The black water plot in the movie "Zhou Chu San Xu" was actually a deception method, which was achieved by adding drugs to the food of the deceived. From a medical point of view, this drug might be iron. An excessive amount of iron would react with gastric acid and other stomach components in the digestive tract to form black iron sulfur. At the same time, it would cause adverse reactions such as dry mouth, nausea, vomiting, diarrhea, and even vomiting. However, the movie did not clearly explain the composition of the drug. Lung cancer would not directly cause upper digestive tract bleeding, but medication, stomach or liver metastasizing could cause upper digestive tract bleeding. Therefore, the plot of Blackwater in the movie was fictional and did not represent the real medical situation.
