Rescue Zeus

Hermes, disguised as a shepherd, led a pack of cattle goes towards a cave. He only kept this pack of cattle because it's a trophy of his trick against Apollo, he never expected someday it would be useful.

When reached the suitable distance, he took out a lyre and began to play.

Should I believe in Thanatos and Hypnos? Can this idea really work?

The situation didn't allow him to think more. The serpentess Delphyne rushed out of the cave and roared: "Who dares to disturb my sleep?"

Hermes pretended to be completely afraid: "The great goddess, I didn't know it would trouble you. I just want to test this musical instrument."

Hearing a person call her "great goddess", Delphyne calmed down. Then she was curious: "A new musical instrument? Let me hear it."

Hermes played a melody. Delphyne appreciated: "Human, you have talents. I'll spare your life if you stay here and play music for me every day."

Suddenly, a string was broken. Delphyne surprised: "What happened?"

"I used tendons of a bull to make this instrument, but it isn't durable enough. If I have better material..."

The serpentess ran into the cave and went out with a bunch of tendons: "This is tendons of a god. It should be good enough."

The moment Hermes got the bunch of tendons, he activated the winged shoes under his feet and flew away faster than any wind.

Inside a cave under Mount Haemus, Zeus was imprisoned, sipped the taste of defeat. Suddenly, he heard a footstep.

"Who?"

"It's me." Hypnos walked out of the shadow.

"How can you come here? Where's Echidna?"

"I put her to sleep."

Zeus looked at him from top to toe, then said: "Your divine power is stronger than I thought."

"But I can't make her sleep for long, so let's be quick. I will rescue you..."

Zeus shook his head: "Even if you can take me out of this cave, I'm disabled. Typhoeus will quickly catch up with us."

"If I give you this?" Hypnos took out a bunch of tendons.

Seeing this, Zeus rejoiced: "If you can save me, I will give you a wish as long as it's within the reach of my power."

"Then please make an oath with river Styx."
