Conan: I'm definitely a blackmailer!

"Look carefully, do those fish only have one eye?"

Conan asked, with a hint of urgency in his tone.

"Well... let me see..." Mitsuhiko used a flashlight to carefully illuminate the fish in the water.

"Ah! It really has only one eye! And the mouth is so big, and there are two long whiskers... This... Isn't this a catfish?"

"Catfish... catfish?!" Yuan Yefei's eyes lit up when he heard the word "catfish".

It was as if he saw a delicious catfish meal, "I like catfish the most!"

"Now is not the time to talk about this, Yuantai!"

Conan reminded helplessly, "We have more important things to do!"

"The eyes of the fish in this stream have not degenerated, which means that they have not always lived in the cave, and should have swam in from the river outside."

Xiao Ai squatted by the stream, carefully observing the fish in the water, and analyzed in a calm tone.

Ye Fei also squatted down, looked at the clear stream, and nodded:

"You are right, it seems that this stream is connected to the river outside."

"In this case, we just need to go against the direction of the water flow, and we should be able to find the exit."

Xiao Ai stood up and said with a firm look.

Ye Fei also stood up and was about to go upstream with Xiao Ai, but suddenly found that there seemed to be something reflecting on the ground.

He bent down to pick it up and saw that it was a pair of black-framed glasses.

"Isn't this...'..." Ye Fei recognized at a glance that the glasses belonged to Kudo Shinichi, that is, Conan.

His face suddenly became serious, "Oh no! Could Conan be lost?"

Xiao Ai also came over and looked at the glasses in Ye Fei's hand, frowning slightly:

"Why are these glasses here? Could it be..."

A terrible thought came to her mind, and Xiao Ai didn't dare to think about it anymore.

She quickly took out a small instrument from her pocket, turned on the switch, and aimed it at the glasses.

"This is..." Ye Fei looked at the instrument in Xiao Ai's hand, a little confused.

"This is a tracker I modified, which can track the special signal invented by Dr. Agasa."

Xiao Ai explained, her eyes fixed on the display screen on the instrument, her fingers operating quickly.

"Conan and several other children are carrying this signal transmitter. As long as they are nearby, their location can be tracked."

As Xiao Ai operated, a simple map appeared on the display screen on the instrument.

There were several red dots on it, which were the locations of Conan and his group.

"They are here!" Xiao Ai pointed to a red dot on the map and said.

"And they seem to have left something here..."

Ye Fei took a closer look and found that there were other red dots on the map besides those representing Conan and others. (To read the exciting novels, go to Faloo Novel Network!)

There are also several blue dots of light, distributed near the red dots.

"What are these blue dots of light?" Ye Fei asked.

"It should be the button-type transmitter invented by Dr. Agasa."

Xiao Ai explained, "These transmitters can send special signals to transmit information."

"Information? What information?" Ye Fei was even more confused.

Xiao Ai did not answer. She enlarged the scale of the map and carefully observed the arrangement of the blue dots of light.

"These buttons... seem to... form a shape..."

Xiao Ai muttered to herself, her fingers sliding on the screen to narrow the scope of the map.

"110?!" Ye Fei looked at the numbers displayed on the screen and shouted in surprise.

At the same time, on the other side of the cave, the robbers were in trouble.

"Damn! How come this road is blocked too?!"

The scarred man kicked the boulder blocking the road angrily, making a loud "bang" sound.

"Boss, what should we do now?"

The big-toothed robber asked, with a hint of panic in his tone.

"What else can we do? Go back (Wang Hao)! Chase from another road!" []

The mustache robber said viciously, his eyes full of revenge, "I don't believe that we can't catch those little devils this time!"

At this time, Conan and his party were facing greater despair.

"What should we do? There is no way forward!"

Mitsuhiko shone the flashlight ahead, his tone full of despair.

In front of them was a huge underground cave.

And where they were was a platform at the top of the cave.

The only exit was a waterfall pouring down from the edge of the platform, with a rapid flow and a height of more than two meters. .
