The Revenge Shadow Rider held a status in the hearts of the Atlan Federation far beyond just being a Saudi ace. Regarding this battle, he had not been supportive originally, but if the challenge came at this time, he fully supported it since it was clearly a fight that the Revenge Shadow Rider could not participate in. This would allow Saudi to elaborate greatly on subsequent issues.
However, one should never say never, because anything could happen with the miraculous Shadow Rider. If this guy really showed up, there was no choice but to hope for good luck for Saudi. Kexiao was well aware that this was a tactic by the Military Department to limit him. At the start of this political bet, his chances of winning were destined to be slim to none.
