Chapter 901: Smart City?

Ever since Lu Zhou's bedroom door was closed, Xiao Tong's attention had been glued to his bedroom.

Even though her mom warned her not to disturb her brother, when her parents were not watching, Xiao Tong secretly walked over there.

She gulped and pressed her ear on the door.

Hmm…

Why is it so quiet?

Isn't it supposed to be very loud?

While Xiao Tong was still pondering, that door opened…

"Ouch!"

Xiao Tong took half a step back and covered her forehead.

Lu Zhou froze for a second and looked at his sister.

"What are you doing?"

"Nothing…" Xiao Tong looked at Lu Zhou, then looked at Chen Yushan, and even though her forehead was hurting badly, she still curiously said, "Brother… You guys were in there for a while… What were you doing?"

"Discussing some stuff."
