It's really only Tang Luo's fault, after unlocking the Undying Battle Body's top fifth-ranked Divine Storage, he obtained the divine ability Yin-Yang Grinding.
This ability, which allows the fusion of the physical body with Spiritual Power, made Tang Luo almost forget about the task of Spirit Qualifying his body, as he focused solely on strengthening his physical form. By the time he was at the peak of the Fierce Realm and ready to Spirit Qualify his body, he was caught off guard.
Yin-Yang Grinding can indeed help Spirit Qualify the body, but as a divine ability, it also needs to be driven by Spiritual Power.
Common uses such as external release and retraction, trapping, and shattering a soul for combating spirit bodies are manageable, but to refine the body, its energy consumption is dozens to hundreds of times greater than that of exterminating spirit bodies.
