"Dad?" soon Hansen''s child, Chris, a professor of astrophysics at Oxford University, found Hansen and his letter.

    "How could it be?" Chris looked frightened at the contents of the letter.

    "No wonder my father has been sighing. No wonder he has so much pressure... It turns out that the death star is not only an asteroid, but also a kinetic energy weapon of aliens!"

    Chris''s world outlook was overturned. He felt the despair his father felt! If aliens really want to destroy humans, what will humans resist?

    In addition to fear, Chris felt incomparable anger: "the human Guardian alliance is cheating us. They knew it long ago, but they didn''t announce it!"

    He immediately began to work and published the news on the Internet, social media and news newspapers.

    "The death star is an alien civilization creation!"

    "It''s accelerating. It''s a kinetic weapon that will destroy mankind! The human Guardian alliance has concealed the news!"

    "Everything we do is futile. We should talk to aliens!"

    Chris was crazy and spread the news everywhere, but not many people believed it.

    The reason is very simple. There have been too many similar news since the emergence of death star. On the Internet, thousands or tens of thousands of conspiracy theories appear every day, including celebrities.

    Chris released Hansen''s last letter to the media and said: "my father knew the truth. He spent every day in suffering and torture!"

    Some people gradually believe what Chris said.

    Not only he, but also people all over the world began to stand up, agree with and support the news, and bring out all kinds of evidence.

    The human Guardian alliance naturally knows the news. This is not the first time.

    There is no absolutely airtight wall in the world. Many people know this. In addition to Hansen, there are even people in their working group who can''t bear the pressure, suffer from depression, or end their lives by themselves.

    "Do you want to continue to block the news?" there was a discussion within the alliance.

    If they want to block the news, they just need to announce that all this is rumors and false, and the people''s attention will soon shift.

    "We''ve tried to block the news, but this time it didn''t work well," said a member of the information management department.

    "The news can''t be blocked. The death star is close enough to the earth," someone said. "Civil telescopes can clearly observe it and naturally calculate its speed."

    "The day of announcement will come sooner or later!"

    "Wait another two months," said Du Xingyu. "When the space warship is completed, the news will be announced."

    "We should not only bring despair to everyone, but also hope to them."

    "Yes."

    ……

    For two months, the league has not confirmed the news of Chris''s disclosure. The recent astronomical observation data show that the speed of death star has indeed increased.

    This made more people begin to believe what Chris said, and others asked the alliance to give real information.

    There are many similar rumors in China.

    Although people are confused, the overall mood is relatively calm. Because most people have been used to all kinds of storms and speeches in recent years.

    The first year or two was really difficult, but after the promotion of controllable nuclear fusion technology, people''s quality of life began to improve significantly, and there were many fewer complaints.

    In the dock of Longgang space warship, the "Silver Wing" planetary space cruise ship is undergoing final test.

    All its ships and supporting equipment have been manufactured, equipped with the most advanced power system and weapon system on the planet, and the newly developed superconducting quantum computer is used as the data processor.

    "Report, the power system is tested and everything is normal!"

    "Report, the weapon system has been tested and everything is normal!"

    "Report, the detection system is finished and everything is normal!"

    "Report, the operating system detection is completed, and everything is normal!"

    ……

    In Du Xingyu''s earphone, the report sound of each testing group kept coming.

    "Report to the commander in chief, the inspection of the Yinyi space cruise ship is completed, please give instructions!" Hu Chun, the chief engineer, saluted and reported to Du Xingyu.

    "Members of each group, prepare to launch Yinyi for the first low altitude flight test!" Du Xingyu ordered.

    "Yes, pay attention to Yinyi, and prepare for the first atmospheric flight test!"

    "Yinyi received, ready to start the atmospheric flight mode!" Liang Tianrui, the first captain in a space military uniform, shouted.

    His instructions were communicated to the whole ship. All parts began to act.

    In the first simulation, Yinyi planned to conduct an atmospheric flight test on the sea, and did not intend to fly directly into space.

    As long as the test passes, the performance of the warship can be determined by more than 50%.

    In Longgang dock, a huge silvery white warship began to start.

    The jet port at the bottom of it emits thick white smoke, which is the continuous jet of hot gas, lifting the nearly 40000 ton space cruise ship.

    There was a deafening roar around. It was the sound of violent collision of the air!

    The upper space of Longgang dock is automatically opened, and the Yinyi is suspended in the air!

    "Flying!" next to Du Xingyu, stood military weapon experts from China and other countries. They looked at the scene excitedly.

    "The silver wing took off!" an old expert burst into tears. He didn''t expect to see his country''s first space warship take off in his lifetime!

    "Let''s go!" Liang Tianrui shouted.

    The propeller at the tail of the silver wing started, and a horizontal thrust was applied to it at the same time. The silver wing began to join and fly over the sea.

    In the pictures taken by the satellite, the silver wing is like a silver wing cutting through the sky, flying wantonly over the sea!

    No aircraft carrier is worth mentioning in front of it!

    This is the most advanced war machine in the world!

    This is a warship that can rush out of the atmosphere and fly to the deep space of the universe!

    This is the foundation for mankind to resist unknown threats!

    "Captain Liang Tianrui, please report the situation of the ship." Du Xingyu shouted in the ground command room.

    "Received." Liang Tianrui said, "at present, the power of the power unit is 10%, and the takeoff speed is 3000 meters. It has stopped taking off. The vertical speed is zero, and the horizontal speed is about to exceed the speed of sound. It is conducting a test flight over the Pacific Ocean. All ship groups are in good condition."

    "Good, continue to test and fly around the Pacific Ocean!" Du Xingyu said with satisfaction.

    The silver wing flew over the Pacific for ten hours before returning to the dock, which was not its port.

    The port of the silver wing should be in the near earth space port. After entering space, it will be parked in the space port to reduce the energy consumption to and from the atmosphere.

    Although there were some small accidents during these test flights, they were all within the acceptable range.

    The date when the silver wing was announced to the world and flew into space for official service is also close at hand.

    "Prepare to announce it." Du Xingyu knew that it was time to announce the truth to the world.

    The human Guardian Alliance announced that it would hold a world-wide press conference at the end of this month to release important news and important achievements.

    In this regard, there is constant speculation.

    "Are they finally going to admit it? The death star is the kinetic energy weapon of aliens!" Chris realized that the other party could no longer ignore the questions he raised.

    "The human Guardian alliance decided to respond publicly!" countless people saw the news.

    "What is the real situation of the star of death?"

    "Can we really resist such a crisis?"

    "I heard that those rich people have ordered spaceships to escape from the earth. What do we ordinary people do? Stay on the earth and die?"

    "Don''t believe rumors, don''t spread rumors!"

    "Du Xingyu hasn''t spoken out for a long time."

    Under Du Xingyu''s social media account, netizens have been asking and urging changes.

    Because he was busy with research and development, Du Xingyu didn''t update it for a long time.

    This time, he intends to disclose some information in advance to obtain some energy points and enhance people''s confidence.

    At this time, mobile intelligent devices with "holographic projection" screen have appeared in human society, and mobile phones are also one of them.

    The once popular short video has also been replaced by the new social software of holographic projection. One of the holographic projection social software called "floating light" has become the most popular social software.

    Moreover, it breaks through international restrictions. The content published above can be seen at home and abroad. It is a world-class new social software.

    Du Xingyu registered a new account on the floating light, and the ID is still "earth observation". This ID can be passed on the floating light software.

    When he registered, the software company called to confirm his identity.

    When he learned that it was Du Xingyu himself, the boss of the software company greeted him personally and immediately made the operation group ready. Once Du Xingyu released the latest holographic projection video, the operation group immediately began to promote it all over the world!

    Du Xingyu is now a celebrity concerned by the world. His entry into Fuguang is more important than any star or celebrity!

    Du Xingyu began to make his first video on the floating light. The name of the video is "how to make a space warship".

    Today''s artificial intelligence is very developed. Using intelligent technology, Du Xingyu can easily edit holographic projection video.

    He explained: "Hello everyone, this is earth observation. Now many people are wondering whether aliens are attacking the earth."

    "I don''t make a final conclusion here, but if so, what should we do? Or, what should we do against it?"

    "Space fleet is undoubtedly our best choice! So in the first video, I''ll teach you how to build a space warship."

    "Before manufacturing, we want to find out the types and functions of space warships. The most commonly used ones are cruise ships and battleships in space..."

    In holographic projection, a virtual design space warship model appears. These are one of the simulation schemes used by Du Xingyu. It looks full of a sense of science and technology and a sense of future.
