When Zhong Yue cultivated the seventh secret realm, he had this feeling that the space was untrue before him, as if he could travel and roam the universe without the confines of space restricting his movements.
Then, as time progressed, his cultivation deepened. In addition to the knowledge of the seventh secret realm from the ancient monarchs contained in the Ancestral Court, as well as Dao Venerate Fu Min's attainments in the Seven Paths Reincarnation, he managed to cultivate his second seventh secret realm, achieving two types of Seven Paths Reincarnation.
With it, his perception of time and space also changed. Sometimes, he would feel that he had already experienced certain things before when in reality, he hadn't. This was because of his Time Secret Realm that allowed him to glance into the future from time to time, thus, causing him to mistake the future for the past.
