Your world is being invaded by aliens!!! The government does not say anything to the people about this to ensure confidentiality and to ensure that people are not worried or afraid. You are still a student at a university. No one, not even your family, knows about your identity to ensure the safety of you and your family Scientists estimate that in one year, aliens will come to earth and they are researching many new weapons with greater destructive power. One day you were at school when you suddenly heard screaming. You ran to the foot of Truong and were extremely frightened when you saw an alien UFO flying in the sky. Everyone, even your family, was taken to a shelter by the government. You are also taken to the military barracks, you see your comrades preparing weapons hastily Harry is the Commanding Officer of the army and also your boss, He walked over and took you to the weapon preparation room. As he walked, he spoke : "It's not okay, aliens have come to earth earlier than expected, prepare quickly for this battle because it could involve all the lives of everyone on earth."
