The Angel of Time Travel Is Very Arrogant

On her way back to the city, she inexplicably came to a subway station that traveled through time and space. Here she met someone who entered this subway station inexplicably like her. The two of them traveled together to the Kingdom of Heaven period in the parallel world and started this difficult journey. The girl got an angel's space and continued to be her angel nurse. The boy got a monster-fighting system robot, which can not only fight monsters, but also make medicine. The two met in the medicine business in Heaven.
