, and Xu Daoling, who was on the other side, also nodded with satisfaction.

At this time, Xu Daoling pointed to the cup of tea in front of Xu Qing and said, "You should be able to drink this cup of tea with confidence now, right?"

Xu Changqing looked at it, hesitated a little, and finally picked up the teacup and drank it all. After drinking this cup of tea, he immediately felt a warm heat spread throughout the Yuan Shen, and the previous consumption was immediately replenished, and the Yuan Shen realm also improved rapidly, faintly approaching the spirit god realm of the legendary ancient golden immortal. It's just that between the two realms, there seems to be a thin film barrier, so that the primordial spirit is always on the verge of advancing and retreating.

While Xu Changqing was feeling the improvement of the Yuan Shen with all his heart, Xu Daoling on the opposite side also showed a trace of surprise on his face, as if he was surprised that Xu Changqing's Yuan Shen was able to exert the effect of this cup of tea to such an extent. Then he seemed to be talking to himself, and said slowly: "The so-called thousands of laws are not as good as your own local laws! There is no distinction between high and low laws, and those who have high and low are the people who cast the spells. At that time, the ancestors of the Nine Streams and One Lineage were only half cultivators, but they were able to create their own Dao mind realm, and use this to deduce various Dao methods and Buddhism. Its effect can be described as unparalleled in the world, and even the immortal law of the ancient immortal realm cannot be compared with it, so it is better to learn the law than to understand the law, and it is better to understand the law than to understand one's own law. ”

Although Xu Daoling's words were an understatement, when he heard Xu Changqing's ears, it was no less than thunder, and the fog on his mind immediately dissipated, and the obstacles that blocked the progress of the Yuan Shen disappeared, and he entered the Spirit God realm in one fell swoop. As Xu Changqing's primordial spirit turned into a golden immortal spirit god, a cloud of immortal mist poured out of his body, and the strange snake wrapped around his body and the two giant turtles under his feet also swept away the previous dead qi and became vivid. The eight-treasure glazed ginseng fruit tree behind his head has changed even more, not only growing radiant colorful leaves, but also growing a vast ginseng fruit between the branches and leaves.
