For Han Chenggang to enter a light hypnotic state, Du Lingjiang used the most common and effective hypnotic method available today: the 4-7-8 breathing technique. The general steps involved inhaling for four seconds, holding the breath for seven seconds, and then exhaling for eight seconds. Coupled with the hypnotist's verbal guidance, most people would fall into a light hypnotic state after cycling through the process three times, which is approximately one minute.
But Han Chenggang…
One minute, two minutes…
After a full ten minutes, Du Lingjiang's face began to break into a cold sweat, yet Han Chenggang still had his eyes wide open, staring motionlessly at Du Lingjiang.
"Can… can you cooperate a little?"
Du Lingjiang thought Han Chenggang was doing it on purpose to spite him, glaring with his eyes and growling in a low voice.
"Mr. Du, I can assure you, my brother here is already being very cooperative!"
Yang Yifeng said.
