The earth immortal who has been squatting in the barren ravine for three hundred years has not yet warmed up, but the sound of the hooves of the green cattle first broke through the morning mist. All the passers-by opened the wine jar and sniffed it, then slapped their legs and said they were convinced. Later, they even rode oxen to drink the wine every two days. I called him Xiaotongtong and he responded with a smile, and smoothly promoted me from the earthly immortal to the peak of the heavenly immortal. After drinking the third bottle that day, he wiped the wine stains from his beard and said, "Tell the truth, my name is Tongtian."
