A powerful wizard or sorcerer could be the main antagonist. They might have a grudge against the man for some past wrong, real or perceived, and used their magic to make him disappear. In the fanfiction, they would try to prevent anyone from finding him and might cast various spells and illusions to thwart the heroes.
The reason why the struggle between Heaven and man disappeared among the night watchmen of Dafeng was that every Heavenly Venerate had to integrate the will of the Heavenly Dao to mend the heavens at the end. The battle between Heaven and Man referred to the battle between the three sects of Dao Sect (Heaven Sect, Earth Sect, and Human Sect). Lord Taixuan was one of his avatars. He drove almost all the descendants of gods and devils out of Nine Regions and founded the three sects of Taoism, Heaven, Earth and Man. Tianzong's clone eventually merged with the Heavenly Dao, and the Heavenly Dao transformed into the second generation supervisor. Although the search results did not clearly mention the specific reason for the disappearance of the struggle between Heaven and man, it could be inferred that this was caused by the process of the Celestial Venerable's integration with the Heavenly Dao to mend the heavens.
