He died suddenly while drawing at the age of thirty, and transformed into a refugee who died of thirst in another world. You can't practice, but you can see the "spiritual energy" flowing like water - the immortals suck the pure water upstream, and the mortals drink the poisonous soup downstream.

He walked into the festering mine carrying his ragged burden. As an engineer, he knows that if water can be purified, so can the world. If you don't cultivate immortality, you don't kneel to gods. An engineer wants to build a way to survive in this cannibalistic world.
