A Great Quest was a type of quest that concerned the gods, monster lords, spirit gods, or demon gods. It was one of the most difficult quests, as a god-level powerhouse could directly attack.
Some of his quests before also involved gods, but those gods weren't the main focus of the quest. The instruction wasn't against the gods, but here... The Great Quest was primarily focused on god-level beings.
Souta would undoubtedly fight some god-level beings in this quest. Even if he didn't meet Lucifer, those Demon Pillars would chase after him if he went against Lucifer. Demon Pillars were the army commanders of the seventy armies of Heavenly Demon Palace, and each one of them attained the god realm.
But he didn't need to worry about this Great Quest now. He was weak, and he just needed to follow the system's instructions to avoid Lucifer's detection. Plus, he didn't harbor any ill intent towards Lucifer at this moment.
