First of all, the Meme's thought infection has no physical existence.
It isn't like a virus, which requires physical cells as the source of infection.
This was also why he and Chu An couldn't determine whether a certain Zombie Meme was the cause of humans turning into Zombies.
The reason was simple. Zombie infection clearly required scratching or biting a human.
If thought infection could take effect, then why was wound infection still necessary?
Although this could be explained by the fear caused by being scratched strengthening the Meme's effects, it still seemed somewhat superfluous.
Moreover, if Rabies Virus was the precursor to the Zombie Virus, then Rabies Virus in reality couldn't be transmitted from human to human.
In other words, the saliva secreted by someone infected with Rabies contained no virus.
A Rabies patient couldn't transmit the virus by biting someone.
This was completely different from the Zombie Virus.
Furthermore, if the Rabies Virus, the precursor to the Zombie Virus, had already existed in the human body—or was, in other words, a part of the human body—then why did it evade the immune system?
It was like returning to your own home yet having to hide from the security guard at the residential compound.
If another question was added to the mix, it was that Rabies Virus would cause the infected person to die automatically.
That was also different from the Zombie Virus.
All these counterexamples instead made the issue increasingly mysterious.
Under Mind Unity, as Lin An pondered these questions, the Second Will suddenly spoke:
("Lin An, your reasoning is wrong.")
("Or rather, both you and Chu An have fallen into a misunderstanding.")
("Why do both of you believe that Zombies are related to the Doomsday Crisis? Can't they exist independently in human history?")
"What!?"
The words escaped
