Zhu Di: I Sent You on a Voyage West, and You Destroyed Japan?

Yang Jing transmigrated into the Ming Dynasty, and the System's very first mission was actually to destroy Japan! The Yongle Emperor ordered Yang Jing to lead twenty thousand elite troops westward across the seas, but he immediately turned the ships around: target, Japan! Yang Jing completely let loose, exchanging for large quantities of modern weapons in the shop: Gatling guns with unlimited ammunition, rocket launchers that were excellent for besieging cities, cheap and rugged AK-47s... Before overwhelming firepower, all schemes were futile. He advanced like a hot knife through butter and captured Kyoto in Japan. The emperor? The shogun? All of you are going to dig mines for me! The news reached the Ming Dynasty. The Yongle Emperor: "Did I not tell you to sail westward across the seas? How did you end up destroying Japan?" Yang Jing: "Old Zhu, how about we make a deal? You provide the people, I provide the weapons and technology, and together we will build an empire on which the sun never sets!"
