Xiaoming is playing a new type of flight chess on the computer. If the die shows a black number, it means to move backward; if it shows a red number, it means to move forward (for example: black 2 means to move back 2 steps, red 3 means to move forward 3 steps). He rolled the die 5 times, resulting in black 5, red 4, red 2, black 3, and red 1. After moving according to these rolls, he found himself on the 6th square. On which square was he before he rolled the die for the first time?
