The Ancient Tree Inheritance is a form of Body Refining Inheritance.
In fact, the life forms within the Primordial Chaos Ancient Tree Space are essentially semi-plant life entities, and their physical bodies are not inherently strong. The Secret Techniques they practice also primarily focus on Body Refinement.
Of course, the inheritance that Jing Yan is now receiving is extremely rare, even within the Ancient Tree Space. This inheritance is the Ultimate Inheritance, theoretically allowing one to surpass the ultimate when cultivated to its peak. The Ancient Tree Elder practiced this Secret Technique.
