LMD
LMD (Lungmen dollar) is a currency in Arknights.
Since the financial crisis, economic decline and political instability have stood in the way of trade. The widespread circulation of Lungmen Dollars has allowed for some recovery in the business world.
Usage
Because Terra has been rather unstable politically and financially for generations, many countries have chosen to adopt LMD, the sole currency of Lungmen, Yan, as the main international transaction where its rather unusual stability attracts foreign investors. As a result, LMD has achieved a similar status to the U.S. dollar on Earth that is widely accepted as the first and foremost legal tender in economic activities.
LMD is used for many things, such as leveling to promoting Operators, processing materials at the Workshop, and others.
Acquisition
Every operation awards LMD as well as 
EXP equal to 10 times of the 
Sanity spent when cleared, with the amount increased by 20% when it is cleared with 3 stars. As such, LMD will not be awarded from clearing operations that do not consume Sanity.
Operations listed in the table below awards more LMD than others (which is treated as a regular drop).

Trivia
| “ | "They didn't move that piano away, probably because it's too heavy. That alone is worth 1.8 million LMD. The li'l Miss was boasting to me about it, so try to be careful." "Take cover! Quick! Hide behind that piano!" "Oops." *piano gets broken to pieces* "They smashed through our cover! Relocate!" "1.8 million gone... just like that." | ” |
