On the ground.
After Gu Qing Shan and the Emperor left the presidential office.
The group of the President's aides inside the building has already fled.
In a secluded corner.
Whether by coincidence or on purpose, when Gu Qing Shan's sword qi slashed this place, the building and materials from above collapsed and balanced on each other, creating a dead angle when viewed from above.
One of the aides was hiding here.
A tall aide ------the one that brewed tea for Gu Qing Shan and the President from before.
He sat squatted in this dead angle that Gu Qing Shan had created and looked around outside.
Complete silence, no one was there.
The aide then silently laid down and pushed into a certain corner of the wall.
A small hidden hatch was revealed.
The aide then started to crawl inside, closing the hatch as he does.
When the hatch closed, from the outside, it looked like a completely normal corner of a room.
