Phase Wave, in the eyes of most people, is something hard to understand. Those who managed to cultivate the Elephant Phase Wave Skill mostly had achieved a Golden Core and had some insights into the Particle Wave Dual Form path. But for Wang Qi, the concept of Phase Wave was something he had thoroughly understood in his previous life.
Phase Wave, called Material Wave or de Broglie Wave on Earth, was a concept proposed by the physicist Victor de Broglie. Based on the particle-wave duality and special relativity, he suggested: every macroscopic particle has a frequency or wavelength corresponding to its energy, and the particle-wave duality is also applicable to the macroscopic particle domain.
