Nima said indifferently: "To be exact, it is the urine of the two of us who are drinking." Rest assured, this water purification system was designed and manufactured by me, the water reduction rate has reached 98%, no additional water source is needed, just drinking our own urine is enough for us to return to the earth. ”

Bai Xiaofei was already about to vomit, if he hadn't thought that he was in space, the weightless flying of this spit out would damage the spaceship, and it would have been out of control a long time ago.

Whether Bai Xiaofei wanted it or not, he drank his own urine all the way - oh, no, drinking his own and Nima's urine, all the way to the sun.

After leaving the earth's orbit, there are no other countries to make a fool of themselves, after all, the vast majority of human outer space vehicles are in the earth's orbit, and there are very few human spacecraft after leaving the earth's orbit, and there are only a handful of countries that can sail in deep space or even outside the solar system, and the Americans have no chance to borrow "space junk" to create "traffic accidents" again.

And after all, outer space spacecraft have strict orbits and routes, and each spacecraft is worth tens of thousands of dollars, which has heavy scientific significance, unlike suicide satellites that can be sacrificed at will.

Nima seemed to know what Bai Xiaofei was worried about, and she comforted: "Don't worry, wars and conflicts in the universe are not so simple, you think about it, we are so far away from the earth now, and the radio signal will be delayed for several minutes when it comes and goes, in this case, the people on the earth can't accurately control the aircraft." Unless an enemy country is willing to launch a spacecraft to fight our Long March with real guns, there is no need to fear other covert means. ”

Astronautics is actually a long and boring thing, there is silence in space, there is no difference between light and dark, there is no difference between up and down, the sleeping place is a bag, put yourself in the bag, fix it on the bulkhead and sleep.

The crazy Nima has piled up every space of the spaceship with parts, and he doesn't even have the gym equipment necessary for long-term work in the universe - people in space must exercise regularly because of weightlessness muscles atrophy and bone loss.

Fortunately, Bai Xiaofei's ancestral exercises are quite magical, as long as he insists on running the exercises in space, not only is there no problem with the body, but there is a faint tendency to strengthen, Bai Xiaofei has some very ridiculous thoughts - could it be said that this set of exercises invented by Bai Qi is the most suitable for practicing in the weightless environment of the universe?

But he soon knew that he was thinking too ridiculously, during the Qin Kingdom, the ancients didn't even fly into the sky--the earliest flight of Yanhuang was the hundred households of the Yuan Dynasty--how could it be possible to take into account the universe and space?

Nima's body is also fine, she said that it was the immortal master who taught her a set of exercises, which is also quite effective.

As the Long March spacecraft marched towards the sun, Nima and Bai Xiaofei placed relay base stations in the depths of space, like a string of pearl necklaces, and this string of pearls will attract new fire and new light from the sun to the earth.

Finally one day, only the last and largest solar station left in the Long March spacecraft, that is, the main station, Nima and Bai Xiaofei looked at each other and smiled, success, only the last step is missing.

During this long space flight, there were only Nima and Bai Xiaofei, and after getting along for a long time, the two also formed a strong friendship - no way, what they saw when they opened their eyes every day was each other, and this was what Rijiu Sheng said - Bai Xiaofei found that Nima was just focusing on science and technology, and he was not strange in fact, but he spoke too straightforwardly, but he was somewhat similar to Ling Lan.

And Nima has also changed his opinion of Bai Xiaofei, although he has not received professional scientific learning, but he is quite talented in manipulating related instruments, to put it simply, he has a strong hands-on ability (Bai Xiaofei jumps on his feet, do you mean that my brain is simple and muscular?!). Several base stations in the later period were installed by Bai Xiaofei independently.

Nima suddenly turned straight at Bai Xiaofei: "Bai Xiaofei, I have an idea, I hope you can support me." ”

Bai Xiaofei said bluntly: "If you talk about something, who of us will talk to whom." "--That is, the relationship is so iron that they drink urine from each other.

Nima opened the navigation map: "Bai Xiaofei, originally our destination was here, this is already the farthest distance of the human spacecraft towards the sun, here, we will install a solar power terminal, and the Long March spacecraft will return, and the remaining burning is enough for us to return to the earth." ”

Bai Xiaofei was puzzled: "You booked this channel early in the morning, I don't know anything, what's the use of talking to me about this, you have the final say on what to do." ”

Nima stared at Bai Xiaofei: "It's really up to me to decide?" ”

Bai Xiaofei waved his hand: "Of course." However, as soon as the words came out, a sense of danger rose in his heart, ah, miserable, this Nima is a science madman, what idea she came up with, nine times out of ten it is full of risks, she should not have fallen into the pit.

Bai Xiaofei regretted that it was too late, Nima's eyes sparkled, and she pointed to the route: "Bai Xiaofei, I plan to cross the original set end point and continue to fly forward, a little closer to the sun, because you know that the closer we get to the sun, the more huge and pure the energy we get!" ”

Bai Xiaofei said dumbfoundedly: "Fly closer to the sun?" So, what about the burning we need on our return trip? There are no gas stations in this space. ”

Nima slapped his hands proudly: "We don't need to burn, the sun's rays can propel us back to Earth!" ”

Bai Xiaofei felt that his brain was not enough, and stammered: "Sunlight? How can sunlight allow us to return to Earth? ”

Nima pulled Bai Xiaofei's hand and spread his hand in the sunlight through the porthole: "How does your palm feel?" Bai Xiaofei said stupidly: "It's very warm." ”

--This is not nonsense, who doesn't know about solar heating, in fact, the sunlight penetrating through the porthole has been adjusted, and now that the Long March spacecraft is so close to the sun, if the sun's light shines directly on Bai Xiaofei's palm, his hands can be scorched.

Nima poked Bai Xiaofei's palm: "In addition to warmth, there is also pressure, pressure." ”

Bai Xiaofei stared at his palm, which was red by the sun: "Pressure? How can there be pressure? ”

Nima knocked Bai Xiaofei's forehead: "What did you study in college?!" Sunlight is mainly composed of photons, which are also a kind of particle, and photons hit the palm of the hand, of course, there is also pressure. ”

Although Bai Xiaofei majored in art, he finally knew that light was actually composed of photons, so he nodded hurriedly: "That's right, yes, there is pressure and pressure." ”

Nima said excitedly: "That's right, photons are under pressure, and when we build a new solar power plant, the pressure of the aggregated sunlight will be even greater, and I have calculated that we can use this aggregated light to propel our spacecraft back, and then send us back to Earth through the base station that follows Guò." ”

Bai Xiaofei's eyes rolled wildly: "Sunlight? Propel the spaceship? Return to Earth? He stretched out his hand again, reached out into the sunlight under the porthole, and raised his hand up and down—just by the pressure of this so-called photon? Your sister can't even push a feather!

Nima knew what Bai Xiaofei was worried about, and she patted Bai Xiaofei on the shoulder vigorously: "Ah, don't worry, I have calculated accurately, the light generated by the aggregation of the Guò solar terminal is enough for us to go home, think about it, if something really goes wrong, I won't die with you myself." ”

Bai Xiaofei cried with a sad face: "I don't seem to have the right to object, right?" ”

Nima said seriously: "You can object, but I definitely won't listen to you." ”

Bai Xiaofei rolled his eyes widely, then why are you still here to ask my opinion? Maybe this adventure is too dangerous, and I can't go to comfort me?

Nima took Bai Xiaofei's hand and said: "Come on, come on, we still have a lot to do - we need to reduce the weight of the spaceship, dismantle the cargo hold, and after the combustion chamber is exhausted, it can also be separated from the hull, and there is only one return capsule left." Well, the necessary living facilities are still needed, but our return journey is faster than when we came, so some of the excess living materials are just thrown away--"

Bai Xiaofei wailed, Lao Tzu will definitely never go on space travel with Nima again in the future!

So Bai Xiaofei became a demolition worker again, carried out the first demolition in space in history, knocked and beat, dismantled all the redundant facilities, and threw them directly into space, and with the weight reduction, the speed of the spacecraft increased again. The ground command station of Wuzhishan also discovered the abnormality of the spacecraft, and hurriedly called to inquire, Nima casually said a few times, only saying that he had optimized the flight plan of the spacecraft and concealed the change of course.

It's hot, Bai Xiaofei feels so hot, this is natural, because far beyond the original range, the distance between the Long March spacecraft and the sun is closer, and the original set air conditioning system is overwhelmed, which is no longer enough to reduce the temperature in the spacecraft. Now, Bai Xiaofei only wears a pair of pants in the spaceship, and Nima has also taken off into a bikini, but even so, he is so hot that he is sweating.

Only the pony corpse brother is getting better and better, standing in a small cage, walking back and forth, as if he wants to get out of the cage and receive more sunlight.

Bai Xiaofei swallowed his saliva and asked Nima weakly, "How long do we have to fly?" ”

Nima insisted and said, "16 hours, in another 16 hours, we will be able to return." She reluctantly smiled at Bai Xiaofei: "We have reached the closest distance between human beings and the sun, and we can go down in history." ”

Bai Xiaofei couldn't even roll his eyes: "Let's wait until we go back alive." I think we're the guy in ancient Greek mythology who flew to the sun with wax on his wings, and this unlucky guy ended up being roasted by the sun and fell to his death. ”
