Question VW: Peerless White Emperor which chapter question

So I want to re-read the novel again but I don't remember which chapter it was (I forgot to check the button thingy and the latest was 300ish so it doesn't help at all or it may or may be far ahead). the scene I remember was, Ye Cang somehow or another turn into void beast or something void then fight(?) against salvation or 10,000 something group. that's all I remember so pls help me if you know which chapter it is. thanks, Cheers~
