Manbao didn't nod, but she also didn't shake her head. Bai Shan, who was used to her ways, drew his own conclusion—that must be it.
Bai Shan couldn't resist his curiosity, "What kind of poison is that, so potent that even Director Xiao and the others didn't detect it?"
Manbao carefully described the appearance of that stone, and then said, "It's said that if you live near that stone, you'll be poisoned even if you aren't directly exposed to its light. Gradually, you'll grow weaker, might have nosebleeds, lose hair, and then unknowingly weaken until you die."
Bai Shan gaped, "It's that toxic?"
Manbao nodded, "This poison can't even be diagnosed, so even a doctor who sees the stone can't determine if it's a poisonous stone."
"With poison this potent, how will you explain that you know the antidote?" Bai Shan said. "You can't exactly say your father gave it to you, can you?"
