Song Yaoyao pointed in the direction she had just returned from and said,
"The reason I came back late was that I discovered a coal deposit up ahead. I dismounted to take a look, which delayed me a little."
Chen Yixiao said, "Little Lord Song, take us to see the coal deposit."
Song Yaoyao said, "No problem."

Song Yaoyao said, "Yes."

Even Heaven is lending us a hand..."
After his laughter subsided, Maternal Grandfather Ning said to Ning
