Dragon Soul Traceability

On the banks of the Chishui River that has been flowing for a long time, a legend of "dragon's blood protecting the river" has been passed down from generation to generation among the people like a spark, lasting for thousands of years. Whenever there is a heavy rain, the river surges like a wild horse, and when the turbid waves are emptying, there is always a huge shadow with flashing red scales breaking through the turbulent waves. The giant shadow has a vigorous figure, like a god coming to the world, stirring up thousands of sprays of water, and with an awe-inspiring momentum, protecting the people along the coast for generations, protecting them from the ravages of floods. However, the wheel of time was turned back a hundred years ago, and a sudden and mysterious "Blood River Disaster" enveloped this peaceful land like a haze. For a time, the river turned into a color as thick as blood, and the stench filled the air for hundreds of miles. Strange phenomena occurred frequently in the river, and the villages along the river seemed to be cursed. Crops failed to harvest, and diseases were rampant. The once lively and prosperous scene was gone forever, and it quickly declined and withered. Since then, the legend of the River God has become a taboo that everyone avoids, and those who mention it look terrified. As time goes by, only the Lin family, like a lone lamp in the wind and rain, sticks to this increasingly desolate land for generations. In that dilapidated ancestral hall with spider webs everywhere, they worshiped half of the bronze sword devoutly. The sword body is engraved with mysterious scale patterns, which seem to tell the glory and vicissitudes of the past, and also seem to hide the key password to unlock the mysteries along the Chishui River, attracting people's endless reverie.
