Boom! Boom! Two True Immortals simultaneously retreated backward.
"Formation! Activate, kill!"
The black-robed elder manipulated Anshun City's guardian array, instantly changing the colors of heaven and earth, producing endless green light that directly formed an enormous battle axe, fiercely slashing toward Li Yuan.
Relying on the formation, he could exert far superior strength than his own.
"The might of this formation can be considered the pinnacle of True Immortal." Both the black-robed elder and purple-robed middle-aged man held a trace of expectation in their hearts.
Li Yuan also moved instantly, a divine spear appearing in his hand, thrusting directly. A dazzling spear light cut through the vast sky, instantly shattering the battle axe condensed by the formation's power. The spear light continued to cut through the bodies of the black-robed elder and purple-robed middle-aged man.
The faces of the two True Immortals changed: "What?"
