Rat poison?
Bai Yang immediately started searching.
Nowadays, it's hard to find an old man selling rat poison at a roadside stall, with a circle of dead rats laid out on the ground, quite ceremonial and intimidating. To the rats, this must undoubtedly look like a terrifying sacrificial ritual to an evil deity.
Bai Yang could only turn to the Internet for solutions.
These days, the names of rat poisons are all about fantasy. Bai Yang looked up and spotted a shop named "Rat Exterminator," and before he could even be impressed, another "Rat Extermination Emperor" popped up.
There was also "Death Upon Sight."
Rat poison strong.
Rat King Killer.
Rat Sweeping Ridge.
Wait, it seems like something odd has snuck in.
To ensure long-term preservation, Bai Yang tried to pick inorganic chemical rat poisons, avoiding organic poisons or biological agents like botulinum toxin.
