The avatar was of a Heavenly Spirit Root, with a cultivation speed of 100, while the main body's cultivation speed was only 38.79.

Spiritual Power recognizes its master, and under normal circumstances, the feasibility of this idea was almost zero.
While Spiritual Power is extremely obedient within a cultivator's body, that's because it is cultivated by the cultivator themselves, bearing the cultivator's own soul imprint.
The same Spiritual Power, once it enters another cultivator's body, becomes a highly destructive attack.
