Actually, Sage Dong's guess towards the actual scenario which had happened to Li Moying was especially close.
Li Moying had indeed obtained a huge amount of Profound Energy replenishment after he killed the spiritual beast Qilin, hence obtaining the foundation of breaking through.
But Sage Dong could never have guessed that Li Moying was already a ninth stage realm peak practitioner in his past life. His memories had been activated during the full moon's night under both activation of memories and provocation, he was able to succeed in advancing under coincidental opportunity.
Furthermore, the most important thing was something which both Sages would never have expected in their wildest dreams. Li Moying was merely twenty one years old this year, much younger than what Sage Dong and Sage Wu Ding had expected. So it was foreseeable that based on his innate talent, breaking through to the tenth stage realm would not require a long wait of ten years or so…..
