Tang Qing went to bed very late that night.
On one hand, he couldn't fall asleep and on the other, he kept an eye on the messages sent by his robots. After all, he felt that the robots at the command center should've been rebuilt if they'd only stayed foolishly at the entrance of his uncle's hotel room for the entire night.
The robot bodyguards accomplished three tasks that night.
The first task was to find out Tang Kai's hotel records at the front desk. Tang Qing had no idea how they did it and he didn't want to know either. He simply had a team of experts working behind the scenes, so he really didn't need to worry too much. The records showed that his uncle Tang Kai had checked in three days ago, at eight in the morning.
