After Hydra finished shooting, he returned to the bonfire for preservation, and then came back from the waterfall on the left. You can see the golden crystal. It's strange to save my sister after a fight. Don't forget to buy the magic of shining light.

After the first waterfall that killed the serpent, the golden crystal man was killed to save the dark princess. Then the stones by the lake can summon shopping, then you can find the golden crystal, and then you can find the princess's suit. Then you have to wait until you get the king's utensils, unseal them and enter the library, where a crystal giant kills the broken necklace. This is the one who entered DLC and took the necklace to save the princess. That golden crystal has a time hole.

Jin Shuijing people sometimes don't show up, so they just find a bonfire to have a rest, or stroll around and come back. ...

After saving Xia's sister, the call sign of Daming Lake may not appear. The solution is as above. If it really doesn't work, quit the game and start again.
