The declining Demonic Sect: Sect Master Shen Linyuan wholeheartedly wants to revitalize the sect, outwardly disguising it as an immortal sect to recruit disciples everywhere. By chance, he picks up the clueless orphan Su An'an and discovers that she possesses a rare innate Dao body, so he tricks her back into the Demonic Sect, intending to cultivate her into a demonic combat force. However, Su An'an is actually the incarnation of the Heavenly Dao, immune to all laws. Shen Linyuan and several disciples with unique skills pull out all the stops: the poisonous elixir cauldron, sacrificial sword bone blade, ten-thousand-poison blood pool, and divine soul puppet arts take turns in deployment, wanting to eliminate this hidden danger.
