Solo Leveling anime episode 7 referred to the Elixir of Life, which is inherently linked with the Eternal Slumber. While the latter is a comatose condition, the former is the cure for it.

  • The supernatural sleeping condition known as Eternal Slumber, or Eternal Sleep Disease in the anime, initially surfaced when humanity was made aware that Magic Beasts existed. Because the individuals who acquire this sickness are intolerant to mana, symptoms usually appear after prolonged exposure to a mana-radiating individual.
  • Before completely giving in to the effects of the illness and going into a coma, the sufferer will initially start to pass out against their will for a significantly longer period than usual.
  • This not only causes its victims to lose consciousness permanently, but it also rapidly depletes their life energy.

In all of this chaos, Sung Jinwoo must find a way to escape from these clutches, acquire the Elixir of Life, and defeat the boss at the Demon Castle. Upon defeating Cerberus, Jinwoo is rewarded with a cryptic document that contains the recipe for the elixir, but he must enter the Demon Castle and defeat the boss within to acquire the three secret ingredients that make up the potion. While this is a fairly direct mission and a straightforward solution to his problems, Jinwoo understands and acknowledges his limitations and chooses to retreat for now promising to return in the future.


While discussions surrounding the elixir could’ve been done more extensively, we do not intend to ruin the suspense for the anime fans. There are changes that the Solo Leveling anime has adapted and it deviates from the originality of the manhwa.

Therefore, without the ability to predict what would happen in the future and how certain theories would unfold otherwise, we must refrain from erasing the line between the anime and the manhwa. Lastly, now that the anime has already hinted at the Demon Castle arc, get ready for your favorite hunter to level up like crazy in the upcoming storyline!
