Chapter 392

He Chenguang took a deep breath, suppressing the anxiety in his heart. He slowly reached out to gently pry apart the blades of the ventilation fan. Because the fan had been in a damp environment for a long time, the edges of the blades were slightly rusted, and the connection to the frame was tight. Liang Song wedged his fingers into the gap between the blades and applied pressure, his knuckles turning white from the exertion. Each attempt was accompanied by a faint sound of metal scraping against metal, which sounded exceptionally clear in the silent duct. This kept his nerves tightly wound; every hair on his body stood on end as he remained vigilant against the risk of being discovered by the enemy. With great difficulty, he pried the fan blades apart, revealing the cable duct inside. He quickly pulled the final tracker from his pocket; the small device appeared remarkably delicate in his rough, large hand. His hand trembled slightly, partly due to the prolonged state of tension and partly because he understood the grave importance of the mission this tracker carried. He pressed the tracker firmly into the cable duct, ensuring it adhered securely and would not easily fall off.
