Zhang Tie had not used the secret art of external incarnations many times. In Yunhezi's last letter, he had warned Zhang Tie that the external incarnation technique consumed the source of one's soul and spirit. This could be said to be its greatest hidden danger. Therefore, no one cultivating the Great Wilderness Scripture could endlessly and casually use Soul-Possessing Beast Control. Every additional incarnation was equivalent to weakening the soul-source of the original body by a thread. Zhang Tie had originally worried that Soul-Possessing Beast Control might leave some aftereffects, but after eating that Origin Fruit, he finally understood that his worries had been unnecessary. The power brought to him by the Origin Fruit was precisely the thread of power that the Great Wilderness Seal Pact drew from his body whenever he established an external incarnation.
From beginning to end, Zhang Tie had possessed three external incarnations: a rat, a Thunder Falcon, and that little black beetle. When establishing those three incarnations, the source energy of Zhang Tie's original body had each suffered a slight depletion. Yet compared to what Zhang Tie had gained from the Origin Fruit, that depletion was utterly insignificant. If the source energy Zhang Tie had obtained from the Origin Fruit were compared to a large vat full of water, then the source energy he had expended those first three times amounted at most to the tiny drop that dampened the tip of a brush. The source energy contained in the Origin Fruits plundered from 360 Winged Devils at level nine and above was naturally tens of millions of times greater than the source energy required to control a rat, an insect, and a Thunder Falcon.
Back in the Great Wilderness Sect, there had been countless secret medicines and treasures of heaven and earth to replenish
