Is It Reasonable for You, the Prince, to Station Millions of Troops When You Are in Despair?

[Avatar history + Dead city on the border + Decisive killing + Invincible cool writing + Developing power] Lu Chen traveled through the Dajing Dynasty and became a downcast prince. The fiefdom is barren and surrounded by enemies. At the beginning, the court ran out of food and the soldiers under his command mutinied! In desperate times, activate the system to enrich the people and strengthen the country! The more people in the fief, the more points you get every day. Points can unlock various military supplies, guns... Lu Chen defeated the rebellion with one shot and established his authority, and then killed corrupt officials angrily. He said coldly: "When the law became a tool for the powerful to oppress the people! I, the king, abolished it with my own hands!" He made the fiefdom rich and prosperous, but the imperial court starved to death thousands of miles away! The Tatar invaders were crushed by modern weapons. He also worked hard to get a few red cannons and laughed: "Lu Chen, do you have the red cannon? Let's see if you die this time!" Lu Chen sneered: "I'm sorry, I don't like that rag, but there are dozens of howitzers!" Two years later, Lu Chen's tanks crushed the ground and planes flew into the sky... The officials asked coldly: "Is it reasonable for you, a vassal king, to station millions of troops?" Lu Chen raised his eyes indifferently: "Why do I need to explain my actions?" The emperor cursed loudly: "Do you still have ancestral system in your eyes?" Lu Chen said loudly: "Only the weak tell the rules, the strong make the rules!" From then on, everything the sun and moon shine on is my soil! Wherever the military front arrives, all nations will bow their heads, and all the world will be vassal!
