At this moment, before Gu Jin's brainwave consciousness was fully expressed, a huge amount of information suddenly flowed into his consciousness, making his brain feel a strong dizziness again:

“...... This is a new era of human space-time technology...... Mending the Temporal Rift Mission...... Presenter: Nicole, Communications Assistant...... Planned Supplies...... Spatiotemporal Labeling Plan...... Earth Federation ...... The Great Council Temporal Authority...... 1st Class Rhea Time Tunnel Patrol Ship ...... Hurry! In order to avoid the collapse of the tunnel, emergency energy traction is required to merge the space...... Tunnel closure completed...... Warn! Warn! There are signs of intelligent life in the matter of different time and space...... Emergency Contact Time and Space Authority ......"

"Wait! I'm dizzy! Still nauseous and want to throw up...... Uh, I can't digest it...... I don't understand the message you're sending! ”

"Oops! I'm sorry! I'm sorry! The amount of information in the unit is too large, I'm sorry, it seems that the information flow has also been inverted, hey, professional equipment such as advanced quantum brainwave AC machine, I am not very proficient in operation, this is Anna's job! But he's not ...... now."

Nicole looked back at Gu Jin who was struggling in the chaos with an apologetic expression, and hurriedly fiddled with a bunch of unknown instruments.

"Anna is my engineer, but she's still busy outside! I can't operate this kind of complex batch information injection, so let's ask me and answer it, although it's a little verbose, but it's better for you and me. ”

Nicole finally finished the shutdown process, then turned her head to look at the patient who was almost fainting.

"So, who are you?"

The brainwave signal sent by Gu Jin subconsciously was transmitted to the signal screen of the instrument.

"You can call me Nicole, I am the project leader of the Temporal and Spatial Labeling Project of the Temporal and Spatial Administration of the Federal Parliament, and the communication assistant of the former first-class temporal tunnel patrol ship Rhea."

"Which federal parliament?"

"Earth Federation!"

"This ...... Well, what is the Temporal Authority? ”

"A subordinate body of the Great Council of the Earth Federation."

"All I know is a UN ......"

"Oh, I forgot to tell you, for your time, of course, this institution does not exist, because this is a form of government that exists more than sixty-five thousand years after the United Era of Christ and Buddha on the Gregorian calendar of the earth."

"What?!"

"Yes, you heard it right, I just said it, it's more than sixty-five thousand years later! We are the people of the future, as you can understand it now, the people of the future who have traveled back to your time to carry out a scientific mission. ”

"Well, what have I seen of you these days? Brainwave communication, and medical technology, I choose to believe what you say.

Well, futuristic people, then, what is a space-time marker...... What kind of plan did you just say? ”

"The Spatio-temporal Annotation Project, which is a scientific research project, is one of the founders of this project. Back then, oh, it was twenty-five years ago for me, and for you it was sixty-five thousand three hundred and sixteen years and three months from the future...... Uh, I noticed that your brain wave state is unstable, do you want me to continue to talk about the situation? ”

Nicole noticed that the other party's brainwave pattern was confused, and quickly stopped and asked.

"Any normal person will not be shocked after listening to your above statement, I'm fine, please continue to introduce!"

"Okay, I was working as a communications assistant on a space-time tunnel patrol ship, well, it's actually a miscellaneous ......"

"Time and space tunnels? Does humanity have a space-time tunnel? ”

"Do you think that more than 60,000 years later, human beings will not be able to develop space travel technology such as space-time tunnels?"

"Oh no, I'm just curious, no wonder you've traveled back in time to our time."

"You're wrong again, it's completely different from what you think, our space-time tunnel can only be used for interstellar physical travel, just like the highways of your time, the only difference is that the two ends of the space-time tunnel are connected to different galaxies. Although interstellar travel and time travel are essentially the same, at the level of specific technical operations, they are two completely different things, do you understand? ”

"I understand, but I don't quite understand, this plane ...... Belch...... Well, please go ahead and ......"

The keen Gu Jin found that Nicole was looking at him with a helpless look at him at this time, so he quickly stopped further questioning.

“…… During a routine Temporal Tunnel Patrol mission, we discovered a temporal rift, which is common in Temporal Tunnels, and one of the tasks of the Temporal Tunnel Patrol Ship is to repair the rift in the tunnel at any time, just like your Orbital Maintenance Patrol Car. ”

"So? Sounds cool. ”

"Of course, so we started the routine tinkering, and at first everything was fine, and then something happened......"

"Oh? And so you crossed? ”

"No, it's actually you people from this time and space who have traveled to our time!"

"Such a coincidence? How did it happen? ”

"Because of the sudden expansion of the rift in time and space.

Actually, it was a sudden accident, and later we found out the truth, it turned out that there was a high-speed rotating pulsar hundreds of light-years away from our tunnel, and at that time, its odd array of particles happened to be transferred in energy, and a powerful quantum stream was ejected outward......"

"Nicole, I don't understand ......"

"Oh, by the way, with the level of technology in your time, you can't discuss it to this extent, in the terminology of your time, let's call it gamma rays.

Due to the sudden and strong burst of this particle stream, and at the time of the eruption, it was aimed at the rift in our space-time tunnel.

As a result, the intense rays cause our energy sustaining ring to briefly engage in protective self-shut-up, albeit for only three seconds...... Well, I won't talk about the specific technical details, because you don't understand it, in short, this space-time rift has suddenly expanded! Not only did we fail to patch it, but we also triggered a space-time vortex that allowed other-space-time matter to enter our space-time tunnel! As I told you, these other-space-time substances actually come from your timeline! ”

"From our time?"

"That's right! Your time! After a lot of twists and turns, we finally figured out that fact, and then, we were a little bit excited, well, you know what it meant for us to be surprised? ”

"Does it mean that you have finally opened a space-time path that humans can play through?"

"That's right or not, strictly speaking, it means that humans can finally start thinking about autonomous crossing!"

"I don't understand...... Is there any essential difference between autonomous and non-autonomous traversal? ”

"From a pure time travel point of view, of course it's no different! However, you must know that the universe we live in has a history of 30 billion years, and if you passively and randomly travel through this 30 billion year timeline, do you think you can travel to the historical time period of our intelligent creatures, and not some other civilization, or even the era of famine? This universe has a timeline of 30 billion years, which is very long, isn't it? ”

Gu Jin just nodded knowingly and didn't speak this time, looking like he was listening, although this was just an illusory scene in his mind, Gu Jin still responded to Nicole's rhetorical question very seriously.

So Nicole continued with satisfaction:

"In fact, in the three thousand years since humans built the space-time tunnel, they have often encountered the entry of materials from different time and space, and in terms of timeline, 99.9999 percent of them ...... Well, it doesn't matter if you add a few more nines---- the more space-time matter above all comes from the distant interstellar era, or from the early days of the formation of the solar system, or even more advanced cosmic periods. At that time, the sun was just a cloud of fog, and the earth was not even a small fireball. ”

"I seem to understand something, the current history of human civilization is only 5,000 years, right? If it happens by chance......"

"Space-time vortex."

"That's right, relying on the path opened by the space-time vortex by chance to travel through time and space, for the timeline of 30 billion years, the probability of traveling to these 5,000 years is too small!"

Hearing this, Gu Jin finally understood a little.
