Seeing that a new passage seemed to be opened above, Conan decided to climb up.

This is an upward slope, but the surface of the slope is not smooth.

If you are an adult, due to your weight, it is still difficult to use limited friction to resist the slope, and you must borrow tools.

But Conan is a child. As long as the friction force remains basically unchanged, it is still possible to climb the slope without using tools.

He took a position under the stone wall, crawling on the slope like a spider, trying to spread his weight as much as possible.

Climb up the slope for about ten meters and you will reach a vertical passage, about two meters high.

Unless you are Spider-Man, there is really no way to climb up.

There was no other way. Conan used his two feet and one hand as a fulcrum. With his free hand, he used a watch-shaped flashlight to shine upward, trying to see what was above.

The light spread out in the darkness above the head, which seemed to be a stone enclosed space.

The space above your head and the underground maze are connected by a mechanical trap door. If you step on it blindly, you will fall down.

Conan glanced at the open trap doors on the left and right again, and then discovered that there was a glass bottle stuck to the top of one of the doors.

There is something dark inside the glass bottle.

Conan moved to the side of the bottle in a crawling position, grabbed the bottle, and stood on the slope with the help of the extremely solid glass bottle.

He unscrewed the plug on it, and inside was a cone-shaped black stone, which seemed to have been placed here intentionally.

"black crystal?"

The light was not very good, and Conan couldn't clearly tell what type it was, but it was a kind of stone with a slightly cool texture.

He put the black crystal into his pocket, scanned it around again and found nothing else. As soon as he let go of his hand, he stepped on the slope and slid down the slope very quietly.

"Conan! How about it? Is there any treasure up there?"

The three little ones immediately gathered around expectantly, but Conan shook his head with certainty.

"This shouldn't be a place to hide treasure. I only found this thing..."

Conan took the black crystal out of his pocket, looked carefully under the light of the flashlight, and found that it was no ordinary crystal.

On the surface of the crystal, there is also a small patch of gloomy green.

But even so, this thing isn't worth much, it's probably just artificial crystal.

"Oh, why is this happening?"

"It took you so long and all your work was in vain?"

When they heard that it was not a treasure, Mitsuhiko and Genta were immediately discouraged like rubber balls.

Conan looked at the black crystal in his hand, frowned, and secretly thought about the reason.

Suddenly, his eyes lit up.

Maybe the hard work is not in vain...

"Mitsuhiko, do you remember the puzzle? Say it again and let me hear it."

"Wait a minute, let me look for it..." Mitsuhiko took out a small notebook from his pocket and read: "When the horns on the cow's head disappear and the tail becomes the head, the angels will come from the sky..."

"stop!"

Conan suddenly shouted stop, with an excited expression on his face.

"That's it, I understand!"

"I understand the meaning of the puzzle..."

As one of the two brains of the Young Detective Team, Conan took Mitsuhiko's notebook and wrote a big word "cow" on it with a pen.

"Actually, 'the horns on the cow's head disappear' refers to the Chinese character 'cow'. If you remove this part, it becomes 'noon'."

"In the Chinese zodiac, 'Wu' represents the 'Wuma', which symbolizes the direction of due south, and the time is the noon hour of noon."

Conan compared it with the "treasure map" and said: "Judging from the direction indicated on the treasure road, we should be south of the Angel's Pavilion now, most likely under the Angel of the South."

"I guess the space above can be opened at 12 noon. Enter it and get this black crystal, which is the first part of the puzzle..."

Qin Zhibo, who was standing on the other side of the rock wall, was listening to Conan's reasoning and knew that it was absolutely correct.

Although Conan didn't expect the linkage between Chinese character decryption and the Chinese zodiac at the first time, his ability to use the inversion of answers to deduce questions is not bad.

Let Conan get the fake Panest fragment, and he will be half successful.

The next step is to let Mr. Clock get the fragments at the right time without harming the young boy.

…

On the way back to the East Hall, Conan passed by the human skeleton and carefully inspected it.

However, the result was still the same, nothing was found to prove the identity.

Without investigation results, we can only return to the ground, wait for the police to come, and slowly check the previous missing persons to find out the identity of the deceased.

As soon as the group got out of the fireplace, Ayumi came over and asked.

"Conan, what should we do next?"

Haibara Ai also asked with great trust: "Edogawa, you have solved the next riddle, right?"

"Yes."

Conan nodded seriously, but then changed the topic, "But now there are still 5 hours before the end of time, and it is no longer possible to find the treasure."

"Why?" the three little ones said in unison.

Just as Conan was about to explain to a few people, the door to the room suddenly opened, and a figure stood directly at the door.

It's Mr. Clock.

The young detective team all trembled, like bad kids who did bad things and were caught by adults.

"Everyone, why are you here?"

The man in a gray suit stood at the door. After he finished speaking, he slowly walked into the room. The surface of his dark sunglasses reflected everyone's faces.

The handsome face under the sunglasses was expressionless, but gave people a strange sense of fear.

"We are solving a mystery. We just found it inside..."

Yuantai was about to explain to Mr. Clock what they had just gained, but Conan blocked Yuantai's words with a big hand.

"We wanted to find some clues about the puzzle below, but we found nothing~"

Conan smiles innocently, and his cosplay skills as a primary school student are already perfect.

But Mr. Clock just stood there quietly, looking at everyone expressionlessly, and did not respond to Conan's words.

After a moment, he took a half step forward, and Conan subconsciously reached out to protect the three little ones behind him.

Mr. Clock saw Conan's obviously defensive behavior and did not go any further. Instead, he slowly turned around on the spot and turned his face to several people.

"Lunch is ready, it's time to go back and eat..."

After saying that, Mr. Clock left from the door.

Seeing Mr. Clock leave, Conan put down his arm to protect everyone behind him, but his eyes were still sternly staring at Mr. Clock's leaving back.

Conan has always considered himself to be very discerning when it comes to looking at people.

For example, before and after eucalyptus, Conan can often detect the person who may be the murderer by observing a person's micro-expressions.

This is similar to a detective's intuition, and Conan's intuition is often more accurate.

But facing this "Mr. Clock", there wasn't much Conan could see through.

This person used many disguises on his body, including the code name "Mr. Clock", sunglasses that he never took off, never showing a meaningful expression, and a complete "poker face".

It is this inability to see through that makes detectives like Conan, who are good at seeing through people's minds, subconsciously be more vigilant.

But from the level of evidence, he still cannot fully prove that Mr. Clock is a bad person.

At this time, Mitsuhiko, who was standing behind, said, "Don't you think the clothes on Mr. Chong's body are very similar to those on the skeleton?"

"That being said, it seems so." Ayumi was not sure.

Conan recalled that the clothes worn by the underground skeleton were a gray suit. Although it was very worn, it was indeed similar to the clothes worn by Mr. Clock.

But what does this mean?

After thinking about it for a while, Conan decided to go back to the North Hall for dinner first and then think about the next countermeasures.

…

Returning to the Kitanokan where they live, the boy detective team started to have lunch.

Although he was a little unhappy just now, Conan was not worried that Mr. Clock would tamper with the food.

Because no matter whether the clock is a good guy or a bad guy, for whatever reason, he and others need to solve the puzzle first and find the treasure left by Yun Seikawa Gozo.

In other words, as long as the puzzle remains unsolved, everyone is safe.

After lunch, Yuanta was still not full.
