Feng Qing, who had fallen off the cliff, originally wanted to throw out the Five Iron Claws to grab onto the cliff face, but she had been hit by an arrow. The arrow wounded her right shoulder, and although it wasn't fatal, it rendered her unable to move. At this point, she couldn't use the Five Iron Claws to grab the cliff, so she had to follow Han Moyao's plan, first landing on an overhanging platform, then descending to the cave below the platform.
When the arrow was shot at her back earlier, she thought it was someone sent by Han Moyao aiming at her. But later, when stones came flying, diverting the path of the arrow, she realized that the person shooting at her probably wasn't someone from Han Moyao's side.
In fact, it was the people who diverted the arrow with stones who belonged to Han Moyao.
This is why Feng Qing decided to listen to Han Moyao's arrangements when she was in a difficult position.
