"Professor Owen, I'm really glad to see you."
Harrison Clark blinked at the man in the white coat in front of him.
You couldn't blame him for easily revealing his emotions and seeming impatient.
Since arriving here, his mood had always been great.
Whenever he saw a familiar face still existing, he felt comfortable and lucky.
He had been changing history all along.
In his personal history, historical records were not a static book, but rather like Schrödinger's Cat, or as elusive as electrons moving around protons, making them unpredictable and uncertain.
Existing because he saw them.
Before his arrival in this timeline, before reconnecting, all history was nothingness.
It was only after he arrived here and personally lifted the lid that he could see whether the cat was dead or alive.
Using an exaggerated language, the time-traveling Harrison Clark created a universe every time he opened his eyes.
