章 508: Chapter 491 Little Yellow Sparrow_1

The next day, at the hour of 2 a.m., Lu Chengyun returned to the Ten Thousand Corpses Sacrificial Altar, filled with coffins, to perform the Drawing Formation again.

Mo Hua, however, hid behind the altar, secretly watching him.

Lu Chengyun, as ever, opened a coffin, took up a Bone Pen, poured out Blood Ink, and began painting the Formation with blood. But as soon as the brush touched the surface, his brow furrowed.

He stared at the Formation for a long time, his frown deepening, and finally murmured,

"No …"

"This Formation … there's a problem …"

He had indeed been discovered.

Lu Chengyun continued, still puzzled,

"Who altered my Formation?"

"Who has the ability to change the Formation I've drawn?"

"And who could slip into the Corpse Mine under my watch, sneak into the sacrificial altar, open the bronze coffin, and alter the Spiritual Pivot Evil Formation I drew, the first-class, twelve-pattern?"
