I heard there's a ghost here

  "Is this a button?" Huang Yizhe took over the white handkerchief, looking at the pinkish-purple button in it, carefully examining it, and unexpectedly found that there were some words engraved on the surface of the button. Although the characters on it were somewhat blurry, they could still be vaguely made out, seemingly written as the character "yuan" (fate).

  Xiao Qi was asked in a hurry: "Little Seven, where did you find it? On Cai Fei's body?"

  "It's not actually on Cai Fei's body, anyway, it was after you left, I was examining her corpse, and later found on the ground," Ling Mo slightly furrowed his brow, "When we entered the crime scene together, we didn't see this button at all. I think this button must have fallen off from Cai Fei's body afterwards."

  "Did it fall from Cai Fei's body?" Huang Yi Zhe furrowed his brow, trying to recall the clothes Cai Fei was wearing earlier. It seemed like a purple ruffled shirt with white buttons.

  Worried about recalling incorrectly, Huang Yizhe hastily stretched out his hand towards Ling Moqi, "Little Qi, bring the camera."

  "Here," Ling Mo took the camera hanging around his neck and handed it to Huang Yizhe, "Yizhe, take a look yourself, that button is not from Cai Fei's clothes."

  Huang Yizhe's eyes were fixed on the image on the camera, but he didn't see the purple button on Cai Fei's body. He clearly saw that the buttons on it were white.

  "This button doesn't seem to be from Cai Fei's body." Huang Yi Zhe let out a small sigh, looking at the button in his handkerchief. "Then whose could it be?"

  "Could it be the murderer?"

  Huang Yizhe and Ling Moqi couldn't help but look at each other simultaneously, then withdrew their gaze. Since the case began, this was the first time they had such tacit understanding.

  "It must be so." Again, an unintentional chorus.

  Ling Mo couldn't help but purse his lips slightly, "I didn't think we two would have such a tacit understanding, it's rare."

  Huang Yizhe furrowed his brow, seeming somewhat displeased. "Xiao Qi, since you'd already discovered it, why didn't you say anything just now?"

  "Yi Zhe, do you think I was right to say that in that situation?" Ling Mo's voice was low and even. "Cai Fei's parents are already heartbroken over their daughter's death. If we tell them now, they might continue to make a fuss. After all, it's just a button, it doesn't prove anything. Let's wait until we have some progress before saying anything."

  "Uh, you're right, this button will appear at the scene of the crime, perhaps it's the evidence left by Cai Fei, and this button will be the clue to the whole case." Huang Yizhe looked far away with his eyes, meaningfully saying: "Since we've discovered such a powerful clue, we must continue to investigate."

  "Yi Zhe, although we have this button as a clue, how are we going to investigate? There are so many students in Sheng Xin High School, do we need to check every single one of them? And if this button is really left behind by the murderer, they must have destroyed that piece of clothing long ago, so how could..."

  Before Huang Yizhe finished speaking, he firmly said: "No, this at least proves that she didn't commit suicide, but was murdered. This is our greatest gain!"

  "Could it really be him? I'm worried..." Ling Mo Qi let out a faint sigh, looking somewhat lacking in confidence.

  "If we don't investigate further, we will never know the answer." Huang Yizhe rewrapped the pinkish-purple button and grasped it tightly in his hand. "Also, there are only five reasons for murder: one is greed, two is lust, three is love, four is revenge, and five is accidental killing. However, no matter which one, a condition must be met."

  "What conditions?" Ling Mo Qi asked hastily.

  "The killer and the victim must know each other, and their relationship won't be too shallow. Whether they are enemies or friends, it's all the same."
