Zhang's eyes flashed with understanding, and she said, "Are you saying that because of the death of Tianhe Venerable, the Tianhe Sect was restricted from researching array formations by the Four Sects?"
"What you say is exactly what I'm thinking," Zheng Fa speculated. "In the Xuanwei Realm, only the Four Sects have the power to completely prevent the Tianhe Sect from developing array formations, or even deliberately avoid their research."
Xie Qingxue frowned, still puzzled, "This is possible, but there's no evidence."
"There is evidence! Within the 'Heaven and Earth Divine Evil Formation' lies your Tianhe Sect's sword refining method!"
Zheng Fa's words shook Xie Qingxue to her core.
"Of course, I haven't studied the Tianhe Sect's sword refining techniques deeply, but I can detect some slight traces in it."
"The 'Heaven and Earth Divine Evil Formation'?"
