Speaking of the previous mutation, in fact, the person who knew it best was not Danchen and Gu Gu, or even the Shattered Star Sword, but it was probably the Immortal Domain Monk who was controlling the Immortal Vientiane Attack Law Formation Base at that time!

Danchen clearly remembered that when he came out, he saw that the faces of the five Immortal Domain cultivators were pale, and they looked like they were seriously injured, they were probably injured because of that mutation, so they might also be the ones who knew the mutation best.

But......

Now the people who most likely knew what happened in that short moment were all dying, dead and quiet, and turned into ashes under the dragon flame of the ancient grub.

Danchen and Gu Gu looked at each other, especially Gu Gu, and there was only a wry smile on his face.

"Ancient ......"

"Don't say anything now, although I have lost the possibility of understanding the real situation, after all, I have also obtained the body of the dragon because of this, and this transaction is not a loss. Gu Gu smiled then, but in fact, everyone understood that although its body was refined by the essence of 100,000 monks, it was actually not really comparable to the dragon clan in ancient times, the reason was very simple, at the time of the Ten Thousand Heads Sacrifice, the dragon qi absorbed by this dragon body was too little.

"Gu Senior, you still refuse to tell me why you killed these Immortal Domain cultivators?" Dan Chen turned his head to stare at Gu Mo, although it was said that Gu Mo's life had been in his hands because of the Ten Thousand Beast Diagram fragments, but in fact, Gu Mole and Skeleton Devouring Rats were completely different.

The Skeleton Eater gave his soul origin to Danchen, and it couldn't lie to Danchen, let alone hide anything from Danchen's questions, and even if he wanted to commit suicide, it had to be allowed by Danchen. However, there is such an existence as the Ten Thousand Beasts Diagram Fragment between Gu Gu and Danchen, although its life is also controlled by Danchen, but Danchen can only control the death of Gu Gu.

In addition, Gu Gu can use silence to avoid any questions from Danchen, and even lie to deal with it.

At this time, Gu Yu chose to avoid: "Danchen, it is necessary to kill them." ”

"I want to know why. Danchen pressed forward step by step.

Gu Gudong shook his head lightly and said, "I don't think I can tell you the reason yet, but please believe me, I am definitely doing this for the sake of thought." ”

Danchen looked at Gu Mo quietly, and his intuition told him that Gu must have something extremely important to hide from him, but Gu Mo himself chose not to say it, and he had no way to force Gu Gu.

After a long time, Danchen finally let out a long sigh and said, "Okay then. If the ancient predecessors don't want to say it now, then I'll wait until the day you want to say it, or I'll find out the truth myself. ”

Danchen is sending a signal to Gu Gu, even if you don't tell me, I will definitely find out everything with my own strength.

"Whatever you want......" Gu Yu sighed softly, but he secretly sighed in his heart that he didn't know how long he could hide that secret that could never be said, it couldn't follow Danchen forever and kill every Immortal Domain monk that Danchen met! Besides, it was not difficult to find out this secret at all, after staying here for a long time, Danchen would definitely be able to find some clues.

"Hey, it's a while to be able to hide it. Even I couldn't imagine what crazy things Danchen would do once he knew the truth of the matter. All I can do now is wait. Gu Yu secretly sighed, in fact, it also understood that Danchen was a person who had experienced a hundred tribulations, and there would not be too obvious differences between telling him the truth now and Danchen discovering the truth after a while, in just a few days, no one could change a person's character, if Danchen really found that there was not only Song Ye's essence blood among the 100,000 essence blood, then he ......

Gu Gu didn't dare to think about it, referring to Danchen's previous way of doing things, it could only choose to conceal it!

At this time, Gu Yu even thanked the Immortal Domain cultivator a little in his heart, if it weren't for the fact that they used the powerful Immortal Vientiane to make a mess of the surrounding environment and make it unrecognizable, maybe Danchen would have discovered the truth a long time ago, and discovered that the place where he was actually so familiar to him......

A month ago, there must have been an immortal realm venerable-level existence in this place that used the power of immortal Vientiane, under the influence of this supreme force, everything in this place changed, such as the Moon Mountain City, which had not fallen for ten thousand years and was guiding countless monks every day, collapsed and turned into powder when the immortal Vientiane came. For example, many of the hundred thousand mountains of the great mountain have their tops cut off...... The only thing that hasn't changed is the space below Yueshan City back then, this space where Danchen once stumbled upon the sleeping golden dragon bones and ten thousand beast diagrams!

Before Danchen left Biyou Mountain to go to the Hanging Mountain, his vision was actually very small, the only thing he knew was that there was Liuyang Cave on Biyou Mountain, and there was a vast Earth Wisdom Realm than Liuyang Cave, and in the entire Infinite Continent, there were countless places that were even bigger than Earth Wisdom Realm.

Danchen never knew that in the eyes of some of the strongest people who had the strength to oversee the entire Infinite Continent, the Earth Wisdom Realm and the other ten realms around it were collectively called ...... Far East Coast!

Even if Danchen wanted to get close to the legendary Infinite Sea with his current strength, it would be impossible to do it without a few decades of starting from Biyou Mountain, but in the eyes of the strongest, the Earth Wisdom Realm and other ten realms were all places very close to the Endless Sea, which could be collectively referred to as the coast.

The place under Danchen's feet now is his homeland!

When Danchen said his choice in Futu Tower, Daozun already knew this, so he took more care of Danchen. After arriving here, Gu Yu found out what this place was the first time, so he repeatedly blocked Danchen from contacting the truth, and later the Black Tower Command Fu was born, and it also discovered this secret, so it was able to restrain its desire to destroy all beings in the Immortal Domain, just because it didn't want Danchen to suffer something too early.

Later, when the Devouring Rat appeared and was ordered to sense the dragon qi here, it also sensed that the dragon qi here was somewhat familiar, but it instinctively chose to give up that terrible conjecture, and self-righteously told itself that it did not have much dragon qi in contact with, and perhaps all the dragon qi in the world was like this......

In this way, everyone who discovered the secret chose to remain silent without any consultation, and they didn't dare to imagine what would become of Danchen when he found out that he had lost not only Song Ye's friend, but perhaps all the people close to him......

"It may not take long for the aura of the battle here just now to be discovered, and a project as big as the Ten Thousand Heads Sacrifice will not only be known to the dozen or so monks we have encountered, so I think it would be better for us to leave as soon as possible. Danchen saw that Gu Gu had been silent, and he didn't know what he was thinking, so he had to make his own decision: "Gu senior, your current body is too ostentatious, do you want to try if you can transform into a shape?" Or simply enter the Medicine King Palace, and I will take you to escape?"

The more places he walked, the more likely Danchen was to discover the hidden truth in this area, how could Gu Yu allow Danchen to run around like this? Danchen, I think you have also seen the strength of these people in the Immortal Domain, although you are all proud of the sky and can skip the level to challenge, but no one can guarantee that nothing will happen in the future, so I suggest that we find a safe place to place the Medicine King Palace, and then improve the martial arts realm of a few of you as soon as possible. ”

Danchen didn't doubt him, and after a little hesitation, he nodded and said: "What the senior said is right, almost all the people in the Immortal Domain we met have the strength to surpass the Taiwu Realm, and it is indeed dangerous to break through this place with the strength of the five of us, but now that we are in the enemy realm, where can we find a 'safe' place?"

Gu Yu smiled and said, "Have you forgotten? We have a seventh-order Xuan Array! As long as we can successfully release the power of the seventh-order Xuan Array, then unless it is the Holy Venerable himself, no one will be able to discover us here!"

Danchen raised his eyebrows, pointed to the surroundings and said, "Ancient seniors, you mean...... Here?"

"Yes, this is it!" Gu Gu said confidently: "If you want to use the seventh-order Xuan Array, you must release the Medicine King Palace, but in the short period of time when the seventh-order Xuan Array does not work, the Medicine King Hall will still cause some breath fluctuations." We don't know much about this place, and we don't know if we will encounter tricky enemies when we get to the next place, and you don't have enough time for the bull-faced old ghost to set up the formation, so this place is the safest at the moment, because the Immortal Realm Miscellaneous in this vicinity is all dead!"

I have to say that Gu Yu's words are very reasonable, and even Danchen is greatly impressed. It was right, as long as it wasn't for the Holy Venerable's own visit, even if there would be a large number of Immortal Domain cultivators rushing here because of the previous movements, they would definitely not be able to find the Medicine King Hall that was protected by the Seventh-Order Xuan Array, even if the Medicine King Hall might be right under their noses.

Without further ado, Danchen immediately sacrificed out of the Medicine King Palace, and then jumped into the Medicine King Hall with Gu Gu.

The Ox Face Array Spirit in the Shattered Star Sword had already received instructions from Danchen and Gu Gu, and at the moment of the arrival of the Medicine King Palace, he did his best to desperately make the Seventh-Order Xuan Array work.

In less than a breath, a faint dark green light curtain appeared in the sky above the entire Medicine King Palace, firmly guarding the entire Medicine King Palace.

Of course, this layer of faint dark green light curtain can only be seen by Danchen and the others who are inside the Medicine King Palace, and the people outside can't see this thing at all, as long as they don't get the permission of Danchen or the Ox Face Array Spirit, anyone who comes to this place will only see the dilapidated scene left behind after the Great War.
