Mimicking the direction of movement of the fish, this allows Yun Tian to blend in with the fish, and can hide his whereabouts as much as possible. After about twenty kilometers of swimming, the lake in front of me became deeper and deeper, and its color gradually changed from light to dark black, and the dark black lake was like a terrifying mouth, as if it could swallow people at any time.

At this time, Yun Tian was also a little nervous, because he didn't dare to release too much spiritual sense, which also made his spiritual sense detection unable to know the situation ahead very clearly and accurately, of course, if there was an abnormality within a short distance ahead, he could still detect it.

As we continued to go deeper into the inner lake, the surrounding light became darker and darker, and later, except for a faint light above my head, it was almost pitch black and I couldn't see my fingers. Fortunately, Yuntian can still use a small amount of spiritual sense to investigate, avoiding the embarrassing incident of directly colliding with the fish on the bottom.

At present, Yun Tian has dived to a depth of nearly one hundred and sixty or seventy meters under the water, and the water pressure has become very large, but for a martial cultivator, it is still within the tolerance range of his body.

At this depth, the number of fish does not decrease but increases, but it is not those common fish, but some are very rare, and even some fish that can be used in medicine according to the Dan book.

Yun Tian was overjoyed when he saw this, there was a lack of all kinds of species in his sea knowledge space, how could he miss such an opportunity?

So he quietly opened a hole in the sea knowledge space, and the water of Suyue Lake surged in, directly filling the lake in the sea knowledge space.

At this time, the sea space is quite huge, even if the entire Suyue Lake is swallowed, but of course Yuntian will not do this, after all, there are already many sects and forces in the area of Suyue Lake at the moment, if there is a change here, it will definitely arouse the vigilance of others.

Of course, it is not a problem to collect a small amount of different aquatic animals, so Yun Tian rushed all the way forward, and at the same time did not stop searching for the resources in Suyue Lake.

Because Yun Tian is all the way down a certain slope slowly, so a few kilometers further, his depth has reached more than two hundred meters, to this depth, the light on the lake is no longer visible, Yun Tian is completely relying on the weak spiritual sense released by himself to identify the direction, at this time his spiritual sense has vaguely felt a faint energy throbbing in front of him, and at the same time, his body can also feel that the water flow seems to become rapid, but the surrounding water flow does not seem to be flowing in a fixed direction, on the contrary, it seems to be a little disordered。

This phenomenon made Yun Tian feel a little strange, but he still didn't pay much attention to it, after all, he was also mixed in with the fish now, and his tracks should not be so easy to expose. But when Yun Tian swam forward for a few hundred meters, the surrounding water suddenly became turbulent, and the surrounding fish also desperately fled backwards like crazy, Yun Tian was a little puzzled, but at this time, he couldn't just retreat without doing anything, so Yun Tian just cheered up twelve points, but the direction of his movement was still forward.

After walking forward for more than a hundred meters, Yun Tian finally realized what was going on here, right now the water flow around him was so rapid that it was difficult to stabilize his body, even with his cultivation in the Ning Yuan Realm, he could barely control the balance, at this time, the water flow around him was like being swept into a big grinding disc, constantly rotating at high speed, it turned out that this was a huge whirlpool at the bottom of the lake!

At this point, some of the weaker fish were no longer able to struggle, and they were all swept straight into the depths of the whirlpool. Yun Tian could have escaped in time, but the spiritual consciousness released told him that it seemed that there was a strong energy fluctuation in the depths of that whirlpool, and except for the depths of this whirlpool, the rest of the place was extremely calm, that is, maybe the answer he was looking for was in that whirlpool.

Therefore, Yun Tian had no other choice but to take a deep breath and go directly into the depths of the whirlpool.

This whirlpool is too huge, under its high-speed rotation, it is too difficult to control the balance of his body, and Yun Tian doesn't want to expend too much energy in this regard, so he just maintains a certain balance, and then follows the direction of the current, along a spiral trajectory, and gradually dives underwater.

Some distance down, the speed of this whirlpool became more and more turbulent, and Yun Tian almost lost his way in the high-speed rotation of the water, but fortunately, he was able to lock on to the increasingly strong energy fluctuations below, and he had placed a few true qi in the lakeside village on the shore of Suyue Lake and the place where the old demon tree was active as the basis for identifying the direction, which allowed Yun Tian to accurately locate his position.

When the speed of the water flow reached the extreme, and the trajectory of the downward movement became more and more straight, Yun Tian knew that this was to the vortex center of the whirlpool, and when he arrived here, there would be a vertical fall process, so Yun Tian hurriedly took a deep breath and made certain preparations, that is, the moment he inhaled in one breath, he felt that his body suddenly volleyed into the air, and then fell straight down with all the forces around him!

Yun Tian didn't dare to release his true qi to maintain his balance, but suddenly spread out a pair of wings, and with a pair of wings, he flew in that dark space.

Of course, at this time, Yun Tian's flying skills were quite perfect, so in this dark space, he was still able to maintain his balance and slowly fall towards the center of the vortex at a certain speed.

The speed at which Yun Tian fell was not fast, but when he fell to a certain height, there was a sudden burst of extremely strong pulling force below, Yun Tian's wings fluttered, and he had to try to fly upward, he wanted to maintain his balance, and try to stay in a safe place as much as possible, who expected that his attempt was as if he had been recognized, the strange power did not weaken at all, but became more intense, at this time Yun Tian also felt that there were several spiritual senses sweeping in the distance, his heart froze, and he quickly retracted his breath, and let the pulling force drag him down。

Falling all the way down, but without encountering the water flow, Yun Tian could see that the huge whirlpool formed by the water flow around him was like a huge water wall, wrapping the surroundings impermeable, and this water wall that went straight up and down just formed a stage of chimney-shaped space in the middle, Yun Tian also suddenly woke up, and the pulling force may not have been discovered by someone, but the air convection formed by this straight cylindrical space.
