"They found life on Mars?" NASA experts watched the video eagerly.

    "I knew there must be life on Mars!" someone jumped up excitedly.

    "Life exists on Mars?" a group of experts at the Russian space agency stared at the screen.

    "This is definitely one of the great discoveries of Martian ecology!" in Europe, a group of people are watching Du Xingyu''s video.

    In the picture, Du Xingyu''s team members appear. First, Xu Lianqiu explained, "in yesterday''s sampling observation, we found an anaerobic bacterium, methanogens, in Martian soil."

    The video switches to the picture in the high-power electron microscope. Methanogens are exchanging materials.

    "After comparison, we found that the similarity between the methanogens on Mars and the methanogens on earth is more than 90 percent!" Xu Rui said in the video.

    "Can this explain that there are some connections between the origin of life on Mars and the earth?" Yao Feng and others appeared one by one, telling their discovery and inference on Mars.

    "There is life on Mars!" the audience was already boiling.

    "Niu PI, this discovery is too hanging!"

    "I suspect that humans migrated from Mars. Otherwise, why is the earth''s environment just stable after the harsh environment on Mars?"

    “66666！”

    "Mars has a real hammer of life! The speed of light transmits a wave!"

    Experts from various countries were also blown up by this news. Anaerobic bacteria were found on Mars, and they are more than 90% similar to the ancient micro organisms on earth!

    The significance of this representation makes everyone have to pay attention to it!

    Immediately after Du Xingyu released the video, NASA also announced the news: "China''s Mars mission team successfully found microorganisms in Martian soil!"

    This news was forwarded and published by countless media.

    People''s news: "Chinese astronauts found life on Mars!"

    Surging news: "absolutely heavy! Mars finds life!"

    Microblog hot search No. 1: "# China found microorganisms on Mars #"

    UC browser: "seven billion people on earth were shocked to see this!"

    Penguin news: "Martian life, Download Penguin news and watch the full video."

    Only: "what do you think of the discovery of methanogens on Mars by Du Xingyu and others?"

    QianDu: "there is life on Mars. What''s going on? Everyone must know that China''s Mars mission team went to Mars for scientific research, but what''s going on when Mars found life? Let''s take you through it."

    "There is life on Mars. In fact, the scientific research team found microorganisms on Mars. You may be surprised why there is life on Mars? But the fact is that, Xiaobian is also very surprised."

    "This is about the emergence of life on Mars. What do you think? Welcome to tell Xiaobian in the comment area to discuss together!"

    Netizen comments: "one opening is the old marketing number!"

    "Reported!"

    "What water!"

    A video by Du Xingyu makes the earth noisy. The overwhelming news is about the discovery of microorganisms on Mars, and all kinds of people jump out and talk.

    On the Internet, someone immediately stood up and claimed that they were the descendants of Martians, and experts came out to analyze the possible existence of Martian intelligent life. A group of star netizens also used this topic to show their legs and figure, although we don''t understand what it has to do with the discovery of microorganisms on Mars.

    ……

    Du Xingyu has no mind to pay attention to the disturbance and noise on the earth. He is thinking about a question. If there were intelligent life on Mars, were they destroyed by space-time annihilation bombs 3.9 billion years ago?

    Or are earthmen Martians?

    The technology simulator can''t give Du Xingyu more information. He needs to find evidence to speculate.

    "The matter of Martians should be put aside first and let those experts ponder and toss!" Du Xingyu thought, "or think about how to deal with the asteroid impact."

    "Crisis comes from Neptune!" this is the greatest crisis prediction after the technology simulator collects information.

    Neptune is the farthest planet from the sun among the eight planets in the solar system. The volume ranks fourth in the solar system and the mass is 17 times that of the earth.

    "It''s Neptune again!" 3.9 billion years ago, it was because Neptune''s gravity changed the orbit of asteroids and meteorites in the Kuiper belt when it passed through the Kuiper belt, which led to the birth of Martian meteorite natural disaster.

    This time, it will bring disaster to the earth!

    "We should closely observe the orbit direction of Neptune..." Du Xingyu felt a little powerless when he thought of this.

    At present, mankind''s ability to observe the Kuiper belt is very limited. Asteroids with a diameter of tens of kilometers must be at least the distance from the orbit of Neptune before they can observe it.

    The problem that Du Xingyu still has to solve is how to "solve" the asteroid or change its orbit.

    On Mars, Du Xingyu stayed for another month to complete some scientific research tasks.

    Soon it will be the day to return. He, Xu Lianqiu, Shen Yan and Xu Rui will return to earth, and the other six will continue to stay on Mars to build bases and research. A year later, the spacecraft will travel to Mars again to bring the members of the shift.

    "Everybody, take care!" Du Xingyu saluted the team members who stayed on Mars on the Mars spacecraft Yinghuo.

    "Captain, let them give more food next time! I''ll throw up if I eat cans and potatoes every day!" Su Peng shouted in the messenger.

    "See you on earth!" the Mars fluorescer spacecraft started again. It easily rushed out of Mars''s thin atmosphere and returned to earth.

    Because the distance between Mars and the earth has increased in recent months, it took Du Xingyu and others 40 days to return to the earth this time.

    On the ground, a large number of people have been waiting for their return.

    Du Xingyu has experienced this scene once. Leaders shake hands, reporters interview, family meet, relatives and friends greet, physical examination and so on

    The outside world has countless questions to ask them about space navigation, Martian environment, Martian life and so on. Everyone''s time is full.

    However, in addition to the necessary work handover and short meeting with parents and friends, Du Xingyu postponed all interviews and activities on the grounds of physical rest.

    The media and people all over the country are celebrating the complete success of the Mars mission and the major discovery of Martian microorganisms, but Du Xingyu is considering how to deal with an asteroid!

    "If the diameter of this asteroid is too large, then I have to choose to escape from the earth." Du Xingyu was thinking, "if it is an asteroid with the same diameter as the extinction of dinosaurs, human civilization still has a chance, what should I do?"

    Of course, we can''t give up the earth unless we have to.

    "We must eliminate the hidden danger outside the earth''s orbit! Otherwise, it will be more difficult to deal with because it is attracted by the earth''s gravity. Moreover, asteroid debris will hit the earth, that is, meteorite rain, which is unbearable for human civilization..."

    "So the first idea is to solve it outside the earth! At present, Mars can be used as a forward position!"
