Chu Yan clenched his teeth against the pain in his arm, trying to untie the tight knots, again and again; undoing just one took quite a while.
Worried that the two men would return soon, Chu Yan became somewhat anxious, his movements frantic, his face slicked with sweat.
Chen Zhi was also concerned about their return, constantly watching the door, ready to seize the moment to act.
After spending more than ten minutes, Chu Yan finally untied Chen Zhi's ropes. Chen Zhi tore off the tape from her mouth and helped Chu Yan remove his as well.
Then, without bothering to untie the ropes on her own legs, she hurried to help untie the ropes on Chu Yan's hands.
"Chu Yan, I'm sorry, it's all my fault you're involved," Chen Zhi said to him, filled with guilt.
Chu Yan gave a slight smile, "Don't talk like that. I'm glad I came with you; otherwise, it would've been very dangerous for you alone."
Chen Zhi glanced at him and bit her lip, saying nothing.
