In the abandoned shopping mall, it was so quiet that you could hear the dust falling.
Sunlight shines in from the holes in the ceiling, forming beams of light, with countless tiny particles flying up and down in the beams.
"Zhang Heng, you just used three rounds of bullets to deal with a low-level 'rotten dog'. Do you know how much a 7.62Mm rifle round costs on the black market now?"
A crisp and fussy voice broke the tranquility here.
Zhang Heng didn't look back. He was squatting half-crouching, using the tactical dagger in his hand to skillfully pry open the Rotten Dog's skull, looking for the gray crystal core the size of a grain of rice.
He has long been used to it.
Ever since this girl named Lin Xia was dug out of the dead half a month ago, his ears have never been quiet.
"I found it. You're lucky. This one has mutated quite thoroughly." Zhang Heng picked up the crystal core that exuded weak energy, wiped it on his blood-stained pants, and then threw it back without looking back.
A small pale hand accurately caught the crystal core, and then quickly put it into a small leather wallet that looked very old.
