One day in 2030, observatories around the world observed a meteorite that would hit the earth in 10 years. After countless complex calculations and deductions, it was found that nothing could change the outcome of the meteorite hitting the earth.
All countries in the world are uniting like never before, planning A, plan B, plan C... Preparing one by one. The purpose is to allow more people to survive.
(The story has two endings. One is that netizens hope that mankind survives. The other is to pave the way for another book I will come up with in the future. Humanity is completely destroyed!!)
