How did the Feng Shui mantra, master key and main explosive bag passed by Q in the Spring and Autumn Period get the fragments of exterior decoration, transformation card and back decoration?

Take Feng Shui charm, master key and blasting bag, and go to Zhou Zhou to find' Xuxing'. Through him, you can enter the Feng Shui treasure house and look for boxes or explosives in the Feng Shui treasure house. If the box is opened, the explosive will explode the explosive. Feng shui is very troublesome. If you use Feng Shui, he will give you a general direction to dig for treasure. Generally speaking, if the hint is far away, it means that the position 30 coordinates away from the treasure you want to dig is of course in the direction of his hint. If the prompt is close, it means that the 1 coordinate is far.
