Although the Nightmare Beast didn't tell Cheng Yu everything, it was only the last sentence of his disappearance, but it was the most valuable one. This at least let Cheng Yu know the reason for the destruction of the Holy City, even if he was not sure if it was because the Holy Clan had mastered the cultivation method of Duodan, but it was enough.

This also made Cheng Yu understand that he really has to be low-key.

However, although the immortals in the fairy world are high, it is absolutely impossible to stay in the human world unless there are special circumstances. Because there is no immortal qi in the human world, although they can also absorb the aura, but they are transformed into immortal qi through aura, but they have not even reached one ten-thousandth, and it can only be said that it is better than nothing.

They are not like the human realm monks during the tribulation period, after the tribulation period monks successfully cross the tribulation, the gate of the fairy world will be opened, so they can absorb the immortal qi from the gate of the fairy world.

However, for the immortals who were already immortals and came from the upper realm to the lower realm, there was no way to open the gate of the immortal realm, so they naturally could not obtain the immortal qi from the gate of the immortal realm.

Without the qi of immortals, the realm of immortals cannot be advanced, so under normal circumstances, no immortals are willing to come to the lower realm. Therefore, Cheng Yu didn't have to worry about the fact that he had nine primordial gods to spread to the immortal realm.

In this case, I think I am safe for the time being. On the contrary, after ascending to the immortal realm, I am afraid that it is not so safe.

However, Cheng Yu is not a timid person, so he does not dare to fly to the immortal realm for this reason. On the contrary, since the enemy of his holy clan is from the immortal realm, and the enemy of his previous life is also in the immortal realm, then he must go to this immortal realm.

Not only does he have to go to the immortal realm, but he also has to quickly improve his strength and ascend to the immortal realm as soon as possible.

Now that the Nightmare Beast has been encountered, I believe that Cheng Yu will not be allowed to touch it now, so as not to be entangled by Cheng Yu to ask this and that. So Cheng Yu didn't have to worry, so he released all the Xinhe.

With everyone walking together, it was suddenly a lot more lively.

"Senior Brother Yu, what did you encounter in your dream this time?" As soon as he came out of the mountains and rivers diagram, Xinhai couldn't wait to ask Cheng Yu a question.

Because the dream created by the nightmare beast is only Cheng Yu's inner demon, even if Cheng Yu allows Xinhai to see the outside world in the mountains and rivers diagram, and Cheng Yu sees the dream world Xinhai has no way to see.

So the moment Cheng Yu entered the dream, the outside world they saw in the mountains and rivers was all nothing, and they even lost contact with Cheng Yu completely.

Therefore, when Cheng Yu entered the dream world, all of them were very worried about Cheng Yu, for fear that he would have some accidents in the dream world.

Although it was a very difficult period of time, but now that Cheng Yu is fine, everyone is overjoyed, and they have finally survived this catastrophe.

However, now that Cheng Yu is fine, everyone is curious about the dream that Cheng Yu entered.

"There's no way to say this thing, this is your own inner demon, if you want to know so much, I can go find the Nightmare Beast again, and let you experience it for yourself!" Cheng Yu said with a smile.

This time his inner demon was Ye Qian, but he didn't want to talk to everyone about it. Once it involves other women, now these women are afraid that they will feel uncomfortable again, and he doesn't want to block the hearts of several women.

"Forget it, we don't want to try, but then again, didn't you say that you would break through after passing the test, why didn't you break through this time?" said Xinhai with a smile.

"I didn't say that I would be able to improve my realm 100% if I passed the test, although I didn't improve my realm, but my strength went further. After I have stabilized my strength, I am ready to use the cultivation array to break through in advance!" Cheng Yu said with a smile.

This time he didn't let him break through, but once again he overcame his inner demons, his comprehension of the Heavenly Dao went to the next level, his strength increased greatly, and it was not far away to break through again.

However, he urgently needs to improve his strength now, and when his cultivation is stable this time, he will improve again. If he reaches the middle stage of the merger, then his strength will go further, and even a true master in the middle stage of Mahayana is not afraid at all.

"So fast?" Everyone was shocked, how long has Cheng Yu's realm improved, and he can actually improve again, this is too fast!

Cheng Yu smiled and said nothing, the speed and slowness of the improvement of strength also pay attention to chance. But this kind of opportunity is not something that everyone can grasp, although others see that his cultivation is improving quickly, but who knows what he has experienced?

Although he did succeed in passing the Nightmare Beast's dream test in the end, he still felt a chill in his back and a feeling of heartache in retrospect.

Even though he now knew that it was just a dream, not a real reality, his feelings were real, and the pain was really uncomfortable.

And if he hadn't woken up at the last minute, he would have been a dead man by now. Therefore, although this method can quickly improve his strength, he is really reluctant to try it again, because this method is too extreme.

Besides, as the number of times he enters the dream realm to experience more and more, the effect will naturally get worse and worse, but the danger is getting bigger and bigger, otherwise Cheng Yu would not have broken through directly this time, but only improved some strength.

Therefore, it is better not to try this method lightly, and down-to-earth cultivation is the king.

"Don't envy this kind of thing, although the rapid improvement of the realm is enviable, but life is more precious. Moreover, this method of raising the realm is not acceptable to everyone. We also saw corpses everywhere when we came here before, which is enough to see how dangerous this method is. Xinyun said.

"Senior Sister is right, it is a good thing to be able to improve the realm, but it also has to be life. Although I don't know what Senior Brother Yu experienced this time, I can imagine that what he experienced was definitely not as easy as we imagined. If we really let us try, we may not be able to come out alive, so let's cultivate honestly!" Xinhe also spoke.

This is completely fighting with life, if you can't pass it, you will die, there is no room for anything, judging from the dead corpses they saw, the pass rate is obviously not five or five, maybe not even ninety-one, who dares to try it easily?

That is, a special person like Cheng Yu, first, his strength is strong enough, and his ability to protect himself may be relatively great. The second Cheng Yu is the bloodline of the Holy Clan after all, presumably if he really can't hold on, then the Nightmare Beast may also open the net and leave him a way to live.

But if they try, once they fail, then there is no emotion to talk about, and if they die, they will really die.
