"Do you know about the Illusory Poison?"
The grim-faced Matriarch of the Nether Clan stared at Su Chengyu as she asked.
Su Chengyu sneered and said, "I am a member of the Beitang Family; is there something abnormal about me knowing about the Illusory Poison?"
Xia Country had launched several expeditions to the Dark Sea, with the Beitang Family always being part of the main force. Given their background, the Beitang Family dealt with the Nether Clan more than anyone else, so it was no surprise they knew about the Illusory Poison.
However, the reason Su Chengyu knew about it was that he had indeed been poisoned by it before.
As soon as the poison entered his body, Su Chengyu had recognized its nature, which is why he had strategized that sword strike.
"Hmph! Still trying to deceive me? You are clearly not a member of the Beitang Family! Do you really think I can't see through such tricks?"
