Two clues?
Just a moment ago, Qin Yong was worried that there were no clues at all, but now Lu Chuan suddenly provided two important leads.
"Lu, go ahead, what are the clues?"
Lu Chuan had no intention of keeping them in suspense at this moment; he opened his laptop, connected it to the projector, and began to play.
"Firstly, no pufferfish toxin was found on the buns, nor on the vegetables used for the vegetable soup. However, we detected pufferfish toxin in the vegetable soup."
This point...
Lu Chuan spoke quickly and succinctly, with not much content, but the information conveyed prompted deep thought among everyone.
No toxin found on the buns, none on the vegetables—what does that imply?
If the pufferfish toxin was brought into the construction site canteen externally, there were basically only two possibilities: either on the buns or on the vegetables.
That's also why Qin Yong had the action team investigate the Aihui Farmers' Market.
