Wei Wuyin unhesitatingly used as many War Souls that could be refined in the little time left! A little over 8,000 War Souls were used! Just 8,000! He had used 1,000 to help Ma Zheng ascend, reaching the 9th Runic Ascendant State. Albeit, that was mostly his own efforts and preparations realizing itself, and likely most of the War Souls excess was expelled or remained latent within him.
Wei Wuyin remembered that Worldly Saints of the Azure-Prime Galactic Zone would be moved by a hundred or so War Souls, willing to help one convert mortals to Spiritualism. The Peak-Earth Cultivation Method—War Soul, Triumphant World—cost 8,000 War Souls as well. It was hard to gauge the value of 8,000 War Souls, especially considering Wei Wuyin had gained over 13,000,000 War Souls after single-handedly defeating the Legion of War, but he knew it was an absurd amount.
Ooooooh.
So that's why the Legion Commander showed such blatant disdain towards the Soul-Rising Saint's(Faye Liying) Domain Array! lol.
Also, the unexpected enlightement is unexpected! Wu Yu is insanely fortunate, must be his connections with Wei Wuyin. He's amped with Karmic Luck! xD
