When you see a wide line, it means I started explaining the past or present instead of the current time.

Once upon a time, there was an irresponsible scientist. This scientist was also smart and hard-working. One day, he decided to make a time machine. He spent years on it and finally succeeded. The first working time machine! He decided to test it himself instead of letting his team of 1,000 people help him. He started it and went in. It took 4 milliseconds for him to teleport to the past.

He got out through a mysterious door that was made entirely of amethyst. He didn’t care. He had teleported to the 3500s B.C. He decided to wreck the wheel right before it was invented. Luckily, the first wheel was right in front of him. He wrecked it. He tried to talk through his walkie-talkie, but there was no connection.

His whole building was gone. There were no cars. No big technological inventions. Nothing.

The scientist thought nothing had happened, but the entire world had become uncivilized and barbaric. He tried to teleport back to see what happened. He couldn’t. The time machine was gone, along with his entire lab.
