Baiyi knew that people felt they could easily ascertain the disparity between dragons and humans. This fact was because the power levels of different individuals always seemed very obvious at first glance. . However, there were some weaker dragons that were incapable of triumphing over a goat in battle; in this scenario, the goat of the Alpine Barbarians. If that was the case, then the power level of those mixed-blood dragon beasts, such as the lindworms, was better left to the imagination.
The reason why none of the Void Walkers would boast about slaying a dragon was because of how weak most dragons were. They could only boast if they managed to slay a dragon with the caliber of the Third Walker.
