The sage Laozi saw the Wordless Heavenly Scripture at that moment. He had already believed Sha Chen's words. Originally, he was half-doubtful because, although Sha Chen's eyes were well masked, Laozi himself was an old hand, shrewd and experienced. He could tell there were some issues with what Sha Chen had said. But then, seeing Sha Chen produce the Wordless Heavenly Scripture, he 'guessed' what had happened and chose to believe.
Sha Chen's eyes flickered somewhat, and there were ripples in his heart, as if he was reluctant to present the Wordless Heavenly Scripture and to honestly explain himself. However, he still had to honestly explain. As expected, now that he had produced the Wordless Heavenly Scripture, everything about Sha Chen seemed normal again. This indicated that Sha Chen had decided to break the pot and spill it all, resolved to come clean.
