Chapter 378: Thunder Prison Array, Suppressing Wang Yuan

Inside the Ninth Mountain.

Dark clouds circled and gathered, then dissipated; so gloomy it seemed as if a black curtain shrouded a thousand-mile radius.

Silver serpents intertwined; thunder cracked sharply.

Occasional thunderstorms appeared, becoming more frequent and denser the deeper into the region one ventured.

Even Foundation Establishment True Cultivators, once struck, could suffer minor injuries.

If one encountered those incessant, widespread thunderstorms, even the strongest Foundation Establishment True Cultivator would fall within them.

Perhaps only Golden Core Ascendant Masters could barely withstand it.

But that was only a possibility.

This was the might of heaven and earth's nature!

Even if it was not deliberately targeting powerful cultivators drawing in power, it was not something ordinary people could underestimate.

It was hard to imagine, if the rumored Nascent Soul Tribulation occurred, what level the Heavenly punishment through thunder would reach.
