Lu Ya was Saint Zhunti's disciple, so he knew many spells of the Western Religion. Of its more formidable cultivation arts, however, he knew only two. One of them was "Supreme Freedom Under Heaven, Vajra Demon-Subduing Divine Ability."
Chenxiang had said that he would go up to Heaven to rescue Yang Jian one day, and those words should have come from his heart. That was why, after erasing his memories, Lu Ya had decided to come here as Zen Master Crow's Nest and teach him. Once he mastered this art, together with his own Eight-Nine Profound Art, perhaps, possibly, maybe... he really could sneak into the Heavenly Court and rescue Yang Jian.
That will repay the kindness I owed Yan Zuo back then, Lu Ya thought.
As for Chenxiang not knowing, after losing his memories, that the Heavenly Court had used the power of the Investiture of the Gods List to capture Yang Jian again, that was easily handled. Chenxiang still remembered how Yang Jian had risked his life to save him at Mount Hua, holding Yinglong back for him. Lu Ya only needed to find an opportunity later to tell him about Yang Jian's current circumstances, and he would naturally know what to do.
What? Ao Yue had already publicly cast Yang Jian into the Land of No Return Across Ten Thousand Calamities?
Lu Ya, who had been busy settling Chenxiang and the others all this time, had yet to hear that news.
Even once he heard it, it would not matter. He only needed to change the destination and have Chenxiang rescue Yang Jian from the Land of No Return Across Ten Thousand Calamities instead of the Heavenly Court.
At that moment, he was explaining the essentials of "Supreme Freedom Under Heaven, Vajra Demon-Subduing Divine Ability" to Chenxiang.
