In that year when the world was in turmoil, I tried my best to save my brother who was seriously ill. I put aside my false identity as a rich man, and threw away all escape options and thoughts. I devoted myself to staying by his side and taking good care of him. This stay lasted for forty years. From black hair to white hair, his temples were gradually stained with frost, and he was getting old. Before he died, he coughed up blood and used his last strength to beg me, "Azhi, if there is an afterlife, leave my chance to live to Ran Ran." He looked at me, his eyes filled with guilt, and he kept mumbling that the only debt he owed in this life was to Ran Ran.
