Ryu's gaze narrowed. There was definitely a secret here, he didn't believe that things were so simple, however it felt like it was entirely beyond even his Dao to see through. It was likely that whatever secret was lying in wait here was too profound for his Third Immortal Grade Dao to see through.
This wasn't necessarily a bad thing. After all, if it was so profound, then that meant that the treasures of this Ruin were even beyond what he had assumed them to be. This wasn't a simple Ruin, and the Heavenly Favor associated with it shouldn't be small.
However, what was baffling was that even after several moments, Ryu didn't feel any influx of Heavenly Favor, leaving him frowning.
To him, the use of this Ruin was secondary. The most important thing to him to gathering up Heavenly Favor. In fact, the only reason he was willing to waste a few hours with Mae was because he felt that the reward of this Ruin would be able to offset the time he spent.
