As a Great Grandmaster who was utterly obsessed with martial arts, Lei Ting had an unparalleled pride and self-respect. To forcibly overturn Lei Ting's decision was to deny all his pride, and Chu Mo was certain that once he did so, Lei Ting would probably turn around and leave, never to appear before him again.
At this point, Chu Mo was faced with two choices.
One was to acknowledge the result of the competition, and from then on, he would no longer interfere in any matters concerning the Hua family in The Great Northwest.
If he truly did that, having let the Hua family of The Great Northwest go might incite a stronger sense of rebellion from the remaining two families. The Wei family from the southeast and the Mo family from the Magic Capital would probably resist with all their might, greatly impacting his future task of regaining control over the remaining two families.
