After all the silver needles had been used up, the girl opened the porcelain bottle beside her and aimed its mouth at Chen Yan's right knee.
In the blink of an eye, a black insect, about the size of a fingernail, appeared in their view, its antennae twitching.
It crawled excitedly around the silver needles, guided by the powder, and silently burrowed into several small holes left by the needles.
Without leaving any traces, it disappeared beneath the surface of the skin.
"Little Zhi, this thing of yours is truly amazing," Ruan Yuan clicked her tongue lightly, feeling goosebumps rise on her arms.
She hated bugs the most, and the thought of a living, wriggling insect crawling inside the body made her feel a little uncomfortable.
Yu Zhi curled her lips, a trace of pride flashing in her light brown almond-shaped eyes: "It's very powerful."
"Zhizhi, has it succeeded?" A man's deep voice reached her ears.
