Wang Chongyang was a sneaky bastard.
He promoted the unification of the three religions and fused the core ideology of Buddhism, Confucianism, and Taoism into one, which was flexible and malleable enough to fit into the political framework. It was exactly as what He He had been told in the "primary ten true precepts": be loyal, be filial, obey your lord and your parents.
No ruler of any era or dynasty would reject such an ideology. Hence, after a period of suppressing religions, the country was making Quanzhen the orthodoxy again, offering the sect a high degree of freedom at the same time.
Zhengyi received no such favor. Even their Celestial Master was appointed by the government.
Gu Yu and Xiaozhai sat in the living room when a gaunt old priest entered. He was of average height and they could tell that he had been practicing Qi-nourishing methods. But probably because of the burden of common affairs on a daily basis, his cultivation level was far below that of Zhang Shouyang.
