The commotion in the secret training room had already alerted Chu Xia and Lai Chun, who were on guard outside.
Even though the secret training room in the Crown Prince's bedchamber was made of a special boulder that could isolate sound, the commotion caused by Zhu Wuwan's practice was so great that it had already faintly shaken the secret training room.
"The secret training room seems to be moving?"
Laichun, who had accidentally touched the outer wall of the secret cultivation room, was stunned. She touched it in surprise and stuck her exquisite little face to it. Now, she felt it even more clearly.
Chu Xia also pressed her face against the secret training room. At the same time, she took out a small earpiece and placed it on the outer wall.
"Rumble…" Rumble…"
Chu Xia heard the clear sound of thunder and her face changed. She widened her eyes in disbelief.
"What's wrong?"
Chu Xia's unusual behavior alarmed Lai Chun, who could not help but look over.
