Cheng Yu sat alone in the Great Yan Inheritance Cultivation Array of the Immortal Demon Tower, at this time the formation had been activated, and the light around the formation had already covered Cheng Yu, and the spiritual energy continued to flow out of his mountain and river diagram, thus entering his body.

At this time, the nine-branch spirit tree in his body absorbed all the spiritual energy that poured into his body, and he saw that the light of this magical golden tree flashed one after another.

Every time it flickered, this nine-branched spirit tree would appear like Cheng Yu, and I saw this Cheng Yu sitting upright, his eyes closed, and his face was serene.

And the next time it flickered, Cheng Yu disappeared again, turning into a nine-branched spirit tree again. Flickered again, and Cheng Yu's phantom appeared, just like this, it flickered once and changed again, and the constant flickering kept changing, and it was very weird.

Of course, at this time, the real Cheng Yu didn't have the energy but cared about these, he needed to concentrate on his exercises, and constantly absorb the aura from the mountains and rivers for the improvement of his strength and the breakthrough of the realm.

The last time he encountered the Nightmare Beast, after passing the test, his strength took another leap forward. However, although his strength has been greatly improved, this improvement is not enough for him to directly break through the realm.

The stability of this period of time has allowed his realm to slowly settle down, and his strength has also improved slightly, and he is not very far from breaking through, as long as he uses the cultivation array to cultivate, he will definitely be able to successfully break through.

However, it is still only a period of strength improvement, and if you want to break through, it is not so fast, at least it will take a few days.

Cheng Yu cultivated in the Immortal Demon Tower, while the others enjoyed this beautiful scenery.

If this is not in the illusion, it is much better than the Infinity Palace. It's a pity that this kind of place is not something that everyone can enjoy, if it weren't for Cheng Yu's Five Elements Phantom Spirit Disk, it would not be so easy for ordinary people to get out when they enter here.

Fortunately, they didn't have such worries, anyway, as long as Cheng Yu successfully broke through, they could leave this place at any time, and they didn't have to worry about being trapped here by this illusion at all.

"Senior Brother Yu is really right, the aura in this is really very uniform and peaceful, no matter where you go, the aura is the same. A group of people wandered around this fantasy for two days, and Xinluo told what he had discovered in the past two days.

"yes, then it's going to be hard for us to determine the location of the spirit veins!" Kokomi nodded.

"Do you really think there is a spiritual vein in this? don't dream about it, how can a spiritual vein be formed so easily!"

There is no one who doesn't want a spiritual vein, the question is how can the spiritual vein be so easy to find? Just like Cheng Yu said, it is not impossible for a spiritual vein to be slowly formed here for tens of thousands of years, but this probability is too small.

In addition, the aura in each place is very uniform, and in this case, even if there is a spiritual vein, it is difficult to find out. This is equivalent to doing something with a very small probability on the basis of an event with a very small probability, which in his opinion, is basically zero.

"Senior brother, this kind of thing is not accurate, although what Senior Brother Yu said is very right, but it is not completely impossible. Tens of thousands of years, who can tell clearly?" said Xinluo with a smile.

He was not discouraged at all, and he just thought it was playing. Anyway, haven't you been shopping around like this for more than a year?

If he really touches it, it will be a good thing, and he has nothing to lose, so why not do it?

"Since you can think so, then it's the best!" Xinhe nodded, there are some things that can't be forced, and it also depends on everyone's chance.

If Xinluo had this opportunity, it would be good if he really wanted him to find a spiritual vein.

"Do you think those masters can still know our whereabouts now?" asked Lin Yuhan at this time.

"Probably not, after all, we're in the illusion now, are these guys so powerful?" Xinmei shook her head.

"That's it, I don't know how many illusions there are in this Death Illusion Sea, it's good if these guys don't walk into the illusion by themselves, how can they find us!" Xinhai said with a smile.

"I just don't know where they are now?" Sister Nana, can you sense it?" Lin Yuhan then asked.

"I can't sense anything outside of the illusion!" Yao Na said, shaking her head.

Although her curved mirror can sense everything within a radius of forty kilometers, it is only limited to the space where she is, which means that she can sense it inside this illusion, but there is no way outside.

"You don't have to worry, this illusion is always changing, and the moment we enter it, we are no longer where we are. So even if these guys get to where we were, we're no longer there, so don't worry they'll find out where we are!" explained Xinyun.

The illusion of this sea of death is different from that of other places, which are based on a certain place as an illusion. And the illusion here is obviously much more clever, it is based on space to arrange the illusion. And there are thousands of illusions arranged in this space, this kind of strength is really amazing.

As soon as someone enters it, its location changes. And even the entrance has been closed, and unless there is a special method to open it on its own, it is impossible for anyone to enter again.

"In this way, I can rest assured, otherwise Senior Brother Yu is in the breakthrough again, if these guys find it, it will be a big trouble!" Xinluo said with a smile.

"Don't worry, although they are strong, they definitely don't have this ability, so let's stay here with peace of mind!" Xinyun said.

——

At this time, there were six Mahayana masters who did appear at the place where Cheng Yu was a few days ago.

"Senior Brother Wenchang, are you sure they appeared here before?" Wen Jiang looked at the surroundings and saw that there was nothing, and he didn't find any signs of man-made, and asked suspiciously.

"I'm sure, I believe that there will be absolutely nothing wrong with this secret method of mine!" Wen Chang also said with a puzzled expression.

He once obtained a secret method in his experience, and as long as he took anything from his body, he could know the existence of the Lord according to this secret method.

And Cheng Yu once had a big battle in Xuantian Sect, but he didn't expect that Qian Yuzi would actually shed Cheng Yu's blood, and this time he gave this blood to Wenchang, it seems that he had already calculated all this.

So, Wenchang used Cheng Yu's former blood to find Cheng Yu's location, thinking that Cheng Yu and they couldn't run away this time. But when they arrived here, they didn't find any trace of Cheng Yu, which made people a little confused!

Could it be that they can still disappear into thin air here?
