This karmic thread was none other than the karmic thread between Wu Yun and Su Yu. When Su Yu destroyed Wu Yun's island, a karmic connection would naturally be formed between the two.
After retracting his gaze, Su Yu's figure flashed and disappeared from the sea area.
Since there was already karma involved, Su Yu was not in a hurry to go outside of the central sea area. He wanted to clean up the central sea area first.
At the same time, after the karmic thread connected Wu Yun and Su Yu, she felt as if there was an invisible sharp blade hanging above her head, ready to fall at any moment.
After realizing that this inescapable feeling could not be dispelled, Wu Yun's face instantly turned pale.
At this moment, Wu Yun's intuition told her that Su Yu had a way to find her. Otherwise, she would not have such a feeling.
