Lu Xiaoyou grabbed the boy by the collar and dragged him back.
At first, the boy struggled, but suddenly he hung his head and began to cough violently, followed by dry heaving and wailing.
Lu Xiaoyou thought the child was faking it, but then she saw his face turn bright red, with deep red bumps forming on his skin.
The boy's throat seemed to be blocked by something; he couldn't breathe. After struggling for a while, his eyes darkened, his legs gave way, and he collapsed onto Lu Xiaoyou's legs.
Lu Xiaoyou laid him flat on the ground, while observing the boy's complexion, she held his wrist to check his pulse.
He was having an allergic reaction and, due to nausea and dry heaving, something from his stomach had risen and was obstructing his airway.
Lu Xiaoyou made a decisive move, took off her brooch, opened the gemstone ring on it, and placed a tiny pill into the boy's mouth.
