Qi Feiyang said: "The universe is always changing, any object has a life cycle, the earth and the solar system and even the entire universe will die out sooner or later, so does it mean that all living things, including human life, are actually meaningless, just a passerby in the evolution of the universe." ”

Professor Tan nodded and said, "That's right, you can imagine the universe as a giant creature, the planet is its cells, and humans are equivalent to viruses that invade the cells. ”

Yang Bishan asked, "Professor Tan, do you think the universe has boundaries?" If the universe has boundaries, then what is outside the boundaries? ”

"First of all, you have to understand the definition of the universe, the universe is the general term of time, space and matter, and now we often say that the universe is just the space-time that we guess was produced by the Big Bang, and that must have a boundary. As for beyond this universe, it is definitely infinite, and you can understand that there are countless universes outside of the universe. ”

Qi Feiyang said with a smile: "I think it's best not to think about this problem, even if you want to break your head, you can't figure it out, and you will go crazy if you think that you can't do it in the end." As long as there is matter, it is already destined that the universe is infinite, and I think it is better to call it time and space directly, which is easier to understand. ”

Professor Tan looked at Qi Feiyang with approving gaze and said, "You are right, time and space are the definition of nothingness. I can't imagine that you little guy is quite talented, it's a waste to be a village doctor, why don't you resign and come here, I can accept you as my doctoral student, with your talent, you will definitely be able to train you to become the next Einstein in less than ten years. ”

"I can't help this, I didn't get good grades in physics when I was studying, but I don't know anything about astrophysics, and I'm still a little self-aware in this regard."

Professor Tan persuaded hard for a long time, and seeing that Qi Feiyang was completely unmoved, he said regretfully: "It's a pity, it's a pity that a good seedling, if Einstein had knowledge, he would definitely be very disappointed, alas...!" ”

Later, Professor Tan told them a lot about the universe, including the question of whether there are parallel universes, saying that parallel universes may exist in the same space system, but not in the same time system as the original universe, so we can't see it.

Qi Feiyang listened, thinking that the timeline of the spirit world is also different from the earth, and he heard the fire phoenix say that the Qingxu Daojun moved the spirit world from other galaxies to the galaxy at that time, and they can usually enter and exit the spirit world in an instant, so the spirit world must not be far from the earth, but no one has ever discovered this planet, this is very strange, I don't know if the spirit world belongs to a parallel universe.

While talking, they had unconsciously arrived at the gate of the park, Qi Feiyang and Yang Bishan said goodbye to Professor Tan and found a restaurant nearby to eat.

Qi Feiyang ordered a Hehua fish, lemon duck and a green vegetable, Yang Bishan played with her mobile phone for a while, and said, "Feiyang, we may have been deceived!" ”

"What's the matter, who is so bold and dares to deceive us!"

"It's Professor Tan! I just checked on the Internet, and that university didn't have a teacher named Ai Yinsi at all, and I searched again, do you know what the result is? This Professor Ai is a mentally ill person, known as Ai Maniac, because he tells people those cosmic truths all day long, and he talks about Einstein's theory of relativity, so some people jokingly call him Professor Tan! ”

"Damn...... But I don't think this Ai madman is really crazy, I think his body is completely fine, and he speaks very logically, maybe he is too focused and fascinated by studying the origin of the universe, so he looks like a madman. ”

"That's right, I think a lot of what he said makes sense!"

Qi Feiyang said with a smile: "Geniuses are always lonely, they are mavericks, their words and deeds are different from ordinary people, because it is difficult to find the same kind around them, so they are often considered crazy." Regardless of whether what he said makes sense or not, eating enough is the last word, let's eat first! ”

After dinner, the two went to Nanhu Park, walked leisurely in the park, and boated in the lake, so as to experience the romance of a couple in love.

Qi Feiyang and Yang Bishan made an appointment with their respective college classmates to have dinner together in the evening, and the location was set by Qi Feiyang's classmate Qin Hao, and Qi Feiyang followed the navigation and walked for more than 20 minutes before arriving at the hotel called Dream Taoyuan.

Qin Hao was already waiting for them at the door of the hotel, and when he saw Qi Feiyang driving a Lamborghini over, he said with a smile: "Zhong Tao said that you kid is developed, sure enough!" ”

Qi Feiyang introduced Yang Bishan to him, and Qin Hao said: "Who in our class doesn't know your little sheep, so I need your introduction!" ”

Qin Hao is a native of Yongcheng, working in the Ninth People's Hospital of Yongcheng, although the relationship with Qi Feiyang was not very close when he was in school, he got along well, plus he and Zhong Tao are fellow villagers, and often go to their dormitory to play with Zhong Tao, so they also know some about the relationship between Qi Feiyang and Yang Bishan.

Qi Feiyang also invited Qin Hao to attend the wedding at that time, but Qin Hao happened to have something at home, so he called him to say sorry and sent him a WeChat red envelope.

Qin Hao led them to a small private room on the second floor and asked for a pot of Luo Han Guo tea, Qin Hao briefly talked about his work and asked: "Feiyang, there is something I don't understand, you are from a family of traditional Chinese medicine, why did you choose to study in a medical university?" ”

"Actually, it's nothing, I just think that Chinese and Western medicine have their own strengths and weaknesses, and I hope that the two medical fields can learn from each other's strengths."

"I completely agree with you, we study modern medicine, and we naturally know a lot about Western medicine, and after coming out to work, I feel more and more that Western medicine is indeed a little bit difficult to start with some chronic diseases."

Qi Feiyang said: "Modern medicine is to find out the cause after discovering the problem, and then try to solve the problem, following the cause and effect relationship, and the logical relationship is very rigorous. Although TCM also follows the relationship between cause and effect, compared with Western medicine to analyze and solve problems on a case-by-case basis, TCM looks at the problem from a more holistic perspective and finds the cause from the root, including the relationship between the human body itself and man and nature, so some TCM theories, such as the theory of yin and yang and the five elements, seem to be a bit mysterious, but they do have their own uniqueness. If the two can be organically combined and learn from each other's strengths, it is very beneficial to improve the level of medicine. ”

"That's right, so I've been reading some Chinese medicine classics during this time, and I feel that many things passed down by my ancestors are still very reasonable, but there are also a lot of dross in them, and I can't accept them all."

"That is inevitable, the ancients' understanding of the human body and nature is only the simplest superficial things, and it is impossible for nature to slowly discover the essence of things through modern technology as it is now."

The two were chatting happily, and at this time, two of Yang Bishan's classmates came, one was Xie Xiaowan, an undergraduate classmate, who worked in a state-owned enterprise, and the other was Mo Dingqiang, a graduate student, who was a white-collar worker in a foreign company.

Yang Bishan introduced them to Qi Feiyang, Xie Xiaowan was a little surprised when she heard that Qi Feiyang was just a village doctor, and she didn't understand how Yang Bishan could fall in love with him with such good conditions.

When she heard that Qin Hao was a doctor in the city's third hospital, Xie Xiaowan's attitude became much more enthusiastic, and she took the initiative to chat with him, left a phone number and added WeChat to each other, and then chatted with Yang Bishan about college and work.

And Mo Dingqiang looked very self-contained, shook hands with Qi Feiyang and Qin Hao, and said enthusiastically: "Welcome two to Guidi for their honeymoon, there are many interesting places here, such as Detian Waterfall, Shanshui City, Longji Terraces, etc., which are very distinctive and worth visiting." ”

"Thank you, Brother Mo, we also have this plan, we are going to see the waterfall tomorrow, and then go to Liucheng and Shanshui City."

At this time, the waiter served the food, Qin Hao hurriedly beckoned everyone to the table, he opened a bottle of XO he brought, brought wine to everyone, raised his glass and said: "I didn't go to Lingnan to attend Feiyang and Bishan's wedding for some reason, just take this opportunity to congratulate the two newlyweds on a happy marriage and give birth to a noble son early!" ”

This restaurant is a pure Guidi flavor, also belongs to the Lingnan cuisine series, and integrates Hunan and Guizhou flavors, Qin Hao ordered grilled fish, lemon duck, crispy button pork, black bean pork knuckle pot, fried banana heart and other local specialties.

Qi Feiyang and Yang Bishan also toasted to them, Qi Feiyang said: "Thank you for the kindness of several students, after graduation, everyone is different, and today we have the opportunity to meet in the beautiful Yongcheng, I and Bishan toast all the students, I wish you good health and a smooth career!" ”

After Xie Xiaowan drank the wine, she talked more and asked: "Bi Shan, with your conditions, you can find a good job in the provincial capital after graduation, with an annual salary of at least more than 100,000 yuan, why do you want to go back to your hometown, is it just for love?" But feelings can't be eaten! ”

Yang Bishan said with a smile: "No way, Feiyang has to go home to be a village doctor, I have to marry a chicken and follow him back to the countryside, as for the income, I think it doesn't matter if it's more or less, it's enough." ”

"That's not the same, if you think about it, if you are in a provincial capital, the annual income is higher than that of a small city for several years, and the gap will get wider and wider after three or five years."

Qin Hao saw Xie Xiaowan's vigorous sarcasm at Qi Feiyang, and felt funny in his heart, if she knew that Qi Feiyang was a rich man, she wouldn't be shocked to drop her jaw!

However, in this fetishistic society, this idea is normal, after all, everyone wants to live a more comfortable life.

Mo Dingqiang felt that it was very inappropriate to say these words on this occasion, so he deliberately diverted the topic, raised his glass and said: "We come from different places, we are destined to study together, and today we are destined to meet in Yongcheng, this is all fate, let's have a toast to the fate between us!" ”

Qin Hao also said: "Yes, yes, there are more than a billion people in the country, we can all become classmates in the vast sea of people, what a rare fate, come on, cheers to our fate!" ”

Qi Feiyang said with a smile: "If a few students go to Lingnan in the future, welcome to Songshan to play, although Songshan is not a big place, but the environment is good, and the transportation is convenient." ”
