The courtyard of the willow sheng song, the sister swing among the flowers
Legend has it that a long time ago, after Kuafu chased the sun and Nuwa made up for the sky, the sky suddenly fell with stars, forming a bridge at the end of heaven and earth, so that the sky and the world were connected together, but in order to prevent the mortal monster cholera from ascending to heaven and becoming an immortal, Nuwa built four Tianshan Mountains between the floating clouds on the side of the overpass, and then let the four powerful cactus take charge respectively, Long Yin on the cactus to manage the Despair Mountain, Nangong Le on the cactus to manage the delusion mountain, Muzi on the cactus to manage Qingyun Mountain, Yizhang on the cactus to manage Anyi Mountain, In addition, Nuwa also set up two cylindrical pillars of coiling dragons on the side of the overpass, which were
written on them: "Nuo wants to become an immortal"
and "Tianshan cultivation", which means that no matter whether you are a mortal or a monster, as long as you want to cross the overpass and become an immortal, you must cultivate on this Tianshan Mountain, or defeat these four immortals, and you must break off the seven emotions and six desires to become an immortal.
