Lu Gan's face turned gloomy.
"I've investigated Qi Yuchuan's mother. She and your father graduated from the same university. They should have known each other before your parents got married. Also, some of her past has been deliberately erased."
Lu Gan frowned. Qi Yuchuan was older than Lu Gan but younger than Lu Heng. This meant Lu Hongyong had an affair!
The private investigator said, "There's something else I've discovered."
"What is it?"
"If I'm not mistaken, your brother has also investigated Qi Yuchuan."
Lu Gan suddenly remembered the quarrel between Lu Heng and Lu Hongyong.
At that time, Lu Hongyong was furious.
"You'd better not let Lu Gan know about this!"
Lu Heng slammed the door and walked out. It was then he bumped into Lu Gan. Everything happened so suddenly, so he did not have time to hide the shock on his face.
'Is that why Lu Heng was so angry?'
