Long Night Famous

In the nine-walled world, people have no city registration and will not be registered after death; demons lose their true names and degenerate into beasts while alive; demons feed on contracts; immortals receive incense but leave their vows and debts in the human world. When Jiang Yan was seventeen, he just wanted to sell a few more animal skins so that his younger brother could study in the wall for an extra month. Until he cut out a schoolboy name tag from the belly of a beast. The beast tide is coming and the city gate is closed. A demon accepted a copper coin and saved a child as promised; a human guard cut off the ropes used by people to climb the wall for five taels of silver. From that day on, Jiang Yan began to record the names of the deceased. Many years later, the immortal asked him: "If we don't sacrifice the people outside the wall, who will block the long night for the world?" Jiang Yan opened an old book full of names: "The price can be paid together, but this time, not a single name can be missing."
