The big black hole is located in the center of the lake bottom.

On the surface, nothing unusual could be seen. Since it was night and there was only moonlight, it was pitch dark inside.

"It's unbelievable that a white bone can actually block this hole." Xu Bai touched his chin and said to himself.

Although it is unbelievable, in this world, it is normal. After all, not everything can be explained by the experience of previous lives.

"Would you like to go down and take a look now?" Qin Feng asked.

Ever since the big black hole appeared, Chu Yu had been hiding behind Xu Bai, sticking her head out and looking around. Until she saw the big black hole, she kept staring without moving away.

Qin Feng asked Xu Bai if he wanted to go down. Chu Yu finally reacted, gritted his teeth, and finally decided to express his inner thoughts.

"Master, I feel something is wrong here." Chu Yu hesitated, looking at Xu Bai's face and then turning to look at the big black hole.

Xu Bai originally planned to go down directly, but now after hearing what Chu Yu said, he frowned and turned his eyes to Chu Yu.

"What's wrong?"

Chu Yu's words just now made him a little confused.

In fact, Chu Yu has always been careless and extremely curious about everything, but now Chu Yu's behavior is completely opposite.

Why do you feel nervous looking at it?

It was pitch black all around. Under the moonlight, Chu Yu scratched his head and said confusedly: "How to describe it, I feel very disgusted and disgusted. When I look at this black hole, I feel uncomfortable all over."

While talking, Chu Yu also gestured.

Hearing Chu Yu's description, Xu Bai frowned.

Others don't know Chu Yu's identity, but he knows it clearly.

Chu Yu is the daughter of King Shengyou, in other words, she is also a member of the royal family.

Now Chu Yu was behaving unusually, which made Xu Bai unconsciously think of the royal family, especially the one in the capital.

But he still remembered the bet he made with King Shengyou.

If he solves the matter here, then the world is so big that the emperor will not interfere.

If it is not resolved, the emperor will fight with King Shengyou. As for what to fight, of course it will be him.

Sometimes Xu Bai wondered what he had done to attract the emperor's attention, but for the sake of his salted fish dream, he really couldn't give up.

What's more, if you win this matter, Yunlai Mansion will be in your hands, and there will be many benefits.

It was a good thing at first, but seeing Chu Yu's performance today, he had to think more about it.

Although the emperor was far away, distance could not measure his level of scheming.

Don't forget how the eighth prince died. He fell into the emperor's trap step by step and became the price of rescuing King Shengyou.

Will someone who can be an emperor be less resourceful?

The more he thought like this, the more cautious Xu Bai became.

But after repeated questioning, Chu Yu just repeated that he was extremely disgusted with this place, and there was nothing else besides that.

"Brother Xu, it's getting late." Seeing that Xu Bai had been in a daze, Yun Zihai couldn't help but remind him aloud.

They all heard what Chu Yu said, but they had no clues and could not guess.

Xu Bai came back to his senses, looked at the black hole in front of him, and said, "Let's go."

Although I have thought so much, I still have to look at the clues in front of me.

Several people no longer hesitated and jumped from the edge of the lake.

The bottom of the lake is wet and the soil is loose. Because the lake water has just been opened, it is very sticky when you step on it.

When Xu Bai and the others came closer, they could see the whole black hole clearly.

Under the illumination of the moonlight, the black hole finally became clear.

Inside the entrance of the cave is a staircase that slopes downward. Due to the narrow entrance of the cave, nothing deeper can be seen, and only the first few steps can be seen.

"There must be an independent space underground here, and there are also special stairs. It seems that someone built it, but I don't know who built it." Yun Zihai looked back and forth several times and said.

Of course Xu Bai also noticed it. He touched his chin, looked at Chu Yu and said, "Do you have any more feelings?"

Chu Yu stared at the stairs intently. After hearing Xu Bai's words, he shook his head: "It's the same as the beginning, I just feel annoyed here."

Indescribable irritability.

It’s more annoying than those few days of the month for women.

Chu Yu could feel that this irritability seemed to be an instinctive disgust, making her feel uncomfortable all over.

"You don't know the reason?" Xu Bai looked at Qin Feng and said, "You are his cousin, so you should know it."

Qin Feng also shook his head and said: "I don't feel disgusted, and my cousin has been here since she was born... and we haven't met a few times."

When Qin Feng was about to say that Chu Yu had been in the palace all along, he saw Yun Zihai here and held it back.

Xu Bai didn't get what he wanted, so he simply stopped asking, changed the subject, and said to Chu Yu: "If anything unusual happens later, you have to tell us as soon as possible."

Chu Yu nodded vigorously, indicating that he understood.

When everything was ready, everyone looked at each other and Yun Zihai was ready to lead the charge.

In this regard, Xu Bai didn't say anything.

The second one is Qin Feng, the third one is Chu Yu, and the last one is Xu Bai.

There are the strongest people guarding the front and rear, and Qin Feng and Chu Yu can respond in time in the second and third positions.

After all, this hole can only be entered by one person. If it were wider, it would be easier to arrange. Now we can only solve the problem with this optimal solution.

As for who is stronger between Yun Zihai and Qin Feng, Qin Feng directly raised his hand and said that he could not beat Yun Zihai.

In Xu Bai's opinion, whether this fight was a good fight or not is another matter. In fact, in the second position, he wanted to protect Chu Yu more.

When a few people walked into this narrow passage, the sticky lake feeling on the ground disappeared.

The passage is paved with stone slabs and is clean and tidy. Because it is at the bottom of the lake, there is a trace of moisture in the air.

The dark, narrow, and damp passage always makes Xu Bai think of other things.

The journey went smoothly. Yun Zihai led the way and played a very good role.

There was no light in this passage, but Yun Zihai waved his hand and wrote a few words. When he fell on the book in his left hand, the pages slowly floated up, glowing with hazy light, illuminating the place.

Xu Bai also took this opportunity to look at the surrounding situation.

The walls of the passage are smooth and delicate, and when touched with your hands, there is no rough feeling at all.

"Everything here seems to be carefully crafted, even the walls are exquisite." Xu Bai rubbed his chin with his hand and said.

Even an ordinary passage was full of exquisiteness. Xu Bai thought that the things inside must not be simple.

The further inside they go, the further away they are from the ground.

The stairs went down diagonally, and they were heading underground now.

Everyone didn't communicate much, and they all moved forward cautiously. After they walked for a while, something different finally appeared.

The surrounding walls were no longer smooth, but had undulations and protrusions of varying degrees. Xu Bai leaned against the wall and saw something fishy in it through the light from the book.

Different degrees of protrusions and undulations come together to slowly form a picture. The carvings painted on the wall are exquisite reliefs.

"I seem to have seen this thing somewhere before." Qin Feng looked at the picture above and fell into deep thought.

What the relief depicts is a scene of people coming and going. There are many people on it, doing different actions. In addition to people, there are various house shapes around, which look like

A picture of a prosperous age.

Like the walls, the reliefs are equally exquisite. The characters on the reliefs are painted with great detail, and their expressions are lifelike. They all have cheerful expressions and look very lively.

"Isn't this the street next to the government office?" Xu Bai said.

He finally figured out that what was carved on the wall was the street next to the Yunlai Mansion Office.

He passed by there often and had memorized many of them. Several of the landmark buildings looked exactly the same.

Not only that, but also the pedestrians, including the vendors calling to buy on both sides of the street, are all engraved on this relief.

"And here, this is another street." Yun Zihai pointed to the relief next to him and continued.

"This road seems to be the place I passed by when I was fishing before. I also bought a fishing rod in this shop." Qin Feng looked at another piece of relief and said.

Chu Yu wondered: "There is even a shop where I often sell steamed buns, but why are these reliefs carved in this passage?"

No one answered his question, because no one here understood the question. The scene in front of him was too weird. Without any clues, he could only watch it.

"Keep walking inside, maybe we will get an answer later." Xu Bai said.

Everyone nodded, knowing that just by staying here and watching, they wouldn't get any useful information, so they stopped staying and continued walking towards the depths.

The passage is dark, but there is light, which always makes people feel slightly comfortable.

The further they went inside, the more mysterious it seemed to them.
