Lao Zhu climbed up step by step from the bottom, and after going through personnel over the years, he actually felt quite profound about Zhu Yuan's argument of 'complex world'.

After a sigh, he turned to the nuclear energy-related information in front of him.

Just a moment of reading, Lao Zhu only felt ...... Another door opened.

And, unbelievable.

I couldn't help but look up at the young man opposite, looked down again, and looked up again after a while, with a slight expression of 'I don't read much, don't lie to me', sighed and said, "This ...... It's really ...... 'book from heaven'. ”

As he spoke, he flipped back to a formula again.

e=mc^2。

This is the once famous Einstein mass-energy equation.

For each of the symbols, Zhu Yuan has made detailed annotations.

For example, the speed of light represented by 'c' can travel 600,000 miles in 1 second, and this 1 second is only a fraction of a ten-thousandth of a 12 hours in a day. Such a large magnitude has to be squared a little more to combine with the weight of the substance.

Lao Zhu only felt that this kind of 'energy' was the size of a grain of rice, wouldn't it be ......

The mind stops here.

Because ...... 'just' how...... Lao Zhu couldn't fantasize anymore, so he could only look at the other side.

Zhu Yuan understood Lao Zhu's feelings, and took the initiative to explain: "Ancestor, if it weren't for the fact that human beings really realized the use of nuclear energy hundreds of years later, at first glance, I would only think that I was making things up. However, one of the most powerful pieces of evidence at the moment is outside, it happens to be a sunny day today, and you can see the sun when you look up. The sun is a big fireball that is always undergoing nuclear reactions, and the amount of solar energy received by our earth is only one billionth of what it releases, and it has nourished all things for billions of years. As I said before, most of the energy on Earth comes from the sun. Coal, for example, was buried in the ground hundreds of millions of years ago by forests that grew with solar energy, and it took shape after the vicissitudes of life. ”

Lao Zhu breathed a sigh of relief and reluctantly nodded slightly.

Truly.

The sun hung outside, and he couldn't believe it.

Then there was another hesitation.

You must know that when the globe was first obtained, Lao Zhu was reluctant to show it to his sons. It was not his father's hiding of his secrets, but he was afraid that it would affect the minds of the princes, and it was only after Zhu Yuan's persuasion that he figured it out.

At present, this nuclear energy-related knowledge, according to the twenty-third grandson of his baby, will inevitably have more impact on the 'world view, outlook on life, and values', so Lao Zhu doesn't know if he should let Zhu Yuan teach the children today.

Perhaps, wait?

Thinking so, Lao Zhu went through the information in front of him again, and there were some inappropriateness, and asked the young man opposite: "Yuan'er, these are these...... I just feel ...... Afraid it's not a good thing? ”

"The feeling of the ancestors is right," Zhu Yuan did not deny: "I actually didn't write a lot of knowledge related to nuclear energy, so I can only tell the ancestors." Because, once ...... Hundreds of years later, the earliest use of nuclear energy by human beings was made into weapons, called 'nuclear weapons'. ”

Lao Zhu had a faint feeling just now, and sure enough, he was confirmed, and subconsciously asked: "What is a nuclear weapon?" ”

"Ancestors should pay attention to the mass-energy equation, which is the key to nuclear energy," Zhu Yuan said: "Nuclear weapons made on the basis of the mass-energy equation, simply put, 1 kilogram of nuclear fuel, the energy released by the instantaneous explosion is equivalent to the power of tens of thousands of tons of explosives." For example, one is Japan, next door to us, World War II...... At that time, because Japan refused to surrender, it was dropped by the United States on the other side of the ocean with nuclear weapons, which had just been developed and the technology was not yet mature, but it was only a nuclear bomb with a yield of 15,000 tons, which directly destroyed a large city with a population of hundreds of thousands, and more than 200,000 people died before and after. ”

Speaking of this, Zhu Yuan explained a little what 'yield' is, and then continued: "Ancestors, 15,000 tons of nuclear weapons are only a very small kind of nuclear weapons in the early stage of nuclear weapon development, and the nuclear weapons that exploded on the earth later have a maximum yield of up to 50 million tons, which was also developed by the 'Soviet Union' that I also talked about with my ancestors, and the original planned yield was even larger, with 170 million tons, because the power was so great that it could not find a suitable test explosion site, it could only be reduced to 50 million tons. That nuclear weapon exploded in the open Arctic region, and even distorted the orbit of our earth around the sun, which can be called devastating, and the ancestors can imagine its power. In short, when nuclear weapons were developed, many people began to worry that once a nuclear war broke out one day in which various countries threw nuclear weapons on each other, our planet would be destroyed, and mankind would be wiped out. ”

Lao Zhu felt that he was listening to the 'Book of Heaven' again, and it was a very, very terrifying page in it.

After a little consideration, Lao Zhu quickly said: "In this case, don't tell them about it, I'll burn these later." Yuan'er, you also bury these knowledge in your heart forever, it's best not to be in this world. ”

Zhu Yuan shook his head: "Ancestor, I thought about it at first, but I'm afraid it won't work." ”

Lao Zhu was puzzled: "Why?" ”

"Because the sun hangs there," Zhu Yuan gestured outside: "Ancestor, there are always people in this world who look up at the sky and think, what are they, the sun, the moon, and the stars?" In ancient times, people could not understand them, they could only mythologize. However, when society gradually develops and science continues to advance, one by one, the truth will always be studied. Like I said, hundreds of years later, it's actually common sense that children know. ”

Lao Zhu was silent for a while.

Zhu Yuan continued: "What I just said is only on the one hand, the ancestors, on the other hand, we have to talk about the 'study of economics', the continuous development of human society, the root of which is the continuous improvement of productive forces. How to improve it, one of the fundamentals is the use of energy. Just looking at the formula of the mass-energy equation, the ancestors should understand that compared with our firewood, charcoal, and even oil burning in the future, nuclear energy is the key to promoting another qualitative change in productivity. The traditional energy sources on earth, whether coal or oil, are actually limited, and when they are dug up, they are gone, because it will take hundreds of millions of years to form again. Nuclear energy, for us human beings, is almost unlimited, inexhaustible, and inexhaustible. ”

Lao Zhu's expression was deliberate.

Zhu Yuan also continued: "Finally, there is another question. Ancestors, next, we enter the industrial age, perhaps, the ban on nuclear energy, can allow us to stay in the primary industrial age. The problem is that other countries on this planet are not going to stay, and if they get ahead of us and have access to nuclear energy in advance, it will be catastrophic for us. At this point, let's just say that the pattern of the world before the arrival of Yuan'er, several major powers, including China, all possessed nuclear weapons and deterred each other, so a balance was formed. In the era when China did not have nuclear weapons, the Soviet Union and the United States at that time, when they clashed with us, all considered using hundreds of nuclear weapons to completely destroy our country. It wasn't until we soon developed nuclear weapons that we avoided the fate of the destroyed country and the annihilation. Ancestors, imagine now, when you and Zhang and Chen fought for the world, if both of them had the nuclear weapons I said, and we didn't, could they not use them? ”

Lao Zhu bowed slightly.

Zhu Yuan said: "So, ancestor, my idea is that not only can we not ban it, but we will ...... in the future Oh, we probably can't see it in the past two generations, in short, we must vigorously develop this science, develop nuclear energy application technology in advance, and firmly grasp it in our own hands, and have absolute technological advantages. The reason why we were able to form a balance situation in which many countries possess nuclear weapons was that the technology spread so rapidly that it was not many years before everyone could do it, and no country had an absolute lead. This time, we can do this if we lay out many years in advance. When the time comes, other countries ...... Whoever dares to touch these things will destroy them in advance. ”

Lao Zhu finally nodded, but shook his head again: "This matter still needs to be carefully considered, well, you will ...... later." Just tell them about it superficially, don't go too deep. ”

"Yuan'er understands."

Lao Zhu waved his hand: "You go, I'm here...... I'm thinking about it. ”

Zhu Yuan agreed, but he didn't get up immediately, but asked about another thing that the government and the opposition have been paying attention to recently: "Ancestor, how is the war in Shuzhong?" ”

"I'm afraid that the Qinling Mountains will have another wind and snow to affect the supply, I will let Yuchun stock up on more grain and grass in Bazhou and then enter Shu, and the launch time is set for the beginning of next month," Lao Zhu did not hide these military affairs in front of his baby twenty-third grandson, explained simply, and said with a smile: "It's still your credit, this year I transported any grain and grass to the north, I have ordered to transfer 500,000 stone of grain from Bianliang to Chang'an, and all the original grain in Chang'an will be sent to Qinling, which can always ensure that Shaanxi is safe." ”

As the saying goes, 'the army has not moved, the grain and grass go first', Lao Zhu's arrangement is indeed a safe policy, and even the matter of the possible shortage of food in Shaanxi in the winter after the army action is taken into account.

As for their own merits......

Enough is enough.

Don't do that.

Thinking like this, Zhu Yuan thought of one: "From Bianliang to Shaanxi in winter, I'm afraid the waterway is inconvenient, right?" ”

Lao Zhu obviously understood what Zhu Yuan was asking, nodded and shook his head: "Wen Hui's letter also said, but some sections of the river are frozen, but it doesn't matter, the ready-made galloping road, and walking on the ice is faster than on land." Incidentally mentioning a certain adopted son, Lao Zhu couldn't help but be curious: "Wen Hui...... How was it ever? ”

】

Zhu Yuan knew that the 'Wenhui' that Lao Zhu said was He Wenhui, who was only 27 years old this year, and was already the commander of the Henan Province Zuo Cheng and the commander of the Henan Metropolitan Envoy, who had previously served as the deputy of Hu Tingrui all the way to Jiangxi, and was now responsible for guarding Bianliang, and then looking at the word 'Wen' in his name that is the same as Zhu Wenzheng and Li Wenzhong, you can imagine Lao Zhu's closeness and trust.

didn't expect Lao Zhu to suddenly turn here, Zhu Yuan paused, and still said: "Yuan'er doesn't remember much, I used to ...... It seems that he died early due to illness. ”

Lao Zhu: "......"

It's a good thing to ask.

Inexplicably, he was a little disgusted with the baby bump of a certain 'unknown prophet', and waved his hand to drive people away: "Go, there is still ...... You have to worry more about medicine. ”

Zhu Yuan agreed, got up and said goodbye.
