Xu Lixing felt a headache when she saw this. "Dad, what are you looking at? I can't understand anything."
"In layman's terms, it's theoretical knowledge about spacetime wormholes," Xu Jingming introduced.
"That I know." Xu Lixing nodded. "Spaceships that truly travel long distances in the universe travel through wormholes. Through a wormhole, one can arrive in a distant spacetime in an extremely short period of time. However, I don't understand any of the formulas you're looking at, Dad."
"These are all formulas used in spacetime folding," Xu Jingming introduced. "This formula is still very simple. It's like when a wave is raised, the waves vary in amplitude…"
