It seemed to be a metal door, very stable, thick and black, Yao Yao reached out and touched it, cold, non-gold and non-iron, but a bit like jade-like slippery. After looking at it, Zhao Zihan was touching a slightly concave place with both hands, revealing a serious thinking expression.

"This is about the groove where the key is placed to open the door, we have the key, but this key is too old, I don't know if it is reliable?" After Zhao Zihan finished speaking, he raised his left hand, but he was suddenly stunned: the baby beeswax disappeared without a trace, leaving only a circle of gold threads, on which there were seven small black metal sheets neatly arranged......

After looking at it, his heart suddenly moved, and then he leaned closer to the door to take a closer look, and the depression was not exactly the same size as the circle of gold thread, and the seven shallow intaglinations in it were exactly the same as the seven small metal pieces. Hurriedly took it off, took the gold coil and put it in, pressed it firmly, and there was a "click" sound in my ears, and the door was slowly opened.

When I raised my eyes, I couldn't help but gasp, this door, that is a bit thick... I'm afraid it's not close to 80 centimeters? What kind of eerie place is this, if you go in, if this door is closed, how can you die?

Yan Mei'er's face was full of suspicion, and Yao Yao looked vigilant, whether to enter or not, this is a question...... Zhao Zihan looked over, and it seemed to be a long aisle, and at the end of the aisle, there was a sudden light.

Now that he has arrived here, there is no way out, so he can only move forward more head-on, thinking about it, Zhao Zihan did not hesitate anymore, and stepped in. When the two girls saw him walking inside without looking back, they also scrambled to follow, and after walking a hundred and ten steps, the aisle was at the end, and suddenly there was a bright light in front of them.

Yan Mei'er, who was walking at the back, stepped out of the aisle, and the aisle suddenly disappeared out of thin air, Yao Yao exclaimed in surprise: "Ah also~", but Zhao Zihan and Mei'er did not look very surprised. Zhao Zihan was even looking up at the sky.

After watching it for a while, he said something inexplicable: There are two trees behind my house, one is a jujube tree, and the other is still a jujube tree.

Mei'er smiled, but Yao Yao was taken aback, and looked around, the starry sky was dotted with ink, the fog was misty in the cold wind, and the twinkling starlight was staggered, illuminating the heavy mountains, and she was standing on the top of the snow peak...... Suddenly realized: it turned out that after a lot of hardships

After suffering a lot, I was frightened a lot, and I guessed the mystery, and this place inside was exactly the same as ...... outside!

Taken aback, she couldn't help blurting out: "Oh my God, how can this be?" After asking, she found that no one paid attention to her at all, and she felt a little strange in her heart, and couldn't help but look at Zhao Zihan and Mei'er's sister. Suddenly discovered: Both of them were generally obsessed with looking at the distant sky, as if they were stunned, Zhao Zihan even stretched his neck, like a male duck who was pinched and lifted up... What's wrong with them?

Zhao Zihan looked at the sky for a long time, coughed lightly, took out a ruler from the magic ring, looked at it carefully a few times, and said: "Strange, the stars in the sky and the changes in their positions are no different from those contained in the proverbs of the ancient holy mountain. In this way, is this a holy mountain, how is this possible? Doesn't it mean that the holy mountain is the highest peak in the world, and this mountain is as high as it is, how can it be like the highest peak in the world?"

Mei'er came over, glanced at Qi Su a few times, then looked at the sky, and asked, "This is the Big Dipper, right?" Zhao Zihan nodded lightly, and suddenly sighed, exclaiming: "This... This... How did the key in my hand become like this?"

Yao Yao hurriedly said: "No, right? We always have to go out, although the entrance to the cave is gone, but I guess when I go out, or there is a door somewhere, you need a key, right? What if I lose the key?"

He pulled Zhao Zihan's left hand and looked at it, and was suddenly a little dumbfounded: it turned out that there were seven metal pieces in a circle, but now there is only one slightly larger round piece hanging on the gold line, swaying... Two fingers pinched it, and it was like the size of a gold coin that the world had seen in a dream, with a faint pattern on it.

"What kind of pattern is this?" Mei'er saw it clearly on the side, and hurriedly asked, Yao Yao thought about it sideways, and replied, "Lilacs, but why lilacs?"

Zhao Zihan squinted his eyes and said, "You ask me, who do I ask?" Now, I finally understand what is going on, and I also know why that carving always took us around in circles before. ”

The two girls were a little puzzled, and asked one after another, Zhao Zihan pretended to look at this, and then at that, and then said slowly: "This place is indeed exactly the same as the outside, but don't you find any difference?"

The two girls suddenly tilted their heads in unison, looking thoughtful, and after a while, both of them seemed to understand, pointed to the stars in the sky, and said, "Ah, wow, last night, I didn't see any stars in the sky!"

Zhao Zihan didn't answer immediately, looking at the lines of the snow-capped mountains in front of him, experiencing the faint pain in his chest, he faintly had a layer of realization in his heart: for no reason, he suddenly saw more colors, more lines, and stars appeared in the sky. All this has changed, there is only about one explanation, we crossed that channel, something changed... Well, this place is about the same place as yesterday.

If I hadn't guessed, the density of the air in here would not be the same as yesterday, otherwise, how could I have such a feeling of pressure in my chest?

Is this the mystery of dimensional change?

Thinking of this, I don't sell it anymore, in the end, this picture of the holy mountain proverbs, I think more than the two girls, and I know a little more, so it's not worth showing off too much.

He took it for granted and said: "This is where we arrived yesterday, and it is also the place where the eagle keeps taking us around in circles, and the reason why the eagle takes us around in circles is because... We're going to climb a lot of mountains this time. Moreover, it is to climb the mountain with different air densities and reduced oxygen. ”

He pointed to the starlight in the sky with one hand and said firmly, "The infinite starlight is at the dangerous peak, do you see where the Big Dipper shines? ”

Following his fingers, Yao Yao and Mei'er suddenly gasped, far away in the sky, among the continuous snow peaks, there is the highest peak, am you afraid that it is hundreds of kilometers away?

Mei'er was not convinced, and pouted: "Not necessarily, don't be scary, if that's the case, why did that eagle keep wandering around here yesterday, why don't you just guide us there?"

Feeling a little stuffy in her chest, Yao Yao echoed: "Yes, yes, I'm tired today, and the cold wind is howling on the top of this mountain, let's find a place to adjust it first, and then talk about it tomorrow?"

About half an hour later, Yao Yao suddenly saw the place where the rabbit meat was roasted last night, Yao Yao stopped, and there were two soft sounds, and Mei'er and her sister and Zhao Zihan also fell to the ground.

A good night's sleep.
