"Uranium? Where did you get it?"
Lin Ling glanced at the bucket Jiang Chen threw in the corner with disgust, as if looking at something dirty.
In the process of "arm wrestling" with the mutated octopus, the driving system of the mechanical exoskeleton was slightly damaged because Jiang Chen started to go crazy. In order to prevent the chain from suddenly falling off when returning to the sea, Jiang Chen returned to the apocalyptic side with this suitcase after getting rid of the mutated octopus.
After throwing the equipment to Jiang Lin for repair, Jiang Chen then found Lin Ling.
"Although our technology over there is a bit backward, we still have things like atomic bombs."
"Really? The speed of clicking the technology tree is surprisingly fast. Has it already entered the atomic age?" Lin Ling flipped up her long silver hair and sat on the office chair. "Then what? You get this thing?" What is my lab doing?"
"I would like to ask, how many nuclear bombs can be made with these more than 500 kilograms of uranium?"
Hearing Jiang Chen's words, Lin Ling was slightly stunned. She held her chin and thought for a moment before answering.
"Nuclear bomb? It depends on what type. Uranium-235 can only be used to make the most primitive fission bomb. In addition, the abundance of uranium-235 element must be considered. Assume that this batch of materials can be purified into 100 kilograms of enriched material. Uranium. With pre-war technology, almost 12 nuclear bombs with the equivalent of 10,000 tons of TNT could be made. If it were the technical level at the beginning of the atomic age, almost 1 kilogram of 50 kilograms of enriched uranium could complete the chain reaction, and about 2 pieces."
"That's right." Jiang Chen nodded thoughtfully.
"Are you going to let me help you build a nuclear bomb?"
"If you have this plan, can you do it?"
All the tactical nuclear bombs collected from the Sixth Block have been used on -1 ballistic missiles deployed in every corner of Qingpu. In a wasteland where resources are scarce, these remaining nuclear weapons are used less and less.
"One hundred puddings, lemon flavored!" Lin Ling said unceremoniously.
"Deal." Jiang Chen said happily.
It's really cheap.
Surprisingly, after hearing Jiang Chen's promise, Lin Ling did not show her usual expression of joy. Instead, she gave Jiang Chen a meaningful look.
"I have to say one more thing, this thing is poison."
Hearing this, Jiang Chen was stunned. Silence fell immediately.
After a moment, he spoke.
"I will use it with caution."
"Well, that's good." Lin Ling nodded, with a smile on her smooth face like a porcelain doll. "If possible, I'd like to continue eating the pudding you brought."
The unnatural light passed over the window eaves, and for some reason, it actually made that beautiful smile feel a bit sad.
Speaking of which, the world was destroyed by nuclear weapons.
Subtly looking away. Jiang Chen took out the black suitcase from the storage space and changed the previous topic.
"Can you help me take a look at this?"
"What is this thing?" Lin Ling looked at the suitcase placed on the table by Jiang Chen, with an expression of interest on her face.
"I found it on a U-boat... The Axis submarine in World War II is a rather special antique."
"Oh? World War II? That's really a distant story." Lin Ling took the suitcase, her electronic eyes shrank slightly, and she carefully inspected its surface texture, and at the same time asked casually, "What's so special about it? "
"It excites Crane particle waves."
"This is impossible." Lin Ling categorically rejected it and turned on the four-dimensional communication equipment on the table. "People in the atomic age can't even do dimensional observation. How could they be aware of the existence of Crane particles—"
However, just halfway through speaking, Lin Ling's voice froze.
There are no sounds, just four letters.
[Help]
"This, this is impossible... Wait, this is just a semi-finished product. No, even a semi-finished product. It is absolutely impossible to do it with the technological level of the atomic age." Lin Ling's eyes widened in disbelief. said.
Seeing Lin Ling's surprised look, a trace of confusion appeared on Jiang Chen's face.
"Half-finished product? Can you explain?"
Hearing Jiang Chen's inquiry, Lin Ling glanced at Jiang Chen.
"Think about it carefully. When you use a fourth-dimensional transmitter to communicate with me, does the signal strength change as your position changes?"
"It seems not."
"That's the problem." Lin Ling tapped her finger on the suitcase, "The signal strength of the Crane particle wave propagating in the four dimensions will not attenuate as the three-dimensional coordinates change. Rather, It does not have physical properties such as energy and speed at all, it is just a conceptual wave. You can receive a specific signal at a specific point in time. It's that simple."
"Can I receive it anywhere in the universe?" Jiang Chen couldn't help but feel moved.
"Yes, so it is also called the communication particle in the interstellar era. After all, if electromagnetic waves are used for communication, there will be a delay of 1 second from the earth to the moon, and it will take a lot of time to reach the boundary of the solar system, the Oort cloud. Half a year. It is not limited by three dimensions at all. As long as the coordinates of the same time are broadcast, the signal can be received in any corner of the universe. But even before the war, this kind of thing was considered 'cutting-edge science', even for me, It can only transmit information in a resonance manner between two homologous sub-crystals," Lin Ling said.
It's really amazing. Compared with electromagnetic waves, electromagnetic waves are more like flying pigeons delivering messages.
"Then why does the signal emitted by this thing attenuate with distance?" Jiang Chen asked confused.
"So it is a semi-finished product. In other words, the maker did not understand the principle of this thing at all. He just built something similar based on a drawing or something like a gourd."
Lin Ling sighed, paused, and gave a fairly common example.
"It's like I was holding a mobile phone in my hand. I handed it into the hands of primitive people and told him that he could use this thing to make calls to me. But he had never seen this thing before. He had always used it to fly. He did not know what the concept of making a phone call was. So he used a stupid method, which was to use a knife to carve words on the phone case, and then tied the phone to the pigeon's foot and mailed it to me. ."
Jiang Chen had a look of laughter on his face, but then, there was a hint of surprise on his face.
"Could it be a message from the future that sent the drawings for making four-dimensional communication equipment to the past? Someone copied the drawings and built the communication equipment. But he didn't know how to make a phone call, so he used a transmitter In the form of electromagnetic waves, Crane particle wave signals are broadcast in three dimensions.”
"It is possible." Lin Ling did not deny Jiang Chen's point of view, "We assume that the image you showed me last time is the mature Crane particle communication technology. That hello, which symbolizes friendship, is It's the greetings from the 'future people' to the 'primitive people' over there. While saying hello, they also brought you some cutting-edge technologies. Among those technologies, they include the manufacturing process of Crane's particle communication equipment."
"Those black technologies?"
Thinking of the black technologies that the Third Reich came up with during World War II, Jiang Chen couldn't help but have a strange expression on his face.
"That's right." Lin Ling nodded. "Remember what I told you last time? Under the strong influence of this special wave, some people will translate these signals into video information in the form of dreams. However, what these specially constructed brains can do It's just passively receiving messages. Just like talking to a mute on the phone, you have no way of knowing whether the person on the other end is listening to you. If you want to confirm whether people in the past have received those messages, what you need to do is also very simple, That is to send them the method of 'speaking' along with the coordinates."
"Then this line of 'Help' has been heard by people in the future?"
"Obviously not." Lin Ling sighed and reached out to turn off the fourth-dimensional communication device. "That person obviously overestimated the understanding ability of primitive people. No matter how strong the homing pigeon is, it cannot fly across the distance of time."
It seems that until its demise, the Third Reich failed to get in touch with the voice from the future.
Jiang Chen didn't speak, he just looked at the suitcase quietly, thinking about something.
"Can I open this box?" Lin Ling pointed to the suitcase.
"Of course, but I didn't find the key to open the box, and I'm not sure if there are booby traps in the box." Jiang Chen shrugged.
"This is easy to handle." Lin Ling raised a proud smile and placed the box on her experimental equipment. "I'm not stupid enough to be plotted by the primitive man's trap."
However, the box was not booby-trapped and was opened easily.
A black metal ball slightly larger than a baseball. There is also a notebook.
"This is..." Jiang Chen picked up the black ball and carefully observed its surface.
There are no cracks on the surface, so it doesn't look like it can be opened. In an inconspicuous place, Jiang Chen found a neat line of small characters.
"German?"
Now Jiang Chen was in trouble. He only speaks one foreign language.
"Use this." Lin Ling threw a translucent graphene card into Jiang Chen's hand. "As long as the handwriting is not particularly sloppy, it can be easily translated into any commonly used language."
"Damn it, this is so shocking!" Jiang Chen said in shock.
Seeing Jiang Chen's shocked look, Lin Ling's lips raised a hint of pride.
She just admired his "country bumpkin" behavior. This made her feel like she was a god, and she could be worshiped by "believers" just by "giving alms" at will.
Although this thing is not considered to be made by her. It was just that the scavenging team found it and she repaired it.
Usually this kind of thing will be thrown into the refining furnace to recover useful materials. After all, there is no need for translation in the end of the world. The reason why this thing was repaired was mainly due to Yao Yao's request. After all, as a cyborg, Lin Ling herself did not need such a thing.
"Golden Apple?" Jiang Chen pasted the translation card on the small line of characters and read it out in a low voice.
It's obviously a pure black metal ball, but it's called a golden apple
"Give me that to study. Just look at the notebook." Lin Ling took the golden apple from Jiang Chen's hand and eagerly walked towards an experimental instrument.
It's not that Jiang Chen couldn't understand her impatient look.
This feeling is roughly equivalent to discovering a Big Brother movie in an ancient tomb of the Han Dynasty.
Jiang Chen picked up the note and opened its title page.
This is a diary.
Perhaps, the secret is hidden in this diary. (.)
