Loulan's Secret Word: Buried in the Sand for Thousands of Years

I have been collecting stones in Lop Nur for ten years, and the villagers call me a fool. That day, I dug out a piece of stone slab covered with strange characters from the sand. I can actually read those words. Shiban said: Loulan died not from lack of water, but from a secret. Anyone who knows this secret will die. The archaeological team arrived that day. The captain, Professor Lin, said that he saw this stone slab thirty years ago, and four of the five people he saw have died. That night, the fifth person was exposed to quicksand with seven orifices. I didn't run. Because there is a line of words on the back of the stone slab - "The blood of the city defender can prevent a death disaster." And I am the last city defender in the world. Since then, I followed the archaeological team to drill dry wells, dig thousands of corpse tombs, and descend into underground rivers and water cities. Every time a stone slab is found, the truth behind Loulan's disappearance becomes clearer - it is not a natural disaster or a war, but a deal made by King Loulan with "outsiders". Trade the memory of the whole city for a void of eternal life. The price is that the Loulan people bury themselves alive in the yellow sand, neither alive nor dead, waiting for someone to open the door to wake them up. And I am the one chosen by blood to open the door. But the seventh tablet is empty. There is only one question in the mirror: "Do you choose to open the door or bury the secret back in the sand?" Ayiguli, who accompanied me to the end, is a descendant of the Xuncheng people and the only one who could possibly kill me. She cried a lot and never let me see her. Finally she gave me the knife and walked into the sandstorm. ---
