Such consumption was a huge drain even for a strong cultivator with profound foundations like Yu Yiyao.
After all, every cultivator who had managed to enter the Myriad Laws Realm trials was exceptional. Each possessed unique Divine Abilities and was not so easily suppressed.
It should be noted that an incident like Wan Fayi's easy elimination of opponents at the very beginning was an anomaly. If it weren't for the fact that the supreme strong cultivator of the Path of Space had lost his edge and, more importantly, believed that Wan Fayi would spare him, thus not resisting with enough resolution and determination, Wan Fayi wouldn't have been able to kill with a single blow.
If the opponent had truly fought back desperately, even with a lesser Realm, Wan Fayi wouldn't have been able to eliminate them so easily.
