Cheng Yu spent two days refining the Dust Shelter Pill, and looking at the crystal clear Dust Shelter Pill in his hand, he was very satisfied.

Just thinking of that strange lake, he didn't know if this dust pill was really useful. But anyway, he's going to give it a try.

When everyone followed Cheng Yu and stood by the lake again, everyone was very nervous.

"Senior Brother Yu, is this dust avoidance pill really useful?" Xin Luo looked at the pill in Cheng Yu's hand and said with some expectation.

"I don't know, but I have to try it anyway!" Cheng Yu was also a little nervous.

Logically speaking, there are three most terrifying things about this lake, one is that there is a very strong attraction in this lake, and all objects that enter the lake will soon be pulled under the lake.

The other thing is that it can absorb aura, and the reason why monks are able to fly is because they can use aura. But if the lake sucks away his aura, even if the lake doesn't have such a terrifying attraction, they will fall into the lake.

The last point is the strange temperature of this lake, with the temperature of the water, even if it all boils, it is impossible to burn a master of the merger period like them.

Of course, part of the reason they were burned was that the lake water had absorbed their aura, and there was no way for them to use it to resist the boiling water.

However, this is only one of the reasons, because his strength is there. Their current physical bodies are extremely powerful, and under normal circumstances, ordinary boiling water would not be able to hurt them like this.

Another important reason is that the water of the lake is stranger than they imagined, and the temperature is not high for them, but it is extremely terrifying, which is really strange.

Now Cheng Yu has a way to avoid dust, that is, after swallowing this elixir, a faint protective layer will form outside his body. This protective layer can completely isolate them from the outside world.

In this case, then there would be no way for the strange lake to suck their aura, and they would be able to continue flying.

Of course, this is only an ideal hypothesis, and whether it is really possible to overcome this strange lake is only known after experimenting with it.

"Then let me try!" said Xinluo with great interest.

And the heart on the side is not at all afraid to be this urgent pioneer, the experience of the past few days has made him have a constant fear of this lake, he is really once bitten by a snake, ten years afraid of the well rope.

"No, my idea is that I hope you can enter the mountains and rivers map first, and then I will experiment with it myself. If it's over, we'll just go over together!" Cheng Yu shook his head and said.

Although the dust pill in his hand was enough for everyone to take, he was not worried about so many people passing together. Because this lake is indeed a bit scary, if one is not handled well, the chances of so many people in the situation are also greater.

If it's just him, it's much easier, and if it's not right, he can just go back. If you can pass it, then everyone will be happy.

"That's not good, in case you find something unexpected, is there anyone to help you, it's too unsafe!" Xinhe said uneasily.

"Yes, how can we all rest assured if we are alone?" Lin Yuhan said while holding Cheng Yu's hand.

"Then you guys watch from the side first, I'll try it first!" Seeing that everyone was not at ease with themselves, Cheng Yu could only retreat and try the water alone.

"That's okay, if it's really okay, it's not too late for us to enter the Mountains and Rivers Map!" everyone nodded.

Cheng Yu walked to the edge of the lake and swallowed a dust pill, and everyone obviously saw that there was an extra layer of transparent retention layer outside Cheng Yu's body, although it was colorless, but some eyebrows could be seen.

Seeing that Cheng Yu was about to take the first step, everyone's hearts tightened to their throats.

Everyone believed that in front of such a strange lake, there must be some treasure on the opposite side of the giant peak, otherwise how could such a terrifying lake appear to protect it?

So, no matter how dangerous this lake is, they have to break through it.

Cheng Yu suddenly rose into the air and slowly floated towards the lake.

However, even if Cheng Yu had already prepared, when the whole person entered the sky above the lake, he felt a force that I don't know if it was an extremely strong pull or pressure, and it still made him down all of a sudden.

However, Cheng Yu didn't seem to have adapted to this process for a while, and the whole person just sank down a meter away, still standing in mid-air, and did not touch the lake.

Everyone was shocked, but when they saw Cheng Yu finally stabilize his body again, their chests suddenly relaxed.

I saw that Cheng Yu seemed to be somewhat accustomed to this power, gritted his teeth and slowly floated up. However, seeing Cheng Yu's appearance, it can be seen that this strange power is indeed very powerful, otherwise Cheng Yu's strength would not be so uncomfortable.

However, Cheng Yu's experiment did not end here, but began to slowly move towards the lake.

However, as Cheng Yu continued to move towards the center of the lake, he felt that this power was getting stronger and stronger. He had tried his best to keep his body from sinking. But he still can't resist this force, and the whole person is always sinking in the process of advancing.

And when Cheng Yu walked out of the distance of two feet, his whole body was almost less than half a meter away from the surface of the lake.

Everyone was sweating, and the lake was almost a hundred zhang away, and it was already like this when it was more than two zhang away. I'm afraid that before I even reached the center of the lake, the whole person had already sunk into the water.

"No, you can't get over it like this!" Xinmei shook her head and said.

If I'm not mistaken, the farther he goes to the middle of the lake, the more attractive he becomes. Judging from the current situation, he will be able to touch the lake at most if he walks a distance of one kilometer!" said Xinhe with a frown.

"Senior Brother Yu, come back!" Xinluo shouted.

Cheng Yu gritted his teeth and wanted to move on, but seeing that he had only walked for a tenth of the way now, and the distance on the other side of the lake did not seem to have shortened, he also knew that it would not work like this.

There was no way, Cheng Yu could only choose to return in the end!

However, it was much easier to return, and the strange power was visibly weakening, and the distance from the lake was easily raised again.

It took about a pillar of incense to get back in the past, but it was only a matter of three or two clicks when I came back.

"Senior Brother Yu, how do you feel, is there any hope?" As soon as Cheng Yu returned to the shore, Xinluo asked impatiently.

Although Cheng Yu's experiment this time obviously failed, he also had to listen to Cheng Yu's feelings to know if there was any hope of success.

"It's strange, there is an extremely powerful pulling force above this lake, the more you go to the center of the lake, the stronger the force, I have worked hard to overcome it, but I still failed!" Cheng Yu said helplessly!
