Without exception, it was still infrared.
They carefully went down one level, and the second level was not as empty as they had imagined.
This floor was obviously a small factory. Everyone was working on something. Fortunately, no one was near the stairs. Moreover, the stairwell was closed. If one did not come specially, they would not be able to see it.
However... These people looked like ordinary workers.
Ning Mengmeng frowned and continued walking.
The third and fourth levels were still the places for processing.
Ning Mengmeng's expression wasn't particularly good. She glanced at Sun Mo. Although she didn't say anything, her eyes showed it.
She was asking, "Are you sure Father-in-law is here?"
Sun Mo nodded solemnly without saying a word, but his meaning was already very obvious.
After reaching the fourth or fifth floor, the infrared rays disappeared. When they went downstairs, it was obviously much smoother than before.
