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.

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.
