From the expression on Li Qingyun's face, Lin Tian knew there was no such thing as "human poison," but he didn't find Xiao Manxuan's words amusing. A Gu Worm is created by placing hundreds of insects into a pottery jar to devour each other, mixed with Gu Medicine, until only one remains.
However, some powers train assassins in a similar manner by putting a group of people into a closed area, and the last person standing is the most formidable assassin. This method of cultivating assassins is strikingly similar to the techniques used in Gu arts.
So, what's wrong with calling such an assassin "human poison"?
As Xiao Manxuan asked her question, the footsteps and voices of the approaching people grew louder, sounding like three individuals, and all of them young.
"Granny, from the footsteps and conversation, they don't seem to be enemies. It's likely drug users from this abandoned old town—probably young people who wander around at night," Li Yue said, frowning.
