Xu Yuan and Lou Ji entered the secret room, and the inscription lamps that responded to their presence immediately lit up.
The nucleus of the Protective City Formation of Huizhou County was contained within a cave approximately seventeen or eighteen zhang deep, shaped like a rectangular prism, with its walls smoothly plastered with special stones and stone stairs spiraling downward at the edges.
With the light from the inscription lamps, the numerous profound formation patterns engraved at the bottom of the cave were faintly visible.
Walking down the stone stairs to the bottom, the steps of the two echoed in the spacious and quiet cavern.
As they gradually approached the bottom, Xu Yuan gazed at the formation patterns, which flickered between brightness and darkness, and a touch of admiration involuntarily appeared in his eyes.
The art of formations was indeed a marvelous creation of humankind that cleverly rivalled the works of the heavens.
