Although Heaven and Earth Academy does not engage in power struggles, several strong individuals have emerged from its ranks, making any offensive against it akin to stirring up a hornet's nest.
The true strength of an academy does not lie in the number of powerful people it has, but in the number of talents it has cultivated.
Talent is a valuable resource for any organization.
Therefore, most powers would avoid offending an academy if possible.
The most important people in an academy are, of course, the instructors.
An instructor doesn't need to possess an extremely high cultivation level, but they must be able to guide cultivators in their practice.
Instructors are also ranked: Human, Earth, and Heaven.
Just like professions such as Alchemist, having a ranked instructor is very valuable.
The Thousands of Leaves Academy, for example, boasts two Human-ranked instructors.
Moreover, they have been invited by the Heaven and Earth Academy to teach.
