Of course.
He wouldn't admit defeat unless he resisted to the end.
It was only physical pain now. His True Essence and stamina didn't drop. He could still continue, that was right, he could still continue.
Refresh?
Not enough.
God Body couldn't refresh. If he did, he would die. So, he could only refresh True Essence.
He couldn't refresh cultivation techniques too.
With his current situation, his dual cultivation at Initial Five Element Realm allowed him to cross two small realms and crush people at the peak. He could even fight over one large realm. That was also because of all of his cultivation techniques.
Each cultivation technique reached the Return to True Realm which allowed him to have such ability.
