Immortal Alliance.
A certain frontier Immortal City.
Inside the secret chamber deep within a courtyard.
At this moment, a figure sat cross-legged atop a Cloud Bed.
That was right.
It was none other than Cheng Buzheng's true body.
At this moment, he held a Jade Slip glowing with a faint sheen in his hand, seemingly recording something.
A short while later.
The faintly glowing Jade Slip in Cheng Buzheng's hand suddenly dimmed.
