From the start, he falls into Princess Changle's bath? Amid swirling steam and screams throughout the palace, he binds to a fortune System.
Li Shimin, the mighty Khan of Heaven! The strongest carbon-based life-form of the seventh century has just assembled his troops, ready to smash the Turks and avenge the humiliation at the Wei River, when a big shot shows up in his palace!
It's a dragon, a three-hundred-zhang golden dragon! Could the legendary divine dragon really exist?
Doesn't that prove I'm the true Son of Heaven? I want to ride the dragon and tour the Tang Dynasty!
But when the golden dragon takes Li Shimin's imperial throne, then his Ganlu Hall... Li Shimin doesn't dare utter a single word of protest.

Li Shimin is dumbfounded and nearly in tears. "Divine Dragon, you never said there were gods in other places too?!"
The sea, you are all water

A mess

Contrary to history
Good looking, support the author
