For three straight days, Dong Xuebin trained BACK.
He had always been especially sensitive to one-minute intervals, so when he suddenly rewound a non-integer number of seconds, his reactions were not as quick. BACK was his unrivaled trump card, and whether he could carry out his work smoothly in the future depended entirely on it. He had to familiarize himself with it as soon as possible and put his new ability to rewind any number of seconds into practice.

Dong Xuebin had been good at it as a child, playing smoothly enough that he usually would not make a mistake for two or three minutes.
But once BACK was added, the difficulty soared. Whether he rewound one second or two, it disrupted Dong Xuebin's rhythm. The scene changed abruptly, and the balls' positions suddenly shifted. At first, Dong Xuebin wasted dozens of one-second **BACK**s without managing to keep the game going. Gradually, though, he became more familiar with it, his reactions grew faster, and his success rate steadily rose.

Not long after entering his office, Hu Silian, the office director in police uniform, came in with a smile. "Director Dong, the second Director's Office Meeting of the month is at ten. I came to
