"After eating this Sky Fiend Fire Spirit Fruit, my spirit body can certainly improve to the fourth step. It'll be a bit of pity though."
Half step Kings had fourth step spirit bodies, which was the crux to becoming a Half step King. Ye Chen naturally didn't have a fourth step body. Previously, he had raised his spirit body to the third step through the Dragon Blood Grass. For the time being, his spirit body could no longer increase past the mid third step. Since this fruit could raise half a step of Half step King's spirit bodies, it could certainly upgrade his spirit body by one step or close to it.
