The Emperor System Arrived Sixteen Years Late, but I'd Already Won by Doing Nothing

[Transmigration + System + Conquest + Power Fantasy + Political Intrigue + Strategists] Li Qing transmigrates as the heir to the Prince of Beiliang. For sixteen years, he lies flat while the border troops fight, eating meat and drinking wine. Life couldn't be better. After all, his father is the Prince of Beiliang, and he's an only son. Inheriting the family business is just a matter of time. Then one day, after a night raid, the System suddenly appears: “Emperor System, officially activated.” Li Qing: “???” Now you show up? Where were you all this time? He opens the five-part newbie gift pack: Zhao Gao of the Web takes a whole courtyard to his knees with the Web's network of spies. His two beauties, Ji Zi and Bai Yishu, take different approaches: one works the pleasure districts to make money and connections, while the other opens a cosmetics shop to infiltrate the households of the powerful. The general card gives him Wu Qi, and the civil official card gives him Xun Yu. Wu Qi clasps his fists. “This subordinate will train the troops. Five thousand private soldiers will be ready for battle within the month.” Xun Yu bows. “I shall organize documents for my lord and await the winds of change.” Li Qing surveys the courtyard full of top talent and falls into thought. Just then, a secret report arrives from the Web: the Xiongnu chanyu Qiertie has rallied 500,000 cavalry to march south and intends to flatten Wuguan Pass. Li Qing rises, dons his armor, and takes up his halberd. “The System may be sixteen years late. It doesn't matter. I've been ready for this all along.”
