Xu Yuntian and Yan Xiaoyu walked towards the blue pyramid. They arrived next to the blue pyramid and saw a blue door at the bottom of the pyramid.

The blue door has words and patterns, and the pattern is a spiral pattern, like a vortex, looking dazzling.

"Uh! What pattern is this?" Xu Yuntian said in surprise.

"Brother Tian! This pattern looks dizzy!" Yan Xiaoyu frowned.

"Yes, this pattern is dazzling. It should be the password to open this door!" Xu Yuntian looked at the spiral patterns and said.

"Ah! Such a dazzling pattern would be a password?" Yan Xiaoyu said a little incredible.

Xu Yuntian kept staring at the pattern, and he tried to see some secret from the dazzling patterns.

He stared at the pattern for about three minutes, and suddenly he showed joy and lit his hand on the door a few times.

I saw those spiral patterns moving, and then the door released a ray of light, and with a slam, the door slowly opened.

"Oh! The door is open! Brother Tian, ​​how did you open this door?" Yan Xiaoyu looked at Xu Yuntian and said in surprise.

"Hehe! I stared at this pattern. After looking at it for a long time, I found that the pattern is actually composed of dots and lines. Although it is messy, it has rules to find."

"I found that there was an animal figure hidden in this spiral pattern. The two eyes of this animal are the secret to opening the door. So I pressed the eyes of the animal figure and the door opened." Xu Yuntian said with a smile.

Yan Xiaoyu said in surprise, "What! There are animal graphics hidden in this dazzling pattern? How can the animal graphics be seen?"

"Look carefully!" Xu Yuntian said with a smile.

Yan Xiaoyu stared at the pattern. He didn't see the hidden animal. He couldn't help but grab his scalp and said, "Brother Tian! I still didn't see anything?"

Xu Yuntian stretched out his hand and pointed at the pattern and said, "Look at these dots and lines, the pattern composed of these dots and dashed lines, from here to here, is it the shape of an animal?"

Yan Xiaoyu stared at Xu Yuntian's fingers. He finally understood and said in surprise, "Oh! I saw the shape of an animal! Damn! This pattern actually requires you to see the shape of an animal!"

This door is very thick, more than three meters away, and the ground is the road paved by the tears of angels.

Xu Yuntian and Yan Xiaoyu entered the pyramid through the three-meter-long path of angel tears. They were shocked by the scene in front of them.

"Wow! Mermaid!" Yan Xiaoyu exclaimed.

I saw that at the center of the pyramid was a diamond-shaped crystal-like thing, with a woman with blue hair standing there.

The woman was very beautiful, with blue eyes, and even her eyelashes. Her skin was snow-white and suffocating.

The reason why Yan Xiaoyu is called a mermaid is because the woman's whole body is soaked in the liquid. She has no feet, only a fish tail.

Xu Yuntian was very shocked. He circled around the diamond-shaped crystal-like container for a week. He found that the woman soaked in it was very strange, especially like the legendary mermaid.

But this woman is different from the legendary mermaid. It is said that the mermaid's tail has fish scales and also has scales on its body, but the woman's body is very smooth and has no scales.

Moreover, the woman's hair, eyes, eyelashes, and other hairs are all blue.

"Uh! Who is this? Why is this?" Xu Yuntian said in surprise.

"Brother Tian! This woman should be an alien, right?" Yan Xiaoyu turned her head and looked at Xu Yuntiandao.

"Aliens? Are there really aliens in this world?" Xu Yuntian frowned.

Yan Xiaoyu knocked on the crystal-like diamond container and said, "Brother Tian! Is this diamond container made of crystal?"

Xu Yuntian looked carefully at the material of the diamond container and shook his head and said, "This is not crystal, this is a material similar to crystal. This is the first time I have seen this material."

"Brother Tian! Is this woman alive or dead?" Yan Xiaoyu said.

"She had her eyes closed and she had no breathing, so she should have died." Xu Yuntian guessed.

"Uh! There is a mermaid's body in this diamond-shaped container. What's going on?" Yan Xiaoyu said in confusion.

Xu Yuntian shook his head and said, "It's really impossible to guess this. There is no text here. How did the mermaid's corpse appear here?"

"Brother Tian! Is this liquid soaking mermaid fu  er ma  lin?" Yan Xiaoyu said.

Xu Yuntian looked at the color of the liquid carefully, then shook his head and said, "This liquid is not the color of fu  er  ma  lin. The color of fu  er  ma  lin is colorless, but the liquid is slightly yellowed."

"Wow! This mermaid has been soaked here for thousands of years, right? It's lifelike, like a living person. It's so amazing." Yan Xiaoyu sighed.

Xu Yuntian nodded and said, "Yes! I didn't expect that there was such a thing in the cave of Xuantianyan, which was unimaginable!"

"Brother Tian! I think this mysterious heavenly rock should be left by an alien civilization. They arrived on Earth many years ago, and this should be one of their bases." Yan Xiaoyu said.

"Then how do you explain this mermaid? How do you explain the tears of those angels?" Xu Yuntian said with a smile.

"This mermaid may be an alien. This woman must have died of illness and was left here. Maybe she wanted to take the alien planet to heal her, but she had to leave her behind when she met an enemy." Yan Xiaoyu guessed.

"Haha! Little Fish, you're thinking too much. Maybe this mermaid was the human ancestor of the ocean at that time!" Xu Yuntian said with a smile.

"Brother Tian! How could human ancestors be like this? Didn't it mean that human ancestors evolved from apes?" Yan Xiaoyu said.

"What you said is also a guess. Some people say that humans evolved from marine humans. Maybe this woman is the earliest marine human being!" Xu Yuntian said with a smile.

Xu Yuntian and Yan Xiaoyu were chatting, and they were spinning around the diamond container, observing carefully, trying to find some clues from above.

Suddenly Xu Yuntian discovered that the bottom of the diamond container was touching the ground, and penetrated deep into the ground, and about half of the edges and corners of the diamond container were underground.

"The edges and corners of the diamond container are underground. Is there any mechanism underground?" Xu Yuntian said to himself.

As he said, he reached out to pluck the rocks on the ground. Suddenly, the diamond-shaped container lit up, like a light bulb.

Blue light appeared on the entire surface of the diamond container, blue patterns appeared on the surface, and strange texts.

"Oh! The diamond container has actually become brighter!" Yan Xiaoyu exclaimed.

"Uh! I seemed to have touched this diamond container switch just now!" Xu Yuntian said in surprise.

"Brother Tian! What is the blue pattern on it?" Yan Xiaoyu accused the blue pattern on the diamond container.

"I guess it should be the circuit pattern. I accidentally touched the switch just now, and the circuit diagram appeared." Xu Yuntiandao.

"Oh! Brother Tian! The mermaid opened her eyes!" Yan Xiaoyu exclaimed.
