Sects like Xueyang Sect and Shixian Sect were hated by the underworld because these guys would greatly reduce the underworld's performance.
If Lu Yuan proposed to let the underworld help him attack the Shixian Sect together this time, the underworld would definitely not refuse.
Moreover, because most of the people in the Shixian Sect had heavy karma, not only would Lu Yuan not be punished by the heavens, instead might even receive merits. It could be said to be killing two birds with one stone.
However, Lu Yuan was worried that there might be some old monster behind the Shixian Sect, so he had never thought about whether to use Plan B.
After all, compared to Plan A, Plan B lacked the help of ten Nascent Soul Stage cultivators.
The difference in battle prowess was not small.
However, he clearly did not have many choices at this moment.
