But he didn't think about what to delve into in the past, making friends is not a business.

If you deliberately have some purpose, friends won't be able to do it, so it's much more comfortable to interact with each other with a normal heart.

After a little silence, Tu Fei raised his head and replied seriously: "Sister Xinran, I can't give such a big promise now, I can only promise to do my best to give them a good future." ”

Jiang Xinran showed a smile on his face and nodded, "That's enough, I'm afraid you will use them as rags." ”

"How is it possible, Sister Xinran, I'm this kind of person!" Tu Fei said pretending to be angry.

"Hee-hee, I know you're not such a person, I'm not reminding you!"

"Well, Sister Xinran, I'm going to go to the software company later, why don't you go home first, I'll just find a hotel and sleep in a hotel by myself at night." ”

Jiang Xinran nodded, "Okay, I'll help you implement the office later, it's near here, it's very convenient, and you don't need to stay in a hotel, you can call me when you're done, and I'll take you to my room." ”

"Ah, this ...... It's not good. Tu Fei couldn't help but swallow a mouthful of spit, thinking about some messy things in his heart.

"What do you think, it's a small apartment I bought myself, you live there, I'll go back to my own house. Jiang Xinran couldn't help but poke his head with that finger.

"Oh. Tu Fei exhaled, feeling slightly disappointed.

After coming out of the noodle shop, Tu Fei took a taxi and contacted a mobile app development company that he had already contacted, ready to customize an app.

He now has to save money, and everything must be arranged according to the principle of "picking the door", and he has done a very full understanding of the work before he came.

There are several main impacts on the cost of mobile app development.

The first is the difficulty of developing a function of the mobile app

Functions are the core of an application development, generally applying complex functions and simple functions, such as storing application functions are more complex, but simple enterprise product display application development, functions are relatively simple. Also need to look at the level of difficulty complexity support on the server.

The second is the scope of work for the development of enterprise mobile app application software

If you have done a good job of designing, making interface materials, preparing data, and bringing your own account to complete the online application, it will be cheaper to only commission development, on the contrary, if you entrust new ideas and function planning, the cost will increase a lot.

The third is the quality requirements of the mobile app application of the mobile phone client

The same App, different quality and price will definitely be affected, and there is also a problem of upgrading the App, this upgrade is a lot of work to do, whether to bear the responsibility of upgrading and improving will also affect the price.

A simple life application App, does not rely on the background, even the design + development is entrusted, direct development period = 2 weeks, plan + communication + testing + modification = 2 weeks, about 1 month before and after, depending on the quality of the team, the price should be 30,000 ~ 100,000; complex front and back office App, find a reliable team, the price should be 100,000 ~ hundreds of thousands, the cycle is about 2 months ~ 3 months.

However, he has a system to optimize, and the intermediate steps can basically be omitted, of course, it will not take such a long time.

And the most important thing is that although he is ready to rely on the app to operate, the requirements for the app itself are not too high, so he simply outsourced it, which can save time and energy.

It's a big deal to replace it directly when the time comes.

And the most important thing is that Tu Fei's eyes have never stayed on the operation of this app, which is only the first step for him to do black technology blockchain, and it is also a cover and protective color.

I talked to their development engineer and stayed in the development company all afternoon until the evening, and when I came out, it was almost dark.

Hesitating to call Jiang Xinran, he looked at the time and saw that it was already seven o'clock in the evening.

It is estimated that she has already finished eating by this time.

Forget it, let's just eat some casually outside alone.

Thinking like this, Tu Fei glanced around, and saw an open-air restaurant on the side of the mountain not far away, so he walked over.

As he was turning the corner, he suddenly noticed a group of bear children frolicking around a dirty beggar in the alley around the corner of the street, and threw things at him from time to time.

However, the most surprising thing was that the beggar's face was covered with hair, just like a famous hairy child a few years ago.

Strange, is this another atavistic human?

"Go home whatever you want. ”

Roared at the bear children to scare them away, and after seeing that the beggar was nothing unusual, Tu Fei was about to leave, but at this time, the bear child who was originally yelled away by him suddenly appeared out of nowhere, holding a slingshot in his hand, and popped a stone at him.

The distance was so close that Tu Fei didn't even have a chance to hide in a panic, and watched as the stone shot towards his eyebrows.

At this thrilling moment, the atavistic ape-man, who was still not far away, suddenly jumped up from the spot, instantly jumped out of three meters away, and blocked Tu Fei in front of Tu Fei with a mineral water bottle in his hand.

Just listen to the "poof", the stone just hit the mineral water bottle and fell to the ground.

It took three seconds for Tu Fei to come back to his senses, and he was afraid for a while, if this stone was shot in the eye, he didn't know what the consequences would be.

Seeing that there was almost an accident, the bear child dispersed with a bang, and Tu Fei didn't bother to chase after him, so he turned his head and looked at the "atavistic ape" in front of him.

The glimpse just now, he seemed a little scary in retrospect.

Rushing over from a distance of three meters, he could also prepare to block the fast-shooting stones with a mineral water bottle, which was not something that ordinary people could do, coupled with his appearance of "atavistic ape", Tu Fei couldn't help but think of the same thing as Tang Tang.

Could it be that this weirdo is also like this?

Try to say hello, "Hello." ”

The atavistic apeman glanced at him and nodded slightly, but did not speak.

Taking a slight breath, he asked in the most peaceful tone possible, "That...... What's your name and where are you?"

The atavistic ape still did not speak, and turned to leave with his head bowed.

Tu Fei frowned, saw the restaurant next to him, and asked with an idea: "Are you hungry, I'll treat you to dinner." ”

Sure enough, after hearing this, the ape-man instantly stood still, turned around and looked at Tu Fei's Adam's apple moving, and a hoarse voice came out of his throat, "I eat a lot." ”

Tu Fei couldn't help laughing, patted his chest and said, "It's okay, I have money, I can afford it." ”
