[Native-Born Local] [Hundred Schools of Thought] [Political Intrigue] [Wuxia and the Jianghu] [Age of Exploration]
PS: The early part may be somewhat oppressive and slow-paced, but the later part is pure wish fulfillment.
An unfavored prince is assassinated from the start, then turns around and builds a secret intelligence force to rule the world.
The emperor watches coldly from the sidelines, his brothers kick him when he's down, and even the Ministry of Justice treats him as a dead man.
That is, until the secret intelligence force is fully established.
Emperor: "Ninth Son, you're not going to rebel against me, are you?"
Crown Prince: "Ninth Brother, you're not going to pull a Xuanwu Gate on me, are you?"
The tribes of the grasslands: "Ninth Prince is the sun in our hearts!"
The nations of the West: "Please don't hit me, Daddy!"
