The Sample

The protagonist, Cat, witnesses his colleague discover eternal DNA in 2022. He is jealous of the janitor who can achieve such great success, so he invents the time machine and travels to 2070 to steal the DNA sample. He tries to cross over three times, but the first two are unsuccessful when he enters the DNA lab. On his third attempt, he successfully enters the door of the DNA lab in 2070. Unfortunately, he is caught by security. He decides to send the DNA to the past through the time machine, and the DNA sample is teleported to a janitor who works in his company in 2022.
