What does the goddess mean by texting me "floating life on the island of death"?

Wu Yu: The Prince of Yan erected a monument to let the world know that Emperor Wen Jian set himself on fire, but no one knows where his grave is. At the end of the Ming Dynasty, Emperor Chongzhen once said that he would pay a visit, but he didn't know where it was. Another way of saying it is to break the floating life in Nanjing: an empty life. On the whole, it should be a fantasy without a goal.
