When Qin returned to Xiaogu Mountain, Ning Ming was busy setting up a formation at the foot of the mountain with more than a dozen foundation building monks.

The four sets of interlocking arrays are nearing completion, and only a few sporadic details need to be completed.

Qin Chong had only told Ning Ming about the possible ambush before, and had not yet told him about the underground array, so after Ning Ming saw Qin Chong, he greeted him with an expectant face.

Qin Chong could only briefly tell Ning Ming what had happened, and when Ning Ming heard that he had already dealt with the demon wolf, he was naturally overjoyed. Qin Chong secretly smiled bitterly, thought for a while, and still summoned Ning Ming into the main hall of deliberations alone.

Everyone had no way of knowing the content of the conversation between the two, only that after Ning Ming walked out of the building with a gloomy face, he directly announced that the central position of the Great Array would be taken over by Qin Zhong from today onwards.

After the two talked, Qin Chong directly stayed in the council hall for the time being, just because this was where the cardinal core of the four great arrays was located.

Qin important was familiar with the linkage of these four great arrays in the shortest possible time.

Through the exchange of information with the old wolf, after analysis, Qin Chong was able to determine that the enemy would not make a move at this time, but would only do it at the same time when the Wuji Sect, the Futu Palace, the Dragon Elephant Gate, and the Shangqing Sect launched a general attack.

Or it will be a little later, when the front line is lost, it will not only be launched in one fell swoop, at that time, it will not only severely damage the heart of the Xuantian army, but also can attack from several sides, and all the monks on this front line can be surrounded and annihilated here, that is the most favorable moment to kill and injure the enemy's vital force.

So after Qin Chong's estimation, he still has a lot of time now.

At this moment, under the guidance of the sword spirit, he is rearranging a set of control methods.

"The way of the formation is also like the circulation of the spiritual element in the human body, like the meridians and qi veins of the person, and the spiritual element is a system of its own. The key to controlling this array is not the cultivation of the person who is manipulating this array, but the understanding and induction of the Heaven and Earth Spirit Yuan!"

The sword spirit spoke eloquently at this moment:

"For countless years, the world has changed over time, and some of the formations I have mastered are completely unsuitable for the current status quo of the Ten Thousand Worlds, because the Heavenly Dao is constantly changing, and the Heavenly Dao Law there is completely different from the present. ”

Don't think that all ancient things are good, all things can only maintain their vitality by keeping pace with the times, so there is Taoism, and inheriting these things is to let future generations carry forward and innovate the knowledge system from generation to generation, rather than sticking to the rules, and the things that remain unchanged will eventually become old and outdated products.

This is the reason why so many famous treasure exercises in ancient times were finally annihilated in history and finally turned into dust, and only a few of them can be handed down, such as the Heavenly Dao Exercises such as "Dingyun Divine Fist", because they themselves are connected to the constantly evolving Heavenly Dao.

However, the heavens and the earth are changing, and there are still some things that remain unchanged, that is, the rules and laws of the Tao, as long as the laws are mastered, then no matter how ever-changing, it is inevitable to follow the laws of heaven and earth, which is why people practice the goal, that is, to master their own Tao.

As an innate soul of the sword spirit, he naturally has an incomparably deep understanding of the changes in the Heavenly Dao. Under her guidance, Qin Chong asked himself about his understanding of these four great arrays at this moment, even if Senior Brother Ning Li was here, no one could stand out.

After two days and two nights of control, it was enough for him to control these four great arrays like his fingers, which was related to the overall situation, so even if Zhenyuan was consumed for two days and two nights at this moment, Rao is background was far beyond ordinary people, and fine beads of sweat like mortals appeared all over his body.

However, even so, it can be regarded as only completing the understanding and familiarity of the old formation

The next thing to do is the most important thing.

Qin Chong took a few pills into his mouth, rejected the inside and outside, and soon entered the concentration, this consumption is really more huge than the consumption of the consecutive battles, since Qin Chong's inner heaven and earth were formed, it is the first time.

It took four hours for the body to return to its peak state.

"Qing'er, you can start, where should I start to change this array?"

With Qing'er's formation accomplishments, it is necessary to change these four large arrays into a large array composed of four sub-arrays, that is, the array within the array, and there must be no traces on the surface.

Although this formation is not a profound knowledge, even the Xuantian Foundation Cultivator on this small lonely mountain can also achieve the effect of superimposing some small arrays.

However, the change of this mountain protection array is to involve the whole body, and if you are not careful, not only is it not as powerful as not changing, but it is more likely to cause the large array to restrain each other and cause chaos in the leylines.

Moreover, there is another difficulty in the superposition of this formation, that is, every time it is superimposed, its difficulty is doubled, and Senior Brother Ning Li, who is the most proficient in the formation in the sect, is just a superposition of the three ordinary large formations in one place.

It seems that a modification of the scale of the mountain protection array, or the integration of the four arrays, may not be able to say that no one in the entire Xuantian will be able to do it.

Therefore, Qin Chong also asked anxiously in his heart: "Qing'er, are you really sure?"

When Qing'er heard this, as if she had heard the funniest thing, she covered her mouth and laughed for at least a moment before stopping, and said disdainfully:

"The frog at the bottom of the real well, my father once combined the ten thousand arrays and wiped out all the immortals of the Twelve Luo Heavens in one net, these four small formations are just that, what are you nervous about?"

"Wipe out all the immortals of the Twelve Heavens in one net?!" Qin Chong's eyes widened, even his own imagination could not imagine what a vast and vast war scene it was.

However, the sword spirit just smiled brightly, and did not touch on those past events, and began to give instructions with all his heart.

It took another five days, and under the guidance of the sword spirit, the large array called "Yin and Yang Shun and Reverse Four Elephant Great Array" in the mouth of the sword spirit was formed.

Although it has only changed more than 30 places, it is so exhausted that Qin Zhong's heart is exhausted, and he almost collapsed, all because of the large calculation in it, it is really not something that ordinary people can do, all because the leylines have been determined, and they cannot be easily changed, but it cannot be changed, but it is not impossible to accumulate as much leyline element power as possible in this array, with the power of yin and yang. Of the more than 30 sites, 24 of them have all been converted into energy storage nodes.

Thinking that the father of the sword spirit wiped out the immortals in the world in a burst that day, what kind of courage and means was it, I am afraid that it will drain the Yuan power of dozens of realms.

Although he was mentally exhausted, Qin Chong was still holding on to spread his spiritual thoughts in all directions of this small lonely mountain through the dense network of the four great arrays, spreading to every corner of the large array.

The formation seemed to be a part of his extended body, spreading to the mountains and underground. All the creatures in this little lonely mountain, even the mustard seed-like dust particles, are also in its senses, and they also sense the movements of all the monks in this mountain into their own spiritual thoughts.

This is the center of the great array that has been changed after the guidance of the sword spirit, which is more than ten times more agile than the original, and more importantly, the dependence on the leylines has been greatly reduced, and when necessary, as long as enough yuan stones are filled, it can be directly run, of course, the yuan stones that will be consumed will be a huge amount.

At this moment, every move of the people up and down this small lonely mountain was in Qin Chong's spiritual thoughts, and Qin Chong was also searching for what he wanted in the chaotic conversation among the concentrating followers.

With so much information, all of it has to be filtered, it's a very difficult thing to do, but no matter how hard it is, it has to be done. Qin Chong didn't fully believe that these people left behind at the moment, just like Xuantian also had spies in other sects, there weren't a few moles in that family?

It took several hours before Qin Chong withdrew from this state, closed his eyes, leaned back on a chair tiredly, and rubbed his aching head with his fingers.

"Sword Monarch, you can be sure that among the more than ten people who are locked, it must be the internal response of the Wuji Sect?"

"Of course not, but this kind of thing can't wait until the evidence is mastered to deal with it, the two armies are fighting, whoever has the initiative in information will take the lead, so just suspicion is enough. ”

After a pause, Qin Chong said again: "On the surface, this matter seems to be dominated by the Wuji and Futu families, and the rest of the people take advantage of the fire to rob, but in fact, these two families should have colluded with the Shangqing Sect that intended to touch my Xuantian early on to design this change, the reason is very simple, those few together did not shake the energy of Xuantian, only the Shangqing Sect, which is also one of the Five Holy Sects, has this possibility!"

Jian Ling didn't answer, she also understood that it seemed that this kind of big sect often had a big plan, and if it didn't move, it would be interlocking, and it would never stop until it achieved its goal.

And the Shangqing Sect is located in the cold and bitter land of the extreme north, and it is not a day or two to covet Xuantian, so it is inevitable that there will be a traitor in Xuantian.
