For Ding Chen, where did it come from was also a question that puzzled him, because when he woke up from the desert, no one told him where it was, because the satellite positioning system failed, and the positioning device on the escape capsule also lost its effect, he could only judge according to the astrological appearance, he should be near 95 degrees east longitude and 60 degrees north latitude, as for how much was nearby, only God knows. Pen? Interesting? Pavilion wWw. ｂiquge。 info He just instinctively felt that he should be in Xinjiang.

Later, when he met Tifa, he was shocked to find that the terrain of the world had changed, and the land area had shrunk a lot, and if this factor was to be considered, then the place where the escape pod landed could also be the Inner Mongolia grassland.

It's a sad story to not know where you're coming from.

Seeing the hesitant look on Ding Chen's face, Zhong Di nodded very calmly, and took the initiative to change the question, "Why did you come to the Capital District?" ”

"I want to know what's going on in the world?" This is a question that can be answered, so Ding Chen immediately said: "Why did it become the way it is now." ”

"Intellectual curiosity." Zhong Di said: "You are very curious. She picked up a paper report in front of her, flipped through it, and said, "Leng Yue reported that you used to be a waste picker?" ”

Ding Chen nodded, he finally sorted out his clothes, and stood in front of Zhong Di with his legs slightly apart and his hands behind his back, "I wandered in the wild for three years before I found a large gathering area. ”

"That can only mean that you are unlucky." Zhong Di was very satisfied with Ding Chen's military posture, and she said, "Either you perfectly avoided the gathering area on the way, or the place where you were born was too far north. She looked at Ding Chen, "For some historical reasons, there is no gathering area in the north. ”

"I understand." Ding Chen said: "Can you tell me the answer you want to know?" ”

Zhong Di pondered for a moment, shook his head and said, "I'm sorry, I'm not interested in the past. However, if you have the chance, I suggest you go to the National Archives, where there will be more detailed information. ”

Speaking of this, her face involuntarily showed a look of nostalgia, "I have a friend who is very familiar with it, but it's a pity that she is now in District 11, otherwise I can take you there." ”

She smiled and gestured to the couch beside her, "Of course, in return for your willingness to be here, I'm willing to tell you something I know." ”

Ding Chen couldn't ask Zhong Di where to start, so when he sat on the sofa, he was ready to start listening to Pangu Kaitian, but he didn't expect Zhong Di to be worthy of the identity of the commander, and he started very neatly and directly before the great changes in the world.

"At that time, our country was one of the two most powerful countries in the world." Zhong Di said: "Or one of them should be removed." She waved her hand, "You've seen what the Capital District looks like, but at that time, such cities were all over the country, and the real capital was much bigger than here. Speaking of this, her eyes brightened, "I have read some materials at that time, and you can't imagine how powerful the country was at that time. ”

"The world was chaotic at that time, and the western part of Asia and Europe were at war for many reasons. The bad thing is that the side with strong force is always tied down for various reasons, and there is no way to end the war quickly, so it can only let itself lose blood slowly. At that time, there was something called nuclear weapons that threatened the whole world. ”

Zhong Di stopped and looked up at Ding Chen, "You know what a nuclear weapon is, right?" "A weapon of mass destruction," she said. ”

Ding Chen nodded and motioned for her to continue. Zhong Di looked at him inquiringly, shook his head and said, "I don't think you understand what it is, in fact, I'm afraid you don't know anything about power." "But that's okay, just remember the background," she said. ”

"Later, a scientist in our country found a way to neutralize nuclear fission, and the main principle is to use an artificial particle to absorb scattered neutrons and end the fission reaction. To be honest, it's a complicated process, and there's only so much I can understand. ”

"The results of this research won him the Nobel Prize that year, but he was quickly suspected of falsification because he did not publish detailed data."

"At that time, the Chinese government prevented the scientist from announcing the specific implementation method in the name of national security, but there was a lot of pressure from the international community."

Speaking of this, Zhong Di smiled, "You guess you won't understand why there is pressure. ”

"Nuclear Balance." Ding Chen said: "If everyone can destroy each other, then they will not be destroyed, so you can't let yourself have a way to survive alone." "I can even guess who first questioned it," he said. ”

Zhong Di looked at him and said after a while, "It looks like you have a good teacher." ”

"In fact, I've had a lot of good teachers." Ding Chen said.

Zhong Di looked at him deeply, and then said, "But you don't know what is going on in this world. So I'm guessing there's a break in the data lineage where you used to be. "It's not surprising," she said slowly, "if this hadn't happened, the world wouldn't be like this now." The way we store information is still too fragile. ”

"In the end, the whole world won." "The means of protecting peace were announced, and from then on, nuclear weapons were no longer a sword hanging over the head of mankind, and then the Europeans dropped such a big bomb on the Eurasian border," Zhong Di said. ”

She laughed, "Ironic, isn't it?" ”

"I can understand that even if there is a method, it will take strong industrial and scientific research capabilities to make it." Ding Chen said: "So the Europeans took advantage of this, and they were not afraid that the enemy would also throw nuclear bombs on their heads." But aren't they afraid of nuclear contamination? ”

Zhong Di looked at him scrutinically, "Looks like you do know about nuclear weapons." "You also know about nuclear contamination," she said. But they were not afraid, because as an incidental technology, our scientist had discovered an inexpensive way to eliminate nuclear contamination at the cost of reducing the particle activity of various local nuclear elements for a considerable period of time. ”

She looked at Ding Chen and was very satisfied to find that Ding Chen was beginning to be confused. He further explained: "This means that after using this method to eliminate nuclear pollution, it is impossible to build a nuclear power plant in the local area, and even medical equipment will not be used." ”

"So nuclear states can use nuclear weapons with impunity?" Ding Chen said in surprise: "The strategic deterrence weapon has become a tactical strike weapon? ”

"That's right." Zhong Di nodded, feeling that Ding Chen not only has a lot of knowledge, but also has a very smart brain, and people who have these two points at the same time are rare even in the capital region.

"Actually, the term 'nuclear state' is not accurate." "The way to eliminate nuclear contamination is cheap, but it still requires a lot of industrial manufacturing capacity," she said. She waved her hand and said, "Even if you make small steel balls, it will be very troublesome if there are too many of them, so in fact, there are not many countries that have the ability to destroy and recover at the same time." ”

She looked at Ding Chen and said: "The Europeans preemptively used nuclear weapons, not because they were arrogant enough, but because they couldn't afford to fight, years of war have caused Europe's population to plummet, the economy collapsed, internal turmoil in various countries, and the relationship between the allies has become extremely fragile, if it weren't for the common threat from Asia, it would have collapsed long ago." So when they found out that there was a way to end the war quickly, they couldn't wait to use it. ”

"Then, the world war broke out."
