That being said, in fact, Lu Tongda didn't think that Xu Xingkong could do such a thing as emptying the Yin Attribute Yuan Spirit of the entire Bagua Transformation Spirit Array, at least, he couldn't do it himself.

But if you think about it carefully, it's not impossible, what if that bastard gave Xu Xingkong some powerful spiritual weapon?

Of course, even if that situation really occurs, it's nothing, as Lu Tongda just said, if the largest number of Yuan Spirits in the formation is occasionally emptied, it can indeed accelerate the operation of the formation and play the role of dredging the nodes and channels of the formation, so this is actually a good thing, and Lu Tongda is also happy to see it.

However, when Xu Xingkong really started casting spells, Lu Tongda was still taken aback.

Xu Xingkong did not use the rapid casting of the talent spell, but used the orthodox spell casting method on the "Detailed Explanation of the Spell" in a serious way, and cast the Yuan Ling Returning Technique one by one.

But Shi Bei was impressed by the three days, Xu Xingkong is no longer a rookie who doesn't know anything, especially after experiencing the life-and-death struggle in the Thunder Sound Cave, and after repeatedly using the Compound Five Elements Enchantment Technique, Xu Xingkong has already crossed the entry stage of spell casting, and half a foot has stepped into the hall of magic mysteries.

In fact, the basis of the Yuan Ling Returning Technique is the Two Rites Theory, although the Two Instruments Theory and the Five Elements Theory are completely different theoretical systems, but there are still commonalities in them, and the comprehension of the Five Elements Enchantment Technique can also be used in the Yuan Ling Returning Technique.

In addition, Xu Xingkong's original mastery of the Yuan Ling Returning Technique was very high, and he activated the real vision during the casting process, these favorable factors were superimposed, resulting in a multiplier effect, and the efficiency of the Yuan Ling Returning Mind Technique reached an unprecedented height, and even Xu Xingkong, as the caster, was surprised by the actual casting effect.

When the effect of the spell reached a certain height, Xu Xingkong suddenly had a wonderful feeling, as if there was an inexplicable thing guiding him to cast spells in the dark, and when he subconsciously accurately embodied the details of these spells, a wonderful vision magically appeared in Xu Xingkong's mind.

"It's... Is it a resonance phenomenon? ”

Xu Xingkong looked at the Qi Qi in front of him with some surprise, he should have seen this situation for the second time, the first time was when Lin Xiaofeng sacrificed the spirit weapon Ice Spirit to cast the Extreme Yang Sword, at that time he completely entered the world of Yuan Ling, and now there is a similar situation in front of him. But this time the level of resonance is not as deep as last time, last time he completely entered the world of Yuan Ling, and this time, he is at the junction of Yuan Ling and the material world.

This experience is actually even more wonderful, when the perception completely enters the Yuan Ling world, the material world is only a few dotted and line structures in Xu Xingkong's perception, and when at the junction of the two worlds, Xu Xingkong perceives the material world and the Yuan Ling world at the same time, the two are like two transparent worlds that are soaked and overlapped with each other, in this case, Xu Xingkong can even directly observe the buildings above the surface of the earth in detail.

It's a wonderful feeling, and it's exhilarating at the same time, not the excitement of being able to see the secrets hidden under the beautiful woman's clothes, of course, but the excitement of having nothing in front of you that can block your view, a feeling of completely breaking free from all the shackles imposed by the world, and from then on the whole body and mind are freed from the shackles and have gained complete freedom.

At this moment, Xu Xingkong is like a free soaring in the endless sky, overlooking the clouds rising and disappearing, looking at the vicissitudes of the sea, it seems that every secret of the world is fully displayed in front of him, and at that moment, Xu Xingkong even feels that he is a god, the omniscient and all-powerful master of the entire primordial spirit and the material world.

It's so poisonous that it's terrifying!

Xu Xingkong was only addicted for a moment, and immediately woke up from this trance-like state, after all, he almost made a big deal last time, which made him almost lose such an important partner as Lin Xiaofeng, so he subconsciously had a strong sense of resistance to anything that made people addicted.

The subconscious mind itself is definitely the most important part of the practitioner, and it is also the potential warehouse and insurance facility of the practitioner, and even on a certain process, it can be said that the subconscious mind is more important than the manifest consciousness, and it also has a stronger ability to protect itself.

Xu Xingkong, who came to his senses, glanced at the surrounding situation, and was quickly attracted by the interaction between his Yuan Spirit Returning Technique and the surrounding Bagua Spirit Array, and he immediately realized that the wonderful induction that appeared when he cast the spell just now should have come from this Bagua Spirit Array?

In fact, it is not difficult to understand at all, Xu Xingkong's casting in the core of the Bagua Spirit Array's Kun position is essentially a problem of nesting formations, and it is impossible to ignore the influence of the Bagua Spirit Array while performing the Yuan Ling Returning Technique, and in turn, the Yuan Ling Returning Technique will inevitably affect the operation of the Bagua Spirit Array.

It is precisely because of the intrinsic and inevitable connection between the two that when Xu Xingkong performed a high-level spell just now, he would vaguely feel the subtle influence from the Bagua Spirit Array, and when he adjusted the details of the spell casting in accordance with this influence, he successfully made the two formations (spells) form the best resonance effect, and by the way, Xu Xingkong's true vision was brought into this resonance effect, so that Xu Xingkong once again witnessed the resonance of the human array.

In the book "Detailed Explanation of Spells", it is also mentioned that the resonance of the human array and the resonance of spell casting, when the resonance occurs, the primordial spirit of the caster or the main array will resonate with the primordial spirit mobilized by the spell, and obtain the transcendent perception with the help of the primordial spirit. After experiencing it twice, Xu Xingkong really felt that the resonance of this spell was indeed a good thing, but it was not easy to achieve resonance.

In fact, through the resonance of the formation and the spell, Xu Xingkong not only gained the transcendent perception, but more importantly, he gained the opportunity to have an in-depth understanding of the formation and spells, this intuitive and subtle experience process is extremely precious, and people who have not experienced it do not know what huge benefits this will bring to the caster, even Xu Xingkong, who has real vision and can directly watch the interaction between the Yuan Spirit and the spell, also feels deeply beneficial.

Not to mention that Xu Xingkong was happily immersed in the in-depth comprehension of the formation and spells, and Lu Tongda, who was watching from a distance, was completely stunned by what he saw in front of him.

Although he does not have the same powerful real visual ability as Xu Xingkong, as a cultivator who has been immersed in the field of perception research for many years, perceiving the Yuan Spirit and knowing the world through the Guò Yuan Inspiration is the goal he has always pursued, so he is still very confident in perception.

However, what happened in front of him made Lu Tongda involuntarily doubt his perception ability and results, he really couldn't let himself believe that Xu Xingkong's extremely standard Yuan Spirit Returning Technique could gather such a scale of Yin Attribute Yuan Spirits, and he didn't want to believe that the Bagua Spirit Array he was extremely familiar with was running at an unprecedented speed.

What made him even more unacceptable was that as the guardian of this hospital, as the host of this huge Bagua Transformation Spirit Array, it was absolutely impossible for him to drive the formation to such a distance, this kind of efficiency made Lu Tongda unbelievable, and the reason for this result made him unable to explain, and at the same time, there was a deep sense of frustration and resistance, constantly impacting his powerless heart.

On the other hand, he couldn't help but be a little worried in his heart, for fear that this situation would develop further, and even develop to a situation where the formation was out of control. In fact, this is not completely impossible, if the operation speed of the Bagua Transformation Spirit Array is further accelerated, it is possible to reverse the energy originally transmitted to the City Returning Yuan Array, and instead draw energy from the City Returning Yuan Array, which will eventually lead to disastrous consequences.

But stopping Xu Xingkong at this time made Lu Tongda feel very shameless, after all, he had just said that there was no need to restrict the use of Cheng dù, and although Lu Tongda didn't want to admit it, he also had a little hope that the accident could really happen.

Just when Lu Tongda hesitated, the crazy operation of the Bagua Transformation Spirit Array actually stabilized, but the operation and change of the Bagua Transformation Spirit Array did not stop there, but this change began to develop from the improvement of quantity and speed to the improvement of quality, and the efficiency of energy conversion and purification in the formation continued but slowly improved.

This qiē change made Lu Tongda dumbfounded, the whole person was wooden, his brain seemed to be unable to think, he had an urge to immediately find a puddle to drown himself, looking at Xu Xingkong's young face, Lu Tongda felt that his age was completely alive to a dog.

．．．．．．

It was almost twelve o'clock when he returned home, and he drove Lu Weidong, who was still playing mobile games, to sleep, Xu Xingkong washed up casually, and studied the slightly changed demon book for a while according to the usual practice, and then lay on the bed after reading a few pages of "Detailed Explanation of Spells".

Subconsciously perceiving the situation upstairs, and found that Lin Xiaofeng still hadn't gone home, and was a little inexplicably worried, but if you think about it carefully, Lin Xiaofeng is Yang Wanjiang's beloved apprentice, and she knows how much Yang Wanjiang spoils her by looking at the endless high-end spiritual weapons in her hand, so she will definitely not have any problems, and her worries should be purely superfluous

Letting go of his thoughts, Xu Xingkong looked at the Xuan Ling Zhu, which had almost completely turned dark green, and closed his eyes with an expectant smile on the corner of his mouth.

I don't know how long I slept, Xu Xingkong was suddenly awakened by an inexplicable palpitation.

After sobering up a little, Xu Xingkong immediately put his mind into the Xuanling bead hanging around his neck in surprise.

Entering the space of Xuanling Bead, a beautiful figure with a bump immediately came into Xu Xingkong's mind, and he immediately turned his head away, not daring to look at this naked ** again.

seemed to feel Xu Xingkong's arrival, Xiaolu, who was originally confused and confused, and even a little scared and anxious, immediately turned his head, and then ran towards Xu Xingkong's side in surprise.

"Xu, Xu Xingkong? Yes, is that you? (To be continued.) )
