"This is a Bug Whistle, used to control insects."
Zhong Jing Shan said succinctly.
The Bug Whistle was shaped like a trumpet, thin at the top and wide at the bottom, with light runes painted on its black-green shell. Its sound was as crisp and peculiar as that of insects and birds.
Lu Xuan learned from the charm paper given by the man in black robe that the Bug Whistle was a magic artifact to control insects, which could mimic the cries of many Insect Beasts and help cultivators to control various strange insects better.
The Bug Whistle given to him by Zhong Jing Shan still bore his spiritual power aura, exerting a strong deterrent effect on the strange insects he bred in the Insect Valley.
"I am leaving you in charge of things here."
The young man in the black robe nodded to Lu Xuan, tossed him a storage bag, and then, the black robe on his body shone with countless thin black lines that buzzed and turned into a streak of black light that disappeared into the horizon.
