In this world, life in Heaven is far more comfortable than life on Earth.
My original parents in Heaven reached an agreement with my future earthly parents.
My heavenly parents said:
"Since you will be the ones to bring our child into this world, you must care for him well, educate him diligently, and nurture him thoroughly, so that he may become a god in the future. The Central Department of Heaven will also provide resources to support you and the child, ensuring your lives are more comfortable and smooth—until the child's trials begin."
