Looking for Stories Where Crown Princes From Different Dynasties Gather Together, Like on the Cover

You know, stories where Fusu, Liu Ju, Li Chengqian, and others end up in another world. (The book in the cover image turns Zhu Biao into Zhu Di.) There's also a great fic on Lofter called Spring Harmony and Bright Scenery, which is wonderful too. There's never enough to read. No CP, no CP, no CP, no CP.
