Taiwei was correct. The demonic and divine clans only recognized one Blood Manifestation: the Dharma Release. The Dharma Release was proof that the warrior had cultivated their bloodline to the peak, mastering all their bloodline skills, and unlocking the true battle prowess of their blood.
But to make up for her inability to learn most martial skills, Taotie pushed her bloodline cultivation beyond that limit, developing a Second Release. In the Primordial Era, though Taotie normally ranked third among the Four Perils, once she activated her Second Release, even Hundun had to tread carefully.
Sadly, in the past, Taotie couldn't maintain her Second Release for over 10 minutes—making sure that all enemies that witnessed that form didn't live to spread the news. But after billions of years of isolation and nothing to do besides polishing her skills, the gluttonous demoness managed to push that limit time and time again, now able to maintain her Second Release for an entire week.
