Primus descended and landed on the city walls, looking down with indifference. While he could enter the void, taking the Fire Giant with him would be a waste of his effort. He didn't have a Spatial Nature like Ryu did, so entering the void required his raw power, and the more powerful the object he was taking with him, the more effort it took. 

Unfortunately, he couldn't just toss a Dao Sovereign into a spatial ring, it would destroy the space within. While he was a treasure hoarder, that only came to interesting talents and cultivators that caught his attention, in terms of actual wealth, he could be said to be a bit of a pauper, and any wealth he did have was directly invested into his strength.
