Every time you win a treasure, you will only increase your lucky value by 1 point. The lucky value is full on the 360th draw, and you can get the crystal directly after another draw.
In general, most players need to extract 36 1 time to extract the crystal. It takes nearly 20 thousand to draw 36 1. However, some European emperors often won the lottery more than 100 times or dozens of times.
