The area around this volcano was wrapped in a barrier, so people outside it couldn't sense what was happening within.
But when Chen Changan entered the barrier, he found the situation inside rather surprising.
The extreme heat made even Chen Changan feel uncomfortably hot.

"He might as well leave it for you as a
