After Li Xiaoyao dived under the lake, he found that the lake water that looked clear above now looked very muddy.

Looking up and looking down, it was two scenes, and he found that the visibility below was no more than three meters.

But fortunately, there is still Shennian, although the lake water is also turbid under Shennian, but at least it is not like when it is above, and nothing can be seen in the green area.

Crash.

Li Xiaoyao swam towards the center of the lake, and he found that the lake was very deep, because he was swimming diagonally, but after half an hour of swimming, he still did not see the bottom of the lake.

At his speed, he swam at least 100 meters in half an hour, and although it was diagonally facing down, it was enough to show that the depth of this lake was at least 100 meters.

Continuing downstream, Li Xiaoyao felt even more strange as he went deeper and deeper, because he hadn't even touched a living creature along the way.

Not to mention fish, even some small microorganisms are not seen, because they are divine thoughts, so as long as there are signs of life, they can be detected.

This made Li Xiaoyao more and more cautious, this place was full of weirdness, which was enough to show that there was probably some unknown danger under the lake.

......

After about a quarter of an hour, Li Xiaoyao finally saw the bottom of the lake, only to see that the bottom of the lake was slightly flat, and it was densely covered with mud and sand.

There are some aquatic plants of different colors growing in the mud and sand, as well as some other unknown plants.

In his mind, the plants looked vibrant, and the bottom of the lake seemed to be normal.

Li Xiaoyao floated two or three feet from the bottom of the lake and began to wander, surveying everything around him.

The bottom of the lake looks empty, and there is nothing to be seen except for the accumulation of sediment and various aquatic plants.

Li Xiaoyao estimated that his position at the moment should be some distance from the very center of the lake.

"If you go to the center, you might get something. Li Xiaoyao swam towards the center of the lake from memory, wanting to see if there would be any danger there.

Normally, a martial artist in the foundation realm can dive for two quarters of an hour, and if it is a water attribute martial artist, it may be longer.

And with the strength of Yi Li's spiritual power, he can dive for about half an hour, and he has been diving for less than two quarters of an hour since he dived, so there is still plenty of time.

It didn't take long for him to approach the center of the lake, and at this moment, Li Xiaoyao's divine mind also noticed something unusual.

"That's?"

He actually saw that there were some bones mixed in the mud and sand at the bottom of the lake, and Bai Sensen's bones were at the bottom of the cold and cold lake, and there was a kind of eerie feeling at first glance.

Fortunately, Li Xiaoyao has a lot of experience, if he is replaced by an ordinary martial artist, he will be scared to pee.

There are many bones, scattered in the mud and sand at the bottom of the lake, and some have even been covered by the mud and sand, so it is difficult to see clearly

The bones are large and small, most of them are animals, birds, beasts, and... Fish, and fish bones are also the most numerous.

When he saw this, Li Xiaoyao knew in his heart, no wonder there were no fish creatures in the lake, it seemed that they should have been eaten by everything.

"Is there some monster at the bottom of the lake?"

When he thought of this, his back felt a chill, and he felt the urge to swim up immediately, after all, if it was so, it would be a little scary.

"Wait, this is?"

Li Xiaoyao suddenly saw a special skeleton, the familiar shape was obviously a human skeleton.

Looking at the luster of the bones, it should have just died, and Shen Nian swept around again, and he found that there was more than one humanoid skeleton.

When he saw this, the doubts in Li Xiaoyao's heart gradually became clear, so the previous screams should have been made by the owners of these bones before their deaths.

"They must have been eaten by some kind of creature at the bottom of the lake?" Li Xiaoyao speculated in his mind.

Shen Nian swept around more carefully, and at the same time he was on guard, ready to slip away as soon as there was any danger.

"This must be the center of the lake. Li Xiaoyao said in his heart, and then his divine thoughts spread out in all directions.

Previously, in order to save his physical strength, he only released one-third of the power of his divine thoughts, after all, if his divine thoughts were fully opened, it would be very hurtful.

At this moment, all the divine thoughts spread out, and everything within a radius of more than thirty meters could be seen clearly.

Immediately, Li Xiaoyao saw a strange scene, only to see a certain place at the bottom of the lake, not far from him, just where the divine thoughts could reach.

A huge black shadow appeared in his thoughts, and in order to see more clearly, Li Xiaoyao swam towards the position of the black shadow.

A moment later, he came not far from the black shadow, and immediately saw a shocking scene.

I saw that at the bottom of the lake in front of me, there was a huge portal, which was 100 meters high, and it was densely covered with mossy plants.

If you look closely, you can see that the color of the gate itself seems to be green, and it seems to be made of bronze.

The giant gate is full of potholes, which seem to have been soaked in the lake water for a long time, and some rust can be seen, and blue-green rust can be seen in some places.

"Could it be that behind the giant gate is the real burial ground of the powerhouse of the Sky Realm?" Li Xiaoyao guessed in his heart.

Crash.

Li Xiaoyao's body swam, wanting to get close to the bronze giant gate to take a closer look, to see if he could see any clues.

Waves, waves.

The sound of water waves sounded, Li Xiaoyao reached out and touched the bronze giant door, his hand was cold, there was a metallic texture, very rough.

He then made a detour to the back of the giant gate to check, and found that the back of the giant gate was no different from an ordinary gate, and there was also green moss growing on it.

Li Xiaoyao Shennian carefully investigated, and immediately found that there were also formation patterns flowing on the giant gate, if he guessed correctly, this giant gate was very likely to be the eye of the sixth-order formation.

Then Li Xiaoyao came to the front of the giant gate again, and his body began to swim upstream, wanting to see what was going on above.

After all, normally speaking, the keyhole of the door is usually in the center of the door, so he wants to see if there is any difference in the center.

Soon Li Xiaoyao came to the center of the giant gate, although he didn't see anything like the keyhole.

But he saw that in one of the giant gates, there was a depression in it, and Li Xiaoyao touched it with his hand, which looked like a groove.

The grooves are boxy and a foot deep, and at the bottom of the grooves are intricate patterns that are an inch deep, as if anything can be inserted to match these lines to open the door.

"Is this so difficult to open the keyhole of the door?" Li Xiaoyao guessed in his heart.

"Wait, this groove...... How do you feel like you've seen it somewhere. Li Xiaoyao suddenly noticed the size of this groove, and he seemed to have seen it somewhere.

Wave......

Just when Li Xiaoyao was ready to reminisce, he suddenly heard a small fluctuation coming from above the giant gate.

Raising his head and sweeping away, his expression suddenly changed wildly, and a huge monster in his mind was silently attacking him.

Feeling the terrifying aura emanating from the monster, without saying a word, Li Xiaoyao's body quickly fled and swam towards the surface of the lake.
