Why was there poisoning?
"Gas." Xia Weibao opened the Gu poison on the coffee table and poured a drop of the liquid onto the back of her hand.
The drop evaporated quickly, in no time.
She waved her hand, and a scent filled the air, the poison was neutralized.
"Gu poison is a very ancient and deadly poison. Because it's so evil, it was lost to time, I don't know how the person behind this knew about it.
The only thing for sure is that this person is a poison expert."
At first, she didn't associate Yan Weiyang's death with Gu poison, after all, it is a poison that was lost over a thousand years ago.
When she was wandering in Jianghu, no one knew about this poison anymore.
If it weren't for her master being a Poison Doctor, adept at all poisons in the world, she wouldn't have known either.
In these recent days, while helping Yan Lingyi detoxify, she found that Yan Fei was also poisoned.
That's when she started thinking in this direction.
