"Yue'er, be careful!"
Li Qingmu also noticed it and hurriedly followed Long Yue outside.
Outside, Long Yue was already engaging with the man in black. The opponent's martial arts were quite good, surprisingly matching Long Yue blow for blow. Li Qingmu hurriedly joined the fight.
With Li Qingmu's support, the man was quickly subdued.
At this moment, the opponent attempted to bite his tongue to commit suicide, but Long Yue swiftly dislocated his jaw.
"This person is probably an enemy spy; hand him over to my grandfather!"
Li Qingmu's intuition was spot on; he had worried about enemy infiltration, and indeed, it happened.
Afterward, they escorted the captured enemy soldier to Cao Yin.
Cao Yin was on the city wall directing the defense. Seeing Long Yue escorting a stranger over, he immediately became alert.
"Who is this person?"
