Before Xue Ren visit his home - the sword world - he is going to find the children of his who were loyal till the end. The fall of his family was known throughout the universe, so Xue Ren was aware the his oldest children were all alive and hidden somewhere.
They couldn't possibly go against the sword god.
And they couldn't even find their mother who was wounded highly... Naturally, the sons of Uris aren't weak, but they only have that divine bloodline whose source of this bloodline are the divinities they were working with for many years.
It was simply impossible for them to go against it.
Even more, to find their mother who gone out to seek the power!
"I will rely on you once again."
"Rely on me as much as you want, Ren. Maybe this is how I am going to find the inheritance of the divine prophet!"
