One, two, a series of heavy boulders fell precisely into the tunnel entrances on the ground.
They marked the smooth, orderly vertical pipe walls with their impact, colliding left and right, spiraling violently towards the chaotic faceless person's base below.
Any of the heavy boulders hitting the faceless person's base would bring total disaster to this hidden structure built in an underground cave complex.
Under Xia Zhou's hopeful gaze, the first heavy boulder, which was about to fall into the base, mysteriously stopped just above a hole in the base ceiling. The boulders above it were also immobilized by an invisible force.
Many fluffy white particles appeared in the air of the underground base.
Light and agile, they slowly drifted and turned in the air, seeming harmless and commonplace, as if they were torn cotton strips wafting in the wind.
