Xu Xingkong roughly guessed what Lin Xiaofeng was doing, she wanted to confirm that what she saw in front of her was not an illusion, if what she saw in front of her was an illusion, then everyone present would see different hallucinations because of the difference in the strength of the primordial spirit, but the result was a little surprising, everyone saw the same.

Is it possible to conclude that the qiē in front of us is not an illusion, but a real existence? But how can we explain that all the instruments have failed to capture this strange scene?

Also, why is what we have seen different from what we see today?

All kinds of questions can't be explained, but the spreading water ripples will not stop there, the boundary of the water ripples is continuing to advance towards the location of everyone, in fact, now the water ripples cover a considerable range, almost occupying the entire frontal line of sight of everyone, there is a feeling of overwhelmingness, looking at the heart will unconsciously give birth to a fear of being swallowed by this strange water ripple.

Xu Xingkong could hear everyone's faster and faster breathing in his ears, and even heard Lin Xiaotong's faster and faster heartbeat, to be honest, Xu Xingkong was also a little afraid in his heart, even in the face of powerful demons, Xu Xingkong felt that he would not be so uneasy, sure enough, it was still unknown that was the most frightening.

"Otherwise, let's get out of the way. ”

Xie Zhiqiang and the others didn't dare to speak, Xu Xingkong didn't have so many concerns, what he needed to prioritize now was Lin Xiaotong and his own safety, so he directly proposed to Lin Xiaofeng to retreat.

Xie Zhiqiang did not continue to disdain Xu Xingkong this time, but looked at Lin Xiaofeng with anticipation, as a leader, he must also consider the safety of his subordinates.

Lin Xiaofeng paused, turned his head to look at Xu Xingkong, and looked at his sister's face that was trying to hide her panic for a while, before he spoke:

"You guys stand back first and keep a safe distance, Xie Zhiqiang, you only need to leave two people here, and the others leave immediately. ”

Xie Zhiqiang was stunned, and then immediately asked, "Uncle Lin, what about you?"

Xu Xingkong was a little surprised by the title 'Uncle Lin' blurted out by Xie Zhiqiang, but he was more concerned about Lin Xiaofeng's decision, what did this guy want to do?

Lin Xiaofeng straightened up, looked at the water ripples that were spreading over, and said, "Execute, Xu Xingkong, protect my sister." ”

"Don't, Xiao Feng, you can't take any chances!"

Lin Xiaotong objected loudly before Xu Xingkong, his tone was extremely stern, but his voice was a little trembling, his eyes were flustered and looked at Xu Xingkong expectantly.

When Xu Xingkong heard this, he nodded vigorously and persuaded:

"Miss Lin, I think Xiaotong is right, now we don't need to take risks at all, we are not capable enough to solve this problem, we can find someone with stronger ability, now this thing does not cause substantial danger, does it?"

Lin Xiaofeng seemed to think about it seriously, and finally shook his head and said: "It's not my style to retreat when I'm in trouble, I want to see what this ghost thing is!"

Xu Xingkong was stunned for a moment, then shook his head helplessly, when Lin Xiaofeng raised this matter to the level of the state of mind, he knew that it was useless to say anything, if it was placed in the past, Xu Xingkong would definitely not be impressed by Lin Xiaofeng's seemingly stupid choice, but now Xu Xingkong has already understood a little that cultivators are not only cultivating the body and the primordial spirit, but more importantly, the mind.

But Lin Xiaotong didn't think so, she took a few steps forward, grabbed Lin Xiaofeng's left hand, and dragged it back without saying a word.

However, Lin Xiaofeng is a cultivator, and Lin Xiaotong is just an ordinary person, let alone a Lin Xiaotong, Xu Xingkong suspects that even if there are ten or eight more, he may not be able to pull Lin Xiaofeng.

Lin Xiaotong couldn't help but burst into tears when she saw that she couldn't pull her sister, and her voice was a little out of tune because of nervousness: "Why are you always so stubborn, I beg you, don't joke about your own life, okay, sister begs you?!"

Lin Xiaofeng's eyes when he looked at his sister suddenly changed, and the gentleness of that moment made Xu Xingkong feel like he couldn't breathe, as if something was hitting his heart violently, making him want to cry sourly.

"Sister, I'm not joking, let alone gambling with you, not just now, but never, but you don't understand, we people have no room to retreat since the day they set foot on this road, and if I retreat here today, it will be difficult to have the courage to move forward in the future, do you want your sister to become a coward, a waste?"

Lin Xiaotong was stunned for a moment, then shook his head violently and said: "I don't care, I don't care, I just want you to be good, I don't care about the rest!"

Lin Xiaofeng was not annoyed by Lin Xiaotong's rogue behavior, on the contrary, she smiled so softly, patted her sister's hand gently, and Lin Xiaofeng looked up at Xu Xingkong.

"Xu Xingkong, you should understand me, you help me take care of her. ”

As soon as Lin Xiaofeng's words fell, Lin Xiaotong's body suddenly softened, Lin Xiaofeng reached out and gently supported his sister's body, but his eyes kept looking at Xu Xingkong, Xu Xingkong sighed slightly, for Lin Xiaofeng's decision, Xu Xingkong really didn't know what to say, and he also had a little bit of self-blame in his heart, if he could see through the strange phenomenon in front of him, Lin Xiaofeng would not have to take such a risk.

Xu Xingkong didn't say anything, stepped forward and gently picked up Lin Xiaotong, Lin Xiaotong who had fallen asleep was soft, lying in Xu Xingkong's arms like a child, there were still tears in the corners of his eyes, looking so helpless.

Xu Xingkong hugged Lin Xiaotong and silently turned around and walked back, Xie Zhiqiang and the others hesitated for a moment, and then turned around and retreated, about ten meters back, Xu Xingkong turned around and stopped, Xie Zhiqiang and the slightly older companion stayed, and the others were sent away by him.

Four people, three pairs of eyes were staring at Lin Xiaofeng, as well as the strange water pattern that was still firmly expanding, Xu Xingkong felt that the expansion of the water pattern seemed to be a little slower, but this may just be his illusion and wish.

Xu Xingkong found that Lin Xiaotong's body was actually very light, and it didn't feel hard to hold it like this, or maybe Xu Xingkong's body had changed unconsciously, or his attention was completely focused on Lin Xiaofeng now, and he couldn't feel Lin Xiaotong's weight at all.

Xu Xingkong did put all his mind into the real vision, in fact, he didn't know what the effect of doing this was, but according to his rather limited experience, it seems that the more concentrated his attention, the more comfortable he will be in controlling his ability, Xu Xingkong can't help Lin Xiaofeng at all now, the only thing he can do is to go all out to observe, to oppress his potential, hoping that the real vision can be exerted extraordinarily, and he can see through the strange phenomenon in front of him.

Within the scope of what can be seen by real vision, the activity of the Yuan Spirit has indeed increased, and the color and texture seem to be changing, but according to Xu Xingkong's experience, this kind of enhancement of Cheng dù is still within the scope of normality.

The so-called normal category is completely defined by Xu Xingkong himself, Xu Xingkong has seen many formations, including the two formations he has personally experienced, as well as several large and small formations he has seen in the first hospital, so he can roughly determine that if you want to use the operation of the primordial spirit to change the rules in the local area, or be able to affect the biological primordial spirit in a certain range, the strength and density of the primordial spirit must exceed a certain critical point.

At present, there is no way to accurately define this critical point Xu Xingkong, but he can at least use the weakest formation he has ever seen as a reference to achieve a basic qualitative process, and the strength of the Yuan Spirit circulating in front of him is still quite far from this hypothetical 'critical point', but it is similar to the strength of the Yuan Spirit that naturally exists in some daily environments.

Of course, this situation was originally the reason that plagued Xu Xingkong and Lin Xiaofeng, obviously there was an extraordinary strange phenomenon happening in front of him, but the Yuan Spirit fluctuations closely related to the abnormal phenomenon were so weak, even if Xu Xingkong was relatively lacking in common sense, it could be seen that this was really not in line with common sense.

Perhaps, the problem is not with the Yuan Ling related to the formation, Xu Xingkong frowned and thought, but just now Lin Xiaofeng had already ruled out the possibility of general hallucinations, and basically ruled out the possibility of substantial changes in the wall, so the only thing left was

Xu Xingkong glanced at Lin Xiaofeng and saw that she was adding the necessary means of protection to herself, at this moment the three swimming green dragons had appeared around her body, and the pale golden halo around her head was becoming more and more luster, obviously, she used some means to strengthen the protection of the Yuan Shen, it seems that she also made a similar guess to Xu Xingkong, thinking that it may be something more powerful and can directly affect the Yuan Shen through the senses.

In fact, the thing that directly affects the Yuan Shen is still a form of Yuan Ling fluctuations, but unfortunately, Xu Xingkong's mutated real vision happens to be unable to see this Yuan Ling fluctuation, which is also the reason why Xu Xingkong was attacked by the mirage last time and was not discovered in time (the mirage itself has Yuan Ling fluctuations and can be captured by Xu Xingkong's real vision), as for why he can't see the Yuan Spirit fluctuations that directly affect the Yuan Shen, Xu Xingkong can't explain it, he can only think that his real vision is still defective, or he is not proficient in using it, or it is something else。

In fact, it is not difficult to understand that human vision, hearing, and even other senses will have a perceptual range, such as visible light that can only see red light to violet wavelength, infrared light with a longer wavelength than red light, and ultraviolet light with a shorter wavelength than violet light is invisible to the human eye. The same is true for hearing, which can only hear 20 to 20,000 hertz, beyond which the human ear cannot hear.

Obviously, Xu Xingkong's mutated true vision also has a perceptual range limit, and the fluctuation of the Yuan Spirit, which directly affects the Yuan Shen, seems to be just outside this range.

But is it absolutely impossible to detect light, sound, etc., that exceed the limits of the human senses? Of course not, in fact, the range that humans can detect is much larger than the range that human senses perceive directly!

So, is there a way to make yourself able to see those invisible Yuan Spirit fluctuations?

Xu Xingkong's gaze turned to the instruments on the table, if only he carefully asked about the usefulness of those instruments just now, maybe it would be helpful, but it seemed that it was not too late.

"Can Team Leader Xie ask you a few questions?"

Xie Zhiqiang was stunned when he heard this, although his face was unhappy, but he tried his best to suppress his feelings.

"As long as it's not unrelated, you ask. ”
