Chengnan saw Zhang Mei nodded, then pulled up the window bolt in his hand, and then gently inserted the toothpick in his hand next to the window bolt, stuck the window bolt where it was, and then gently pushed the window on, only to hear a soft sound, the window had been closed, but the window bolt did not fall because it was stuck by the toothpick, after doing this, Chengnan walked back to the house from the outside, pointed to the window that had been closed, and said: "After the murderer climbed out of the window, just like me, he stuck the window bolt with a toothpick, so that the window bolt would not fall when it was closed." [Girl's favorite romance /d/a/s/h/u/b/a/o/cc] And the murderer deliberately enlarged the bolt hole so that under non-human control, the window bolt could fall smoothly into the bolt hole. ”

Zhang Mei also remembered that she seemed to see a toothpick on the table under the window that day, but she didn't expect that the toothpick that she didn't pay much attention to at the beginning was actually this function, but Zhang Mei was still very strange, because if you inferred from Chengnan, then this toothpick should be inserted on the window bolt, how could it fall on the table, so Zhang Mei wondered: "But according to what you said, shouldn't this toothpick be inserted into the deadbolt, and your toothpick is inserted on it to jam the bolt, and it stands to reason that the bolt can't fall into the bolt hole below."

Xiao Gang, who was on the side, frowned and said: "Could it be that the murderer escaped from the window and then gently knocked on the window, causing the toothpick to be shaken off, and then the window bolt fell, just falling on the window hole, so that the window would not be locked by itself?"

"That's right, it must be like this, only in this way can he create such an illusion of murder in a closed room" Xiao Gang felt more and more that his guess was right, and suddenly exclaimed excitedly.

Seongnam shook his head and smiled, "You knock on the window to see if the toothpick can fall off." ”

"I'll try"; Lin Wei, who was closest to the window, volunteered.

"Bang" Lin Wei said and raised his hand and knocked lightly on the window, but the toothpick did not move at all, and it was still stuck there diagonally.

"Bang bang" Lin Wei didn't believe that evil gravity knocked twice in a row, but the toothpick was still well inserted on it.

"You must have inserted it too tightly, and the murderer would definitely not have inserted it as tightly as you did," Xiao Gang shouted.

Seongnam smiled: "Then you go and try it." ”

"Okay, I'll plug it in," Xiao Gang said, and ran over to pull out the toothpick, and reinserted it himself. But the result was that either the insertion was too light, the toothpick fell off, or the window bolt fell off.

Chengnan saw that he had inserted more than a dozen times without success, and said with a smile: "No need to insert it, the strength of this toothpick should be just right so that it will not fall off, and it can jam the window bolt." ”
