Their choice was not wrong. What does it matter if someone has high strength or great talent? In the face of major powers, all of that is meaningless. As for the Kashi Family, they simply ignore such strength.
Just as Kaso said, an invitation from the Kashi Family cannot be refused. To openly reject it is to damage the dignity of the Kashi Family, which they will certainly seek to restore. With the current strength of Xin Yun and the others, they definitely lack the power to contest this; they have no other choice but to compromise.
Now, both Speedy Slash and Ke Zhan have become followers of Ka Men. With this, once Xin Yun and the others accept the invitation from the Kashi Family, their status will be on par with Speedy Slash and Ke Zhan. Everyone will be followers of Ka Men, with no one superior or inferior, at least in terms of status.
