Apparently it doesn't "officially" happen yet for a few more chapters, according to the comments. BUT, he pretty much knows that Wo Wo is his son. He's just waiting for Ci Nian to finally open up and tell him. That's my take on it anyways. Seriously, I wish I waited a bit longer to get caught up. Chapter 69 was an unfortunate place to stop at. Being in the middle of an argument, and it ends right after he shouts THAT out at him.(〜￣△￣)〜 ╮(￣▽￣)╭
