Chapter 421: Empyrean Lord's Two Disciples

The three flying swords streaked across the sky like three white beams of light as they launched attacks from different directions.

The Boor Ancestral Sect spent hundreds of thousands of years setting up array formations, making improvements every generation, making it an impregnable fort to outside forces.

Even if Daoist Divine Firmament and company had the means to crack the array by force, they could not prevent the collateral loss of lives of the mortals within.

"It's relatively easier to destroy from the inside but these array formations are stacked over each other, making it like a thick fog. The interior levels can only be destroyed after the exterior levels are destroyed. It will probably take some time to destroy them one layer at a time." Qin Yun felt the pressure. He needed to maintain the Cosmic Bangles' suppression on Jiuhu as well as endure the hindrances of the Eight Gates Fiend Saber Array.
