Poison, this thing, is actually quite interesting; it's not just those substances that cause intestines to rupture and immediate death upon inhalation that can be called poison. It can be said to be present in every corner of life, like Gou Niaotai in the corner of the wall, peanuts in the fridge, half-burnt wires, and spoiled pig liver. Identifying exactly what poison has been encountered is immensely difficult, covering the entire field of chemistry. Even on Gu Tao's home planet, they could only determine various strange toxins through a process of elimination. After all, the more advanced the technology, the easier it is for unidentified toxins to be inadvertently discovered and used.
