The Law of Brutal Rebirth was not merely a Law of healing.
Its deepest concept was transformation through adversity. The closer one approached destruction, the greater the rebirth. The closer one approached death, the greater the return.
Eventually, that understanding gave birth to Beginning's Domain which also happened to be a very rare type of Domain. A Trial Domain.
Unlike most domains, Beginning's did not necessarily require a hidden layer in the second layer of the void to manifest. It could become a world, but it did not have to. More importantly, it did not care about physical bodies. What mattered were souls and essence.
As long as Beginning possessed even the slightest advantage over an opponent, he could forcibly drag their soul and essence into his Trial Domain.
The Trial Domain was essentially a death battle. A brutal contest between two souls. The winner devoured. The loser was devoured. Simple. Cruel. Absolute.
