It could be confirmed that after being imprisoned in the underworld for thousands of years, enduring both loneliness and the decline of their divine power, Hera and Tyr's resentment towards Hades had reached an immeasurable level.
If John could rescue Hera and Tyr, he might be able to use their hands to eliminate Hades!
Thinking of this, John suddenly smiled.
"What am I thinking? Even if I rescue Hera and Tyr, they might not be willing to face Hades again. Besides, with their divine power weakened, it's uncertain if they could even be a match for Hades."
In any case, completing the main quest to kill Hades was almost impossible.
John didn't have the strength or the courage for it.
If a deity were to fall because of John, he had no doubt that by tomorrow, his existence would be erased.
So, the only optional quest left was to kill the dragon of the underworld.
