Yellow people cannot run under 10 seconds - this is the consensus of the world track and field community. When retired sprinter Su Chen was 30 years old, he discovered that his body had undergone "abnormal changes": the density of his muscle fibers began to increase, his reaction speed exceeded the limit, and he could even "predict" the sound of a gunshot at the start of a race. When he ran 9.85 Seconds on an unknown field field, the old coach of the national track and field team came to his door: "Do you know what this means? This is not your business alone."
