The incoming force was only a small troop; the fight was hardly challenging. After happily hanging up the phone, Gao Yang said over the radio, "Guys, latest update, our enemy is just a small force. Although we're not yet clear on the exact number, we can be sure they don't have the capability to surround us, so there's no need to widen our reconnaissance. Head back to camp and prepare to move the injured."
Although there wouldn't be any danger, the temporary camp was already compromised, a change in location was definitely needed; it just wasn't urgent.
The rest was just a matter of details: assign people to carry the wounded, take the indispensable items, discard everything that's non-essential. By the time everyone from the lookout posts returned, the preparations for movement would be nearly complete. With just an order, they could leave at any moment.
