Sword Name: Thousand Thoughts!

On the top floor of the building, Liu Shuyue stood at the center of the grand formation, presiding over its operation.

Her robes fluttered without wind, while blue ripples continuously spread beneath her feet.

Within a hundred-meter radius around her stood four pillar-like metal structures. Miss Lin said they were the building's antenna equipment. Ji Yun did not know what antennas were, but they were well suited to serve as formation anchors. Hundreds of talismans were pasted onto each pillar, rising and falling with the blue ripples as though breathing.

This was the Demon-Subduing Formation laid down by the Immortal Master.

Unlike formations activated with talisman paper, this was a sect grand formation. Its formation eye had to be guarded by Cultivators in order to function, and the more Cultivators there were, the stronger it became.

After many years, Ji Yun was once again learning new techniques from his master.

Once Demons were trapped within the Demon-Subduing Formation, they could not leave its range no matter what they did. They either had to destroy the formation eye and render the formation ineffective, or kill every enemy within the formation in order to survive.

The latter was generally difficult to achieve, because formations usually waited at leisure for their targets to walk into the trap. Thus, breaking the formation eye was usually the first consideration.

That was why grand formations generally also required Cultivators to guard them.

Although towering, magnificent skyscrapers stood everywhere
