Qin Changsheng traveled through the prehistoric world, becoming a human and awakening the God-level exchange system. To survive in the prehistoric world, Qin Changsheng established an auction, selling all kinds of treasures from the heavens and the myriad realms. The auction sparked a frenzy among the prehistoric cultivators, willing to sell them even if it meant losing everything. Hongjun's voice trembled: "I even have the Jade Disc of Creation! Who dares to snatch it from me?" Laozi: "I want the Hongmeng Purple Qi." Nuwa: "You've come to the right place." Tongtian: "A killing formation even more terrifying than the Zhuxian Sword Formation! Whoever tries to snatch it from me will be in trouble." Donghuang Taiyi: "I must seize the Chaos Pearl, no matter the cost." Qin Changsheng: "If you don't buy it, how can I profit?"
