The Formation, although having the characteristic of autonomously maintaining itself before energy reserves are depleted, ultimately requires cultivators to control it; only then can its power be maximized.
Simply put, Unparalleled Island's protective array currently has some energy reserves. However, when defending against invading enemies, this energy is continually consumed. Once the reserved energy is exhausted, the protective array can no longer be maintained.
The only way to persist longer is to manually control the array by injecting spirit force from cultivators into the array hub or look for ways to stimulate the power of the spirit jade to supplement the array.
But no matter how you do it, manpower is essential!
And the biggest problem Unparalleled Island currently faces is the shortage of manpower!
Thus, Chu Shen didn't even consider just defending, because in the present situation, mere defense is futile; a counterattack is necessary to have any glimmer of hope.
