How do I collect these materials?

Slurp! Looking at the picture, you have enough of the bottom ingredients, but you need to synthesize the mid-stage water drop ingredients first to create the higher-tier research stones. Hmm! If clicking doesn't do anything, double-check the facility level or prerequisite research conditions for crafting those ingredients. As the saying goes, 'A strong foundation prevents the castle from collapsing,' so it's important to take things step by step.
