Compared with mobile phones, the structure of this cryptographic electronic lock is much simpler. The core component is the chip, and important functions are completed by this chip.

Zhong Yue quickly figured out its principle, and now, he needs to add new functions based on its existing functions.

First of all, it must be able to connect to WIFI, so that the pictures taken by the camera on the gate can be transmitted online. In this way, it can view them through the mobile phone at any time.

Then, there needs to be an alarm system, and as long as someone tries to open the door, his mobile phone alarm will sound.

Finally, connect a high-voltage line. If it is found that it is a thief, it will be corona through remote control. The key is that it cannot be electrocuted.

"The door is foolproof, and there are windows?" He looked at the window. Although it was eighteen floors, it was probably impossible for some skilled flying thieves to suffer.

"Well, all windows must also be equipped with alarm systems."

Thinking of this, a light of inspiration flashed through his mind, "Just transform all the home appliances, create a home control system, and then fully automate everything."

He felt very excited when he thought about the scene. He was very enthusiastic and started to design it.

However, this work cannot be done in a short while. All electronic products are a system project. The more complex the system is, the more components it involves, the more troubles it is.

Just like a mobile phone, if you want to add a new function, it doesn’t mean you just add a component. You also need to consider power consumption, heat dissipation and other issues. It can be said that it will affect the whole body by one move.

These days, he has also tried to learn from mobile phones from various brands and wanted to "develop" a mobile phone with comprehensive functions, but the result is that he has produced many problems.

It was then that he realized that the development of electronic products was not as simple as he thought.

He knew that the biggest problem was still in himself, and his knowledge about electronics was too poor.

"It seems that if you have time, it's better to go to college to charge it."

When the newly prepared chip failed again, such a thought flashed through his mind.

……………………

Zhong Yue stayed in the house for half a month. In the past half month, he had only visited the store twice, and he sent his new phone to him, put down his things and left.

The most valuable thing in the store is mobile phones, which are all very clear. Besides, the store has a camera installed. He is very relieved to hand over the store to two people, not afraid of them making a fool.

Until one morning, after he finished exercising, he received a call from his mother as soon as he got home.

As soon as I connected it, I heard my mother’s complaint, “A Yue, why are you not at home early in the morning? Where did you go?”

He said with a lot of laughter, "Mom, why don't you call me before you come to see me? I've moved."

"Moving? Why move?"

"I'll tell you then that you are where I used to live, right? I'll pick you up."

"It's not me, it's your aunt's son Huang Qiuxun."

After listening to his mother's explanation, he realized that it was his aunt's son and his cousin. Because he was admitted to the university here in the college entrance examination, he wanted to come here to get familiar with the environment during the summer vacation. He specifically asked his address and wanted to stay with him for a few days.

Last night, the kid took someone else's ride-hailing ride. Because he was driving a night bus, the owner kindly sent him downstairs where Zhong Yue used to live.

Unexpectedly, after knocking on the door for a long time, no one responded. The phone ran out of battery again, so I had to call home on a public phone, then find Zhong Yue's mother and call Zhong Yue's phone.

After figuring out the whole thing, Zhong Yue quickly changed his clothes and went out. It was less than seven o'clock now, and his cousin was unfamiliar with the place and could not contact him. So nothing could happen.

After going downstairs, he headed straight to the subway station. It was difficult to take a taxi at this point, so it was better to take the subway to fast.

At this time, there are many people taking the subway, most of them are students wearing school uniforms.

Zhong Yue grabbed the support rod, put on the Bluetooth headset, called his aunt's house first, and asked about his cousin's mobile phone number. Just as he was about to call, he found a familiar figure opposite him.

"Is it her?"

It was half a month ago that the female student smashed a milk box at the garbage point. Today she tied a small braid on her left, but she didn't recognize her just now. She and a female classmate were facing this side.

"Do you want to say hello?"

He thought to himself that when he finished exercising every morning, it was almost the time for her to go to school, and he often met her downstairs, and she was also an acquaintance.

But thinking about her usual aloof look, he still gave up this idea so as not to make things boring.

Just as I was thinking, I saw her say a few words to her classmates and walked towards her.

"Can you lend me your headphones?" the girl asked quietly as she looked at the headphones he wore on her ears.

Zhong Yue took off his headphones and handed them to her, "Are you talking about this?"

The girl seemed to breathe a sigh of relief, carefully pinched her headphones, pursed her lips, and said, "When will you get off work?"

"Um?"

"I'll finish school at 4:00 in the afternoon and wait for you at the subway station just now at 4:30."

Knowing that she had misunderstood, Zhong Yue didn't explain and nodded with a smile.

The girl returned to her classmate and connected her headphones to her cell phone.

"Xiuxiu, who is that man?" the classmate asked.

The girl named Xiuxiu replied casually, "A uncle living downstairs." While auditioning, "I won't miss Wangwang's new song now."

The classmate said with some concern, "Didn't you say that the release is at 9 o'clock? Class was in at that time, and what should I do if the teacher found out?"

"Okay, I put my hair down, the teacher will definitely not be able to find it."

……………………

It was already eight o'clock when Zhong Yue received his cousin.

His cousin Huang Qiuxun was squatting at the entrance of the corridor, holding a bun in one hand and a bottle of mineral water in the other, eating it deliciously. Seeing him coming, he jumped up and shouted, "Brother, you are finally here."

Zhong Yue looked at him and couldn't help laughing, "Stop eating this, go, I'll take you to have something delicious." As he said that, he helped him pick up his suitcase.

Huang Qiuxun threw the buns in his hand into the trash can and followed.

Young people like foreign fast food, so Zhong Yue took his cousin to the nearest KFC and ordered some breakfast.

"Why is your phone running out of power?" Zhong Yue had nothing to say.

Huang Qiuxun is six years apart from him, and the generation gap is still very deep. In addition, the two families are not close to each other and there are not many intersections. They have basically never played much together. Especially after he went to college, he only saw him a few times when he came home during the Chinese New Year. That sense of strangeness will be difficult to eliminate for a while.

Huang Qiuxun's face suddenly collapsed and she said in pain, "It's not that there is no electricity, it's broken. I just bought it last month."

Zhong Yue's heart moved and said, "It just so happened that I was learning to repair my phone. Take it out and I'll take it out and take it a look."

When Huang Qiuxun heard this, she wiped her hand on her body, took out a cell phone with a broken screen from her pocket, and looked at him hopefully, "Brother, can you repair it?"

Zhong Yue looked at it a few times and found that the phone was the latest one from Huawei. Except for the cracked screen, the rest of the room was intact. He nodded affirmatively, "Just change the screen, it's very simple. I'll repair it for you when I go back."

"Thank you brother." Huang Qiuxun was overjoyed and thanked him repeatedly.
