Heh heh so... we've got a little problem

Jiang Cheng takes a curse meant for Lan Sizhui and is turned into a 3 year old. The baby Sandu Shengshou proceeds to cry his little eyes out because he's surrounded by strangers and he wants his parents. They call Wei Wuxian for help and wonder of wonders, mini Sect Leader Jiang recognises him! Except, not in the way that anyone expected.
