What Zhang Chi saw was only the surface.
But what Gu Youyou saw was entirely different from Zhang Chi.
She saw the Great Dao appear and disappear within the opening and closing cracks, cycling endlessly, turning over and over again.
Just one glimpse had her immersed in it, as if she could hear the sounds of the Great Dao in her ears.
"...The valley spirit dies not, it is called the Mysterious Female, the door of the Mysterious Female..."
Gu Youyou murmured the sounds of the Great Dao she heard, her eyes devoid of spirit, as if in a trance.
Zhang Chi was immediately shocked, weren't these words from the Tao Te Ching?
As a modern person, reciting the entire Tao Te Ching was difficult for him, but he was familiar with several of the more famous phrases.
So as soon as Gu Youyou spoke, Zhang Chi identified it as coming from the Tao Te Ching.
When Zhang Chi was a lawyer, he had not read much of the Buddhist and Daoist scriptures, after all, he was just a lawyer, not a sorcerer.
