One Word Reaches Heaven

One day, iron trees bloom, and spring shoots sprout in winter.

One year, the great river flows backward, and white crows fill the sky.

In one lifetime, good and evil are indistinguishable, and every step is perilous.

One person, with just a single word, laughs above all under heaven.

He says that Heaven has nine layers and Earth eight wilds. I will vie for supremacy across seven realms, and seek no shelter among the six paths. I once seized another's grain, and I once roamed the four seas, championing the weak. Three lifetimes of love have ended, and across two lives I became an immortal. All I wish is for one word to reach Heaven!
