The emergency doctor dressed as a Taiping Army handyman and crawled out of the corpse pile by relying on battlefield first aid. There is no black technology, just a scalpel and medical knowledge that is 150 years ahead of its time. He saved King west, built a hospital, and fought against the plague. He was appreciated by Yang Xiuqing, but he was involved in the internal strife in Tianjing. He improved the military system, implemented health regulations, and walked a tightrope between theocracy and the butcher's knife. When history was destined to overthrow, he chose to plant a fire for future generations - the kingdom of heaven will eventually fall, but civilization should not be buried with it.
