After getting off the train, Xiao Furen and Yuan Si deliberately dawdled, falling in behind the human traffickers.
"These people are really organized and disciplined, and they're so vigilant. We were on the train for so long, and I didn't see them interact at all. They didn't even group up on their way out. They haven't slipped up once. If you hadn't seen that woman with the headscarf twice, we never would have been on alert. Just watching them get on and off, who would ever suspect they were human traffickers?" Xiao Furen said, carrying two small bundles as he walked beside his wife. He could no longer see the traffickers; they had deliberately created some distance to avoid tipping them off.
"They did communicate with each other," Yuan Si said suddenly.
"What? When?" Xiao Furen asked, astonished.
