The ground suddenly shook violently, with no gradual buildup.
Everyone's first thought was an earthquake—and an extremely powerful one.
Had they not all been Nen users, the violent shaking would probably have knocked them down immediately.
Although the earthquake was fierce, it posed no real threat to them with their Nen defenses.
However—
The countless creatures stampeding toward them from ahead made this sudden earthquake far more troublesome.
Moyu decisively abandoned the idea of hiding the Shadow Space passage underground.
Their only option now was to get everyone into Shadow Space, then have his Shadow Clone carry the "passage" away from the tide of creatures stretching across the horizon.
As his thoughts raced, Moyu lifted his right foot and flicked it forward. A shadow detached from him and landed on the ground, instantly coalescing into a black circle.
"Quick, get inside first."
After manifesting the Shadow Space passage, Moyu hurried them along in a rapid voice.
At his words, everyone swiftly tore their gazes away from the distant tide of creatures and gathered around the Shadow Space passage.
But just then, the black hills roughly two hundred meters ahead abruptly rose amid a deafening roar.
Unsurprisingly, the tremendous noise nearby drew everyone's attention.
"Huh?!"
Seeing the ground ahead suddenly rise, they instinctively assumed the earthquake had compressed and forced up the earth's surface, leaving them alarmed at its intensity.
But a moment later—
The ground raised by the earthquake did not stop at a certain height. Instead, it continued rising at considerable speed.
As it rapidly climbed higher, the earth stood before them like a massive wall, blocking the sunlight and casting a broad shadow over everyone.
"Ying, ying—"
Before anyone could grasp what was happening, a strange, childish sound came from the "massive wall" rising out of the ground.
