Salvation was impossible.
Back then, at the [Cell Factory], An Dan had already suffered brain death due to Jiang Lu trembling the earth, that is, his brain, within the inner space.
This results in the current state of An Dan being hard to define.
You would say he's dead, but with the idle AI operations of the [Exorcist System], he actually isn't much different from before. Even under the condition that Jiang Lu never forcefully intervenes with the system, it's possible that the idle AI isn't even aware that it's an AI.
If one's thoughts, abilities, physical conditions, memories, all of everything is the same as An Dan's, how could you say he's not the living An Dan?
But if you say he's still alive, it's clearly unreasonable too.
A cancer patient may not perceive his illness; cancer may not affect his daily life, but this doesn't mean he's healthy. Perhaps one day, this hidden danger will emerge, delivering a severe blow to the patient.
