Zhang Yan, with the assistance of the Little Pot Mirror's Mirror Spirit, could easily connect with his heart and spirit, thus having a grasp over every movement of everyone within the Cave Mansion. When Wang Caiting broke through the Xuan Guang Realm outside the Cave Mansion, he immediately became aware.
Among the Wang Sisters, Wang Caiting had the best talent, surpassing her sister Wang Caiwei by a margin. It wasn't surprising she was the first to step into the Xuan Guang Realm.
However, this also involved differences in cultivation techniques, as it varies from person to person, and faster cultivation is not always better. Take Tian Kun, for instance, who started cultivating earlier than the Wang Sisters, yet is still hovering in the Ming Qi Realm, unable to break through.
But his cultivation method was tailor-made by Gui Congyao for his reincarnated body. Though he seems behind now, Zhang Yan dared to assert that his progress in the future would surpass the Wang Sisters.
