Xu Qingtong suppressed his doubts and picked up another stone box. When he opened it, he found another jade slip. A sweep of his divine sense revealed a spell called the Blood-Burning Spell, also recorded in Human Race writing.
He examined several more boxes. Without exception, they all contained jade slips.
One of the jade slips, however, greatly interested Xu Qingtong. It contained a cultivation method called the Demon Transformation Great Method, created by Lian Shaocheng.
