Time flew by. In the blink of an eye, Zhang Tie and Yan Feiqing had stayed in the tower of time for over 7 years...
7 years inside the tower of time was equal to 7 days outside. During the past 7 years, nothing happened in the tower of time except for what Zhang Tie had done for Yan Feiqing, which meant that the heavenly demon knight, who was chasing them, didn't find this tower of time.
After 7 days, the heavenly demon knight lost its possible spiritual grasp of Yan Feiqing completely. From then on, it would not sense Yan Feiqing's location anymore. Therefore, it could only leave that underground space. As a high-level battle force among demon corps, of course heavenly demon knight couldn't loaf around in the underground space aimlessly. It failed to find Yan Feiqing when he might sense Yan Feiqing's location, not to mention that when it lost its possible spiritual grasp of her.
