Zhang Yuan turned his gaze to the [Sun-Eroding Demon King Palace], picked up the Pre-Heaven Supreme Treasure that had automatically bound itself to him, and pondered.
"This supreme treasure is bound to me, and I've already formed an outer dao golden core. Even without the slightest celestial conceptual image, I should be able to activate its divine effects with outer dao magic power. But that's only the ideal outcome..."
The [Sun-Eroding Demon King Palace] had two divine effects.
The [Eroding the Sun] effect allowed the [Sun-Eroding Demon King Palace] to be raised into the heavens to devour sunlight and turn it into slaughtering black light. It was an immensely powerful offensive divine effect; even a Celestial Person would have to expend vast amounts of conceptual images to activate it.
The magic power of early outer dao golden core probably could not sustain the activation of the [Sun-Eroding Demon King Palace]. By Zhang Yuan's estimate, even activating [Eroding the Sun] at its lowest level would require, at the very least, all the magic power of someone at outer dao golden core perfection to the Nascent Soul Realm.
[Eroding the Sun] was unusable at his current stage, but the other divine effect of the [Sun-Eroding Demon King Palace] could be activated with early outer dao golden core magic power. Its effect also happened to be extremely useful for his present circumstances.
[Beholding Demons].
This divine effect acted upon the [Sun-Eroding Demon King Palace] itself, allowing it to become a temporary cultivation sanctuary and traveling palace. Those within could improve their spirit root quality, increase their qi gathering and qi refining efficiency, accelerate refinement, and receive the Demon King's Dharma Transmission. The drawback was that it would slightly stimulate evil thoughts and desires.
The drawback was negligible.
