The Government Issues Wives, Four in One Batch

Suddenly traveled to ancient times, what? This is a feminist country, but I have to be delegated to be someone else's husband. Isn't this just a disguised form of getting wives, and getting four wives at once, all of them are as beautiful as flowers, and they also want to have children as soon as possible? What? Foreigners invade again... It doesn't matter. With what I learned in my previous life, I won't be afraid even if I travel all over the world. Prairie cavalry, strange talk about the unstoppable art of war? Are the Japanese pirates' soldiers invincible? Joke!
