1217 BC·Bronze Ruins in the late Shang Dynasty: The "Yanci Ruins" on the south bank of the old Yellow River was once the capital of the Xuanniiao tribe of Dongyi. It was reduced to ruins due to a mysterious natural disaster three hundred years ago. When modern archaeologist Li Chenguang led the "Bronze Civilization Expedition Team" to excavate here, they accidentally unearthed a rusted bronze sword engraved with nine spiral patterns - the "Black Bird Bronze Inscription" on the sword actually matched the legend of "Broken Sword to Suppress the Dragon" in the fragment of "The Classic of Mountains and Seas: The Great Wild East Classic".
With the emergence of the "Hanging Coffin Array" under the ice and the "Bronze Star Chart" in the cave, team member Lin Wanqing discovered that the sword pattern concealed the ancient calendar of "dividing the field and establishing the energy". Uncle Ya, the old tomb protector at the archaeological team's station, always gestured the lost "Xuanniao Sword Technique" against the shadow of the sword on moonlit nights. When the Beidou hangs its hilt on the night of the autumnal equinox, the bronze sword absorbs the moonlight and reveals the inscription "Blood Contract of the Human King". The memory of Zhu, the great shaman of the Black Bird Tribe, who forged the sword with his soul and sealed the Yellow River flood thousands of years ago, actually flooded into Li Chenguang's consciousness through the resonance of the sword blade - he saw himself three thousand years ago, inserting the broken sword into the dragon's head-shaped altar.
