However, Shen Yun is also very experienced now, so he immediately took out the green frost. The latter, as before, was immediately brilliant. The coercion seemed to have been unloaded in half. The rest, he gritted his teeth, and he could still bear it.

Seeing that the texture of the giant bone was so familiar, he secretly guessed in his heart: Could it be that I was in this huge skull just now?

So, I tried to gently poke the giant bone in front of me with Qingshuang.

Sure enough, the sound was crisp, like the sound of gold and stone colliding. It was the sound I heard when I tapped the stone wall with Qingshuang in a small space before.

How did I get into it before?

Recalling the scene at that time, Shen Yun only felt more and more incredible in his heart: it wouldn't be like this......

It's ridiculous, but he decided to give it a try.

Immediately grasped Qingshuang, pointed to the skull at the front end, and said word by word: "My name is Shen Yun, I have a lot of ...... when I first came here."

Before the word "criminal" was finished, the huge skull really moved!

It was like a mountain collapsing, and it whirred and pressed down.

Shen Yun didn't have time to think about it at all, he only felt that there was a flower in front of him, and the soles of his feet seemed to be stepping on a solid stone slab.

Ha, it's really back!

Seeing that the gray and white around him were as one, Shen Yun was excited-it turned out that with the Ice and Snow Secret Realm as an intermediary, plus saying his name, he could enter and exit here freely!

Before his body could stand still, his mind moved again, trying to enter the secret realm of ice and snow.

This time it was a failure!

He tried three times in succession, but he couldn't enter the ice and snow secret realm.

Why doesn't it work?

Shen Yun looked down at the flickering and flickering green frost, and felt that this was the reason.

So, he held the green frost in his hand again and began to slowly scratch across the stone wall.

At this time, he realized that the small space in front of him was actually not the previous one.

In addition to the fact that the material is the same, the height and size of the two are also similar, the same small, irregular shape, but after a closer look, it is easy to find that the ups and downs of the bone wall are not the same. With Shen Yun's memory, these differences were too easy to distinguish. Therefore, he was very sure that this was not the small space that he had before.

And it's not hard to figure out - what he saw outside was a huge skull comparable to a mountain. And as far as he knew, the bones were not stones. Whether it is a human bone or an animal bone, there will naturally be some pores in it. These small spaces are porosity. The skull is so big, and the pores in it are naturally very large.

This time it was good luck, after looking for a while, the green frost stopped flickering and became more translucent than when it was outside.

However, Shen Yun did not immediately try to enter the Ice and Snow Secret Realm, but took out a small piece of paper from the treasure bag and tried to stick it on the bone wall to mark the point.

As a result, after the small piece of paper was attached to the bone, as soon as he left his hand, it disappeared silently and quickly, like a large sea bowl that had been inadvertently knocked down outside.

Shen Yun was taken aback.

This is a new discovery.

Next, he deliberately took out some small things from the treasure bag.

None of them are exceptional. As soon as they got out of their hands, in the blink of an eye, they were all engulfed in bones.

Shen Yun didn't believe it at all, they hadn't been swallowed up before, it was all because of himself.

Thinking of the situation when he didn't take out the green frost outside, under the strong coercion, he almost fell down, and he thought: If it weren't for the green frost in my hand, would it have been swallowed?

Of course, I don't dare to risk it again.

Involuntarily tightened the Qingshuang in his hand again, for the sake of safety, he immediately took out a long strip of cloth from the treasure bag, and directly tied Qingshuang firmly in the palm of his right hand.

After tying a dead knot, his heart was finally at ease, and he let out a long breath of turbid air, and continued to scratch the bone wall with green frost.

As he expected, as soon as he left this point, Qingshuang returned to his previous flickering state.

Eventually, he found every inch of the small space. I found that there was only one point the size of a wine cup, which made the green frost stop flickering and emit a very bright blue light.

Next, he made the same attempt in the rest of the world, but he couldn't enter the Ice and Snow Realm.

Finally, Shen Yun stood back in front of that point, and gently pressed it against it with green frost again, his mind moved.

And it worked!

A flower in front of him, and in the next breath, he was already in the secret realm of ice and snow.

With another thought, he came out of the ice and snow secret realm, and he stood in front of the giant bone again.

Then, under the pressure of great coercion, he tried to enter the secret realm of ice and snow.

Failed.

In other words, in this strange place, he could only enter the Ice and Snow Secret Realm in a small space and pointed to the only place the size of a wine cup on the stone wall with Qingshuang.

Three more replicates were performed. Every time.

Shen Yun can be regarded as having figured out his first experience in this strange place.

There is more than one small space in the giant bone. At least so far, the small space he entered was not the same every time he entered.

Just, what's the use of these small spaces?

It was empty, and it blocked the "Sleeping Eye".

It didn't take long for Shen Yun to find the beauty of a small space.

As soon as the sun came out, bursts of white smoke rose from the yellow sand. The smoke was the same as when he first arrived, but not as thick for the time being. The blue light emitted by the green frost is still able to dispel the white mist. But under the sun, the power of cyanosis is obviously greatly reduced. So, soon, Shen Yun was caught in a thick fog. After a while, he was horrified to discover that these white mist were very corrosive. The blue muslin robe he wore had been carried in the fog for less than half an hour, and it was covered with holes of all sizes, and there was not a single finger of cloth.

His skin has been quenched repeatedly, and his strength is no less than that of a treasure-level magic weapon. In the fog, except for feeling slightly hot, there is no other discomfort for the time being.

Based on the feeling on the surface of his body, as well as the speed at which the green cloth robe was corroded, Shen Yun speculated that he would probably be able to carry it in the mist for two or three days.

After two or three days, his skin could no longer withstand the erosion of the mist. Thinking that the skin of his whole body would be corroded away like a green cloth robe, his whole body felt as if he had fallen into a thousand-year-old ice cave.

Therefore, this place must not be left for long. He had to find a way out as soon as possible.

And before that, he had to try to protect himself and not be hurt by the white fog.

During the day, when the sun comes out, white fog will emerge from the yellow sand, and it is obvious that you can't walk around. At this time, the small spaces where the fog can't get into them become excellent hiding places.

At night, the temperature drops sharply, and the white fog gradually ceases to emerge from the ground. The giant bone also has the effect of dispelling mist, and is stronger than Qingshuang (during the day, it can also dispel mist, but it can't dispel white fog from the ground, and it has no obvious effect). In the second half of the night, there will be no white mist within three zhang of the giant bone.

That is to say, when the white fog rises outside, he can only hide in a small space to avoid being hurt by the white fog.

In the second half of the night, the white fog withdrew and went three feet away. Then he will be able to come out. At that time, it also happened to be the time when the fog-repelling effect of green frost was the most powerful. With Qingshuang in his hand, he can break through even in the thick fog.
