Rebirth of a technological power

Wednesday, April 1, 2020.

At three o'clock in the afternoon, the weather in Narcissus City seemed a bit hot.

Although it is only the first day of April, it is still spring in theory, and people in the north even wear thick clothes. However, the climate in southern Fujian is like this. There are only summer and spring. Summer is very long and spring is very short.

"Now let's take a look at the 3D printer!" Cai Jin turned the camera and pointed it at the 3D printer next to him.

The 3D printer is printing, and the legs of the mechanical dog are forming at a speed that is discernible to the naked eye.

"A mechanical dog requires four mechanical legs, and the mechanical legs are designed to bend backwards." Cai Jin turned the camera to the computer next to him again, and there was a picture on the computer.

This was designed by Cai Jin himself.

He is a senior student at Southeast University, majoring in robotics engineering.

The major of robotics engineering was a hot topic during Cai Jin's college entrance examination year.

Cai Jin filled out his application form for the college entrance examination, chose this major, and was admitted to Southeast University.

Originally, by this time, he should have returned to school, busy preparing for his graduation thesis, participating in spring recruitment on campus, finding a company to work as a worker in peace, and starting the happy life of 996.

However, the situation this year is somewhat special. College students are under great pressure to find employment. In order to ensure better employment for senior students and improve the employment rate, the school allows students to return to school at the end of May and conduct graduation thesis defense in late June.

On the seventh day of the Lunar New Year, Cai Jin started his daily work.

As early as last year, he became the UP host of Station B and the anchor of Douyin, specializing in the design and manufacturing of mechanical dogs and popularizing knowledge.

When he was studying at school, he would take some time to run these two accounts every day, assemble them on site, record some videos and post them on Station B and Douyin.

In this way, you can make money by selling mechanical dogs, and you can also make money by posting videos.

Of course, making money is not much.

What he makes is the lowest-end mechanical dog. This kind of mechanical dog only sells for 102 yuan on Taobao, and he only sells it for 100 yuan. After deducting the cost of 90 yuan, he only earns 10 yuan from selling a mechanical dog.

He can also make a bionic robot dog, which is slightly more profitable. A bionic mechanical dog costs at least 3,000 yuan, and the cost is only 2,000 yuan. A mechanical dog can earn a net profit of 1,000 yuan.

However, more people buy low-end mechanical dogs, and they are bought by parents and elders for children to play with.

As for the bionic mechanical dogs, if you can sell two of them a month, it’s considered good.

Therefore, Cai Jin can probably earn several thousand yuan a month, and tens of thousands of yuan on a good day.

He went home for the New Year and postponed his return to school until the end of May, so he spent more time on this.

As for using Douyin out of boredom, that's not what he does.

He always remembered that sentence: Look at a beautiful woman a hundred times, she is still not yours. Read the book a hundred times and the knowledge is yours! We must learn to grow up, young man!

"Next we assemble the mechanical dog. This assembly is very simple."

Cai Jin quickly assembled the mechanical dog. In less than five minutes, a mechanical dog was assembled.

This low-end mechanical dog can only do some simple actions, such as handstand, sit down, lie down, say hello, push-ups, sleep, and then add a few children's songs.

The remote control is also very small, with only nine small buttons, which a three-year-old child can play with.

"Okay, the mechanical dog is now assembled, let's go and test it!"

After Cai Jin finished speaking, he left home with two mechanical dogs and mobile phones.

He also has a bionic mechanical dog that he made himself. This bionic mechanical dog is much more advanced. He can operate it to get express delivery and buy things. Cai Jin has been working hard in the past few years.

During the most stressful period of the Chinese New Year, Cai Jin never left the door, and for all express delivery, he controlled this bionic mechanical dog to go out to pick up express delivery or send express delivery.

The reason why Cai Jin wants to test the mechanical dog is because he has to personally test each mechanical dog and send it to buyers, so that they can rest assured of the quality.

Of course, what everyone is curious about is often his advanced bionic mechanical dog.

Among fans, there are always some people with extraordinary hobbies.

For example, watching the mechanical dog slip on the wet tile floor and fall upside down, clumsily trying to get up and then falling again.

Or the mechanical dog fell into a low-lying area and struggled to get up but couldn't.

As a fan-favorite UP owner, Cai Jin naturally has to meet the requirements of these fans.

After controlling the bionic mechanical dog downstairs, the live broadcast room started to become lively.

Every time the bionic mechanical dog goes downstairs or up the stairs, it is always the most attractive.

All you have to do to get downstairs is roll!

Going upstairs depends on fate!

Even though Cai Jin was very good at maneuvering, it was still difficult to stop the bionic mechanical dog from rolling downstairs.

In the yard downstairs, Cai Jin operated the low-end mechanical dog and performed a few simple movements.

"Next, let's play stupidly!"

Benben is the name Cai Jin gave his bionic mechanical dog.

Bionic robot dogs are also a type of robot. Robot technology is called one of the greatest inventions of mankind in the 20th century. With its development, robots have reached an incredible level.

For example, a bionic mechanical dog costs three to four thousand, which is considered relatively common. A slightly better one costs thirty to forty thousand, and a more high-end one costs one million.

Cai Jin, a bionic mechanical dog, was reluctant to sell even though someone offered him five thousand.

Suddenly, Cai Jin trembled all over.

A translucent virtual panel suddenly appeared in front of him, making him jump back in fright.

Looking at the transparent virtual panel, Cai Jin was surprised at first, and then fell into ecstasy.

Could it be that he was selected by the legendary system?

He has read online novels.

He once complained crazily that he was not a time traveler and had no system. It was not that difficult for this salty fish to turn over.

Those who have been reborn through time travel without a system cannot defeat the natives, let alone ordinary people like him.

Everyone wants to be Jack Ma, Xiao Ma Ge, Dong Ge, Zhang Yiming, but no one really becomes one.

After swallowing, Cai Jin hurriedly asked: "What functions do you have in the system?"

There was no metallic sound or any echo.

But something has changed on the virtual panel:

[Item: Entry-level children’s intelligent mechanical dog]

[Experience value: 1/100]

[Optimization point: 1]

? ? ?

Cai Jin's mind was full of questions.

This system of mine is a bit stupid!

It doesn’t even have smart voice.

Cai Jin touched his bionic mechanical dog again.

There are another changes on the virtual panel:

[Item: Entry-level intelligent mechanical dog]

[Experience value: 5/1000]

[Optimization point: 1]

Cai Jin's eyes widened, this is...

With some vague speculation in his heart, Cai Jin reached for his phone.

Sure enough, the virtual panel has new changes:

[Item: Huawei mate30 Pro]

[Experience value: 0/1000]

[Optimization point: 1]

"Dear friends, today's live broadcast ends here. If you like it, you can click the link to place an order."

Cai Jin hurriedly ended the live broadcast and returned with two low-end mechanical dogs.
