What Anon said before was either his speculation or misinterpretation of the spoilers (i.e., we only know that Lo Po Bia family is one of the 10 Great Families, it's still unclear whether their Family Head is one of the 10 Great Warriors), and both Snakehead's and my comments came only after the chapter itself had been released to avoid spoilers.

As for the source, I admit that I was aware of this since the summary of the preview was available.
