Invincibility Is Not Directed Against Anyone

I'd better wait 1,000 years for development first. Isn't it enough to wait for 1,000 years? Or should I develop for 10,000 years? How about being a transparent person during this period? Or find a hole to crawl in and develop obscenely? I decide when to be invincible and when to go out.
