Now that it is the autumn of wind and rain, it is extremely easy for Xuanqing and Mu Chenfei to infiltrate the demon clan, not because the demon clan doesn't care, but because the large army is almost all gathered near the Ethereal Mountain, and they can't take care of the other defense lines at all.

As for the outflanking of the large army, it is not impossible, but with the four clans all having true immortals in charge, anyone who goes will be discovered, Mu Chenfei's cultivation can only barely avoid the induction, and Xuanqing's cultivation cannot alarm the demon clan at all.

Don't look at the war between the four clans so lively, there are still many people who are greedy for life and afraid of death, and these people who are greedy for life and afraid of death can't stay in the human race at all, so they can only choose to go to other races.

At this time, both clans want each other's people to run to their own territory, and the battle is easy to win, not to mention, it's a big deal to check after the war.

The cultivators of the True Emperor Realm ran to the demon clan to hide, and the demon clan also acquiesced, and if they could reduce the burden of the war a little, they would reduce it a little, and even the demon clan also announced that as long as they entered the demon clan, no matter what, they would not be liquidated.

Therefore, Xuan Qing and Mu Chenfei easily entered the demon clan and went to the location of the Heavenly Array Cave Heaven.

Back then, Xuanqing relied on a special formation opened up by the Blood Killing City, and took the Dharma boat to the Heavenly Array Cave, and at that time, Xuanqing couldn't help but cultivate to a low level, even the formation attainment was also extremely low, and the Dharma Boat was at a height of ten thousand feet, and Xuanqing could not know the specific location of the Heavenly Array Cave.

And the rumor of the demon clan is not a heavenly array cave, but a human inheritance, which has many treasures, and now the cultivators of the demon clan have been summoned to the vicinity of the Ethereal Mountain, and the two of them are unable to catch the cultivators to ask, and the ordinary demon clan has only heard about it, where does anyone know the detailed location.

Xuanqing took Mu Chenfei to the Blood Killing City, entered the city, and followed the memory to the location of the teleportation array.

What made Xuanqing helpless was that in order to prevent the human race from retaking the Heavenly Array Cave Heaven, this teleportation array turned out to be a teleportation auxiliary array, and after this array was opened, it did not have the ability to teleport, but needed the summoning of the other side, and this teleportation array had an effect.

Although it is troublesome, with Xuanqing's spatial attainments, it doesn't matter if you supplement the formation or not, use the law of space to perceive the other end of the formation, directly open the void, and drill in without hesitation.

Mu Chenfei frowned and saw Xuanqing disappear into the spatial crack, with his cultivation, it was easy to follow Xuanqing behind, but after the space, Mu Chenfei didn't know where it was, and he was really afraid that there would be a trap behind.

After hesitating, Mu Chenfei thought that there should be no true immortals behind, otherwise the true immortals would have appeared a long time ago, as for the other demon scattered immortals, no matter how many people there are, Mu Chenfei can also maneuver around, and then follow Xuanqing into the spatial crack.

Xuanqing used the law of space to come to the position of the original law boat, and saw that Mu Chenfei did not follow behind him, knowing what Mu Chenfei was afraid of, after all, the two had not known each other for a long time, but Xuanqing helped Nangong to break through the scattered immortals, and he didn't want to be a spy of the human race, and few people knew about the existence of Lingying, so Mu Chenfei still had a little trust.

Just when the spatial crack was about to close, Mu Chenfei appeared beside Xuanqing, looked around cautiously, and saw Xuanqing looking at him, his face turned red, and he forcibly explained: "There is no cave breath around here!"

Xuan Qing rolled his eyes and said: "Of course not, the demons of many cities came here to take a magic boat and flew for three days, the specifications of this magic ship were still low at that time, and I didn't know what level it was, so it might be a little troublesome to find." ”

"At that time, you thought it was troublesome, although I was not good at space, and I couldn't find this place according to the teleportation formation, but you don't underestimate my thousands of years of advancing to the Scattered Immortals, you look at my means. ”

After speaking, I saw Mu Chenfei pinching the trick with both hands, and hundreds of golden butterflies appeared around him instantly, Mu Chenfei fed each golden butterfly a trace of aura, and said to the golden dee: "Go, find a place similar to this aura!"

Then the Golden Butterfly flew quickly, and its speed was no less than that of a cultivator in the True Emperor Realm.

"Senior brother, I don't know what kind of spell this is?"

"Although I'm not sure if you're my junior brother, but I don't look like you're fine, plus the formation attainments are really outstanding, so I'll call you a junior brother, this Kingdee seems to be very simple, but with my immortal creation, Kingdee's spirituality is extremely high, so you can also understand my orders, look for where is the right place, and when you advance to the rank of Scattered Immortal, you can also use these small spells." Mu Chenfei said slowly.

"The principle is like this, then wait for the good news of Senior Brother's spell!" Xuan Qing said with an expression that was so principled.

Then the two waited for a full day, and finally a golden butterfly came back from the southeast, Mu Chenfei took the golden butterfly back into his body, closed his eyes to perceive everything the golden butterfly saw, and then showed a surprised expression and said: "Found it, junior brother come with me!"

Then Mu Chenfei quickly flew towards the southeast where the golden dee came back, Mu Chenfei, who was a scattered immortal, was extremely fast, and Xuanqing disappeared in front of his eyes in the blink of an eye.

But compared to speed, Xuanqing was not afraid of anyone, and the law of space immediately appeared, and a flicker caught up with Mu Chenfei.

The speed of the two was extremely fast, and in just one hour, Mu Chenfei came to the Kingdee sensing position, and Xuanqing also did not lag behind, and when he saw the familiar scene, he immediately said: "This is it, there is nothing wrong!"

"Okay, let's go in quickly!" Mu Chenfei said impatiently.

"Wait a minute, brother! there's something wrong here. ”

"What's the problem?"

Xuan Qing observed for a moment and said: "There is a vigilant demon array here, although it does not have any power, but once the person who breaks into the array at will will feel it. ”

"Can you sneak in or break the formation quietly?"

"Yes, it will take a little time!"

Mu Chenfei nodded, then stepped back to look at Xuanqing's methods.

I saw Xuanqing attracting the surrounding demonic qi to slightly test the formation, this trace of demonic qi could not touch the alert formation, after all, the demonic qi moving with the wind is a common thing, if the vigilant formation is so sensitive, the true immortal of the formation will have to be busy to death, and come to check the vigilant formation every day.

Xuanqing's divine sense was attached to the demonic qi, and soon the structure of the formation appeared in Xuanqing's mind, and then he said to Mu Chenfei: "Senior brother, follow closely behind me!"

Mu Chenfei nodded, Xuanqing walked very slowly, and Mu Chenfei also followed closely.

I saw that Xuan Qing attracted the surrounding demonic qi and a special fluctuating demonic qi shield appeared around his body, this shield was extremely loose, but if a cultivator observed it carefully, he would find that the tightness of this shield was exactly the same as that of the vigilance formation.

The two of them entered the formation, only to see that the shield was constantly shifting, Xuanqing and Mu Chenfei also followed the shield, it turned out that the shield was used by the formation as a running demonic qi, and the shield and the formation were integrated.

The two of them followed the shield for three hours, and finally the shield came to the other end of the formation, Xuanqing directly moved the shield out of the formation, and then the energy of the shield was pulled back, but the entire alert formation was calm and there was no fluctuation.

Xuan Qing and Mu Chenfei came to the location of the original red light again, and at this time, Xuan Qing arranged a sealing formation around him, not the seal entrance, but the movement when the seal opened the cave sky, if there was a huge energy fluctuation, the nearby vigilance formation would also be touched.

The seal was completed, and Xuan Qing and the others entered it, Xuan Qing closed his eyes and carefully sensed the surroundings with the laws of space, but for some reason he couldn't sense anything.

"The Heavenly Array Cave Heaven has been arranged by the master for thousands of years, how could he not think of guarding against the laws of space, take out the identity token, and sense it carefully!" Mu Chenfei said.

Xuanqing nodded and took out the identity token, but seeing that Mu Chenfei didn't take it out, he asked curiously, "Why didn't Senior Brother take it out and sense it?"

"Ahem, my, my Heavenly Sword Order was lost, and it was the Heavenly Sword Gate that reissued another piece, but it was the Blue Order of the Heavenly Sword lineage. Mu Chenfei said embarrassedly.

"Cut, did you exchange the identity sword order of the Heavenly Array One Vein for the Sword Order of the Heavenly Sword One Vein, so that you can enter and exit the Heavenly Sword One Vein Cave Heaven and practice the way of the sword!" Suddenly, a white light mirror appeared in front of Xuan Qing and the others, and a voice came from inside.

Mu Chenfei immediately rejoiced when he heard the voice: "Senior sister, it's really you!"

Then Lingying walked out of the light mirror, and said with a smile: "Yes, do you think Xuanqing is as ungrateful as you?"

"Senior sister, how can I ......?"

"The sword order is bound to your soul, as long as you don't lift it, you can sense it, you can find it wherever you lost it, don't tell me that the sword order was picked up by a true immortal of another race!" Ling Ying said with a cold face.

"This, this, that" Mu Chenfei hesitated, and then Xuanqing broke the siege and said: "Senior sister, don't blame senior brother, aren't we here to save you, by the way, Senior Sister Lingying, why did you come out?"

"Senior sister, I haven't been idle all these years, I have worked hard to dedicate myself to research, and finally cracked the formation left by the old man, but because I am a formation spirit, I can't leave the cave for too long. Lingying said with a grin.

"Then senior sister, let's go in and talk. Xuanqing said immediately.

"Don't worry, there is still time for this, but it's really not good in this place full of demonic energy, come in with me!"

After Ling Ying finished speaking, the light mirror appeared again, and he pulled Xuanqing back to the cave.

And Mu Chenfei touched his nose and followed closely, and the three of them entered the cave, and Ling Ying waved his hand and took himself and Xuanqing directly to the residence of the original Heavenly Array.

Mu Chenfei saw the residence and immediately said, "Senior sister, you, why did you bring us to the old man's mansion of Shizun, ...... like this?"

Lingying waved her hand and interrupted: "Everyone has been dead for so long, if you really have respect, why would you go earlier, come to Senior Brother Xuanqing and let Senior Sister take the test and teach you the formation." ”

After Ling Ying finished speaking, with a wave of his hand, the surrounding scene changed rapidly, but it was covered by the phantom formation formation, so that the people who entered the formation could not quickly find the formation base.

Xuan Qing smiled slightly, this different formation has repulsion, and it is easy to crack the illusion according to repulsion.

But then Xuanqing's smile quickly disappeared, because after a few breaths, Xuanqing didn't find any rejection, as if he was really somewhere else.
