Do you remember where Su Bingtian first broke 9.91? At that time, there was an Italian young player who followed Su Bingtian across the key line, the result was 9.99 was the first Italian to break through 10 seconds, and he broke into the final of the World Championships in athletics to stand on the first track This scene is exactly the same as Su Bingtian's year Oh come on ^0^~
