The ninth level of the Undying Sword Body could withstand the attacks of high-level Super Supremes, while the tenth level could withstand the attacks of Peak Super Supremes. In the entire Human Race, aside from Golden Buddha Supreme, no one possessed a stronger physical defense than Ye Chen. However, it was said that the long-missing Golden Supreme of the Dragon Clan had surpassed even Golden Buddha Supreme in body refinement achievements.
Of course, Golden Buddha Supreme and Golden Supreme both possessed Ninth-Order Spirit Physiques. Even a select few Supremes, such as True Martial Supreme and Bronze Supreme, possessed Ninth-Order Spirit Physiques. If Ye Chen could raise his Spirit Body to the ninth order, then the tenth level of the Undying Sword Body would not merely contend with the attacks of Peak Supremes—it could even withstand the attacks of Quasi-Legendary Supremes, such as Rotfiend Celestial.
A Ninth-Order Spirit Physique was also known as an Undying Body. Undying Power surged and roiled within it, which was also immensely beneficial to advancing the Undying Sword Body. The two complemented each other.
Therefore, Ye Chen felt it was necessary to raise his Spirit Body to the ninth order.
Unfortunately, Supremes who did not specialize in body refinement could not improve their Spirit Bodies through their own efforts. They could only rely on heavenly treasures. Although a Ninth-Order Spirit Physique forged this way was far inferior to that of a body-refining Supreme, it was still better than having none at all.

High attack, on the other hand, might heavily wound an opponent with weak defenses, but against one with strong defenses, it was equally useless. For instance,
