Yun Que explained:
"Later I found out that as my cultivation increases, the sound of firecrackers must become louder and louder in order to calm my mind and relieve my mental fatigue. At my current realm, ordinary firecrackers are completely useless; it requires a volley of ten thousand cannons sounding together. If His Majesty is reluctant to part with this Martial God Cannon, he can also have someone haul ten thousand regular cannons over, and I can just listen to the bangs here in the Hall of Clearing the Mind."
Bai Longyou felt his nose twitch as if it were about to be twisted out of shape, and he instinctively rubbed the bridge of his nose.
If ten thousand cannons went off inside the Imperial Palace, you might get to listen to the bangs, but the Imperial Palace wouldn't exist anymore!
