Until he was 3 years old, Yi Rongdan was still tormented by his black-bellied father.

As a retired mechanical maintenance soldier, the military rank is quite high, and Yi Lin has enough subsidies to maintain the normal life of the family, but Yi Lin, who can't stay idle, still starts his own business. The old business, mechanical maintenance.

Nuoqi Star is an agricultural star, sparsely populated, the planet has a wide land, suitable for growing crops and grazing, there are only three human settlements on the whole planet, and the rest of the locations are agricultural areas.

Yi Lin was scornful of repairing agricultural equipment, but Ellie's mother said: "I don't really want to leave Nuoqi Star, it's very comfortable and suitable for life, and the pace of life on the main star is too fast. ”

Good husband Yi Lin can only compromise, it is much better to do a little agricultural equipment maintenance than never do this business again.

The townspeople are very welcoming about this.

Nuoqi Star is far away from the main star, the traffic is unusually inconvenient, every time you have to ask the maintenance engineer of the commercial star to come, if you need to replace the parts, you have to go back to the company to deploy, back and forth is more than a month, and the strike of the equipment means that the production chain is broken, and the crop growth is broken for more than a month, which means that this year's harvest will not be good, you can only borrow other people's equipment for temporary use, but you can't rent it for a long time, at this time Yi Lin's arrival solved most of the problems. Especially Yi Lin, a former maintenance soldier, he can also produce accessories independently.

The opening of the Yilin maintenance shop was unusually smooth, and the town neighborhood committee directly approved a piece of land in the center of the town for him to use, and the basement was also built with soundproof materials, and all he did was to order a set of machine tools for parts processing and get a certificate of conformity.

So Yi Rongdan's life has also become colorful.

There is no kindergarten in Nuoqixing, and there are not twenty children in the whole planet, and now every household has a household machine, and there is no need to build a kindergarten here, but there is a primary school in Nuoqixing.

Three-year-old Yi Rongdan eventually won the right to go to primary school.

For putting such a young child in primary school, not only Ellie's mother, but also the principal Tanzan is not very relieved. The school's teachers are not very good, most of the time they use distance teaching, the main star special teacher synchronous teaching, although the children are learning together, but this kind of teacher is impossible to supervise, such a small child in front of a group of seven or eight years old children, very eye-catching, so Tanzanite approval, go to school in the morning, go home in the afternoon, only four hours, the school assistant teacher can still take care of it.

In the past few years, Ellie's mother's volunteers have become more and more dedicated, and she finally found other meanings in life besides housewives, because of her excellent performance, Ellie's mother has officially become a staff member of the neighborhood committee from a simple volunteer, and even if she becomes a civil servant in the Lanstrloy Federation, she will also receive a salary, but this also means that she can no longer fully devote her time to Yi Rong Dan.

As a result, Yi Rong Dan was completely destroyed by the father of the Belly Black Lord.

Facing steel and metal every day, Yi Lin couldn't distract himself from the mind to see what Yi Rongdan needed, but fortunately, Yi was not a complete child at the age of three, and he also knew what could not be touched in the factory, but Aili, who occasionally came to visit the class, went crazy.

Yi Lin, who has been educated, finally understands how to take care of the child, and after observing for a few days, his son is still very well-behaved, and Yi Lin found an excellent way to take care of his son at work, that is, to explain while working.

Yi Rongdan's childhood was immersed in "Theoretical Foundations of Maintenance Equipment", "Physical High-end Motion Forms", "Mancheras Kinematics" and "Circuit Analysis".

For this kind of life, Yi Rongdan expressed his unwillingness to accept it.

Oh my God, he's a good liberal arts student, even if he has enough IQ to understand these things every day, his head will hurt!

And Yi Lin's father is also an unusual headache, his son, who knows all kinds of theoretical knowledge, is the head is the way, but even the most basic electronic alarm clock can't be disassembled and installed as it is, please, even if he doesn't know this knowledge when he is five years old, he can assemble a complete starship model, okay! Why can't his son do it! Could it be that the brain of the science idiot of the hereditary Ellie? But all my sons do!

Anyway, as a liberal arts dog, living surrounded by science houses is extremely difficult.

That's right, it's the siege. The next-door neighbor, Grandpa Bernie, is also a science house.

Bernie has a group of optical brain computer rooms with excellent performance, and now people use simple optical brain chips, but in this year, the huge computer room is also stored, but the role of this computer room is also unusually unique, generally used for starship master brain and national interstellar network maintenance, as an old man who retires in Nuoqi Star, Bernie will have such a computer room, it is simply impossible.

Yi Rong Dan was able to know this kind of secret, or because of his age.

When people are old, there will always be some strange habits, Bernie usually loves to flirt with beautiful women, what he loves most is to show off to other old men and old ladies what rare things he has gotten, and there are always some couriers to mail him, and most of his capital comes from these, but the thing he is most proud of is the computer room.

This computer room is a secret, of course, it is impossible to say it openly, and Yi Rongdan, who is young and should not have any memory, has become the object of his confiding.

Every time Ellie didn't have time to take care of the child and sent him to Bernie, the merry old man would secretly enter the underground secret room, hold the child, open the computer room, and tell him about the performance of the optical brain, the connection speed, and the backdoors of major websites. Bernie thought that it would be safe to end this unnecessary behavior before Yi Rong Dan could remember, but he didn't expect that Yi Rong Dan had a really good memory.

Hearing and seeing, Yi Rong Dan also understood what some of the codes flashed by the light brain meant, after all, he was not a real child, sitting there in a daze was not the right way, when he was two and a half years old, he sat behind Bernie and watched him enter the code, and then very accidentally found a loophole, and the long-term laxity made him completely forget about hiding.

"Bernie, there was a loophole there just now, was it a trap you left for the other party?"

Bernie replied casually: "Oh, of course, little baby, how could I make such a mistake with such a good skill?" ”

Then Bernie almost burned the console out of a distraction.

Two and a half years old, Bernie was of course very surprised to be able to understand the meaning of the code at this age, although he was troubled by the secret being known, but it also meant that he had a good seedling that could be □□! As long as you pull this seedling into the water, it doesn't matter how much you brag about it, okay! You can also tell the other party about the classic cases you have fought against, and if you teach it well, you can also hand over this child to the Security Bureau, which is just a few in one fell swoop!

At this time, Yi Rongdan didn't know that he had been targeted by the former ace agent of the Security Bureau, and he had been forced to memorize the code for two years.

In addition to teaching him hacking techniques, Bernie also taught him many national etiquette, future versions of psychology.

Although these were already in the hands of Erong Dan before he was reborn, in the future, the situation became more complicated.

Between countries, because of the vast interstellar space, it has become more and more different.

Some countries are tourist stars, because of special historical reasons and geographical locations, there is no military force and completely independent existence in the interstellar.

Some countries have a large number of minerals, but they have no agricultural foundation, and basically rely on the export of minerals to develop their economy, and rely entirely on imports for food.

Some countries do not allow men to enter, and some countries maintain polyandry or even polygamy.

Diplomacy has become more difficult because of the distance between time, culture, and geography.

Yi Rong Dan was even more excited.

Knowing that Bernie was teaching Yirong Dan those things, Mina couldn't sit still.

Mina is an old nurse, a nurse with a certificate in advanced pharmacy. She is one of the few townspeople who knows Bernie's identity, and she also settled here in pursuit of Bernie, and Mina likes Bernie. That dude.

No matter what she thinks about Bernie, Mina usually likes to quarrel with him just as much as Huanxi's enemies, and even compares with him, what gifts the juniors send over, what school they are admitted to, and how many credits they take, all of which have become the object of their discussion. And Yi Rong Dan has also become one of them.

"Dandan managed to steal a copy of Pute's text today," Bernie said calmly.

"Ao, what is this, Dandan successfully made a Pinos reagent today, a first-class product!" Grandma Mina, that color is second-class good.

"Hehe, what's the use of reagents? Don't drink it if you're not sick! ”

"You have the ability not to catch a cold! Don't ask me for allergy shots during pollen season! ”

Yi Rongdan wants to cry without tears, he is a liberal arts student, a liberal arts student, a liberal arts student, and important things are said three times!

But fortunately, in this qiē, the black-bellied father didn't know at all, otherwise he would probably blow up: Why can everything they teach be made, and what I teach him can be out of shape when he makes a part? Why? Am I not teaching well? Or does the son not have this gene? No, the theory is known, why is the actual operation rotten into slag, why!

Eh, Yilin's father, no one knows about this.

Learning endlessly, Yi Rong Dan fully knew what this word meant, and there were more unknowns left for him to explore in the vast interstellar space. Learning, it's really TMD fun.

That's the roar of a liberal arts student.
