The Five Poison Heavenly King, Lie Baduo, originally came from a barbarian clan in the great mountains. Since birth, he had scales growing in reverse direction and a mouth full of sharp fangs, along with immense strength enough to tear tigers and panthers apart with his bare hands.
At about thirteen, he had a freak encounter where he mistakenly consumed the gallbladder of a poisonous python and an Immortal Herb. On the brink of death, he miraculously transformed and became a handsome young man.
Later, he fell in love with the female Sword Immortal, Yun Luo Niang, who took him in and introduced him to her master, Wei Bagong. Initially, he learned a host of peripheral Immortal Laws from Wei Bagong. However, having developed marital problems and feeling mistreated by his mentor, he left in anger and became a disciple of Wei Bagong's rival, mastering various Demon Techniques and Evil Magic.
