"Uranium? Where did you get it from?"

Lin Ling glanced disgustedly at the bucket Jiang Chen threw in the corner, as if he was looking at something dirty.

During the process of the "wrench wrist" with that mutant octopus, the drive system of the mechanical exoskeleton was slightly damaged by Jiang Chen's madness. In order to prevent the chain from suddenly falling when returning to the sea, after solving the mutant octopus, Jiang Chen returned to the end of the world with this suitcase.

After throwing the equipment to Jiang Lin for repair, Jiang Chen then found Lin Ling.

"Although our technology is a bit behind, there are still things like atomic bombs."

"Really? The speed of the technology tree is unexpectedly fast. Has it entered the atomic age." Lin Ling lifted her long silver hair and sat on the office chair. "Then? What do you do? Why did I get something in my laboratory? "

"I would like to ask, how many nuclear bombs can be made with these more than 500 kilograms of uranium?"

After hearing Jiang Chen's words, Lin Ling froze a little, holding her chin and thinking for a moment, then replied.

"Nuclear bomb? That depends on the type. Only uranium 235 can be used to make the most primitive fission bomb. In addition, the abundance of uranium 235 element must also be considered, assuming that this batch of materials can be purified to a Hundred kilograms of enriched uranium. With pre-war technical means, nearly ten tons of TNT-equivalent nuclear bombs can be built. If it is the level of technology in the early atomic age, about 50 kilograms of enriched uranium can complete 1 kilogram of chain reaction, probably Create 2 pieces. "

"Such." Jiang Chen nodded thoughtfully.

"Are you going to let me build a nuclear bomb for you?"

"Is this planned, can it be done?"

The tactical nuclear bombs recovered from the 6th block have been used in W-1 ballistic missiles deployed in various corners of Qingpu. On the wasteland where resources are scarce, these residual nuclear weapons are used less and less.

"One hundred puddings, lemon flavor!" Lin Ling said bluntly.

"The deal." Jiang Chen said happily.

It's really cheap.

I was surprised that after hearing Jiang Chen's promise, Lin Ling did not show a joyful expression as usual, but instead gave Jiang Chen a meaningful look.

"I have to talk more, this thing is poison."

After hearing this, Jiang Chen was stunned, and then fell into silence.

After a moment, he said.

"I will use it carefully."

"Well, that's good." Lin Ling nodded, a smile on the porcelain doll's smooth face, "If I can, I want to continue eating the pudding you brought."

Unnatural light crossed the window eaves, somehow, it made the beautiful smile feel a bit sad.

Speaking of this, this world is destroyed by nuclear weapons.

Subtly away from his eyes, Jiang Chen took out the black suitcase from the storage space and diverged from the previous topic.

"Can you help me see this thing?"

"This thing is?" Looking at the suitcase that Jiang Chen put on the table, Lin Ling's face showed an expression of interest.

"I found it on a U-shaped submarine ... In the Second World War, the submarine of the Axis Kingdom was considered a special antique."

"Oh? World War II? That's really a distant story," Lin Ling took the suitcase, the electronic eye slightly shrunk, carefully inspected its surface texture, and asked casually, "Special Where is it? "

"It can excite the Klein particle wave."

"This is impossible," Lin Ling categorically rejected, and opened the four-dimensional communication device on the table. "The people in the atomic age can't even observe the dimensions, how can they realize the existence of Klein particles- — ”

But halfway through this, Lin Ling's voice froze.

There is no sound, only four letters.

【Help】

"This, this is impossible ... wait, this is only a semi-finished product. No, even if it is a semi-finished product, it is absolutely impossible to achieve it with the technological level of the atomic age." Lin Ling's eyes widened, Said incredulously.

Looking at Lin Ling's startling look, Jiang Chen's face appeared a little confused.

"Semi-finished products? Can you explain?"

Hearing Jiang Chen's inquiry, Lin Ling glanced at Jiang Chen.

"If you think about it carefully, when you use a four-dimensional transmitter to communicate with me, will the signal strength change with the change of position?"

"It doesn't seem to be."

"The problem is here." Lin Ling's finger clicked on the suitcase. "The Klein particle wave propagating in the four dimensions, the signal strength will not be attenuated with the change of the three-dimensional coordinates. It ’s better to say that it does n’t have the physical properties of energy and speed at all. It is just a wave of a concept. It is so simple to receive a specific signal at a specific time. ”

"Can it be received anywhere in the universe?" Jiang Chen couldn't help but move.

"Yes, so it is also called the interstellar communication particle. After all, if it uses electromagnetic waves to communicate, there must be a delay of 1 second from the earth to the moon, and even to the Orte cloud at the boundary of the solar system. It takes more than half a year. It is not limited by the three-dimensionality at all. As long as the simultaneous coordinates are broadcast, the signal can be received in any corner of the universe. But even before the war, this kind of thing is regarded as "frontier science". I am the only one who can only pass information between two homologous subcrystals in a resonant way. "Lin Ling said.

It is really amazing. Compared with electromagnetic waves, electromagnetic waves are more like flying pigeons.

"Then why the signal from this gadget attenuates with distance?" Jiang Chen asked in confusion.

"So it is a semi-finished product. Or, the creator did not understand the principle of this thing at all, just according to a drawing or something, and made a similar thing out of the calabash."

Lin Ling sighed and paused, giving a fairly popular example.

“It ’s like I ’m holding a cell phone in my hand, and I handed him over to the primitive man and told him to use this thing to call me. But he ’s never seen it before, it ’s always He communicated information in the way of flying pigeons, and he did n’t know the concept of making a call. So he used a stupid method, that is, he used a knife to engrave words on the phone case, and then tied the phone to the feet of the pigeon Mail me. "

Jiang Chen's expression on his face couldn't help but, immediately, a sudden expression appeared on his face.

"Will it be a message from the future, sending the drawings of the four-dimensional communication equipment to the past. Someone made the communication equipment according to the gourd, but did not know how to 'call', so Then, by emitting electromagnetic waves, the signal of the Klein particle wave is broadcast in three dimensions. "

“There is such a possibility.” Lin Ling did not deny Jiang Chendi ’s point of view. “We assume that the video you showed me last time is the mature Klein particle communication technology. The sentence symbolizes friendly Hello is the "Future Man" 's hello to the "Primeman" on your side. At the same time, it brings you some cutting-edge technology. Among those technologies, including the manufacture of Klein particle communication equipment Craft. "

"Those black technologies?"

Reminiscent of the black technology that the Third Reich brought out during World War II, Jiang Chen couldn't help but have a strange expression on his face.

"Yes." Lin Ling nodded. "Do you remember what I told you last time? Under the strong effect of this special wave, some people will translate these signals into video in the form of dreams. Information. However, all these specially constructed brains can only passively receive messages. Like calling a dumb phone, you ca n’t know whether the other side is listening to you. If you want to confirm whether people in the past have received it When it comes to the information, what you need to do is also very simple, that is, send them the "speaking" method together with the coordinates. "

"Then this line of‘ Help ', was it heard by future people? "

"Obviously not." Lin Ling sighed and reached out to turn off the four-dimensional communication device. "That person obviously overestimated the primitive man's ability to understand. No matter how strong the pigeons are, they can't jump 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, just quietly looked at the suitcase, thinking about something.

"Can I open this box?" Lin Ling pointed to the suitcase.

"Of course, but I didn't find the key to unpack the box, and I'm not sure if there was a bait mine in the box." Jiang Chen shrugged.

"This is easy to handle," Lin Ling raised a proud smile on the corner of her mouth, and placed the box on her experimental equipment. "I'm not stupid enough to be calculated by the primitive trap."

However, the box was not equipped with lures, and was easily opened.

A black metal ball slightly larger than baseball, and a note.

"This is ..." Jiang Chen picked up the black ball and carefully observed its surface.

There are no cracks on the surface, it looks like it can be opened. In a humble place, Jiang Chen found a neat line of small characters.

"German?"

Xia Jiangchen is in trouble, he can only speak a foreign language.

"Use this." Lin Ling threw a translucent graphene card into Jiang Chen ’s hand. "As long as the handwriting is not particularly scribbled, it can be easily translated into any common language."

"Lying trough, it just burst!" Jiang Chen shocked.

Looking at Jiang Chen's shocked appearance, Lin Ling's mouth lifted with pride.

She just appreciates his performance of "soil buns". This made her feel like a god, and she could be worshipped by "believers" by simply giving alms.

Although she ca n’t do it, it ’s just that the scavengers picked up the trash, and she repaired it.

Usually this kind of stuff will be thrown into the refining furnace to recycle useful materials. After all, there is no need to translate in the last days. The reason why this thing is repaired is mainly due to Yao Yao. After all, Lin Ling, who is a cyborg, does not need this kind of thing.

"Golden Apple?" Paste the translation card on the line of small characters, and Jiang Chen whispered it out.

It is obviously a pure black metal ball, but it is called a golden apple?

"Give me the research and study, you just need to read the note." Lin Ling took the golden apple from Jiang Chen and couldn't wait to walk to an experimental instrument.

Jiang Chendang, who can't wait for her, is not incomprehensible.

This feeling is probably equivalent to finding a big brother in the ancient tomb of the Han Dynasty.

Jiang Chen picked up the note and opened its title page.

This is a diary.

Probably, the secret is hidden in this diary. (To be continued.)
