The Fei family appeared peaceful with very few internal struggles because the first branch and Fei Hua Jiang were keeping the reins. They knew they couldn't beat the flawless Fei Hua Jiang, so they supported him.
But now that such a huge flaw had appeared, the other branches would surely have some thoughts about it. Those who had hidden their ambitions would surely use this opportunity to take the reins from the first branch. With Fei Hua Jiang flawed, Fei Min expelled, and Fei Yi Lang banned from the main mansion, it would be easy for them to overpower the first branch.
Then, things would turn for the worst for the Fei family. Once internal conflicts started, they would never have hope of turning the situation around.
How could they win when their businesses were not doing well, their enemies were waiting to attack at any time, and the family members who should be supporting each other were being blinded by ambition and now ruining each other?
