As it turned out, when Pei Ming was preparing the IV, he had added some of their drinking water in the glucose.
They weren't stupid, the few soldiers had long realized that the water Ye Xuan gave them to drink was not ordinary. It was just that he never said anything and just told them to use it for drinking. So, they said nothing and pretended to know nothing as well.
This was because of the trust they had in each other. They knew that Ye Xuan would not give them anything that would hurt them, hence, they used the water without any burden.
"Thank you." Those were the two words that Mu Nan said after he was able to talk. It also confirmed their speculation that he was indeed still a human.
