The time-spacers correct possible changes in parallel time and space when they work, ensuring that parallel time and space are not chaotic between their respective fields. They have the power to travel through time and space, but they are also ordinary people. No one knows their names or even their existence.
Ah Jin went on a mission for the first time, but he chose... A ball of black energy? ? The spiritual power overflows in the parallel time and space, and then a mass of black energy is produced. The black energy is born between the heaven and the earth. It is unrestrained. It absorbs resentment and regards all living beings as trivial. As the power becomes stronger and unfettered, the impact on the parallel time and space becomes more and more powerful. They can only send timers to intervene to prevent it from continuing to grow. They meet A Jin who is on a mission for the first time. And can she still go home...
