The Killer Who Controls the Shadow

My name is Xu Shaoling, I am thirty years old, and I am a Chinese teacher at No. 3 Middle School in Wuchuan City. I am not doing well, my salary is enough to buy groceries, and my days are as gray as the fog in this city. This poor place in Wuchuan is surrounded by fog all year round, the smell of burning coal is choking, and the streets are full of loan advertisements. But here, I picked up a pair of broken glasses and a broken cabinet, and somehow became a murderer. The glasses catch shadows, the cabinet turns into a clay figure, and if you poke the clay, the people outside will fall - evil, right? I tried it, and my hands shook like chaff and my heart beat like a drum, but it felt really good. This ability is not simple. I can't catch the shadow in the thick fog and darkness. Not to mention working in vain. Every time I use it, my own shadow is still a little shorter, as if someone has secretly cut off a piece of flesh. I'm not a good person, and I don't have any dreams of being a hero. I'm just a teacher. It's a big deal to scold students for their bad words. But when this thing is put in front of me, it looks like it's just trying to get me to do something. There is no shortage of corrupt officials and bullies in Kirigawa. I want to give it a try, but I am afraid that I will lose it - what is hidden behind these glasses that I cannot afford to offend? I'm not a hero, and I don't want to be a bad guy. I'm just a teacher. I usually scold students for their poor handwriting. But these glasses and cabinet were placed in front of me, as if they were tempting me to try and see if I could do something big. In Kirigawa, there are corrupt officials, bullies, and even more annoying guys. I occasionally wonder, what would happen if I caught their shadow? However, I am also afraid that this thing is not just a tool, but there is something hidden behind it that I cannot afford to mess with.
