There's no problem with free-ranging dragons that are in their Complete Period.
They can identify dangers on their own, and if they encounter something delicious, they'll go for it directly. If they run into something too formidable for them to handle, they can always run back and call for their brothers and sisters.
However, the Moon Honoring, Star Responding White Dragon, Heavenly Slaughter Dragon, Yama Dragon, Azure Phoenix Green Phoenix Dragon, and Refining Ash Black Dragon are unlikely to encounter any trouble; their strength is already at the top tier in the Tian Shu God Domain.
The Little Gold Dragon and the Peach Demon Deer Dragon require more of Zhu Minglang's attention, so while most of the other dragons move about freely, Zhu Minglang follows the two leisurely, guarding them like preventing wolves from a flock of lambs and calves.
