They follow the ninjas to a warehouse in Chinatown.
They break in and beat people up.
Below the warehouse is the Sanctum of the Chinese Magician Yue Lao.
There are stairs leading down, a cavern, water, a bridge, and an elaborate Chinese palace.
They have tea. Lao cures Henry from poison (inflicted on him during the fight) and shows them the waterfront in his magical bowl.
They head for the Waterfront.
