"Uncle doesn't know yet, Mr. Wu, Grandpa has also become a well-known figure in the earth world in the last century because of you, and you have gained fame and fortune!" Wang Si said with a smile.

"Are you saying that the book written by Mr. Wu has really become a world masterpiece?" Wang Fan asked with a smile, he always thought that although Mr. Wu was just an ordinary teacher in the mountains, he was always prescient.

"Uncle, Mr. Wu's grandfather's books are not just ordinary world classics!" Wang Xing said excitedly, "His books have not only been adapted into various versions of film and television animations by the world, influencing the childhood of generations of earthlings, but his books have also been studied as valuable materials by various scholars and various intelligence agencies." ”

"Uncle, don't you know, that book brought more than one billion yuan in copyright income to Mr. Wu's grandfather, which was a lot of wealth more than a hundred years ago! I heard my father say that Mr. Wu's grandfather wanted to give half of the money to my grandmother back then, saying that my uncle co-wrote the book with him, but my grandmother refused to ask for a penny.

So, Mr. Wu's grandfather used his money to build a hospital in Fengcheng, called Xingkong Welfare Hospital, and the names of the donors engraved on the stone tablet at the gate of the hospital were Uncle and Mr. Wu's grandfather himself. My uncle and my dad were both in charge of this hospital, which is still the best hospital in Fengcheng and has been providing free treatment to poor patients since its establishment.

Because of this, Mr. Wu's grandfather was not only famous all over the world when he was alive, but he also won the gratitude of countless patients. Before his death, Mr. Wu's grandfather said that he was very satisfied with his life, and the only regret was that he was not able to see his uncle again before he died. When Wang Si said this, the old man's face showed a sad look.

Wang Fan felt a lot of emotion in his heart, and he didn't know what to say for a while.

Suddenly, his niece and granddaughter shouted excitedly: "Dad, we are happy to forget an important thing, Mr. Wu's grandfather left my grandfather a book before his death, and there is a letter in it that our descendants want to pass on to our uncle!" ”

Wang Fan was pleasantly surprised, he looked at his old nephew and asked, "Is it?" ”

At this moment, a red-body intelligent person walked into the living room and said, "Professor Wang, dinner is ready, please take a seat!" ”

Wang Si stood up on crutches and said with a smile: "Uncle, let's eat first, Mr. Wu's grandfather's letter is locked in the safe in my room and can't run, and it's not too late to wait for my uncle to eat and drink enough to lie on the bed and read it slowly." ”

Over dinner, Wang Fan briefed his two juniors about his experience of studying and living in Rasxing.

After dinner, Wang Xing arranged for her uncle to stay in the room where he used to live.

The room has been tidy and tidy, and although some facilities have been added to the room that are necessary for modern life, the wooden bed, wooden table and chairs that Wang Fan once used are still placed there. His used small alarm clock, pen and exercise books, as well as books he had read, were neatly placed in a sealed glass bookcase.

It's just that those books and papers have been yellowed after nearly a century and a half, and Wang Fan finally felt like home when he walked into the room and saw these items he had used.

The letter left by Mr. Wu had been placed on the wooden table, and Wang Fan sat down at the table, and a soft light immediately shone down from the ceiling overhead and shone on the cover of the book.

Wang Fan picked up the book, and the book was kept very well, although it was still as new after a hundred years. On the cover of the book are written four bold words: Starry Sky Holiday.

The cover illustration shows a young man from a mountain village standing in a valley with a kitten on his back, looking up at the blue sky, and a golden spaceship looming in the sky.

Wang Fan opened the title page of the book, and there was a sealed envelope inside, on which were written four very individual words: Wang Fan personally opened.

Wang Fan carefully tore open the seal, took out the neatly folded letter from it and opened it, and Mr. Wu's neat handwriting caught people's eyes:

Wang Fan, I was no longer alive when you read this letter, although I regret not being able to see you again before I die, but I am not sad, because I have always believed that you will be safe and sound in the outer world, and I have always believed that you will definitely return to earth after completing your study and life in the outer world. Because I always remember that your ideal is to help the earthlings build the most advanced spaceship, and you are the kind of person who unswervingly strives for your ideals.

You don't have to be sad when you read my letter, my life has been transformed into the words in your hand and I am with you.

Wang Fan, you were still young when you left home, maybe you don't know my situation when I was young, I only studied with a private teacher in the village for three years when I was a child, and then I had to drop out of school and farm because my father died of illness and had no source of livelihood. Although I helped my mother get up early and work in the mountains at night, she still did not have enough food and clothing. But I insisted on reading and studying by myself every night under the oil lamp, so that after a few years I was literally good enough to teach in the mountains, and so I was lucky enough to be your teacher decades later, and because of a student like you, my ordinary life became extraordinary.

Wang Fan, although I have no worries about food and clothing in my later years, I am very worried about the future of our human beings on earth. The fact that Lord Hu Tang invaded the earth proves that the earth world is in internal and external troubles, and the human beings on the earth have been fighting and killing each other for thousands of years.

In the earth world after entering the 21st century, human beings already have nuclear weapons that can destroy everything on this planet many times, so if the conflict of interests and the threat of war between the countries of the world on the earth cannot be ended, not only will the earthlings not be able to unite against foreign invasions, but the earthlings are likely to self-destruct in the near future.

I believe that the establishment of a government of the earth that represents the interests of the whole world, using the United Nations as a framework is the best way to ensure the long-term peace and stability of mankind on the earth. The biggest difference between this future earth government and today's United Nations is that it has taken over the military command of all countries in the world and formed an earth government army, whose role is to maintain world peace internally and resist the invasion of lawless aliens externally.

Wang Fan, when you read this letter, maybe the human beings on earth have realized my above-mentioned ideals, or maybe the situation is worse than the contemporary era in which I live. If the current state of the world is the former, I am happy for you in heaven, because in a peaceful and unified earth world, you will become the best scientist in the earth world when you return, so as to lead the earthlings to build the most advanced spaceship, and therefore, the earth world will not be far away from becoming a developed world in the starry sky.

But if you come back to Earth and find that the situation of the world is worse than I expected, Wang Fan, I suggest you think more about the current situation and future of human beings on Earth. Because in a state where war between countries is on the verge of breaking out, you will face a great crisis when you return to Earth.

If the human beings of the earth cannot achieve the peaceful unification of the whole world by their own strength, then they can only hope for the help of external forces, and I think you will have a way to do it.

Because when you were a teenager, you once brought an alien force of justice such as the Space Police to defuse an alien invasion for the earthlings, and now you are more capable of helping the earthlings establish a strong earth government and realize the millennium dream of world harmony.

Wang Fan, no matter what kind of situation the earth world was when you read this letter, as long as you have the determination and courage, you can do something great that will affect the future development of the earth world, and your great achievements will be recorded in the history of human development on the earth.

I will cheer you in heaven!

After reading the letter, Wang Fan's heart was surging.

He raised his eyes and looked out the window, the city lights at night were like a sea of stars, this is the prosperous world created by the human beings on the earth, and destruction or progress are the two futures and destiny of the human beings in this world.

The proposition of the survival or destruction of humanity on Earth is undoubtedly far more important than the ideal of building more advanced spaceships.

Although Wang Fan has just returned to Earth, it is not difficult to infer from the information reflected to him by his younger generations that the current situation of the Earth world is not much different from that of a century ago, except for the fact that it is more urbanized and information-based. There are still several military powers vying for hegemony, but the focus of modern competition is space technology and space warships.

Wang Fan recalled what Mr. Wu said in his letter, Mr. Wu was reminding himself that if the earth world was in turmoil when he returned, he should be more involved in the cause of maintaining the peaceful development of mankind.

When he was a teenager, Wang Fan believed that Mr. Wu was always prescient, and now that he has grown up, Wang Fan still believes in Mr. Wu's foresight, and the advice that Mr. Wu left him a hundred years ago must be taken seriously and thought deeply.
