The Divine Beast Alliance was fairly strong. Especially after they gained temporary bases to use, and with Ling Tian and the others allied with them to coordinate and direct their efforts, the Outer Realm Demon Race cultivators suffered numerous casualties when they tried to force their way in. In the end, they had no choice but to give up. They had even deterred Po Di and the others so thoroughly that they didn't dare make a move.
That's right. After learning that Ling Tian and the others had allied with the Divine Beast Alliance, Po Di and Po Family's Youngest Brother had guessed that Ling Tian and the others would use the temporary bases to hold them off. Forcing their way in under those circumstances would result in heavy casualties, so Po Di and the others didn't attack at all. They even withdrew from the northern region of the God Realm at the first opportunity and went elsewhere to capture Ancient Divine Beasts that hadn't joined the Divine Beast Alliance.
As for the Outer Realm Demon Race cultivators, they didn't immediately dispatch their super-large Universe Flying Saucers to attack after their defeat. They went to other parts of the God Realm to capture Ancient Divine Beasts, intending to build up their strength before making another move. Of course, they also wanted to wait for a better opportunity—for example, when Ling Tian and the others reversed their golden cores. That would undoubtedly be the best time to strike.

But they didn't sit idle. They had the alliance's cultivators use the temporary bases to cultivate the Sacred Beast Seven-Style
