"Boss, I am just an ordinary person, an ordinary person who has traveled through time, and even an antique who to you is the age of the earth more than a thousand years ago! Now that I suddenly appear in this science fiction world where spaceships are flying in the sky, it is already very stressful. What will happen if there is a cosmic war and an alien invasion? People will die! Just show your kindness and let me enjoy the future world peacefully and live this ordinary life." "No." "..." _(:3∠)_
