Chapter 618 - Chapter 579: Forever Together

To resurrect a dead person, three issues need to be addressed. The first is to bring back to life a body that has completely lost its life force. A living person's body has an ongoing flow of life force, which can be understood as a special kind of energy that gathers around the heart. When a person dies, the life force dissipates into the air because it loses containment. Therefore, Sun Wukong stored Sanzang's body in that mystic space in order to allow Ye Zi to reinfuse life force into Sanzang's body.
