Knight Leader had merely kicked.
Even so, Kanzaki’s body of a Saint was blown away along with the guarding scabbard. While she was knocked back and lost her balance, Knight Leader sent his clenched fist into her gut.
A tremendous sound rang out.
Kanzaki’s body was blown back 10 meters without landing and she struck one of the guard carriages. The carriage was protected by a number of spiritual items, but it was still smashed to pieces from the impact and Kanzaki’s body slid along the ground after passing through it.
