At the end of the Emperors Era, the Black Dragon King killed Immortal Emperor Ta Kong and tore the Heaven's Will apart, causing the start of the Difficult Dao Era and the collapse of the bridges between the Nine Worlds. After that no one could visit another world.
The Nine Worlds were finally destroyed due to Li Qiye's War in the World of Death. Their remains shaped the Eight Desolates. Some inhabitants survived the destruction and created long lasting inheritances or lineages.
