Bang!
The green gold was not a tough material and only 1 inch thick. With Han Sen's strike, a six-foot-tall 1-foot-wide opening suddenly appeared.
Han Sen looked inside the opening warily with the diamond sword in his hand and was dumbstruck by what he saw. It was an underground metropolitan bathed in green light. The roof was decorated with millions of pieces of gleaming green gold, like an entire green galaxy.
All sorts of black rock cells crisscrossed like a labyrinth. There was nothing artificial. They were more like some hornet nests, both random and regular at the same time.
Han Sen knew that these cells constituted the so-called nest. In each cell there might be a creature. Once the creature noticed his presence, it would try to kill him without a second thought.
