Jinse Qingshuang

After the ancient water god Gonggong was angry at Buzhou Mountain, his broken godhead and spine turned into a "Xuanyin Earth Vein" that stretched for thousands of miles, diving deep into the ground, forming a "Yingying Dark River" that poured into the underworld. Legend has it that the depths of the underground river are not stagnant water, but the entrance to the "Eye of the Northern Dark Sea". Every thousand years, the "Nine Nether Turbid Waters" that are enough to corrode fairy spirits will spew out. The evil energy of the underground river is too strong, and hitting the ground will cause the people to be devastated. The three Taoist ancestors, Taishang Laojun, Yuanshi Tianzun, and Lingbao Tianzun, came and each used their supreme supernatural power to enlighten the three sacred mountains, turning them into three "suppressing evil sky bridges" across the abyss. These three bridges are not ordinary stones, but are made of three different "Qingwei Tianlei Talisman", named "Yuqingsuo", "Shangqingjin", and "Taiqingfeng" respectively. They are shaped like a pin and lock the dragon's energy in the underground river underground. This place is an extremely rare "yin and yang junction" training ground. There is abundant spiritual energy above the water surface, which is suitable for righteous sword practice; in the underground river caves under the water surface, there grows the "Bianan Lingpu" (corresponding to the cattail flower) that absorbs the spirit of the netherworld. Taking it can strengthen the soul, but it can also easily make people fall into the devil's way. The ancient town was set up as a "boundary city", and only monks with the Taoist mark could stay here to prevent underground demons from escaping through water.
