In the Shushan World, there were two main individuals who had mastered the art of the Xuanwu Wusha Luo Throat Blood Flame Divine Gang, one being Elder Cangxu, and the other the disciple of Xuanyuan Dharma King, the Five Lascivious Venerable.
The version that the Five Lascivious Venerable had perfected was the authentic foundational one, also known as the Golden Crow Divine Barrier; its power was also of the top tier.
Back when Dragon Slayer reincarnated as Shen Xiu and encountered tribulations in the mortal world, a conflict arose between them, and her Blood Flame Divine Gang was destroyed by Xin Ru Nun, causing her Dao Level to plummet. She later re-cultivated it but never reached the peak state, and in the end, the Five Lascivious Venerable died at the hands of Shi Feiyang, her Primordial Spirit taken into the Heavenly Secret Demon God Lamp.
