Seeing that there was a layer of colorful smoke floating on the three waterholes, it undoubtedly frightened Xu Yan and Xiaocai not far away.

Previously, after Xiaocai's detailed analysis, Xu Yan had already learned that in these three waterholes, with the continuous progress of time, different colors of fog would be filled, and these fogs would continue to cover the south side until they stopped in the northern area of Dengbei Mountain.

So, thinking of this, Xu Yan immediately calculated the time in his heart, and then came up with an answer, it should have long passed the time of floating mist, but what is the phenomenon in front of him?

Xu Yan couldn't help but ask Xiao Cai: "What the hell is going on, didn't you say that its last kind of fog is the red mist, what is this gorgeous colored mist?"

Hearing Xu Yan's inquiry, Xiao Cai, who had already quietly spread out his perception, hesitated for a moment, but replied with some confidence: "This ...... I haven't seen this situation either, it seems that we can't get by, or let's go back, and when you cultivate enough to fly with a sword, we'll walk from the air again. ”

Hearing this kind of bastard thing from his naturally war-fearing spirit pet, Xu Yan immediately cried and laughed, and scolded with a smile: "Hugh has to say such useless stupid words, let me cultivate in this valley to the sixth floor, then I have to cultivate until the Year of the Monkey and the Moon?" ”

After getting along for a while, Xiaocai also got to know some of Xu Yan's character, and knew that he was the kind of fearless person who would never back down after making up his mind, no matter what difficulties he faced. Therefore, although it was a little reluctant, in the end there was no way but to obediently do what he was told.

However, a moment later, she suddenly sighed.

When Xu Yan heard this surprise, his face grim and asked, "What's the matter?"

When Xiaocai heard his question, she repeatedly confirmed the floating colored mist, and then replied: "Those mists are not poisonous. ”

When Xu Yan got this reply, he couldn't help frowning, but he couldn't help but think of a sentence recorded in the "Classic of Mountains and Seas of Five States" in his mind, "Everything in the world, whether it is heaven and earth, beasts, or mountains, rivers, plants and trees, the more colorful things are, the more poisonous they are enveloped, the stronger the poison they are carrying." Therefore, after hesitating for a moment, he asked Xiaocai again, "Are you sure?"

"Well, I've sensed it three times, and it really doesn't have any toxicity. ”

After getting the final confirmation, Xu Yan exhaled softly, but in those eyes as deep as an ancient well, he did not relax at all, he turned his head to look at Cai Zhenjing, and said to her: "You just wait here, I'll go to the three pools in front of me to have a look." ”

When Cai Zhenjing heard this, her face was a little hesitant, and she replied, "Otherwise, I'll ...... I'll go with you. ”

Xu Yan shook his head slowly, and replied in a solemn tone: "No, I'll just go by myself, and you can stay here to have a response." ”

Without waiting for Cai Zhenjing to say anything more, Xu Yan had already walked towards Sanjing Creek.

"Xu Yan, I can't see it, sometimes you are quite kind-hearted, if it is according to some people, I guess I would like to let her go to explore the way. Seeing that Xu Yan refused Cai Zhenjing's request to go with him, Xiaocai couldn't help but quip.

Xu Yan really can't refute Xiaocai's statement, there are thousands of personalities in the world, and he is just one of them.

He doesn't use Cai Zhenjing as his pathfinder, it doesn't mean that others don't do it, it's like Zhou Xian, who is quite unscrupulous in order to achieve his goals, or Yan Ziyi, who is born very cautious and is used to calculating the dead people around him, presumably when faced with this situation, they will first use their subordinates to investigate.

But then again, even if they do this, in terms of Xu Yan's own values, they will not be beaten to death with a stick in the coffin, saying that they are wrong to do so, or that they are the annihilation of human nature.

In his eyes, those who want to achieve great things must first live before they can achieve great things, and any right and wrong in the world must be judged according to the environment at the time, as well as different positions and angles, and things in the world can never just be considered right in collective morality, that is, right.

When Xu Yan approached the top of the three pools, which was about ten zhang away, he slowed down, because even if Xiao Cai had confirmed that these fogs did not carry any toxicity, in the end, this was the Mitsui River, which was known as the 'Little Forbidden Land', and its reputation was not overnight, but for decades, and there were many elders-level figures from the major sects, who were lost in it.

"Xu Yan, do you really have to go and check, it's too late to withdraw now...... If you get sucked in later, it will be difficult to get out again. ”

Xu Yan turned a deaf ear to Xiao Cai's reminder at this moment, when things came to this point, it was impossible for him to retreat, but only to move forward, otherwise he could only wait until he held back a sword path cultivation in the valley to reach the six-story realm, or a martial arts cultivation to reach the seventh grade. But in such an empty valley, and the aura of heaven and earth is not very strong, it is impossible to reach that realm step by step and little by little, without more than ten or twenty years.

Of course, if he could often pick some wild fruits that would help improve his cultivation, or hunt some middle-level spirit beasts' inner pills to swallow, he would be able to speed up a lot of cultivation, but that kind of cultivation method would be the same as the Colorful Sky Devouring Python, which was not the result Xu Yan wanted.

"Xiaocai, do you remember how you got into these three waterholes in the first place, and how did you escape?" Xu Yan ignored Xiaocai's previous persuasion, but asked about its experience.

Seeing him so 'obsessed', Xiaocai could only sigh helplessly in the end, and then, after thinking about it for a while, she replied in a quiet tone: "At that time...... To be precise, it should have been thirty years ago, when I had just entered the fifth-level spirit beast, and it was from the upper reaches of this evil stream that I continued to swim south, but when I approached the topmost waterhole in front of me, I wanted to swim over its water, but when my snake head had just touched the waterhole, a huge suction force appeared inside, sucking me in. ”

"And after that?"

"After that, I went to a place full of heaven and earth spirit treasures, wow, there is not underwater at all, there is everything, like a hundred years old golden hairpin stone orchid, vermilion bird fruit, thousand-year-level transformation grass, everything, hey, but when I wanted to swallow one of the heaven and earth spirit treasures in one bite, I suddenly thought that I had just entered the fifth-level spirit beast at that time, and the foundation was still too unstable, and I couldn't continue to swallow those heaven and earth spirit treasures so quickly, so I was ready to cultivate in place for a while, and then swallow those delicacies after my cultivation was stable, anyway, they wouldn't run away on their own feet。 ”

"Did you succeed then?"

"No, because I can't feel the slightest heaven and earth aura in it, and you know, without heaven and earth aura, I can't stabilize my cultivation, so I thought, since there is no heaven and earth aura here, why can so many heaven and earth spirit treasures grow?"

"Why?"

"I don't know, I still haven't figured out why, and since I was thinking about this, I was squeezed out of that space by some other force, and then, I saw a lot of spirit beasts, all running wildly in one direction, I hesitated for a while, and then ran with them. ”

Seeing that Xiaocai fell silent, Xu Yan asked, "In the end, you escaped from the waterhole without realizing it?"

Xiaocai sighed and replied: "Yes, this is very strange, right? But let me tell you, when I escaped, I could feel that in that passage, there was actually a very terrifying aura, that aura was much stronger than me at that time, and in the process of escaping, I seemed to see invisibly, there was a huge eyeball staring at me to escape, and then I thought about it carefully, the aura that made me feel frightened should have emanated from that eyeball." ”

"Eyeballs? What kind of eyeballs?"

"Hmm...... How to say it, to say that it is an eyeball, in fact, is not accurate, because its volume is too large, it looks more like a huge sphere, the whole is transparent, if you don't look very closely, it is difficult to detect its existence, I also found this in a trance, so I'm not sure, but that's all I know. ”

Hearing Xiaocai's bizarre and unbelievable experience, Xu Yan, who was only about three feet away from the waterhole at this moment, finally stopped, because as long as he took another step forward, he would be contaminated by these colorful mist.

He stopped to take a look at the strange pool in front of him, which had no ripples or waves, and then threw out a stone in his hand that he had picked up from the stream.

"Click"!

The stone only made a soft noise in the pool, and it disappeared without even the slightest stirring of water.

Seeing this treacherous scene, Xu Yan frowned again, it seems that this waterhole is not a waterhole at all, but like a quagmire, he raised his steps and moved a step forward gently, the waterhole still had no reaction, but when his body and head completely entered these floating colored fogs, and took a breath, he felt that in this fog, there was a strange fragrance, and then, but before he could figure out why this was the fragrance, his whole person appeared in a trance.

An incomparably huge fierce beast suddenly appeared in front of Xu Yan, it was like a huge dragon from ancient times, but it did not grow horns, but compared to the real dragon, its body seemed to be more fat, but it was such a behemoth that was not even recorded in the "Classic of Mountains and Seas of Five States", but at this moment, it had already opened its bloody mouth and bit Xu Yan.

Seeing the huge blood mouth in front of him, which was as deep as a cave, was biting him frantically, Xu Yan's eyes were extremely indifferent, but he didn't have the slightest intention of avoiding and resisting.

After a while, the giant mouth bit down as he wished, and carried an incomparably violent air current, as if it was about to swallow Xu Yan into his belly, but then, Xu Yan's eyes appeared black again, and when he regained clarity, how could there be any trace of the giant beast in front of him?

"It's a mist that can make people hallucinate? Xu Yan sneered and said to himself.

"Did you just see something, Xu Yan, I just touched these fogs, and I actually saw my natural enemy, and it was the kind of Hundred Shadow Sparrow that had grown to the peak realm, ...... It really scared me to death, I thought I was going to be eaten. ”

Hearing that Xiao Cai's reaction was almost the same as his own, Xu Yan did not feel the slightest surprise, but was more sure of his own opinion, but he was very curious in his heart, why did these three strange waterholes create such a fog without any substantial harm? Is it just to let people, or the spirit beasts in the mountains, not get close to it?

Xu Yan fell into deep thought, and his mind couldn't help but look back on the countless years he had experienced, and then when he thought of a divine beast, his heart was suddenly shocked, "Could it be that they are the same kind of creatures? But the grade of that creature, even among the many ancient divine beasts, is definitely an existence that belongs to the first order, and it should not be possible to appear in the Heavenly Domain of this level." ”

Xu Yan's face suddenly became very ugly, and he didn't dare to think about it further, because he couldn't imagine that if there was really the body of that creature in the three waterholes in front of him, then when it grew up, what it would bring to the people of the Five States Continent.

Perhaps, only perdition?

"No, I'll have to go inside the waterhole and see what it is. After thinking about it for a while, Xu Yan still said seriously to Xiaocai. Without waiting for Xiaocai to answer, he continued: "If you really don't want to go down, I won't force you, I can leave your body outside the pool, and by the way, you can also help take care of Miss Cai." ”

Xiaocai was originally a hundred reluctant to enter this waterhole again, but now after hearing Xu Yan's words, for some reason, she wanted to follow the other party into it. So, after a long battle between heaven and man in her own thoughts, she finally made up her mind and said, "I...... I'd better go in with you, I've been in once before, and maybe I can help you with something. ”

When Xu Yan heard her say this, he couldn't help but smile slightly on his very dignified face, and joked in the tone of a cardinal: "Yo, did you suddenly eat the gall of a bear's heart and a leopard, and you are even willing to take the initiative to go down this waterhole with me?"

When Xiaocai heard that he still had an air conditioner to mock himself, he immediately said angrily: "Whether you go down or not, if you don't get down, I'll change my mind." ”

Xu Yan smiled at this, but no longer teased her, and replied directly: "Down, go now." ”

As he spoke, he had come to the waterhole completely, and then he leaned out slightly to check what was under the waterhole, but then he found that except for his own shadow reflected on the water, there was only clear water under the water, and there was no bottom at all.

"Whew!"

Xu Yan exhaled a breath of turbid breath heavily, and the next situation he had to face was completely bottomless, so even he would feel a little short of breath about it, but in the end, after he exhaled this turbid breath and strengthened himself, he no longer hesitated, and then jumped directly to the center of this waterhole.

"Whoa!"

As his body jumped into the pool, it was finally the pool that set off a wave of water ripples, but only a few ripples were blurred, and when his whole body was completely submerged in the pool, the water surface quickly returned to calm, as if nothing had happened.

Cai Zhenjing, who was nearly thirty feet away, saw this scene, her face turned white instantly, and she thought in her heart, "Didn't he say that he just went to the waterhole to take a look, why did he suddenly jump down?" However, Xu Yan, who was already in the waterhole, couldn't give her an answer after all.

After jumping into the waterhole, they did not appear to be sucked by any force as Xiao Cai said before, and at the same time, they did not go to the space where there were heaven and earth spirit treasures everywhere, but just jumped into the ocean, only a steady stream of clear water.

Xu Yan used the turtle breath method, and after diving down this waterhole for nearly thirty zhang, he finally couldn't help but ask Xiaocai: "No, this is simply an ordinary waterhole that can't be ordinary anymore, there is nothing unusual about it at all, it's nothing more than that its depth has no bottom line, but how can there be any strange space?

When Xiaocai heard Xu Yan's words, she also didn't find anything peculiar, and immediately replied with some embarrassment: "Eh...... Impossible, although I did hallucinate in the fog of color before, the experience of thirty years ago was by no means a picture of my own imagination. ”

"Then why haven't we encountered anything after so long of diving?"

"This ...... I guess we haven't dived deep enough, so why don't we dive a little deeper? If we still haven't found anything strange after a hundred feet, then we can swim out again. ”

Xu Yan saw that Xiaocai was a little unreliable, and his face immediately turned dark, but then, according to Xiaocai's suggestion, he continued to dive down.

However, as they went deeper and deeper into the waterhole, and when they reached a depth of about fifty feet, they found that from this position, the waterhole had completely lost its light, not even the slightest light, as if it had entered the middle of the night in the new moon phase.

So, Xu Yan could only take out the night pearl from the storage bag and illuminate the dark pool.

I have to say that the role of this night pearl is really omnipotent, not only can it be used on land, but also in deep water, but when they really sneaked into about 100 zhang, but still didn't find anything, Xu Yan finally retreated.

He said to Xiaocai Chuanyin: "It seems that there is really nothing here, the only strange thing may be that this waterhole is too deep, it is almost certainly a bottomless pit, and it does not seem to be connected to the other two waterholes, since we have dived for hundreds of feet and found nothing, if we continue like this, it will only be a waste of time, let's go back directly." ”

Xiaocai had no objection to this, so she replied: "Well, then let's go back." ”

Xu Yan saw that Xiao Cai had no opinion, so he turned around and wanted to swim up, but when he turned around, only the faint light emitted by the night pearl in his hand suddenly burst out of an incomparably bright light.

Xu Yan and Xiao Cai felt this sudden scene, and their hearts were instantly horrified, when they looked in the direction of the light source at the same time, and then they saw that a huge eye as Xiao Cai said before, Huo Ran slowly opened it from the lower side of them.
