Song of Exile

In the winter of the first year of Baoying, when Taibai was in the sky, red lotus and white lotus appeared in Taiye Pond with their stems blooming against the season. The prophecy said: red lotus will cause fire, and the immortal will be banished as a sacrifice. All signs seemed to point to the banished immortal wandering the world, but his old friends and acquaintances were waiting for the news of his death. At the same time, Emperor Daizong issued a decree asking his relatives and friends to return to Shu with his coffin. What would happen along the way? Banishing immortals, banishing immortals, are they humans or immortals? How much do you know about his story?
