In a valley not far north of Kaoshan City, Gui Lian'er led Chu Liang and a group of their followers to the ground.
He turned around, and spoke in a grave tone, "The imperial court's people will set off from Kaoshan City. They can see this place no matter which direction they go, so let's intercept them here. You wait here. Later, I will conjure a magic fog, which will obstruct divine sense and hide the valley. Those from the imperial court in the air will absolutely not detect even a trace of our presence. Once the White Feathered Golden Luan Bird appears, we will immediately launch our attack!"
Having said that, he brandished a large flag in the air, muttering words under his breath, before shouting loudly after a moment, "Fog, arise!"
Whooosh--
Sure enough, dense grey fog rose abruptly from the flat ground, quickly enveloping the entire valley and completely concealing everyone.
Everyone was watching the sky in secret.
