White Feather City is located on the edge of the Chaotic Sea, and it's easy to develop one's power there without attracting much attention.
Although King Anyuan has discovered Lu Chen's return, even if he leaks the news, White Feather City is far from the Tianxia Immortal Dynasty. The dynasty's army would take a long time to arrive, giving White Feather City ample time to prepare.
Upon hearing Lu Chen's words, Lu Zhengze looked at the distant Purple Moon City and asked, "My lord, now that we have taken Purple Moon City, I'm afraid King Anyuan will soon realize we have seen through his plan. He might make another move soon."
Lu Chen replied, "I actually think he won't take any action. After all, I haven't fully developed yet. He wants to use me to get rid of Lu Jingfu. If I didn't have some strength, how could I help him get rid of Lu Jingfu?"
