As soon as Liu Feng stepped out of the cool cafeteria, he immediately felt the heat of the summer afternoon, and he walked briskly along a tree-lined avenue to a large lawn in the center of the campus, where the school library was at the other end.

Liu Feng is a native of Rongcheng, he is of medium stature and has good facial features, his face that looks honest and reliable reveals intelligence, and he has the general eloquence of Rongcheng people, but he is by no means the kind of person who talks about gossip news or rhetoric, in the group, he is the kind of person who either remains silent and listens to other people's high opinions or makes a splash and is reasonable.

When he walked to the center of the lawn, the mobile phone in his pocket rang, he took out his phone and opened it, and an image of an old man with eyes appeared on the small screen of his phone.

When Liu Feng saw the old man's dignity, he immediately shouted politely into the mobile phone screen, "Professor Ye, you haven't rested at noon?"

Then, he walked briskly to a nearby tree, shielding him from the scorching sun.

"Alas, in order for you to have a good final grade, where do I have the leisure to take a lunch break!" The old professor sighed and said, "Liu Feng, I just took the time to review the paper you sent me, although the writing is good, and there are almost no typos, but in my opinion, it is not so much an archaeological paper as a science fiction novel." Unfortunately, if it is too short when science fiction is published on the creation Chinese network, you see which of those famous online novels is not a hundred thousand words. ”

There was a hint of sarcasm in the old professor's tone.

Liu Feng's heart sank, he originally thought that the paper he wrote on the archaeological history of Sanxingdui was novel in content and beautiful in language, and he could get at least 80 good scores, and maybe it could become a fine product in Sanxingdui archaeology, but he didn't expect the professor to say that it was not a thesis!

"Professor Ye, are you mistaken? I have written a thesis in accordance with your outline, and I have listed several major archaeological discoveries from the past two centuries, and then presented my own arguments to explain them. Liu Feng argued.

The professor's tone became serious: "I can see that you have a good writing and a lot of imagination, and these skills will undoubtedly be useful in writing science fiction." When I was young, I also read a lot of science fiction novels about the Sanxingdui civilization, why because the aliens fell in love with the princess of the ancient Shu Kingdom, so they stayed to help the ancient Shu people make bronzes, and what Sumerians helped the Shu people build cities because they liked the silk of the ancient Shu Kingdom.

But as my knowledge grew, so did the illusions, and now I realized more deeply that archaeological history is as rigorous a science as mathematical physics, and that there is no need for the slightest conjecture. You have discussed several major problems in the archaeological history of Sanxingdui with the intervention of extraterrestrial civilizations, although the explanation is quite satisfactory, but the evidence is insufficient, or it is groundless.

The archaeological community has been interested in whether there is an alien civilization in Sanxingdui civilization for two centuries, and I was also an alien when I was young, but with the in-depth study of the ancient civilization of Sanxingdui, the ancestors of our Shu people had enough wisdom to create such a brilliant ancient civilization on their own. Liu Feng, Sanxingdui archaeology is very profound, you haven't started yet, don't think that imagination alone can solve two centuries of unsolved difficult problems. ”

Liu Feng said unconvinced: "Professor Nie, your views just now are inconsistent, since the arguments I put forward can satisfactorily explain several difficult issues in history, it shows that my arguments are reasonable. Don't forget, the history of science tends to put forward hypotheses first and then seek evidence, and after Eins's general theory of relativity, few people in the world understood it at first, let alone had no factual basis, but it was repeatedly proven to be the truth. Not to mention that I presented my own strong evidence in my dissertation, my grandfather's cousin..."

"You don't need to mention your grandfather's cousin!" The old professor unceremoniously interrupted Liu Feng's defense, "I carefully reviewed the part you wrote, it was just another small story in the science fiction story. It may be true that your grandfather's cousin's family suddenly disappeared a century ago, but it would be far-fetched for you to confuse their disappearance with the Sanxingdui Museum and then link them with aliens, so it is impossible to prove your argument.

Liu Feng, you are still young, there are still a lot of basic archaeological knowledge to learn, remember, to study archaeology and culture, you must use a rigorous scientific spirit to explore the truth, not with your own imagination to make things up! You hurry up and rewrite it and send it to me before this time next week! There will be no grades after the expiration, I will go to Northern Europe to live for a while in a few days, and this place in Rongcheng is a big furnace in the summer like the mountain city. ”

After the old professor finished speaking, the image disappeared from the screen of Liu Feng's mobile phone.

The professor's reprimand made Liu Feng's mood that had just turned cloudy and sunny again shrouded in dark clouds, and he had no intention of going to the library to write a paper again, thinking that even if he gave up his lunch break to concoct a paper, he might be ridiculed by another harsh professor.

He sat feebly on the grass leaning against the trunk of a tree and closed his tired eyes, at this moment he felt that he had to think about his past and future life, and the current situation made him realize that he had made a big mistake in choosing to study archaeological history a year ago.

Liu Feng has actually been fascinated by the starry world since he was a child, and has always dreamed of having the opportunity to travel to the outer world in this life. On the eve of graduating from high school, he did not choose aerospace university, but stayed in his hometown to study archaeology, and the reason was still very good a year ago.

First of all, his grandfather was an aerospace technician, and his grandfather was a strong motivation to pursue a career in aerospace when he was young, also because he believed that there were signs that his cousin Lin Xiaolan's family was taken to the outer world by aliens.

But Liu Feng's grandfather has worked in the aerospace field for nearly fifty years, at most a month on the lunar space station, according to his grandfather's retirement statement, if there are no major unexpected historical events, it will take at least one or two centuries for earthlings to build an interstellar spaceship.

This undoubtedly means that even if Liu Feng is engaged in the aerospace industry like his grandfather, he will not have the opportunity to travel to the outer world in his lifetime.

And his fellow Bashu countryman, Dr. Wang, only returned to the earth world after he had already studied at university here.

Another important reason why Liu Feng chose to major in archaeology and history is because he was fascinated by the Sanxingdui civilization in his hometown, he browsed a lot of archaeological discoveries and historical stories about the Sanxingdui civilization in middle school, and he also read a lot of science fiction novels that describe aliens' participation in the Sanxingdui civilization.

The disappearance of his grandfather and cousin's family made Liu Feng firmly stand on the side of the alien faction, believing that the Sanxingdui ancient civilization must be related to the participation of alien civilizations.

Therefore, Liu Feng finally chose to study archaeology and history at Rongcheng University, and took the demonstration of aliens' participation in the ancient civilization of Sanxingdui as his research direction.

But two things that just happened today made Liu Feng have to reconsider the direction of his life.

Dr. Wang's speech undoubtedly announced that the earth world will soon enter the era of interstellar navigation, and aerospace science and technology will dominate the scientific and technological and social development of human beings on earth.

And Professor Ye's complete rejection of his thesis means that it will only be a waste of time and tuition to continue reading this major.

Liu Feng is an assertive person, and after carefully analyzing the current world situation and his own situation, he quickly made a decision in his heart.

Liu Feng's mother came home from work and was a little surprised to open the door and see her son in the house, because at this point in time, her son must be running around on the sports field and playing football.

"Ah Feng, why did you go home so early today?" Liu Feng's mother asked, although she is over forty years old, she has maintained a good figure, and she has the fair complexion and gentle temperament of a Rongcheng woman.

"Mom, I decided to drop out of Rongcheng University and change to aerospace technology next semester." Liu Feng stepped forward and said to his mother.

"Why?" Liu Feng's mother asked, although she was a little surprised, she was not particularly surprised, because she was not very in favor of her son studying archaeology, but young people in this era are used to making their own decisions.

Liu Feng told him what happened today.

Liu Feng's mother nodded in understanding: "Our teachers and students have listened to Dr. Wang's speech today, it is indeed very surprising and inspiring, it is also a good time for you to change your study of aerospace technology, but there is no aerospace university in Chengdu, if you want to study aerospace science and technology, you have to go to school in other places, and the accommodation fee alone will cost a lot of money." ”

"Mom, I already have a way to make money, which is to buy and sell antiques. One of my classmates found a few silver coins commemorating the founding of the People's Republic of China from his grandfather's house, and two hundred years ago, only one round of ancient silver coins was auctioned at the auction house for 1.5 million. I plan to go to Grandpa Lion Rock tomorrow to look for not only ancient silver coins, but also bronze coins, ancient porcelain and ancient furniture. In addition to my grandfather's house, I can also visit the folks in the mountains to see if they have any antiques to trade. ”

Liu Feng's mother said: "If you want to talk about antiques, the ancestral houses where your grandfather lived in the mountains are them, but it is difficult to say whether there are valuable antiques in the house, you can go for a trip, your grandfather is over ninety years old, he will not be there in the future, and I am afraid that no one in our family will live there." Since you are there, stay with your grandfather for a few more days and talk about what to do with those ancestral houses in the future. ”
