Su Bei had left the Tang family for more than 21 years.
It wasn't a secret that the Tang family had lost a child back then, and many people knew about it. Now that Su Bei had made an appearance, the entire family didn't mention anything. It was easy for Lu Hang to investigate this and it was a quick job too.
However, this matter wasn't publicized yet.
Therefore, everyone in the Tang family knew about it while only Su Bei was kept in the dark.
Lu Heting flipped through the information again and thought to himself, "Old Master Tang came to look for Su Bei in private and even disguised himself. Could it be that he wants to test Su Bei's character?"
Other than that, Lu Heting couldn't think of any other possibility.
At the thought of this, he frowned and slammed the documents on the table.
Lu Hang was scared out of his wits. "M-Mr. Lu, which part of the investigation isn't complete? I'll look into it again!"
