After ten thousand years, one Lower Wind Rune remained, while the Middle Wind Runes had become five.
After another thirty thousand years of consumption, the nine Middle Overlord Blade Marks were finally fused and advanced, becoming one thicker Overlord Blade Mark.
At this point, Lin Xuan also possessed a Superior Law Rune.
"Advancing from middle grade to superior actually consumed thirty thousand years of cultivation time."
Looking at the remaining 51,850 years of cultivation time, Lin Xuan once again felt how scarce cultivation time was.
