Rebuilding Mountains and Rivers: from Vassal King to Eternal Emperor

Should he become a useless vassal king and wait to die, or should he hold a sword and reorganize the world? Look at me, Gongsun Ze, killing traitorous ministers, pacifying the four realms, pacifying the people, launching a new government, and creating an iron-blooded empire: I want this throne; I will save this world!
