Dr. A Li's house.
Conan threw his schoolbag aside and lay down on the sofa. He thought about what he had said to Xiaolan before. The more he thought about it, the more he wanted to pick at the wall because there was a big light bulb at the scene...
Ahhhhh, it’s ruined, the doctor will definitely tease me about this in the future!
"Shinichi, is the fax machine I made easy to use?" Dr. Ali asked with a smile.
As soon as the doctor asked this, Conan immediately sat up full of resentment and complained: "It's this prop you invented, doctor, that almost caused me to be exposed today..."
"Hey, Shinichi, you have to be more conscientious when you speak. Is this prop I invented really so useless?" Dr. Ali asked angrily, inserting his hands into his waist.
"Well, it's not completely useless. It's still somewhat useful." Conan shook his head and said honestly, "However, this is just a fax machine put into a lunch box, and it doesn't have much technical content."
Dr. A Li curled his lips, "It's not because you called yesterday and asked me to make props that can't be discovered by Kong, so I didn't add more technological elements to the fax machine."
"Oh, so doctor, you have already made a tool to deal with Kong?" Conan looked happy and asked quickly.
Dr. A Li showed a row of neat teeth and said with a proud smile: "Of course, who am I? Dr. A Li, the first inventor of rice cakes!"
In order to see the new props quickly, Conan complimented him repeatedly: "You are so humble. You are so humble. He should be the first inventor of the Chicken Country."
"Hahahaha~" Dr. Ali was very impressed by what he heard. He turned around and walked into a room, then walked out with two things.
"Belt? Mask?" Conan looked at the props in the doctor's hands with confusion on his face, unable to guess their functions.
"Shinichi, you might as well guess their functions. How about you, a famous detective, can you guess it?" Dr. A Li raised an eyebrow at him provocatively.
"Are you testing me?" Conan straightened his glasses frame, and the lenses reflected a bright light at a certain angle. Then he began to reason, "First of all, this belt, judging from the length, is obviously for adults. Yes, since it is for adults, and it is also helpful to me, it is most likely for uncles. The specific function is... amplification?"
"As for the mask, if I guess correctly, it's a voice changer."
Dr. A Li was amazed and nodded: "Shinichi, as expected of you, you guessed everything right!"
As he spoke, he raised the belt with his left hand and explained: "This is a belt-type loudspeaker that can be used with a voice changer to turn Xiaolan and her father into a ventriloquism master in an instant."
Then, he raised the mask again and said, "This is a mask-type voice changer. Its general function is the same as your butterfly-type voice changer, but it is more concealed and has an active silencing function. When this function is turned on, even if you speak loudly, Even the person on the other side cannot hear his speech. Only when a loudspeaker is connected can the sound be emitted from the loudspeaker."
Conan nodded repeatedly. When the doctor finished explaining, he couldn't help but praise: "Wonderful, doctor, you are such a genius! Let me try it!"
Dr. Ari proudly handed over the mask-type voice changer, and then because the waist was too thick, he could only tie the belt on his thigh and said: "Shinichi, there is a button on the right strap of the mask, press it You can match it with the belt and activate the loudspeaker on the belt. When the right strap vibrates, it means the matching is successful and you can speak."
Conan manipulated the mask-type voice changer and found that its operating logic was the same as that of the butterfly-type voice changer and could adjust different voices. So, he adjusted Dr. Agasa's voice, put it on, and reached out to fumble with the straps. , touch a small raised button and press it.
Suddenly, the straps vibrated together.
"Although my body has become smaller, my mind is still bright." Conan tried to speak, and then Dr. Agasa's voice came from the belt-type loudspeaker.
Of course, there is still sound coming out of the mask.
"Press the button on the left strap and the entire mask will vibrate, which means the silent mode is turned on. Press it again and it will vibrate again, which means the mute is released." Dr. A Li said.
Conan immediately started experimenting and quickly became familiar with all the operations. The overall experience is that it is much better than the previous Guoben, but there are also problems.
"Doctor, this mask-type voice changer is fine if you wear it when you are sick or having a cold, but it would be too conspicuous if you wear it during normal times, especially in summer."
Dr. A Li nodded, "I also know this. I actually want to make a collar-type voice changer, but time is limited, so I can only make a mask-type voice changer in case of emergency. Give me some time, and I will make one for you. A collar-type voice changer with the same skin color, or simply a high-neck voice changer, which will make it much easier for you to reason and handle cases."
Conan thanked him from the bottom of his heart: "Doctor, thank you. If it weren't for you, I really don't know what I would have done."
Dr. Ali shook his head and said: "I can only provide you with these small help. If you want to defeat that mysterious organization, you still have to rely on yourself."
"Yes, I know. Now that my uncle has become famous, I think I will be able to get in touch with them over time." Conan said solemnly.
When the mysterious criminal organization was mentioned, both Conan and Dr. Ali stopped smiling and their expressions became serious.
The scene fell into silence for a moment. The organization was really too mysterious and no valid information had been obtained so far.
At this time, Dr. Ari seemed to have remembered something, and took out something as big as a palm, like a manual, from his pocket, and said, "By the way, Shinichi, this is a wireless power bank that can charge a belt-type loudspeaker. Theoretically, the loudspeaker on this belt can be used for a year if used once a week, but you still have to wear it. As long as it is attached to the head of the belt, you can charge the loudspeaker, even if it is separated by A layer of clothes is fine. Look at the two lights dimly on the belt strap. If both lights are off, it means there is no power."
"I will make a few more belts, and then you can take them back so that Xiaolan's dad can use them interchangeably. Oh, and there are also these button-type loudspeakers, just in case Xiaolan's dad doesn't wear a belt one day. It can be used in emergencies.”
Conan reached out and took the power bank. It felt like it was falling into his hand, and it was quite heavy. Button-type loudspeakers don’t weigh much and are very light.
He looked at the props he had and felt like "I'm going to fight ten". He said confidently: "With these props, I will get twice the result with half the effort. It's only a matter of time before I find that organization."
"Well, as long as Xiaolan's father's reputation increases and his contact area becomes larger, he will definitely find them." Dr. A Li nodded.
"It's getting late, doctor, I should go back." Conan took out the fax machine from his schoolbag and put all the props in it.
"No rush, let's go back after dinner." Dr. A Li took off the belt on his thigh and put it into Conan's schoolbag.
