It took several months of constant training before Kexin could fully control her own elements. Demonic Qi was not as inclined to make shields like standard Qi. Lind had to literally create the concept from scratch.
Wyndam was instrumental in working out the testing steps with Kexin but unlike Lind, he could not use demonic Qi at all. Lind was unique in how he branched out into the demonic Qi control for elixirs and Forging at least.
Lind also trained with the soldiers and maids. Most were taciturn or battle maniacs, not exclusive to either camp strangely enough, but he had them change to the robes of the Moebius Sect. His training battles were 2 to 3 at a time which garnered a lot of attention.
Kexin even came to watch once she was able to move without risking her control of her Qi. She was still only a Tier 3 Demon Soul Realm, but her skin that had once been pale as a ghost was a very light shade of lavender now.
