Super Seminary: Shadow of Kamigawa

My name is Tai'an. I met a scumbag who was committing murder. I went up to do it, and then I was stabbed three times. I thought I was kneeling. God damn knew that there was an old man who called himself Dinghei and said that I was from the Kamigawa civilization. I stood up again, and the scumbag killed me. The police came later. , I inexplicably became a hero who protected the people. Later, a group of men in black found me and told me that I was a warrior with super genes. They asked me to enter a place that sounded like a pyramid scheme den to study and then become a soldier and fight with the chrysanthemum that suddenly appeared in the sky three months ago! God, what the hell is this? Please spare me!
