Lu Ziming and the others naturally couldn't attend any meeting to welcome the king, so they were led into a tent to rest and wait for news.

He looked at the time on his watch, there were still 6 hours at the earliest, and the rat tide would reach Saiying Mountain, and if there was no news after three hours, he was ready to leave here alone.

"Lu! You just said that there is a rat tide, is it true", there were only three people in the tent, Lu Ziming, Adita and David, and Haribari had already returned to the camp of his own people.

"Do you think I look like a liar?"

"Road! I don't ask how you know, can you take the two of us with you when you leave?" David saw that Lu Ziming didn't even put down the mountaineering bag on his body, this was to prepare for leaving.

"Why should I take you?" "It's better to run one than three, and it's still two ordinary people, isn't this uncomfortable for yourself?

"Lu! I know the two of us are a burden to you, and we will drag you down. But if you're willing to take the two of us out of here, I'll tell you a secret?"

"Secrets! Do you have any secrets that have anything to do with me?"

"Yes!" David looked around nervously, leaned over to Lu Ziming's side and whispered: "This is a secret about the outbreak of the virus, and there are very few people who know this secret, don't you want to know what the virus is?"

Lu Ziming looked at David staring at him nervously, and his heart moved slightly, he had heard Li Zheng guess a long time ago that the so-called virus did not exist, these are just official words, what it is, Li Zheng himself does not know.

"You say first, I don't like people to lie to me, and if I find out you're lying, I'll abandon you for anything?"

"You'll promise us to get us out of here?" Adita said suddenly.

"Yes, as long as the secret you are telling is really a secret, I promise you to take you away, but I am not capable of sending you home, you have to think about this yourself. ”

David immediately replied, "It doesn't matter, just take us to your country and hand us over to your government or army."

Lu Ziming thought about it, if what David said was really a secret about the virus, he could indeed consider bringing them back to China and handing them over to the government or the army.

Maybe Lu Ziming still has this bit of credit in David's heart, he pondered for a while, looked at the outside of the tent, poured himself a cup of milk tea and said, "Road! You haven't heard about the Voyager probe?"

Lu Ziming nodded, what are you kidding, if you haven't even heard about the Voyager probe, are you still an earthling?

He remembers it well: "The Voyager 1 probe is an unmanned outer solar space probe developed by NASA, launched on September 5, 1977, and was still operating normally until the outbreak of the virus. The Voyager 2 probe, the second of two space probes developed by NASA to fly outside the solar system, was successfully launched from the Kennedy Space Center on August 20, 1977, initially as Mariner 12 in the Mariner program. It became the sister probe to Project Voyager 1 (also known as Mariner 11). ”

David nodded appreciatively and said: "What you said is not wrong, the purpose of the two Voyager probes is to explore the major planets in the solar system, but their final destination is to fly out of the solar system and explore space beyond the solar system, so do you know the fate of their two probes later?"

What kind of international joke, how could he know the final fate of the two Voyager probes, he asked rhetorically, "Does this have anything to do with the secret you said?"

"Of course it does, you listen to me slowly", David's expression suddenly darkened, as if there was something pressing him and he couldn't breathe: "You may not have heard of the Kuiper belt, which is a dense hollow disc-like region of the solar system near the ecliptic plane outside Neptune's orbit (about 30 AU from the sun)."

David is really capable of pulling, Lu Ziming felt that he was about to take David to the outer solar system, so he listened patiently.

"The Kuiper Belt is sometimes mistaken for the boundaries of the solar system, but the solar system also includes the Oort Nebula, which extends outward two light-years. In the Kuiper Belt, there are a large number of meteorites and asteroids, ranging in diameter from thousands of meters to thousands of kilometers. None of this was there, but the two Voyager probes mysteriously disappeared as soon as they arrived in the Kuiper Belt?"

Lu Ziming said disapprenously: "Either it was crashed, or it was interfered with by some radiation and lost contact."

"You're right, a lot of people think so, this kind of disconnection often happens in the exploration of Mars, and it is not surprising, but then an incident happened that completely changed everyone's mind. On October 19, 2008, NASA launched an Interstellar Boundary Probe (IBEX), do you know what happened?"

Seeing Lu Ziming's dazed face, David's eyes were full of sadness and said: "ibex has happened to the boundary of the solar system, an unknown and impenetrable boundary, do you know what this means?"

Lu Ziming said without thinking: "Enclosed space! We live in a huge enclosed space?"

"Enclosed space!" is a good word", David didn't expect Lu Ziming to come up with such a sentence, and looked at Lu Ziming in surprise and said: "Maybe, the astrophysical community was shocked at that time, NASA thought that IBEX was malfunctioning, and the government immediately blocked the news, and there were no more than 100 people who knew about it at that time, and I also heard other parties talk about it later, and I was also shocked and frightened." You don't seem shocked, but you don't understand what that means, and it's useless to sue you now, it's already happening."

Later, NASA secretly made several more realizations, all of which were aimed at the boundaries of the solar system, and the results were dismal. This invisible boundary, which exists in the Kuiper Belt, encloses the entire solar system, and no object, including meteorites and asteroids, can pass through, and human beings live in a huge enclosed space and cannot take half a step into the solar system. ”

Lu Ziming didn't believe what David said: "Then what's going on with the Milky Way we see when we look up now, don't sue me, those are all window grilles on the windows?"

"Almost, you can understand it this way, the Milky Way we see, and even the space scene we see with the Hubble telescope, are actually the scenes that remain on this film of enclosed space, and they are remnants of the ...... many, many years ago. ”
