How effective are these charms against vampires?

Jiang Hao thought for a while and took out a talisman from the space. There are several ways to cast the talisman. Burn it into talisman water, burn it to activate spiritual power, or directly activate it with your hand. Jiang Hao holds a sword with his hand.

Pointing out very covertly, a stream of spiritual power shot toward Jasper.

Jasper's body suddenly paused, and then he vomited deeply. The sound was so loud that the teacher stopped teaching, and other students also looked at Jasper.

"Jasper, what's wrong with you?" Alice asked concerned.

"Ugh~~!"

Jasper retched again, then stood up suddenly and ran out. Soon he rushed into the bathroom and lay on the sink, only to find that the strong vomiting feeling just now seemed to have passed.

what happened?

Jasper was very confused. He was a vampire and could not be sick. How could he be retching for no reason? This situation was so weird.

Jiang Hao, who was sitting in the back seat, smiled with satisfaction. It seemed that the vomiting talisman was useful for vampires. He had another way to deal with them. He was waiting for the opportunity to continue experimenting, always using the talismans he had mastered on these vampires.
