The food on the King Lu Mountain should be sufficient to last for a while. Therefore, the food supply for the Wei Wu Army should be sufficient.
The Wei Wu Army knew the condition of their food supply. They were originally planning to ration their food for a month but their King found a new source of food.
At this moment, Li Heitan, who was supposed to be training, suddenly ran back to the King Lu Mountain and yelled at the entrance of the cave, "King, a group of the Black Feather Army entered the mountain!"
Lu Shu walked out from the cave. "They came so quickly? Which direction are they heading to?"
"They are not targeting us," said Li Heitan, "they seem to be going to the back of the Wei Bei Pass!"
