The Spartan War God Returns

Legendary Spartan general Agis, betrayed and killed by his brother Damocles, reincarnates in his frail 14-year-old brother-in-law Areus. He fights in gladiatorial arenas to protect his widow Selene and avenge his kingdom, defeating invaders with his ultimate skill before abruptly waking back in his original era.

It runs 59 short episodes on MicroDrama and leans on revenge tropes, with each episode ending on a hook.

The draw here is the slow build to a payback that lands hard.

At roughly 1–2 hours in total, it's quicker to finish than most full-length series.
