"Even if there is dictamnus root powder, so what? If you hadn't been wearing silk from Yuanji, nothing would have happened," Qi Shengtian said, puffing out his chest. "Other people who don't wear Yuanji silk bought our powder—why are they perfectly fine?"
"So, Master Qi, you intend to deny everything to the end?" Mu Jinyuan let out a mocking laugh.

You wanted to drive Yuanji Silk to its ruin."
