Su Wan, a modern disease control expert, fell on the front line of the fight against the epidemic. When she opened her eyes again, she became Su Wantang, the daughter of a criminal minister of the Jokhang Dynasty who was exiled to the north.
On the way to escort, fellow prisoners "resurrected from the dead" in front of her, attacking and devouring them. She recognized it at a glance—it was a plague, a plague that made the dead stand up and bite.
There is no protective clothing or vaccine, and she only has knowledge about epidemic prevention. Covering the mouth and nose, beheading, burning corpses, isolating patients, and tracing the source of the disease, she relied on these stupidest and most effective methods to snatch back the living from the dead again and again in the troubled times where corpse plague was rampant.
Until she met Xiao Jue, the king of Zhenbei, the legendary god of death who cannibalizes human flesh and drinks human blood. In order to defend the city of Luchuan, he would rather fight to the death than retreat against the emperor's orders. At first, he only thought of her as a convenient "medicine", but he didn't know that she had already smelled the poison that he had been hiding under his armor for eight years.
When the Luchuan city was destroyed, she protected three hundred people to escape through culverts; when the Canngling earthquake occurred, she held the bronze medal handed to her by the old medical officer before her death, and was shocked to realize that she was from the lineage of the former dynasty's guardians of the mausoleum, with the "blood of the key" that could open the lock of Canngling flowing in her body. The tide of corpses in the world is gathering towards Canngling. Someone wants to release the source of the corpse plague deep in the underground palace - and the key is herself.
In her last life, she failed to save a city. In this life, she stood between the corpse tide and the imperial power, and only said: "No living person can be missing."
The female doctor guards the living person, and the prince guards the city gate. In the war of troubled times, we work side by side to find a way to survive. From scheming against each other, no one can live without the other.
