The moment he stepped into the magma zone:
"Boom..."
Zhang Yao felt a surging wave of heat hitting him, his magical power rapidly depleting at a rate more than ten times faster than before.
Even with the double barrier of the spiritual artifact and Daoist technique, he could still feel the overwhelming pressure. One could imagine that if someone fell in without any protection, even an iron man would be dissolved in an instant.
"I can still hold on."
Zhang Yao sensed the rate of magical power depletion and felt slightly relieved.
The temperature and destructive force within the magma would not vary much. If it were just at this level, he could at least withstand for over half an hour.
"There!"
Zhang Yao cast a spell, a thin five-colored glow flashed at his fingertips.
All he could see was a crimson red, his vision obstructed, and his divine thought greatly suppressed, barely covering a distance of several dozen feet.
