How is it that low specific heat materials don’t break physics

Wouldn’t a low specific heat material break thermodynamics. As I could theoretically use just a few joules to increase a lot it’s temperature

For example a compound with a specific heat(c) of 10⁻¹⁰ would generate approximately 10⁷ heat difference with just 1J(T=1J/1000g*10⁻¹⁰) , an extreme case but shows my point. And with this difference in heat I could probably generate a lot of energy with something like a turbine, therefore breaking thermodynamics as I could generate more energy than input in the system.

And I know there are some technologies like OTEC or geothermal Rankine cycles that use this lower specific heat to their advantage, what is it that I miss understood or missed out?
