"Uranium? Where did you get it? "
Lin Lin glanced at the bucket Jiang Chen threw in the corner with disdain as if she was looking at something dirty.
In the process of "arm wrestling" with the mutated octopus, the kinetic skeleton's drive system was slightly damaged because Jiang Chen activated fury. To prevent any accidents when he returned to the surface, after taking care of the mutated octopus, Jiang Chen brought the suitcase back to the apocalypse.
After he gave the equipment to Jiang Lin to repair, Jiang Chen then went to find Lin Lin.
"Although our technology is a bit behind, we still have things like atomic bombs."
"Is that so? The speed of the technology tree is surprisingly fast. Have we already entered the atomic era? "Lin Lin flipped her silver hair and sat on the office chair." And then? Why did you bring this thing to my lab? "
"I want to ask, with these 500 kilograms of uranium, how many nuclear bombs can we make?"
When Lin Lin heard Jiang Chen's words, she was slightly taken aback. She rubbed her chin and thought for a moment before answering.
"Nuclear bombs? That depends on the type. If it's just uranium 235, it can only be used to make the most primitive fission bomb. Also, we have to consider the abundance of uranium 235. Let's say this batch of materials can purify 100 kilograms of enriched uranium. With the technology before the war, 12 nuclear bombs with 10,000 tons of TNT can be made. If it's the technological level of the early atomic era, 50 kilograms of enriched uranium can have 1 kilogram complete the chain reaction, so we can make two bombs. "
"I see." Jiang Chen nodded thoughtfully.
"Are you planning to ask me to help you build a nuclear bomb?"
"I plan to. Can you do it?"
The tactical nuclear bombs collected from the Sixth Street were all used on the W-1 ballistic missiles deployed in every corner of Qingpu. On the resource-deficient wasteland, the remaining nuclear weapons would be used less and less.
"One hundred puddings, lemon flavored!" Lin Lin said without hesitation.
"Deal," Jiang Chen said cheerfully.
[That's cheap.]
Surprisingly, after hearing Jiang Chen's promise, Lin Lin didn't show her usual excited expression. Instead, she looked at Jiang Chen with a meaningful look.
"I have to say something. This thing is poison."
Hearing this, Jiang Chen paused for a moment and then fell into silence.
After a moment, he said.
"I will use it wisely."
"En, that's good." Lin Lin nodded, and a smile appeared on her doll-like face. "If possible, I want to continue eating the pudding you brought."
The unnatural light shone through the window. For some reason, that beautiful smile was tainted with a sense of poignant beauty.
Speaking of which, the world was destroyed by nuclear weapons.
Jiang Chen subtly looked away, took out the black suitcase from the storage dimension, and changed the topic.
"Can you help me look at this thing?"
"What is this?" Lin Lin looked at the suitcase on the table with interest.
"I found it on a U-boat … It was an Axis submarine from World War II. It's a special antique."
"Oh? The Second World War? That's a long story. " Lin Lin took the suitcase. Her bionic eyes narrowed as she carefully examined the patterns on the surface. At the same time, she asked casually, "What's special about it?"
"It can stimulate Klein particle waves."
"That's impossible." Lin Lin vehemently denied and turned on the fourth-dimensional communication device on the table. "People in the atomic era can't even observe dimensions, how could they realize the existence of Klein particles —"
But halfway through, Lin Lin's voice froze.
No sound, only four letters.
"This, this is impossible … Wait, this is only a semi-finished product. No, even if it's a semi-finished product, it's impossible with the technological level of the atomic era. "Lin Lin's eyes widened as she said in disbelief.
Looking at Lin Lin's shocked expression, Jiang Chen was confused.
"Semi-Finished product? Can you explain? "
When Lin Lin heard Jiang Chen's question, she glanced at Jiang Chen.
"Think about it carefully. When you used the fourth-dimensional messenger to communicate with me, would the strength of the signal change according to the location?"
"I don't think so."
"That's the problem." Lin Lin's finger tapped on the briefcase. "The Klein particle waves propagating in the fourth dimension, the signal strength will not weaken with the change of three-dimensional coordinates. Or rather, it doesn't possess the physical attributes of energy or speed. It's just a wave that exists in a concept. It can receive a specific signal at a specific time, it's that simple. "
"It can be received at any corner of the universe?" Jiang Chen was shocked.
"That's right, so it's also known as the communication particle of the interstellar era. Since if it's electromagnetic wave communication, there would be a delay of one second from the Earth to the Moon, and it would take more than half a year to reach the Oort Cloud at the edge of the solar system. It's not limited by the third dimension. As long as it's broadcast at the same time, any corner of the universe can receive the signal. But even before the war, this was considered "cutting-edge science." Even for me, I could only transmit information through resonance between two crystals of the same origin, "Lin Lin said.
It was amazing. Compared to electromagnetic waves, electromagnetic waves were more like messenger pigeons.
"Then why does the signal from this thing weaken with distance?" Jiang Chen was confused.
"So it's a half-finished product. In other words, the creator didn't understand the principle behind this thing at all. He just followed a certain blueprint and created something similar. "
Lin Lin let out a sigh, paused, and gave a rather common example.
"It's like I had a phone in my hand. I handed it to a primitive man and told him he could use this thing to call me. But he had never seen this thing before. He had always used pigeons to communicate and didn't know the concept of making a phone call. So he used a stupid method, which was to use a knife to carve words on the phone, and then tie the phone to the pigeon's leg and mail it to me. "
Jiang Chen couldn't help but laugh, but then, a look of realization appeared on his face.
"Could it be a message from the future that sent the blueprint of the fourth dimension communication device to the past? Someone copied the blueprint and created a communication device, but didn't know how to make a phone call. So he used electromagnetic waves to broadcast the Klein particle wave signal in the third dimension. "
"That's possible." Lin Lin didn't deny Jiang Chen's point. "Let's assume that the video you showed me last time was the mature Klein particle communication technology. The 'hello' that symbolized friendliness was the greeting from the 'future' to the 'primitive man' on your side. While greeting, it also brought you some cutting-edge technology. Among those technologies, it included the manufacturing process of the Klein particle communication device. "
"That black technology?"
Jiang Chen thought about the black technology that the Third Reich brought out in World War II as an odd expression appeared on his face.
"That's right." Lin Lin nodded. "Do you remember what I told you last time? Some people, under the strong effect of this special wave, will translate these signals into video messages in the form of dreams. However, these specially constructed brains could only passively receive information. Just like talking to a mute person, you can't know if the person on the other side is listening to you. If you want to confirm if the people in the past received the information, what you need to do is simple – send the way to 'speak' and the coordinates to them. "
"Did the people in the future hear this line of 'help'?"
"Obviously not." Lin Lin let out a sigh and turned off the fourth dimension communication device. "That person clearly overestimated the comprehension ability of the primitive man. Even the strongest pigeon can't fly the distance of time. "
It seemed that even until its demise, the Third Reich couldn't contact the voice from the future.
Jiang Chen didn't say anything as he quietly stared at the suitcase, thinking about something.
"Can I open this suitcase?" Lin Lin pointed at the suitcase.
"Of course, but I didn't find the key to open the suitcase, and I'm not sure if there's a booby trap inside." Jiang Chen shrugged.
"That's easy." A proud smile appeared on Lin Lin's face as she put the suitcase on her lab equipment. "I'm not stupid enough to fall for the trap of the primitive man."
But the suitcase didn't have a booby trap, so it was easily opened.
A black metal ball slightly larger than a baseball and a notebook.
"This is …" Jiang Chen picked up the black ball and carefully observed its surface.
There were no cracks on the surface, so it didn't look like it could be opened. In an inconspicuous place, Jiang Chen found a neat line of words.
"German?"
Jiang Chen was in a difficult position as he only knew one foreign language.
"Use this." Lin Lin threw a translucent graphene card into Jiang Chen's hand. "As long as the handwriting isn't too messy, it can be easily translated into any common language."
"Fu * k, this is insane!" Jiang Chen was shocked.
Looking at Jiang Chen's shocked expression, Lin Lin's mouth curved up with pride.
She admired his "bumpkin" performance. It made her feel like she was a god who could receive the worship of her "believers" just by "giving".
Although this thing wasn't made by her, it was just something picked up by the scavenger team and she repaired it.
Usually, this kind of thing would be thrown into the furnace to recycle the useful material since the apocalypse didn't need translation. The reason why she repaired this thing was mainly because of Yaoyao's request. Since Lin Lin, as a digitalized human, didn't need this kind of thing.
"Golden Apple?" Jiang Chen put the translation card on the line of words and read it out in a small voice.
It was a pure black metal ball, but it was called a Golden Apple?
"Let me study that. You can go read the notebook." Lin Lin took the Golden Apple from Jiang Chen's hand and eagerly walked to the lab equipment.
Jiang Chen could understand her eagerness.
This feeling was similar to finding a cellphone in an ancient tomb of the Han Dynasty.
Jiang Chen picked up the notebook and flipped to the title page.
It was a diary.
Perhaps, the secret was hidden in this diary.
