The previously cold phone lay in Li Yan's palm but also became warm.
Li Yan was very interested in it and began to inquire and study constantly.
Suddenly, a faint vibration was transmitted to his palm, and unfamiliar numbers were reflected in his dark pupils—
"Hmm?"
A slightly puzzled sound echoed throughout the entire laboratory.
Huang Shou looked at the vibrating phone, his eyes almost popping out, and his voice was full of surprise and excitement, exclaiming, "It's... the big sister calling..."
He was so excited as if he had seen new hope in life...
Li Yan didn't need to think to naturally know that the big sister he mentioned was Gu Tong!
The phone in his hand was still vibrating, and the Devil King, without any guidance, directly pressed the green button.
In an instant, the phone stopped vibrating.
A tentative voice came through the phone—
"Hello..."
