Qin Fangtian had very little understanding of Tao Rhyme. He hadn't even fully understood the Nine Swords, let alone Tao Rhyme. All he knew was that Zhong Yuxiao had been researching it. The latter had studied the Nine Swords, introducing fresh and new ideas, creating numerous sword skills and techniques, and even replicated a knock-off version of the Immortal Sword Intention. His qualifications for swordsmanship were astounding.
As for how far Zhong Yuxiao had gone on the path of Tao Rhyme and whether he had found any clues, Qin Fangtian was not quite sure.
He told Lu Bei that Tao Rhyme was something that came with luck, and it required strict comprehension and cultivation. Ordinary Kalpa Passers have no qualification to comprehend it. It needs to be like Zhong Yuxiao, who had undergone four Thunder Kalpa baptisms.
