278 The Secret of World War Two (2/2)

”I don't think so.”

”This is the problem.” Lin Lin pointed at the briefcase, ”The Klein particle transmitting in the fourth dimension would not have its signal changed because of the shift in three-dimensional coordinates. Or rather, it doesn't possess the physics properties such as energy or speed. It is only a hypothetical wave. It would receive a certain signal at a certain time, it is that simple.”

”Could it be received in any corner of the universe?” Jiang Chen was stunned.

”It can. So it is also referred to as communication particle in the intergalactic era. Since with electromagnetic wave, there is a delay of one second from earth to the moon, it would take over half a year to get to the Oort cloud at the edge of the solar system. Without the restriction of the third dimension, as long as it is broadcasted to the same time coordinate, the signal can be received in any corner of the universe. And even before the war, it was a project at the frontier of science. However, even for me now, I could only do this with two crystals with the same origin and communicate in the form of resonance,” Lin Lin said.

Because it was too magical. Compared to the Klein particles, the electromagnetic wave was more similar to sending a message on a pigeon.

”Then why would the signal from this thing decrease with increasing distance?” Jiang Chen asked, confused.

”This is why it is a half-finished product. Or rather, the person producing it never understood the principle behind it. The person probably only followed a diagram to create something similar.”

Lin Lin sighed, paused, and provided a rather simple analogy.

”For example, I have a phone, and I passed the phone back to the stone age and told him he can use this to call me. He never saw this before as they always used messenger pigeons to communicate and have no concept of communicating with a phone. So he used a dumb method, that is carving the letters onto the phone, and then relaying the message to me by tieing the phone to the messenger pigeon.”

Jiang Chen had a funny expression on his face, but he suddenly realized something.

”Could it be the message from the future sent the diagram to create the fourth-dimensional messenger back. Someone used the diagram to create the communication device but didn't how to ”call,” so the person used electromagnetic waves to send it and broadcasted Klein particle waves into the third dimension.

”That's a possibility.” Lin Lin didn't disagree with Jiang Chen's perspective. ”Let's hypothetically say the video you showed me last time was a mature phase of the Klein particle communication technology. The friendly hello was the greeting from the people in the ”future” or the ”primal.” At the same time of the greeting, it also brought you advanced technology. Along with the message would include the manufacturing method to create a Klein particle communication device.”

”Those incredible technologies?”

Jiang Chen recollected the incredible technology the Third Reich brought out during the Second World war as Jiang Chen had a strange expression on his face.

”That's right.” Lin Lin nodded. ”Do you remember what I told you last night? Some people can interpret these signals in the form of dream with this special wave effect. But, these special brains could only passively receive information. Just like a deaf person on the phone, you would not know if the other side is listening to you speak. To be able to confirm if the people in the past received the information or not, what you need to do is simple, it is to send the method of communication as well as coordinate along with it.”

”Then did this ”help” ever get heard by the people in the future?”

”Obviously not.” Lin Lin sighed, she closed the fourth-dimensional messenger. ”That person clearly overestimated the ”primitive” ability to understand. Even the strongest pigeon would not fly through the distance of time.”

Until its collapse, the Third Reich didn't manage to communicate with the voice in the future.

Jiang Chen didn't say anything as he quietly looked at the briefcase thinking about something else.

”Can I open this briefcase?” Lin Lin pointed at it.

”Of course, but I didn't manage to find the key to open it, so I am not sure if there is a trap mine inside.” Jiang Chen shrugged.

”That is simple.” Lin Lin had a prideful smile emerge on her face as she put the briefcase on her experiment table. ”I am not that dumb to be tricked by the primal's trap.”

There was no mine inside, it was easily opened.

A black metallic ball slightly bigger than a baseball along with a notebook was inside.

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

There was no opening on it as it didn't look like it could be opened. Jiang Chen managed to find a neat line of small letters on it.

”German?”

Jiang Chen was troubled as he knew only one foreign language.

”Use this.” Lin Lin threw a translucent carbon graphene card into Jiang Chen's hand, ”As long as the writing is not too messy, this thing can easily translate it into any common language.”

”Woah, this is amazing!” Jiang Chen was stunned.

Looking at Jiang Chen's shocked expression, a glimpse of proudness appeared on the tip of Lin Lin's lips.

She enjoyed viewing his ”primal” reaction. It made her feel like a God, any ”offering” would gain the worship of her ”believers.”

However, she didn't make it as it was the scavenger team who managed to pick it up. She only fixed it up.

Usually, things like this would be thrown into the extraction tank and recycled for useful material, since the apocalypse didn't require translation. But the reason why she fixed it was due to Yao Yao's request since as a digitalized human, Lin Lin herself didn't need it.

”The Golden Apple?” After attaching the translation card to the line of small writing, Jiang Chen read out loud.

It was a pure black metallic ball, why would it be called the Golden Apple?

”Let me look at it, you can go read that notebook.” Lin Lin took the golden apple from Jiang Chen's hand as she couldn't wait to work on an experimental apparatus.

Jiang Chen understood why she couldn't wait another second.

This feeling was as if a cell phone was found in a grave dated back to the Han dynasty.

Jiang Chen picked up the notebook and opened the cover.

A diary.

Perhaps the secret is hidden inside his diary.
