Of course, it was a minute later did they realize they weren't actually alone in there. As they were training, Cao Haoran suddenly realized someone else's eyes were boring onto his back, making him straighten his spine and he instantly turned around, throwing a piece of leaf toward that direction.
He used martial arts to throw that leaf in that place, behind the bushes, specifically above a branch covered with a bunch of leaves. It was impossible to look at who was standing or hiding there from naked eyes, but the third prince's aim was right on the spot as a voice echoed from there laced with traces of arrogance, "Tsk. Tsk. You're still as sharp as ever."
A young man with long, bright red hair jumped down from that branch, holding that leaf. He looked at the third prince with a trace of disappointment in his eyes. "You weren't aiming to kill. Third brother, you've softened."
