Jian Qinghe was born in the Jian family, a family of medicine. He studied incense and poison theory with his father since he was a child. He could use strange incense as medicine to save people, and he could also use incense to control enemies and kill people. When she was fifteen years old, the entire Jian family was wiped out, and she was the only one to escape with her ancestral book "Secret Records of Incense and Poison". From then on, she traveled around the world incognito. While she was helping the world and accumulating connections, she was secretly tracking down the real culprit who destroyed her family. She can mix incense with her bare hands, which can cure strange poisons in the world, and can also kill people. Dressed in green clothes, she looks like a weak medical woman, but in fact she is ruthless in her methods. All the young men in her sect who provoke her fall under her incense skills. While walking around the world, she always met a grocery vendor named Aheng. The man looked ordinary, traveling around with a peddler's load. He had an easy-going temperament and always had a smile on his face, but he always happened to appear when she was in danger, fending off pursuits and resolving fatal situations for her. At first, Jian Qinghe just thought it was a coincidence, until she was surrounded and suppressed by the five sects, and her body was poisoned and her life was hanging by a thread. The man fell from the sky, broke the situation with a sword, and had a frightening aura around him. Only then did everyone recognize that he was Ling Heng, the current leader of the Jianghu Alliance who had retired for three years and had unfathomable martial arts skills. No one knows that Ling Heng disguised his identity and traveled among the people, just to find out the unjust case and the undercurrent of the martial arts competition that year. When he first met Jian Qinghe, he recognized that the incense in her hand came from the Jian family, and he also saw the hatred and vulnerability in her eyes. From meeting by chance to walking side by side, from testing each other to delivering sincerity. She used the secret technique of incense and poison to help him clear up the fog of the world and find out the truth about the unjust case; he protected her with the respect of the leader of the alliance, avenged her family's blood revenge, and healed her half-life pain.
