"So, what did you find out?" Mavreth didn't even let Michelle say a word when she came to his office. He just straight up asked her about her findings.
Michelle placed the bottle with poison on Mavreth's table. "I don't know all the ingredients, but the main ingredient is the bodies of the Shadow Slimes. The poison works upon contact with the victim's skin after being mixed with water."
Not waiting for Mavreth to tell her to sit down, Michelle lazily plopped onto a chair. "The effects are weak against Shadow Masters because Shadow Slimes, too, are Shadow Masters."
"As for Soul and Spirit Masters, the effect would probably be non-fatal if they don't have the poison element. The poison would get through their skin and enter the spirit veins."
"In the spirit veins, it would block the flow of spirit energy, preventing the cultivator from using any skills, making them vulnerable. With Soul Masters, it probably works similarly."
