"The murderer's back!" Cao Song, the repeater student, exclaimed when he saw Uncle Zuo, who just yesterday, during basketball, had witnessed Uncle Zuo knife another "Uncle Zuo" to death!
Blood had congealed on his coat; Uncle Zuo looked insane. Underneath, he wore patient attire, while on the outside, a white lab coat, making him both doctor and patient.
Step by step, he walked to his seat and sat down, hanging his bloodstained backpack next to the desk. He didn't take out textbooks but instead placed a bloody knife on the desk.
The students didn't dare to approach Uncle Zuo; his desk mate, Xiong Ni, looked especially frightened.
While touching the tip of the knife, Uncle Zuo still muttered to himself, "This is a large-scale learned helplessness experiment. Pain and despair are uncontrollable; one never knows when they will come. But if we give up resistance, even if there's a chance to escape later, we'll miss it due to habit!"
