"Boy, can you explain to me what the black liquid you've taken out of the food is?" Wang Mu asked Ping Hu.
"Leader, there is dirtiness and pollution in the food we eat. By eating them, our bodies will collect dirtiness and that affects our qi practice. What I did is take the dirtiness out of the food with the same technique as the medicine compounding technique which is used to get rid of the contaminants that are not part of the medicine," said Ping Hu.
"Do you know how to compound medicine?" Wang Mu looked surprised. Many people who heard that did not believe him, especially people from the West House.
"I do. A little," said Ping Hu.
"Good. So everything is clear," Wang Mu said loudly. The students from the two houses nodded.
"There is nothing to explain anymore. Both of you, please dig in." Ping Hu moved his gaze back and forth between Chen Li and Yang Cheng, making the two of them give up on fighting each other and starting to eat.
