After waiting for a while longer, Xiao Jie transformed into a transparent flying insect again, sticking close to the palace's walls and the shadows of the columns, starting to fly low to explore, trying to avoid being exposed in open areas.
He first aimed at the nearest palace group below that looked quite magnificent. The insect body descended lightly, wanting to fly directly into some open window or balcony from mid-air.
However, as soon as he descended to about ten meters from the palace roof—
Buzz!
An invisible yet resilient huge force appeared out of nowhere, as if crashing into an unseen gel wall! No matter how he flapped his wings, he couldn't descend any further.
"Huh? An air wall?" Xiao Jie was stunned, then quickly realized, "No, it's a Barrier! A protective Immortal Barrier!"
