Another source?
Qin Heng thought it over and quickly formed a guess.
The source Fu Kong had mentioned was most likely the fingertip region of one of the Supreme Hand's fingers. Since it had been preserved intact, it was relatively sealed off, with hardly any Variant Cell Universes.
The place Purple Leaf had reached, on the other hand, was the broken wrist section of the Supreme Hand. A great deal of supreme treasure blood had once spilled from there, forming a thick scab—the "wall" she had described.
As for why Variant Cell Universes had gathered there in such numbers, it could roughly be understood as an infection beginning at the wound.
In other words, the Variant Cell Universes might be the "decomposers" of the Sacred Realm!
Just like when a living creature died and its corpse lay exposed in the wilderness, gradually rotting away until it finally returned to heaven and earth.
Even a Supreme's undying immortality had its limits. After death had lasted long enough, Variant Cell Universes would emerge—and grow increasingly numerous.
Once the number of such decomposers reached a certain threshold, the Supreme Corpse would be worn away completely, ultimately vanishing from the Eight Thousand Sacred Realms.
It seems our earlier assumption was wrong. Supremes do decrease in number; it's simply that the odds are relatively low, Qin Heng thought.
Dong Huaiyue had also shared his speculation and replied inwardly, Variant Cell Universes decompose Supreme Corpses, while we devour Variant Cell Universes. Through this medium, it is equivalent to devouring the Supreme Corpse itself. It seems there's no need for us to go elsewhere. We can undergo secluded cultivation here and wait for the right time.
They had originally been unable to devour even a trace of energy from a Supreme Corpse, but with Variant Cell Universes
