Xuanqing used his divine sense and divine yuan to test a few times, and found that he didn't find any flaws, knowing that he couldn't compare with his senior sister with the formation.

Thinking about it, Xuanqing's formation was taught by Lingying, plus Lingying had lived too long, and he was born in the formation spirit, which can be described as extremely talented, and Xuanqing felt very normal.

Xuanqing's formation attainments are indeed far inferior to Lingying, but this does not mean that Xuanqing has no other way, after speaking, a strange mystery suddenly appeared around Xuanqing's body, and the surrounding illusions suddenly began to be chaotic.

Before Xuanqing could observe the root of the formation, the formation was already shattered, of course, it was also because Lingying didn't use much Divine Yuan at all.

The scarcity of divine elements also caused the formation to disperse, but there was no backlash force appearing.

"Senior Brother Xuanqing, what kind of mystery is this, why has Senior Sister never seen it?" Ling Ying saw that this mystery was almost naturally restrained, and couldn't help but ask rudely.

Lingying has a great kindness to Xuanqing, so she didn't hide it: "Because of some chances, I rubbed some edges with the mystery of time, and as for how much time the mystery brother can't learn from." ”

Mu Chenfei interjected: "What? It's actually the mystery of time, doesn't it mean that the Nether Realm can't comprehend it at all?"

"With the help of the True Immortal Divine Power Spell, I can barely comprehend it, and the Nether Realm can't comprehend it, this is a bit big. Xuanqing said modestly.

"Senior brother is really blessed, senior brother is envious!" Mu Chenfei said with jealousy.

"Although this mystery is weird, the effect is not very great when fighting, and it is extremely easy to hurt oneself, senior brother's golden law is infinitely powerful, how can I envy it. ”

"Senior brother doesn't know this, this time mystery is not much help for combat power, most of the people who cultivate immortals and practice the Tao are for longevity, and once they comprehend the meaning of time, their lifespan will increase greatly, compared to the lifespan of the Heavenly Dao, and once they comprehend the level of the law, then they will really reach immortality, how can you say that the senior brother is not envious. ”

"Prolonging life, at this time, the junior brother doesn't know, and I don't feel anything!"

"At that time, the cultivation time of the junior brother was still short, and he couldn't realize it, with the mystery of time, the junior brother would not have this feeling in the future, there were countless cultivators in the starry world, among which there were many talented people, why did most of the true immortals specialize in the mystery of time, not to break through the ascension, the key is that the mystery of time can fundamentally extend the lifespan, and the breakthrough of the realm is just for a better time for enlightenment. ”

"And this kind of thing? It's my junior brother who is a shallow learner!"

At this time, Ling Ying interjected and said to Mu Chenfei: "Okay, you can't comprehend the mystery of time if you are humble here, it is better to think about how we should leave the demon race." ”

Mu Chenfei said with an embarrassed look on his face: "Senior sister is teaching a lesson!"

Ling Ying has observed many times, and the highest attainment of the formation explains the current situation: "There is a vigilance formation outside, although you and I can completely ignore the vigilance formation, but this formation also has a role to use the loopholes of the Heavenly Array Cave Heaven to support the aura, once the Cave Heaven disappears, the Demon True Immortal will definitely be able to sense it, and too much movement will also trigger the vigilance formation." ”

At this time, Xuan Qing thought for a moment and replied: "What does Senior Sister mean, we must quietly take back the Heavenly Array Cave Heaven, and there are still things left to hide the warning formation?"

"Yes, this is also the reason why I have been staying here, for example, I already know the formation of the Formation of the Cave Heaven today, and it is not a problem to retract the Heavenly Array Cave Heaven, but the difficulty of the problem is that there will be movement, and I haven't thought about leaving things behind. Lingying nodded and said.

Xuan Qing's eyes rolled and said, "Senior sister, I have a method that I should be able to try!

Lingying's eyes lit up, "Let's talk about it!"

......

Three days later, Xuanqing and Mu Chenfei left the Heavenly Array Cave Heaven, and then used the old method to pass through the alert formation, at this time, Xuanqing and Mu Chenfei nodded to each other, only to see that Xuanqing's body suddenly appeared in the mystery of time, and directly entered the alert formation.

Although the vigilance formation is clever, as long as it does not reach the level of the immortal array, the time mystery that touches Xuanqing is suddenly affected, and after a few breaths, the power of the vigilance formation is greatly reduced.

When the vigilance formation was about to dissipate, Xuan Qing withdrew the meaning of time, and Mu Chenfei entered the Heavenly Array Cave Heaven again.

"Done?" Lingying asked.

Xuan Qing and Mu Chenfei nodded, and then Ling Ying waved his hand, and a large mirror suddenly appeared in front of the three of them, and this mirror could actually observe any wind and grass within a radius of a hundred miles outside the cave sky.

The three of them looked at it for a day, and finally a black light appeared, this person had two horns on his head, a black robe, and a demon dragon on his shoulder, which seemed to be a pet.

And this person's face is even more handsome and extraordinary, Mu Chenfei and Lingying saw this person and immediately subconsciously said: "True Immortal Demon Yan"

Looking at the expressions of the two of them, he knew that the True Immortal Heavenly Array should have died at the hands of this person.

True Immortal Demon Yan came to the vigilance formation and saw that the Heavenly Array Cave was still the same, and the power of the vigilance formation was less than one percent.

Then the True Immortal Demon Yan checked more than a dozen times, and found that there was no aura and demonic energy attack, and the time mystery appeared extremely fast, and the emitting was also extremely fast, and the True Immortal Demon Yan could easily sense it when facing the enemy, but after a few breaths, it would be invisible, and the day passed, and the time mystery had long since dispersed.

Time is the foundation of the world's operation, it can be said that time is everywhere, like a big river, suddenly a splash rises, and after a day wants to find the traces of the previous splash, not to mention that Mo Yan is a true immortal, even the golden immortal can't detect it at all, only people who comprehend the mystery of time spend a lot of ability to use time to regress, and will repeat the previous scene.

The investigation was fruitless, and the True Immortal Demon Yan left with doubts, and after half a day, Xuan Qing and Mu Chenfei walked out of the cave again, concocted it in the same way, and used the time mystery to affect the vigilance formation again.

Half a day later, Mo Yan came here again in confusion, still did not find any movement, Mo Yan looked at the cave, and then waved his hand to set a seal at the entrance of the cave, turned around and left again.

It is not an exaggeration to say that Xuanqing and Lingying's formation attainments have reached the limit of the mortal array, and the seal alone cannot prevent the two of them from entering and exiting.

After most of the day, the seal didn't even have any reaction, and Xuan Qing and Mu Chenfei went out again, using the time mystery to affect the vigilance formation.

Then the True Immortal Demon Yan appeared again, this time it was carefully checked dozens of times, but Xuanqing and Mu Chenfei did not use any energy, plus Xuanqing is a person from outside the sky, Mu Chenfei reached the Scattered Immortal, and the array spirit is created by the True Immortal Heavenly Array, the three of them are all people who have left the Heavenly Dao, and it is impossible to calculate the two of them.

True Immortal Demon Yan left again, the two of them affected the vigilance formation again, and after a long time, True Immortal Demon Yan came back, so angry that he sat directly at the gate of the cave to see what was playing on him.

Xuanqing was relieved to see the True Immortal Demon Yan blocking the door, although he couldn't go out for the time being, but this is not critical, the war of the four clans is coming, there are a lot of things for the True Immortals, and the three of them can afford it, what Xuan Qing is most afraid of is that the True Immortal Demon Yan will destroy the Heavenly Array Cave Heaven in a fit of anger.

"Whew! Fortunately, this person didn't attack Dongtian!" Xuan Qing said luckily.

"Senior brother was worried about this, rest assured, this Demon Yan will definitely not attack Dongtian. Lingying smiled.

"Why is that?" asked Xuanqing in confusion.

"Back then, Shizun fully comprehended the formation that could kill the Heavenly Dao, and only when he attracted the attention of the Heavenly Dao would he die, and whether this formation could kill the Heavenly Dao or not, its power was also extremely objective, and it was not impossible to break through the Heavenly Dao blockade and ascend to the Immortal Realm, and the Master did not inform anyone about this formation, and finally died in the cave sky, do you think the demon clan will really give up a chance to ascend to the immortal realm?"

"I see, but will the Heavenly Dao use this person to destroy the Cave Heaven and completely cut off the Heavenly Array. Xuan Qing said worriedly.

"The way of heaven has the strength to demagogue people's hearts and calculate the world, but it can't calculate people's hearts, even if Mo Yan wants to destroy the cave heaven in a fit of anger, but this person also has to take into account the other true immortals of the demon race, you must know that the whole world will be pulled by here, will Mo Yan destroy this place will be because he has found a formation, and when the time comes, not only the demons will not agree, I am afraid that the whole world will be embarrassed by the demons. Lingying said confidently.

"Senior sister said this, junior brother has the bottom of his heart, we just need to polish Mo Yan's patience, and when we find out, we won't come back, and that's when we leave!" Xuan Qing nodded.

Mo Yan blocked the entrance to the cave for more than a day, and did not find any abnormalities, and there was no abnormal movement in the vigilance formation, and the True Immortal Demon Yan left again.

After a long time, Mu Chenfei just wanted to get out of the cave, but Xuanqing directly stopped him: "Senior brother, don't worry, there have been many changes here, and Mo Yan may hide and come back to check, and although the Xuanguang Mirror of the cave can view a hundred miles, if Mo Yan doesn't hide a hundred miles, it will be troublesome!"

Mu Chenfei thought about it for a while, so he waited patiently, and then Xuanqing suddenly turned his head and asked Lingying, "Senior sister, I don't know if the master left the Zhutian Immortal Array?"

"Left and didn't stay!" said Lingying vaguely.

"Why did Senior Sister say that?"

"This array is a great threat to the Heavenly Dao, if you really leave the Heavenly Dao, you will sense it, then the cave will not be able to keep it, that is to say, the old man will not dare to stay even if he wants to. ”

"Then why did you say you stayed?"

"There are a lot of books in this cave, although they are all extremely clever, but with the ability of the master, it is enough to collect all the formations in the world, why don't you do this? The reason is that the old man's Zhutian Great Array is obtained from the formation books of the cave, as for whether anyone can understand it from it, it all depends on understanding, of course, the premise is to reach the formation attainment of the immortal array master. ”

"So that's the case, I really want to see what kind of attainments the Zhutian Immortal Array left by the master is, and it is actually on an equal footing with the Golden Immortal, and let the Heavenly Dao calculate. Xuanqing said with emotion.
