At present, there is a worldwide effort to use cold atoms to simulate strongly correlated quantum many-body systems. It is hoped that these "simulations" will provide solutions to many unsolved problems. However, the relevant energy scales in most of these experiments are so small that one has to go to entropy regimes far below those achievable today. Here, we present a general scheme to extract entropy directly from the region of interest. The late stage of this process is equivalent to a continuous "evaporation", and is able to combat intrinsic heating of the system. For illustration, we show how to cool a weak coupling BCS superfluid (with $T_{c}\sim 10^{-10}$K) to $10^{-11}$K with this simple procedure, with entropy per particle as low as $5\times 10^{-4}k_{B}$ in the superfluid region.
