Chapitre 1119: Chapter 112: Snake Pill_1

William Cole was somewhat surprised, "You carry a listening device with you?"

"Is that not allowed?"

Ruth Dawn countered with a question, "I can't develop as many pawns under me as you do."

"I can only rely on myself, using the most primitive methods."

With resignation, William Cole shook his head, "Have you also installed a listening device near me?"

"Guess?"

Ruth Dawn looked at William Cole with a smile.

"Sizzle sizzle sizzle—"

Before William Cole could speak, a crackling noise came from the listening device. Ruth Dawn frowned slightly and tossed a wireless earphone to William Cole.

William Cole, seeing the earphone, was rather surprised, "This is a spy-specific listening device from overseas, operating on the principle of radio."

"It uses a button battery and can last for about three hours."

"Because it's so small and convenient to carry, it has sacrificed some communication range, it can eavesdrop only within a 150-meter radius."
