In the sports school warehouse late at night, the iron door creaked, as if it had been pushed open by the wind, or like an old dream being gently pushed aside by someone.
Lu Mingming squatted in the corner, his fingertips brushing against a dusty cardboard box. The dust floated like fine snow in the moonlight. He didn't turn on the light, and only used the dim light seeping in from the window to lift up the yellowed kraft paper layer by layer. Stacked in cardboard boxes are training logs, broken wristbands, faded number plates - all forgotten relics of the youth academy. He wasn't supposed to be here. He should have forgotten this place long ago.
But he came anyway.
His fingers rested on a thin book. The cover is handwritten in Song font: "Youth Training Camp·2013·Internal reference only." The handwriting is neat, but with the unique stubbornness of a boy. Every stroke seems to be competing with the world.
He held his breath and turned to the first page.
It is the "Dynamic Center of Gravity Adjustment Method" - he spent a full three months that year, drew more than 300 action breakdown diagrams, and tested repeatedly, just to enable each young team member to use minimal muscle consumption and maintain maximum stability when changing direction at high speed. He remembers that when he handed this method to his coach, he only glanced at it and threw it into a drawer: "It's too complicated and young people can't practice it thoroughly. We use a standard template."
He didn't argue. He knew it was useless to argue.
