Selfishness was ingrained in most people. Wu Hong Qing, the Temple Master of the Title Temple, naturally did not want Ji You, the Heavenly Emperor of the Given Heaven, to know that Duan Ling Tian possessed all Five Divine Elements. Even if, however unlikely, Ji You was not interested in the Five Divine Elements, there were risks that the information would leak. There was no lack of people who coveted the Five Divine Elements.
Wu Hong Qing knew Ji You had the support of a force from a Realm of Gods. If Ji You learned about Duan Ling Tian's Five Divine Elements, Ji You would definitely inform his backers about this matter once the connection between the Devata Realms and the Realms of Gods was restored.
