Upon hearing the Sword Saint's request, Mufeng immediately knew what he was talking about.
In the original work, there was a senior in the Demon-Suppression Tower named Jiang Qing, who fell in love with the demon woman Yue Rouxia and fathered a daughter named Jiang Wan'er inside the tower. (This refers to the original video game; in the television adaptation, the person inside the tower was Jiang Ming, who fell in love with a nine-tailed fox, and the daughter they had was also named Jiang Wan'er. The overall story was similar with minor differences in details.)
Jiang Qing had been an elite disciple of the Shushan Sect back then, mastering the sect's ultimate technique, the Tiangang Sword Array. At that time, the Demon Lord Huntian was close to completing his demonic arts, and the Shushan sect leader decided to deploy the Tiangang Sword Array to eliminate him.
