Nothing is impossible
The more the two grand figures in the Nocru community fought the deeper they fell into the state of savagery more especially Huishe Nan. The more he engaged his aether and pushed himself to the limit the more he dangerously approached an outburst.
This is why Huishe Shushi was here in the first place. It was her job to keep him rational because the moment he steps over that threshold there was no telling how far he would go. In the best case scenario, his attacks would become in discriminatory and he might harm his allies. Worst case scenario, he implodes and lay waste to everything and everyone in his path.
Guarded by several Huishe clansmen including her son and his ahem... and Captain Lan she directed her essence that one could easily describe as a fragrance towards Huishe Nan's giant true form. This process when done for a short period of time was nothing but the longer one does it the more burdensome it becomes.
