[The traffic boat flew over the Jupiter naval port of the Asian Fleet. Zhang Beihai felt that he was flying above the mountains. Each mountain range was a parked space battleship. 】
[The military port is currently running on the dark side of Jupiter. Amidst the phosphorescence emitted by the planet's surface and the silver-white moonlight emitted by Europa above, these steel mountains are sleeping quietly. ]
[After a while, a dazzling self-light rose from the end of the mountain range, illuminating the parked fleet very clearly in an instant.]
[Zhang Beihai was visiting the military port. He knew that the current human beings were far from enough.]
["Zhang Beihai, political commissar Zhang!"]
[The old call sounded, and Zhang Beihai seemed to have returned to that afternoon, the afternoon when he and Wu Yue were discussing together before he thought much about it. ]
【"you are.?"】
[Zhang Beihai looked at the white-haired old man in front of him with confusion. He was at least sixty or seventy years old, but he felt a little familiar. 】
[Are they the descendants of an old friend? I can’t tell.]
【"I am Ding Yi!"】
[Although the old man is old, he is full of energy. Ding Yi looked at the middle-aged Zhang Beihai in front of him and reminded him with a smile: "Have you forgotten? Two hundred years ago, when you flew into space on a plane, we
Together!"]
[Zhang Beihai instantly recalled Ding Yi, but the difference between the other person’s appearance and the Ding Yi in his memory was really huge. 】
["Oops!" Ding Yi slapped his forehead and smiled self-deprecatingly. Then he took out a photo from his arms and handed it to Zhang Beihai: "Look at my brain. I'm old and my brain doesn't work well anymore."
.I hibernated late and ended hibernation earlier than you. I should be eighty-three this year."]
[When he saw the photo handed over by Ding Yi, Zhang Beihai confirmed that the other party was Ding Yi.]
【"Professor Ding!"】
["We are meeting old acquaintances in a foreign land." Ding Yi asked with a smile: "You came to the Jupiter base because of the Steel Seal Clan's affairs, right?"]
["That's right, humans are about to meet the three-body probe, and the fleet wants me to be the executive captain."]
[After listening to this, Ding Yi smiled even more happily.]
["It seems that we are going to the same place, but we are still a little different. Me, I want to contact the detector directly." Overjoyed to meet an old friend in a foreign country, Ding Yi held on to Zhang Beihai's hand tightly.
Shou: "It's really shameful to say that I took advantage of my age and went straight to teaching at the university after waking up from hibernation, taking care of doctoral students. The titles haven't changed yet."]
【"Are you going back to college again?"】
[Zhang Beihai asked.]
["Yes, I'm back again. I'm just a nerd and a pedant! I can't do anything well after leaving school, so I might as well go back to teaching honestly. Alas, I almost digressed. Anyway, I took care of a few students.
Thanks to my relationship with my parents and my status as a senior, I finally got one of the first opportunities to come into contact with the three-body detector."]
[Ding Yi said that he would not talk about his time in college here. He continued: "There are some words that these children today cannot listen to, but after all, I am a person who has spanned several centuries and I have seen more."]
[Ding Yi took Zhang Beihai and talked for a long time, just like an old man who had not seen an old friend for a long time but saw an old friend in the last moments of his life and couldn't help but express his inner emotions. ]
[Zhang Beihai listened quietly until a huge spaceship landed at the port. 】
[Ding Yi looked at the spaceship and asked: "Coming to pick you up?"]
["Yes." Looking at the steel peak in front of him, Zhang Beihai slowly read out its name: "Flagship of the Third Squadron of the Asian Fleet, Natural Selection."]
[An oval-shaped entrance appeared on the outer wall of the spacecraft. The traffic boat flew straight in and quickly slowed to a stop. A two-meter-tall young woman appeared with four stars shining on her shoulders. 】
[People who are two meters tall are not common on the earth, because too high a height requires higher blood pressure and a heavier burden. But in space where there is no gravity, you don’t have to worry about this problem no matter how tall you are.
】
[The other person is a typical representative of the new human race in space, and is much taller than the tall Zhang Beihai.]
["I am Dongfang Yanxu, the captain of the Natural Selection." Dongfang Yanxu saluted Zhang Beihai: "After receiving the order from my superiors, I came to pick you up."]
["Thank you, I have just come to this era, and there are many things I still need to ask you for advice."]
["Hehehehe." When Ding Yi saw this, he said: "The little girl is here to pick you up. Okay, I have to go and get ready. I can take a look at the Trisolaran technology before I die.
Look at what alien technology looks like, I, Ding Yi, have not lived in vain."]
["Political Commissar Zhang, I have to leave. If there is a chance, the two of us can have a drink."]
[Ding Yi couldn’t help but leave, Zhang Beihai said to Ding Yi: “Goodbye.”]
"Ding Yi has been hinting at Zhang Beihai before. He is probably worried that Zhang Beihai will be blinded by the development of human technology. Just like Hines."
"Xines lived a life worse than death before the drop of water came, because the impact of reality and ideological stamps on him was too great, and he did not recover until the human fleet was destroyed."
"If Zhang Beihai is really confused by the current technology of mankind, then the last flame of mankind may also be extinguished."
"Ding Yi has been talking about it for so long, and there is only one message that he has conveyed to Zhang Beihai, that is, human technology has not improved at all compared to two hundred years ago."
"Ding Yi, a university professor two hundred years ago, can still teach physics at the university two hundred years later, and he is still leading doctoral students. This can already explain his hint."
[Bruce Wayne: A doctorate recipient is already at the top level among humans.]
[Bruce Wayne: And Ding Yi can still enter the university and teach doctoral students at the same level as two hundred years ago. In other words, human beings' current technology has only reached the ceiling where the sophons blocked human technology two hundred years ago.
It can’t go any higher, it can only develop horizontally.]
[Bruce Wayne: But if this is the case, then what can humans do to resist the Trisolarans? 】
[Logan: I think the reason why Ding Yi took the initiative to observe the water droplets of the Trisolarans at close range was that in addition to the technological level of wanting to take a look at the Trisolarans before dying, he also had the desire to save one by one.
After all, if he goes up, the number of contacts will be reduced by one, and maybe one more person can be saved.】
