Chiba's hand pushing the slider suddenly stopped. "Wait a minute... With a skilful hand, another set of components is added to the circuit. When Qian Yu began to slide the slider in the same rhythm again, the sound of "Didi Da" really appeared in everyone's ears.

Chiba added a sidetone element group, so that Chiba could tell if he had made a mistake by listening to the sound. (The reason why Qianyu didn't add this element at the beginning is because the simplest transmitter has the highest success rate, and even just adding a sidetone element group will reduce the success rate, so Qianyu must send it blindly once to ensure that the message with not too much distortion can be successfully sent out once.) After sending this time, Chiba will try to send a complex transmitter system with a simultaneous increase in accuracy and transmitter failure rate. ）

"Then you can wait... After sending this telegram, Qian Yu pinched the bridge of his nose and said tiredly, "I'll send it again later... ”

"Anyway," Kenya said curiously. "Since you can send a signal like this, will others interfere with you unintentionally?"

"It's not very likely," Qian Yu shook her head. "INSTEAD OF THE MOST COMMON FREQUENCY OF 7.023MHZ, I CHOSE 7.025MHZ, WHICH IS THE FREQUENCY BAND, THIS TIME, PLUS OUR TRANSMITTER HAS A HIGH TRANSMISSION POWER, SO IT IS ALMOST IMPOSSIBLE TO BE INTERFERED WITH. Especially in such a strong thunderstorm, it is difficult for the general radio to travel too far, and our high-power transmitter is almost a standout. Oh, by the way, can you help me move the radio station to our house? I want to be able to hear the messages I receive at any time. ”

"They're all asleep," Chiba smiled as she looked at the three sleeping faces in the room, but remembered something after seeing Dr. Asasa make a silent gesture. "Brother Kenya, don't move in yet, I need a component set with a jack for headphones, otherwise the sound from the speaker will wake them up."

。。。

“？” Qian Yu was wearing headphones, reading a novel, but saw Conan, who looked tired, walking in and quickly taking off one of the headphones. "How's it going?"

"Guangwei is under house arrest in his own room, but I always feel like it's not over yet." Conan's expression looked distressed. "I always feel uneasy...

"Anyway," Conan said, sitting on the ground, even more tired. "It's over ... It's all over, at least temporarily. ”

"But we still need to call for help, don't we?" Qian Yu pointed to the transmitter in front of him. "Besides, I still don't think Guangwei is a murderer."

This is a very controversial issue, because he did not confess his murder methods in the end, and he always denied the murder. Although from any point of view, he is the only possible killer ... No, you have a point, I need to go there. ”

"Where to go?" Qianyu was stunned.

"Go to the scene." Conan said, leaving the room again. He even stumbled a little from exhaustion.

“。。。” Qian Yu thought about it, but decided to go with Conan to have a look. "Doctor, they're going to ask you for this station!"

Qian Yu would never have imagined what he would go through.

Qian Yu came to the scene of the crime and found that the doorknob could not be unscrewed. "Hmm-"

Guangwei also mentioned this situation at the time, and the determining variable of whether the door can be opened or not is ...

Qian Yu pressed the two buttons that Guangwei had pressed in turn, but found that the doorknob still couldn't be unscrewed.

"What the hell?" Qian Yu put her hand back in her trouser pocket and stood in front of the door thinking.

"Bang!" A muffled noise came from inside the house.

“？” Qian Yu hurriedly pulled the door again, only to find that the door had been opened!

"Cut!" Qianyu's nerves immediately tensed - since whether the door is locked or not has nothing to do with those two buttons... Maybe right now, the real murderer who killed Photon is in this room, ready to attack himself!

There weren't many lights in the hallway, and the brightness was low, so Qian Yu could only see that there were no suspicious people in his field of vision. Then the murderer must be hiding on the left and right sides of the door, and will attack him as long as he enters. So...

The Traceless Umbrella was opened halfway by Chiha, and then pressed against his head by Chiba. Qian Yu then took a deep breath and charged inside the door - the strength of the Traceless Umbrella could guarantee that he would never be attacked.

As soon as Chiba rushed into the house, he slid forward on his knees, adjusting the angle of his legs to twist his body 180 degrees in the slide, so that he could calmly see the assailant behind the door. The Traceless Umbrella was also retracted during the glide, and Chiba's hands were already buried in the umbrella. (Burying in an umbrella is not a meaningless action, when I was in the department store before, Chiba originally wanted to attack the person coming up from the elevator in the same way, but it was just put in a position.) It's just that I'm not used to making some additions in the text)

There was no one behind the door, but it was his own slippery kneeling that destroyed the bloodstains on the door, forming a vague slippery kneeling mark.

"What's going on? What was that sound just now? Qian Yu put down her umbrella and thought in disbelief.

"Yes ... Who is it? "From outside the door came the voice of Reiko (the girl who saw Koe trying to open the door in the previous chapter, and her room was not far from the scene of the murder)." Who's in it? ”

"Sister Reiko? It's me, the thousand feathers brought by Dr. Asasa on the third floor. Qian Yu said, and walked out with an umbrella. (The reason why Chiba is holding the Traceless Umbrella and staying armed is that he really doesn't dare to fully trust Reiko, because it is possible that he and the light guard have done some tricks.) For example, use a labor-saving lever + rope sleeve or something to decapitate the photon. While this is unlikely, it is possible. The second point is that the murderer is likely to be just controlling this place through some kind of trick or mechanism, and it is likely that he is next to the two of them. ）

"Is something wrong?" Reiko asked. "Why are you in there?"

"Don't talk about that yet," Chiba and Reiko kept some distance. "Sister Reiko, did you see my partner, Conan with glasses?"

Conan came down earlier than he did, and he was already here, so there's no reason why he hasn't arrived yet?
