Spiritual Pets Mobilization

A man has worked hard to learn all kinds of knowledge since he was a child, hoping that one day he would fight poetry, get slapped in the face, pick up secret books, take pills, and open a harem after traveling through time. One day he really traveled through time, and then found that what he had learned before was useless and he had traveled to a strange place. There's no poetry fight here, it's funny.
