If there was anything more to be done, Atlas would inevitably die.
The moment clarity entered the world inside the Hell Guardian, Atlas' body collapsed.
In the first place, he'd run out of qi some time ago. His body had become a medium through which several types of qi from the surroundings mixed, but his own qi supply was exhausted when he was forced to combat the death qi.
Did the damage he'd taken even have to be mentioned? He was burned, sapped of vitality, and had his arm cut off all in the span of only a few minutes. The mental exhaustion he felt after completely untangling the threads of vitality couldn't just be laughed off either.
When his body sensed that there was no danger in the vicinity, it gave up. His qi left him, his strength left him, and he plummeted to the solid surface below.
Bang!
