Urban Divine Choice System

The air in the 14th class of Liberty School hung heavy with the scent of stale paper and nervous sweat. It was February 15th, the first mock exam of the third year, and for most, a grueling precursor to the college entrance examination. Yet, at the back, Yu Huazang lay sprawled across his desk, oblivious, caught in the deep embrace of sleep.

"Yu, wake up!" The physics teacher's voice, sharp and laced with practiced exasperation, cut through the quiet. He rapped his knuckles on Yu Huazang's desk. The boy stirred, slowly, then rubbed his eyes with a yawn that stretched his jaw.

"Teacher," Yu Huazang mumbled, a nod serving as his acknowledgment of wakefulness. The teacher snorted, a silent judgment on the boy's apparent laziness, before continuing his patrol. Yu Huazang knew what the teacher thought; he was just another lost cause in a class full of them. He was supposed to be answering a difficult physics question, but his mind was blank, clouded by exhaustion from his night job.

'Why don't I choose the shortest one or the longest one?' he mused, 'I choose D!'

Ding! Congratulations to the host for obtaining the God Level Choice System. The system is starting to initialize... 1%... 100%, binding successful!

What? System? He chose D and got a system? Yu Huazang frowned, convinced he was hallucinating. Nothing happened next, and a bitter smile touched his lips. A system? How could such a thing exist? He needed to focus on the exam.
