Nano Machine

Until he became the lowest-ranked master, his lonely and luckless life never changed.
Suddenly one day, a descendant injected him with a nanomachine, and the machine started ‘speaking’ to him.
[I am the seventh generation Nanomachine manufactured by Sky Cooperation, and I am operating as a central nerve connected to your brain.]
“What? What are you talking about?”
This was beyond the boy’s knowledge, he turned pale.
The Nanomachine linked to his cerebrum realized the User was not understanding a single word it said.
“Who are you, and why are you doing this to me?”
[“I am the seventh generation Nanomachine.]
“Nano Machine?”
[Yes, Nanomachine.]
The boy’s face hardened.
Mashin was the deity the Mashin Religion worshipped, along with the Sacred Fire.
The religions’ Master communicated with Mashin.
“Um, are you really Mashin?”
The boy knelt down and asked with a trembling voice. At this, the Nanomachine attached to his cerebrum realized it had been misunderstood.
