There were only two years left before the chaotic region on the Realm Battlefield, formed by the intersection of multiple Realms of Gods, opened. As such, Duan Ling Tian did not have much time left and could only spare a year to search for Linghu Ren Feng and Linghu Chu Yin. After all, he still had many preparations to make before the chaotic region appeared. Moreover, if he could not find them in a year, it was likely he would not find them even if he searched for them another year. There was also a chance that Linghu Ren Feng would enter the chaotic region with Linghu Chu Yin.
In the following year, Duan Ling Tian wandered the periphery of the inner area, focused on searching for Linghu Ren Feng. Even when he ran into people from the Sanction Land, he did not bother to kill them.
