Record of Cultivating Immortality to Fulfill a Last Wish

People cultivate immortality for spiritual roots, cultivation techniques, and chance encounters. But what Xu Zhou cultivates is, regret. When someone dies with an unresolved fixation, they leave a wisp of “regret” behind in the mortal world. He helps a sword cultivator win a duel that ended without a victor, and gains a trace of true insight into the sword path. He helps an alchemist create the spirit pill they never managed to make in their lifetime, and gains a hundred years of cultivation. He helps a mortal find the daughter she lost many years ago, and gains a thread of golden merit. One unfulfilled wish after another, one stubborn fixation after another, sets a boy of mediocre talent on a path to immortality no one has ever walked before.
