Walkthroughs for custom maps.

Does anyone know of a video walkthrough of the Xiedu scenario completed in 70 days (or however many days it takes)? It seems like some kind of fantasy. I'm most interested in the battle against the orange player with 300 archers, 300 titans, 800 djinn, 900 wizards, and some azure units as a bonus. Essentially, the AI has no useless units. It's one thing when you have 3000 snipers; I even managed to beat it on month 10, and even 3000 would have been enough, but in such a short time, I don't even know what strategy could be used. Richard Chen completed this map relatively quickly, but I couldn't find that particular battle in his playthrough. This is a key battle, as it unlocks the keymaster's tents.
