Chen Xuan had a warehouse holding ten billion worth of supplies, so that wasn't a problem. The only catch was that all his wild antics were being livestreamed by a System called the Map of the Realm to Zhu Yuanzhang, the founding emperor of the Ming! [Zhengtong Era] Chen Xuan: "Don't panic, Your Majesty. I can get you out of here with instant noodles and riot shields!" Zhu Qizhen: "???" [Hongwu Era] Zhu Yuanzhang: "Good lad! Find out who this young fellow is! I want him as Grand Marshal!" [Zhengtong Era] Chen Xuan: "The emperor has been captured. The country cannot go a day without a ruler. Prince Cheng should ascend the throne!" The officials: "!!!" [Hongwu Era] Zhu Yuanzhang stamped his feet in anger, then laughed with delight. "Exactly! That's what you should do!
