Even though the two abilities would make any Soul Cultivator green and purple in jealousy, they weren't enough to topple the current situation.
It just made Eric's situation a bit better, helped him relieve a bit of his burden, but he was still under the fire.
The miniature Earth in the self-decomposing Soul Space was trying to grind and crash harder on the barrier, while the only thing working in his help was the self-decomposing space.
Eric didn't need to destroy the Earth's Core Avatar!
No!
That would be such a waste of great opportunity, as he had other plans for the Earth's Core Avatar, but it would only take shape if it tried to take over Hidden Phoenix's body.
For that reason, even though he wasn't winning, as long as his burden was relieved, and as long as he managed to hang on, it was perfect for him.
