Luo Han and the four of them didn't know about the changes that appeared on the corpse of the demon beast in the secret realm after they left, as well as the last gray light, and even after the four of them walked out of the spatial teleportation channel and returned to the Fallen Sky Range, they didn't see the gray light that also flew out of the spatial teleportation channel.

However, Luo Han, although he did not appear gray light and knew about the abnormal changes in the corpse of the demon beast, but after the gray light came out of the spatial teleportation channel, he still faintly felt something strange, and immediately looked in the direction where the strange light came, that is, the direction in which the gray light left, but at this time, the gray light had already flashed and disappeared, so he could only look at it suspiciously for a moment, and then shook his head.

"Finally came out of this secret realm!" After coming out, Qian Yifei didn't notice the gray light at all, but immediately sighed happily, but soon he frowned and said helplessly: " It's just that after staying in the secret realm for a long time and getting used to the aura concentration in the secret realm, it is a little unaccustomed to returning to the cultivation realm, I originally felt that listening to the strong aura concentration is far from enough, it seems that we need to spend a while to re-adapt to the aura concentration in the cultivation realm!"

Qian Yifei's words immediately made Luo Han, who was puzzled by the strange feeling just now, and Ye Zhengtian and Zhu Lin on the side, suddenly shift their attention to the different spiritual energy concentrations in the two places of the Secret Realm and the Fallen Heaven Mountain Range, and after feeling it for themselves, they all nodded in agreement and agreed.

"There is a big gap in the concentration of spiritual energy between these two places, and I think the reason for this phenomenon is that in addition to the difference in the density and quality of the original number of spiritual veins in the two places, but also because there is no cultivator in the secret realm for I don't know how many thousands of years have not entered it, and the spiritual energy has almost not been consumed, but has been accumulated, which is also one of the reasons for the appearance of that spiritual liquid lake, as for the Fallen Heaven Mountain Range, there has never been a trace of cultivators since ancient times, so the spiritual energy in it can naturally only be maintained at a level, far less than the concentration of spiritual energy in the secret realm。 Luo Han answered at the right time and analyzed the reason.

Luo Han's analysis was agreed by Qian Yifei and the three of them, but they soon let go of this topic, although they were very uncomfortable at this time, and they were very uncomfortable with the sudden decrease in aura concentration, but they had no better way, they could only wait for time to pass and let them slowly adapt themselves.

After finishing talking about the concentration of aura, Qian Yifei's face turned straight, and he said to Ye Zhengtian and Zhu Lin: "Senior Brother Ye, Senior Sister Zhu, the exit of this secret realm is not stable, and the next opening is possible at any time, if we leave directly regardless of it now, maybe after we report the results of the mission to the alliance, before the alliance sends people to come, it has already been revealed by other cultivators in the Fallen Heaven Mountain Range, which is absolutely not allowed."

So in order to prevent any kind of things from happening, please also ask the two of you to arrange a formation here, this formation does not seek any outstanding offensive power and defense, the only requirement is to be secret enough, to be able to cover this area, even if the space teleportation channel is opened, there will be no movement leaked out, so that before getting our notice in the alliance and sending people to come, we can ensure that there will be no accidents to the greatest extent. ”

Regarding Qian Yifei's request, Ye Zhengtian and Zhu Lin were stunned after hearing it, they really didn't think of this just now, but they quickly reacted, knowing that Qian Yifei's worry was not unreasonable, in fact, there were countless cultivators in the Fallen Heaven Mountain Range, if it weren't for the fact that their location was now located on the edge of the Fallen Heaven Mountain Range, there must have been a lot of cultivators passing by and showing the traces of the four of them.

So, after thinking about it for a while, Ye Zhengtian and Zhu Lin nodded at Qian Yifei and said: "Senior Brother Qian, you are right, there is indeed a need for some cover-up here, so as to ensure that the people of this alliance can smoothly take over this secret realm, but after all, this is in the Fallen Heaven Mountain Range, and there must be many masters under the mixture of fish and dragons, so the two of us cannot guarantee that the formation laid out is absolutely impossible for a cultivator to see through and crack it." ”

Hearing this, Qian Yifei smiled, waved his hand and said casually: "Senior Brother Ye, Senior Sister Zhu, please rest assured, if after the formation is laid out, someone still appears here, and cracks this formation, and obtains the information of the entrance to the secret realm, then it means that all this is doomed, after all, we have done everything we should do and can do, and if we can't even keep the entrance to this secret realm, the alliance will not blame it." ”

In fact, in Qian Yifei's words, only the last sentence is the most important, that is, after the formation is arranged, no matter what the situation is, it has nothing to do with them, even if the formation is still cracked, and the secret realm is revealed by other cultivators, there will be no blame in the Treasure Exploration Alliance, and the two of them will have no worries at this moment.

Therefore, then Ye Zhengtian and Zhu Lin began to get busy, while Qian Yifei and Luo Han withdrew from this valley, each standing on the top of an upper mountain, while paying attention to the progress of Ye Zhengtian and Zhu Lin's formation, while paying attention to the movements within a radius of thousands of miles, beware of cultivators who may pass by here at any time.

Fortunately, after this trip to the secret realm, through the practice of constantly dealing with and cracking the ancient formation, Ye Zhengtian and Zhu Lin had a deeper understanding of the way of formation, and the strength of the formation was also greatly improved, so soon the two of them completed the arrangement of all the formation flags and formations, and under the gaze of Luo Han and Qian Yifei, the formation was activated.

In an instant, extremely faint rays of light emerged from the array of flags one by one, intertwining in the air to form a hemispherical light mask, covering almost all of this valley, and when the light mask was fully formed, it disappeared in an instant, as if the previous situation was just an illusion.

However, the entire valley also disappeared with the disappearance of the light mask at this time, and was replaced by a very ordinary and short peak, which did not look abrupt at all.

At this time, Ye Zhengtian and Zhu Lin, who had completed the arrangement of the formation and drove the formation, appeared outside the formation in a flash, seeing this situation, Luo Han and Qian Yifei also flew down from the mountain peaks where they were standing and came to the side of the two of them.

"Senior Brother Ye, Senior Sister Zhu, the strength of the two of you in the way of the formation is getting stronger and stronger, if you hadn't known this hidden formation beforehand, and watched the whole process from the layout to the completion of the drive from beginning to end, I'm afraid I wouldn't have noticed the existence of a hidden formation here!"

In fact, not only Qian Yifei, but even Luo Han, after the concealment formation in front of him was activated, he could only faintly have some strange fluctuations in the magic trick in front of him, but he believed that if he didn't know it, he would not be able to have such a formation close at hand.
