Duan Ling Tian was in the Supreme Powerhouse Relic so he did not need to worry about revealing his strength. If he could use the Five Divine Elements now, he would have used it as well.
A Supreme Powerhouse Relic, as its name suggested, was a relic left behind by a supreme powerhouse before his or her death. It was the legacy of a supreme powerhouse. As such, it was definitely free from prying eyes. There were many kinds of legacies that supreme powerhouses left behind. Needless to say, the best was one that had been prepared in advance. Those who obtained such a legacy would become Supreme Gods no matter how bad their talent was. As for those who were highly talented, they could even become supreme powerhouses. Needless to say, such a legacy was rare. Even supreme powerhouses could not predict their own deaths. Moreover, not many supreme powerhouses thought they would die. If they prepared such a place, was it not like cursing themselves to die?
