As Core Disciples of the Yaochi Sect, both Senior Sister Liang and Senior Sister Ji were acutely aware.
The so-called Mystic Lady Exterminating Immortal Sword Skill was an overpowering Forbidden Technique that transcended this plane of existence, and only those with a specific constitution could cultivate it.
In the history of their Yaochi Sect, there had been only three who could cultivate this Forbidden Technique.
One was the first Sect Leader of their Yaochi Sect, another was their current Sect Leader, Yao Ling'er, and the last one was Tang Mengyun herself!
Although Tang Mengyun was capable of cultivating this technique, Yao Ling'er had once said that unless Tang Mengyun's cultivation reached the Nascent Soul stage, she must never use this skill.
Once deployed, it posed the danger of eradicating both her body and soul, which was the real reason why Senior Sister Liang and Senior Sister Ji were so shocked upon seeing Tang Mengyun use this technique.
