After witnessing Senior Sister Liao Feibai's condensed casting of her life-bound Profound Yin Nine Tribulations Sword, which lasted eight days and seven nights, Ye Zhen was utterly flabbergasted.
With the help of Purple Spirit, Senior Sister Liao Feibai had comprehended a complete law of Profound Yin Sword Qi.
The next step was to activate this Profound Yin Sword Qi Law, continually gathering the Profound Yin Energy from the world into her life-bound Profound Yin Nine Tribulations Sword, thereby strengthening the sword.
Moreover, this Profound Yin Nine Tribulations Sword Formation, inherited from the ancient times, inherently possesses a bit of the power of the Profound Yin Sword Qi Law, which can gather the world's Profound Yin Energy while the sword formation operates.
With this assistance, the cultivation effect of Senior Sister Liao Feibai was even more remarkable.
