How did Brother Bing know about Shenjiu's past?

Brother Bing led the spirit of God Nine to know the past of God Nine. According to Baidu data, the original text is written like this: Luo gradually learned about the past of Shenjiu, and even knew why he didn't pick up Shenjiu later. Somehow, Mr. Luo felt that Shen Jiu was somewhat similar to his own experience and seemed a little sympathetic, which made him very unhappy. However. Another big problem has arisen. He doesn't know how to guide the spiritual knowledge of Shenjiu. Just as Brother Bing was thinking, another cloud floated up, and he saw a small corner squatting in the childhood God Nine.
