Explosive! I Cultivate Immortality Through Thermodynamics

A science-minded young woman transmigrates to another world and finds herself with a handsome man in dire straits, whose cultivation is peerless but who is helpless in daily life. Their bizarre cohabitation begins with, "You handle the fighting, I'll handle the cooking." Using her mastery of fire control to build a fortune and her knowledge of thermodynamics to optimize cultivation techniques, she turns the tables and makes a comeback, eventually stirring up the entire world of cultivation.

The female lead's golden finger: (Mental model) Whenever her soul observes any kind of "fire" or "energy flow," it automatically constructs a "thermodynamic model" or "flowchart" in her mind, allowing her to instantly grasp its nature, weaknesses, and potential for improvement.

The male lead's strength: His cultivation is already extremely high at the start of the story, but his severe injuries limit his power and make it highly unstable. He needs the female lead's help to heal and recover.
