"Why are they in a hurry to use this method to collect the undead as sacrifices, in the past, even if the Heavenly Demon Temple collected the undead, it was only done in secret, and something like this that directly led to a big war has never happened." Mu Xuan said with some doubts.

"The Heavenly Demon Palace's collection of undead must have their conspiracy, but as for what, I don't know." Mu Yu also sighed lightly and said.

Hearing Mu Yu's light sigh, Mu Xuan's heart was a little solemn for some reason, although he didn't know what the Heavenly Demon Palace wanted to do, but it was certain that they must be brewing a big conspiracy, otherwise, who would have nothing to do to collect so many undead, and the pace of their collection has obviously increased recently, does it mean that they are about to be unable to bear it

"Demon Clan, what do you want to do?"

"The Northern Regions are in turmoil, the Beast Gate is still continuing to expand its territory, and wherever they go, those who do not obey will completely slaughter the sect and destroy the country, which undoubtedly accelerates the degree of collecting the undead in the Heavenly Demon Palace, and the quality is insufficient, and they are supplementing it with quantity." Mu Yu glanced at Mu Xuan and said: "As for the Tianhuo Martial Pavilion, in the years since you left, the people of the Xuanzong in the Northern Regions, that is, the sect you stayed in before, have been helping Xiao Feng and vigorously developing the Tianhuo Martial Pavilion, if it is normal, the Wild Beast Gate will not invade the Tianhuo Martial Pavilion at all, but unfortunately, there is one more Heavenly Demon Palace, with the help of these powerhouses in the Heavenly Demon Palace, Xuanzong and the Tianhuo Martial Pavilion can only fall into disadvantage. ”

"In the past few months, Xuanzong's sphere of influence has shrunk significantly, and he can only gradually shrink to the Yalan Empire, and we also received information at that time, and Xiao Yu and the others rushed to the Yalan Empire after knowing the news, and Yanna also went."

Mu Xuan's face was gloomy, this damn Heavenly Demon Palace, sure enough, would not stop for a moment.

"When Xiao Yu and the others left, I also sent some strong people to follow......

Mu Yu was not surprised by Mu Xuan's words, nodded slightly, and said, "Well, this time you go to the Yalan Empire, I will send some strong people whose strength has reached the level of Wuzun Dacheng or above to follow, and they know more information than you, so you will be able to understand the situation in the Northern Regions in advance......"

Mu Xuan thought for a moment and nodded.

Seeing this, Mu Yu smiled and said, "Don't be in a hurry to leave today, the Land of Judgment is too far away from the Northern Regions, and if you fly back, it will take at least a month or more, so you must build a space tunnel......"

Hearing this, Mu Xuan was stunned, the space tunnel can be created as long as the strength reaches the strength of the martial venerable, but if you want to create a space tunnel so far away from the Northern Regions as the land of judgment, it is not something that ordinary martial venerable can do, but fortunately, Mu Yu is now a semi-saint-level powerhouse, and it will not be very difficult to create it.

"Last time, I used a temporarily constructed space tunnel to send Xiao Yu and the others away, and since then, I have been preparing a stable space tunnel, if it is successfully constructed, it will be able to become a passage connecting the Northern Regions in the future...... Mu Yu said with a smile.

Mu Xuan nodded, also breathing a sigh of relief, if he could really build a spatial tunnel that went straight to the Northern Regions, it would undoubtedly save him countless hours later.

"You should have a good rest today, these days, you should be tired too!" Mu Yu smiled.

Mu Xuan did not refuse, nodded, suddenly remembered something, took out the jade-like jade slip given to him by Dan into the soul from the storage spirit ring, and handed it to Mu Yu: "This is the so-called clan meeting invitation of the Dan clan, they said to let me pass it on to you."

Hearing the word clan meeting, Mu Yu's palm suddenly trembled, although the arc was extremely small, it still did not escape Mu Xuan's eyes.

Mu Yu's eyes were firmly fixed on the jade-like jade slip, as if he was thinking about something, and after a while, he put it into the storage spirit ring, and said softly: "Okay, don't worry about this in advance, let's build a space tunnel first." ”

"Hmm." Mu Xuan nodded slightly, although Mu Yu did not fluctuate much on the surface, he could feel that Mu Yu was thinking about something.

"It seems that this so-called Dan clan meeting is indeed very special."

Seeing Mu Xuan's flickering eyes, Mu Yu just smiled slightly, did not explain the so-called clan meeting, gently patted Mu Xuan's shoulder with his palm, and said with a smile: "Let's go, go back first, take a good rest, these half a year, presumably you have not had an easy time, I should have let you rest for a while." ”

Mu Xuan shook his head indifferently, all these years of experience have made him accustomed to this kind of running and tiring, in order to protect some things, he always has to pay, but what makes Mu Xuan a little relieved is that now he is finally and truly a first-class powerhouse who can take charge of himself

"When I wait for the space tunnel to be built, you will be able to leave for the Northern Regions, hehe, speaking of which, it has been many years since you left there, and it is time to go back and see!" Mu Yu said with some sighs, thinking that back then, when Mu Xuan first left the Yalan Empire, he was still just an immature teenager, but now, the young man of that year has completely become a man of the year on this big 6.

Mu Xuan nodded silently, and he was also a little stunned in his heart, unconsciously, he had been away from the Yalan Empire for several years, I don't know what happened to Master Xiao Feng and the brothers of Xuanzong over the years?

……

After returning to the Land of Judgment, Mu Xuan's next days undoubtedly became much more leisurely, and he stayed in the independent space of the Land of Judgment all day long, meditating on pranayama and cultivating!

And under this kind of leisure, the three days also passed slowly, and the space tunnel built by Mu Yu gradually tended to improve......

When Mu Xuan rushed to the mountain behind the independent space of the Land of Judgment, a pitch-black void about ten zhang in size was slowly appearing on the stone platform at the top of a mountain peak, and a violent spatial force surged out from it, and finally spread out......

"Father, did you succeed?"

Mu Xuan's figure moved, appeared not far from the wormhole, looked at the old figure in front of him, and said happily.

"Hmm!" Mu Yu smiled and nodded, then turned around, looked at Mu Xuan, and said, "Everything is ready......

"Well, when are we coming out?" Mu Xuan nodded, and then muttered.

"I'm afraid it will take a few days, the space tunnel has just been successfully constructed, and it is still unstable, and in these few days, I think, maybe I should find some other helpers, there must be a lot of Heavenly Demon Hall powerhouses on the side of the Beast Gate, so we must have thorough preparations." Mu Yu said.
