"The Order of the Blood" is a medical conspiracy novel based on an imaginary female dynasty. The story revolves around Lin Siyue, a young medical officer who resolutely proposed a reform plan to establish a universal and safe "official blood bank" when the empress was seriously ill and the outdated and decadent "blood bank" monopoly system endangered the country. This move aimed to bring blood resources back to the government and establish a modern system from blood source management, testing and storage to clinical infusion. However, it touched upon the intertwined century-old interest groups. By depicting the fierce game between institutional innovation and vested interests, the work deeply explores profound propositions such as medical ethics, resource allocation, and social fairness. It shows how, in the gap between power and life, idealists rely on the benevolence of doctors and political wisdom to carve a way out of a bloody mess.
