Qin Yu's expression changed slightly; Bai Cao Ku was a potent poison, and drinking just a small bottle cap's worth was almost akin to being sentenced to death.
The most terrifying aspect of this poison was that it was incurable, yet it did not lead to immediate death.
Instead, it allowed a person to experience the agony of death bit by bit, while fully conscious.
Over a few days, it would cause gradual organ failure until fibrosis of the lungs finally suffocated the victim alive.
It was often said that it would give you time to regret, but not a chance for a do-over.
Ji Chang brought Qin Yu into a room where seven or eight people were already standing.
On the bed laid a little boy around five or six years old, already tortured by sickness to the point of being unrecognizable.
A middle-aged man with thick eyebrows and lips, about fifty or so, stood in front of the bed, radiating a daunting aura of authority. He must be the Wei Family Head, Wei Zheng.
