The battle before the Yabba Craftsmen Treasury started quickly and ended quickly. The entire thing took less than four seconds.
The Level-9 Nagas were quite unfortunate. They were just "scraped" by Link's magic and ended up dead. It was honestly an instant kill. The truly shocking part was the fight between Link and the Legendary Naga. It took two seconds, which didn't seem long, but Link had brushed shoulders with death.
After the battle, Link waved at Elin who was hiding in the darkness to show it was safe. Then he walked towards the fallen Legendary Naga.
She had been hit ten times by Link's whip. Her head was gone and so were her simple clothes, revealing a broken but healthy body. Link obviously wasn't appreciating the Naga's sexy body. He was trying to determine her status.
