Stop! That's the School Beauty, Not Your Personal Pillow

['Sister' + remedial class + daily life + active and passive combination +...] (Rating has just started) Winter vacation is coming, and Jiang Chen, a poor student, is packed up by his parents and sent to the "Devil's Special Training Camp". Not only did he have to answer questions in a classroom that was 10 degrees below zero, he also had to accept 24-hour personal supervision from his aloof sister Su Qingge. I thought it was the beginning of hell, but Jiang Chen unexpectedly awakened the [anti-involution system]! As long as you mess around in the cram school, shock everyone, and tease your sister, you can get god-level skills and rewards. As a result, the style of the special training camp completely collapsed: In the math class, the famous teacher assigned the final question of the Mathematical Olympiad. Jiang Chen warmed his sister's hands under the desk and lazily reported the answer: "e-1, teacher, you missed a step by x." In English class, the returnee teacher mocked his accent. He responded with a pure London royal accent and corrected the other person's poor pronunciation of "sheet/shit", which made the other person die on the spot. In the physics class, the heating was turned off and the whole class froze. He dismantled an old radio and used his hands to create a "constant-heating handheld device". The super physics teacher was dumbfounded on the spot: "This is called physics changing the world!" All the top students collapsed: "Please stop showing off, we are here to fight, not to eat dog food!" Facing the shock of the whole class, Su Qingge bit her red lips and huddled under Jiang Chen's down jacket, blushing and heartbeating: "Jiang Chen, can you... Stop moving your hands?"
