Phase waves were something most people found difficult to understand. Those who could cultivate the Da Xiang Xiangbo Gong were usually experts who had formed a Core and possessed some insight into the path of particle-wave duality. But to Wang Qi, phase waves were a concept he had thoroughly understood in his previous life.
On Earth, phase waves were called matter waves, or de Broglie waves. Based on particle-wave duality and Special Relativity, physicist Victor de Broglie proposed this concept: every macroscopic particle possessed a frequency or wavelength corresponding to its energy, and particle-wave duality applied equally to the realm of macroscopic particles.
The phase waves Wang Qi emitted with every gesture could essentially be regarded as a kind of matter. This wave-like matter was perfect for use as a sword blade, because its sharpness approached what Earth called "ideal conditions." It was simply impossible to forge a thinner edge.
When combined with mana, these wave blades surpassed even a Sword Cultivator's Sword Qi. Cutting iron like mud was nothing out of the ordinary. This was also what the Free and Unfettered Cultivator De Buyi had relied on when he shattered the Golden Sword Demon King with his bare hands.
At the instant of their collision, Wang Qi had concentrated all the phase waves in his body at his shoulder and slammed hard into Du Bin's flying sword. Phase waves were incomparably sharp; they had long since pierced the flying sword's surface. A thread of phase wave invaded the sword and directly cleaved apart one of the spell sigils inside it. With the spell sigil incomplete, its functions were incomplete as well, so Du Bin naturally found it difficult to recall it.
Yet Wang Qi chose that moment to toss out a light, mocking remark. "Little Du, haven't you practiced
