Li Laoliu is an utterly unremarkable man in the city. Every day, he loses himself in stock trading, hoping to change his ordinary fate. But fate seems to delight in tormenting him. Not only is his stock-trading journey full of setbacks, but he also suffers the double betrayal of his wife and his brother, plunging his life into endless darkness. In his spare time, he likes collecting antiques, hoping to find some way out among them.
By chance, Li Laoliu spends 300 yuan on an ordinary-looking black bead. After returning home, he accidentally cuts his finger, and his blood drips onto the bead. In an instant, it shines brightly and pulls him into chaos, beginning a legendary journey.
