Great Tang: Awakening the Strongest Martial Arts System from the Start

[System + alternate-history setting + lighthearted comedy + 90% invincible]

Just as I make a name for myself in the martial world and prepare to become a great hero, you tell me my father is Li Chengqian, and that he's still alive and planning a rebellion! Ha, someone must be trying to frame me because I'm just too outstanding! What? Li Shimin has announced my true identity to the world and wants to make me Crown Prince? You've got to be kidding! I'm the exalted God of War. Why would I care about your throne? An alternate timeline and world, so don't take it as real history.
