"Why Qing and Chi?"
Gu Jianlin couldn't help but ask.
"At that time, we didn't know. We just followed the ancient prophecy and found these two children, but only when they returned from the depths of space did we realize something."
Ji Zhou turned around and gave him a deep look, "Time difference."
Gu Jianlin was taken aback, then understood.
"Back then, Einstein hadn't been born, and the world didn't have the theory of relativity. We discovered through observation that the physical laws of the Outer Universe and the Inner Universe were different, but we overlooked the issue of time flow. When an object moves faster and faster, the time on it slows down. When it reaches the speed of light, time stops flowing. When it exceeds the speed of light, time reverses."
Ji Zhou calmly stated, "Theoretically, that's true. In our view, Qing and Chi spent a year in the deep space of the Universe, but in the time they perceived, a hundred years had passed."
