"Filmed, right?" Meng Wu glanced at Zheng Hanfei, who was taking pictures with his mobile phone, and asked out loud, "If it's good, I'm going to start, by the way, when you use your tricks in a while, you can watch from the house, and when the door is locked, you can open it from the inside." ”

"No problem." Zheng Hanfei made an ok gesture, the smile on his face became thicker and thicker, judging from the place where Mengwu asked him to take pictures with his mobile phone, he completely understood what Mengwu's method was, although he was not sure that what he thought was exactly the same as Mengwu, but he was sure that the method he thought of would definitely make this room a secret room.

"Okay, then I'll say it." Holding the long thread in both hands, Meng Wu began to reason, "First, tie a piece of thread to the strip lock on the inside of the door and tie it into a slipknot, but the slipknot is in the middle of the thread, so that there is a long enough thread on both sides of the slipknot to pass through the gap between the bottom of the door and the ground. ”

While talking, Meng Wu showed Zheng Hanfei according to his method, in this regard, Zheng Hanfei became more and more sure that his idea was the same method as Meng Wu's, but this was just the beginning, it was too early to say that it was exactly the same, so Zheng Hanfei did not make a sound, and quietly continued to watch Meng Wu's next moves.

"Then, pick up the second fine yarn and arrange it the same way you just did, so that there will be four threads." Meng Wu held the four fine hairs formed by the slipknot in his hand, and said to Zheng Hanfei, "For the sake of convenience, I will call the part of the first thin thread that will not untie the slipknot as the No. 1 thin line, and the part that will untie the first thin line of the slipknot will become the No. 2 thin line, and so on." ”

Zheng Hanfei nodded, indicating that he understood very well. He knew that Mengwu did this completely out of scruples that he didn't understand, but Mengwu didn't want to think about it, who was Zheng Hanfei? Although the winner of the secret competition between the two this time was Mengwu, Zheng Hanfei didn't pay attention to the secret room from the beginning, if he and Mengwu were on the same starting line, it was uncertain who would lose and who would win.

After that, I closed the door and pulled the No. 1 wire in the hallway, and after pulling the No. 1 line, I pulled the No. 3 line, and the angle was not the same. This is repeated several times and the strip door lock rotates, locking the door in the house and forming a secret room. Meng Wu pulled two thin lines diagonally and shouted through the door, "Zheng Hanfei, look at it!" ”

Really! Zheng Hanfei, who was in the house, saw two thin lines swimming back and forth, and the strip door lock slowly rotated, and then with a click, the door was locked. In this regard, Zheng Hanfei sighed in his heart, exactly the same as I thought, because the direct pull may not be reversed as expected, because it must be in a certain direction, generally counterclockwise, so when pulling, it must be pulled diagonally, and the general angle must be estimated.

As for the murderer, it should have been done many times to calculate the angle, no, if the murderer is not stupid, it is not a problem to calculate it. Zheng Hanfei pinched his chin and thought to himself, but pulling back and forth like this, there was the key evidence to crack this technique, probably the murderer himself didn't expect that the door frame of this door was protruding in some places, which was extremely sharp, and some cotton wool would be scraped off when the fine wool passed through which places, but fortunately the fine wool would not be broken because of this, otherwise this technique could be seen through at a glance, and for the murderer, this was probably a blessing in misfortune.

Bang bang bang! The knock on the door interrupted Zheng Hanfei's thinking, and at this time he found that the fine wool tied to the strip door lock had disappeared, which means that Meng Wu had successfully completed this technique, so he turned the door lock and opened the door, and then Meng Wu walked in with a smile on his face, Zheng Hanfei could only shake his head helplessly, not knowing what to say.

"I didn't expect it to be the same as I thought." Zheng Hanfei said slowly, "After the door is locked, pull the No. 2 and No. 3 thin wires to untie the knot and pull back the thin wires for recycling, right?" ”

"Yes." Meng Wu nodded, "But it's a pity that there are fine yarns in the warehouse, and the warehouse is never locked, everyone on the second floor can do it, so there is no way to lock the suspect from the technique, and the true face of the murderer is still in the fog." ”

"I can only put this problem aside for the time being." Who the murderer was, Zheng Hanfei didn't have a clue, so he had to shrug his shoulders and said: "But no matter how you cover it up, the murderer will always show his fox tail one day, now we had better pay close attention to these suspects, and once we find something, we will follow the vine and reveal the identity of the murderer." I always feel like this is not over yet......"

"Let's go back to our rooms." The two returned to their rooms, and then Zheng Hanfei said to everyone in the room, "Don't leave without permission." ”

"Since you say that, does that mean you don't know who the killer is?" Zhong Ming didn't leave, but stood there and said, "Isn't this what it looks like?" ”

Hearing this, everyone stopped, and their eyes turned to Zheng Hanfei and Meng Wu, although they had already guessed some, but they still wanted to hear Zheng Hanfei and Meng Wu say the answer in person.

The two didn't speak, but judging from their nods, there was no doubt that Zhong Ming's words were correct, therefore, Zhong Ming and Niu Zhen's eyes showed disdain, but Zhong Xian's eyes showed a trace of fear, it seemed that the affirmation of the two made him turn the suspect to the mermaid again, as for the eyes of those who were familiar with Zheng Hanfei and Mengwu, they really couldn't think of why the two didn't find the murderer, could it be that this murderer was smarter than the two of them?

"I don't think you'd better play detective games because of 'half a police assistant.'" Zhong Ming sarcastically mocked the two before leaving, "This kind of thing, leaving it to the police is the most correct choice, and handing it over to you is purely time-consuming!" ”

"Satoru, what's going on?" After all the irrelevant people walked out of the house, Mo Gang walked in front of Meng Wu and frowned, he always felt that Meng Wu's ability was more than this, but the disappointed expression on Meng Wu's face told him that Meng Wu really didn't know who the murderer was, and Mo Gang subconsciously thought that Meng Wu's expression was not pretending.

"Who the murderer is, I really don't know!" Meng Wu said, "But I have solved the mystery of the secret room, Captain Mo Gang, you also know that I will not reason until the murderer is found, and this matter can only be left here for the time being." ”

Speaking of which, Meng Wu was a little troubled, but there were only so many clues, and he couldn't solve who the murderer was for a while, he could only listen to Zheng Hanfei's opinion, but this feeling, Meng Wu was a little unbearable, if it wasn't for luring the murderer to show the fox's tail, Meng Wu believed that he would definitely make a move to analyze who the murderer was all day and all night, and only his body couldn't bear it at that time, as for who the murderer was, most of the results were still unknown.

At the same time, Zheng Hanfei also accepted the inquiries of their group, and Zheng Hanfei had to tell them everything that happened.

"What are you going to do?" Qu Menghan asked with concern, "I don't allow you to do things that hurt your body!" ”

"You know me so well!" Zheng Hanfei smiled bitterly, "In addition to this method, there is only one word: wait!" These days, Meng Wu and I go out for a walk, looking for the remnants and mermaid treasures, and Ling Hua has to seriously investigate, remember, it is a serious investigation, not pretending to seriously investigate this case, as for Menghan, Xiao Xun and Di Luo, let's see if there is anything abnormal in the others. ”

"There is a clear division of labor, and we don't have any problems." Qu Menghan nodded with satisfaction, "But will they agree?" ”

"Don't worry about this." Zheng Hanfei packed the tickets to them, "I already told him on the way back, and he agreed, I believe he will talk to Mo Gang properly, and then Officer Linghua will cooperate well with Mo Gang and Liszt, maybe you can find out who is the prisoner without us at that time." ”

Under the arrangement of Zheng Hanfei and Mengwu, the plan was formed, and then they discussed it in their room for several hours, and the perfection was insufficient, until the fiery red sun disappeared from the sky, and a crescent crescent crescent crescent climbed into the sky before stopping, after seeing them go back to the room, Zheng Hanfei and Mengwu lay on the bed one after another, thinking for several hours in a row, they were already a little unbearable, and now they just want to lie in bed and rest, and they have long left it behind for eating.

"What are you doing?" Meng Wu turned his head to look at Zheng Hanfei, but found that the other party was staring at the mobile phone screen, his fingers kept swimming on the mobile phone keyboard, and he couldn't help but ask curiously.

"Texting." Zheng Hanfei replied truthfully, "Send a text message to a person whose reasoning is not much different from mine, this time he didn't come, wait for the opportunity to introduce you to the acquaintance, I believe ......"

Before he finished speaking, a deafening explosion suddenly came from outside the room, and the firelight outside the window attracted the attention of the two, but Zheng Hanfei didn't notice that the signal grid of the mobile phone dropped directly from full to none......
