Although he hasn't shown himself, Xiaochan should have been watching these two places all along. If Wen Wen chooses to swagger to contact both sides, then Xiaochan might notice Wen Wen's plan.
That's why Wen Wen chooses this relatively circumspect way. However, even so, the likelihood of Xiaochan detecting it is still high. So he's just giving it a simple try; if it doesn't work, he still needs Tao Qingqing to act as bait.
Even though Xiaochan is just an Upper Sequence Superpower User, his abilities are relatively troublesome.
According to what Osno knows, Xiaochan's abilities include 'Lullaby,' 'Blood Whip,' 'Blood Filtration,' and 'Cuckoo Invasion.'
Lullaby can put creatures below Disaster Level to sleep but is ineffective against creatures above Disaster Level.
Blood Whip is an offensive ability that allows him to conjure several dark red long whips with substantial power.
