Chapter 602: Chapter 602. Investigation

"Qing'er, look, this is the medicine packet."

 Xiao Zeyu ordered the eunuch to bring back the medicine packets from the medicine storage room for Su Qing to see. Su Qing poured out a packet and checked it. She poured out ten packets in a row. Xiao Zeyu also looked at it together. The ingredients were the same as the prescription. There were no mistakes.

 What was the problem?

 "This realgar is fake."

 Su Qing picked up the realgar and handed it to Xiao Zeyu. The color and shape were very similar and could be passed off as the real thing. Other than realgar, there was also a more valuable medicinal ingredient that had been replaced.

 Xiao Zeyu held the realgar under his nose and sniffed it. His expression changed drastically. They had done such a big thing right under his nose. Because of these two fake medicines, the entire army had been wiped out, and their weapons had been stolen, causing huge losses.
