Late-night calls always carried a spine-chilling eeriness.
Especially at such a critical moment.
Everyone halted in their tracks, lifting their gazes toward Si Mo.
Si Mo pulled out his phone and saw another unfamiliar international long-distance number.
He answered the call, "Hello?"
There was a peaceful silence on the line.
Si Mo furrowed his brows and pulled the phone away from his ear to check it again, confirming the call was still connected.
"Hello? Who is this?" Si Mo asked once more.
Just as he finished speaking, a familiar sound suddenly came through the phone: Si Yi's babble.
Although Si Yi was a genius baby, he was still an infant; when he was full and content, he would make squealing and babbling sounds, much like talking.
Si Mo's body went rigid, all traces of drowsiness and sleepiness instantly vanishing.
As he swiftly walked toward the tracking system, he asked in a deep voice, "Who is this?"
It was Si Yi's voice!
