2.04 AM.
The air in the mountainous range was cool and fresh, as the summer heat gradually dissipated with the arrival of beautiful autumn. It was the time when everyone let down their guard the most, their eyelids heavy with drowsiness. The dogs were dozing off. Even the patrolling guards were chatting leisurely with each other as they made their rounds with rifles loosely held in their arms.
Nobody knew that the building had long been surrounded from all sides.
Perched on a sturdy tree branch, a man peered through the telescope and confirmed that everything was in place. He tapped his earpiece twice.
On the side of the building, another man was stationed in front of the power box, the body of a patrolling guard sprawled beneath his feet. As soon as he received the signal, he immediately worked to disconnect the power source and the next moment, the electric fence let out a faint hiss and turned off with a snap.
