A World Where Everyone Cultivates Immortality

The nurses here can draw talismans in midair to reduce inflammation and ease pain. With a wave of the hand, a flying-sword taxi pulls up, and for just twenty yuan, you can ride a dragon bus. Everyone also receives compulsory education in immortal cultivation. In such a prosperous cultivation world, why is the highest realm only the Nascent Soul stage? It turns out cultivation theory hasn't kept up. Could industrial compressors be used to increase the density of spiritual energy? Could close-in weapon systems intercept flying-sword attacks? Could silver iodide shells trigger artificial rain in advance and dissipate tribulation clouds? So cultivating immortality can actually be quite simple.
