After the tasks were allocated, the two squads sprang into action.
One group of experts who stayed behind began to study the structure of the sinkhole more meticulously, using a portable X-ray fluorescence spectrometer to analyze the composition of any potential gold metal fragments, while also employing a portable mass spectrometer to detect chemical substances in the air, hoping to find more clues.
Meanwhile,
another expert, escorted by a special soldier, ventured deep into the heart of the Qinling.
They carefully made their way through the dense forest.
To ensure safety, they also carried non-lethal defense weapons to deal with any potential encounters with wild animals or unidentified organisms.
This was because the terrain deep in Qinling was intrinsically complex.
Even if they were much more capable than ordinary people, they could only achieve a speed of around five kilometers per hour.
They had left the sinkhole near dusk.
