Chen Fei swiftly arrived in front of the mountain cave, sensing a faint residue of aura in the surroundings.
When compared, it did indeed bear some resemblance to the lingering aura left at Moyang Manor.
If Chen Fei hadn't possessed the black thread, he might have mistakenly believed that both auras belonged to the same person.
However, he couldn't help but wonder why there was a similar aura here. If the thief was here, then whose was the black thread in his possession?
"Elder Fang, have you investigated inside?" Chen Fei turned to look at Fang Zhehua standing beside him.
"I've looked inside, but the cave is a complex maze with many intersections. If I go in alone, I might startle them," Fang Zhehua replied, lowering his voice. "Now, it's just the two of us here. I'll be straightforward. Whoever infiltrated Moyang Manor must have stolen quite a lot to attract the attention of the Immortal Cloud Sword Sect."
