Xiao Xuan was a clever man.
Everything that happened was apparently a scheme against the Xiao family. To get out of the situation, he had to kill the key person rather than starting a battle between the three families.
Who was the key person?
"Chen Fan," of course!
The Wang family and the Qin family were arranging a marriage because of him and people were mocking Xiao Xuan because of him. Killing or banishing Chen Fan would automatically break the relationship between the Qin family and the Wang family.
"I don't know what is so special about you that makes the Old Lord Wang have your back and the Old Lord Qin agree to let Yaner be your concubine. You might be the heir of some major family elsewhere or might come from a hidden family like the Lin family, but it doesn't matter at all. You can never imagine how powerful the Xiao family is."
There was a glint of arrogance in Xiao Xuan's eyes.
