Wang Wanqiu's initial objective was indeed to go undercover, and this led her right next to the leader of the Demon Race's Tenth Legion—a significant gain indeed.
But why didn't she feel any happiness about it?
Wang Wanqiu felt that the customs and ways of the Demon Race were too simple.
While operating as an undercover agent within the Demon Race was actually easier than being undercover in the Demon Sect. Back then she wanted to infiltrate the side of Dongfang Hongyue by undercovering in the White Lotus Sect, which involved a lot of effort, including cross-dressing and bribing through gifts to win the favor of elders in the White Lotus Sect to finally gain an identity and mix in.
Then, arriving in the Demon Land, just by saying a few simple words, the Dragon Lord wanted to take her to meet the Demon Emperor.
And also the Demon Ancestor.
