Chapter 140: Opening the Blind Box_2

Lin Wu's drone was circling above the observation post when he discovered that this place used to be a radar station. A towering signal tower, two vehicles topped with radar, and a two-story building that covered dozens of square meters in the middle. The entire observation post spanned about four hundred square meters, surrounded by railings, with two artillery pieces parked on the side facing the road. Besides, there were a few scattered soldier zombies.

Shana was about to step up the stairs with her hand on the railing when Lin Wu pulled her back, signaling her to wait. Lin Wu lowered the drone to take a closer look at the entrance formed by four stacked containers, but found nothing out of place.

"We haven't encountered any danger on our way here," Lin Wu said. "Either someone has reached the observation post before us, or there's a trap."

Shana asked, "Did the drone find any automatic sensing guns?"

Lin Wu shook his head. "No, but it reminded me of a joke."

"Hmm?"
