Breaking the Rules: Psycho from Isshusenyin

I was a high school graduate. Because I received the admission notice from the "Modern Academy of Immortal Cultivation", I followed the instructions and went there. As a result, he was directly regarded as a mental patient and stayed there for three years. When he walked out of the desolate and abandoned yard, he came to a strange parallel world. Here, a strange story about rules will appear once a month. I unfortunately became the chosen one. But when the people from the Rules Investigation Bureau discovered that I was a psychopath who couldn't even read the rules, they decided to give up giving me "hints." However, my abnormal behavior shocked everyone, and they felt that I was the one who "understood" (broken) the rules best. From then on, in this strange world, there was a rule breaker (immortal cultivator) who came out of the mental hospital.
