Zhou Lingyi sat in the pavilion outside Second Senior Brother Zheng Jiujang's house, releasing the invisible red thread.
"My Perception would be great if it were as sharp as my brother's."
Zhou Xuan's Perception was strong. Although not yet at the level of two incense, he could already listen in all directions and see the yin and yang, able to scout the surroundings unseen and without a trace.
Unlike her, she needed the red thread as a medium to probe. Although ordinary people couldn't see the thread, if someone very knowledgeable, especially an expert whose Incense Fire Level was not much different from hers,
not only could they detect her red thread, they could even use the thread as a vine, using their spiritual practices to entangle and climb along it, gaining the upper hand by reaching her first...
Fortunately, her senior brothers' spiritual practices posed no threat to Zhou Lingyi.
The red thread slowly climbed up to the window of Zheng Jiujang's house.
