"We are for the good of humanity, to preserve everything in this world, and we can legally allow unscrupulous people! If you understand it with normal thinking, we belong to the third base! ”

Civil science, or the scope of human conventional science, all the things that human beings need in their daily life, to carry out a series of scientific experiments and inventions, such institutions, can be divided into the category of the first base, there is science, there is no base.

For example, mobile phones, computers, or some mechanical equipment, ordinary civilian engines, etc., all belong to this level.

And those high-precision instruments, high-tech research, and all scientific research institutions that serve high-level secret organizations, such as research institutes, and institutes of science and sciences, are so worried, they belong to people who know about it, but they don't have regular contact, or even don't have the opportunity to contact it, there is science, and there are incentives, and this is the scope of the second base.

Then the third base is unknown to ordinary people, or even does not exist, but this non-existence is just an illusion created in order to better serve mankind.

"Obviously, child, we exist, you are still young, there will be opportunities in the future, I will also show you people who can transform, or spit fire in their mouths, or even lift a locomotive with one hand!" Zhang Yao smiled proudly.

As everyone knows, in the past, when I was studying, the school allowed students to use lazy electronic calculators for various mathematical calculations, which was more convenient.

However, Zheng Ying said that the family in which she lives is very poor, and other people's children have mobile phones in elementary school, and when he reaches junior high school, he can't even afford a calculator for a few yuan.

So he was very stubborn and built his own, all made of wooden gears, a mechanical calculator the size of a computer console, which could only do addition and subtraction.

He thought he was smart enough to attract the admiration of his classmates.

But they ridiculed him, thinking that this kid was too stupid, and used some sentence chisels, carved some wooden gears, and made a mechanical calculator that could only calculate addition and subtraction.

Not only is there nothing glamorous about this, but it makes people think that he is too old-fashioned.

"Your calculators are all for electricity, and when there is no electricity one day, you are not as good as my pile of wood." Zheng Ying said angrily at that time.

Later, he built a wood-geared mechanical calculator the size of two desktop computer hosts designed to multiply and divide.

And the classmates brought ridicule, saying that you can't count things with decimal points at all.

Zheng Ying waved her hand: "Why do you have to count decimal things?" If you say that you use 10 to remove 0.5, and directly use 100 to remove 5, don't you men stick to that point? ”

"Our calculator can remove 0 by number, or multiply by 0, can you have that pile of rotten wood?" The classmates who laughed at him immediately retorted to him.

However, in Zheng Ying's opinion, they are already stupid to the point where they can't communicate with themselves, since they are already 0, there must be something wrong, it's okay to be idle, to add, subtract, multiply and divide the number zero, does it make sense?

Of course, all this is his experience, and Zhang Yao is more willing to rationally analyze how smart this person's brain is.

Because mechanical calculators, even if they are made of wood, can do addition, subtraction, multiplication, and division of numbers up to 10 digits, which is much more reliable than electronic instruments.

Really just like Zheng Ying said, there are still weapons in this world that can destroy the power system, such as high-voltage electromagnetic pulse.

And everything in human society, as long as it has a little bit of civilian scientific and technological content, is almost inseparable from "electric energy".

All kinds of engines, in addition to electricity, are fuel, or steam power, even the so-called solar or nuclear energy, so far, human beings have only converted it into electricity to use.

Could it be that electricity can really rule the world over all high-tech operations?

Zhang Yao didn't go, thinking deeply, he was just the boss who led the third base, and he was not a scientific researcher in the real sense.

And what he fancied was a child with only a junior high school education, so he made a mechanical calculator by hand.

This should be called talent.

"What other interesting things have you done?"

When Zhang Yao first met Zheng Ying, the medical staff injected him with vitamins and glucose, and when he woke up, they began to question him.

Zheng Ying smiled a little embarrassedly and said, other male classmates can use money to please girls, but I don't have money, so I can only use some rags to make some music boxes for those girls.
