Ryu found a place of seclusion not far away. By this point, Lysander had already left and only Veridia was left behind. The Dragonness didn't have any intentions of leaving anytime soon because there truly wasn't much else she could do.
Dao Gods didn't have all the time in the world to just lounge around and do as they pleased, or more accurately, human Dao Gods didn't. Many human Dao Gods, or humanoids in general, spent a lot of their time in secluded cultivation.
Beasts, however, didn't go into "closed door cultivation". If there was anything analogous, it would be the long slumbers and hibernations they tended to go into from time to time. Then there were those who spent long periods of time in battle to hone themselves.
