Conan: I am the murderer

"For example, what if you have a fever?"

Xiaojing touched her little face, to say her current body temperature, it must be a high fever

"If you're sick, then of course the next step is"

The corner of Koizumi's mouth: tilted up, "received treatment"

Feilu reminds you: reading three things

Chapter 270: Do you want to grow up

"What's the age, still playing treasure hunts"

Ke Lan looked at the dilapidated map in his hand, speechless in his heart

Early this morning, Yukiko went out and threw Ke Lan to Dr. A Li's house and asked him to take care of him

What, she's not a child who doesn't understand anything, can't she be allowed to read a new detective novel at home during a rare vacation! Then Dr. A Li used treasure hunting as a gimmick and took her and a few other children with her. Come together in a deep mountain

"Doctor, what is the treasure recorded on this map?"

Ayumi asked suspiciously

"Hehe, you'll know when you find it."

Dr. A Li pretended to be mysterious and sold a secret

"Is it gold, or is it diamonds?"

Mitsuhiko began to make bold guesses

"Treasures, they must be very valuable things,"

Yuanta said happily: "It can definitely be exchanged for a lot of eel rice!"

Hehe, hope it's not a bad joke left by the doctor

Ke Lan looked at the names of the markers on the map, and his heart was not fluctuating. He even wanted to laugh a little.

"Could it be the testimony of friendship?"

Suddenly, a somewhat calm voice sounded

"This, this is not impossible"

Suddenly the answer was revealed, Dr. A Li was a little embarrassed: 囧 looked at the little girl standing beside Ayumi

Looks like she's pretty smart

Ke Lan couldn't help but take a look at his deskmate at school——Haihara Ai

"By the way, for the convenience of contact, this is a detective badge, as long as it is opened like this, you can have a wireless conversation"

Dr. Ali quickly changed the subject, took out a brand new detective badge, and introduced Xiaoai how to use it

"Ultra Small Radio"

Xiao Ai weighed the detective badge in her hand and asked Dr. Li: "How long can the call last at most?"

Dr. A Li: "Uninterrupted, two hours"

Xiao Ai: "The power supply method is"

Dr. Li: "Button battery, one 1, I usually help to replace it"

"That's it"

Xiao Ai fiddled with the detective badge, and said, "For a badge of this size, you can consider adding solar auxiliary power supply to reduce or even avoid disassembly and installation of batteries, and it can also be better waterproofed."

Dr. Li: ""

It makes sense, why didn't he think of it before? On the detective badge, there are nearly 50% of the material in the area, which can be replaced by solar panels

This improves both applicability and durability. It's the best of both worlds! "Haihara-san, isn't the sun in the sky? Even a doctor can't get it down."

Yuan Tai couldn't understand what Xiao Ai was saying, Shi Guangyan rolled his eyes silently, "Yuan Tai, what Hui Yuan is talking about is solar energy, a technology that converts the heat in sunlight into dots!"

Mitsuhiko's knowledge reserve is much more than Yuan, and he began to popularize it.

"Wow, Haiyuan-san looks so professional!"

Ayumi looks at Xiao Ai with a hint of admiration in her eyes

Even Ke Lan couldn't help but praise Xiao Ai from the bottom of his heart. The detective badge invented by the doctor was either used and ran out of electricity, or it was easy to fall on the ground and break. The badge of a single unit was too much, and it was already damaged by liquids such as milk drinks. broken several times

"Cough cough, everyone, it's getting late, let's hurry up and start treasure hunting!"

"I'm fishing here slowly, and I'll prepare dinner for you to eat when you come back. I wish you a happy adventure!"

Dr. A Li hurriedly diverted everyone's attention. He had already seen a mocking smile in Ke Lan's eyes, as if he was saying, "Why are you worse than a little girl?"

"Youth detective team, set off on a treasure hunt!!!"

Ayumi, Mitsuhiko, and Yuanta, the three little boys happily lead the charge

As for Xiao Ai, she followed behind Ke Lan.
