After Zhou Cheng and Cheng Yuan took the admission notice from the Admissions Office of UCAS, they had just returned to their place of residence when He Hua called.

"Yuanzi, do you have a place to stay? Mom wants to go and visit you and Chengzi, and also stay in the capital for a few days."

Cheng Yuan: "..." He thought of the exercise every night, and his cheeks were a little hot, "Yes, there are, but Chengzi and I set up a desk in that room for study."

"Oh? Really? Which neighborhood are you in? See if there are any well-decorated houses? The ones that you can move in with your bags. Mom can go directly to buy one next to you, so I won't mess with you two."

Seeing that He Hua had already decided to come, Cheng Yuan struggled powerlessly, so he winked at Zhou Cheng for advice, and Zhou Cheng asked in a low voice, "Aunt He doesn't collect rent anymore? Such a big three-building complex, it would take a lot of effort to take care of it. "

Cheng Yuan understood, and immediately threw the question to his mother, "Mom, don't you collect rent anymore? You have to collect rent every month, so don't worry about it. Chengzi and I are fine here. , eat well and sleep well, I just received the admission letter today, and I plan to climb the Great Wall tomorrow!"

"Oh, are you going to climb the Great Wall? Mom hasn't been to the Great Wall yet. Mom will book tickets now. I'll let you and Chengzi lead the way tomorrow. Take Mom around the capital."

After finishing speaking, He Hua hung up the phone without waiting for Cheng Yuan to find a reason to prevaricate her.

He Hua felt bitter.

She doesn't want to climb the Great Wall, she just wants to see her son, see if he has suffered, and if he has been bullied severely.

How can He Hua rest assured that his son who has been raised for 18 years has been taken care of by himself, and he is no longer by his side all of a sudden?

What made He Hua even more angry was that his own bastard was still a heartless one.

Two months away from home, she was worried at home, but this bastard was wandering around all day long, and her circle of friends was full of where she went today, what food she ate, what milk tea she had, how happy she was, and she didn't think about her at all. The feeling of the old mother!

The son travels thousands of miles and the mother is worried, but the son has no heart!

-------------------------------------

Knowing that He Hua was coming, Zhou Cheng and Cheng Yuan immediately cleaned up the house.

When Zhou Cheng bought this house, he didn't plan on making it big. He changed the guest room into a study room. Instead of keeping the bed and wardrobe, he changed it into a desk and bookshelf.

After Cheng Yuan came, a desk was added to the study, and a few potted flowers were added. It was impossible for him to turn the study into a guest room without meeting all the conditions.

Zhou Cheng tidied up for a while, and felt that he couldn't make a name for himself, so he took out his mobile phone and called the sales department directly. After learning that there was an unsold hardcover house in the neighborhood next door, he dragged Cheng Yuan to look at the house up.

The people in the sales department knew that there was such a great god in their community. The real estate consultant was a beautiful young lady who politely took Zhou Cheng and Cheng Yuan to see the well-decorated house. The one I bought was more than double the size, more than 180 square meters.

In a place where every inch of land is expensive, a house of more than 180 square meters is not a price that ordinary people can afford. Zhou Cheng did not want to buy such a large apartment because he was an orphan and lived alone in a house of [-] square meters. More than enough, if the size of the house is too big, it would seem lonely to live in. Later, Cheng Yuan came, and the house with [-] screens was enough to live in.

Now that He Hua was coming to live, there was really no room for Zhou Cheng's house. In addition, the houses in this area were worth investing in, so Zhou Cheng paid the full amount directly.

All kinds of certificates are in the place where he lives. He has done it once before, and now he is familiar with it. In addition, he is the owner of this community, and the sales department has also given Zhou Chengxing a convenient way to sign various contracts. Once you have checked in and paid in full, you will receive your keys.

Zhou Cheng contacted the lock replacement company to install a new face recognition lock for the house. He took a selfie from He Hua's circle of friends, cut off the part of his face, and entered it into the lock's key. In the central control system, things are done.

Cheng Yuan took a selfie and entered his own photo into the central control system of the door lock. He tried in and out several times, as if he had just gotten a new toy. He said with Zhou Cheng, "Now this kind of The door lock with face recognition is good. If all of our neighborhoods are replaced with such locks, it will be much more convenient for my mother to collect rent in the future. I will directly set up a central control background and let tenants record their faces to enter. According to the rent paid Set up the authority, and let them automatically transfer money to my mother's account on a regular basis to postpone it, saving my mother from running around."

Zhou Cheng was stunned for a moment, nodded and said, "It's a good idea, technically it's not difficult to implement, I'll try it later, and after finishing the mesoporous system, I can help Aunt He relieve a little burden."

Cheng Yuan: "???"

"I'm just saying that casually, are you serious?" Cheng Yuan felt that the world was a bit mysterious.

Zhou Cheng rubbed the back of Cheng Yuan's head with a smile, "It's not difficult, let Aunt He install such doors, all the doors have built-in wireless chips, use the central control system to bind the authority of these wireless chips to All in one piece."

"You cook later. I will get out this central control system and make it a mobile app. After Aunt He comes, I will install it for her directly. All permissions will be opened. You can persuade Aunt He to let her go back. Just replace the doors door-to-door, and then update the information of the residents. There is a version for tenants and landlords, which saves time and trouble.”

Cheng Yuan suddenly became hypocritical, "Zhou Cheng, you are so kind to me."

Zhou Cheng: "..."

The muscular man with a height of over 1.8 meters five is acting like a baby online, this scene is simply terrible!

"Hanhan, stay away from me. If you think I'm nice to you, you can take care of washing underwear, socks, and cleaning shoes."

Cheng Yuan's face suddenly became quite indifferent, he gritted his teeth and squeezed out three words, "tui! Scumbag!"

Between Zhou Cheng and Cheng Yuan, cooking and washing dishes can be done together or in turn, but washing underwear, socks, and washing shoes are endowed with special meanings. Make a bet, whoever loses will wash the underwear and socks for the other party. If there is no underwear and socks to wash, the loser will have to be the son of the winning party for a day.

Out of ten times, Cheng Yuan lost eight times and nine times, but as long as he won once or twice, Cheng Yuan would be able to continue playing endlessly.

Zhou Cheng felt for a while that Cheng Yuan's face was getting thicker and thicker.

-------------------------------------

With the help of smart assistants, this APP is not difficult to write at all, just arrange and combine many program modules together.

Zhou Cheng likes to do things in one step, just like 'shop around'. The app he compiled for the first time was complained about the ugly UI, so he came to optimize and upgrade, and never used 'shop around' again. Home' spent thought.

The app he wrote this time is called "Homeland". It not only sets up a section for online rent payment, but also sets up a section for communication between tenants and a section for fault reporting. There are not many functions, but the core functions can be satisfied. It looks gaudy, with too many redundant and useless functions.

After the writing was completed, the smart assistant helped to check it from beginning to end. If no internal bugs were found, the APP package was processed.

When packing, the smart assistant also included the protection layer that Zhou Cheng used in the "Pollen Device Manager" to detect and kill viruses and Trojan horses and prevent software from being modified maliciously.

After finishing, Zhou Cheng put the 'Homeland APP' on his HOS mobile phone and ran it. No obvious problems were found, so he submitted it to the background of the HOS application manager.

The HOS launched by Huafen Group has become the mainstream operating system for mobile phones, computers, and smart devices in China. Because of its good compatibility, high fluency, and better ecology, various mainstream electronic devices in China have gradually upgraded their systems to HOS systems. .

Even those mobile phones for the elderly that can only make calls and send text messages use the HOS system, because the manufacturers of mobile phones for the elderly have found that the HOS system has a lower demand for hardware equipment, which can reduce the production cost of mobile phones for the elderly...

The HOS app store has also jumped from the original software store that only pollen device users can use to become the largest app store. Because of its higher compatibility, the number of apps under it has directly surpassed the fruit app store and the Android app store. .

Some software was tied to the fruit app store and the developer signed an exclusive licensing agreement. For these software, the person in charge of the HOS app store actively contacted the R&D personnel to develop and write alternatives to these software, so as to break the monopoly, and the effect was remarkable. .

Those software tied to the fruit ecology have lost a large part of their users, which has directly affected the revenue. Some software developers think that the behavior of the fruit group is the overlord clause, and they directly sued the fruit group to court...

A large amount of software floods into the HOS application store every day. In order to identify the good and bad of these software, the auditors set up a differential review sequence. Those APPs developed by developers who have established good cooperation and the voices in the application store Once the highest app is submitted to the review background, it will be reviewed first. Those apps developed by small developers or unknown developers need to queue up step by step, but the queue time will not be too long.

As soon as Zhou Cheng logged into the background, someone noticed that the reviewers were almost staring at Zhou Cheng as he uploaded the two apps to the background bit by bit.

The upload has just been completed, and Zhou Cheng is still filling out the application introduction, so the reviewers have already started testing the APP called 'Homeland' developed by Zhou Cheng.

Zhou Cheng finished filling out the application introduction, clicked 'Submit' within three seconds, the reviewer pressed the pass button, and sent it directly to the front page and pushed it on the front page, and even thought out the advertisement words—"Zc God once again Make a move, dedicate yourself!"

Looking at the name 'Homeland', people who don't know it thought it was some kind of social software. A group of people came in excitedly, and found that it was just a practical software for setting permissions based on electronic door locks, and they all retreated.

If this is a price comparison software for renting a house, many people must download it, but this is a software that can communicate with the landlord after renting a house, pay the rent and report for repairs, so few people are interested.

Even if they are interested, the landlords must be willing to install an electronic door for them!
