Lu Yan possesses the rare Thunder Spirit Root, but is regarded as "half-wasted" by the sect because he cannot control the power of thunder; Su Ningshuang possesses the ancient inheritance of medicine and poison, but because she is unwilling to hurt people with poison, her cultivation has always been stagnant in the foundation building stage. When the two went down the mountain to look for the "Thunder Control Grass", they accidentally broke into the Blood Evil Cult's plot to refine the blood of monks to refine evil pills, and were surrounded and killed by hundreds of evil cultivators.
The protector of the Blood Fiend Sect holds the "Soul-Eating Flag", and the evil mist envelopes the surrounding areas. Lu Yan's thunder spirit root is suppressed by the evil force, and even the thunder technique is difficult to activate. Although Su Ningshuang protects the two of them with the medical aura, she is gradually exhausted, and is about to become the evil pill "medicine guide". In a desperate situation, the "Innate Thunder" from the thunder root in Lu Yan's body suddenly awakened. The purple-gold thunder tore through the evil mist, not only purifying the evil power, but also severely damaging the evil cultivators. Su Ningshuang also broke the knot in her heart and condensed the "life and death poison" with her dual skills of medicine and poison. Wherever the poison passed by, the evil cultivators were counterattacked by the poison.
With the two men joining forces, hundreds of evil cultivators suffered heavy casualties, and the Blood Evil Cult's conspiracy was exposed. But they don't know that this is just the tip of the iceberg of the Blood Demon Sect's "Blood Moon Slaying Immortal Plan". More powerful evil cultivators have been secretly eyeing their spiritual roots and inheritance.
