In the secret realm of White Jade Capital, besides the twelve official towers, there are also numerous spacious, independently floating pavilions, providing temporary resting places for the trialists.
Of course, during the period of the grand competition, this is also where cultivators with energy to spare come to practice, compete, and exchange in private.
Just like the restrictions placed on the towers and squares, practicing sword techniques in these pavilions won't result in fatal injuries.
When a fatal injury is about to hit the target, the target will be "temporarily" isolated from the space, thus preventing an on-the-spot death.
As long as one doesn't die on the spot, with a cultivator's methods of Immortal Law, whether it be the physical damage from a Flying Sword Treasure or the Five Elements damage from Daoist Magic, they can be quickly treated and healed.
