The simple software framework Chen Fan relied on the speed of his hand against the sky and finished typing on the computer.

There is a piece of software lying on the computer menu

The name of the software is weird

Because it's called "Open the Door ~ Daddy ~"

Smack×n

The sound of Chen Fan's fingers colliding with the metal keypad came from the air again......

The web version of the entrance is completed

The Android and iOS mobile versions have also been completed

This is followed by the fee section

Think twice

Chen Fan formulated the charging standard for this software

Five yuan a day, 150 yuan a month, and the VIP price is 120 yuan.

Chen Fan felt that this charge was very reasonable.

Because of the high school make-up class, 150 yuan for a class, is the price of the college student to give you a make-up class, if the normal high school teacher makes up the class, at least 300 yuan a class, of course, this is a one-to-one, one-to-two price, if you make up a class together, that is 50, 60, or 70, 80 yuan a class.

There are eight days in a month, even if a class is 50 yuan, a subject is 400 yuan, you must know that there is no thesis theory, you need to make up the money for 6 subjects, and the monthly make-up fee alone is 2400 yuan.

Once the students approve of Chen Fan's website

There are a total of 30 million high school students in the country, even if 5 million people use it, a person will have a net income of 600 million yuan a month for 120 yuan a month!

This is not counting the cheats money that Chen Fan expected

What cheats? It is the sorting out of some single-subject test sites.

For example, there are 130 college entrance examination questions in mathematics and all of them, hundreds of derivative question types.

You don't know this, who sorted it out for you?

This one has to be a few thousand dollars smaller, right?

It's more useful than how many lessons you make, because no matter how many years a teacher has been teaching, he won't be able to sort it out, and he doesn't have the energy.

Of course, Chen Fan has only done a good job of each version of the framework now, and the big data in it has not been filled in well, and Chen Fan has not thought about how many plates to set up and add some interesting games.

Looking at the time again, it's late at night again.

Chen Fan rubbed his shoulders

The shoulder muscles are a little stiff

This is also him, his body is like mercury, and his cultivation has already reached the realm of transformation, otherwise ordinary people will not be able to withstand it.

But I'm not in a hurry about the software, Yingzi's girl didn't come today, it should have scared her mother.

Chen Fan went to wash it briefly, then lay on the bed and sleep!

A few more days passed, and it was another Friday after school.

Dinner table

Song Qian found the topic: "Xiaofan learned programming, how is his learning?" ”

"Well, I've learned it." Chen Fan said calmly, without affecting the speed of eating.

"Are you teaching yourself how to code? Still learned? Qiao Yingzi asked curiously.

"Well, the software is almost there, but it's just a big database to build." Chen Fan nodded calmly.

"I'll go, big brother, please leave a way for us ordinary people to live, do you know that you are simply too perverted sometimes!" Qiao Yingzi is called envy, jealousy and hatred.

"Yingzi, how do you speak!" Song Qian couldn't stand it.

She knew that Chen Fan had learned programming entirely for her own girl, and she was eager to tell the truth directly, but Song Qian held back.

Once she says it, I'm afraid it will greet her own girl who takes the initiative to give her arms!

When the time comes, if these two little ones are happy and create two little people for her, she will have no place to cry!

"Hmph~" Qiao Yingzi glared at Chen Fan.

She is now the child she picked up later, Chen Fan is her own, she can't say that Chen Fan is bad at all, and her mother will have five words to follow.

It's all wool, and my mother protects Chen Fan, who is ruthless!

So Qiao Yingzi only dared to express her dissatisfaction with her voice, and did not dare to use words.

Meal

Song Qian looked at Qiao Yingzi who was leaning on Chen Fan's back with a pillow.

I kept reassuring myself in my heart, I didn't see it, this is normal, it is a matter of time or time...... Recently, Qiao Yingzi always likes to lean on Chen Fan.

The key is that Song Qian can't say anything yet!

Otherwise, how to empty the shopping cart!

Take other people's hands short, eat other people's mouth short!

What she didn't know was that Chen Fan had already emptied Qiao Yingzi's shopping cart......

I didn't pay attention to the impact at all, I was chatting with my mobile phone in my hand, and the posture of leaning back was completely subconscious.

Song Qian felt more and more that Qiao Yingzi didn't belong to her anymore!

"Xiao Fan, what have you been busy with these two days?" Song Qian sat next to Chen Fan, looking at the perverted hand speed, there was a mess of garbled characters on the computer, and she couldn't see what Chen Fan was doing at all.

She wasn't shocked, she was used to it these days.

"My software is pretty much designed! I am now in the process of populating the databases of each section and building the structure of the various small units. Chen Fan rarely stopped and explained.

"Aunt Song wants to take a look?" Chen Fan's bland words exuded a strong confidence.

The two have an agreement

Chen Fan designed the software, and Song Qian no longer objected to Qiao Yingzi and Chen Fan hooking up.

"I'll see." Song Qian also wanted to see Chen Fan's achievements in the past few days.

"Okay." Chen Fan simply pressed a few buttons, and the computer returned to normal mode.

Then he handed the computer to Song Qian

"That software is your learning software?" Song Qian looked at a lot of scattered software on the desktop.

"It's the logo that Yingzi is!"

Chen Fan said that Song Qian's psychology was put on hold again.

"The name is Open Door ~ Daddy? What is this shaming? Song Qian complained.

She thought it would be a romantic name.

"Mom, you don't understand, it's popular now, are you done with this software?" Qiao Yingzi didn't know that Chen Fan had done such a big thing, but she knew the stalk of "Open the Door ~ Daddy", which came from her father.

Although it is not very romantic, the logo is her avatar, and the word "open the door ~ Daddy" unexpectedly poked the sweetness in her heart.

"At present, I have only completed mathematics, physics and chemistry, all the high school knowledge and core test points of these three subjects, as well as the example questions of the annual college entrance examination, as well as the evolution of body types and the new question types that have been synthesized independently!" Chen Fan was very excited, in other words, his software can already be put on the market!

Song Qian was not bluffed, whether it was useful or not, I had to go and see it for herself!

Open the website

The fresh, simple drawings and the ability to automatically block all ads make her refreshing, in short, very comfortable.

Song Qian is a physics teacher, and the click is naturally a physics section

One enters the choice of high school physics

She was already shocked

Because she saw that there was a section of university physics on it, but unfortunately it was not open, and it was locked by a chain!

This kid is not small

sighed in her heart, and Song Qian was shocked again.

Because clicking on the physics section is not a table of contents, nor is it a word, but a very detailed knowledge chain diagram.

This knowledge chain is very powerful, using a map mode, and there is a navigation map in the upper left, which will guide you, allowing you to accurately locate the knowledge you are looking for, and after clicking on the knowledge, you can link to the target.

Song Qian clicked on a few, each knowledge point is detailed in her opinion, and the most important thing is that each knowledge point has the corresponding college entrance examination questions over the years, as well as mock questions from major colleges and universities across the country, fill in the blanks, select, calculate, everything applied to the knowledge point, will pop up!
