Da Zui: Your Majesty, Calm Down, I Don't Want to Ascend the Throne Yet

[This book has been greatly revised. I was locked up in a small dark room. I don't know what went wrong, so I simply rewrote it] Li Xiao traveled to Daqian and became the deposed prince of the current dynasty. He originally wanted to live in peace, but unexpectedly he awakened to the Wanjie Sales System. As long as he has enough money, he can buy anything in the system. Electric energy pulse gun? Buy one for self-defense. Plasma Shield Plus version? Buy a self-defense. Gundam? Men's favorite, I must buy one. Accidentally, he formed his own mecha army. Emperor Daqian couldn't sit still and gave in overnight. The emperor of the enemy country could no longer sit still and issued an order overnight to surrender and become a vassal state. The most uneasy ones are the Western Monster Tribe: It's over, our spells have almost no effect on these behemoths.
