Yang Xiaofei, who was nearly 50 years old, lost consciousness due to overwork in his middle age. When he went home to rest, he opened his eyes and returned to 1997, a parallel time and space - on the old desk in the third grade classroom, where he was awakened by a flying piece of chalk from the math teacher.
In the process of running around the playground in the face of corporal punishment, the [step exchange system] was bound, and the gears of fate began to reverse:
Number of steps = RMB, number of steps = physical fitness + number of steps = wisdom +
He ran wildly through the streets of the end of the century, measuring the boundaries of wealth and super power with his footsteps - binding the movement system and walking out of a different past.
