Mountain Eagle had Crow as his eyes, so he could clearly see his location, and with the presence of Golden Cicada, he could have complete battlefield awareness.
However, this ability wasn't very effective on static objects, like what was in front of him...
Robbin showed Mountain Eagle a scene of a drug dealer disposing of a corpse...
Four large Oil Barrels equipped with blowers lined up, next to a conspicuous 5-meter by 5-meter square pit dug out by an excavator.
Mountain Eagle didn't know how deep the pit was, but he saw it was now filled with charred bones.
Yes, bones...
Mountain Eagle had seen this place before, but he initially just swept his eyes over it, without closely observing the area without human activity. He thought it was a place in the Farm where garbage was burned or meals were cooked.
What he never expected was that this was an actual site where Los Zetas disposed of bodies.
