The Holy Pillar was the backbone of the will of the entire demon world.
Furthermore, it was the Holy Pillar that had created the scepter in Demon Saint's hand. It took ten Heavenly Dao at the very least for the will of a world to come into being. Therefore, even if Demon Saint had yet to reach Venerated Immortal level, as long as he was supported by the power of the will of the demon world, he wouldn't necessarily be weaker than Zhenyuan.
Loopy Toad had already taken this into account at the very beginning, but it hadn't expected Demon Saint to be decisive in borrowing the Holy Pillar's power to drive the will of the demon world.
Deep down, Loopy Toad felt something wasn't right.
This was an "arm wrestling" play being acted out, and the main stars were Zhenyuan and Demon Saint. But in fact, Loopy Toad realized the one that was truly being tested was itself.
