Chen Yan reported his reasoning to Lin Gang.
"Your reasoning is very reasonable." Lin Gang nodded.
"Our original next step was to trace the source of the drug and break the chain. Only then would the case be completely closed."
Lin Gang originally wanted to get some clues from Zhang Cunshu.
After all, it was impossible for him to advance the drug trial by himself.
At the very least, the source of the medicine was not that simple.
Moreover, Lin Gang and the others did not find any residual drugs in Zhang Cunshu's clinic.
There was only the blue transparent bottle that Chen Yan had found.
This was a little strange.
A new drug testing lab, and there was actually no drug left.
This didn't make sense.
Then, where did the drugs come from when they were conducting the drug experiments?
Who sent it?
It was either made locally or smuggled from Sun Country.
These were all suspicious points.
