The primordial spirit was formed from the condensation of all a cultivator's energies, so it could activate spells that shared the same source as the cultivator's own cultivation technique.
But there was one prerequisite.
The spell had to be cultivated to the point of developing a spirit. Only then could that "spirit" be merged into the primordial spirit, allowing the spell to be activated with primordial spirit power.
A primordial spirit spell formed this way was equivalent to a life-bound spell. It could be unleashed and withdrawn at will, and its power would be greater.
Furthermore.
If he could turn Five Thunders Smite the Crown into a primordial spirit spell, there would be no drawbacks to using it to condense his primordial spirit domain.
Chen Lin suddenly felt that a vast road had opened before him, the fog clearing away.
According to the text, a primordial spirit domain could be formed by fusing multiple spells and divine abilities, but they might conflict with one another, making the domain unstable.
The more spells were fused, the worse the conflicts became, and the harder it was to raise the domain's level.
But his innate divine ability and Five Thunders Smite the Crown were both his life-bound spells. Fusing them would not cause any rejection; instead, they would complement each other.
With delight on his face, Chen Lin put the text away. According to the theory it described, the problem of condensing his primordial spirit domain was as good as solved. He no longer needed to agonize over which spell to use.
His only regret was that his second primordial spirit had not been formed from his own mana, so it could not turn Five Thunders Smite the Crown into a primordial spirit spell. To use it, he would still have to wait
