He was a school bully and she was a straight A student. One day, she received a message that he wanted to meet her after school. She was very scared of being bullied, so she sought help from her teacher, who was also his father. Therefore, his father came to meet him after school with a broom on hands and beat him up.“You little brat! How dare you bully the top student in our class!

Stay far away from her!”...Years later, in her wedding dress, she said to her best friend, “My husband used to be a school bully.

The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

After the Grand Descent, a name that was given to the descending of the mountain, the Three Great Sages made their ways to Mystic Mountain where they learned to harvest what we now call magic, establishing the Mystic Cults and eighty-one sacred shrines to help aid mankind with the cult’s mystic powers against the eternal fight to the death with demons.
