Out of respect for social interaction, Shen Xinzi had refrained from using his divine sense, so he was unaware of the content of the book in Gu An's hands. Even when Gu An refused him, he did not entertain any impolite thoughts.
He inquired why, and Gu An replied that Buddhism Sect did not deem it suitable to read secular books, and then he handed Shen Xinzi a copy of "Righteous Path and Demon Path."
"Righteous Path and Demon Path" told the story of how Sword Venerable Fudao inscribed the characters for 'righteous path' at the Heavenly Repair Platform, revealing the dark secrets of the Supreme Sect. Instead of tarnishing the Supreme Sect's reputation, the book made more people aware of the Sect's pursuit of righteousness, encouraging them to actively correct their errors.
Although the book was not as popular as "Journey to the West" or "Investiture of the Gods," many within the sects still favored it, studying it repeatedly.
