Take the secret treasure of wood with the black phoenix girl as the head of the line. Hold down the CTRL key and move the mouse to find it, almost at the top of the stone pillar. Jump up and press the spacebar to start the plot.
The secret treasure of the earth is not the flash. It's a treasure chest that you can see after completing a little girl's quest and taking three incense sticks to the small temple. After you open it, it will trigger the plot.
