From the perfect water-controlling ability that Zhu Yan had just shown, Tang Li Xue's perfect copy was already more than 80% sure that Zhu Yan's true identity was actually Sea Beast Princess Yan Fei.
Of course, there were also some possibilities which Zhu Yan had only mastered a water-controlling type spell at the consummation level, so Tang Li Xue's perfect copy did not immediately conclude that Zhu Yan was 100% definitely Princess Yan Fei.
Well, it would not be funny if she kidnapped the wrong person and brought her back to meet Instructor Mei Lan, right?
If that really happened, Instructor Mei Lan might hang her upside down on the pole and beat her up so badly until all of her bones broke to pieces out of anger...
So, Tang Li Xue's perfect copy decided to observe Zhu Yan closely for a few more days to ensure she was really the Sea Beast Princess Yan Fei they were looking for.
