Being only twenty-five years old when he stepped into Tendon Changing, the difficulty for him to later enter the Bone Tempering Realm was substantial, yet Xu Hongyu had already achieved Tendon Changing Perfection. After some trials, it was quite possible for her to step into the Bone Tempering Realm. Although Chen Mu, once he reached Tendon Changing Perfection, relying on his Horizontally Trained Body wouldn't be too far behind a typical Bone Tempering Minor Achievement, but Bone Tempering and Tendon Changing are ultimately two different realms after all.
Moreover, Xu Hongyu was a direct descendant of the Yu Family.
With Chen Mu's innate talent and qualifications, if he were to be betrothed, a woman from a collateral branch would more than suffice; in fact, even a common main branch member would be suitable, like Yu Ru. But Xu Hongyu... that still wouldn't be quite appropriate.
