Pokemon Silver Soul, on the way to the city of Platycodon, there is no flash and gravel in the dark cave. How can I get there? Heroes, help me! ! ! !

There is no main plot in the dark cave, so you can go directly to Platycodon without going. If you break the rock, you can talk to a fat man at No.36 Road on the left side of Platycodon grandiflorum. You can get a flash at the top of the trumpet bud tower above Platycodon grandiflorum, or you can buy it in a department store in Huang Jincheng.
