The end of an era often means the opening of another era. The only constant is that the times will always belong to the vigorous young people.


    Era 4933, Zhang Yuan opened his eyes again from his dream and began his ninth waking period.


    "Get up, it''s time!"


    The white light, the small room full of security, is the same girl. It is still a cold little year. In this age, there is a familiar and reliable partner, and the sense of security is still very sufficient.


    Recalling that he didn''t have Lin Xuanxuan''s company last year, Zhang Yuan couldn''t help whispering, "come here... Hold it."


    "Ah?" Suddenly hearing this sentence, Lin Xuanxuan felt sour and her eyes were a little wet.


    The fool''s first sentence before was always "what happened in the spaceship..."


    "... not here. There are others."


    Then, Zhang Yuan really asked the same sentence: "Oh... So, what happened in the spaceship?"


    "I knew you would ask!" Lin Xuanxuan rubbed her eyes, smiled and said, "everything is normal. Don''t worry."


    "Several minor accidents occurred, but generally speaking, the fault tolerance rate is within the allowable range. You guess, have we met aliens again in these hundreds of years? "


    "Aliens, there should be no more."


    Probably because of the shift arrangement, the girl always woke up half a month earlier than him.


    "Has elder martial brother Zhao been upgraded to captain?" Zhang Yuan asked again.


    "Yes, you are already the captain''s junior brother. Congratulations on your promotion."


    Zhang Yuan seemed to think of something. He was not in a good mood. He ignored her joke and sighed, "lend me your mobile phone... I want to check something."


    "Don''t play too long." Lin Xuanxuan seems to know why Zhang Yuan is not very happy and hands him his mobile phone.


    The original "Warwick 888" mobile phone brought from the earth has long been broken. It has been replaced by a simple black-and-white screen elderly machine. Of course, there is no need to play games and other things.


    Most of the electronic products brought from the earth have been damaged for so many years. Even the various military chips in the spacecraft can''t hold up. They have been replaced for several crops.


    Zhang Yuan opened his personal mailbox and found that it was full of mail, including a large number of government work reports and various captain logs, which described in detail what accidents occurred in which era.


    Then, in these emails, Zhang Yuan found the obituary of academician Ding and other leaders of the previous generation.


    Academician Ding did not explain anything more before his death.


    This series of obituaries gave him a faint sense of melancholy. Perhaps, this parting experience is more, it is not so difficult to accept


    ……


    In the following time, after discharge, Zhang Yuan was significantly busier than before. He is already a level 19 post. As one of the top leaders of the spacecraft force, he needs to make overall arrangements for the current sober personnel to maintain the spacecraft again and again.


    After all, the earth time is a 2700 year old spacecraft. Two thousand seven hundred years, not a hundred years. The passage of time has multiplied the probability of various errors. They can no longer boast and fart at work, steal laziness, read the news and play games as before.


    The closer you get to your destination, the more you can''t take it lightly. If there is any accident due to his negligence, Zhang Yuan will never forgive himself all his life.


    ……


    On this day, Zhang Yuanzheng led several correspondents to the Observatory for routine inspection.


    This is already a routine thing.


    Various communication devices in the observatory can receive electromagnetic signals from all over the universe from time to time.


    Most of these electromagnetic signals are random codes sent by stars and neutron stars. But there is also a very small possibility that it is a signal sent by earth civilization or alien civilization.


    Of course, because the probability is negligible, several people are also in a relaxed mood, just as a routine examination.


    "The next time you wake up, you''ll reach your new home planet!"


    "Yes, I''m really looking forward to it. 3000 years have passed... I really want to write this journey into a novel."


    "How about crowdfunding to write a novel?"


    Listening to the discussion of his companions, Zhang Yuan couldn''t help chatting: "after all these years, I don''t know how the earth civilization has developed? Have you got rid of the valley of mediocrity... "


    Another person also answered, "Captain Zhang, it''s very difficult. Once a trough occurs, it is unlikely to break free. We are 18 light-years away from the solar system. Even if someone has a whim and wants to communicate with us, they may not be able to find our exact location. If only someone could send a signal like Professor Edin. "


    "Hey, I don''t know how much it will cost to launch high-power electromagnetic waves. It''s amazing to be able to transfer a few bytes at this distance. "


    Observing the solar system at this position, you will find that the sun has become a dim star. Planets such as earth, mercury and Venus can no longer be observed directly. These planets can only be observed indirectly through an astronomical phenomenon called "Ling", or light color method【 1】


    At a distance of 18 light-years, even a huge sphere such as the earth is beyond reach. Without an accurate position, it is impossible for earth civilization to find the specific location of the spacecraft. It is impossible for the spacecraft to receive a string of electromagnetic waves indiscriminately.


    "Eh!"


    A colleague suddenly said, "this electromagnetic wave seems to have a little logical relationship, but there are too many errors. It may be an accident."


    "Write it down first. Any news from the earth is good. Even if there is no result, there is no loss, not...... "


    Zhang Yuan turned to another correspondent: "did you find any hardware problems?"


    "Not yet, but the computing speed of this computer is getting slower and slower."


    "If you can repair it, try to repair it. If you can''t repair it, you can only replace the parts... How many parts do we have..."


    The voice didn''t fall. Suddenly, Zhang Yuan was stunned.


    He raised his head, narrowed his eyes, and remained stunned after a long time.


    The pupil contracted slightly, as if I couldn''t believe it!


    In his perspective, a large amount of light shines from the glass cover above his head... A huge sun appears in the dim cosmic starry sky!


    Did something explode?!


    The other two correspondents also stared at the large glass cover at the observatory and didn''t react for a moment and a half.


    The light continues and becomes more and more intense. It shines the originally dark Observatory like day, and even makes people feel like basking in the sun in summer.


    Zhang Yuan''s heart began to beat wildly, and a cold sweat came out of his back.


    Pop!


    One electronic screen suddenly went out, and several other screens began to shake wildly.


    Zhang Yuan continuously pressed several buttons in front of the computer, which analyzed the source of the strong light.


    One


    Supernova!


    More than 7000 light-years away, the already unstable seamount 2, that is, the ship base η Star, it''s exploding!


    At this moment, the brightness of this supernova exceeds the sum of hundreds of billions of stars in the Milky way and becomes the ultimate bright spot in the universe!
