All of the servants who were in their room, when they heard the alarm sound, they immediately took out their hidden guns and ran towards the living room.
Little Champ, who was solving his mathematical problems, all of a sudden heard the alarm sound echo throughout the whole penthouse and he immediately got panicked and stood up and hugged Lu Lan tightly.
Even, Lu Lan wasn't able to understand how this alarm sound echoed in the whole penthouse? She didn't know that there was any such system in their penthouse.
'What is that?'
'Who did set this alarm?'
Lu Lan was confused, more of shock because she hadn't seen Little Champ in this panic stage, but she didn't pay attention to the alarm sound because Little Champ was in her arms and he was badly shivering.
Little Champ heard this alarm sound three years back in Juan's villa on his birthday when he had lost his parents.
