Initially, Gu Ruoyun's group was supposed to follow the Left Emissary to the Secret Order. However, he had some unexpected matters to attend to at the last minute and had informed them that they could start their journey first. They did not expect that they would end up spending so much effort. Furthermore, the geography of Deity Peak was very complicated. Hence, they had only managed to reach the Secret Order after quite some time.
Chu Luo never thought that the Left Emissary had not left with them first because he had urgent matters. In fact, he had abandoned them on purpose so that they would have a difficult time entering the Secret Order.
