Chen Yuan, a modern business elite, accidentally traveled through the Zhenguan period of the Tang Dynasty. He was penniless but activated the "richest man system". Waking up from a cold night in a ruined temple, he started his business based on a plan of improvement, saltpeter ice making, Hu-Han merchants, Silk Road trade... Step by step from a hawker in the West Market to the richest man in the Tang Dynasty. Li Ke helped each other, Cheng Yaojin protected the field, Taizong asked questions before the emperor, business wars and court games were intertwined. When the Zhenguan banknote was born, when the first roar of the steam engine resounded through Chang'an, a business empire that transcended the times was rising.
