With a tremendous rumble, a terrifying wave of Mental Shock burst from the horn-shaped opening!
The shock wave was visible to the naked eye as it exploded amid the fungal tide ahead!
It wasn't simply a mental storm. It was a high-frequency sonic boom emitted by the twelve Sound Pillars.
Where the shock wave passed, space itself seemed to tremble and warp.
The dark golden mycelium ahead took a devastating blow. Countless tiny ripples burst across its surface.
It was like glasswork smashed by an invisible giant hammer. The mental connections on its surface were brutally severed, and the fungal citizens' consciousnesses within vanished before they could even scream.
The Four Tomb Masters were all shaken by this terrifying power.

At the same time, the other three Tomb Masters were astonished that the North Tomb Master had been hiding such a powerful weapon.

This time, the army didn't continue charging ahead alone. After tearing open the gap, it quickly swept sideways, widening it further.
At this rate, breaking through the Four Great Protectors' defenses and storming into the Upper Tomb was all but
