The earth trembled as the walls began to cave in, kicking up clouds of dust. The ground shook heavily as though there was an earthquake. Trapped inside, all seven of them invoked their arts and protected themselves, sweeping all the falling rubble away from their bodies.
Swoosh! Sixteen shields expanded and flew out, protecting them from all sides, including the ceiling, so the space around them somehow remained intact. However, it didn't stop the rumbling noises coming from all around them.
Small grains of dirt and rock cascaded down the gaps between the shields overhead. Dong Quan gasped, "These demons are trying to bury us alive!"
They were at least a hundred meters underground. If such a major cave-in were to crash down on them, they wouldn't be able to withstand it with their cultivation.
Tan Lao looked to Gu Sanzheng. "It seems like we won't be able to find them using the underground path anymore. We should head out!"
