Chapter 816: Master, What’s the Reason for This?

Gu Qingxue took the bottle of blood and sniffed it. As expected, she smelled a faint scent of blood. She could not help but be surprised. "Master, what's the reason for this?"

"The poison in her body is naturally a very important reason, but the most important reason is that your grandmother's body may have hidden a Gu Worm. This is a very big characteristic of people who have been poisoned by Gu Worms. You may not have understood it before, but in the future, don't ignore this." Wen Jiang warned.

Gu Qingxue immediately committed this characteristic to memory. Then, she looked at Wen Jiang and asked, "Master, does everyone's blood smell sour after being poisoned?"
