Qianyu's hand pushing the slider suddenly stopped. "Wait a minute..." With a dexterous hand, another set of components was added to the circuit. When Qianyu started sliding the slider again with the same rhythm,

At that moment, the sound of "tick-tick-tick" really appeared in everyone's ears.

Qianyu added a side tone component set so that Qianyu could tell whether he had made a mistake by listening to the sound. (The reason Qianyu didn’t add this component at the beginning was because it was the simplest one.

The success rate is the highest. Even adding a sidetone component group will reduce the success rate. Therefore, Qianyu must be blinded once to ensure that the message can be successfully sent once without too much distortion. After this time,

Only Qianyu will try to provide a complex alarm system with simultaneous increase in accuracy and alarm failure rate.)

"sos-sos-peop1e-at-1eisure1y-yu-house-on-mountain-bsp; "Then you can wait..." After finishing the telegram, Qianyu pinched the bridge of his nose and said tiredly, "Later

I would do it again..."

"By the way," Kenya asked curiously, "Since you can send signals like this, will others interfere with you unintentionally?"

"The chance is not high," Qianyu shook his head. "I chose not the most common 7.o23mhz frequency, but 7.o25mhz. This frequency band, this time, and our radio has a high signal power,

So it is almost impossible to be interfered. Especially in such a strong thunderstorm weather, it is difficult for ordinary radios to transmit too far. Our high-power radio is almost unique. Oh, by the way, can you help me switch the radio

Move to our house? I want to be able to hear incoming messages at any time."

"They are all asleep." After returning to the house, Qianyu looked at the three peaceful sleeping faces in the house and smiled slightly. However, after seeing Dr. A Li making a silent gesture, she remembered it again.

What. "Kenya-nii, don't move in yet. I need a component set with a jack that can plug in headphones, otherwise the sound from the speaker will wake them up."

...

"?" Qianyu was wearing headphones and reading a novel when he saw Conan walking in with a tired look on his face and quickly took off one of his headphones. "How's it going?"

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

"No matter what," Conan sat on the ground, even more tired. "It's over... everything is over, at least for the time being."

"But we still need to ask for help, don't we?" Qianyu pointed to the radio in front of him. "Besides, I still don't think Guangwei is the murderer."

"This is a very controversial issue, because he did not confess his murder method in the end, and always denied the crime of murder. Although from any point of view, he is the only possible killer... No, you can say

It makes sense, I need to go there."

"Where to go?" Qianyu was stunned.

"Go to the scene." Conan said and left the room again. Due to fatigue, his steps even staggered a little.

"..." Qianyu thought for a while and decided to go with Conan to have a look. "Doctor, they and this radio station are all left to you!"

Qian Yu could never imagine what he would experience.

Qianyu came to the crime scene and found that the door handle could not be turned open. "Well——"

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

Qianyu pressed the two buttons that Guangwei had pressed in sequence, but found that the door handle still could not be turned.

"What the hell?" Qianyu put his hands back in his trouser pockets and stood in front of the door, thinking.

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

"?" Qianyu quickly pulled the door open again, only to find that it had already been opened!

"Tch!" Qianyu's nerves immediately became tense - since whether the door is locked or not has nothing to do with those two buttons... maybe now, the real murderer who killed Guangzi is in this room, preparing to attack him

!

There were not many lights in the corridor and the brightness was very low, so Qianyu could only vaguely see that there was no suspicious person within his field of vision. Then the murderer must be hiding on the left and right sides of the door, and would attack him as soon as he entered. Then

...

Qianyu opened the Wuhen Umbrella halfway, and then held it on his head. Qianyu then took a deep breath and charged into the door - the strength of the Wuhen Umbrella ensured that he would never be attacked.

After Qianyu rushed into the house, he immediately knelt on his knees and slid forward. By adjusting the angle of his legs, he turned his body 18o degrees while sliding, so that he could calmly see the attacker behind the door. The traceless umbrella was also sliding.

She put it away, and Qianyu's hands were already buried in the umbrella. (Buried in the umbrella is not a meaningless action. When he was in the department store before, Qianyu originally wanted to use the same method to attack people coming up from the elevator, but he was

It’s just a list. It’s just that I’m not used to giving additional explanations in the text.)

There was no one behind the door, but it was his kneeling that destroyed the blood stains on the door, forming a vague mark of kneeling.

"What's going on? What was that sound just now?" Qianyu put down his umbrella and thought in confusion.

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

"Who's in there?"

"Sister Reiko? It's me, Qianyu brought by Dr. A Li on the third floor." Qianyu said, holding an umbrella and walking out. (The reason why Qianyu held the traceless umbrella and remained armed was that she really didn't dare to completely

Trust Reiko, because it's possible that he and the light guard did some trick. For example, he killed the photon with a low-effort lever rope or something. Although this is unlikely, it is indeed possible. The second point is that the murderer probably just passed

Some kind of cover-up or mechanism is controlling this place, and it's likely that it's around the two of them.)

"What happened?" Reiko asked. "Why are you in there?"

"Don't talk about this for now," Qianyu and Reiko kept some distance. "Sister Reiko, have you seen my partner, Conan wearing glasses?"
