It was rumored that there existed a magic treasure or divine object in Chaotian a long time ago that could make the time go backwards. State Duke Lu had always thought it was nonsense; but he hoped that it was true when he heard Jing Jiu's request; in so doing, he would have the chance to return to the earlier moment and to rescind what he had said earlier.
He was the Chief of Taichang Temple, so it would be easy to let Jing Jiu enter it. However, he was well aware that Jing Jiu wasn't a regular person, and that he wouldn't be interested in entering the regular Taichang Temple seen by the regular folks; what Jing Jiu wanted to enter must be that place.
Besides the strict rules of the imperial court, State Duke Lu couldn't let Jing Jiu take the risk, considering his relationship with the State Duke Manor.
