Chu Hongnan indeed isn't much.
But Jing Yan beside Chu Hongnan is truly terrifying. They all knew that Jing Yan was Chu Hongnan's grandson. Although from Jing Yan's attitude toward Chu Hongnan, it could be seen that Jing Yan and Chu Hongnan weren't very close, as he directly called him Chu Clan Leader.
But the two of Sheng Jing still didn't dare to show any contempt toward Chu Hongnan. Even if they elevated themselves high, with Chu Hongnan and Jing Yan having a rift, Jing Yan would still only have a negative impression of them.
The two of Sheng Jing also knew that with someone like Jing Yan backing them, it would be hard for the Chu family not to thrive. They could foresee that within the Five Great Divine Regions, the Chu family would become increasingly powerful, and in a few hundred to a thousand years, even without relying on Jing Yan, they would be able to compare with their two first-grade forces.
