In a remote mountain village in the 1990s, Chen Jiu'an was ostracized by the whole village after traveling as a doctor. Everyone called him the "Queen of Liars" - his grandfather Chen Zhongjing was slandered for "inciting evil and harming people" and died unjustly.
He has the ancient book "Yin Yang Medical Records" handed down from his ancestors. He has no system and no cultivation. The only reliance is on the ancient forensic medicine skills taught by his grandfather and a set of "rules" passed down orally from his ancestors - no diagnosis during the child's time, no medicine residues poured out at night, no lamplight keeping for the first seven days, and no calling out names when entering the mountain.
Zhou Banxian, the village magician, pretends to be a magician and makes money from incense while biting his grandfather's old case. The sulfur fumigants and spoiled medicinal materials of Heji Pharmaceutical in the town flowed into the grassroots. Someone in the system dug out the suppression report from that year and wanted to repeat Grandpa's ending.
"Rules are soaked in blood. If you don't follow the rules, you will die."
Look at the qi to identify symptoms, and use rules to suppress evil. A major epidemic occurred in ten villages, with zero deaths. In the barefoot doctor qualification assessment, he ranked first in the county - the person who was also the first in the county at that time was called Chen Zhongjing.
From Qingshi'ao to Anning County, he practiced medicine to solve crimes and track down old cases. Behind every weird thing, there is a forgotten rule, and behind every rule, there is a lesson learned in blood.
The truth deep in Laojun Mountain, in the dusty files in archives, and between the system and the clan, is slowly emerging.
