Xuanyuan Kai was a high-level grandmaster.
Leiya was a peak grandmaster.
However, Leiya had never learned any Ancient Martial Arts. Meanwhile, Xuanyuan Kai had learned the Xuanyuan family's "Taoism" from the "Esoteric Scripture of the Yellow Emperor."
While the book was very well known, Taoism was not part of that version of the book. It was also the only part of the book that contained a powerful training manual and was under the control of the Xuanyuan family.
This Ancient Martial Arts was considered to be part of the Internal Martial Arts. If successfully mastered, the inner chi they had would be twice the amount of those at the same level.
That was why despite Leiya being stronger than Xuanyuan Kai when they actually started fighting, they were on par with each other. Leiya was even at a disadvantage.
Boom!
