"Little martial sister didn't come?" Little Beiyan suddenly felt his life was shrouded in darkness.

This was Cao Zhen's first time entering the Hidden Dragon Three Sons' residence. He glanced around the room but didn't see the other three disciples. Curious, he asked, "Where are the other three?"

"Senior brother and senior sister are cultivating in the back," Little Beiyan said with a look of utter desolation, gesturing towards the backyard.

The cultivation area for the Hidden Dragon Three Sons wasn't just this one room; this was merely where they meditated and practiced on regular days. Beyond this room, there was a vast backyard and the place where they resided.

Guided by Little Beiyan, Cao Zhen walked towards the backyard. After only a few steps, he could hear Xiang Ziyu's voice.
