Chapter 668: Arriving at Cangwu Mountain, Father and Son Meet!

Mo Han nodded. "There's no rush. You can set out once you're properly prepared....."

Yuwen Cheng drew a deep breath and immediately produced a crystal-clear round bead, crushing it in his hand.

It contained a wisp of Yuan power left behind by Senior Brother Zhang Long; once crushed, it would surely alert the other party and summon him back to the National Preceptor's Residence!

Barely a few dozen breaths had passed since the bead was crushed.

Zhang Long appeared in the room in a frantic rush.

Before Zhang Long could even ask, Yuwen Cheng hurriedly handed the letter over.

Zhang Long glanced at it, his pupils suddenly contracting sharply, and he exchanged a look with Yuwen Cheng.

At this moment, silence spoke louder than words; everything lay in the unsaid!

Then Yuwen Cheng looked toward Mo Han and said in a deep voice, "Let's go. We'll go take a look at Cangwu Mountain. I've long heard of the place and wondered what marvels it truly holds....."

Mo Han smiled, casting Yuwen Cheng a faintly meaningful glance. "Heh, you'll understand for yourself when the time comes."
