Holding Back the Treasure in the South, Plundering the Sheep in the North: Looking for Treasure in Half a Torn Book

[No system + first person + passionate arena + treasure hunting] In 2000, a wave of layoffs swept into small towns in Chongqing. At the age of 20, I stood at the gate of the machinery factory with 3,000 yuan in severance pay. My father passed away in a car accident early in my life, and my mother was bedridden and unable to take medicine all year round. The family's only source of income was cut off. Three days before I was laid off, I received an unsigned ordinary letter. There was only one line in the letter: "Your grandfather is still alive. If you want to find him, you must first unlock the seven mountain-holding treasures." I just thought it was a prank. Before the liberation, my grandfather Lin Shouyi went missing in the world. He lived without seeing anyone or dead bodies for decades. Even my grandma had already accepted her fate. Until the medicine bill was placed on the table again, I was desperate and pried open the dusty camphor wood box in the corner of the balcony. In the box were only half of an old book "Geographical Classic" bound with thread, half of a piece of sapphire engraved with landscape patterns, and a line of faded pencil writing between the pages: Jinan Prefecture, Deshun No., Yinjiao. In order to save my mother, in order to find out the news about my grandfather. Carrying half a tattered book and half a piece of ancient jade, I boarded the thirty-hour green leather train and headed straight to Jinan. But from the moment I dug into the Deshun's silver vault, everything went off the rails. The grievances of the sixty-three families in the south, seven in the north, the desperate pursuit of the Black Sheep Gate, the layout of the rivers and lakes spanning fifty years, and the shocking secrets behind the seven mountain towns were all unfolded in front of me layer by layer. Some people use their possessions to gain wealth and wealth, while others risk their lives to abide by centuries-old rules. As for my journey, I started from Jinan Yinjiao, and walked step by step through seven places in China to find my missing grandfather, and also walked out of my own treasure-holding world.
