What is the animation of being sent to another world to give birth to a person?

The cartoon of being sent to another world to give birth to a person was born for me. Gong Jian Zhaigong (voiced by Ono Yuuki) is an ordinary male high school student in all aspects. Although the mouth is poisonous, my heart is full of justice. By chance, he traveled to a different world called Gulambania, where human beings were eroded by filth, and the only way to purify filth was to rely on the witches of the twelve constellations. Of course, witches are not enough. What can really drive away filth is actually the son of the stars born to rare people and witches, and Jiangong Zhaigong happens to be a rare person.
