"All right! Look at the sky, we can't make it back home even if we leave now, it will still be the middle of the night. Let's just spend the night here and head back early tomorrow morning."
The young people, hearing the Earl speak as if they were going back, were somewhat reluctant to return so soon; yet the prospect of spending the night in this Peach Blossom Cave was appealing.
The Earl then arranged for the Veteran Hunter to take turns keeping watch at the cave entrance, ensuring no wild beasts could rush in from the outside.
He also used his Magic Wand to cast a beam of light at the entrance of the orchard cave, making the cave invisible from the outside; in reality, the light was nothing but an Illusion Technique.
The Earl did so to prevent a nighttime ambush and to ensure that after their departure the following day, no wild beasts or other people could enter and disturb the contents of the cave or dig up the medicinal herbs from the garden.
