To obtain Slime Concentrate, you need to find and kill Slimes over Level 60+. Upon eliminating these elemental enemies, they have a chance to drop Slime Secretions. Anything above Lvl 60+ also has a chance to drop Slime Condensate and Slime Secretions.
To get Slimes to become Lvl 60+, you need your World Level to become World Level 5 or higher. The most efficient WL to farm is WL 6, as enemies are between Level 64 and 84. This will give you the most consistent enemy Lvl past 60+. Anything below you will find them, but not as often.
To get to WL 6, you need to have completed the following.
- Be on World Level 5
- Be Adventure Rank 45
- Clear Ascension Quest 3
You can get Slime Concentrate from any of the Slime Family, no matter the Element or the size.
The quickest way to do this is to use the Waypoints, kill everything in sight, and then move on. It might take you a while to amass the numbers you need.
The two images below are where you can find Slimes in both Mondstadt and Liyue.
