He knew of the Song of the Wind.
It was a peerless scripture Xiao Chen had brought out from the Tomb of the Wind Lord.
Xiao Chen had mentioned before that he would pass it on to them when the time came.
They had thought Xiao Chen was joking.
After all, it was a peerless scripture handed down by a god.

Let alone brothers with no blood ties like them—even a father and son might not be willing to share it.
