All the People Become Suzerains? I Was the Only One Who Signed in at the Beginning!

[Decisive killing + upgrade flow + cool writing + single female protagonist + all worlds] [Five billion people around the world traveled through time and became suzerains. [The 5 billion suzerains are divided into 50,000 local areas, each with 100,000 suzerains. [You can open six interfaces: "Personal Information", "Sect Leader's Task", "Disciple Information", "Regional Chat", "Regional Transaction" and "Sect Competition". [In this world, cultivate disciples to your heart's content, improve yourself, and survive! [You get the experience sign-in system, and sign-in at the beginning costs 1,000 experience. Of the 5 billion people, I am the only one who can sign in. As the saying goes, one step is faster and each step is faster, the gap between them and me will only become wider and wider. I will eventually become the emperor!
