How did the history of Yadong black Tianma come about

The elixir happened to fall onto a huge rock in Changbai Mountain. After a loud sound, the rock split in half and then rolled into the grass. In the second year, two things of different shapes grew: one was emerald green with stems and leaves; The other one is light yellow in color, with stems but no leaves, and a fist shaped object growing on top of its head

One day, ginseng and Tianma arrived at a village and saw a group of people kneeling in front of a temple, burning incense and muttering words to the pigs and sheep offerings placed there.

. The two of them noticed that these people were mostly yellow skinned, thin, and listless, so they asked an elderly person what was going on. The old man told them that many years ago, a sudden rain of blood fell from the sky. Since then, people's health has been deteriorating. They either suffer from this disease or another disease, but due to the lack of a cure, they have to worship gods in order to save their lives

The young man's name is Baozhu. He looks like he's sixteen or seventeen years old. In addition to helping to grab medicine in the store, he often goes to the mountains with his master to collect herbs. That day, Baozhu went up the mountain to collect herbs and met two fairy like girls in the old forest, one in green pants and a red coat, and the other in yellow and purple pants. Baozhu was very surprised. Where did the girl come from in this mountain? So he asked where the two girls came from. Ginseng and Tianma said they just moved in from the foot of the mountain and live not far away. So, the three of them sat on the grass chatting leisurely. After chatting for a while, their topic turned to medicinal herbs. Ginseng lowered its head and pinched a ginseng leaf, saying to Baozhu, "Baozhu, why don't you pick it? Let me tell you, this is called ginseng. It is a tonic that greatly replenishes qi, strengthens the spleen and lungs, generates fluids and quenches thirst, and soothes the mind and enhances intelligence. You can dig it back, but it has great use!" Tianma also pointed to a light yellow object and said, "Look, this medicinal herb is called Tianma. It can dispel dampness, relieve pain, promote qi and blood circulation. You should dig some too." Baozhu was very obedient and dug up some ginseng and Tianma before going down the mountain. Since the introduction of these two medicinal herbs, the reputation of their pharmacy has gradually increased. Some previously incurable diseases have been gradually cured, people's health has improved, and the village is filled with laughter and joy
