"Yes, I've never mentioned this secret before, and no one has thought of it. General, you should remember that a pair of entangled particles are connected in the fourth dimension. Our four-dimensional communication uses concentrated energy to open and expand a channel between a pair of entangled particles in the fourth dimension, and uses this channel to transmit information, achieving a fast and stable effect."
"Of course I remember that, but what does it have to do with assassination?"
"Of course there is. If I had a pair of entangled particles in advance, one in my hand and the other floating into your brain, and then I suddenly applied energy to the particle in my hand to open the channel, and then used the channel to infuse the antimatter particle into your brain, General, the result is self-evident."
"I see!"
"Yes, that's why all the civilizations we've seen, whether it's the Wind Star Civilization, the Xuan Star Civilization, or even ourselves, have built numerous electromagnetic shielding systems and force field deflection systems in key locations to eliminate the influence of various particles. Therefore, this method won't work within the civilization's territory. Only by getting the Xuan Star leader out of the territory can we have a chance to let particles drift into the civilization leader's body, thereby carrying out the assassination plan."
"If that's the case, Academician, we should immediately send a miniature spaceship to the territory of the Xuan Star Civilization to spread entangled particles. Our four-dimensional channel can allow entangled electrons or photons to continuously enter the territory of the Xuan Star Civilization. Perhaps we can find an opportunity to assassinate them without forcing the leader of the Xuan Star Civilization to come out."
"That probably won't work. We've tried many times, and we can't use a four-dimensional channel to transport entangled particles; the entanglement disappears after the transport."
"How so?"
"To give an analogy, a pair of entangled particles are like two pools of water, and their connection in the fourth dimension is like the pipes connecting the two pools. Now, if we try to stuff another pipe, or even more pipes, into this pipe, either the pipe that was stuffed in will burst or the pipe that was stuffed in will be flattened. That's roughly the idea. The thread that can go through the eye of a pin is finite, so a four-dimensional channel cannot guarantee that the entangled state of two particles will continue to exist."
"Academician, we abandoned quantum communication because quantum entanglement was disrupted by the spatial effects of warp drive. Now that four-dimensional transmission doesn't work either, are we left with only sub-light speed?"
"That's right. We need to extract the entangled particles outside the detection range of the Xuan Star Civilization, and then launch them into Xuan Star Civilization territory. We currently have enough antimatter storage; all we need is a small space or a small spaceship. We can then extract the entangled pair of photons through particle-antiparticle annihilation. Photons are very common in the universe and will not attract the attention of the Xuan Star Civilization; they simply cannot detect them."
"But Academician, this way we still can't track individual photons, and we can't accurately grasp the timing of opening the four-dimensional channel."
"Single particles are difficult to track, but we can use other methods to know their exact location. After the miniature spaceship collects all the data from the Xuan Star Civilization's territory, the computer can build an accurate model. Then, we can input the data of emitted photons into the computer, and the computer can know the exact location of each photon every second. Therefore, this operation also requires the computer to handle everything."
"Because photons have strong penetrating power, the time they stay in the brain of the Xuan Star Civilization is extremely short. Only computers can achieve such precise control. It is necessary to comprehensively calculate the photon speed, penetration time, channel opening time, the travel time of antimatter particles in the channel, and so on, and coordinate them perfectly to achieve the desired effect."
"Understood, Academician. That means it will be at least a thousand years before we can launch an attack. But that's fine too. More time to prepare means we'll have more antimatter and electrons, which will increase our chances of winning."
"General, we have another plan that we're ready to submit for implementation."
"Please speak, Academician."
"We call this the Seeding Plan. We've found a way to enter the fourth dimension, but we haven't been able to trace its origin. So we're trying to combine it with four-dimensional communication channels to obtain a method for tracing the origin. The initial progress is going smoothly, and the chances of success are high. So we're now preparing to seed the universe, releasing an endless stream of particles. If the experiment is successful, we can find approximate coordinates wherever we want to go."
"Wouldn't this attract the attention of other civilizations?"
"No, unless we establish a connection between two entangled particles, even we ourselves won't know where the other particle is. Moreover, there are countless naturally occurring entangled particles in this universe, so no other civilization would know. We can accurately simulate photons entering the territory of the Xuan Star Civilization using computers, but even if we use supercomputers to simulate photons entering the universe, we can only obtain some approximate coordinate data."
"Academician, if time permits, we will use a sub-light-speed spaceship to disperse these particles and find concealed locations to secure them, then activate them when needed."
"Not for now. We just need to create these entangled particles at a few specific points and release one of them. Then, we can use a computer to record the approximate direction and distance. When we need to use them, we can perform multi-point jumps, just like in a four-dimensional network. If we send a large number of spaceships to operate in the galaxy, it is very likely to arouse the hostility of other civilizations."
"However, we can still send spaceships to transmit photons to some key locations, allowing us to reach any point in a short time, and travel to nearby coordinates even faster. When we are stronger, we can carry out this work throughout the entire galaxy."
"Academician, is it possible to use this technology to infiltrate a civilization or other warships to cause sabotage?"
"Low-level civilizations might be able to, but advanced civilizations are unlikely, especially those in the advanced stages of Small Star Region. Most of them will have some level of dimensional technology, and they will definitely try to defend against such infiltration. Four-dimensional channels are still considered relatively advanced technology at our current stage, but at a higher level, almost all civilizations will discover the secrets of particles in the fourth dimension and thus make use of them."
"Alright, let's immediately dispatch a spaceship to a Xuan Star Civilization. The spaceship will hide inside the star to extract entangled photons, and then these photons, along with the star's light, will drift into the territory of the Xuan Star Civilization."
"I also need to go back to the lab to assist Academician Zhou Xiaohua in his research on fourth-dimensional travel. Mr. Daozi has provided us with a method to enter the fourth dimension. We must solve the problem of tracing the source. If we can find a way to travel in the fourth dimension and no longer get lost in four-dimensional space, we can stay in the fourth dimension for a long time, thereby solving the problem of dimensional attacks."
