How does the Shaohai Holy Land in the legend of zelda get through that door? I just can't paint for a long time.

The prophet gives you a letter with a sequence prompt and a mark on the map.

Then, in the order of 123, they came to the island they marked.

The first island looked up, and there was a red gem at the top of the stone pillar. Then the whistle sounded and the red gem was activated to blue.

Next, I came to the second island. The red gem is in the north of the island, and the whistle is activated.

Finally, come to the third place, activate the last red gem, and there will be a passage to the bottom of the sea.
