In the malformed and twisted underground cave, the howling of mechanical hunting dogs echoed.
They followed a familiar scent, winding through the maze-like cave, arriving at the underground riverbank.
Along the way, every 1.2 kilometers on average, a drop of Qing Chen's blood appeared.
A total of 37 drops, spreading all the way to the deepest part of the cave.
Ordinary excellent hunting dogs have a tracking distance of 0.5 kilometers, while mechanical hunting dogs have a maximum tracking distance of 1.3 kilometers.
Therefore, Qing Chen's blood appearing every 1.2 kilometers, very consistently, suggests that Qing Chen intentionally left these traces, hoping that reinforcements could catch up based on them.
This discovery excited everyone, as it meant Qing Chen was still conscious, even when gravely injured and at the end of his strength, still finding ways to save himself.
Their biggest fear was that Qing Chen had already collapsed.
