Make a Contract with a Mythical Beast

When I was born, I had a red Xuanwu birthmark on my body. My father was horrified when he saw it and sent me to my hometown in the countryside. 16 Years have passed, and I wanted to live my life in peace, but I never thought that on the night of my 16th birthday, I would awaken my supernatural powers and form a contract with a mythical beast. When I was 19 years old, I would become the eldest brother of the supernatural circle in Langya City. When I appeared in front of my father intact, my father was dumbfounded.
