For the first challenge of the Caventry's Main Trials, Sato was to reach the designated spot on the [Staircase of Zolstice] within 48 hours.
During his entire adventure with 'Xue Yan', though it seemed short, Sato had actually spent more than 8 hours of which a majority was spent within the cavern. Now it was almost 12 hours since Sato had walked up the mountain but he was still a bit far from reaching the red stripe on the mountain.
"Huff, Huff, Huff."
Sato dragged his weary body up the mountain. He had been hiking for slightly more than 4 hours now and along the way, Sato had to face a diversity of monsters.
