"Murder!?Is it really murder?" Li Xiaoxian twisted his eyebrows, his face incredulous, "How could it be? Who is the suspect?"

"Also, what do you mean by playing with the leftovers, how many brushes do you have, I don't know yet?"

"Hmm...... This ......" Zhou Tang realized that he had spoken out, and quickly pointed to the deceased's room and changed the subject, "I said before, the deceased's room is too clean!"

"The room is so clean, you mean......" Li Xiaoxian asked with a wink of big eyes, "This is not the first scene?"

"But...... This can't be, right?" she said, pointing to the elevator outside, "The elevator surveillance can clearly see that the deceased came out of the elevator from the 10th floor.

"If he leaves the 10th floor, he will also be filmed by the surveillance!

Also, the place where he fell was also right under the balcony of his house, how could it not be the first scene?

"If this isn't the first scene, where would it be?"

"Xiaoxian, don't get excited, hehe......" Zhou Tang comforted calmly, and then asked another irrelevant question very seriously, "Did you bring an umbrella?"

"What!?" Li Xiaoxian couldn't react, scratched his head and replied, "On this hot day, why do you bring an umbrella?" Oh...... You mean parasols, right?

"This girl is born white and does not tan, and never brings an umbrella ......"

"Okay!" Zhou Tang turned around and opened the shoe cabinet of the deceased's house and rummaged through it.

"Big brother, hey......" Li Xiaoxian exclaimed, "This is the scene of the crime, you can't touch the deceased's things casually!"

However, Zhou Tang ignored it, quickly found an umbrella, and then said to Li Xiaoxian:

"Come, come with me!

"Let me tell you, where is the first scene?"

With that, he snapped his fingers and walked out of the room first, heading straight for the elevator.

There are two households here, and there is only one elevator in the corridor.

After pressing the elevator button, Zhou Tang opened the umbrella, and then pulled Li Xiaoxian under the umbrella.

With a ding dong, the elevator door opened in front of the two of them, and Zhou Tang held up his umbrella and pulled Li Xiaoxian into the elevator.

"You...... What is this for?" Li Xiaoxian still didn't quite understand, "Playing an umbrella in the elevator, are you worried that it will rain here?"

"Hehe......" Zhou Tang smiled slightly, "Can't you see it? I'm trying to block the camera!"

After saying that, as if by magic, a delicate cone appeared in his hand! This cone was also found from the shoe cabinet......

Immediately afterwards, Zhou Tang squatted in the elevator, neatly unscrewed the screws on the elevator controller, and then opened the control box.

"Monitoring, won't you?" Li Xiaoxian was still in the fog, muttering, "We are the police, why do we have to avoid monitoring? Are you afraid of being seen by the security guards?"

"Look! Sure enough, it's all the leftovers I played with back then," at this time, Zhou Tang pointed to the circuit board in the elevator control box and said, "There is an extra set of controllers in here......

"Well, here......" he said, pointing to a black device, "it's the extra piece with a remote control device and a converter on it......

"With these things, someone can remotely switch between two sets of control panels, so as to control the floor display button of the elevator, and he can make the button display any floor......"

"Oh...... Ah!?" In an instant, Li Xiaoxian finally understood what Zhou Tang meant, and immediately exclaimed, "You...... You, you, you...... You're saying that someone took advantage of the elevator's floor display button, which ...... That's too slippery, isn't it?"

"Yes," Zhou Tang said, "What makes people angry is that this thing was invented by me first, but unfortunately I couldn't apply for a patent and was infringed by someone, sad ......"

"Tang ...... Brother Tang ......" Li Xiaoxian swallowed his saliva and said in surprise, "Don't be joking yet!"

"Since the murderer did something on the floor display button, then last night, the deceased ...... Is it possible that the deceased did not go to the 10th floor?

"That'...... Which floor did he go to?"

"Xiaoxian," Zhou Tang asked calmly, "You carefully recall the video of the deceased taking the elevator, do you feel that the elevator floor button in the video is faster than normal, or is it slow?"

"Hmm...... Hmm......" Li Xiaoxian recalled with his heart, and thought for a long time before he said, "I feel that it seems to be a little faster than normal, right?"

"But...... I'm not sure, or ...... I'll ask Kong Wang to watch the video replay again......"

"No need!" Zhou Tang said, "Didn't you just say that there is a drying rack on the 11th floor?"

"Oh...... Oh...... Oh my God!" Suddenly, Li Xiaoxian suddenly realized and said in surprise, "So, the murderer is the deceased's downstairs!?"

"The Dead...... Actually fell from the 9th floor?

"Really...... Is it really murder!?"

"Look," Zhou Tang was still calmly analyzing, "The murderer made a move on the elevator and could remotely control these two sets of circuit boards.

"Usually, he keeps the elevator running, so no one notices.

"But last night, when the deceased entered the elevator, he suddenly changed the floor button display, making the deceased mistakenly think that he had gone to the 10th floor, when in fact, the deceased was leaving the elevator from the 9th floor.

"Not to mention that the deceased drank alcohol, even if he didn't drink, it is difficult for him to distinguish ......"

"Next," Li Xiaoxian analyzed, "The deceased opened the door and thought it was his own home, but he didn't expect that it was actually the murderer's house!?"

"Then," Zhou Tang said, "the murderer attacked him, or took control of him, and finally pushed him off the balcony!"

"In this way, it can be explained why the deceased's home was so clean, because he never returned to his home at all!"

"Oh my God!" Li Xiaoxian said in shock, thinking in horror, "So...... The person who lives on the 9th floor is the murderer?

"I ...... I'll check right away, who lives there?" As she spoke, Li Xiaoxian took out her mobile phone and wanted to contact the other team members, but with the mobile phone in her hand, she thought of a terrible thing again, and hurriedly asked Zhou Tang, "Wait a minute, you are holding an umbrella and avoiding the elevator monitoring, it is difficult to ...... Isn't it to avoid security, but ......"

"Yes," Zhou Tang said with a smile, "There are so many residents in the building, although it is eleven o'clock in the evening, but the murderer cannot ensure that the deceased is riding alone in the elevator!"

"Otherwise, once the deceased rides with someone else, the murderer's plan will be revealed!" So," Zhou Tang said, pointing to the top of the umbrella, "I guess the murderer must have installed monitoring equipment in the elevator and can see the situation in the elevator." ”

"No......" Li Xiaoxian hit a spirit, feeling a chill rise up his spine, "You are worried that the murderer will see us, so you hit the umbrella ......"

"Of course," Zhou Tang smiled, "What if he sees that I opened the elevator control box, then he immediately ran away?"

"The murderer ......," Li Xiaoxian said nervously, "Is the murderer really still at home?"

"More than 80 percent!" Zhou Tang said confidently, "If I were the murderer, I would definitely not want to appear on the surveillance screen in the close proximity to the crime."

"I would choose to wait at home, wait for the right time, and then remove the control panel in the elevator, so that I can sit back and relax......"

"This ......" Li Xiaoxian swallowed hard, already comprehending Zhou Tang's meaning, and immediately said excitedly, "Are you telling me that now is the best time to arrest him?"

"That's right," Zhou Tang smiled evilly, "While the monitoring and remote control equipment are there, if you don't catch it now, what are you waiting for?"

At this time, the elevator descended to the first floor, and the door had been opened, and several residents were standing outside the door who were about to enter the elevator.

"I'm sorry, I'm sorry......" Li Xiaoxian quickly closed the elevator door, shut the residents out, and then turned on the walkie-talkie and shouted, "Everyone bring their equipment and come to the 9th floor to gather immediately!!"
