To defeat him in an open, head-on fight, Liu Yu would probably have to wait until he reached the late stage of Foundation Establishment.
He was not without advantages of his own. Liu Yu analyzed their respective strengths and weaknesses.
His divine sense was naturally stronger than that of others at his level, and he also cultivated the Divine Preservation Art. Once his divine sense reached the late stage of Foundation Establishment, it would be effective against Li Butong.
If Li Butong had no magical artifact specifically designed to defend against divine sense attacks, Liu Yu would hold a certain advantage in their clash.
Liu Yu silently weighed the comparison. He had already begun treating this Top-tier Foundation Establishment cultivator as a hypothetical enemy.
While Liu Yu was thinking, Li Butong had already begun to lose patience.
In Li Butong's eyes, this was merely an insignificant Foundation Establishment lineage. Before the heavenly might of the Primordial Yang Sect, they ought to bare their necks for execution.
They would die sooner or later, yet they still dared to waste his time. They truly did not know what was good for them!
Li Butong's robes billowed, and his long hair rose into the air. The Treasure Sword, apparently a top-grade spirit artifact, hovered before him as his hands rapidly formed hand seals.
The pale azure Treasure Sword swiftly expanded. In the blink of an eye, it became a giant azure sword roughly thirty feet long and two feet wide, brazenly radiating formidable power.
Then the runes on its blade flickered, activating the demon beast soul sealed within.
It was Spirit Artifact Transformation!
An azure flood dragon slowly materialized, enveloping the spirit artifact.
The flood dragon had a magnificent horned head and an imposing presence. Every scale on its body was clearly visible.
