Wang Fan was very happy to hear that Song Ren and Sun Xiu had created extraordinary achievements in the old world. He smiled: "According to my calculations, the time span of Venus is only about a quarter of that of the Earth, and Song Ren and Sun Xiu should still be alive in the Outer Heaven Country, so I will go back there to see them later." ”

"Uncle must take me then!" Wang Xing's expression and tone of voice were like a little girl who was coquettish to her elders.

Wang Fan smiled: "Okay, I will definitely bring you then!" ”

"I also want to go to the golden world outside the sky, but unfortunately it is too old, it is said that the gravity of that world is much greater than here, and it is even more difficult for me to get to that world. Alas! Wang Si sighed.

Wang Xing comforted: "Dad, when I go to gold with my uncle, I will take pictures of the scenery and people I visit along the way, and when you come back, there is no difference between going there and going in person." ”

Wang Fan changed the topic and asked Wang Xing: "Where is your great-grandmother and grandfather's cemetery?" I think the first thing I'm going to do when I come back should be to sweep their graves. ”

Unexpectedly, the expression on Wang Xing's face suddenly became serious, "Uncle, there is a public cemetery in the western suburbs of Fengcheng, and our family has already bought a small cemetery in it. But I'm afraid it's not very convenient for my uncle to go there, if my uncle must go, we must first report to the Ministry of State Security, and wait for the permission of the Ministry of State Security leaders to arrange security work before my uncle can go. ”

Although Wang Fan had vaguely guessed the reason, he still couldn't help but ask: "Why?"

"Uncle, it has been one hundred and thirty-seven years since you last left the earth, and decades after you helped the earthlings defuse the invasion of the earth by the general of Baguo, the story of your uncle has been adapted into various versions of movies and cartoons that have been widely spread around the world.

Moreover, because my uncle is recognized by the earth world as the only earthling who has close contact with humans on developed planets, and my uncle then went to study and live in the developed world, it is not difficult to imagine that the news media and intelligence agencies all over the world are very eager to obtain information about my uncle, and this is my uncle's home, so it has naturally become the focus of attention of journalists and intelligence spies from all walks of life around the world.

In order to protect our home, the Ministry of National Security first sent a company of agents to guard around this residence. That situation lasted for ten years, because my uncle did not come back, and there were no more incidents of aliens coming to Earth, and the place gradually calmed down. But the Department of National Security still has a squad of agents stationed to guard our residence.

After another thirty years, because my uncle still did not come back, and no accurate information was found about aliens entering and leaving the earth, the whole world believed that my uncle would not return to Earth for various reasons, and the Ministry of State Security withdrew all the security personnel.

However, this does not mean that the earth world has completely forgotten my uncle since then, when my father and I went to our cemetery to sweep the grave during the Qingming Festival this year, we unexpectedly found several miniature cameras hidden in the flowers, indicating that there are unknown spy agents still monitoring us, everyone would have thought that if my uncle came back, he would definitely go to that cemetery to pay respects to his relatives.

However, my uncle can rest assured that we have installed the most advanced anti-espionage facilities inside and outside this residence, plus there are two intelligent assistants with counter-espionage functions living here, ordinary spy officers cannot get close, and my uncle will not be noticed by the outside world if he lives here for a short time. ”

After hearing this, Wang Fan nodded to his niece and granddaughter in understanding.

Wang Si continued his daughter's words and said: "Uncle, Xingxing and I have already signed an agreement with the Ministry of State Security, promising to report to them immediately if there is any information about you, and the purpose of the Ministry of State Security is also to protect my uncle's personal safety after returning to Earth." Uncle doesn't know yet, Xingxing and I originally worked in the space technology department under the Ministry of National Security before we retired, we are both soldiers, and soldiers must obey orders.

However, my uncle is now home, and as juniors, we will first carry out my uncle's orders, not to mention that Xingxing and I have both retired, so it can be said that we will not be affected by the king's life. Uncle doesn't want the Ministry of Homeland Security to know you're home, right?" Wang Si said, a smile on his old face.

"It's better to keep it a secret for the time being, otherwise we may not have enough time to sit here and talk about common things," Wang Fan said with a smile, "I am very grateful to the Ministry of State Security for caring so much about me." The information I got from outside the sky is that the earth world has not yet been unified, and countries are still competing with each other and even local wars are often occurring, is this the current situation? ”

"That's right!" Wang Xing said, "The focus of competition in the world now is precisely space technology, because the space army is already the most important military force of mankind on earth, and the air and space warships are the core equipment of the space army." Whoever has a super-powerful air-space warship can dominate the resources of the earth and extraterrestrial space.

Although there are still more than 100 independent countries in the world today, there are only a dozen or so military powers in the space army that have actual combat effectiveness, and other countries are dependent on a certain military power for protection according to their own interests. China is a large country with a large population and economy, and it also has a powerful space force, but in the past ten years, country X has surpassed China in some key areas of space technology, so the performance of their air and space warships has improved rapidly, and the strength of the space force they now have has made China feel a lot of pressure.

If the heads of the Ministry of National Security learned that their uncle was here, they would definitely be eager to come and meet with him, and they would like to know if his uncle had brought back some information on space technology from developed planets. And, no doubt, they will salivate over their uncle's spaceship that can travel through interstellar space, ha..."

Wang Fan said with a smile: "If they ask me sincerely, I will not let them down, because I have completed a doctoral course in spaceship technology at Russ Star, and this small spaceship is also assembled by myself." ”

Wang Si and her daughter glanced at each other knowingly.

Wang Si smiled: "We already anticipated what my uncle would do, because I heard my grandmother and father often talk about it, and my uncle's dream when he was young was to build a spaceship that traveled through time and space. Uncle, because you have such an ideal, Xingxing and I have also aspired since childhood and devoted our lives to the spaceship business. It's a pity that we didn't have the opportunity to go to the extraterrestrial developed human world to study like our uncle, so despite our lifelong efforts, we achieved little results. ”

Wang Xing laughed and said: "Uncle, you are our senior, my father and I have a lot of mysteries about space technology that we can't solve, and you have the responsibility to help us." ”

Wang Fan smiled and nodded.

Wang Si continued: "Uncle, what are your plans for coming back this time?" I believe that this era is the best time for my uncle to realize his ideals, and if my uncle is willing to stay and work, the leaders of our Military Commission and the Ministry of State Security will definitely be happy in their hearts, and they will definitely meet all the conditions put forward by my uncle. ”

After Wang Si finished speaking, he and his daughter both looked at their young seniors with a smile, their eyes full of anticipation.

Wang Fan smiled: "I plan to stay here this time, I am glad that you are peers, and I hope you will help me find a suitable work unit to develop a spaceship." I know from the information about Russ that the maximum speed of the earthlings' current spacecraft in space is still far below the speed of light. However, don't expect too much from me, although my theoretical knowledge is far more advanced than the current theories on Earth, I lack practical work experience. ”

"Great!" Wang Xing high-fived and cheered, and her happy demeanor made her a lot younger all of a sudden.

Wang Sile couldn't close his mouth and looked at his young uncle and smirked.

"Uncle, just by assembling the spaceship outside and crossing the starry sky to the earth, you are the unparalleled scientific superman of the earth world!" Wang Xing's tone was excited and resolute, "My dad and I have already thought about the most suitable work unit for my uncle when he returns home, but despite this, it is best for my uncle to go and inspect it himself before making a final decision."

That unit is a space technology center where I worked before I retired, and it's located at a military base under the Ministry of National Security on the eastern outskirts of Beicheng, and the current base commander is a student of mine when I was teaching at the university. Later, he became the main leader of this military base, and I was hired by him to work there for a few years after I retired from university.

We also had a good personal relationship, because my father, who was a student commander, worked in my father's department when he was younger. Both father and son are decent people, serious and responsible, and we are most relieved if my uncle works with him. And he needs his uncle's support the most now, and I promised him that if he comes back, he will take him to visit his technical center. ”

"Okay, I'll listen to you, we'll go there tomorrow." Wang Fan said with a smile.

Outside the window, twilight fell, but the interior grew brighter, with a soft light coming from some kind of light source hidden in the ceiling and walls.

Wang Fan's two juniors are more and more interested in talking, they talk to the younger seniors about the family, and soon, the topic falls on a person Wang Fan often misses outside the family: Teacher Wu.
