The mining puppets worked tirelessly, carving out a concealed chamber adjacent to one of the larger underground currents. The space was expanded slowly, its structure reinforced with formations to prevent collapse while maintaining the illusion of natural terrain.
Han Yu personally inspected it.
Adjusted it.
Refined it.
Once the space was ready, he added additional layers.
Formation arrays.
Subtle.
Hidden.
Designed to slow the flow of water just enough to reduce impact without drawing attention. Alongside this, he constructed a net mechanism, anchored securely within the chamber. It was not visible at first glance, but once activated, it would catch anything carried by the current.
Including people.
Han Yu stood within that chamber one day, observing the finished structure.
The water flowed steadily nearby.
The formations pulsed faintly.
The net remained hidden.
It was ready.
Mostly.
There were still risks.
Many of them.
