After transmigrating to the Great Qin dynasty, he becomes Ying Zilin, the seventh prince, an idle young noble whom everyone looks down on. He sees through the bias in the history books, knowing that the First Emperor was no tyrant and that the catastrophe of the Shaqiu Incident is drawing near. Bound to the fate of Great Qin, he awakens a National Fortune Beast-Taming Enhancement System, allowing him to tame all kinds of beasts, upgrade exotic beasts, and exchange for heaven-defying treasures. Just as a million disaster victims in Sishui Commandery need saving and the treasury is empty, he volunteers to take an official post for three days. He breaks convention by opening the inland waterways to pleasure boats to raise funds, secretly roots out corrupt officials at court, and lies low behind the facade of a spoiled noble, determined to save the crumbling Great Qin against all odds!
