On a macro level, Ji Xinghe's emaciated body rapidly restored itself to a robust fullness. On a micro level, Ji Xinghe's broken genes, upon receiving sufficient energy that was no longer destructive, began to rapidly repair.
It's like patients whose genes were destroyed by nuclear radiation, whose bodies should have dissolved into an unidentifiable mass of blood and tissue, but were rid of all harmful radiation before the 'dissolving' began. The genetic information guided the body to absorb energy through food and medicine, reconstructing a complete and healthy body.
The energy Ji Xinghe could utilize at this moment far exceeded what humans could acquire through means like eating, and the efficiency of its absorption and use was far greater.
The channel for absorbing sacred crystal energy had not been closed, nor even obviously reduced. But the uncontrolled energy surging from it, once inside Ji Xinghe's body, found a broader space for activity, akin to a living space.
