Everything in the world had energy, and energy was split into three main types, elemental, life and death. Spirits were part of death energy. Everyone had a soul, and even due to the New World's necromancy, death was not as permanent as on Earth.
However, that did not mean that the soul was as capable as it was before death. Based on the New World's laws, a soul would slowly be converted into life energy, which preserved the balance of the world.
That law existed within the New World, but a river containing that law did not exist on Earth or in the New World. After death, no one knew what happened to the soul. Song Junlang did not know, and Xiao Lin did not know, but after absorbing a portion of the power of law, Xiao Lin had a feeling that, even if he died at that moment, his soul would not lose consciousness as it normally would, nor would it turn into life energy.
