As they drive further into the mountains Seo Jun notices what appears to be coffins hanging on the side of the cliffs.
"Are those what I think they are?" Seo Jun asks the driver.
"Yes no one knows why they were out there but you will see them all about. Archeologists have been studying them for awhile now. "The driver tells them.
"I wonder why they are there and what meaning they have. Seo Jun thinks to himself as he sees the coffins that line a mountain side to the right.
"We will be arriving soon, is there anywhere you would like to stop beforehand?" The driver asks.
"No just take us to the town please." Seo Jun answers distracted by the landscape.
They cross a bridge over a large river heading up the mountain. Along the river there are cliff walls that can only be reached by boat. Seo Jun sees a cluster of caves that have the hanging coffins nearby.
