Xuan Tu: "If you have any other requests, you can make them."

Old Fang was somewhat tempted.

Opportunities to make demands of Xuantu are few and far between.

To be precise, it's extremely rare.

He only encountered it once.

"What if the Heavenly Book asks me for something I don't have, or something I can't give it to?"

"Then forget it."

"Okay, then, but I can't think of any other requirements for now, so I'll just keep them for now."

Xuan Tu immediately grabbed him and stepped into the black hole.

In no time at all, they arrived at the Heavenly Book Pavilion in the Heavenly Book City.

The Heavenly Book stands inside, worshipped and revered day and night.

Old Fang straightened his clothes and went inside.

He came out shortly afterward, looking completely bewildered, and said, "The Heavenly Book says that the Heavenly Demon Bone is both far away and right before our eyes. What kind of riddle is it playing?"

"Right in front of me? Where?"

He looked around in all directions.

"All I see is you—wait, the Heavenly Demon Bone it mentioned, could it be on your own body?"

He was thinking that Xuan Tu might have obtained the Heavenly Demon Bone at some point, but he himself did not realize that it was the Heavenly Demon Bone.

Xuan Tu, however, knew that there were no bones in his Xuan Ring.

The only one with bones was himself.

Heavenly Demon Bone... Heavenly Demon Gu...

"Could the Heavenly Demon Gu be the kind of Gu that can turn people into demons?"

Old Fang's casual remark from before now echoed in his mind like the resounding sound of a great bell.

I recall how I used to lose control whenever I had a headache, becoming like a demon, relentlessly killing.

Xuan Tu suddenly had a guess.
