"Let's go back!" Zheng Hanfei beckoned to the two of them, since there was another murder case, then he was in no mood to crack the code, so it was better to return to the villa first and investigate whether Lu Yun appeared in the monitoring place.

Xi Chen and Geng Mu nodded one after another, glanced at the charred corpse, and there was a trace of sadness in their eyes, in their opinion, Lu Yun's death was purely an accident, and it was not as careful as Zheng Hanfei thought.

……

"What the hell is going on? Where did you go, it scared the hell out of me. After the three of them returned to the villa, the sky gradually darkened, and then they heard Mu Tian shouting, and when they heard the sound, they saw Mu Tian hurriedly running out of the gate, looking anxious, no wonder, all the other people in the villa disappeared, coupled with the occurrence of the murder, it is easy to think that they have died at the hands of the murderer.

"Lu Yun is dead!" Zheng Hanfei said lightly, judging from the way he was thinking, it was very imaginary that he was telling others, but it was like talking to himself.

"What?! Lu Yun is dead! So we don't have to worry about being killed? Mu Tian's face showed a hint of excitement, believing that the excitement on everyone's face would naturally show when they heard that their lives were no longer threatened.

"It's better to be careful." Zheng Hanfei glanced at him, for some reason, he always felt that Lu Yun's death was becoming more and more abnormal, but he couldn't say that it was abnormal.

At this time, Zheng Hanfei is like choosing the right path from the two paths, if he is not careful, he is likely to fall into endless darkness again, so he must be cautious and cautious, once he makes a mistake, then the tragedy is likely to happen again.

"By the way, Mr. Mutian, can you show me the tape again." Anyway, Zheng Hanfei decided that this time he must quickly solve the case and find out the real culprit, so he said seriously.

"Huh?" Mu Tian didn't seem to understand Zheng Hanfei's words, and stood there stunned.

"Mr. Mutian! Videotape! Zheng Hanfei shouted, his eyes couldn't help but have some doubts, and his intuition told him that Mu Tian seemed to be a little wrong.

"Oh! Got it! Mu Tian nodded, "Mr. Zheng Hanfei, you see that it is getting late, and your injuries are not healing, I see that I will personally send the video tape to your room, and you can watch it in the room." ”

"Isn't that funny? You're so busy, I'm a little upset. ”

"Not busy, not busy!" Mu Tian smiled, quickly shook his hand, and then walked into the villa.

"Detective Zheng Hanfei, you have a good rest!" Xi Chen said, "I'll ask Geng Mu to deliver dinner to your room in a moment." ”

"Thank you, Mr. Xi Chen, for your hard work, Aunt Gengmu."

"It's not hard!" Maybe it was Zheng Hanfei's aunt and aunt's call, Geng Mu smiled happily, shook his hand with Mu Tian, and followed Xi Chen into the villa.

I'd better go back to my room. Zheng Hanfei sighed, the reason given by Mu Tian was indeed very good, although he really wanted to go to the monitoring room to get the tape in person, but he felt a faint pain in the wound on his back, in order to prevent the wound from cracking or the degree of wound dehiscence aggravated, he could only go back to check how it was first, and then deal with it accordingly.

Thankfully, the wound didn't open! After returning to the room, Zheng Hanfei checked his back in the mirror, and found that the wound showed no signs of cracking, so he couldn't help but breathe a sigh of relief, put on his clothes, and after about ten minutes, he heard a knock on the door and shouted to please come in.

"No, you want a tape!" Mu Tian opened the door and reached out to hand Zheng Hanfei two boxes of videotapes, "This is the record behind, I hope you find something." ”

"Thank you!" Zheng Hanfei took the tape and thanked him.

"By the way, your injuries aren't a big problem." Mu Tian asked with concern.

"It's no big deal, thank you for your concern." Zheng Hanfei moved for a moment and said that he had no problem.

"Alright, I'm leaving!" After speaking, Mu Tian closed the door, leaving Zheng Hanfei alone in the room.

What's going on? Zheng Hanfei was full of questions, what is this feeling of disharmony? Mu Tian's appearance always felt weird, why did it take so long for him to send the tape over?

Alas! Zheng Hanfei scratched his head in annoyance, inserted the videotape into the tape recorder in the room, and spent nearly three hours watching two boxes of videotapes, which was the result of him fast-forwarding, otherwise, Zheng Hanfei didn't know when he would be able to finish it.

There's no clue at all! Zheng Hanfei frowned, although he used fast forward, he believed that his eyes did not miss any details, but he just didn't see the housekeeper appear in the surveillance, as if the housekeeper was deliberately hiding.

But how did he get to that place? Zheng Hanfei pinched his chin, no matter what, when he got there, he would definitely have to pass through the monitoring range of the camera, and there was no place to hide.

Absolutely! With so many cameras in sight, there must be an invisible but real hidden road, but where would it be?

"Ah~" Zheng Hanfei yawned, looked at the moonlight outside the window, he understood that it was very late now, and there were no clues to look for in the videotapes, he decided to return the two boxes of videotapes to Mu Tian first, and then go to sleep and greet the next day energetically.

"Huh? Mr. Mutian? Zheng Hanfei walked out of the room, and when he walked to the staircase, he saw Mu Tian passing by the stairs, and couldn't help but say something.

"Huh? Mr. Zheng Hanfei, why haven't you rested? Mu Tian was also a little surprised that Zheng Hanfei appeared here.

"I'm going to give you the tape back!" Zheng Hanfei shook the videotape in his hand, "It's you, why did you come out?" Aren't you supposed to be in the surveillance room all the time? ”

"Ah, that's the old man who asked me to come out, he said that Lu Yun is dead, so you don't need to let me stay there every day, just hand it over to the anti-theft system and change it to an automatic camera."

"That's it!" Zheng Hanfei walked down the stairs, patted Mu Tian on the shoulder, and said, "In this case, I will accompany you to the monitoring room, although the threat has been resolved, it is better for us to be careful." ”

"That's right!" Mu Tian nodded, and took Zheng Hanfei to the monitoring room, and after ten minutes, Zheng Hanfei saw this heavy door again.

"Huh? What about the keys? Mu Tian dug into his pocket and said a little anxiously.

"What's wrong?"

"The key is missing!" Mu Tian emptied his pocket and said, "I remember putting the key in my pocket." ”

"Then you'd better go to your room and have a look." Zheng Hanfei shook his head helplessly and proposed, "It's very likely that you put the key there." ”

"That's right!" Mu Tian nodded, and hurriedly ran back to the room, Zheng Hanfei immediately followed, before leaving, he glanced at the heavy door, and a trace of doubt appeared in his eyes.

……

"How so?" Mu Tian hurriedly rummaged through the drawers and shouted, "There is no key anywhere." ”

"Really?" Zheng Hanfei sighed, "In this case, what about the management there?" What about these two cassettes. ”

"Let's put it here for now." Mu Tian said with some disappointment, "As for management, I'm not worried, the cameras are all in automatic mode and will work normally, it seems that when the ship comes, I will ask the master to change the door." ”

"Do you mean...... This door only has this one key? ”

"Yes!" Mu Tian nodded, "This is all requested by the master, I lost the key twice before, and the master directly ordered the door to be replaced, which consumed a lot of time, but I didn't expect to trouble the master again this time, alas, I really don't want to trouble the master." ”

"It can't be helped!" Zheng Hanfei shrugged his shoulders, he could only feel deep sympathy for this matter, he couldn't help at all, said a good rest, and turned to leave Mu Tian's room.

That's right! It's time to take a look at Xi Xun's room to prove your reasoning right! When Zheng Hanfei was about to walk to the door of his room, he suddenly thought of this important matter, so he turned around and walked into Xi Xun's room, at this time, he found that the lights in the room had not been changed at all, and the room was still dark, and he could only rely on the moonlight outside the window and the light in the corridor to vaguely see the outline of the room.

By the way, Mu Tian's flashlight is still on my hand! Zheng Hanfei patted his head, took out a flashlight from his pocket, turned on the light, and looked at Xi Xun's corpse that still hadn't moved, after such a long time, the corpse faintly smelled, if it wasn't for Zheng Hanfei not closing the window before, maybe this room would be full of corpse smell.

Sure enough, yes! Looking at the small mark on the left pedal of the upright piano, Zheng Hanfei smiled slightly, and just as he was about to leave the room, a trace attracted his attention.

This is! Zheng Hanfei squatted down, put on gloves, and clicked on the ground, then looked at the shining fragment in his hand, his pupils shrank slightly, and he realized that he had made a mistake, a preconceived mistake, and the truth did not seem to be what he imagined......
