This little hill didn't differ much from those one would see in a park, a manicured hillock designed as part of a garden landscape.
It was planted with various trees, had footpaths through the woods, and was interspersed with weeds. Now deep into autumn, many yellowed leaves lay scattered amidst the grass.
In fact, the Underground Building was beneath this very hill. The problem was that its entrance was extremely well-hidden—the door was part of the hillside itself and required a switch to be triggered to open.
When the door was closed, it was utterly indiscernible from the outside world.
Ou Lan and Zhan Lingtao, who had never undergone scouting training, naturally couldn't spot it either, let alone know about the existence of such an Underground Building within Ailan Castle. They were blindly searching.
At present, their sole goal was to scale this modest hillock.
