"It's obvious who's the most suspicious. Prince and Princess Zi stayed in the palace last night." Su Shenfan had already asked around before he arrived.
Xiao Jingyun gritted his teeth. "They won't admit it and insist that they had been sleeping last night."
"Weren't your people able to find any traces of them coming out?" Su Shenfan smiled mockingly.
A group of people had done who knew what in his territory and his people hadn't even noticed a thing. This kind of thing wouldn't happen in the Earthly Residence at all.
Actually, it wasn't because Xiao Jingyun's defenses weren't tight.
It was just that he didn't want too many people to know about the pill refinement, so he didn't want to make it look like he had bolstered the defenses.
Thus, he had specially removed a lot of guards to make it look like there was nothing happening in the palace.
