Sauron's Arrow

In the winter of the 34th year of Kangxi's reign, Erdun, a seventeen-year-old boy from Sauron, hunted a bear alone on the snowy plains in the upper reaches of Heilongjiang. The clan didn't allow it, and it was a taboo for someone to empty a warehouse alone; but he had to do it this time, because someone from the camp said, "We need people from the west," and the west was the direction where his father died five years ago. All that my father left behind was a half-broken knife, an unfinished letter, and half an old picture of a landscape and road. He entered the military camp with these three things: learn to read people, learn to keep accounts, learn to survive between paperwork and grain scales, and also learn to identify the things hidden under seals, cuffs and names. Some people paid high prices for "old pictures from outside the customs." Some people looked through his pictures with one hand through the curtain, and some people asked him on the snow, "What's your mother's surname?" Step by step, he went west, his arrows shot more and more accurately, he knew more and more things, and he also understood more and more: investigating his father's death is the most dangerous thing in the world.
