They looked at each other in astonishment...... They had speculated that the shoe prints might have been left by the murderer, but the soles in front of them completely overturned their suspicions.

Gu Yunfei took the sole, looked at it over and over, and said dumbfounded: "This is not a sole for wearing, but like a big seal." ”

Luo Fei said: "How can there be such a big seal? ”

Gu Yunfei stretched out his hand that had been stained with black things from the sole of his shoe to Luo Fei, and said, "There seems to be something black ink on the sole." ”

Luo Fei looked at his hands, which were also stained with black things, and looked at the soles of his shoes, there were also things like ink.

They carefully looked at the shoe prints on the ground and determined that the shoe prints were not stepped on by a person, but pressed by something like mud on the sole of the mold.

Gu Yunfei was puzzled: "What does this mean?" It's getting more and more fun to make stamps with size 44 soles. ”

Luo Fei said cautiously: "Maybe it's not a seal, could it be a symbol of some organization." A lot of strange organizations like to make a sign that they think is sacred. For example, the Axe Gang, an underworld organization, people in the organization will carry an ax every day and tattoo the axe on their body."

Gu Yunfei said: "What kind of organization do you mean Yang Biao is, could it be that he is from some kind of shoe gang?" So he has a sole. It's hilarious, what kind of organization would call itself the Shoe Gang. ”

Gu Yunfei laughed out loud because she had such an imagination.

"Maybe some people have unique tastes, or maybe shoes have an extraordinary meaning to that organization," said Roffy. Yang Biao's ashes have never been collected, and he should be an orphan, so no relatives have heard of his death. Only people who don't have a home will go to some strange organization to find their support. ”

Gu Yunfei said: "Hmm...... Yang Biao may be a person from some organization, violated some discipline, or became a traitor, and sent people to kill him internally. Yang Biao seems to be poor, not wealthy, and we can conclude that he was not a thief or a robber. We have determined that the person who killed Yang Biao came prepared, and the origin of this person finally has some basis, what organization should this murderer come from. ”

Luo Fei said: "--Organizations related to this sole. ”

Gu Yunfei said: "I will go back to the police station to check whether the files stored in our bureau have any organizations related to the soles of shoes, and see if the murderer shot Yang Biao, which means that the organization where the murderer is located is more evil, and there will definitely be any case records left in the police station." ”

Luo Fei took a closer look at the soles of his shoes and found that there was a five-digit number on the heel, which was obviously not the marked shoe size. He showed it to Gu Yunfei, but she didn't understand what it meant.

Luo Fei walked around the living room, balcony and bathroom, and found no more valuable things left by the murderer. He walked slowly to the bedroom, opened the wardrobe and took a look, there was nothing else hanging in it, except for a few spring and autumn clothes.

Luo Fei turned around and opened the curtain, held the curtain with his right hand and looked into the distance, then moved to the left, held the curtain with his left hand, and looked down, thinking about what kind of evil hand pushed her down from the 22nd floor.

Suddenly, he felt a hard thing in the place where he held the curtain in his left hand, and he looked at it casually, and it turned out to be a small hole, and the edge of the hole did not look like it was cut by a sharp weapon such as a knife, but it looked like a hole that had been burned, and the edge of the hole was rough, could it be a cigarette butt? But no, cigarette butts don't leave such a big hole, this hole is about 8 centimeters in diameter. And it is obvious that the entrance to the cave has not been burned for a long time.
