The eerie and piercing trill came from the wooden box that Gongsun Yibo was holding in his hand.
At this moment, he was pacing around Song Qing, his eyes striking with excitement, and his normally serious and hearty demeanor nowhere to be seen.
Well into his adulthood, the Gongsun Family Head was looking at Song Qing with immense excitement, just like an overjoyed child who had just acquired a new toy.
His pupils were noticeably larger than under normal circumstances. Such a change could only be triggered by a state of extreme excitement.
His complexion slightly reddened, a subtle change yet noticeable to the observant viewer.
His breathing became slightly heavier, with the hand holding the box trembling slightly.
From all his expressions and actions, it was clear that Gongsun Yibo was genuinely interested in Song Qing.
The way he was looking at her suggested that to him, she was...a priceless treasure.
