The two of them circled around the four houses and quickly determined that two of them were occupied. These guards did not have any sort of nightlife, although they did not sleep soundly, but since Long Yueling and Yingsuiyue did not make any sound when they walked, it was natural that they did not notice.
Standing behind one of the rooms, Long Yueling pointed inside, indicating that Yingsuiyue should immediately use her vitality to kill him. After the signal, she stood behind another person's room, ready to make her move.
Yingsuiyue's speed was obviously much faster than Long Yueling's. Just as Long Yueling was about to gather her Qi and attack, she heard a whistling sound, and it was extremely short. It pierced through the paper window and instantly cut open the neck of the person who was sleeping.
