In My Rebirth, I Want to Lead the Army and Become the Emperor

A crazy critic, how to use modern thinking to completely smash the feudal society. See how the emperor, the nobles of the aristocratic families, and the bullies of the country squires kneel and sing: The east is red, the sun is rising. I traveled through time and became a good-for-nothing prince, and I went crazy to straighten out my affairs. [Grandpa, God of War, only has one year left, and everyone in the dynasty is waiting for my death] I traveled through the town to become the useless grandson of the king's palace. My grandfather was dying, and everyone in the court wanted to send me on my way. Okay, then I will go crazy first to respect you! Gambling in the casino? I'll destroy your place and steal your money! The champion scolded me? I spat on his face! The emperor granted marriage to the eldest princess? I directly tied up the consort candidate and broke his legs! Everyone thought I was a complete lunatic, but I secretly built the strongest "Shuofeng Camp". Until the night when my grandfather passed away, a hundred thousand troops besieged Kyoto. The emperor sneered: "Yue Zheng, your death has come!" I slowly raised the steel knife and pointed it at the dragon throne: "Your Majesty, do you think I will kill the king today because of my madness?"
