The details
Chapter 1 is adapted across anime episodes 4, 504, 878. The anime spreads this chapter across more than one episode, which is why the episode and chapter numbers drift further apart the longer the series runs.
One Pace re-cuts the anime to follow the manga's pacing, removing filler and padding. This chapter appears in Romance Dawn, the Dawn of an Adventure.
Netflix's live action passes through this chapter in season 1, episode 1, which covers roughly chapters 1–7 in a single hour. That is a span rather than a chapter list on purpose — the show reorders and merges as it goes, so nobody can honestly map it panel for panel.
