For a couple of days, the underground creatures fed on the zombies that had gathered outside the human bases. The high-leveled ones weren't eating zombies, and neither did they drive the lower-leveled ones closer to the human bases. They endured hunger and fixed their eyes on the human bases, staying motionless.
As they made no move, the people in the bases took no action either.
"Roarrrrrr…"
Those weird-looking underground creatures were either pouncing on the zombie crowd with their teeth bared or already had zombies pressed under their paws. They lowered their heads to chew the zombies; their mouths were filled with black blood, and their teeth were stained with blood, flesh pieces, or brain matter.
"They didn't come straight in, nor did they eat those zombies. I guess they simply want to eat humans." Standing on the fence wall, Xiao Licheng said to Wu Chengyue, who was by his side.
