Im Sobaek arrived at the rear garden and took a deep breath.

“The night air is nice.”

I also breathed in the night air deeply. It was a cool evening, perfect for a walk. We passed through the rear garden and followed a narrow path, as if heading toward the mountain behind.

At this depth, they must have excavated the mountain to create the hollow.

Soon, we reached a dead-end wall covered in vines, and there, Im Sobaek casually lifted the sword at his waist and pushed it into a specific section.

The vine-covered wall shifted and moved aside, revealing a narrow space just wide enough to enter.

As we stepped into the vault, the smell of dust pricked my nose—it was quite dark inside.
