A distance of over seven hundred li—under normal circumstances, Ye Zhen could have crossed it in less than two hundred breaths.
If he used Wind Flash Dash or rode Little Cat, he could have gone even faster.
But today, within this underground passage, Ye Zhen took more than an hour to slowly cross those seven hundred-odd li.
Yet even at this speed, his movement still stirred up substantial air currents.
However, Wang Baimu gave Ye Zhen another suggestion.
This suggestion could be said to have been explored by Wang Baimu at the cost of his life.
When he had explored this place before, Wang Baimu had triggered the Tornado Lava Storm five times before discovering a suitable method of passage.
Within that Tornado Lava Storm, Wang Baimu had barely survived by relying on his divine ability to transform into black mist. Yet each time, he had suffered injuries of varying severity and needed time to recuperate before recovering.
It could be said that this method of passage had come at a rather steep price.
The method itself was very simple, though ordinarily no one would have thought of it.
When crossing the lava marsh, one had to fly sideways.

Using this method, the air currents stirred up would be exceedingly weak.
However, upon reaching the alternating hot-and-cold
