Xiao Wugou transmigrates to the Great Yu Dynasty and becomes the Fourth Prince, who was raised outside the palace.
By a twist of fate, the powerful chancellor Wei Wuji arranges for him to impersonate the Fourth Prince and enter the imperial court in his place.
Xiao Wugou plays along and agrees. He uses Wei Wuji to fight the other princes while gathering evidence of Wei Wuji's crimes.
When Wei Wuji realizes Xiao Wugou has slipped out of his control, he exposes him in court for impersonating a prince.
Xiao Wugou gives a cold smile. "I am a prince born to nobility. How could I possibly be an impostor?"
