Qin Shi did not notice everyone's reactions.
At this moment, his attention was entirely on the box on the ground.
This wooden box was dug out together when he discovered the Blue Heart Vine, it was a mechanical box. Because Qin Shi couldn't find a way to open it at first, he kept it in his backpack and hadn't taken it out to look at it again.
If it hadn't fallen out now, he would have almost forgotten about this box.
Just as Qin Shi was about to bend down to pick it up, the box suddenly emitted a faint mechanical sound.
"Hmm?"
The mechanical sound was very soft, others didn't hear it, but Qin Shi, with sharp ears and keen eyes, felt it.
Curiously picking up the wooden box in his hand, he recalled that when the box fell, it rolled on the ground a few times, seemingly following some pattern. He closed his eyes and recalled in detail, and some knowledge of mechanical techniques flashed through his mind.
Then he tapped on the four sides of the wooden box.
