Tang Luo had a stunned look on his face, not from the effect of the Undying Battle Body, but rather he was taken aback by Ji Fu's words, feeling a bit hesitant.
After all, it's always a bit unbelievable when a habitual cheat gets hit with such a forceful blow of honesty!
"You're saying that the primary thing about training the Undying Battle Body is about control over Spiritual Energy, what do you mean by that?" Tang Luo asked cautiously.
Looking at the other's troubled expression, Ji Fu responded proudly, "Each Spirit mark is incredibly difficult to engrave, especially after activating the Undying Battle Body. The Spirit marks reveal your body's unconscious movement of Spiritual Power, and trying to control it is even harder. Even Saint Han with his exceptional Earth Spirit Body managed to engrave only a second-grade Undying Body, a rarity in the world."
