A technical house in the world of detectives

Following.

As soon as He Yun arrived at the school, he heard Xiaolan complaining there.

“You don’t know the garden, Conan was sent back by a police car yesterday, this kid, and tricked me and my friends to go to the park to play.”

Xiaolan looked a little tired.

It is obviously a second-year high school student, but she has to do a lot of housewife work, which is also difficult for her.

“Good morning.”

He Yun came to his seat and greeted the two.

“Cousin, you’re here, it’s good that you called the police yesterday, you know? Those who followed Conan turned out to be the Italian bandit group…”

After Xiaolan saw He Yun appear, she immediately began to thank and told everything that happened.

Yuanzi also came over curiously and listened to the content of Xiaolan’s words.

Although there is no specific experience, what is certain is that Conan and these children don’t know where to get something that looks like a treasure map, and they didn’t expect it to be the code word for the robber group to hide gold coins.

Even if the gold coins were still not found, Conan and they almost died at the hands of the robbers.

“It’s Conan, they’re lucky, it just so happens that I recently cooperated with the police, so I saw them from the surveillance video.”

He Yun explained.

“That’s really lucky, otherwise…”

Yuanzi also felt a little afraid after listening to it.

Even a high school student like her is estimated to be unlucky when she encounters a robber, let alone a few children.

“Conan is still a child, it’s normal to be naughty, Xiaolan, you usually discipline him more.” He Yun said so, opened his school bag, and seemed to suddenly think of something: “I’ll make a few badges in a few days, the kind that can be positioned, to prevent children from running around.” ”

He Yun suddenly thought that he wanted to promote his own smart phone, maybe he could start with children.

Installing a mobile phone APP can locate the location of the child, I believe many parents will be willing to buy such a product.

“Can it be done to this extent?”

Yuan Zi was slightly stunned.

Is this technique actually used to prevent children from losing it? There are obviously more other uses.

“By the way, this is a gift for you.”

Two boxes were taken out from the bag, and on the pure white box, only an auspicious cloud mark was printed on it, representing their He Group.

There was no plastic film packaging on the outside of the box, and after Xiaolan and Yuanzi thanked each other, they opened the box directly.

Inside, it was the smart machine He Yun used before.

“Wow~~”

Xiaolan and Yuanzi happily held their mobile phones, full of joy.

“I was busy with some personal matters some time ago, so the time was postponed a little, but after a while, this phone will be on the market, you guys try it first, there is an instruction manual in it.”

He Yun briefly introduced how to use it, and the more complicated operation let Xiaolan and Yuanzi read the manual.

After spending a morning of recess, the two were a little familiar with the operation of mobile phones, but they were still a little unaccustomed.

But anyway, I liked it very much.

Because in this era, just transitioning from big brother and BB machines, even if there is a mobile phone, it is the same as the landline, which is full of buttons, and only a small screen displays the phone number and some other information.

The most important thing is that the people who can use mobile phones in this era can be said to be local tyrants, at least Xiaolan does not have them, and their family cannot afford to consume them.

Not to mention, He Yun sent her mobile phone, not only the function of making calls, but also installed a software called line, on which you can type and chat.

Just this one function surprised the two of them.

During the lunch break, the two were extremely unskilled in learning to type on their mobile phones, obviously face to face, but they had to use their mobile phones to chat, often a minute to type a few words, but they were very happy.

“Ahem…”

He Yun coughed twice, reminding them, but also lamented the power of smart phones, which actually directly widened the distance between people.

Hearing He Yun’s reminder, the two of them blushed, put down their mobile phones, and ate seriously, but the content of today’s noon chat was all related to mobile phones, and the two were too shocked by the functions of these mobile phones.

“At present, this software is only during the trial period, which means that it is only to test whether the software has bugs, and it cannot be used if it is too far away.”

He Yun said.

Now is not the era of mobile phone Internet access, the software installed in it is only a prototype, He Group is now communicating with operators, negotiating the use of base stations to use mobile phone networks.

If things come down and you want to go online, you can only use their mobile phones.

Coupled with He Yun’s self-made encryption technology, he is confident that he will not be simply cracked by anyone, let alone directly act on physical means, once someone tries to crack the program that will self-destruct.

If someone can copy his technology from a pile of discarded components, then that person must already have the ability to develop a system on his own.

“By the way, do you want to go to my family’s villa on the weekend?”

After lunch, Yuanzi suddenly proposed.
