Cheng Lingzhu spoke softly.

She tilted her head, leaning on Lu Xuan.

Lu Xuan wrapped his arm around her shoulder, drawing Cheng Lingzhu's hand into his palm.

In short, on this particular day.

"Come on, let's test the results of our joint efforts over this period."

Lu Xuan, holding Cheng Lingzhu's hand, led her to a grand hall.

This hall was unique, spacious and empty, with no furniture or lamps.

The ceiling was embedded with 108 special jade stones, forming an array that locked the space inside the hall and also provided illumination.

The most distinctive feature was the walls of the hall.

The hall was an octagon, with eight walls, each dark and constructed from a special kind of stone.
