[Every rebirth, the 'I' is different, the Mind frequency undergoes subtle changes. The intensity of this Anomaly called [Ghost] is too high, only a completely compatible 'I' can successfully take over.]
[And 'I' am a unique existence in the world.]
[This means we need a million times, ten million times, or even a hundred million times of death and rebirth to barely succeed once.]
Lu Yuan took a deep breath.
This explanation was a bit convoluted, but he understood it nonetheless.
Simply put, 'I' represents self-consciousness, represents the soul.
With every rebirth of the [Demon], self-consciousness undergoes subtle changes.
If a 'self-consciousness' happens to align with the frequency of the [Ghost], then it can succeed, like playing a lottery and suddenly hitting the jackpot.
Otherwise, it will continuously fail, requiring constant suicide to replace the 'self-consciousness'.
