As Lu Yingying spoke, she tried her best to shake Feng Qing's hand. She felt that as long as Feng Qing exerted any strength, she would fall into suffocation again. However, she had good thoughts, but her hands could not exert any strength at all. Even her feet started to tremble. If not for her determination, she would have knelt on the ground.
The corners of Feng Qing's mouth curled up. Just as she strangled Lu Yingying's neck, she sprayed a small amount of knockout powder on the other party's face. The anesthetic dosage was controlled very well. It did not make Lu Yingying faint immediately, nor did it make her unable to use her hands and feet. Feng Qing released her grip on her neck when the drug had taken effect.
