It took him forty years to forge half a piece of broken jade into a Sky-Bending Blade, but he didn't know that he was the most painful wound in the cracks in the mountains and rivers. When he was five years old, Xin Qiji clutched the blood-stained Chilong Jade Jue and remembered two things while crying in Bianjing City: The Jinren's sword could cut off his mother's neck, but it could not break the dragon shadow swimming in the jade jue. At the age of twenty, he rode alone into the Jin camp and recaptured the heads of the rebel generals. People in Jianghuai called him "the swordsman in poetry", but they didn't know that he knelt in front of the furnace in Wuyi Mountain late at night, burned "Po Zhenzi" to ashes and mixed it with molten iron - those crazy words he read while drunk and reading the sword by lamplight were actually the three thousand secret roads of the Northern Expedition cast into Mo Dao. At the age of forty, when he cut off half of the emperor's sleeves during a sword dance in front of the emperor, and when the wolf head tattoo emerged ferociously from under the dragon robe, he was shocked to realize that the jade jue he had repaired for half his life was just a sacrificial vessel used by the Kingdom of Jin to refine the dragon veins of the Song Dynasty. In the last battle at the age of sixty-eight, when the Yellow River water poured into the furnace of the Imperial Seal, he smiled and threw his life's manuscript into the flames. Someone in the ashes screamed "The jade is finished", and he finally saw clearly the depth of the fire: what his mother handed over was not half a jade, but the first drop of blood that burst out when the mountains and rivers of the Song Dynasty shattered.
