While the grand performance had yet to commence, Yang Xiao had walked back and forth a few times to familiarize himself with the layout, remembering the old man's reminder that food that had been "eaten" must not be discarded carelessly, but rather stacked by the incense burner.
It was only upon getting closer that Yang Xiao noticed a long yellow paper under the incense burner, resembling a talisman, covered in incomprehensible ghostly script and a string of words that looked like a birthdate.
After checking four incense burners and finding talismans under each one with matching birthdates, it seemed certain that this was indeed Xi Yao's birthdate.
