Ye Han had his reasons for asking that question, of course. Across the Myriad Realms, any rare and unusual circumstance could exist or arise.
Cold Moon Immortal having two nascent souls was indeed exceedingly rare, but that did not mean it was impossible...
Among the books Ye Han had read, there had only been one or two similar accounts, but the circumstances had been rather unusual. A cultivator had possessed two physical bodies, both of them his true bodies. After an extraordinary incident in which he took possession of another cultivator's body, the nascent soul inside his original body had actually split off another nascent soul...
Strictly speaking, it had still been one nascent soul, only split into two for a peculiar reason.
But during his subsequent cultivation, he had cultivated the nascent souls in those two bodies separately, eventually producing two bodies with two nascent souls. This had greatly increased his cultivation and divine abilities, and tales of that powerful cultivator had spread widely throughout the Cultivation World.
Such circumstances were truly far too rare. Among billions upon billions of cultivators, there was only this one recorded exceptional case. Of course, the Myriad Realms were so vast that Ye Han might not know of every such unusual case.
Still, it was already a highly representative example!
Yet he discovered that Cold Moon Immortal's situation was entirely different from the recorded case. She had only one physical body, but two nascent souls, and both were extremely unusual. One was like Cold Moon Immortal herself, pure to the utmost...
The other was somewhat more complicated. Aside from carrying an aura of grim slaughter, it also gave him a very familiar feeling. The overall impression was exceedingly strange, as though it shared something with the aura of Nethergod Devil Lord's spell power.
