Because last night Liu Zixuan sneaked into the Sakura Sect and learned that the guy on the phone understood Star Sea language, he made a slight change to the whole plan. Originally, Nicholas was the most handsome and would accompany Gu Yu inside, but later it was changed to having Huzi accompany him.
The reason is very simple. If there's no one inside who understands Star Sea language, then Nicholas, the most handsome, can embellish Gu Yu's Fortune Telling Skill to make it appear more magical. But the man who made the call yesterday spoke Star Sea fluently, likely being a Star Sea native and familiar with its culture.
So if Nicholas, the most handsome, were to embellish it further, it would obviously seem fake and make the Sakura Sect Leader wary. Having Huzi go is different; although Huzi is rather rough, he's quite reserved and wouldn't deliberately say anything that might accidentally give them away due to the language barrier.
Outside the Sakura Sect.
